Title: Vehicular antilock braking control responsive to transverse acceleration - deactivating select-low regulation mode in extremely unstable conditions with substitution of individual rear wheel control
Inventor: MATSUDA TOSHIRO
IPC: B60T8/58
Filed: 1992-05-13
Abstract: Four wheel rotational speed sensors (31) are connected through a select-high switch (33) to a pseudo-road-speed calculator (34) whose output is thresholded (36) to obtain a common set-point (S) for the brake fluid pressure controller (37).

Title: H-F welding press for two three=dimensional films - welds them between electrodes positioned inside metal box and automatically earths screens to box when assembly enters it
Inventor: LIESER KAI
IPC: B29C65/04
Filed: 1992-05-20
Abstract: A h/f welding press bonds films with electrodes of the required shape, one of them being moved to and from the material to be welded. To bond together at least two three-dimensional films with a dense seam a forming tool inside a box is shaped internally to the form of outer surface required in the welded product; the films are positioned accurately each side of the welding plane in the forming tool; the h/f electrode has a strip with at least a two-dimensional bend and is attached to a metal plate which matches the shape of the weld. This strip has a flat backing electrode which is also shaped to match the weld seam and which grips the edge of the films against the strip in a gap in the plane of the weld; the gap concerned can be reduced to a set degree by evacuating a space by the two metal plates before or while applying h/f, and this increases the penetration of the electrode strip into the films; a pressure tool is connected to the earthed outside conductor round the h/f cable and has a screen which meets the metal box when the metal plate plus strip enter the forming tool; at the same time the electrode strip on the metal plate plus the backing electrode are brought into the screened area. ADVANTAGE - The layout of the electrodes produces high grade three dimensional welds between films at reasonable cost.

Inventor: STANKEWITZ HANS-WERNER
IPC: G02B21/06
Filed: 1992-09-18
Abstract: Described is a direct-light illumination system for microscopes, the system including a direct-light illumination module (18) comprising a Smith divider with an integrated telesystem (14). The telesystem (14) corrects, in the same way as "image shift" optics, length differences which occur on changing from a modular-design 45 DEG  neutral divider (20) to a module (18) fitted with a Smith divider. The two lenses making up the telesystem (14) are positioned in such a way that the convergent lens (15) faces the mirror (4) of the Smith divider and the divergent lens (16) faces the light source (6). Alternatively, it is possible, when changing a module with a Smith divider for a module (19) with a 45 DEG  neutral divider (20), to use with it a telesystem with the lenses positioned in the opposite order, so that the divergent lens (16) faces the 45 DEG  neutral divider (20) and the convergent lens (15) faces the light source (6).

Title: Angular crank drive, for pump or engine
Inventor: STRAHM ANTON
IPC: F02B75/02
Filed: 1993-03-08
Abstract: The invention relates to an angular crank drive, which converts reciprocating movement into rotational movement. The angular crank drive has applications in two and four-stroke engines, pumps and timing mechanisms. The angular crank shaft (1) has an angularly arranged crank pin (2). On the connecting rod (4) the piston pins (5), corresponding to the number of pistons, are fitted to the pistons. At least four pistons may be arranged on one angular crank (4 pistons = 8 cylinders). In Fig. 1 there are 2 pistons = 4 cylinders. The simple translation of reciprocating movement into rotational movement has an effect on the following factors: weight, power, manufacture, overall size and environmental impact. Mixture preparation also in two-stroke engines without oil additives. A two-stroke engine with 2 pistons and 4 cylinders has already been produced. In four-stroke engines the valves are timed by way of gears. <IMAGE>

Title: Genetic engineering method for demonstrating the recessive red factor in cattle
Inventor: KRIEGSMANN BERND
IPC: C12Q1/6876
Filed: 1993-10-29
Abstract: Problem: At present there is no method for identifying carriers of the red factor in cattle by the genotype although there is a need. Solution to the problem: Using the polymerase chain reaction (PCR) the bovine melanin-stimulating hormone receptor (bMSH-R) is demonstrated. Using the ligase chain reaction (LCR) or restriction enzymes in a routine test, the alleles of the gene which are responsible for the phenotypical expression of the hair colour in cattle are visualised. Uses: The main use is in increasing the efficiency of breeding programmes for red breeds of cattle. Farmers are able to increase their income by selling breeding stock which are in demand.

Title: Prepn. of substances for combination by application of reverse magnetic polarity - enhances subsequent physical or chemical processes
Inventor: SHISHENG LI
IPC: B01J19/08
Filed: 1993-10-29
Abstract: In a process to prepare two different kinds of material before they are joined to form a single compound, the novelty is that before they are combined the two substances are passed through a magnetic and/or an electrostatic field in a combiner. The field polarities around the two substances are opposite. Pref. magnets are arranged each side of each respective passage each of which has the same polarity as its neighbour. Adjacent passages bearing the different substances each have opposite polarity.
