Abstract: A method of manufacturing a mop and in particular a mop head. The mop head is made from a rectangular piece of open cell sponge, a cylindrical core and a wringer assembly. A groove is cut along a longitudinal axis of the sponge while the external rectangular corners are also removed along the longitudinal axis to define a member with substantially five equal longitudinal surfaces. An adhesive is placed in the groove to join the cylindrical core with the open cell sponge. The wringer assembly has a strap which retains a roller which is attached to the cylindrical core to locate the roller at a fixed distance from the cylindrical core. A handle which is perpendicularly attached to the center of the cylindrical core has a tapered surface which provides a stop for the roller in the rest position.

Abstract: The hydraulic brake booster (12) of the present invention comprises a full power hydraulic brake booster (12) that provides false travel during full power operation and improved pedal feel during manual operation. The booster (10) has a housing (24) with a slidable sleeve assembly (60) therein, the assembly (60) housing a sleeve member (98) which is displaced by accumulator fluid pressure against a collet housing (78) and a moveable collet member (79) located about an input member (94). The sleeve member (98) displaces the moveable collet member (79) against a resilient member (77) when the sleeve member (98) is displaced by hydraulic fluid pressure from the accumulator (14).

Abstract: The integrated adaptive braking and traction control system assembly (10) comprises an elongated body (12) having a bore (16) with a master cylinder mechanism (18) disposed therein. The body (12) includes a plurality of valve devices (26) for adaptive braking and traction control, a plurality of passages which connect the master cylinder mechanism (18) with the valve devices (26) and selected valve devices with other selected valve devices, a four-channel pump mechanism (90) for communicating fluid pressure toward associated wheel brakes (52, 62, 72, 82) of the vehicle, displacement chambers (42A, 42B, 42C, 42D) with displacement pistons (43) disposed therein, and a reservoir (40) which communicates with the master cylinder mechanism (40) and adaptive braking and traction control systems.

Abstract: The adaptive braking system (10, 110, 210, 310, 410) provides for the combination of a replenishment type anti-skid system having a full power hydraulic brake booster (12) with a pump (80) providing pressure via an accumulator (20) to the booster (12) and a pump-back system wherein the pump (80) communicates make-up pressure to the respective electrically actuated valve mechanisms (70, 170) and brakes when control of the brakes is effected by an electronic control mechanism (90) in response to an incipient skidding condition.

Abstract: An adaptive braking system (10, 210) for an automotive vehicle provides a three-channel split pump-back system which may be utilized with either two- or three-chamber master cylinders. The three-channel adaptive braking system (10, 210) includes a first braking circuit (40) for controlling one of the front wheel brakes (25), a second braking circuit (60) for controlling the other of the front wheel brakes (27), and a third braking circuit (80) for controlling the rear wheel brakes (24). A two-section pump (110) provides hydraulic pressure for the first and second braking circuits (40, 60) and for the third braking circuit (80). Alternatively, a three-section pump (310) can provide hydraulic pressure for each of the circuits (40, 60, 80).

Abstract: An integrated anti-lock braking system includes a master cylinder, a modulator valve assembly, an electric motor pump, a brake proportioning valve, and a differential pressure valve all integrated into a common assembly. Primary and secondary fluid passages defined within the housing are provided to communicate the various devices included within the assembly. The assembly includes a bracket engaging portion upon which a mounting bracket is provided to attach the assembly to the vehicle and which is capable of mounting the assembly to accommodate mounting at selected angles.

Abstract: The folded channel radial pump assembly (10) comprises a housing (12) having therein a stepped diameter bore (14) receiving a rotor (30). The rotor (30) is attached by way of a flexible coupling (50) with the output shaft (61) of an electric motor (60) attached to the housing (12). The rotor (30) includes one or more intake (26, 36) and exhaust (28, 38) ports, the ports (26, 28, 36, 38) being radially aligned and communicating with the stepped bore (14).

Abstract: The brake booster (12) includes a housing (30) with at least one piston (38) disposed in a bore (32) between a pressure chamber (42) and a work chamber (76). The piston (38) is disposed adjacent a valve housing (79) containing therein a valve assembly (80) and the valve assembly (80) is connected to an input assembly (72) at an end of the valve housing (79). The piston (38) includes a cam surface (78) engaged by a lever (17), the lever (17) abutting an actuator part (81) biased by a resilient spring (83) toward the lever (17). Actuation of the booster (12) effects a greater displacement of the piston (38) than the input assembly (72) and valve housing (79) because of the engagement of the lever with the cam surface (78) of the piston (38).

Abstract: The brake booster (12) includes a housing (30) with at least one piston (38) disposed in a bore (32) to separate a pressure chamber (42) from a work chamber (76). The piston (38) abuts a valve housing (79) containing therein a valve assembly (80) and the valve assembly (80) is connected to an input assembly (72) abutting the other end of the valve housing (79). The piston (38) and valve housing (79) are joined by connector (73) which permits limited movement of the piston (38) relative to the valve housing (79) before coupling the piston (38) and valve housing (79) together for joint movement.

Abstract: A hydraulic brake booster is disclosed which includes an integral accumulator to provide a fluid pressure source for emergency failsafe braking. The accumulator includes a bore defined within the booster housing, and a piston slidably mounted in the bore which divides the latter into a pair of fluid compartments between opposite ends of the piston and corresponding ends of the bore. One of the compartments is communicated to the booster inlet port so that the compartment is charged with fluid pressure whenever the pressure level at the inlet port is above some predetermined low value. In one embodiment of the invention, the other compartment is communicated to the fluid pressure reservoir, and a relief valve is carried within the piston which controls flow of fluid between the two compartments.

Abstract: A mop having a cylindrical core fixed to a handle by a fastener member. An absorbent material is attached to the cylindrical core. A U-shaped bracket has first and second legs attached to the cylindrical core by first and second pins. A roller is positioned a predetermined distance from the cylindrical core by third and fourth pins extending through the first and second legs. A resilient edge on the absorbent material holds the roller adjacent the handle. An input force applied to the U-shaped bracket moves the roller in an arc about the first and second pins to allow the roller to engage and compress the absorbent material and thereby remove material absorbed therein.

Abstract: A hydraulic brake booster includes a housing that defines a pressure chamber. A piston slidably mounted in a housing bore is responsive to increasing pressures in the pressure chamber to move relative to the housing to actuate a braking mechanism, such as a master cylinder. The piston carries a sealing ring to slidingly seal the piston to the housing bore and a shield to protect the surface of the housing bore from atmospheric contaminates during long periods, when the hydraulic booster is in a brake-release position. The shield releasably connects to the piston and telescopes into a piston cavity for compact assembly with the piston.
