Title: Cold reciprocating rolling - uses lengths of wire feed in multiples of workpiece length with tubular material guide to prevent kinking
Inventor: STINNERTZ HORST ING GRAD
IPC: B21B21/06
Filed: 1991-01-21
Abstract: For cold reciprocating rolling action to shape wire material into a workpiece, with a different cross section along its length, the wire material (7) is prepared as a multiple lengths of the length dimensions of the workpiece. They are fed to the roller stand (10) by a rotating/advance mechanism (9) with a tubular guide (11) for the material (7), with little free play, between it and the roller stand (10). At the end of the rolling stage, the rotating/advance mechanism (9) together with the tubular guide (10) are retracted by an amount which is at least equal to the workpiece length. A cutter (12) at the far end of the roller stand (10) severs any wire feed material (7) still connected to the retracted workpiece. The tubular guide (11) is retracted by a greater distance than the retraction for the rotating/advance mechanism (9). The feed (9) has a roller set in friction contact with the wire feed material (7), rotating in a housing round the material, using rollers angled against the wire axis. The wire feed material is wound into a coil (6) on an axis parallel to the rolling line, or at a slight angle to it. ADVANTAGE - The appts. can use wire feed material, in lengths as a multiple of the length of the finished workpiece, without kinks while the workpiece is rolled.

Title: Starting device for Diesel engine - uses electromagnetic relay to admit compressed air to cylinder for regulator rod piston
Inventor: KOTAUCZEK FRITZ
IPC: F02D11/04
Filed: 1991-03-22
Abstract: The control lever (8) for the fuel injector regulator is positioned by a rod (7) whose piston (6) moves in a pressure cylinder (4), against a spring. The cylinder is connected to the accelerator pedal. A pipe (9) can convey compressed air from reservoir (10) to the engine side of the piston, when a valve (12) is activated by the electromagnetic relay (16). The relay is active for a fixed time (say 2 seconds) after starting, and thus for this time, the effective stroke of the rod (7) is shorter because the piston is forced towards the end of the cylinder against the spring. This position admits the correct fuel quantity for hot-starting. USE/ADVANTAGE - Starting device for compression ignition engines in commercial vehicles; prevents fuel flooding when engine is hot.

Title: Automatic bottle washing machine with continuous drive - has nozzle slide with reciprocating motion allowing nozzles to enter bottles on continuously driven conveyor chain
Inventor: SILBERZAHN HELMUT
IPC: B08B9/32
Filed: 1991-03-31
Abstract: The automatic bottle washing machine has a continuously driven endless conveyor chain on which are mounted elongated baskets each holding a row of bottles to be transported through the stages of a cleaning process including internal spraying. At the internal spraying station is a nozzle slide (24) which moves up and down in a guide frame (23) which itself is driven backwards and forwards in the line of motion of the conveyor chain. The two motions of the nozzle slide are synchronized with the conveyor chain motion by cam and follower mechanisms driven from the conveyor drive shaft, enabling the nozzles to enter the bottle necks, to spray the inside and to withdraw without relative movement.The nozzle slide has two rows of nozzles, allowing engagement with two adjacent baskets per spraying cycle. ADVANTAGE - Reduced energy consumption machine wear.

Inventor: JAKOB HARALD DR
IPC: C07C229/12
Filed: 1991-04-12
Abstract: The preparation of L-carnitine by racemate resolution of D,L-carnitine nitrile salts, in particular D,L-carnitine nitrile chloride, using optically active resolving reagent, resolution of the diastereomers, conversion of the diastereomer containing L-carnitine nitrile into a salt of an acid which is not optically active and hydrolysis of the L-carnitine nitrile salt can be successfully carried out in high yield and high enantiomerical purity when N-acetyl-L-proline is used as the resolving reagent. The (L,L)-diastereomer is separated from the diastereomer mixture in crystalline form, which avoids a second, fractional crystallisation step, which was hitherto customary.

Patent DE-4122704-A1 (DE)
Inventor: HENDEL HORST DIPL ING
IPC: H01H50/56
Filed: 1991-07-09
Abstract: The relay has a basic body (100) with a bearing pin secured in its wall or base which protrudes perpendicularly from the wall. A contact spring (108) made of strip material is taken partly around the bearer pin with a securing section in the form of a clamping sleeve (181). Besides a spring shank (182) it forms on the other side of the securing section a prestressing shank (183) supported on a supporting component, preferably a coil flange (102) and thus prestresses the spring shank in its position of rest. The contact spring can also be fitted in cramped and poorly accessible positions, e.g. between the coil and the armature and given a predetermined prestress without its having to be soldered to the bearer pin or subsequently adjusted.

Title: Detecting position of printing plates in printing plate measurement device - involves line wire measurement of pixels along plate edges to detect intensity step, measurement location coordinate storage and processing
Inventor: BRAUNER RALPH
IPC: B41F33/00
Filed: 1991-07-11
Abstract: The method of measuring the position of a printing plate involves detecting the plate edges.

The process is repeated at least twice along the left and right edges of the plate. The top and bottom edges of the plate are detected by at least two linewise measurements of pixels over each breadth of defined plate columns and the measurement point coordinates stored. The measured edge values are compared to determine the position and at least two corner coordinates. USE/ADVANTAGE - For measuring position of printing plate before plate itself is measured. Accurate measurement of plate edge positions.

Filed: 1992-04-22
Abstract: The present invention relates to a honeycomb structure (10) of electrically conductive material which is electrically divided by slots (13, 14) and/or electrically insulating layers in such a way that an electric current can flow along a winding path (17) through the structure (10). The honeycomb structure (10) has a region (18) of a material with a higher specific electrical resistance. The honeycomb structure (10) is preferably cylindrical or an oval cylinder with roughly axial slots (13, 14) which extend, slightly offset, from the outside to an end (19) inside the honeycomb structure (10) and in which the internal cross-sectional region (18) of the honeycomb structure (10), which comprises at least all the ends (19) of the slots (13, 14), consists of a material with a higher specific resistance than in its outer cross-sectional region. This design facilitates a more uniform current density distribution in the honeycomb structure and prevents hot spots. Particularly when used as electrically heatable catalytic converters for motor vehicles, this makes for greater stability and longer useful life.
