Title: Gravity operated rotary engine - has pistons in radial cylinders in vertical wheel, displaced by working fluid to produce torque by power difference
Inventor: RAHLENBECK ROLF
IPC: F03G3/00
Filed: 1980-07-24
Abstract: The engine has a vertical wheel with a large number of radial cylinders (4). Each cylinder contains a free piston (5,6). A working fluid is admitted from the centre of the wheel into the cylinders on one side of a vertical diameter of the wheel and released from the cylinders on the other side. It forces the pistons (5) on one side radially out, while those (6) on the other side are drawn in. This results in an unbalanced moment which causes the wheel to revolve. The working fluid can be subjected to differences of temperature, pressure, or electric potential, which are then converted weight differences.

IPC: H04N13/30
Filed: 1981-08-28
Abstract: The invention relates to a stereoscopic device consisting of a housing, in the front wall of which two viewing stubs equipped with optics are arranged, if necessary, and the rear wall of which serves as picture carrier. The invention is based on the object of developing such a stereoscopic device for viewing television displays of any type so that the viewer, who is located within arbitrary living or exhibition rooms can enjoy a stereoscopic television reception independently of the illumination conditions of the room. This object is achieved by the fact that in the area of the rear wall, two television sets, the screens of which have the lateral spacing required for the stereoscopic viewing, are arranged. The device according to the invention is in every respect compatible with regard to the existing television broadcasting systems. It is only necessary to transmit the supplementary stereoscopic picture for the "normal picture" already radiated in any case, on an adjacent channel, and to adjust the second television set to the reception of the stereoscopic supplement. <IMAGE>

Title: Pulse generator
Inventor: HORN HANS-JOACHIM
IPC: H01H1/18
Filed: 1981-09-15
Abstract: There is a pulse generator for generating individual up-and-down-counting pulses for setting or correcting an electronic digital display, in which a reciprocally movable control member (1) is provided with a row of cams (2) which deflectingly and releasingly controls a spring (6) in both directions of movement, which spring carries a movable operating member (10), and in which generator two pulse-emitting electrical circuits (11, 19) are provided which are in each case provided with a power source (12) and in each case exhibit a stationary operating member (9). In this connection, it is desirable if the construction of the pulse generator is simplified by dispensing with an additional spring element and an additional device for counting up and down. This is achieved in that the rest position of the spring (6) and of the moving operating member (10) is between the two stationary operating members (9) of the pulse-emitting electrical circuits (11, 13), the spring (6) with the moving operating member (10) is allocated to both pulse-emitting circuits (11, 13) and the direction of movement of the moving operating member (10) and the row of cams (2) are equal to one another in the area of the stationary operating members (9). In this arrangement, either only one circuit (13) outputs an up-counting pulse (V), or only the other circuit (11) outputs a down-counting pulse (R), with each operation. <IMAGE>

Title: Device for forming a stack of sheet-like blanks
Inventor: JUCKER HANS DIPL ING
IPC: B65H29/50
Filed: 1981-10-29
Abstract: The invention relates to a delivery device, for example on cutting machines, for the automatic ordered depositing of imbricated continuously entering sheet-like blanks of specific rigidity trimmed on all sides onto plane bases of fixed location. It affords a possibility of stacking blanks of paperboard, cardboard and the like in a simple and functionally reliable way, of avoiding preparatory work involving a high outlay at the place of installation of the device of and enhancing the quality of the stack, above all in terms of stability. For this, a principle known per se for the formation of a stack column between conveyor rollers on the exit side of a conveyor apparatus and a stop plate is extended in that the conveyor rollers on the exit side are guided straight not only vertically, but, for transfer before a renewed formation of a stack column, also horizontally. The object is achieved in that the conveyor axle on the exit side is guided in horizontal guide tracks on both sides and is connected to gearwheels in engagement with racks which are fastened to the horizontal guide tracks. Slipped onto the conveyor axle is a worm gear which has a self-locking effect and via the input shaft of which a rotational movement can be introduced. The system of a horizontal guide track, rack and conveyor axle on the exit side is also guided straight in a vertical guide track. <IMAGE>
