Title: Displacement-measuring device for working cylinders with pressure-medium-actuated thrust pistons in underground working
Inventor: CZAUDERNA NORBERT DIPL ING
IPC: E21D23/14
Filed: 1981-04-09
Abstract: The invention, in particular according to Figure 1, relates to a displacement-measuring device for pressure-medium-actuated working cylinders in underground working with the aid of several transducers, actuated as a function of the position of the thrust piston, and a circuit for analysing the transducer signals. For wear-free actuation of the transducers, provision is made for the transducers, which are designed as pressure transducers (27-31), along the length (a) of the working cylinder (3) traversed by the front and rear edge (19, 20) of the thrust piston (10) to be set to a pressure independent of the piston movement. A limit control is allocated to this pressure in the analysing circuit. The limit control determines the displacement direction from the time intervals (t1-t5) and the sequence of the transducer signals (32, 33) and determines the displacement length of the working cylinder or the thrust piston from the addition. <IMAGE>

Title: Brush power supply for electrical machines and apparatuses
Inventor: SCKERL WALTER
IPC: H01R39/58
Filed: 1981-01-23
Abstract: Both brushes and sliding elements, especially those made of synthetic carbon, frequently wear at an uneven rate. It is therefore not sufficient to replace them after a specific operating time, and measures must be taken to prevent damage being caused to the opposing contact as a result of premature wear. For this purpose, it is proposed to equip the brush holders or the power take-offs with two signalling contacts which are insulated both from one another and from the brush holder or the power take-off. These signalling contacts are short-circuited or open-circuited by metallic parts on the pressure element, as a function of the wear state of the brushes or of the sliding element, depending on the method of switching of an associated signalling circuit. <IMAGE>

Title: Use of a copper alloy
Inventor: BECKER HANS-JUERGEN
IPC: B23K35/22
Filed: 1981-09-29
Abstract: In resistance welding of aluminium or aluminium-alloy components, considerable problems arise because aluminium alloys onto the contact surface of the welding electrodes and the electrodes adhere to the workpieces. The previous attempts to overcome these difficulties have not been a total success. Surprisingly, it has been found that a substantial improvement can be achieved by using a copper alloy containing more than 0.3 to 1.5% oxygen and 0.2 to 1.0% silver and/or 0.2 to 0.5% nickel, the remainder being copper, including normal, unavoidable impurities, to produce the electrodes.

Title: Device for supporting and levelling a caravan or the like
Inventor: NESSELBERGER WOLFGANG
IPC: B60S9/06
Filed: 1981-11-04
Abstract: In a device for supporting and levelling a caravan having a plurality of sustainers which are attached under the floor of the caravan and can be extended towards the surface of the ground, the support and levelling process is to be simplified. For this purpose, each sustainer is coupled to a controllable drive element, namely a geared motor. A spatial position signal generator which aligns itself automatically and which always sets itself at the centrepoint of the ground without pre-adjustment, is attached to the caravan and connected to each drive element via a control device. The control device controls the drive elements for supporting and levelling in such a way that the drive elements are initially moved as far as the surface of the ground independently of the spatial position signal generator. Subsequently, the spatial position signal generator is actuated and the drive elements are successively actuated for a period of time until the caravan is exactly aligned. <IMAGE>

Patent DE-3149184-A1 (DE)
Title: Vehicle with foot drive
Inventor: MEYER BRUNO
IPC: B62M1/24
Filed: 1981-12-11
Abstract: A single-track or multi-track vehicle has a foot drive which is composed of two pedal levers (4) which are arranged above the front wheel, are mounted pivotably and are alternately operable. Via tensile members (8), the force of the pedal levers (4) is transmitted to free-wheel drums (9, 9') which cooperate with a conventional chain drive with driving sprocket (12), chain (53) and rear-wheel sprocket (13). The tensile members for the two pedal levers are preferably connected to one another at their rear end and guided by a deflection pulley (11). By operating the pedal levers (4) simultaneously, the deflection pulley (11), which is pushed by spring force (14) into its one end position, is pulled out of this end position and, as a result, vehicle brakes (17, 18) can be operated. The saddle of the vehicle has a backrest (59) on which the pelvis of the rider is supported so that between thighs and lower legs and the backrest (59) and the pedals (6) a toggle effect is obtained which results in an optimum utilisation of force. The points of application of force of the tensile members (8) on the pedal levers (4) can be infinitely adjusted during the journey and, as a result, the lever arm effecting the drive in each case can be infinitely adjusted. To this end, the pedal levers (4) are preferably of circular design so that when the point of application of force of the tensile members is displaced, no change in length of the tensile members is required. In addition, an electric auxiliary motor can be provided. <IMAGE>

Patent DE-3214080-A1 (DE)
Title: Device for reproduction of stereophonic, in particular head-related signals
Inventor: THEILE GUENTHER DR ING
IPC: H04R5/033
Filed: 1982-04-16
Abstract: In the reproduction device according to the invention, two loudspeakers are disposed diagonally in front of the auricles of the listener, at a distance, in order to improve forward location. To ensure that the location of the listening event remains unchanged in relation to the body of the listener, even when the latter turns his head, the two loudspeakers are attached to a bracket supported on the neck and body of the listener. Interaural ear signal differences are thus produced when the head is turned, such as those occurring when the head is turned in the original sound field. In this way, every movement of the head of the listener performed for sound location purposes supports his forward location.

Patent DE-3219221-A1 (DE)
Title: Method and device for automatically adapting the adjustable dead zone of a nonlinear transmission element to the amplitude of a noise signal superimposed on its input signal
Inventor: EWE KURT
IPC: G05B11/18
Filed: 1982-05-21
Abstract: In a nonlinear transmission element having an adjustable dead zone, the latter is adapted to the amplitude of a noise signal superimposed on its input signal, in that the dead zone is rapidly increased by a certain amount in a cyclic sequence and is then slowly decreased again, in dependence on three output signals of alternating polarity which follow one another within a time interval dependent on the duration of the period of the noise signal. If a further output signal of the nonlinear transmission element occurs with a polarity which is opposite to the preceding one, following a switching step increasing the dead zone, a further switching step increasing the dead zone is immediately initiated. When the noise amplitude suddenly and strongly increases, this reduces the switching frequency of the output signal. This is of significance when the nonlinear transmission element is a part of a controller with switching-type output which operates into an integral-action control element. <IMAGE>

Patent DE-3240907-A1 (DE)
Inventor: PFANNENSTIEL HUBERT
IPC: B22C7/02
Filed: 1982-11-05
Abstract: A method of making individual castings. In the production of individual castings, in particular in dental engineering, the casting is usually premodeled in wax. However, this casting model is very susceptible to deformation, which leads to inaccuracies in the fit of the casting. With the present method, at least a part of the casting model is built up from a photopolymerizable compound which burns leaving no residue. Advantageously, the curing is carried out, in the presence of a suitable initiator, with visible light; the basis of the compound is a photopolymerizable (meth)acrylic acid ester. In dental engineering, with the present method there is made possible in a simple manner to build up form-stable casting models for making crowns, bridges, and inlays and, particularly favorably, complicated secondary parts for removable dental appliances.
