Abstract: A vehicle suspension for motor vehicles in which a semi-active suspension is combined with an active suspension to make a novel suspension. The pump power of the active suspension, however, is designed merely for overcoming the necessary frictional forces. The advantage is that for such a vehicle suspension, a lightweight pump of low power, small diameter lines, and a small 4/3-way magnetic valve requiring little current can be used.

Abstract: An apparatus for determining the flow rate of a flowing medium having a substrate as a carrier and a resistor arrangement disposed on the substrate which among other elements includes a layer-like measuring resistor (R.sub.H) as well as a likewise layer-like heating resistor (R.sub.S), the heating output of which is regulated such that the measuring resistor (R.sub.H) has a constant temperature, the heating output of the heating resistor (R.sub.S) being a standard for the flow rate of the flowing medium. The surface area of (R.sub.S) is greater than the surface area of (R.sub.H) and extends farther toward a fastening of the substrate, in order to prevent a flow of heat out of the vicinity of the measuring resistor (R.sub.H). The measuring resistor (R.sub.H) and the heating resistor (R.sub.S) are located on the downstream portion of the substrate, on a lip set off by a slit. With this disposition of the measuring resistor (R.sub.H), soiling of the substrate affects the measurement result only slightly.

Furthermore, at least one load cross-piece is arranged in the crane bridge parallel to the pallet boxes in such a manner that it can be removed by the carrying devices, which load cross-piece is of the same length as the pallet boxes and is provided on its end faces with supports in a manner corresponding to the pallet boxes.

Abstract: A brake system which has a brake booster, a brake pedal which acts via a travel simulator device upon the brake booster, at least one anti-skid valve, two sensors (S.sub.p, S.sub.I) and a pulse emitter. One of the sensors measures braking pressures. The other sensor (S.sub.I) measures the displacement distances of a piston, which is displaced in the brake booster to effect braking. A comparator connected to the sensors (S.sub.p, S.sub.I) switches the pulse emitter on whenever the piston travels a longer displacement distance than is permissible at a predetermined braking pressure. The pulse emitter controls the anti-skid valve such that a driver who actuates the brake system perceives changes in braking acceleration, and these changes are intended to emphatically cause him to seek a repair facility.

Abstract: A hydraulic vehicle brake system having a brake booster integrated in a housing and having a master cylinder unit comprising at least two master cylinder pistons with corresponding pressure chambers for at least two separate brake circuits into which an anti-skid system is incorporated, and in which the brake booster and the anti-skid system communicate with a hydraulic energy supply system. The master cylinder pistons are to be disposed in the housing in an axially parallel location, radially opposite of and axially parallel with a restoring piston to be actuated by the anti-skid system. To this end, the master cylinder pistons are connected in the housing with a bushing that is axially displaceable by elements of the brake booster, and this bushing also acts upon the restoring piston.

Abstract: An anti-skid brake system has a first brake circuit (I) terminating at two wheel brakes and connected to a dual-circuit master cylinder, a brake pressure modulation valve assembly and a recirculating pump. In an anti-skid situation, in order to reduce brake pressure, fluid is withdrawn from the two wheel brakes by the brake pressure modulation valve assembly and then returned to the master cylinder by the recirculating pump. Associated with a second brake circuit (I), which is likewise connected to the master cylinder and which terminates at two other wheel brakes, is a floating piston assembly connected to the first brake circuit (I). In an anti-skid situation, a pressure reduction, which is performed in the first brake circuit (I) by the brake pressure modulation valve assembly brings about a pressure reduction in the second brake circuit (II), via the floating piston assembly.

Abstract: A method for orienting a feeler of an apparatus for testing gear flank profiles and flank lines of gear wheels is disclosed, in which the feeler is successively inserted, in two adjacent positions, into an accurately made gap element located on the gear wheel and from the thus ascertained values the location of the point of intersection of the wheel axis with the measuring plane is ascertained, optionally by means of a computer. The gap element, embodied as an orientation gap mounted on the gear wheel, that is approached by the feeler in the first position is rotated with the gear wheel into a second position, and there the feeler, embodied solely by the measuring feeler, is inserted into the same orientation gap. Therefore measurements are made by use of the same orientation gap and the same feeler at two different locations.

Abstract: This invention provides a method of preventing loss of muddy water used in boring a hole in the ground by a drill bit or the like with the muddy water introduced into the hole to stabilize hole walls and to remove slime resulting from the boring. When the muddy water is getting lost to the soil, a chemical liquid comprising an isocyanate compound or including an isocyanate compound as a main component is introduced along with a fibrous filler to a depth of the hole. The position from which the muddy water is leaking is filled with the fibrous filler and is sealed with a cured product of the chemical liquid.

Abstract: A fuel injection pump for internal combustion engines having a plurality of pump elements 2, 3 disposed in a line, the injection quantity control of which is effected via a control slide 9 that is axially displaceable on the pump piston 9 and by controlling a relief conduit 22-25 of the pump work chamber 18, the control slides 9 being surrounded by partial suction chambers 8 that discharge into a main suction chamber 10 receiving a torque shaft 12 for axially actuating the control slides 9. These partial suction chambers 8 each have a separate partial inflow conduit 39 of defined length and cross section, which communicates with an inflow conduit 33, so that the same volumetric flow is metered to each partial suction chamber in the manner of quantity division, while the main suction chamber 10 is retained and the torque shaft 12 is disposed in it.

Abstract: A fuel injection pump is proposed in which the fuel supply quantity supplied to the injection location is determined by metering the quantity of fuel aspirated. The metering of the aspirated quantities is effected with the aid of at least one magnetic valve which is located in the fuel supply line leading to the fuel injection pump and with the aid of a control edge moved in synchronism with the rotation of the fuel injection pump, which controls the communication between the fuel supply line and the pump work chamber in series with the magnetic valve. The opening times of the two control locations are each longer than the maximum metering time, the overlapping time of the two control times determining the opening time of the communication between the fuel supply and the pump work chamber. The metering time is thus determined on the one hand by the switching time of the control edge moved in synchronism with the rpm and the other by a switching process of the magnetic valve.

Abstract: A device for advancing rod-shaped material in a cutting machine, in which ring the cutting operation the material is held by at least one pair of clamping jaws that are arranged in front of the cutting plane in the material advance direction and by a pair of advancing jaws which are arranged after the cutting plane and can be displaced in the material advance direction, of which at least one advancing jaw can be moved transversely to the material advance direction for the purpose of clamping the material and by means of which the workpiece material can be displaced by an amount corresponding to the portion to be cut off and by means of which the severed material can be removed. The arrangement is such that the transversely movable advancing jaw can be displaced beyond the other advancing jaw and that the other advancing jaw can be moved out the corresponding lateral displacement path of the severed material for disposal of the cut piece of material.

Abstract: A valve assembly for an anti-skid brake system has at least two valves disposed parallel to one another. Both valves are embodied in the manner of check valves having closing springs. To open the valves, there is an armature displaceable by an electromagnet; the armature opens the first valve automatically via a rigid opening tappet and opens the second valve, via another opening tappet and a spring associated with it, only when a pressure urging the second valve in the closing direction does not exceed a preselected pressure difference relative to an armature chamber. This has the advantage that despite the high pressure drop, the quantity of pressure fluid per unit of time that flows through the valve assembly does not exceed a preselected threashold value in the anti-skid regulation situation; on the other hand, without anti-skid operation, a rapid buildup of brake pressure is possible by furnishing a larger flow cross section.

Abstract: A lightweight ball-and-socket joint that is for instance capable of being assembled by a robot. The ball-and-socket joint has a ball head, a CIRCLIP and an outer structural part forming a socket, in which there is a circumferential groove the bottom of which forms a support face for the circlip. The support face is substantially defined by a hollow cone and surrounds the CIRCLIP like a jacket, and a flare angle of the support face opens toward the center of the ball head. The CIRCLIP presses with radial bias against the support face and therefore migrates in the direction of its largest diameter and hence toward the center of the ball head until it rests thereon.
