Abstract: A conveyor device for transporting workpieces, particularly workpiece carriers (80) has two parallel transport ways (1, 2) and a transverse conveyor (3) arranged between the latter. The support frame of the transverse conveyor (3) has an immovably arranged central section (90) and two end sections (100, 110) mounted pivotably on the latter. Each of these end sections (100,110) intersects an inner roller system (60 or 70) of a transport way (1 or 2) and bridges the space between the roller system (60 or 70) and an outer web belt (4 or 5) of the transport ways (1 or 2). A lift device (410 or 420) by which the end sections (100, 110) are pivotable into a plurality of different vertical positions relative to the transport ways (1, 2) is associated with each of the two end sections (100, 110).

Abstract: In a headlight of a motor vehicle, having a housing and a diffusing lens enclosing with the housing an interior of the headlight, the interior is vented by means of a conduit exposed to air streams caused by travelling of the motor vehicle. The conduit is formed as an integrated part of the diffusing lens made of plastics.

Abstract: A control arrangement for a hydraulic motor has an adjustable pressure medium supply device with a container, an unblockable check valve with a control connection, a plurality of chambers including a supply chamber, a motor chamber, first and second return chambers, and a control chamber, a control slider displaceable relative to the chambers, wherein a control conduit extends from the supply device and leads to the control chamber, a first pressure control member is arranged on the control slider so that in a lowered position of the latter the first pressure controlling member is located between the control chamber and the second return chamber and the control slider in its raised position blocks the control chamber, and a second pressure controlling member located between the control chamber and the motor chamber and opening into the latter.

Abstract: An element firmly connected with the drive shaft of an injection pump is locked in a predetermined rotary position, corresponding to the supply onset, by a locking device before the mounting of the injection pump to the associated internal combustion engine, the locking being effected by means of a holding bolt embodied as a reversible part. The holding bolt, locked by a fastening means in a reception bore, engages a transverse groove on the end face, in a first mounting position, via a protrusion on the element firmly connected with the drive shaft, and thus establishes a form-locking connection which keeps the drive shaft in the predetermined rotary position. In a second mounting position of the holding bolt, where the transverse groove points outward, the rotary movement of the drive shaft is unhindered.

Abstract: A gear positive displacement machine has a housing, two gear members, and two bearing members supporting the latter. A gap is formed between an inner wall of the housing and a respective one of the bearing member, the gap increasing in two opposite axial directions. It may start from a central transverse plane of the bearing member. The gap may be formed by a convex peripheral surface of the bearing member or by a convex inner wall of the housing.

Abstract: A gear positive displacement machine has two meshing gear members each having two axially opposite shafts, two pairs of bearing members each of which pairs bears one shaft of both gear members, at least one sealing member at one axial end of the gear members, and a supporting element reinforcing this sealing member. The supporting element has a U-shaped cross-section with two arms and a bead at a free end of each arm. The sealing member is inserted by its base side in the supporting member, and the beads of the arms of the latter engage in two grooves formed in the supporting member.

Abstract: A piston rod connected at one end to a piston slidably arranged in a cylinder projects with its other end through an opening in an end wall of the cylinder beyond the latter and a fork-shaped member is connected by a friction weld, that is without adding welding material or external heat, to the other end of the piston rod.

Abstract: An electromagnetic 3-way valve arrangement having two valves, each controlled by a separate armature of a single coil solenoid, is described. The top end of each armature has a self-aligning closing element, and the two armatures are held apart by springs acting against an intermediate member, which also contains the valve seat for the lower armature. When deenergized, these springs act against the armatures to close the upper valve and open the lower valve. When the solenoid coil is partially energized, it moves the lower armature upward to close the lower valve also. When the solenoid coil is fully energized, it moves the upper armature downward to open the upper valve. If desired, the armature can be disposed within the solenoid so that the upper armature is operated at partial energization, and the lower armature at full energization of the solenoid coil.
