Abstract: ABSTRACT OF THE DISCLOSURE     In a slider having a body with an island or sepa-rator formed centrally at its flared front end, a locking pawl is arranged between a pair of ears projecting upwardly from the separator in spaced parallelism.  A retainer pin extends between the separator ears over the locking pawl in registered relationship to an upwardly opening recess formed adjacent the front end of the latter. Normally, the locking pawl is yieldably urged, as by a leaf spring mounted thereunder, to releasably engage the retainer pin in its recess and to have its tapered or pointed rear end held in interference contact with the rows of interfitting fastener elements passing through the slider body.  Upon exertion of a pull on a pull tab connected to the locking pawl, the latter will pivot about the retainer pin to permit the free movement of the slider along the fastener elements.

Abstract: A planetary gear system comprises a primary shaft, a propeller shaft, a number of intermediate shafts, a planet support on at least one of the shafts, and at least two planet wheel journals on the planet support.  At least two planet wheel journals each are provided with a planet friction wheel contacting a surrounding friction ring and a friction sun wheel provided on an adjacent shaft.  At least one of the planet wheel journals is provided with a planet gear wheel, which co-operates with a surrounding ring gear, and a sun gear provided on the adjacent shaft.  The intermediate shafts do not have to be provided with bearing and centering means since these functions can be accomplished by the elements of the gear system.

Abstract: ABSTRACT       A hydraulic control system for an automatic trans-mission having a plurality of friction engageable devices to produce a plurality of drive ratios by selective engagement thereof, two of the engageable devices comprising friction brakes engageable to establish a second speed drive ratio through the transmission, and conduit means connecting a source of pressure to each of the brake devices and to an hydraulic accumulator.  The conduit means has a first branch connected to a second of the brake devices, and a logic valve is provided in the conduit means between the branches adapted to interconnect the branches and the respective servomotors for engaging the brake devices, providing equali-zation of the pressures at the brake devices whereby they are engaged with identical engaging force.  The control circuit includes a restriction control valve, in the conduit means for the direct drive or second clutch of the transmission which is connected between the conduit means and an accumulator for the second clutch, providing an unrestricted flow of pressure to the accumulator when the clutch is being engaged and a restricted flow of pressure from the accumulator to the conduit means when the clutch is disengaged whereby disengagement of the clutch may be controlled without waiting for the stored hydraulic energy in the accumulator to be dissipated.
