Yelp and CitySearch both maintain that having a YouTube video on their listing for your company doubles the likelihood that visitors to your listing will take some kind of action such as a phone call to you or a click to your website. Many local search engines now allow you to upload your video information to their sites, including the king of local search, Google.local.

The most important marketing challenge for local businesses used to be location. For many such as restaurants, hotels, and dry cleaners, location is still a critical part of the marketing decision. One of my clients, PV Bicycle Center in Palos Verdes, California, moved his shop a few block into a larger and more visible location and has seen his business almost double the first year and the second year is on the way to similar increases... and all of that during a recession. The second most important challenge used to be how big of an ad to take in the Yellow Pages. You know, that book you now use as a door prop.

The internet has changed the equation for both of these marketing moves if you are a small, local business. Today your location on the first page of internet searches is commonly more important than your location on main street, and your listing on local search engines is the modern equivalent of the Yellow Pages hard copy edition. The current and future king of local search engines is the map at the top of the page that you see when adding a city or zip code to your business type (e.g. Inglewood marketing consultant or mortgage broker 90025). By sheer force of this map's location on a Google search, being seen next to the map may be the most important driving force for new business clients.

But Google.local is not the only local search engine (LSE). There are at least 60 general websites that fall into subcategories such as directories and mobile directories, and include such names as Yellowpages.com, Superpages.com, Yelp, CitySearch, HotFrog, and MerchantCircle. Your potential customers are using these LSE's and others to find information and reviews about your business before they decide to visit. If you aren't listed, they can't find you. If you are listed and have very little content or that content is not compelling, they may shop with your competitor who has good content. Part of that content is Video.

The methods used by LSE's to determine how you rank under your category is complex and different for every one of them. Moreover, they don't tell you what you need to do to have a high ranking other than pay them lots of money for a sponsored position. One thing we do know, the more robust your content the more likely you are to achieve a high ranking. The more compelling your content, the better chance you have that the customer will decide to use you. The obvious conclusion is that you need to have at least one, and preferably more than one compelling YouTube video on the LSE's that allow you to link videos.

Creating a DIY YouTube video is within the reach of most small businesses. The cost in time and money is not huge. However, using a local marketing company to do the video will generally produce results that are much more likely to create action by the viewer. You may be surprised to learn that the cost of a video may be as low as $300, and even less if you do several at a time.

Your video can be used for much more than just an element on the content of a LSE. Other uses include:

• Embed in your website
• Embed in your blog
• Be found on Google searches
• Be found on YouTube searches
• Build trust and authority
• Share information which may result in loyalty

Why YouTube? There are many other video repositories such as DailyMotion. My experience is that YouTube will result in more than double the viewers than all the others combined. The YouTube brand has trust associated with it, and power just from being the biggest and best known brand. Finally, YouTube is owned by Google. 'Nuff said.

Chain Drive

History

Polybolos (reconstruction) described by the Hellenistic writer Philo of Byzantium (3rd century BC). The semi-automated arrow thrower features the earliest known chain drive.

The oldest known application of a chain drive appears in the Polybolos, a repeating crossbow described by the Greek engineer Philon of Byzantium (3rd century BC). Two flat-linked chains were connected to a windlass, which by winding back and forth would automatically fire the machine's arrows until its magazine was empty. Although the device did not transmit power continuously since the chains "did not transmit power from shaft to shaft", the Greek design marks the beginning of the history of the chain drive since "no earlier instance of such a cam is known, and none as complex is known until the 16th century. It is here that the flat-link chain, often attributed to Leonardo da Vinci, actually made its first appearance."

The first continuous power-transmitting chain drive was depicted in the written horological treatise of the Song Dynasty (9601279) Chinese engineer Su Song (1020-1101 AD), who used it to operate the armillary sphere of his astronomical clock tower as well as the clock jack figurines presenting the time of day by mechanically banging gongs and drums. The chain drive itself was given power via the hydraulic works of Su's water clock tank and waterwheel, the latter which acted as a large gear.

The endless power-transmitting chain drive was invented separately in Europe by Jacques de Vaucanson in 1770 for a silk reeling and throwing mill. J. F. Tretz was the first to apply the chain drive to the bicycle in 1869.

Chains versus belts

Drive chains are most often made of metal, while belts are often rubber, plastic, or other substances. Although well-made chains may prove stronger than belts, their greater mass increases drive train inertia.

Drive belts can often slip (unless they have teeth) which means that the output side may not rotate at a precise speed, and some work gets lost to the friction of the belt against its rollers. Teeth on toothed drive belts generally wear faster than links on chains, but wear on rubber or plastic belts and their teeth is often easier to observe; you can often tell a belt is wearing out and about to break more easily than a chain.

Chains are often narrower than belts, and this can make it easier to shift them to larger or smaller gears in order to vary the gear ratio. Multi-speed bicycles with derailleurs make use of this. Also, the more positive meshing of a chain can make it easier to build gears that can increase or shrink in diameter, again altering the gear ratio.

Both can be used to move objects by attaching pockets, buckets, or frames to them; chains are often used to move things vertically by holding them in frames, as in industrial toasters, while belts are good at moving things horizontally in the form of conveyor belts. It is not unusual for the systems to be used in combination; for example the rollers that drive conveyor belts are themselves often driven by drive chains.

Drive shafts are another common method used to move mechanical power around that is sometimes evaluated in comparison to chain drive; in particular shaft drive versus chain drive is a key design decision for most motorcycles. Drive shafts tend to be even tougher and more reliable than chain drive, but weigh even more (robbing more power), and impart rotational torque.

Use in vehicles

Bicycles

Main article: Bicycle chain

Chain drive was the main feature which differentiated the safety bicycle introduced in 1885, with its two equal-sized wheels, from the direct-drive penny-farthing or "high wheeler" type of bicycle. The popularity of the chain-driven safety bicycle brought about the demise of the penny-farthing, and is still a basic feature of bicycle design today.

Automobiles

Transmitting power to the wheels

Chain final drive, 1912 illustration

Chain drive was a popular power transmission system from the earliest days of the automobile. It gained prominence as an alternative to the Systme Panhard with its rigid Hotchkiss driveshaft and universal joints.

A chain drive system uses one or more roller chains to transmit power from a differential to the rear axle. This system allowed for a great deal of vertical axle movement (for example, over bumps), and was simpler to design and build than a rigid driveshaft in a workable suspension. Also, it had less unsprung weight at the rear wheels than the Hotchkiss drive, which would have had the weight of the driveshaft to carry as well, which in turn meant that the tires would last longer.

Frazer Nash were strong proponents of this system using one chain per gear selected by dog clutches. The Frazer Nash chain drive system, (designed for the GN Cyclecar Company by Archibald Frazer-Nash and Henry Ronald Godfrey) was very effective, allowing extremely fast gear selections. The Frazer Nash (or GN) transmission system provided the basis for many "special" racing cars of the 1920s and 1930s, the most famous being Basil Davenport's Spider which held the outright record at the Shelsley Walsh Speed Hill Climb in the 1920s. Frazer Nash cars are still raced in the UK.

Parry-Thomas was killed during a land speed record attempt in his car 'Babs' when the chain final-drive broke, decapitating him.

The last popular chain drive automobile was the Honda S600 of the 1960s.

Inside motors

Internal combustion engines often use chain drive to power the timing chain used to drive overhead camshaft valvetrains. This is an area in which chain drives frequently compete directly with belt drive systems, and an excellent example of some of the differences and similarities between the two approaches. For this application, chains last longer, but are often harder to replace. Being heavier, the chain robs more power, but is also less likely to fail. The camshaft of a four stroke engine must rotate at half crankshaft speed, so some form of reduction gearing is needed and a direct drive from the crankshaft isn't possible. Alternatives to chain drives include gear trains, bevel gear and shaft drives, or toothed flexible belt drives.

Transfer cases

Today, inverted tooth drive chains are commonly used in passenger car and light truck transfer cases.

Motorcycles

Chain drive versus belt drive or use of a driveshaft is a fundamental design decision in motorcycle design; nearly all motorcycles use one of these three designs. See Motorcycle construction for more details.

Can I save my camshaft position sensor?

I have a 1998 buick century 3.1 and the camshaft position sensor is throwing a code and i was wanting to know if i can test it to see if it is still good and if i can how? From what i understand it is a magnetic sensor so i believe that if i were to throughly clean the sensor then it should be ok right? here is a pic of it if it helps any. http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?categoryDisplayName=Engine+Management&fromType=parts&fromString=search&parentId=59-0&currentPage=1&filterByKeyWord=cam+sensor&isSearchByPartNumber=false&navValue=15900158&categoryNValue=15999999&fromWhere=&itemId=158-0&displayName=Camshaft+Position+Sensor&searchText=cam+sensor Thank you.

The new part is $32.99. The TIME required to remove and reinstall the sensor is worth more than that. If you are going to go to the effort, you should just replace the sensor.
