Title: Two=stroke reciprocating piston engine - has neighbouring pistons with toothed racks, which are connected by shaft with gear, to form working unit
Inventor: WERNER KURT DR ING
IPC: F02B75/02
Filed: 1992-07-17
Abstract: The engine is without crank mechanism, and has cylinders located in a row. Two pistons (3a,b) with connecting rods (4) are connected via the shaft (6) with carrier elements (7). The piston rods engage into a driven gear via a mechanical or magnet-hydraulic, electronically-controlled freewheel unit (8) with toothed gear.

Title: Dry process to filter incineration or smelting particles from smoke - uses additives, infrared detectors and extinguishing system to reduce fire risk preventing or minimising damage to filters
IPC: B01D46/44
Filed: 1992-08-17
Abstract: A dry process for the removal of dust from incinerator smoke or smelting plant uses a number of filters which may burn or be damaged by high temperatures. The novelty is that (a) large glowing solid particles are first removed from the flow of raw gases by a coarse separator; (b) one or more additives are introduced to the raw gases and reduce the combustion propensity of the remaining dust particles; (c) a spark recognition system automatically registers the presence of sparks and triggers fire extinguishers upstream of the filter; (d) a further spark recognition system is positioned in the filtered gas flow downstream from the filter; (e) the spark recognition system triggers action to recognise, localise, limit and extinguish fires within the relevant filter housing. USE/ADVANTAGE - The process is one of dry removal of combustible particles from incinerator or smelting plant smoke effluent. The process sharply reduces the incidence of damage and disruption due to filter fires and extinguishes fires as these occur.

Title: New engine, two-stroke, with wider piston extension and wider cylinder extension, engine driven by pure petrol and diesel
Inventor: FIRUS GUSTAV
IPC: F02B1/04
Filed: 1993-05-11
Abstract: New engine, two-stroke, with wider piston extension (1) and wider cylinder extension (2), is driven by pure petrol. Due to the large amount of fresh air, even when first starting, the two-stroke engine can also be used as diesel engine. The petrol is electronically injected into a chamber (8) mounted on the engine upstream of the cylinder (1) and is immediately injected with the last fresh air into the cylinder (1a) after combustion. Due to the petrol injection into each individual cylinder, the two-stroke engine runs on only one piston when idling, thanks to an electronic circuit breaker. The second piston draws in the fresh air, which passes back out to the exhaust (12). <IMAGE>
Patent DE-4321694-A1 (DE)
Title: Method for venting tanks
Inventor: DENZ HELMUT DIPL ING
IPC: F02M25/08
Filed: 1993-06-30
Abstract: The invention relates to a method for venting fuel tanks in motor vehicles which are equipped with internal combustion engines and whose tank venting systems are equipped with a sensor for the tank pressure. According to the invention, the signal of the pressure sensor is used to control the tank venting valve in such a way that the flow resistance of the tank venting valve is set by means of its opening state as a function of the signal of the pressure sensor in such a way that the flushing rate, that is to say the flow of gas volume through the tank venting valve is limited in such a way that the tank pressure does not drop below a prescribable pressure threshold. The tank venting valve thus acts to a certain degree as a controllable flow throttle in order to avoid critical underpressures.   <IMAGE>

Title: Control program for embroidery or knitting machine
IPC: D04B15/66
Filed: 1994-01-21
Abstract: The system to develop a control program. for an embroidery or knitting machine, has a matching unit which adapts the overlay of at least one pattern section over the ground section to match the edge transits. The specification is an addition to P4329875.3.  Pref. the matching unit also carries out the working at the reverse side of the material, and displays an image of the reverse side to match the pattern edge transit when the pattern is set by rows. It determines whether, after a given number of rows, whether a reverse side image is required. The matching unit, on establishing that the reverse side working end with the next row, registers whether in a given number of following rows, the reverse side will be taken up and therefore continues the rear side working. If the overlaid pattern does not start at the first stitch of a row, the pattern yarn is laid off from the last stitch of the pattern, away from the patterning area. The matching unit executes the side bonding of the overlaid pattern section on the ground pattern, using an intarsia stitching, or the location and/or type of bonding stitching can be selected.
