Title: Hulling soya beans
Inventor: BARTESCH HELMUT
IPC: A23N7/00
Filed: 1984-11-08
Abstract: The soya bean material (1), i.e. the bean seeds with hulls adhering thereto is fed via chute (6) to a beating tool (2). The struck material is thrown into a trajectory against a wall (4) for impact. The single beating and impact results in a substantial separation of the hull and the seed. The material thus produced is then carried along the wall (4) which has projections thereon, for any hull adhering to be rubbed off. The wall may contain holes (5) at the circumference of the circular path of the tool. The smallest inside diameter or lateral dimension of the holes is preferably 1.3 to 1.8 times greater than the largest particle size of the material. Alternatively, the wall may be solid and semi-circular with internal projections. <IMAGE>

Title: Position location system
Inventor: SIDDALL ROBERT JAMES
IPC: G01S5/16
Filed: 1984-12-07
Abstract: In a position location system for enabling an object 3 equipped with a receiver and microprocessor to locate its position, two base stations 1, 2, situated a known distance apart, transmit laser beams rotating about vertical axes. One station 1 transmits two contra- rotating laser beams (A, B) and the other station 2 transmits at least one laser beam C; all the beams rotate at the same angular velocity and are capable of individual identification by each being transmitted on a unique (but parallel) plane of rotation. The receiver and microprocessor on the object 3 calculate the angular bearing and thus the position of the object from the differences between the times at which the signals from the different rotating laser beams are detected at the receiver. <IMAGE>

Title: Load-sensitivity controllable braking pressure control unit
Inventor: SCHOPPER BERND
IPC: B60T8/18
Filed: 1986-02-21
Abstract: The control unit has a transmission lever (8) acting upon actuating tappets (2, 3) of pressure limiting or reducing control valves through a bolt (11) and a tilting element (10); a first spring arrangement (30) is articulated at a vehicle part which changes its position relative to the braking pressure control unit in a load-sensitive manner and is articulated at transmission lever (8) via a length-adjustable correcting arrangement (33). Between the transmission lever (8) and the actuating tappets (2, 3), a second spring arrangement (31) is provided, which urges the transmission lever (8) against a stop (32) formed fast with the housing. The abutment surfaces of element (10) and bolt (11) then have a distance (x) therebetween. This ensures that in setting of the first spring arrangement (30) by arrangement (33) incorrect length adjustments are compensated within limits without impairing the change-over pressure.

Title: Hot-deformed powder metallurgy articles
Inventor: ASLUND CHRISTER
IPC: B22F3/14
Filed: 1986-08-27
Abstract: Process for the production of powder-metallurgy articles, a powder of a metal and/or metal alloys being filled into a thin-walled cartridge or capsule or the like, whereafter the same is sealed and hot-isostatically pressed to produce a blank which is then hot-shaped, more particularly by forging or rolling, into the end product, is characterised in that to obviate cracking in the hot-shaped end product, the powder-filled capsule or cartridge is pre-pressed with an increase in temperature and pressure to predetermined values without the predetermined temperature and pressure values being maintained, and then hot-shaped into the end product. To this end, the blank was heated during hot deformation to an even higher temperature e.g. above 1200 DEG C. Hot-isostatic compression is so performed that the blank has a density of approximately 90 to 98%, more particularly approximately 95 to 98%, of the theoretical density. In an Example a blank was heated to 1100 DEG C while the pressure was increased to 700 bar. Without dwell- i.e.without long remaining at this temperature and pressure the blank was then heated in a conventional oven to a temperature of approximately 1200 DEG C, and then rolled in this state in a pilgrim state rolling mill into a tube.
