Abstract: A transmission testing apparatus having at least one inertia flywheel having a shaft capable of being coupled to the output shaft of the transmission being tested. The transmission is mounted on a removable plate on one side of an adjustable bulkhead supporting an internal combustion engine on the other side. The engine has an output shaft coupled to the input shaft of the transmission. The bulkhead is pivotally and adjustably positionable such as to align the transmission output shaft with the inertia flywheel shaft. The engine is maintained in an appropriate upright normal position providing correct carburetion and lubrication by being supported by a mounting plate rotatable relative to the bulkhead and held in substantially the same angular position relative to horizontal and vertical reference axes, irrespective of the position of the bulkhead, by a strut pivotally attached to the engine mounting plate at one end and pivotally attached to the support base of the apparatus at its other end.

Abstract: A transmission testing apparatus having at least one inertia flywheel having a shaft capable of being coupled to the output shaft of the transmission being tested. The transmission is mounted on a removable plate on an adjustable bulkhead supporting a prime mover, such as an internal combustion engine, and having an output shaft coupled to the input shaft of the transmission. The bulkhead is adjustably positionable such as to align the transmission output shaft with the inertia flywheel shaft. Alternatively, the apparatus comprises two upright members each provided with a shaft driven inertia flywheel such that each of the output shafts of a transaxle transmission may be coupled each to one of the two inertia flywheels.

Abstract: A filter comprising a housing in which are disposed a filtering element and a bypass channel establishing direct communication between the inlet and the outlet of the filter. The outlet of the bypass is closed below a predetermined temperature by a thermally operated diaphragm member. When the temperature of the fluid flowing through the filter housing reaches the predetermined temperature, the diaphragm member is deformed such as to open the bypass outlet. The filter has particular applications for installing in the line between a motor vehicle automatic transmission and the transmission fluid cooler, after the transmission has been overhauled or when a rebuilt transmission is installed on the motor vehicle.

Abstract: A heat responsive by-pass flow circuit for a fluid flow system passive element, such as the filter element normally connected in series from an inlet to an outlet. The filter element is provided with a head block or housing having a by-pass passageway between the filter element inlet and outlet, such by-pass passageway being normally closed by a spring loaded valve. A solenoid actuates the valve to open the by-pass passageway under the control of a heat controlled switch having a temperature sensitive element disposed in the flow of fluid at the inlet to the filter element. The heat temperature controlled switch is adjusted to open the by-pass at a pre-set temperature of the fluid flowing into the inlet to the filter element, such as to cause increased direct flow of fluid from a cooler to a working element of the system and back to the cooler, thus reducing overheating of the fluid due to slow fluid flow through the system caused by excessive pressure drop across the passive element.
