Patent DE-3042969-A1 (DE)
Title: Drainage plug for fluid tank - has sealing ring around shaft with lateral drain bore
Inventor: BURGMANN DIETER
IPC: F01M11/04
Filed: 1980-11-14
Abstract: The drain plug bore has a tapered bottom end leading to a shaped seal section (8) into which the 0-ring seal (7) around the plug shaft is pressed to seal the sump. A lateral bore (2) leads to a wider end of the drainage plug bore so that when the plug is partially withdrawn oil can drain out of the lateral bore. The drainage plug acts as a tap and has no oil spilling out of its main thread. This allows the operator to drain the sump without oiling his tools and hands. When the oil pressure head is reduced sufficiently then the whole plug can be withdrawn.

Title: Input and display of setting values in electronic equipment - has stored digital values called by rotary selector for control of cooker temperature
Inventor: SEYER REINHARD DIPL ING
IPC: G05B19/10
Filed: 1980-12-24
Abstract: A rotary selector input for use on domestic cookers is designed to provide a digital setting value that is displayed. The rotary input is turned (10) and produces pulses (12) that are reduced by a divider (13) to trigger a bi-directional counter (7). A specific count value, which corresponds to a specific angle of input selector rotation, provides access to a memory (19) that generates an output indicating a temperature range, e.g. 0,240 or 280 degrees. The values are transmitted to a buffer memory (20) and are decoded (15) for display (14).
Patent DE-3100540-A1 (DE)
Title: Instrument for motor vehicles for warning of skidding
Inventor: OHMACHT PETER
IPC: B60R16/02
Filed: 1981-01-10
Abstract: The invention is based on the fact that many accidents happen which are due to a motor vehicle driver underestimating the degree of bending of a road and thus driving into a bend at an excessively high speed, as a result skidding and leaving the carriageway. Accidents of this kind are not only caused by learners but also by experienced drivers. A further source of danger can be found with caravans and trailers of lorries. Here, the behaviour of the towed vehicle is usually only perceived when the vehicle is already carrying out dangerous rolling motions because of excessively high speed. The system for warning of skidding continuously detects the instantaneous behaviour of the vehicle as a function of speed, the degree of bending, centrifugal force and tyre grip, by means of the displacement of magnetic force fields. A visual display and acoustic indicator warn the driver in the passenger compartment of the imminent risk of his vehicle getting out of control, from which the driver can draw appropriate conclusions. An automatic system which is controlled by means of a thermostat and hygrostat continuously determines the current state of the road and thus ensures a prompt forewarning not only when the road is dry but also when the road is wet and icy.
Patent DE-3104910-A1 (DE)
Title: Baking oven
Inventor: KLEMENT JOHANN
IPC: F24C7/06
Filed: 1981-02-11
Abstract: In known baking ovens with supplementary parts for catalytic self-cleaning and with radiant-heating elements which are built in or can be built in, expensive design measures are necessary for the purpose of fastening the aforementioned parts, preferably in a releasable manner. According to the invention, the baking oven is to be equipped such that the aforementioned parts can be mounted and demounted in a simple manner even by the layperson. This is achieved according to the invention in that there is arranged, along each lateral muffle wall (5, 6), a rail (7) in which the associated side wall can be hung or pushed and which serves as carrying member for the radiant-heating element (2). <IMAGE>
Patent DE-3111785-A1 (DE)
Title: Window profile
Inventor: HUEBERNER OTMAR DIPL ING
IPC: E06B3/58
Filed: 1981-03-25
Abstract: The invention proposes a window profile made of plastic, preferably a glass strip which consists of a main body and a catch foot which are interconnected via a hinge, it being possible for the glass strip to be manufactured as a whole using the extrusion method and for the hinge to consist of a corresponding reduction in wall thickness in relation to the profile body. By using the proposed glass strip, the mounting of windows made of plastic profiles is easier. The main body of the glass strip can be pivoted towards the glass pane together with the seal, the catch foot being supported with an extension in the main body of the profile. The catch connection between main body and catch foot of the glass strip is releasable in order for example to be able to open the glass strip again in the event of damage, so that the glass can be removed from the window profile. The glass strip can subsequently be re-used. The time expended for the mounting of a pane can be reduced with the subject of the invention, it being of particular importance that the seals i.e. glazing seals can already be drawn in or rolled in before mounting.

Title: Electromechanical transducer
Inventor: HERDEN WERNER DIPL ING
IPC: G01D3/02
Filed: 1981-07-15
Abstract: An electromechanical transducer is proposed in which at least one magnet cooperates with at least one component which is sensitive to magnetic fields and whose position can be varied in relation to the magnet. In order to linearise the total characteristic of the transducer, in this case the magnet characteristic, i.e. the induction, is linearised as a function of the distance from the magnet by making use not of one magnet but of a combination of two component magnets (1, 2; 1', 2') which are juxtaposed with like poles. By suitable choice of the dimensions of the component magnets (1, 2; 1', 2'), it is achieved in this way that the total characteristic of the magnet is linear in at least one subregion. <IMAGE>

Patent DE-3137571-A1 (DE)
Title: Medium-voltage switching installation
Inventor: KRAEMER WILHELM
IPC: H02B5/06
Filed: 1981-09-22
Abstract: A medium-voltage switching installation which is arranged in a switch panel has at least one three-pole power circuit breaker whose circuit breaker poles (30, 32, 34) are connected at one of their ends to busbars (12, 14, 16) and at their other end to cable outlets (88, 90). In order to reduce the size of the actuating surface, the phase conductors (12, 14, 16) and the circuit breaker poles (30, 32, 34) (which are connected to the phase conductors) of the power circuit breaker are arranged one above the other. In addition, the centre axes of the individual circuit breaker poles, which in each case form a power circuit breaker, run parallel to one another and at an angle with respect to the plane (E) in which the connecting points of the circuit breaker poles of the power circuit breaker to the phase conductors are located or to the plane in which the phase conductors of the busbar lie. It can also be said that these centre axes run at an angle to the base plane. In order to simplify the storage and production outlay, each circuit breaker pole (30, 32, 34) and each phase conductor (12, 14, 16) is surrounded in the region of the connecting points by an L-shaped or T-shaped encapsulation element, so that the encapsulation openings located transversely with respect to the axes of the phase conductors and of the circuit breaker poles can be connected to one another. <IMAGE>

Title: Geared pump for the delivery of liquids, particularly a lubricating oil pump for internal combustion engines
Inventor: KRUEGER HERMANN DR ING
IPC: F04C2/20
Filed: 1981-10-02
Abstract: In the case of a geared pump two sets of toothing are assigned to the two interacting pump gears (3, 5), one of which sets of toothing (6, 7) serves almost exclusively for transmitting kinetic energy from the directly driven pump gear (3) to the other pump gear (5) and is so designed that an uninterrupted positive tooth form engagement occurs, whilst the other toothing (8, 9; 10, 11) as pump toothing is of much broader design than the first mentioned toothing and has fewer teeth (8, 9; 10, 11), so that the impairment of efficiency due to squeezing out of liquid in the tooth engagement is minimised. <IMAGE>

Title: Method and apparatus for three-dimensional electrical discharge machining
Inventor: INOUE KIYOSHI
IPC: B23H7/38
Filed: 1981-10-08
Abstract: Method and apparatus for the electrical discharge machining of a three-dimensional hollow space (36) in a workpiece (11), with a thin, preferably tubular and continuous tool electrode (1), the shape of which is generally independent of the desired shape of the hollow space. A horn-sound or ultrasonic unit (19) or a motor-driven mechanical reciprocating unit is used for the lateral oscillation of the thin electrode (1) for the purpose of moving its machining tip part (1a) in an oscillatory manner at a rate of motion of preferably more than 5 m/min essentially in a plane perpendicular to the electrode axis. The machining fluid is pumped into the tubular electrode (1) and is thereby delivered into the machining gap (G) at a pressure of over 10 bar. Feed means (12-16) produce a three-dimensional relative movement of the electrode axis and the workpiece (11) for the purpose of  three-dimensional sweeping of the workpiece (11) by the laterally oscillating electrode tip (1a) in a tracing manner, while successive electrical discharges are produced between the laterally oscillating electrode tip (1a) and the workpiece (11), and the machining gap (G) in between, which is flushed with the machining fluid, is essentially kept at a constant size. <IMAGE>

Title: Device for the detachable attachment of a hydraulic fluid line to a hydraulic fluid connection
Inventor: REINECKE ERICH ING GRAD
IPC: F16L19/028
Filed: 1981-10-30
Abstract: The invention relates to a device for the detachable attachment of a hydraulic fluid line to a hydraulic fluid connection. The hydraulic fluid connection has a stepped internal hole into which the hydraulic fluid line is inserted by means of its free end region. A subregion of the stepped internal hole is used as a guide for the free end of the hydraulic fluid line. A sealing ring which encloses the hydraulic fluid line is arranged between a step in the internal hole and a bead provided on the circumference of the hydraulic fluid line, by means of which sealing ring the necessary sealing is produced between the hydraulic fluid line and the hydraulic fluid connection. A coupling part which is pushed onto the hydraulic fluid line is connected to the hydraulic fluid connection by means of a snap, screw or bayonet fastener. The bead which is arranged on the circumference of the hydraulic fluid line is in this case clamped in between the sealing ring and the coupling part, so that the hydraulic fluid line is secured against axial displacement.

Patent DE-3205143-A1 (DE)
Inventor: LIPINSKI REINHARD
IPC: F16H25/20
Filed: 1982-02-13
Abstract: A stiff, form-stable elongated tubular housing (1) is formed with an axially extending longitudinal slit (12). A drive spindle (4) is retained in bearings (8) located in end flanges (2) of the housing, driven for example by a motor (M). A pair of spindle nuts (5, 6) clamp, between themselves, a tubular portion (15) of a force transfer element (14) which is located externally of the housing and moved by a web (13) passing through the slit. The force transfer element is guided on the housing by interengaging groove and projection means (20, 21), which also isolate forces applied to the force transfer element from the spindle drive. The slit is closed off by a flexible web (23) which is lifted out of the slit in the region of the force transfer element by camming surfaces (33, 34) passed through a transverse opening (32) in the force transfer element, and re-seated in the slit by roller-and-pusher elements (35, 36, 37) which snap outwardly extending projections (30) of resilient web strips (28) behind the walls of the slit (12) to form a completely enclosed housing in which the spindle and spindle nuts are protected from environmental contamination, and which can retain lubricant for high-efficiency, low-noise force transmission and conversion.

Title: Concrete-spreading apparatus
Inventor: AINEDTER DIETER DIPL ING
IPC: B28B13/02
Filed: 1982-03-08
Abstract: In order to place the concrete mass in an exactly proportioned manner in a formwork by means of a rotary vane feeder (3, 4), the vane wheel (3) with its vane elements must be matched accurately to the annular channel (4) in which the vane wheel rotates. Sizable stones sometimes cause high jamming stresses to occur here at the free ends of the vane elements, which result in the flexible sealing strips at these ends being torn off. In a further development of the concrete-spreading apparatus according to the main patent 3041905.7, it is proposed either to make the vane elements (5) on a broad fastening base over the entire height from a fully flexible material with a tooth-shaped cross-sectional profile (5') or else, instead of the vane elements, to provide the cylinder shell (31) of the vane wheel (3) with a vane-stud profile (50), the vane studs of which have blade surfaces running obliquely with respect to the direction of rotation. <IMAGE>

Title: Method for deleting value information on a credit card and device for carrying out the method
Inventor: CORBAZ ANDRE
IPC: G07B11/11
Filed: 1982-04-16
Abstract: An ultrasonic pen (1) acts with its point (14) on the surface of a credit card (9) containing value units and heats up a locally limited part of a carrier layer (11) of the credit card (9) by means of oscillations. A temperature increase arises in the material itself and causes the structures used as value units in the carrier layer (11) to fuse. This destroys the structure. A suitable structure consists of holograms, the presence and authenticity of which can be visually checked by means of a hole (12) in a guide track (8). <IMAGE>
