  • Patent number: 4555393
    Abstract: A continuous fiber composite having carbon microfibers dispersed in the resin filling the interstices between the continuous fibers to enhance the transverse properties of the composite. The carbon microfibers are made by soaking carbon fibers in an intercalating acid solution comprising a mixture of fuming nitric and sulfuric acid to weaken the intercrystallite bonds. Gentle stirring of solution separates the carbon microfibers from the host fibers. The microfibers are then separated from the intercalating acid solution and washed to remove the residual acid.

  • Patent number: 4535679
    Abstract: A control valve 44 for use in a fluid pressure operated motor 10 to control the communication of fluid between first and second chambers 34 and 36. The control valve 44 includes a plunger 58, a disc 46 and a retainer 70. The retainer 70 has a cylindrical body 82 with an inwardly projecting lip of which section 84 engages and holds the peripheral surface 48 against shoulder 78 on the hub 26 and an end section 94 which acts as a stop to limit the movement of plunger 58 in bore 38 when the valve 44 is in the released position. Tabs 100, 100'. . . 100.sup.N on sleeve or cylinder 82 are located in groove 102 to lock the retainer 70 in place. In response to an input, push rod 56 moves plunger 58 to allow disc 46 to move and initially interrupt communication of a first fluid between the first and second chamber 34 and 36 and thereafter permit a second fluid to flow into the second chamber 36.

  • Patent number: 4531370
    Abstract: A brake actuation assembly 10 having a master cylinder 12 attached to a stationary wall (14) of a vehicle and a power assist apparatus 16. Linkage 66 connects a movable wall 125 in the power assist apparatus 16 with pistons 64 and 68 in chambers 60 and 62 in the master cylinder 12. A valve 133 responds to an input from an operator to allow a pressure differential to be created across wall 125. The pressure differential moves the wall 125 while at the same time the linkage moves pistons 64 and 68 to pressurize fluid in the master cylinder 12. An adjustment mechanism 82 acts on the piston 68 to control the timing of the interruption of fluid communication between a reservoir 46 and chambers 60 and 62 as a direct function of movement of wall 125.

  • Patent number: 4522031
    Abstract: A fluid pressurizing device 10 having a master cylinder 12 with a cylindrical projection 52 that extends through the housing of a brake booster 14. The housing of the brake booster 14 has a front shell 56 located on a shoulder 54 of the cylindrical projection 52 and a rear shell 140 located against a shoulder 150. A nut carried by the cylindrical projection 52 engages the rear shell 140 to compress a bead 111 of a diaphragm 110 against a shoulder 57 on the front shell 56. A sleeve 80 connected to a hub member 70 retains a bead 108 of diaphragm 110 and bead 90 of a diaphragm 92 connected to the cylindrical projection 52. In response to an input force, a valve assembly 136 controls the development of a pressure differential across the diaphragms 92 and 110. The pressure differential acts on and moves the diaphragms 92 and 110 toward the first shell 56.

  • Patent number: 4510752
    Abstract: A master cylinder includes a housing (24) forming a bore (26) for receiving a first piston (38) and a second piston (40). Each piston is movable during braking to generate fluid pressure within a first pressure chamber (54) and a second pressure chamber (58), respectively. The first piston (38) is made from a stamping to define a uniform thin wall therefor. The stamped piston (38) forms a longitudinal body (84) movable relative to a fixed lip seal (32) and a base (86) defining a pocket (88) for receiving an input member (22).

  • Patent number: 4505108
    Abstract: The invention is an integrated hydraulic control circuit for actuating the thrust reversers and variable exhaust nozzle on high preformance gas turbine engine powered aircraft. The hydraulic circuits for both systems are integrated into a single housing and are served by common elements. The circuit for the deployment and stowage of the thrust reverser buckets is hydraulically sequenced inhibiting the application of hydraulic power to the actuators prior to withdrawal of the locking pin. In a like manner, the thrust reversers must be fully retracted before the locking pin is deployed. The hydraulic circuit for the thrust reversers also includes a pressure compensating circuit which reduces the pressure applied to thrust reverser actuators with the thrust reversers in the stowed position.

  • Patent number: 4500144
    Abstract: A bearing member (10) having a series of carbon separators (16, 16' . . . 16.sup.N) with semi-spherical pockets (52, 52' . . . 52.sup.N) on the end thereof and semi-spherical ribs (20) and (22) on its inner and outer periphery. The ribs (20) and (22) are located in grooves (50) and (58), respectively, of races (44) and (43). Balls (14, 14' . . . 14.sup.N) are located between pockets 52, 52' . . . 52.sup.N and maintained in radial alignment in the grooves (50 and 58) of the races (43) and (44). Initially separators (16, 16' . . . 16.sup.N) are separated from each other but as the bearing (10) is used the separators (16, 16' . . . 16.sup.N) wear by providing balls (14, 14' . . . 14.sup.N) and races (43 and 44) with lubrication. At a predetermined wear condition, the separators (16, 16' . . . 16.sup.N) engage each other to provide controlled ball spacing thereafter protecting bearing member (10) from premature wear or total failure.

  • Patent number: 4500111
    Abstract: A suspension assembly couples a wheel assembly (16) and a brake assembly (60) to a frame (10). The suspension assembly includes a support (20) for receiving an axle (24). The axle carries the wheel assembly (16) at one end of the support (20) and forms a drum (46) at the other end of the support (20) for engagement with the brake assembly (60). Therefore, the support (20) separates the wheel assembly (16) from the brake assembly (60) so that the brake assembly (60) brakes the wheel assembly (16) via the axle (24).

  • Patent number: 4493307
    Abstract: A breakerless ignition system in which an electronic advance circuit (30) generates an electrical trigger signal (SPKE) and a mechanical advance circuit generates a mechanical trigger signal (PCP). The mechanical trigger signal (PCP) and electrical trigger signal (SPKE) are combined in a trigger circuit (28) to generate an activation signal to a power switching device (40) which causes an ignition circuit (32) to fire a spark plug (54). In operation the electrical trigger signal (SPKE) normally provides an accurate timing signal to ignite the plug (54) and the trigger circuit (28) masks the mechanical trigger signal (PCP) to prevent double firing. Upon failures or special conditions when the (SPKE) signal is absent the (PCP) signal will provide operation in a back-up mode to ignite plug (54).
