Patent DE-3149957-A1 (DE)
Title: Direction-finding arrangement
Inventor: BODEMANN GERHARD DIPL ING
IPC: G01S3/48
Filed: 1981-12-17
Abstract: From the antenna voltages of two receiving antennas of an interferometer direction-finding arrangement, a sum voltage and a difference voltage are obtained by means of a sum-difference section and the difference voltage is phase-shifted by 90 DEG . The two voltages are then modulated in two modulators at the rate of a low-frequency oscillation with 90 DEG  phase difference. The two modulated voltages, together with the antenna voltage of a reference antenna, are combined to form a radio-frequency oscillation amplitude-modulated with reference frequency. The fundamental wave of the envelope is filtered out of this radio-frequency oscillation. The phase difference between the fundamental wave and the reference oscillation provides the direction-finding angle.

Title: Electrical switch with a lighting device
Inventor: MUTSCHLER ERICH
IPC: H01H23/02
Filed: 1981-12-24
Abstract: In an electrical switch having a switch housing, having an operating device and having a lighting device which has at least one light element, at least one light outlet window and at least two variously-coloured filters which enable the existing light outlet windows to be illuminated in different colours in the various switch positions, it is intended to reduce the mechanical complexity required for the illumination. This is achieved according to the invention in that the two coloured filters are arranged in one switch position such that the light passes through both coloured filters to a light outlet window. The effects of the two coloured filters are thus superimposed so that a third colour is produced by additive or so-called substractive colour mixing.

Title: Storage device for mounting in motor vehicles
Inventor: OBERWELLAND KLAUS
IPC: B60R7/08
Filed: 1981-12-24
Abstract: Storage devices for magnetic recording tape cassettes or the like, for mounting in motor vehicles with a housing subdivided into compartments and an attachment device arranged thereon are installed in a known manner in the dashboard area or on the transmission tunnel between the front seats of a motor vehicle. This is disadvantageous above all because of the damaging effects of light and sun. Therefore, the storage system is to be constructed in such a way that it can be attached directly under the vehicle roof, without a troublesome hangover downwards, within the reach of the vehicle occupants, even subsequently without changing the vehicle fixtures. For this purpose, it is composed of a housing which is of elongate, flat design in its lateral direction and whose compartments are arranged one next to the other in this lateral direction and are open towards the rear longitudinal side of the housing. Here, a clip arranged at the front longitudinal side of the housing serves for mounting.

Patent DE-3205160-A1 (DE)
Title: Throttle valve for an intake line of circular cross section of an internal combustion engine
Inventor: SEUFER THEO DIPL ING
IPC: F02D9/10
Filed: 1982-02-13
Abstract: The said throttle valve is formed by a spherical zone by means of which the said throttle valve can be brought into a closed position which is such that it must first be swivelled over a larger range before clearance of the passage cross section of the intake line commences. The adjustment travel of the throttle valve preceeding actual clearance of the passage cross section can therefore be used for actuation of switch elements. By means of a one-sided tapering of the throttle valve it is also possible to achieve a progressive opening characteristic and a good meterability of the passage cross section in the lower operating range of the internal combustion engine.

Title: Combustion engine with rotary ram supercharger
Inventor: KICKBUSCH ERNST DIPL ING
IPC: F02B37/11
Filed: 1982-03-02
Abstract: A combustion engine attains optimum characteristics for driving motor vehicles, especially passenger vehicles, through combination with a rotary ram supercharger, according to European Patent Application A10012329, the advantages of which are fully exploited throughout the speed range. This supercharger feeds charging air to the engine under pressure throughout the operating range and also utilises the exhaust gas energy. At the same time according to the invention the engine exhaust gases are fed to the supercharger functioning exclusively on the displacement principle, modifying the engine compression range so that in order to fully utilise their energy they are further expanded in the expansion chambers of the supercharger, whilst at the same time charging air compression is initiated so that at full load connection to the engine compression line occurs in such a way that, despite the falling engine compression the final pressure of the original compression is achieved. In accordance with the enlargement of its compression chamber necessary for reduction of the engine compression, its output can be correspondingly increased, the engine characteristic at the same time being improved through better adjustment to the requirements of vehicle operation. Together with the increase in output and the reduction thereby possible in the engine speed, the specific fuel consumption is also significantly reduced by the optimum air ratio. Suitable technical solutions for implementing these possibilites are indicated both for petrol and for diesel engines, which lead to the favourable characteristic curves of a system of the type according to Fig.8. Fig.3 gives a concept for the modification of the engine diagram by means of working chambers, Fig.1 the rotary ram supercharger. <IMAGE>

Title: Sleeve-shaped tool holder for hammer drills
Inventor: GEIS WILHELM DIPL ING
IPC: B25D17/08
Filed: 1982-06-03
Abstract: A sleeve-shaped tool holder for hammer drills, to which a control sleeve for locking and unlocking the tool is allocated in such a way that, by rotation of the control sleeve, the elements locking the tool in the tool holder are displaced forward from any rear position so that the locking elements can enter in a functionally correct manner into the grooves provided in the tool shank, as a result of which the tool can be locked in the tool holder in any working position, is to be improved to the effect that the control sleeve and the mechanism for the axial displacement of the locking elements become simpler and less costly. This is done according to the invention by virtue of the fact that the control sleeve is connected to an adjusting disc in such a way as to be locked against rotation, and the adjusting disc is provided with cams which run at least approximately perpendicularly to its plane and of which in each case at least one is allocated to a locking element, and this locking element, when it is located in its rear position, is displaced forwards during the rotation of the control sleeve.

Patent DE-3300486-A1 (DE)
Title: Dog stopping and training apparatus
Inventor: KULLMANN WILTON
IPC: A01K15/02
Filed: 1983-01-08
Abstract: In conjunction with a piezo-triggering device inserted in the slide cylinder during installation into the dog collar chain, the apparatus makes it possible to create a short painful influence on the dog, in the event of a sharp jerk, because of a current shock. The piezo-current is inadequate in the case of large dogs, and the same apparatus can thus be used in conjunction with an induction coil and battery. A pressure switch can be inserted in the slide cylinder instead of the piezo-triggering device. In this case, the apparatus can be inserted between the lead and the leather collar, which has two contact points on the inside. Contact triggering can be regulated by force in both cases, by means of the replaceable outer spring. <IMAGE>

This cycle wall mount achieves the object of accommodating cycles in the restricted space in garages or cellars in a space-saving and secure fashion. The cycle wall mount consists of only two components (component 5 and 6) in accordance with the enclosed drawing 1/2. As a result, the cycle can be suspended and removed effortlessly. In addition, this structure is inexpensive to manufacture. Function: the pedal bracket (component 5) is attached to the wall with two screws at a height of approximately 1-1.5 metres. It is designed in such a way that a bicycle pedal can be effortlessly hooked onto it. As a result of the oblique position of the pedal holder, the cycle is pressed against the wall with its tyres. The wheel holder (component 6) has the function of holding the cycle in a horizontal position and provides the possibility of securing the cycle with any wheel lock by means of a bore (14). By attaching the bicycle in an elevated position, free space is provided in the lower space of a garage or cellar and thus the space available is not adversely affected. <IMAGE>
Patent DE-3320478-A1 (DE)
Title: Method and arrangement for automatic build-up welding
Inventor: FABER WILFRIED DIPL ING
IPC: B23K9/04
Filed: 1983-06-07
Abstract: The invention relates to a method and an arrangement for automatic build-up welding which permits material build-up up to a preselected layer thickness irrespective of the local degree of wear of a workpiece. According to the invention, the welding torch is guided parallel to the required workpiece surface, and the feed rate of the welding torch is controlled by a signal which corresponds to the difference between the desired height of the build-up weld and the instantaneous value reached. The signal itself is obtained from the arc. The setting values for the welding current and the welding voltage are readjusted for constancy during the welding of a layer after they are set, and the instantaneous working point is detected by simultaneous current/voltage measurement. The deviations from the predetermined straight working lines are analysed by division and subtraction, after which an absolute-value adjustment is made. The analogue information signal available, of positive or negative sign, is used to control the feed rate of the welding torch in the welding direction. Parameter fluctuations due to the equipment technology are compensated for in the process by changing the distance.
