Title: Fibre material shearing machine with adjustable cutter beam alignment - has cutter beam guided at each end by rollers mounted on rotatable eccentric pins
Inventor: EHINGER ADOLF
IPC: B26D1/08
Filed: 1991-05-14
Abstract: The machine has a cutter beam (15) guided in inclined slots (14) of side pillars (11.1, 11.2) and driven up and down by a connecting rod (18). At each end of the beam are guide rollers (16) which engage in the slots (14) and are mounted on eccentric pins (17) seated in the beam. Fine adjustment of the height of each end of the beam from the work table can be achieved by rotation of the eccentric pins. The eccentric pin has gear teeth (20) engaging a rack (21) which can be driven by a leadscrew and nut (23). USE/ADVANTAGE - Beam alignment can be precisely adjusted without adjustment to machine drive.
Patent DE-4116318-A1 (DE)
Title: Protection circuit for accumulator against excessive discharge - uses three MOS transistors and potential dividers to block load current when battery voltage falls to low
Inventor: KRAUSE PETER DIPL ING
IPC: H02H7/18
Filed: 1991-05-15
Abstract: The load (RL) is supplied from the accumulator (G1) via a pair of MOS transistors (1) whose gates are connected at point (y) on a potential dividing network (R8, R9, 10) across accumulator terminals. This connection is also in series with the source-drain circuit of a third MOS transistor (V4) whose gate is connected at point (x) of a second potential dividing network (R3, R4, R5). The potential dividers are such that MOS-pair (1) is normally conducting, and V4 is blocked. The MOS pair (1) are N-channel enriched, V4 is N-channel depleted. As the load discharges, the accumulator voltage falls, and thus the voltages at points x and y. When the voltage at point x falls below one volt, V4 starts to conduct, thus reducing the voltage at point y significantly, thus turning the MOS pair off and preventing flow of load current. ADVANTAGE - Inexpensive battery protection requiring low extra current without special dedicated current supply.

Title: Container filling method e.g. with corrosive detergents - has various sensors allowing filling only if container is of permitted size and automatic shut-off when full
Inventor: MEESE HELMUT
IPC: B67D7/34
Filed: 1991-09-14
Abstract: The method involves placing the container on a shelf within a cabinet above the reservoir but below the delivery nozzle. Various sensors positioned around the container shelf detect the container shape and size, and if it is of the recommended style, the sensors permit the switching on of the delivery pump. The valve in the delivery head will open when a preset fluid pressure is reached. Another sensor detects the fluid level within the container and switches the pump off when the "full" level is reached. ADVANTAGE - Prevents use of unsuitable containers; automatic shut-off when full prevents dangerous fluid spillage.

Title: Internal combustion engine
Inventor: STREIT WERNER
IPC: F02B55/00
Filed: 1993-06-21
Abstract: The internal combustion engine has, in the interior of its casing, where, by the compression of compressed air and, upon combustion by means of an ignition process, the heat is converted into mechanical energy,   a rotor comprising an open ring and a solid annular disc, the latter being seated on the input shaft, with movable blade plates and a guide pin mounted between the ring and the disc, and a centrically, symmetrically formed stator mounted on the primary shaft, and firmly connected to the casing, which divides the interior of the housing into two volumes of equal size. During the rotation of the rotor around the stator, the blade plates are pressed in a sealing manner against the stator by a guide pin by way of a groove around the stator, crescent-shaped chambers of varying volume and having an intake, compression, combustion and outflow function being formed.   The division of the casing into two by means of the stator gives rise to two independent process sequences when the rotor rotates giving a quadruple compression operation (compressed air) with ignition and expansion of the combustion gas (heat) per revolution. Offset inlet openings act as a mixture chamber with precompression in the intake region. Technical object: increase in power in combination with cleaner compression and combustion. Solution: periodic chamber filling (air, mixtures) by means of the simplest possible compression technology (rotor-stator) leads to continuous (quadruple) energy conversion. Area of application: energy producing and consuming industry. <IMAGE>
