Abstract: The invention relates to a bandpass filter for electromagnetic radiation, which consists of a diaphragm which has slot structures arranged periodically. The invention has the object of designing a bandpass filter such that it has an optimum blocking characteristic. This is achieved in that the bandpass filter has a thickness of between 33 and 500  mu m and that the ratio of the thickness to the grid constant, which describes the periodicity, is greater than 1.

Abstract: With a webbing-insulator element in the anchoring of radio masts, having at least one insulator which is surrounded by an insulator bracket on two mutually opposite sides, on whose free ends connecting elements to the adjacent insulator element or to an end element are mounted in a hinged manner, it is intended to create a solution which permits simpler and more cost-effective manufacture. This is achieved in that the insulator bracket consists of a steel segment (1) having a turned-out contact surface (1a) for the insulator (7) around which a bracket lug (2) is welded on, on whose ends lugs (8), in each case on both sides, engage as a connecting element to the adjacent insulator element or end element.

Abstract: The invention relates to a body-felt sound unit having a vibration transmitting member (2) imbedded in a human body support member (8), for example, a chair, a bed, etc., and an electro-mechanical vibration transducer (4) attached to the vibration transmitting member (2), the transducer (4) generating mechanical vibration on receipt of a low-frequency current, thereby transmitting the vibration to the human body (9). The vibration transmitting member (2) comprises a flat plate- or net-shaped member (3) of a relatively large area, and the electro-mechanical vibration transducer (4) is attached to the vibration transmitting member (2) such that the direction of vibration generated from the transducer (4) coincides with the direction of the width of the vibration transmitting member (2) so as to transmit transverse vibration to the vibration transmitting member (2). Even if the vibration transmitting member (2) is thin, the apparent rigidity becomes high, so that the transmission of vibration is effectively made.

Abstract: For the forging of workpieces with a pronounced longitudinal axis, use is made of forging machines which are provided with three or more rams distributed in one plane, in particular with four rams offset relative to one another by 90 DEG  in an X shape, acting radially on the workpiece guided longitudinally along the axis of the system and fitted with tools. In order to achieve a compact construction of such forging machines and, at the same time, to achieve ram guides with little play, the rams are, according to EP 0 228 658 B1, designed as pistons or cylinders of piston-cylinder units and guided directly, i.e. not in staggered formation. Starting from this prior art, it is the object of the invention to avoid both double-acting pistons and ram retraction mechanisms acting by way of shafts. This object is achieved by virtue of the fact that, taking rams (2) designed as or connected to cylinders as a basis, the rams (2) or cylinders connected to them are, according to the invention, each provided with or connected to a flange (19) and each surrounded by a ring (17) which engages behind the flange (19), each ring (17) and the cross-beam (15) assigned to it and intended for stroke-position adjustment being connected and piston-cylinder units (22, 20) for the retraction of the rams (2) being arranged between each ring (17) and the associated flange (19). <IMAGE>

Abstract: A device for driving and controlling a variable reluctance motor in such a way that a mean voltage applied to an exciting coil varies in proportion to a current deviation or current command. When the current deviation or current command is positive or zero, a first transistor (Q1) is maintained in an ON state by a signal selecting circuit (13) which receives a PWM signal from a PWM circuit (11) fed with the output of an absolute value circuit (10), a polarity judging signal from a polarity judging circuit (12), and the output of a circuit (20) for generating an ON/OFF signal. While the output of the circuit (20) is at an H level a second transistor (Q2) is turned on or off according to the PWM signal, and positive and zero power supply voltage are generated alternately across a coil (L). Contrarily when the current deviation is negative, the second transistor is made to be in an OFF-state by the signal selecting circuit. While the output of the circuit (20) is at an H level, the first transistor is turned on or off according to an inverted PWM signal and negative and zero power supply voltage are generated alternately across the coil. After all, the driving circuit ON/OFF duty factor corresponding to the current deviation or current command and the voltage to be applied to the motor are maintained in a required correspondence relation. Thereby, the mean voltage across the coil varies in proportion to the current deviation or current command and the motor can be controlled suitably.

Abstract: In the case of known quadruple plate bearings, for height adjustment it is possible only with difficulty to reach and shift the spokes of the setting wheels of such a bearing, it being necessary either to insert a rod or the like through the gap between two plates or raise the plate to be levelled. In order to avoid raising the plate or shifting the setting wheel spokes by means of a rod inserted through a gap between two plates, the setting wheel is designed as a gear wheel (6) with which there meshes a second gear wheel (7), the shaft (19) of which has a receiving device for a setting key, which can be inserted through the gap (2b) between two plates. By virtue of its convenient and quick height adjustability, the plate bearing is suitable for supporting plate surfacings of terraces and similar areas covered with plates. <IMAGE>
