Patent DE-3425815-A1 (DE)
Title: Carrying handle and method for its manufacture
Inventor: QUITTER EGON
IPC: A45C13/26
Filed: 1984-07-13
Abstract: A carrying handle consisting of a bar with a web, limbs bent at 90 DEG , and bearing pins which are again bent at 90 DEG  and run parallel to the web, as well as attachment straps which each have a groove with a U-shaped cross-section and a central opening for inserting and guiding one bearing pin in each case. The technical problem is to construct a carrying handle of the type mentioned in such a way that the bearing pins can be connected to the respective connecting strap to form a unit which can be preassembled so that the carrying handle can no longer be detached from the attachment straps. The overall unit can then be passed on for welding to the lid. The portions (11) of the groove walls running approximately parallel to one another each have humps (12) pointing towards one another, and the spacing of the peaks of the humps (12) is smaller than the diameter of the bearing pins (5). A method for producing the carrying handle is distinguished by the fact that the groove is only bent to completion after the handle bar has been inserted. <IMAGE>
Patent DE-3430835-A1 (DE)
Title: Apparatus for measuring the flow rate of gaseous or liquid media
Inventor: BLIESENER DIETER
IPC: G01P5/14
Filed: 1984-08-22
Abstract: Apparatus for measuring the flow rate of liquid or gaseous media, having a device for producing an effective or dynamic pressure which can be inserted into the line for the media flow and having a displacement sensor with a final control element which can be displaced by the effective or dynamic pressure against the force of a spring. In this arrangment, the spring is designed as a leaf spring or bar spring with a linear characteristic, which spring rests freely on two points and forms the opposing force to the spring load caused by the effective or dynamic pressure. The final control element, which exerts the spring load, engages on the spring preferably in the centre between the resting points. In the bending plane of the spring there is arranged a curved track, on which with punctiform loading the spring is supported at the points of contact tangentially with respect to its respective bending line. In this arrangement, the free bending length determining the bending rigidity changes with the flexing of the spring in such a way that a spring flexing which is quadratically proportional to the spring load or the effective or dynamic pressure is obtained. The adjustment of the final control element from the zero position in the displacement sensor consequently produces a measured variable which is linearly proportional to the flow rate.

Patent DE-3434607-A1 (DE)
Inventor: MARQUARDT RAINER DR ING
IPC: H03K17/18
Filed: 1984-09-18
Abstract: This invention concerns a procedure to operate a turn-off thyristor which can be set to a current-conducting state or a current-blocking state as a function of a switch-on command or a switch-off command. To permit particularly reliable and optimal operation of the turn-off thyristor, the voltage between its gate terminal, G, and its cathode terminal, K, is detected and when it drops below a negative threshold current value UGKS, a status signal, Z, is generated which indicates the current-blocking state of the turn-off thyristor. A further embodiment detects the gate current of the turn-off thyristor and after the appearance of the switch-off command, the status signal is generated as the polarity changes in accordance with the time derivative of the gate current. An overload of the turn-off thyristor is best recognized by having simultaneous to the appearance of the switch-off command, a time function with a preset expiration time initiated, and having a malfunction notification signal, F, generated for protective ignition of the turn-off thyristor if the time function expires prior to the appearance of the status signal.

Title: Contactless determination of the object position and object properties during welding
Inventor: SCHAUDER VOLKER DIPL ING
IPC: G01B7/14
Filed: 1984-10-04
Abstract: The invention relates to the contactless determination of the object position and object properties during welding. The aim is to ensure precise determination of the position and/or the dielectric properties of objects under extreme environmental conditions. Apart from determining distance between a welding or cutting torch and a workpiece in the immediate vicinity of the arc or the flame, the aim is, furthermore, also to enable determination of the distance from dielectric materials or of the dielectric properties thereof. The method provides that in accordance with the invention an electromagnetic alternating field is distorted in a defined way, the field strength in the stray field region is determined essentially opposite to the measurement direction or the measurement directions by measuring at least one received voltage, and the received voltage is compared with the scaled transmitted voltage. The claim of the invention contains the device for carrying out the method. <IMAGE>
Patent DE-3436585-A1 (DE)
Title: Safety rim for motor vehicles
Inventor: BIALETZKI KLAUS
IPC: B60C17/02
Filed: 1984-10-05
Abstract: With this rim, absolute safety against a sudden blowout of a tyre is ensured. In combination with an air pressure indicating device (on the dashboard), it permits a spare tyre to be dispensed with. An air pressure reservoir chamber which is inflated to the necessary ratio to the tyre pressure is attached to the rim. Between the air pressure reservoir chamber and the safety hose located in the tyre, a plurality of pressure compensation valves are attached to the circumference of the rim. The tyre and the air pressure reservoir chamber each have a normal valve for inflation. If the pressure in the tyre drops for any reason whatsoever below the permitted limit, the pressure compensation valves are pressed through into the tyre air space. The safety hose, which withstands travel stresses even when the tyre is severely damaged, is inflated again to the required tyre pressure. The number of pressure compensation valves is chosen to be such that in the event of a sudden blowout of the tyre the air which escapes can be replaced again within seconds. If the pressure drop or damage to a tyre is indicated, the spare tyre can be dispensed with.

Title: Process and equipment for producing cast explosive charges
Inventor: HALLER ARMIN
IPC: F42B33/02
Filed: 1985-04-02
Abstract: For producing cast, in particular plastic-bonded explosive charges having a defined geometrical shape at one end, a cover (2) is arranged at the upper end of the charge envelope (1), which cover consists of an outer part (3), which can be fixed to the charge envelope (1) and is provided with overflow orifices (6), and of an inner part (4), the cover (2) having a shape corresponding to the geometrical shape of the charge, when the inner part (4) is pushed into the outer part (3). After filling of the interior of the charge envelope (1), the inner part (4) is then pushed into the outer part (3), whereby the excess of explosive is displaced into the overflow orifices (6). The explosive is then allowed to solidify. If the inner part (4) is a fuse hole bush, this remains in the explosive charge. The same applies to the outer part (3) if it is formed by the final closing cover of the charge. <IMAGE>

Title: Covering for clarification plants
Inventor: KOENIG KLAUS DIPL ING
IPC: C02F1/20
Filed: 1985-04-11
Abstract: A device for disposing of the waste from clarification plants, sludge-dumping areas or the like which generate gases has a covering (2), which spans the dumping area and prevents the gases from escaping freely, and a drawing-off system (24) for the gases. In order to reduce, in particular, the possible effects of natural forces on said covering, the latter is connected to an edge-gripping means (23), surrounding the edge (11) of the dumping area (1), and to floats (22) floating on the surface (12) of the dumping area, such that the covering is located in each case directly over the surface (12) of the dumping area. It can thus be adapted in each case to a changing dumping-area level, is inexpensive, easily exchangeable and can be assembled on site from prefabricated structural elements, operating costs being reduced as the area spanned is decreased.
Patent DE-3516100-A1 (DE)
Title: Method for cutting machining of turned parts, preferably of shafts, in particular of crankshafts, as well as device for carrying out such a method
IPC: B23C3/06
Filed: 1985-05-04
Abstract: Using the method, turned parts are machined by turn broaching, the turned part being turned about its axis and each cutting edge of the machining tool being, in relation to the turned part, moved about the axis of the machining tool as well as at the same time fed towards the turned part. The feed movement is consequently independent of the turning movement of the machining tool so that both movements can be varied independently of one another. The machining tool, which is located in a rotationally fixed manner on a spindle, can be turned about its axes by means of the turning drive. It is mounted on the feed drive so that the feed movement and the turning movement of the machining tool can be carried out easily.
Patent DE-3517260-A1 (DE)
Inventor: STALLKAMP HEINRICH
IPC: F02B53/02
Filed: 1985-05-13
Abstract: A rotary piston internal combustion engine with two counter-rotating pistons (14, 15) located on the same axis and engaging with one another. One of the pistons acts as a compression or charging piston and the other as an expansion or propulsion piston. The design is aimed at providing a favourable co-ordination between the charging piston and the propulsion piston with the operating chamber of the propulsion piston being several times that of the charging piston, and is such that the two rotary pistons, whilst maintaining conjugate peripheral angles of approximately 360<o>, possess different peripheral lengths which leave in the rotary piston paths, operating chambers of different sizes, which take into account a pressure increase between the inlet air and the combustion gas. Furthermore, effective operation is achieved by annular valve slides (29, 30) which are incorporated in the housing on both sides of the rotary pistons, whose outer radii together are smaller than the distance of the rotary axes from one another. In this way it is also possible to obtain a symmetrical bearing system on both sides of the rotary pistons for high engine rpm.
