Abstract: A quick connector adapted for locking engagement with a male member includes a cylindrical body portion open at one end for receiving the male member and a through passage communicating the open end with a conduit receiving adapter at an opposite end. A valve member is located in the passage and is displaceable from a closed position to an open position to establish open communication therethrough in response to engagement of the body portion and male member. Relatively displaceable, at least partially radially coextensive seats are provided to effect axial engagement with the seal in the closed position.

Abstract: The invention is related to an electromagnetic valve including a magnet armature enclosed by a valve dome. The armature performs a stroke movement depending on a magnet coil being energized by the supply of electric current to magnetize a magnet core. A valve needle is slidably disposed in the magnetic armature and is partly encircled by the magnet core. The valve needle interacts with a valve seat which is fixed within a valve housing. A non-ferro magnetic anti-stick disc is disposed between the magnet core and the magnet armature.

Abstract: An IC card is provided which can be constructed at low cost and which allows adjustment of circuit board position. The circuit board (32, FIG. 2) has forward and rearward end portions (34, 36) which are mounted directly on forward and rearward connectors (12, 14), without a separate frame to mechanically hold them together. A cover (60) with upper and lower parts (66, 68), is mechanically mounted to the connectors and is coupled to the circuit board only in an electrical ground. Each connector is mounted to a circuit board end by pegs (90, 92) of support parts (91, 93 and 95, 97) that lie on laterally opposite sides of the row of connector contacts (46), with each peg being received in a hole (100, 102) of the circuit board and with the circuit board resting on a board-receiving surface (150, FIG. 4) lying adjacent to the peg. The pegs can have two or more steps (140, 142, 144) to hold the circuit board at different heights.

Abstract: One end of a dual-ended housing is closed off by a plug formed of a first constituent which is a water-soluble material and a second constituent which is a thermosetting resin and forms a readily-frangible structure in the plug. An electrical switch which has an actuating plunger is set, in the housing against the plug, so that the latter holds the plunger depressed/retracted. Moisture expands the water-soluble material which, in turn, destroys the plug integrity and, subsequently, the plug is so weakened that the plunger breaks through the frangible structure to actuate the switch.

Abstract: An energy absorbing apparatus includes first and second telescopingly arranged members. A non-deformable ring is mounted on one end of one of the members and engages a plurality of projections extending from the side wall of the other member. The projections extend longitudinally along the other member and are provided in various lengths, widths, heights and numbers to provide selective force versus displacement characteristics during the telescoping collapse of the first and second members with respect to each other. Preferably, the first and second members form a steering column housing for a vehicle steering apparatus.

Abstract: A circuit configuration for detecting wheel sensor malfunctions includes circuits which process and analyze the sensor signals (s.sub.1 to s.sub.4), which ascertain the speed (v.sub.Rmax, v.sub.Rmin), deceleration and acceleration (a.sub.R) of the individual wheels and which compare these values with one another and compare them with predetermined threshold values (a.sub.0, v.sub.0, v.sub.1, -a.sub.1). Upon the detection of signals or combinations of signals typical of a sensor malfunction, the control will be disconnected after a predetermined period of time (T, T1+T2). When the measured acceleration values (a.sub.R) are below an overspeed threshold (a.sub.0) and the speed at any one of the remaining wheels is below a bottom speed threshold (v.sub.0), the control will be disconnected as soon as the speed of a wheel (v.sub.Rmax) exceeds a top speed threshold (v.sub.1). A time monitoring function is started in the presence of a measured acceleration value (a.sub.R) which is above the overspeed threshold (a.

Abstract: For the reduction of disadvantageous effects of engine stall torques on the braking behavior of a vehicle which is equipped with a brake unit having an anti-lock control system, the brake slip of the driven wheels is monitored independently of any actuation of the brake. In the event of a rotational behavior of the driven wheels which is typical of the effect of engine stall torques, in particular in the event of a brake slip at the driven wheels exceeding a limit value, brake pressure existing in the wheel brakes of the driven wheels is maintained constant or reduced, or, if the braking action has not yet commenced, the supply of brake pressure into the wheel brakes of the driven wheels is prevented.

Abstract: An IC card is described which has a housing that is of low cost and which provides very good shielding against ESD/EMI (electrostatic discharge and electromagnetic interference), while securely holding a circuit board assembly and providing good contact with a ground conductor of the board. The housing comprises lower and upper housing halves (22, 24, FIG. 2), each molded of an electrically conductive polymer. The lower housing, half includes a bottom cover portion (90) and a pair of upstanding flanges (92, 94) that each forms part of a side of the housing. The upper housing half forms a top cover portion (100) and a pair of downwardly extending flanges (102, 104). The circuit board has a ground conductor (70) at its periphery which is trapped between the upper and lower housing halves to securely hold the circuit board in place and to electrically ground its ground conductor. Each housing half has platform parts (114, 116, 120, 122) that engage corresponding surfaces of the circuit board.

Abstract: A fan motor support, for use in combination with a motor vehicle radiator of the type having a U-shaped channel extending along an upper side of the radiator, having a motor mounting portion, a support structure and a claw portion. The motor mounting portion has a motor opening therethrough. The support structure is configured to extend across a portion of a rear surface of the radiator. The claw portion extends from the support structure and has a first member configured to reside in the U-shaped channel.

Abstract: First and second arrays of easily mated coaxial connectors are provided, which are of compact construction to enable efficient transmission of very high frequencies and in a compact arrangement. The outer conductor (22, FIG. 5) of a first connector (1) includes a male outer contact part (44) which is received in a female outer contact part (46) of the second connector, which leaves a step (70) where the inside surface of the male contact part is smaller than that of the adjacent female contact part, thereby creating a capacitive discontinuity. The front ends (74, 76) of the dielectric members (24, 34) of the first and second connectors are slightly axially spaced apart to leave a gap (72) between them. The gap produces an inductance that cancels the effect of the capacitance created by the step, to minimize insertion and return losses. The fact that the compensating gap and step are present avoids the need for a butt interface of the outer conductors.

Abstract: The present invention relates to a piston with a central valve, in particular for hydraulic boosters, the valve case (6) which is composed of a supporting insert (8) radially embraced by a valve seat (7). It is disadvantageous in some valve cases that sometimes the positive coupling between the two elements in axial direction is not sufficient. The present invention provides a remedy to this problem by using undercuts behind which the valve seat engages the supporting insert in both directions. In an advantageous improvement, the valve insert is of symmetrical design, and a sealing projection is shaped at the valve seat. The guidance of the valve tappet (19) is performed within the piston (1).

Abstract: A method of manufacturing a steering column stalk switch apparatus includes the steps of fixedly engaging a hub attached to an elongated shaft to one end of a hollow housing having apertures formed at opposite ends, movably mounting a button in one of the apertures in the housing, the button being movable between first and second positions and biased to the first position, mounting a first electrical contactor having first electrical contacts thereon in the button, movably mounting a second electrical contactor with second electrical contacts thereon in the housing, the first and second electrical contacts being co-planarly aligned, mounting a circuit board with conductive tracings in the housing such that the first and second contacts slidably engage the conductive tracings and complete circuits therebetween depending upon the position of the first and second electrical contacts, mounting the second electrical contactor on a movable carrier in the housing, biasingly mounting a detent paw on the carrier, alig

Abstract: A cast-aluminum floating caliper of a floating-caliper spot-type disc brake is reinforced by means of reinforcing elements of a high-tensile material. In accordance with one embodiment of this invention the floating caliper is provided with recesses in an area adjacent the brake disc and the brake shoes. Bolts extend through the recesses in the direct vicinity of the radially outside brake disc edge. Commercially available steel bolts preferably are used. These measures optimize the floating caliper weight, stiffness and manufacturing cost.

Abstract: A stuffer pin for mounting seals and a retainer element in a quick connector used with fluid conduits. The stuffer pin includes an integral shaft, an enlarged stop and a handle. Annular seal mounting portions are formed on the shaft for releasibly supporting seal elements. A ridge is formed on the shaft for releasibly engaging and mounting a retainer on the shaft. Resilient arms extend axially from an end of the shaft and have a larger nominal outer diameter than the diameter of the shaft to retain the seal elements on the shaft prior to insertion into a bore in a fluid carrying member. The resilient arms are bent radially inward when contacting a stepped bore in the fluid carrying member to enable release of the seals and retainer elements during withdrawal of the stuffer pin from the bore.

Abstract: A brake unit for automotive vehicles with electric drive is configured in the shape of a multiple-circuit compound system consisting of hydraulic friction brakes of brake circuits (I, I', I", III, III', III") and of an electroregenerative brake system (circuit II, II', II"). In a vehicle with a driven and a non-driven axle, three brake circuits exist, one brake circuit of which (I, I', I") is comprised of a pedal-actuated hydraulic brake pressure master unit (2) and of friction brakes (3, 4) acting upon the non-driven wheels. The second brake circuit (II, II', II") which represents an electroregenerative brake system is directly or indirectly coupled to the brake pedal and acts upon the driven wheels. The third brake circuit (III, III', III") which is comprised of friction brakes (10, 11) also acts upon the driven wheels. The actuation of the wheel brakes (10, 11) is connected to the second and third brake circuits.

Abstract: The invention provides a telephone network connector (10, FIG. 8) with a rear portion (47) that holds a cartridge (56) which enables connections directly to ground and through a circuit component to ground. The cartridge lies within an electrically grounded metal shell (32), that, in turn, lies within a molded dielectric container (48). The cartridge has a grounded contact element (74, FIG. 2) which has threaded part (78) extending through a threaded hole (80) in the grounded shell. The cartridge also has a nongrounded contact element (76) which projects through a bushing part (92) of the dielectric container, which isolates the nongrounded contact from the walls of a hole (91) in the metal shell. The molded dielectric container forms a front connect tube (51, FIG. 8) and a pair of side tubes (52, 53).

Abstract: An anti-lock hydraulic brake system is disclosed with a flow control valve in the brake line. To prevent the flow control valve from performing its control function during a normal braking operation, a retaining piston works in conjunction with a spring such that the retaining spring bears against a piston of the flow control valve and retains the flow control valve piston in its initial position during normal braking operation. The retaining piston also serves as a valve closure member for a valve in the return line.
