Title: Improved method for the manufacture of rare earth transition metal alloy magnets
Inventor: ROZENDAAL EWOUD
IPC: H01F1/06
Filed: 1987-02-27
Abstract: In a known method of manufacturing a sintered rare earth transition metal and boron magnet body, e.g. of Nd-Fe-B, the cast alloy is comminuted by hydrogen decrepitation in an atmosphere of pure hydrogen before further comminution, pressing in a magnetic alignment field, sintering and magnetisation. The use of pure hydrogen introduces a serious risk of explosion.

Title: Removing animal pelts
Inventor: ROBINSON ROY NOEL TUCKER
IPC: A22B5/16
Filed: 1987-11-17
Abstract: A pelt remover for removing the pelt from an animal carcase suspended by its forelegs has a gripping means (20) which grips a part of the pelt adjacent the neck or shoulders of the animal carcase and progressively peels the pelt from the animal carcase, then the gripping means (20) moves clear of the animal. The translational movement of the gripping means (20) is reversed so that the pelt is released and will drop free of the animal carcase before the gripping means (20) is moved to a position where the means are ready to remove the pelt from a next animal carcase. The pelt remover comprises a frame (7) and a pivotal arm (15) carrying the gripping means (20). The pivotal arm (15) is slideable in relation to a guide (11) in the frame (7). Arm actuating means (12) are provided to cause the arm to be translationally moved in relation to the frame in a direction which causes stripping of a pelt from an animal carcase which is held adjacent to the arm actuating means (12). <IMAGE>

Patent GB-2254415-A (GB)
Title: An optical sensor
Inventor: CUSH ROSEMARY
IPC: G01N21/55
Filed: 1991-03-22
Abstract: This invention relates to an optical sensor for testing a biochemical sample. The sensor includes a resonant mirror device 1 and a prism 2 disposed adjacent the device 1 for coupling an input beam of light to the device 1. The input beam of light having a comb spectrum with a uniform spacing between adjacent lines or bands of the spectrum is produced by a comb spectrum source 10. The comb spectrum may be produced by a diode laser with multiple longitudinal modes. The input beam of light is polarized by a polarizer 4 to provide equal TE and TM components. The resonant mirror device is arranged in the paths of said input beam of light such that resonance is excited for at least one of said components. An analyser 11 is arranged to receive said components of the beam of light reflected from the device 1 for producing an output beam having a spectrum including a series of bright and/or dark lines or bands corresponding to the lines or bands of the comb spectrum of the input beam. When a sensing layer of the resonant mirror device is sensitized by the chemical sample, an angular shift in the resonance angle takes place and this causes the lines or bands of the output spectrum to be swept across a reference point where detector means 12 is located to count the number of lines or bands swept across the reference point. The angular shift in the resonance angle is equal to the product of the distance between adjacent lines of the comb spectrum the number of lines swept across the reference point. <IMAGE>

Title: A pressure-limiting valve
Inventor: MUHR ULRICH
IPC: B60T17/18
Filed: 1991-04-19
Abstract: A safety valve (30), which is disposed in a hollow piston (22) of a pressure-limiting valve (10), has a valve closure member (31), which cooperates with a bore (32) in the base (27) of the hollow piston (22). The valve closure member is accommodated in a guide member (33), which forms discharge passages (43). The guide member (33) is provided with baffle surfaces (44), which restrict the cross section of the discharge passages (43) and are formed by webs. When the safety valve (30) becomes effective, pressure medium strikes the baffle surfaces (44) and generates a force which aids the lifting of the valve closure member (31) from the base (27) of the hollow piston (22). This enables the opening cross section of the safety valve (30) to be enlarged. The pressure-limiting valve can be used in compressed-air braking systems of motor vehicles. <IMAGE>
