Title: Temperature monitoring system for hot-glueing equipment and installations
Inventor: FELLER ERICH
IPC: G05D23/19
Filed: 1984-03-15
Abstract: In hot-glueing installations and equipment, the problem frequently arises that the adhesive or the commodity to be stuck is damaged by a faulty operation of the regulator which controls heating of the glue or faulty operation at another place in the closed-loop control. The invention therefore provides a monitoring system which ascertains the correct operation of the closed-loop control by monitoring the switching frequency of the regulator within certain periods of time and delivers an error signal if a certain minimum number of switching operations is not reached.

Title: Hall signal generator for producing trigger pulses for ignition operations in an internal combustion engine
Inventor: KAISER HARRY
IPC: F02P3/045
Filed: 1984-05-22
Abstract: A Hall signal generator for producing trigger pulses (26) for ignition operations in an internal combustion engine comprises a Hall element (19), a permanent magnet (18) and a masking rotor (17) which is made from soft iron and which has mask portions (23) which are separated from one another by gaps (22) and which are movable through a gap between the permanent magnet (18) and the Hall element (19). In accordance with the invention, the number of mask portions (23) is an integral multiple of the number of cylinders of the internal combustion engine, the pulses (25) produced thereby being reduced to the required number of trigger pulses by means of a frequency divider (24). Consequently, the flow of current in the primary winding (5) of the ignition coil (6) always extends over constant angular portions of the masking rotor (16). <IMAGE>

Title: Methods of manufacturing semiconductor circuit devices
Inventor: OGURO SETSUO
IPC: H01L27/082
Filed: 1985-01-31
Abstract: A method of manufacturing a semiconductor circuit device begins by providing two wells (3, 4) in a semiconductor substrate, each of these wells being of the opposite conductivity type to the substrate (2). The surface of the substrate is then oxidised and subsequently an I<2>KL circuit is formed in one (3) of the well regions. Finally, a MISFET circuit is formed in the second well region (4). This method allows the impurity concentrations in the two well regions to be controlled separately, thus giving improved electrical characteristics. <IMAGE>

Patent GB-2163595-A (GB)
Title: Improvements in fuel cell structures
Inventor: WARZAWSKI BERNARD
IPC: H01M8/24
Filed: 1985-07-25
Abstract: A single fuel cell (20) is built up from a plurality of plane members (21, 32, 42, 24). A plurality of such cells are stacked together to constitute a fuel cell structure. Each fuel cell in the structure requires access to three independent fluid circuits: an electrolyte circuit including an inlet orifice (88A, 98A) and an outlet orifice (88B, 98B); a gas fuel circuit including inlet and outlet orifices (108); and an oxidant circuit which may be constituted by inlets and outlets in communication with ambient air. In the final structure, these circuits must be effectively sealed from one another and from the surroundings (except for the special case of ambient air oxidant). This invention improves such sealing by preventing unwanted seepage between adjacent ones of the plane members (21, 32, 42, 24) due to defects in planeness and parallelism of the individual plane members. This is done by surrounding an area to be sealed off from another area by at least one rib which stands proud of the surface of the associated plane member and which is associated with at least one groove. When the stack is assembed the ribs are ideally deformed and received in the associated grooves, but in the vicinity of non-ideal portions of the plane members the ribs serve to block gaps through which the fluids would otherwise pass. <IMAGE>

Patent GB-2182451-A (GB)
Title: Nuclear magnetic resonance imaging
Inventor: YOUNG IAN ROBERT
IPC: G01R33/483
Filed: 1986-10-29
Abstract: In a nuclear magnetic resonance imaging method the production of magnetic resonance signals in a part of a body 45 being examined outside the region 53 of the body being imaged is prevented by placing magnetic material 49 adjacent that part of the body so as to distort in that part a magnetic field applied to the body during imaging. The magnetic material is suitably in the form of particles distributed in a flexible support member, for example a ferrofluid within plastics ducts in a soil textile fabric. By obtaining signals only from region 53 the resolution within that region may be increased without extending the imaging time or producing aliasing, e.g. using a two dimensional Fourier transform technique. <IMAGE>
