Abstract: A pedicure tool is used for the removal and/or reduction of calluses, dry skin or corns. The pedicure tool has an elongated ergonomic housing with opposing tips of sharp circular edges for scraping calluses, dry skin, or corns in order to remove or reduce them. The pedicure tool also has an elongated internal element or rod with opposite cleaning ends which can be longitudinally mechanically moved externally of the elongated ergonomic housing to clean away any residue left from the scraping of the calluses, dry skin or corns by the sharp circular edges of the opposing tips.

Abstract: There is provided methods for servicing a vehicle's transmission cooling system having inlet and outlet ports. An example method comprises the steps of pumping air into an inlet port of the transmission cooling system to cause transmission fluid to flow out of the outlet port of the transmission cooling system; cycling a solvent through the transmission cooling system, where the solvent enters through the inlet port and exits through the outlet port of the transmission cooling system; re-cycling the solvent exiting through the output port through the transmission cooling system; and pumping air into the inlet port to cause the solvent in the transmission cooling system to exit through the outlet port.

Abstract: Apparatus and method of replacing old fluid in a transmission system by feeding clean fluid into the system from a clean fluid tank using a pump and draining the old fluid into a waste tank and using a processor to monitor the clean fluid pressure in the clean tank and the old fluid pressure in the waste tank and adjusting the pump's speed using the processor such that the old fluid is drained at substantially the same rate as the clean fluid is fed.

Abstract: Method and apparatus for servicing a vehicle's transmission cooling system, where the apparatus includes a source valve with inlet and outlet ports, a pump with inlet and outlet ports, and a return valve with inlet and outlet ports. The pump inlet is connected to the source valve outlet. The pump pumps fluid from the source valve inlet through the source valve outlet and the pump inlet to the pump outlet for servicing the transmission cooling system. The fluid returns from the return valve inlet to the return valve outlet and the pump then re-pumps the fluid into the transmission cooling system. The service apparatus may also include a fluid source and a filter interposed between the fluid source and the source valve, where the fluid returns to the fluid source prior to re-pumping the fluid. The service apparatus may also include a flowmeter interposed between the return valve and the fluid source and a filter interposed between the return valve and the flowmeter.

Abstract: A portable fluid exchanger for flushing the used transmission fluid from a vehicle engine as it replaces it with new fluid is mounted on a wheeled undercarriage and contains a tank of new transmission fluid, hoses, and a 12-volt electrical system which connects to the battery of the vehicle being serviced to power a fluid delivery pump, an output and return flow control system, and means for visually checking the condition of the fluid being pumped from the transmission. The normal continuous-flow circulation system of the vehicle is interrupted by interposing the exchanger in a cooling line of the transmission system, and the vehicle's own pump is used to expel fluid from the transmission while the exchanger introduces new fluid, as the vehicle engine idles. The fluid level in the transmission is gauged by monitoring inflow and outflow to and from the transmission to insure that it remains reasonably full during the flushing process.

Abstract: An internal combustion engine purging system cleans out deposits of carbon and other substances that accumulate over time in the fuel system by delivering a mixture of fuel and cleaning solution into the fuel intake ports while the engine is running, so that the engine pulls the mixture through the carburetor jets or injectors. This purging system is characterized by its virtual universal application with substantially any commercially produced gasoline or diesel engine. It is in part comprised of two separate but overlapping systems, one for gasoline and one for diesel, which are selectable by the operator.
