Title: Piezoelectric sound pickup for string instruments, and use thereof
Inventor: MARINIC JOSIP
IPC: G10H3/18
Filed: 1981-01-08
Abstract: Piezoelectric sound pickups for string instruments, particularly for guitars, and use thereof. In a cross-sectionally approximately U-shaped electrically conductive trough-like crystal pickup housing (15) used as shielding mass, the prismatic piezoelectric crystals (17) are arranged at a distance from one another in the longitudinal direction of the housing (15). The metallised base and cover areas (17a, 17b) of the crystals (17) have opposite polarity and are in each case electrically conductively connected to upper and lower signal output conductors (22, 18) for in each case one of the two polarities. Pressure transfer bodies (K) are in friction-locked engagement in each case with the cover areas (17b) of the crystals (17), on the one hand, and the strings (13), on the other hand. The lower signal output conductors are constructed as metallic base strip (18), which is held insulated on the bottom wall (151) of the housing (15) with interposition of an insulating layer (23) on the underside and at the top of which (18b), the crystals (17) rest with their base areas (17a), making contact. The upper signal output conductors are formed by the fact that metallic blocks (22) are guided with their side faces with close fit in a contact-making manner at the housing sidewalls (152) as base part of the pressure transfer bodies (K) and rest with contact areas (k2) on their underside (22') in a contact-making manner against the crystal cover areas (17b). Within a connecting space (160) of the housing (15), the cable core of the positive feedline can be conducted through in an insulated manner from below through a housing bottom hole (25) and connected to a part (180) of the base strip (18), which protrudes into the connecting space, the negative or earth feedline being conductible to the housing and connectable to it as cable shielding jacket. <IMAGE>

Title: Proximity fuze for detecting metallic targets
Inventor: PLATZ WILLI DR DIPL PHYS
IPC: F42C13/08
Filed: 1981-02-19
Abstract: The invention relates to a proximity fuze for detecting metallic targets. The proximity fuze has a bridge circuit (2) consisting of a search coil (L1), a reference coil (L2), a fixed resistor (R1), as well as a fixed resistor (R2) and a controllable resistor (FET), in each case in one arm of a bridge. The bridge circuit is supplied using an AC generator (U). The output signals from the bridge are supplied to a differential amplifier (3) whose output signal is superimposed, in a selective filter (4), on the AC voltage signal (which is matched in terms of amplitude) of the AC generator (U). After low-pass filtering, the output signal of the selective filter is fed back via a timer (8) to the control input of the controllable resistor (FET). The proximity fuze does not emit an output signal to a detonating circuit (7) until the inductance of the search coil (L1) is changed quickly by a moving metallic target in the vicinity of the fuze. <IMAGE>

Title: Hydraulic drive with proportional valves controlling the feed and discharge
Inventor: ERTLER WERNER
IPC: G05D3/20
Filed: 1981-03-19
Abstract: The invention relates to a hydraulic drive with proportional valves controlling the feed and discharge, in which a volume sensor with a pair of round gearwheels as measurement mechanism is arranged in at least one working conduit of the drive. The tooth movements of the gearwheels are sensed in contactless fashion by means of detectors. Electric pulses are emitted in each case for discrete partial quantities corresponding to the geometrical tooth volume. Also provided is an electronic control system which is provided with a pulse counter and via which the proportional valves are controllable as a function of the number of pulses and/or pulse frequency. With the hydraulic drive, motion sequences with an acceleration ramp and a deceleration ramp are performed. Contactless control of the beginning of the deceleration ramp is effected. For this purpose, a number of pulses corresponding to the oil volume to be fed into the drive during the descent of the deceleration ramp as a function of the working speed and the angle of the deceleration ramp is added in the counter of the electronic system to the actual number of pulses emitted by the volume sensor. That is to say, a preliminary addition of the number of pulses corresponding to this quantity of oil is effected. After the number of pulses corresponding to the total travel has been reached, the drive is switched over to deceleration. The deceleration ramp is then traversed under the control of the proportional valve as a function of the angle of the deceleration ramp. <IMAGE>

Title: Arrangement of torsion bars on tiltable driver's cabs of commercial vehicles
Inventor: LINKELMANN NORBERT
IPC: B62D33/08
Filed: 1981-05-06
Abstract: The invention relates to the field of motor-vehicle technology. The aim of the invention is to achieve a wide tilting angle of the driver's cab of commercial vehicles by using long, resilient torsion bars. The object of the invention consists in being able to use long torsion bars even with restricted installation space and in the process to make an additional bearing bracket for the torsion-bar ends unnecessary. The essence of the invention consists in that the torsion-bar ends are arranged very close to the swivel axis (3) of the driver's cab (1). The torsion bars (7) are passed through the inner web (9) of the frame-side bearing block (4) and are inserted positively and non-positively in the outer web (10) of the frame-side bearing block (4). The torsion-bar ends are arranged on the outer web (10) of the frame-side bearing block (4) such that they are freely supported in the longitudinal direction. The invention can be used in devices for tilting driver's cabs on commercial vehicles. <IMAGE>
Patent DE-3122133-A1 (DE)
Title: Mirrors with image elements, ornaments, text or the like and method for producing such mirrors
Inventor: SEIDL HERMANN J
IPC: B44F1/04
Filed: 1981-06-04
Abstract: In the production of mirrors with image elements, ornaments, text or the like applied to the mirror glass, the pattern of the image is formed on the mirror by means of a pressure and/or covering method and recesses are formed, in dependence on the patterns of the images, on the sheet of glass forming the mirror, before the reflective coating is applied. These recesses either represent the pattern of the image themselves, because this surface is dull, or, however, the said recesses receive a coloured coating, the thickness of which is less than the depth of the recesses, so that the image elements of the image pattern do not project beyond the original glass surface. This prevents scratching of the image elements, but it also makes time-consuming and expensive drying of the coloured coating unnecessary in particular.

Title: Process for the cleaning of rolls or the like in an automatic film developer apparatus, and cleaning sheets for this purpose
Inventor: TANIGUCHI HIROSHI
IPC: G03D3/00
Filed: 1981-06-13
Abstract: A process for cleaning a plurality of rolls or the like in a treatment bath of an automatic film developer apparatus is described. In the film developer apparatuses of this type, an exposed film is developed while it is passed over a plurality of rolls or the like. The rolls or the like are now cleaned by passing a cleaning sheet, instead of the film, over the rolls or the like. During this operation, the substances adhering to the rolls or the like are transferred onto the cleaning sheet. The cleaning sheet ejected from the treatment bath can be returned to the treatment bath. The cleaning sheet has a length which is less than the total length of the circulation path, but is greater than the distance between the two adjacent rolls which are furthest apart from one another. It comprises a sponge sheet or the like. The rolls can be kept clean in a simple manner by periodically circulating the cleaning sheet through the apparatus. <IMAGE>

Patent DE-3129610-A1 (DE)
Title: Control circuit for actuators
Inventor: FREYTAG ADOLF
IPC: F02D41/20
Filed: 1981-07-28
Abstract: A control circuit for actuators is proposed which first supplies via an electronic switch (12) a constant control voltage which is lower than the supply voltage. The current, rising due to this control voltage, is detected in a current limit value switch (15) preferably constructed as comparator. If a limit value (Sa) is reached, the constant control voltage is switched off and the electronic switch (12) is now supplied by means of a clocked control voltage which preferably exhibits a supply-voltage-dependent duty ratio. As a result, reproducible conditions are obtained during the switching-on process even when the supply voltage fluctuates, and the control output stage (12) only operates in the active range during the switching-on process. <IMAGE>
