Title: Energy saving injection unit - comprises a low powered drive which moves and injection unit up to a tool while a short stroke high pressure cylinder retains it
Inventor: ACKERMANN WOLFGANG
IPC: B29C45/17
Filed: 1990-03-16
Abstract: An injection unit (A) for a plastics injection moulding machine is described and which replaces the large volume cylinder used for nozzle movement and retention of the nozzle against the tool. The movement of the injection unit and nozzle to the injection position is achieved by a low energy power source while a separate power source producing a higher force is used to retain the nozzle against the tool inlet. The power source for the higher load is arranged below the plasticizing unit and at an acute angle to the axis. The hydraulic cylinder used has only a short stroke. For an injection cycle the plasticizing unit moves forward over the cylinder and locates the nozzle against the tool. The cylinder is then supplied with pressure which forces the piston rod against an angled face below the plasticizing unit and hence the nozzle is retained under a high load against the tool. USE/ADVANTAGE - (A) is used in plastics injection machines and saves press energy by replacing the large volume, long stroke cylinder by a dual closure and clamping system.
Patent DE-4013842-A1 (DE)
Inventor: MAYER JOERG DIPL ING
IPC: H04N19/61
Filed: 1990-04-30
Abstract: In the process described, original images are divided for image-data transmission purposes into zones and, for each zone, transformation data prepared and/or motion vectors determined in accordance with a modification criterion. For transmission, transformation-coded data and/or motion vectors are determined, for every other original image, only for a few image zones in which significant modifications occur. In order to reconstruct the images at the reception end, interpolated images are created into which is inserted each image zone for which transformation-coded data and/or motion vectors were determined. The process described is particularly suitable for the transmission of camera images produced without a tripod, interference due to blocking signals or jerky movements being eliminated.

Patent DE-4110042-A1 (DE)
Inventor: RAPP MANFRED MAX
IPC: F02B53/00
Filed: 1991-03-27
Abstract: A piston engine designed as a motor with a star configuration has a rotary shaft arranged in the motor housing, upon which pistons linked to a piston rod are radially movable. An expanding gaseous fluid exerts a pressure on the pistons that are arranged each in a working chamber located in the motor housing. The successive working chambers and pistons generally have a wedge-shaped cross-section, and the number of working chambers and pistons is variable. The pistons are radially movable in the rotor, in the direction of rotation, and operationally coupled to a forced control. The object of this invention is to obtain a specific power as high as possible with a compact design and a reduced engine weight. Among many others, its most remarkable characteristic is the extremely high motor torque that results from this motor system. With this engine an engine torque that is 48 times higher than that of comparable 4-stroke internal combustion engines is obtained, thanks to the 24-fold reduction of the driving engine speed caused by the system and to the 2-stroke system. During each rotation of the rotor shaft 24 x 24 = 576 working cycles per engine disk are obtained. A comparable 20 cylinders 4-stroke reciprocating piston engine has only 10 working cycles during each rotation of the crankshaft.
