Filed: 1981-01-22
Abstract: The reflector is for electromagnetic waves, and can turn one quarter of the polarisation direction in the reflected waves, and at the same time within two widely differing frequency bands, such as those with frequencies in the proportion of 4 to 1. For polarisation turning, two wire grids comprising parallel metal wires are placed parallel to a metal reflector's surface, and at different distances from it. Both wire grids are encased by a layer of dielectric material and the same material is between the reflector's surface and the grids. The distance from each of the grids to the surface of the metal reflector is in a ratio between 0.11 and 0.13, the distance being calculated in wavelength in the dielectric material. A cassegrain type aerial with a main reflector and one secondary is used for electromagnetic wave transmission and reception within the two very different frequency bands.

Abstract: The percussion device is intended for use in various branches of construction such as, for example, compaction of soils in confined conditions, destruction of concrete and bitumen-concrete pavements, stone blocks, loosening of solid and hard-frozen earth. The percussion device is provided with a casing (1), in the inner space of which a housing (2) with radial passages (32, 35, 36, 42, 45, 48) is accommodated while being enabled to move in a reciprocating manner. Mounted in the casing (1) is a working tool (23), the shank (22) of which is guided into the stroke volume of the housing (2). Accommodated in the stroke volume of the housing (2) of stepped configuration is a percussion piston (11), likewise of stepped shape and having sections of larger diameter (14) and smaller diameter (12, 13), which forms with the housing (2) three stroke volumes (18, 19, 20). The stroke volume (18) is used for filling with pressure gas and here appears as a pressure-gas accumulator. The stroke volume (19) communicates with the hydraulic discharge line (33) via the passage (32). The stroke volume (20) is connected by the radial passages (35, 36) to the hydraulic pressure line (34). The intermediate distance between the radial passages (32 and 35) in the housing (2), which are connected to the hydraulic pressure and discharge line (4' and 5'), can be divided by the maximum intermediate distance between the working tool (23) and the percussion piston (11). A stem (21) movable in the axial direction is accommodated coaxially to the working tool (23) in the housing (2), one end projecting into the stroke volume (18) and the other end interacting with the casing (1) to transmit a force to the casing (1) from the pressure-gas accumulator. In order to bring about its automatic mode of operation, the percussion device is equipped with a hydraulic distributor (7) which has accommodated in the cylindrical inner space (38) of its housing (37) a slide (46) which separates this cylindrical inner space into two sections (40 and 41). One section (40) of the cylindrical inner space is constantly connected to the stroke volume (19) by a radial passage (45) of the housing (2). The other section (41) of the cylindrical inner space of the hydraulic distributor (7) communicates via a radial passage (48) with an annular recess (15) on the percussion piston (11). Made in the circumferential surface of the hydraulic distributor is a bore (39) which is covered in alternating manner by the slide (46) and is connected via the radial passage (42) in the housing (2) to the stroke volume (20) communicating with the hydraulic pressure line (34). <IMAGE>

Abstract: In a pane guide for a sliding window capable of being lowered into the window shaft (8) of an automobile, the windowpane (1) is laterally guided on windowframe components (4,5), in which back-cut guide channels (18,18') are provided, in which slide elements (23,23') are displaceably guided. The slide elements are connected with the windowpane (1), covering the windowframe components on the outer side of the vehicle, by carrier elements (19 to 22). Due to the mounting of the windowpane outside the windowframe, a projectionless lateral glazing of an automobile is made possible. At the lower end of at least one of the lateral windowframe components (4,5), the guide tube (11, 11') of a cable/tube window winder is connected in alignment with the guide channel (18, 18'). The threaded cable (12, 12') of the window winder extends into the guide channel (18, 18') and is fixed at least to one of the slide elements (19 to 22) situated therein. In this manner a low overall height of the windowshaft is achieved, so that the windowpane and the window shaft can have approximately the same height. With the windowpane (1) is associated a seal (46) disposed on the windowframe (4 to 7), which seal is either continually in sealing contact with the windowpane or, by a movable mounting of the seal or of the windowpane, is arranged so that it can be pressed automatically onto the windowpane (1).

Abstract: An actuator has a rotor with permanently magnetized North and South poles. A housing supports three pole members having respective coils and pole pieces. The first pole piece is always a North pole but the coils on the second and third pole pieces are arranged such that each can be of either polarity with the other simultaneously being of the opposite polarity. The rotor therefore has two stable positions, one when the second pole piece is a North pole and the third pole piece is a South pole and the other being 120 DEG  from this position in the clockwise direction (when the second pole piece is a South pole and the third pole piece is a North pole). The rotor movement may however be stopped 15 DEG  short of each such position by mechanical detents, so as to limit the maximum angular movement to 90 DEG . The actuator may be used to drive a switchable microwave coupling arrangement.
