Patent DE-3220189-A1 (DE)
Title: Potentiometer/switch combination
Inventor: PRESTEL FRITZ ING GRAD
IPC: H01H3/02
Filed: 1982-05-28
Abstract: A potentiometer/switch combination in which the individual structural components are arranged on a common carrier board. In this case, a linear resistor track is enclosed on both sides by potentiometer pick-off tracks in the form of metal brackets arranged at a distance from the supporting board; these metal brackets are gripped by latching tabs of a wiper, which itself is in turn formed from the compact latching of two parts, such that the pick-off tracks are the individual parts which support the wipers and simultaneously transfer the potential picked off from the resistor track. The rear surfaces of operating switching elements of snap switches which are preferably arranged in mirror-image symmetry on both sides are constructed adjacent to the track of the potentiometer wiper, such that, in one predetermined limit position of the wiper, the two switches have a specific switch position, namely being pretensioned in the switched-off position. If the wiper is moved along the resistor track, the switches on both sides are released, preferably for double-pole switching on.

Title: Side spill plate with an inner space accommodating the shearer cable
Inventor: HESS HEINZ DIPL ING
IPC: E21C29/04
Filed: 1982-06-12
Abstract: The invention relates to a side spill plate (1) which has an inner space accommodating the shearer cable. On the working-face side, the side spill plate (1) is provided with a removal opening (6) which extends over the length of the spill plate and through which the shearer machine (8), travelling along the side spill plate (1) on the face conveyor (3), reaches with an extension (9) and passes the end of the shearer cable out of the inner space of the spill plate into the machine body. The removal opening (6) is sealed off from the won minerals over its entire length by two elastic strips (7, 16). To this end, both strips (7, 16) have a width exceeding half the height of the removal opening (6) and overlap in such a way that the top strip (7a, 16a) lies in front of the outside of the bottom strip (7b, 16b). In addition, both strips (16) are provided with a circular beading (17) on their longitudinal edge lying in the overlapping area, which beading (17) projects in the direction of the overlap of the strip, or else the strips (7) are of tubular design. <IMAGE>

Title: Method for determining and displaying target data
Inventor: LEISTERER REINHARD DIPL ING
IPC: G01S11/14
Filed: 1982-06-14
Abstract: In this method, acoustic bearings are taken off noise sources and the target data are determined. In this connection, it is intended, in particular, to increase the reliability in the determination of the target data with passive measuring methods. For this purpose, mean values for bearing, time and own position are formed and continuously displayed with the target data determined on the basis of regression methods. The invention can be mainly applied to underwater vehicles in which the target data necessary for reliable navigation, for example range and speed, must be obtained from position representations and bearing/time plots.
Patent DE-3227619-A1 (DE)
Title: Heat exchanger
Inventor: IWAMURA HIROYUKI
IPC: F28D7/10
Filed: 1982-07-23
Abstract: A heat exchanger is presented which consists of an inner tube and an outer tube. By contrast with heat exchangers according to the prior art, the inner tube is formed from a tube and a tube enveloping this tube. The surface of one or both tubes is constructed to give rise to channels. This is achieved by producing ducts through extrusion or other suitable measures. The top sides of the ducts forming the channels serve the purpose of a tight fit between the tube and the enveloping tube. If, now, any damage occurs, eg. by corrosion between a flow channel in the inner tube and a flow channel, the fluid flows via the channels out of the heat exchanger into the atmosphere. It is possible to provide at the outlet known devices for detecting the escaping fluid and thus for indicating the leak.
Patent DE-3230055-A1 (DE)
Title: Triggering equipment for a pulse-controlled invertor
Inventor: KLAUSECKER KARL
IPC: H02M7/5387
Filed: 1982-08-12
Abstract: An oscillator having a variably predetermined nominal frequency forms the counting pulses of a counter whose counting state addresses a read-only memory. A binary nominal curve, which is predetermined independently of frequency, for the output voltage is stored in the read-only memory. The shape of the nominal curve is selected, for example, corresponding to a trapezoidal curve of constant amplitude which is modulated by means of a "first pulse-width modulation" at a duty cycle which is independent of frequency and amplitude. By comparing the amplitude control voltage with a triangular wave form scanning voltage, a second function transmitter produces a pulse-width signal by means of which an EXCLUSIVE-OR gate modulates the nominal voltage once again. The output signal is preferably used to drive power transistors which are used as invertor switches. The triggering equipment allows an output voltage which is optimised with respect to voltage utilisation and harmonic content to be predetermined in a simple manner for an invertor. <IMAGE>

Title: Apparatus for consolidating roadway pavings or the like
Inventor: RUGE HANS DIPL ING
IPC: E01C19/34
Filed: 1982-12-27
Abstract: The invention relates to an apparatus for consolidating, in particular, roadway pavings or the like, having a compacting beam which is movable over the roadway paving in the working direction and a device for producing from at least parts of the compacting beam compacting impacts which are directed mainly perpendicularly to the roadway paving. According to the invention, the apparatus is distinguished in that the underside of the compacting beam which lies on the roadway paving consists of mutually separated plate sections, and in that the plate sections are coupled to a drive mechanism which produces compacting impacts in such a way that mutually adjacent plate sections move in each case in opposite directions to one another. Each plate section is preferably a flat strip which runs in the longitudinal direction of the compacting beam and whose width is greater than the area of action of known tamping strips of tamper planks, but less than the bearing area of known vibratory planks. The measure according to the invention has the advantage that, in particular in the case of post-compaction, the disadvantages of the pre-compacting tamper planks or vibratory planks can be compensated for, since the apparatus according to the invention works both at high surface pressure like a tamper plank and also, at the same time, ensures deep action of the compaction, as is only achieved with vibratory planks.

Abstract: A hairdryer is equipped with two parallel-connected heating resistors (20, 24) and can be connected via three switches (26, 28, 30) to a voltage source (10, 40). Connected between the heating resistors (20, 24) is a fan motor (42) which is connected on its one side to a cathode connecting line (46) of two diodes (48, 50) and on its other side to the first heating resistor (20). Connected in parallel with the first diode (48) is a third diode (56) which is connected at one end to the output (31) of the first heating resistor (20) and at the other end to the output of the fan motor (42). The two diodes (48, 50) are connected asymmetrically to the two heating resistors (20, 24) in such a manner that the half cycles flowing via the first and second diodes (48, 50) are of different magnitude. In consequence, the speeds for the fan motor can be adjusted in fine steps. <IMAGE>

Abstract: An electrical connector and a method for its production are proposed, in which only a short region at the free end of a conductor, which projects beyond a contact section which is in contact with the conductor, is tinned. In this way, the two method techniques of "contacting" and "soldering" can be combined with one another without problems, and a connection is obtained which has good electrical properties even after a relatively long operating time.
Patent DE-3319943-A1 (DE)
Title: Radio-frequency pulse amplifier
Inventor: HONOLD PETER DIPL ING
IPC: H03K5/02
Filed: 1983-06-01
Abstract: In the radio-frequency pulse amplifier constructed in accordance with German Patent Specification 2904011, on the radio-frequency power transistor (2) of which a current with a desired pulse variation is impressed by means of a transistorised constant-current source, the radio-frequency power transistor (2) and the constant-current source transistor (15) are constructionally combined with one another, for example monolithically or in hybrid manner closely integrated in one casing or else arranged constructionally closely adjacently to one another in two casings on a common carrier or flange (21). The interfering circuit inductances normally occurring due to the unavoidable line lengths of the feed lines to the two transistors when discrete components are used are avoided by the invention so that lower operating voltages can be used, which results in a better efficiency of the radio-frequency pulse amplifier. A radio-frequency pulse amplifier constructed in accordance with the invention is particularly suitable for use in radar devices with high requirements for the edge steepness. <IMAGE>

Inventor: KUPFERSCHMITT WOLFGANG DIPL IN
IPC: H02P23/28
Filed: 1983-07-28
Abstract: An electric motor, for example an asynchronous motor, is proposed. Said motor is controlled by means of a microprocessor. In order to match the motor torque and the operating point to the required torque to be output, the control frequency and the control pulse width can be regulated. There is thus no need for a longitudinal regulator, the optimum slip being set at the same time, by feeding back the rotation speed and motor torque.

IPC: G02B7/34
Filed: 1983-08-30
Abstract: A sharpness-determining device is disclosed in which an object image generated on a prescribed focal plane of a photolens is once again projected by a second projecting optical system behind this focal plane into two object images which are not located one above another and are based on light bundle sections which are split up symmetrically relative to the optical axis of the photolens; light-sensitive elements are respectively arranged at the points at which these object images are once again projected by the second optical system; a sharpness state of the photolens is determined by using these light-sensitive elements to detect the relative spatial relationship of these object images projected once again. The sharpness-determining device comprises a beam-splitting device which is arranged in the second optical system and splits up a light bundle, coming from the exit pupil of the photolens, into a central section and an edge section. Using this arrangement, it is possible by means of the second optical system to obtain an object image which is required in accordance with the varying f-number of the exit pupil of the photolens, or an object image which simultaneously allows the use of a further determining process with this device.

Title: Telescopic antenna which can be retracted or extended by means of a DC motor
Inventor: ALF REINHARD ING GRAD
IPC: H01Q1/10
Filed: 1983-09-29
Abstract: A telescopic antenna is proposed which can be retracted or extended by means of a DC motor and in which it is possible to dispense with a blocking spring. Known telescopic antennas have, inter alia, a counting wheel for counting the revolutions of the motor shaft, which counting wheel is protected against inadvertent rotation by means of a blocking spring. The blocking spring causes ticking noises and, in the event of a fracture, prevents exact counting. The telescopic antenna according to the invention has a self-blocking counting mechanism as the counting mechanism (10). The counting mechanism has a counting wheel (13) with two switching bodies (16, 17) on the circumference. The switching bodies are arranged in such a manner that they operate two switches (30, 31) which are located between a pole changer (43) and the motor (51), in such a manner that the motor circuit is interrupted and prepared for the opposite rotation direction in the limit positions of the antenna telescope (59). <IMAGE>

IPC: B24B23/00
Filed: 1984-01-31
Abstract: The invention relates to a securing means for a dust bag which can be fitted on the discharge nozzle of a portable oscillating grinding machine which is equipped with dust extraction and is driven by an electric motor. The dust bag comprises a connecting piece, which can be combined with the discharge nozzle of the portable oscillating grinding machine and exhibits a collar-shaped part, and a clamping element which is resiliently compliant, cooperates with the collar-shaped part of the connecting piece and fits in a snap-in manner into a recess of said connecting piece. In the edge region of its opening, the dust bag is clamped fast between the collar-shaped shoulder of the connecting piece and the clamping element. It has been shown that fastening of the dust bag by clamping alone is insufficient. The dust bag has therefore been additionally fixed, in the region of the its clamping zone, by adhesive bonding to the securing parts. It is the object of the invention to provide a securing means which makes the additional operation of adhesively bonding the parts to be combined dispensable and, moreover, in any case ensures a reliable fastening of the dust bag on the securing means. This object is achieved according to the invention in that the resilient clamping element (4) is provided with pins (6), to which recesses (5), made in the collar-shaped shoulder (2) of the connecting piece (1), are assigned. On fixing the dust bag, the pins pierce its edge region and ... into the recesses in the ... Original abstract incomplete. <IMAGE>
