Title: Machine component exposed to sliding friction, such as, in particular, a piston ring
Inventor: PLANKERT HANS-WILHELM
IPC: F16J9/26
Filed: 1986-10-11
Abstract: A machine component exposed to sliding friction and having a wear-resistant coating on the sliding surface, such as, in particular, a piston ring for internal combustion engines with an electrodeposited hard chromium coating on the sliding surface, has depressions which are distributed in a grid pattern over the sliding surface and extend into the base material. If there is inadequate lubrication, effective oil reservoirs are formed in these depressions during operation. The holes are burnt into the base material before the application of the coating, preferably by laser, so that when deposition takes place holes also form in the coating material. Since the holes also extend into the base material, they remain functional even when the coating wears, and the risk of spalling is simultaneously eliminated. <IMAGE>

Filed: 1986-11-04
Abstract: Hydroelectric power plant with floating weir, cross-flow turbine and integrated rotary screen, characterised in that the retaining arrangement with integrated turbine-output regulating valve is arranged in the interior of the cross-flow turbine, a turbine housing is unnecessary, the turbine wheel is fully or partly immersed in the working medium and is mounted in a lattice structure which is supported on two floating bodies, of which the one arranged at the rear as viewed in the flow direction can be emptied by compressed air and flooded upon valve reversal. The front, rigid floating body, filled with foam material and guided on both sides in the channel, also serves as a floating beam. A turbine module consists of a split cylindrical rotor with output regulating valve, adjusted on a common axis as part of the retaining arrangement arranged in the wheel interior. Output regulation and disposal of floating debris are effected hydraulically, power transmission by means of toothed belt or the like. Rings arranged on the wheel periphery form a rotary screen which runs against fixed rakes. Auxiliary units are accommodated in a separate space. The bypass relief valve shuts tightly at the bottom in an angular range for the disposal of floating debris. The release of the full discharge cross-section at high water opens many new locations.

Title: Door-control device
Inventor: GEIGER HARTMUT DIPL ING
IPC: E05F15/50
Filed: 1986-11-15
Abstract: Known door-control devices have a separate emergency control device. The separate arrangement necessitates a high outlay and the risk of operating faults. The invention proposes, as an emergency control device, to integrate into the door-control device a mechanical actuating device (48) accessible from outside the door-control device. In one embodiment, the invention provides an actuator (1, 29) which executes a working function when displaced into one of two respective end positions, and the emergency function when displaced into an intermediate position. In another embodiment, each working function is assigned its own actuator (72, 81); in this case, both actuators (72, 81) are adjusted in order to execute the emergency function. The mechanical actuating device (48) is designed such that, in the former case, it sets the actuator (1, 29) into the intermediate position and, in the case mentioned second, sets the actuators (72, 81) into their positions guaranteeing the emergency function. A door-control device serves for controlling the opening and closing of a door actuated by a pressure medium and for stopping the door in the event of an emergency situation during a door movement. <IMAGE>

Patent DE-3742083-A1 (DE)
Title: Double-roll machine such as roll press
Inventor: STRASSER SIEGFRIED
IPC: B02C4/28
Filed: 1987-12-11
Abstract: In the pressing and/or comminution of granular material in a double-roll machine such as a roll press, the feed material in the roll gap is not grasped to the same degree and drawn into the roll gap by the edge zones of the rolls as in the central region of the roll gap. This not only has an adverse effect on the throughput capacity of the double-roll machine but leads above all to discharges of insufficiently pressed displaced material which must be separated from the finished material and returned in a closed circuit to the material feed chute of the roll machine. According to the invention, however, pressing and/or comminution, free of misplaced material, of granular material in the roll gap of a double-roll machine is achieved in that, inside the material feed chute (12), there is arranged a vertically adjustable slide (13) which projects from above into the latter and is intended for adapting the slope height (14, 19) of the mass of bulk material to the flowing properties of the latter, in particular in the edge region of the material feed chute. <IMAGE>

Patent DE-3825532-A1 (DE)
Inventor: HERBER RALPH DIPL ING
IPC: B65H51/10
Filed: 1988-07-27
Abstract: The invention relates to a wire gun with a feed device for the wire with a feed roller (2) for the wire driven by a d.c. motor (1) and a counter-roller (3) pressing the wire against the feed roller (2). The purpose of the invention is to provide such a wire gun in which, unlike the prior art, it is unnecessary to change or replace gears over the whole wire feed rate adjustment range. This purpose is attained by the invention in that successive drive voltage pulses of variable pulse width and/or frequency may be applied to the d.c. motor (1) to control the feed rate. This measure provides a sufficiently high torque to convey the wire even at very low feed rates, i.e. at low motor rotation speeds.

Abstract: The invention relates to a basket container which can be collapsed to form a very small bundle, is not provided with pressure closures, is made of plastic or light metal in a skeleton form, and serves, in particular, as a shape-adapting insert for shopping trolleys. This provides the user with the convenience of being able to convey the articles directly from the point of purchase or sale, that is to say without repacking them into bags, boxes, etc. To protect the articles located in the shopping basket from the influences of the weather and the like, a covering cloth which can be removed from a guide bar is mounted on one wall of the basket. The shopping basket made in two designs has different carrying devices, namely carrying handles or one displaceable carrying bar (handle). By three rows of hinges arranged in each case vertically on the end walls and connecting the side walls without corner closures, the shopping basket is unrestricted in the size and surface design of all wall parts and the bottom insert for the collapsing process. Operating the basket container, e.g. for the collapsing operation, takes place only after pulling up the bottom part and pushing down the carrying handles (large basket) or pushing in the carrying bar (small basket) by lightly pressing in the end walls.
