Title: Membrane filter plate
Inventor: NEU WERNER DIPL ING DR ING
IPC: B01D25/21
Filed: 1984-07-02
Abstract: The object of creating a membrane of simple shape, which is simple to manufacture, which is simply and securely clamped in the base body and has a long operating life, can be achieved by means of a membrane filter plate which is composed of a plate-shaped base body having at least one recess which converts at its edge by means of a step and climbing surfaces into the plane forming the frame-like edge of the base body, and of at least one membrane which is smaller in its surface dimensions and which is composed of a resilient and flexible material, which membrane has a thickened edge having a surrounding rib which engages in a surrounding groove in the base body. The invention achieves this object by the membrane being planar in the state in which it is not subjected to pressure, by the groove in the base body being arranged in, or immediately adjacent to, the region of the inclined surface delimiting the recess, by the edge of the membrane forming an angled profile with the rib, by the outer edge of the membrane being wedge-shaped in cross-section and the side of the membrane edge resting agaisnt the base plate being larger than the side facing away from the base plate and by the edge of the recess outside the surrounding groove having a depth corresponding to the thickness of the membrane edge minus an elastic compression height, the part of the frame-like edge of the base body not covered by the membrane edge forming the sealing surface.

Title: Plug socket
Inventor: WILLNER JOSEF ING
IPC: H01R13/422
Filed: 1984-07-11
Abstract: In order to injection mould or draw in the electrically conductive part of plug sockets into the insulating body only small tolerances are permissible for the parts which are to be connected and, in addition, a considerable outlay is necessary for tools. In order to avoid this disadvantage, the metallic socket part is designed such that it can be pushed into the insulating body and, on its outer circumference, has a cone (3) whose cone surface points in the insertion direction. In the insulating body, there is a recess (4) into which the cone (3) latches when the metallic part is pushed into the insulating body. The field of application of the invention is sockets for plug connections. <IMAGE>

Title: Joining machine for the automatic production of multi-part workpieces from leather or plastic
Inventor: GROSSMANN PETER
IPC: B21D43/18
Filed: 1984-08-25
Abstract: Using this machine the workpiece is adhesively bonded together. This work was hitherto very time-consuming since the inner parts had to be placed individually by hand onto the outer part. In the machine according to the invention the individual parts provided with adhesive are automatically sucked from a deposition point, individually transferred to the workplace in the desired sequence, placed one above the other, heated, pressed together and thereby adhesively bonded. This machine (Fig. 2) has a base plate 3 for fastening a vertical post 2 which supports a U-shaped frame 1, a horizontally operating transport device 5 in a box 4 with suction pads 6, 7 for picking up and transporting the parts to be bonded, an upper tool 11 and a lower tool 12 in the frame 1, pressing cylinders 13 and 14 for downward and upward movement of the upper tool 11 and a switch box 15 on the frame 1 to house the electronically programmed control and switching circuits for the preset execution of the individual work steps and for the safety measures to indicate disturbances and faults. <IMAGE>

Patent DE-3442862-A1 (DE)
Title: Crystal mechanism, especially for wristwatches
IPC: G04C10/00
Filed: 1984-11-24
Abstract: The invention relates to a crystal mechanism having an electrical drive (crystal module), especially for wristwatches. In this case, it is intended to create a new drive system for crystal watches, which drive system, however, continues to guarantee time accuracy but in which there are no batteries or rechargeable batteries as the energy source. This is made possible by means of a spring clockwork mechanism as an energy store which, by means of a transmission system having rotation-speed control, supplies an electrical generator in order to emit a virtually constant power (voltage) to the electrical watch drive (crystal module). <IMAGE>

Patent DE-3634372-A1 (DE)
Title: Bobbin plate
Inventor: SIEBERT GEORG
IPC: D01H7/86
Filed: 1986-10-09
Abstract: To mount the bobbins on the bobbin plates of two-for-one twisting machines, the bobbin plates conventionally have mandrels, onto which the bobbins are slipped. This necessitates a particular constructional height of the two-for-one twisting spindle, since the bobbins have to execute an axial movement in order to be slipped on. To avoid this, the tubes are provided with tabs (56) on a circumferential edge. The bobbin plate has clamping clips on a corresponding circumference. The bobbin is fastened on the bobbin plate by moving the tabs into the clamping clips. <IMAGE>
Patent DE-3640830-A1 (DE)
Title: Fuel injection valve
Inventor: KIND WILHELM DIPL ING
IPC: F02M51/06
Filed: 1986-11-28
Abstract: A fuel injection valve is proposed, which serves for the injection of fuel into the intake pipe of a mixture-compressing internal combustion engine with applied ignition. The fuel injection valve comprises a nozzle body (9), in which a valve seat face (48) is formed. A valve needle (27), to which an armature (14) is fixed, which is electromagnetically actuated by a solenoid (3), co-operates with the valve seat face (48). The valve needle (27) has a first guide section (40) close to the valve seat face (48) and a second guide section (39). Downstream of the valve seat face (48) a small plate (55) is arranged, on which four bores (80) are formed at regular intervals from one another. The guide sections (39, 40) have surfaces (41) running approximately in the direction of the valve's longitudinal axis, which are uniformly distributed over the circumference of the guide sections (39, 40) and give the guide sections (39, 40) a pentagonal form, resulting in an improved uniform distribution of the sprayed fuel masses on the fuel injection cone and reducing the dependence of the static rate of flow on the annular position of the valve needle (27). <IMAGE>
