Abstract: A retaining device or snap-ring for retaining a mating hub and drum within a transmission is provided. The device is insertable into a groove along the inner circumference of a circular flange and includes a main outer loop, an opening for dividing the snap-ring into two deflectable curvilinear portions and at least partially defined by a tabular extension projecting from each curvilinear member. The tabular extensions provide sufficient surface area for applying deflective or compressive force to the snap-ring and are contoured to facilitate use of a deflection tool. The snap-ring further comprises an externally-projecting secondary loop for reducing deflection force, or an internally-projecting secondary loop for increasing deflection force. The snap-ring may be used within a double-flange hub having a plurality of slots for facilitating insertion of the secondary loop and the tabular extensions within the flange groove.

Abstract: A power transmission has a compound input gearset, a Ravigneaux gearset, five friction type torque-transmitting mechanisms, and a one-way type torque-transmitting mechanism selectively engageable to provide at least six forward speed ratios and one reverse speed ratio for the transmission. The input gearset includes a planet carrier, which is stationary within a transmission housing and connected with a stationary portion of the transmission housing. The planet carrier also includes a central support member which provides nonrotatable housings for the apply pistons for three of the friction type torque-transmitting mechanisms.

Abstract: A roller conveyer transports sheet material to accumulating hoppers provided with rotatable distributing chutes. Chute drivers are electrically connected to a unit for measuring the material thickness via a control unit. The thickness measuring unit comprises a radioisotope thickness gauge including a radiation detector and a radioactive source, positioned on opposite sides of the sheet material between two pairs of drive rollers of the conveyer. A meter measures the average value of the radiation intensity during a period of time within which a single sample of the material being sorted passes through the radiation zone. Another meter measures the instantaneous value of the radiation intensity.

Abstract: An apparatus for contactless measurement of the thickness of a sheet material comprises a radioactive source located in a protective container which has a collimating hole to output a flow of radiation. There is a radiation detector to sense the radiation passed through the material under control, which is electrically connected to a radiation intensity meter, and also compressed air means for delivery of a jet of compressed air to the measurement point.
