Publication number: 20070251083Abstract: The present subject matter includes method and apparatus for an insulating layer applied to a battery to effectively increase the insulated separation between the anode and cathode contact surfaces of the battery. This increase in effective separation between anode and cathode decreases the probability that moisture applied to the battery will cause substantial ohmic conductivity between the anode and the cathode. Consequently, fewer batteries will be prematurely depleted or destroyed by moisture and fewer devices holding those batteries will need repair. The present subject matter serves to prevent or eliminate discharge of corrosive battery chemicals due to moisture and operating in wet environments. The life of batteries and devices using the present subject matter is thus extended. Additional method and apparatus can be found in the specification and as provided by the attached claims and their equivalents.Type: ApplicationFiled: April 28, 2006Publication date: November 1, 2007Inventors: Douglas Link, Sidney Higgins, Robert Jacoby

Patent number: 6588119Abstract: A gauge for setting.a pair of tapered roller bearings that are mounted in opposition has a base to which one of the races for one of the bearings is fitted remote from the location that it normally assumes. In addition, the gauge has male and female elements which slide on the base independently of each other and a spring for urging the elements apart. The spring urges one of the elements against a conical envelope on the detached race and the other element against a conical envelope formed by the tapered rollers around the other race that is in its normal operating position. Sensors measure the strain in the spring, and from the strain one can calculate the distance between like diameters on the conical envelopes. The measurement derived from the gauge together with the desired setting for the bearing enables one to calculate the thickness of a spacer which will provide the desired setting for the bearings.Type: GrantFiled: February 26, 2002Date of Patent: July 8, 2003Assignee: The Timken CompanyInventors: Daniel T.
