Abstract: The invention relates to a clutch device for a motor vehicle with a clutch pedal (4) which is connected to a master cylinder-piston unit (1, 2), with a clutch lever (11) which is connected to a slave cylinder-piston unit (8, 10), with a connecting line (13, 13a) between the master cylinder-piston unit (1, 2) and the slave cylinder-piston unit (8, 10), with a free wheel cylinder-piston unit (16, 17) in the connecting line (13, 13a), the free wheel piston (17) being connectable to a control valve (20, 21, 22), to a pressure line (19) and a discharge line (18). The control valve (20, 21, 22) can be triggered by way of a control circuit with an accelerator pedal switch (reversing switch 26, 27). The voltage supply (+) of the control circuit leads by way of a holding circuit (relay switch 32 with magnets 33, 34) which is brought by a manual pushbutton switch (38) into the ON position and by a clutch pedal switch (29), which switches when the clutch pedal is depressed, into the OFF position. As a result, when running with the voltage supply (+) switched on and released accelerator pedal (25) (free wheel operation), the entire control circuit for the free wheel operation is switched off when the clutch pedal (4) is depressed. In danger situations or when activating the engine brake, actuation of the clutch pedal (4) corresponds to the instinctive behaviour of a driver, as a result of which false reactions ...

Title: Vacuum clamping table for clamping workpieces
Inventor: JENKNER ERWIN
IPC: B25B11/00
Filed: 1983-05-09
Abstract: In a vacuum clamping table, suction heads are provided for clamping plate-shaped workpieces, which suction heads are arranged under corresponding table openings and can be lifted essentially up to the level of the workpiece-resting plane. To this end, the suction heads sit in groups on strip-shaped supports which are arranged under the table and for clamping a workpiece can be placed against the underside of the table by means of an adjusting device. Supporting forces on the top and underside of the table thereby come into effect in such a way as to be directed towards one another. The table construction can accordingly be of favourable design.

Title: Container with open top
Inventor: PALMASON JON ARNAR
IPC: B65D21/02
Filed: 1983-05-24
Abstract: A container with an open top has a bottom (10) and two upright side walls (11, 12) and end walls (13, 14) and is particularly suitable for receiving fish, vegetables and other perishable products. A slot (15, 16) which is open at the top is formed in at least one of the side walls (11, 12), specifically in the region of the inner surface of one of the end walls (13, 14), and in the other end wall, specifically in the region of the inner surface of the other side wall. Identical containers can be stacked in the filled state. When the containers are empty, two containers can be linked together in such a way that they mainly take up only the space of a single container because the slot formed in one of the containers can accommodate the side wall and the end wall of the other container. <IMAGE>

Title: Mounting case for doors, windows or the like for use with unequal wall thicknesses
IPC: E06B1/20
Filed: 1983-06-30
Abstract: In a two-part mounting case for doors, windows or the like, in which a door stop frame and a case engage in one another in a partially overlapping manner for the purpose of adaptation to different wall thicknesses, the overlapping region is shaped in such a manner that the door stop frame is designed as a U-shaped receptacle, into which a U-shaped counterpiece of the case is introduced. This U-shaped counterpiece has grooves in the longitudinal direction, into which during assembly the connection screw penetrates between door stop frame and case. Preboring of the case is thus avoided, as a result of which a better positive fit between door stop frame and case can be achieved. <IMAGE>

Title: Device for placing components in the form of small plates and/or rods on a belt
Inventor: SILLNER GEORG
IPC: B65B15/04
Filed: 1983-11-26
Abstract: The invention relates to a device for separating and arranging plate-like and/or rod-like components, especially electrical components, from a disordered pile into prepared receptacles of a carrying element which is, for example, in the form of a belt. The components are in each case transferred at a feeding position, in which they wait in the form of a disordered pile, to at least one groove of a circulating transport element and are then arranged in the groove in such a way that the components remaining in the groove are connected to one another in a predetermined position to form a continuous row. At a delivery position, the carrying element is led past the transport element in such a way that the receptacle provided in the carrying element is congruent with a component located in the groove of the transport element, so that this component can then be transferred from the groove to the receptacle of the carrying element.
Patent DE-3345740-A1 (DE)
Title: Rope winch
Inventor: BECHMANN PETER
IPC: B66D1/74
Filed: 1983-12-17
Abstract: The rope winch is provided with a driven rope drum as well as with a clamping disc arranged coaxially to it and driven in synchronism with it. The rope drum has a friction surface lying at an angle to the drum axis. Allocated to the friction surface is a friction mating surface running at a corresponding angle and rotating with the clamping disc. When a load is being fetched, the sectional lengths of the load rope which are wound up on the rope drum produce an axially directed force component. The friction surfaces are thereby displaced relative to one another as a function of the load to be fetched, so that a load-dependent clamping force is exerted on the load rope.

Title: Counter attachment having a lifting fitting for the pivoting movement of a plate about a horizontal axis
Inventor: STENEMANN BRUNO
IPC: F25D23/02
Filed: 1984-03-26
Abstract: In the sales counter according to the main patent, having plates which can be pivoted about a horizontal axis, a bearing block is used which is to be fastened to the upper front end of the support and consists of a longitudinal profile of continuous uniform shape in the direction of the width and is bounded at both ends by longitudinal side surfaces at which transverse bores open out which serve for receiving the pivoting axle pin and a further pin intended for linking a gas pressure spring. In order also to be able to build a counter of a different type with few, space-saving components, it is proposed to construct the bearing blocks to have a different block width relative to one another. It is then irrelevant whether the bearing blocks are arranged at the end sides of the counter or at the centre of the counter and how thick the plate is because these factors can be compensated by a width dimension of the bearing blocks.

Filed: 1984-04-05
Abstract: The invention relates to a face end system with a road head following the face while using a face/roadway conveyor, equipped with a rolling curve, and with plough winning at the face. The plough guide, attached on the working-face side to the face/roadway conveyor, is extended at the face end right into the roadway area. Correspondingly, a guide leading across the rolling curve is provided on the goaf side of the face/roadway conveyor for the driving machine, by means of which the roadway face is worked to a predetermined thickness of, for example, about 1.6 to 2.0 m. At the set-back road head, the roadway is then brushed down to the final cross-section. Standing behind the rolling curve are two hydraulic support assemblies of special construction. These support assemblies have an especially large overall width so that the face/roadway conveyor can be passed through one support assembly, while the other support assembly forms a passage opening to be used as a travel way. Furthermore, protective hoods are conveniently coupled to the support assemblies.
