Abstract: A vacuum brake booster is coupled to a master cylinder at the same time that an output member for the vacuum brake booster is adjusted relative to a piston for the master cylinder. The adjustment is carried out by a plunger adapted to activate a bonding material for bonding the plunger to the output member.

Abstract: A content induced transaction overlap communication system for transmitting data over a single communication channel between a plurality of senders and at least one receiver. The senders simultaneously transmit the highest order bits of their data word, one bit at a time in serial fashion and monitor the state of the communication channel. Transmission of data bits is terminated by all senders which detect a difference between the state of their transmitted data bit and the state of the communication channel. Bit competition performed at the end of each transmitted data word determines among those senders still having data bits remaining to be transmitted which sender has lexicographically the next smallest word and activates that sender to transmit its remaining data bits. This procedure continues until all of the senders have completed the sending of their data word.

The valve assembly includes a sleeve with a bore receiving a first valve member and a second valve member. The valve member cooperates with an input member to define a cavity within the sleeve and a resilient travel block is disposed within the cavity in engagement with the valve member and the input member.

The video signals corresponding to the target returns from consecutive pulse transmissions are converted to digital format and then integrated except that radar return signals from targets within a first range resulting from long pulse transmissions are not used for integration.

Abstract: A positive displacement air delivery system for an internal combustion engine having a multiple chamber positive displacement air pump and a control valve for directing the output of the air pump to either the engine's catalytic converter or to the engine's air intake for supercharging the engine. The control valve interconnects the individual input and output ports of the air pumps chamber in a predetermined arrangement for optimum efficiency of the pump under the various operational modes of the engine.

Abstract: A fluid level indicator is provided for a master cylinder to generate a signal in response to the fluid level reaching a predetermined level.

Abstract: A brake actuation assembly (10) wherein a front shell (50) of a booster mechanism (14) is attached to a stationary bulkhead (32) and the housing (58) of a master cylinder (12). On actuation of the booster mechanism (14) an output force is produced to operate the master cylinder (12). The operation of the master cylinder (12) develops a corresponding reaction force which is directly transferred into the stationary bulkhead (22) to substantially eliminate any axial deformation in the rear shell (20) of the booster mechanism (14).

Abstract: A thin, flat, elongated band (50) of flexible material having opposite ends and of roughened surfaces is slidably wrapped about itself several times and around a plug shell (20) such that one end is confined against the plug shell and the other end is connected by a tab (52) to a coupling nut (30), the coupling nut including on its inner wall a plurality of radial detents (42) sized to successively receive the tab (52) upon rotation of the coupling nut, rotation of the coupling nut (30) and threadable coupling with a receptacle shell (10) in a coupling direction drawing the shells (10, 20) together whereby cooperating flanges (36, 22) on the coupling nut and plug shell and thread flanks are tightly abutting, coupling rotation tending to unwrap the band (50) so that it will slide freely about the plug shell, uncoupling rotation being resisted by the band tightly coiling so that it will not slide about the plug shell, increased external torque camming the tab (52) from its detent (42) and into the next detent,

Abstract: A wire spring (60) for a disc brake includes a coiled portion (62) with a pair of arms (64, 66) cooperating with the caliper via slots (70, 76) and with a friction element (24) via ends thereof (32, 34) in order to reduce rattle caused by the friction element while at the same time releasably attaching the friction element to the caliper assembly.

Abstract: A vibration adjustable spacer (10) is disclosed. In a preferred implementation spacers 10, 10', 10" are used to damp the vibrational resonance of a number of printed circuit boards (42, 44, 46) in an assembly (40). The spacer (10) has an adjustable snubbing member (30) which extends to abut an essentially stationary surface (7) when the board is accelerated in one direction and a pivotable member (22) operating such that retraction of the snubbing member is impeded when the board is accelerated in the opposite direction.

Abstract: Mechanism for cleaning and drying compressed gas (10) includes a housing (12) having an open end closed by an end cover (14). A desiccant canister (16) is mounted on a plate (24) which is clamped between the end cover (14) and the housing (12) so that the canister (16) is received within the housing (12). A circuitous passage (78) communicates an inlet port (76) with a sump cavity (68) which is communicated with the canister (16). Heat is transferred from the gas to the walls of the passage (78) as the gas passes therethrough. The passage (78) cants toward the sump (68) so that moisture tends to drain into the latter. A dump valve (110) periodically communicates the sump cavity (68) with atmosphere to thereby regenerate the desiccant in the canister (16) and to void the contaminants from the sump cavity (68).

Abstract: A retainer 226 for holding a control valve 656 of a servomotor 42 in a bore 90 of a hub 78. The hub 78 which is attached to a movable wall 56 has first 92 and second 96 passages that connect the bore to first 86 and second 88 chambers in the servomotor 42. The retainer 226 limits the movement of the control valve 656 in the bore 90 to establish a full release position whereby the pressure of the fluid in the first 86 and second 88 chambers equalize. In response to an input force, the control valve 656 moves to an actuation position where fluid under pressure is communicated to the second chamber 88 to create a pressure differential across the movable wall 56. The pressure differential acts on the movable wall 56 to develop an output force corresponding to the input force. On termination of the input force, the control valve 656 moves to the full release position where the fluid pressure equalization occurs.

A planetary gearset (64) drivingly connects the driving member (12) and driven member (16) to drive the driven member (16) at a speed lower than that of the driven member (12) when the electromagnetic actuator (46) is energized. When the electromagnetic actuator (46) is not energized, a clutching member (22) engages the driven member (16) to cause the latter to be driven at the same speed as that of the driving member (12).
