Patent DE-3104563-A1 (DE)
Title: Arrangement for the simultaneous and independent control of two apparatuses which are driven by electric motors and are supplied from a common two-wire supply line
Inventor: FUGGER ADOLF
IPC: H02P5/68
Filed: 1981-02-10
Abstract: For the simultaneous and independent control of the rate of movement and movement direction of two electric motors which are supplied from a common two-wire supply line, the negative and positive voltage elements which are used for supplying power to the individual motor are preceded or followed by short voltage pulses whose amplitude is greater than that of the first voltage element. These pulses govern the movement direction, while the amplitude and/or duration of the voltage element determine/determines the rate of movement of the respective motor. In contrast to the previously known circuits for the simultaneous and independent control of two electric motors from a common two-wire supply line, in the case of this circuit, the movement direction of both electric motors can be predetermined at the start of operation. A special locking circuit in the receiver allows the pulse which determines the movement direction also to be less than or equal to the maximum peak amplitude of the voltage elements occurring in operation.

Title: Ink jet printer
Inventor: HORIKE MASANORI
IPC: B41J2/12
Filed: 1981-02-28
Abstract: After setting an ink droplet charge phase in an ink jet, a line is printed by deflecting the ink jet by a number of incremental points and during this time a binary image signal is applied to the ink jet. The correct deflection value of the ink jet is set along an axis between the previously mentioned stages by scanning or sweeping the ink jet. An interception electrode (80a) is provided along the axis which is intersected by an edge. The ink jet deflection is stopped if an output of an integration circuit (220) indicates that the ink jet has reached the edge. An electrical signal is then generated which indicates the size of a deflection force which is applied to the ink jet at the time when it reaches the edge. A voltage amplification factor for deflecting the ink jet over the incremental points is set in accordance with the size of the electrical signal. <IMAGE>

Title: Explosion-proof and firedamp-proof luminaires
Inventor: MITSCH HERBERT
IPC: F21V25/12
Filed: 1981-03-25
Abstract: The explosion-proof and firedamp-proof luminaires according to the invention are designed in such a way as to prevent the intrusion of explosive gas-air mixtures into the interior of the luminaire housing, and such that the surface temperatures of the luminaires are below the lowest ignition temperature. As a result, previous expensive measures for the avoidance of ignition temperatures such as, e.g., by means of special lamps or switches, mounts and ballasts etc. or heavy pressure-proof housings provided with precision fits are eliminated. Upon expiry of the lamp service life, a change of luminaire is undertaken instead of a change of lamp, and the old luminaires are handed back to the luminaire manufacturer in an exchange process. Fig. 1 of the patent drawing shows an appropriate example, Fig. 2 represents a variant in which the lamp and starter or ballast and condenser are respectively accommodated in separate gas-tight housings. In this case, the lamp housings can be exchanged without having to detach the luminaire connection. Figs. 3 and 4 show arrangements in the case of multi-lamp designs, Fig. 4 representing a ballast housing having a plurality of lamp housings. <IMAGE>

Patent DE-3138213-A1 (DE)
Inventor: SCHULTE GERD
IPC: G03B35/08
Filed: 1981-09-22
Abstract: In opposition to known stereo systems, with oblong stereoscopic images, the system, object of the invention, offers a maximum of projection security and comfort and allows at the same time the construction of particularly simple, small and universal cameras. In fixed relationship with stereoscopic images, (1, 2) turned in opposite directions, there are arranged reference marks (4) which, during reproduction, are optoelectronically scanned and provide for the compensation of level or convergence errors by means of a bridge-adjusting circuit and one or a plurality of motors. The camera further allows the automatic recording of data, without affecting the content of the image. The stereo camera and the stereo projector are closely connected constituent elements which are part of unitary system or appear as two forms of execution based on the same principle. The system benefits from the numerous advantages of stereoscopy, advantages which could also be obtained with other systems but which only here appear to be really usable in practice.

Title: Three-dimensional image reproduction method
Inventor: ORTH LOTHAR
IPC: H04N13/363
Filed: 1981-11-14
Abstract: The invention makes it possible to allow the images reproduced on two-dimensional image reproduction screens (screens of television sets, projection walls and so forth) to appear as three-dimensional, that is to say solid, images to a viewer. This is achieved by the fact that the two different images of a single object, which produce a three-dimensional impression for a viewer, are reproduced successively in time on the reproduction screen. The viewing requires a device (special glasses or viewing window) which makes it possible for the eyes of a viewer to see these two images not simultaneously but also in succession. This is achieved by the fact that the eyes of a viewer are in each case alternately covered at the right instant so that the left eye always sees only the image belonging to the left eye and the right eye only sees the image belonging to the right eye. With a suitable image sequence, a three-dimensional image impression is produced at the viewer. Main fields of application: three-dimensional (also coloured) television images (for example transmission of operations in medicine), video games, radar images, X-ray images, transparency projection, film projection, computer terminals, aircraft and vehicle simulators.

Title: Measurement value conditioner
Inventor: HALDER MATHIS
IPC: G01R21/133
Filed: 1982-02-18
Abstract: A measurement value conditioner (2) for processing periodic digital samples of two measured alternating voltages of the same frequency shifted by the phase angle  phi . The samples of the first alternating voltage are stored in a random access memory (8) with the aid of a selector (6) at addresses which are equal to the binary counts of a counter (3). In each case one multiplier (10, 14) digitally multiplies the samples of the two alternating voltages by particular stored values called up from the random access memory (8), an accumulator (4, 5) generating the addresses of the stored values called up by digitally integrating the output signal of the associated multiplier (10, 14) and subsequently adding it with the aid of an N-bit adder (15) to the currently valid binary count of the counter (3) so that the stored values called up are equal to the values of the first alternating voltage shifted by a certain phase angle ( pi /2,  phi  +  pi /2) compared with the sampling instances. A subtraction element (16) forms the difference ( phi ) between these two phase angles. The measurement value conditioner (2) can be used in electricity meters. The second alternating voltage is then proportional to the consumed power. <IMAGE>

Patent DE-3209601-A1 (DE)
Inventor: SCHWARTZ WILLI
IPC: A62B9/00
Filed: 1982-03-17
Abstract: A pressure indicator, particularly for respirators, comprises a housing which has a pressure chamber, is connectable to a pressure source, for example a respirator gas pressure and includes a plurality of individual indicator chambers which is connected to the pressure chamber with an indicator piston member slidable in each of the chambers and biased by individual springs in a direction which brings a feeler portion of the indicator piston member within the housing. The feeler portion extends out of the housing in an indicating position which position is arrived at by pressure in the pressure chamber acting on the indicator piston to force it out of the housing. Each indicator piston member is biased by a biasing force, for example, produced by a selected spring so that it will be in a non-indicating position until a distinct pressure acts on the indicator piston member to force it in a position in which the feeler portion thereof extends out of the housing. The individual feeler portions of the indicator piston members are advantageously covered by a flexible covering which is provided with individual projecting portions which provide housings for the feeler members. The covering is such that the individual feelers may be sensed as being present in the projecting portions of the covering when the pressure chamber of the device has reached a predetermined pressure and forces this particular feeler into the projection.

Title: Method for reducing interfering reflections during rangefinding by microwaves
Inventor: SCHIEK BURKHARD PROF DR ING
IPC: G01S13/32
Filed: 1982-05-05
Abstract: The invention relates to a method for reducing the interfering influence, particularly of near reflections during the evaluation of the total phase deviation, preferably during rangefinding by microwaves, in accordance with the principle of frequency-modulated continuous-wave radar. For this purpose, in each case two values, adjacent in frequency, of the transfer function of a range measuring system are vectorially subtracted and the phase differences between the difference vectors obtained are added together over the frequency within the bandwidth used for the analysis. The total phase deviation thus obtained is a measure of the distance of the main reflector which, in comparison with the total phase deviation obtained directly without forming a difference, is falsified by interference reflections only to a greatly reduced extent. <IMAGE>

Title: Multiple-disc brake
Inventor: JAKUBOWSKI KARL-HEINZ ING GRAD
IPC: F16D55/38
Filed: 1982-06-08
Abstract: The invention relates to a multiple-disc brake having outer and inner discs which can be pressed against a thrust plate by means of the force of a cup spring, which bears on the one hand against the end face of a pressure piston and on the other hand against the housing end face, and which discs can be lifted by the pressure piston by means of a pressure medium. In order to design a multiple-disc brake of the type mentioned in the introduction, in such a way that the brake volume can be reduced and the built-in spring has a force trend largely constant in the working range, it is proposed that a prestressed cup spring (15), which can be pressed out of its initial position beyond the plane position, should act against the pressure piston, and that the cup spring bear with the inside diameter against an annular projection located on the piston end face and with the outside diameter against an annular projection located on the housing end face. <IMAGE>
