Patent DE-3739475-A1 (DE)
Title: Embossing tool
Inventor: MAAG RUDOLF
IPC: B44B5/00
Filed: 1987-11-21
Abstract: Previous embossing tools consist of rollers arranged on an axle, on the outside of which rollers the desired markings are made. The embossing force therefore has to be borne by the axle, which results in extremely difficult execution, which is thus slow and also difficult to operate. A lightweight design which also guarantees rapid marking is achieved by means of the invention, consisting of a guide piece in which embossing pins are arranged in a longitudinally displaceable manner, these being capable of being actuated by controllable pressure pieces which can be inserted between an embossing plate and the heads of the embossing pins. <IMAGE>

Abstract: A pressure medium control device serves to control a servomotor (1) of a motor vehicle steering system. The servomotor (1) can be adjusted either by a hydrostatic steering system (2) or by an automatic steering device (4). In its neutral position, a steering valve (6) of the hydrostatic steering system (2) shuts off all the ports, apart from a control port (control line 12) for the current-dividing valve (8). In the neutral position of the hydrostatic steering system (2) the control connection connects the control line (12) to a return line (19) which is connected to the line (9) leading to the automatic steering device (4). The steering valve (2) has integrated restrictors (16) which act in the steering positions and produce a difference in pressure for the adjustment of a current-dividing valve (8). The line (9) which is connected to the automatic steering device (4) branches off from a working line (10) which leads to the steering valve (6). The line (9) contains a solenoid valve (41) with a blocking position and a throttled flow position. The solenoid valve (41) can be switched over into its flow position together with discharge blocking valves (32 to 33) contained in the automatic steering device (4).

Patent DE-3814466-A1 (DE)
Inventor: LYSEN HEINRICH ING GRAD
IPC: G01S5/16
Filed: 1988-04-28
Abstract: A device for finding the relative position of the reference axis (BA) of an object relative to the reference beam (Rp) of electromagnetic radiation, in particular a laser beam, has a static radiation transmitter (S) and, on the side of the object, a dividing mirror (22) and two position detectors (23, 25). Said dividing mirror creates a subbeam (Rp') derived from the reference beam. The reference beam passing through the dividing mirror in a straight line impacts on one of the position detectors, the subbeam impacting on the other one. The position detectors emit electrical signals on the basis of which the position of the reference axis can be determined by means of a computer. Known devices of this kind are very bulky. This is no longer the case in the device according to said invention because of its special beam guide configuration and the special additional optical means it uses. Measuring possibilities can be further improved by emitting a second reference beam (Rs).

Abstract: PCT No. PCT/CH89/00178 Sec. 371 Date Mar. 21, 1990 Sec. 102(e) Date Mar. 21, 1990 PCT Filed Sep. 29, 1989 PCT Pub. No. WO90/03876 PCT Pub. Date Apr. 19, 1990.The method is used to process a synthetic moulding compound which crystallizes within a specific temperature range. In order to prevent milkiness in the blank to be produced, the moulding compound is chilled. The method prevents such milkiness, at least in the gate area of the blank, by keeping all of the moulding compound, during the operating cycle, as far as the gate area, at a temperature which is above the temperature TCC below which the moulding compound begins to crystallize. A gate system, which may be used to carry out the method, uses, in the interior of the injection nozzle, a strongly heat conducting nozzle core, a strongly heat conducting area in the immediate vicinity of the gate opening, and a gap for heat insulation of the nozzle tip, the nozzle core and the moulded body.

Title: Self-locking differential with actuating-force multiplication levers
Inventor: KELLER WALTER
IPC: F16H48/30
Filed: 1988-11-25
Abstract: This self-locking differential (1) is provided with a frictional connection device which can be actuated by way of multiplication levers (8) and in which the multiplication levers (8) are arranged unsprung axially in front of its pressure ring (7) and parallel thereto in an annular gap (13) in such a way that the said gap takes up approximately only the outside dimensions of the pressure ring (7). The free space (18) required in front of the levers (8) on the slip-ring side for the tilting movements also need only be approximately the depth for the motional play of the levers (18) and this only at maximum deflection. The forward support (9) for the levers (8), that adjacent to the pressure ring (7), is provided in the edge region in the vicinity of the central effective friction-surface diameter and only about one and a half to two times the lever thickness away from the rearward, rigid support (10), giving a large lever-arm difference and high force multiplication. The narrow sides of the flexurally stiff levers (8) are supported rigidly in the axial direction against an internal collar of the case (2) and, at the other end, are supported in axially displaceable fashion against a slip ring (12) displaceable by auxiliary force. This construction is short and compact and permits both a favourable action on the friction surface and favourable distribution of bearing loads with direct linear force transmission without the need for higher deformation energy requiring the expenditure of auxiliary force and without additional outlay in terms of material or space for springs or joints and their travels when actuated. <IMAGE>
