Title: Electrical machine
IPC: H02P29/02
Filed: 2003-07-12
Abstract: In order to be acceptable for safety critical applications, it is necessary for an electrical machine to allow continued operation despite an electrical short circuit in one of the operational phases of that electrical machine. It will be appreciated that an electrical short circuit creates excessive electrical current through the short circuit with significant heating and other detrimental effects. However, the electrical machine can operate with one operational phase disabled. In such circumstances, the present invention incorporates means for determining an electrical short circuit has occurred and then injects an electrical current approximately equal to or greater than the rated electrical current. In such circumstances, the operational phase or coil 4, 24, 34 is effectively protected despite the electrical short circuit and hence the electrical machine can continue to operate.

Title: Coin discriminating apparatus
IPC: G01V3/10
Filed: 1983-02-09
Abstract: Various electrical coin testing arrangements are described which may be used in coin sorters or in coin validators for example.

Patent GB-8414133-D0 (GB)
Title: Interlock mechanisms
IPC: F16K35/06
Filed: 1984-06-02
Abstract: An interlock mechanism for three rotatable members 26, 27 and 28 mounted in a body 18 with their axes parallel and having a chordal flat 33, 34 and 35 respectively includes a ring 48 which surrounds with clearance those parts of the members having the flats. When one member is turned from its base position to engage its cylindrical surface with the ring, the ring is slid laterally to engage with the flats of the other two members, which thereafter cannot be turned until the first member is reset to its base position. The interlock mechanism is particularly suitable for use with fluid flow control valves, where one of the members may be arranged to connect the drive to a valve operating component when turned from its base position. Two keys may be provided, one for effecting turning movement of each of the two other members, the keys being releasable only when the associated rotatable member has been turned from its base position. By restraining movement of the two keyed rotatable members other than when the valve is set to one or the other extreme setting, respectively, the valve may be operated only when both keys are present, and possession of a key guarantees the valve is set to an extreme setting.

Patent GB-8620071-D0 (GB)
Title: Structures of polymeric plastics material
IPC: B29C71/04
Filed: 1986-08-18
Abstract: Large fittings or other structures are made by rotationally moulding a first component 18 of polyethylene and joining cylindrical pups 20, 22, 24 of polyethylene to the component by butt fusion joints 26, 28, 30. The structure within the boundary 50 is irradiated with gamma radiation followed by post-heating to remove free radicals. The extremities of the pups are shielded to prevent irradiation. Their capability to be joined to polyethylene pipes 12, 14, 16 by butt-fusion joints 32, 34, 36 is unimpaired. The irradiation introduces cross-linking to give improved properties such as impact resistance and stress crack resistance and to bring the fitting within the specification for polyethylene pipe for natural gas distribution. The joints 26, 28, 30 are made using differential heating of the ends to be joined to compensate for differences in melt flow index. Alternatively, the component 18 is slightly irradiated to lower its MFI before pups are joined to it.
Patent GB-8801807-D0 (GB)
Title: Biological sensors
IPC: G01N21/55
Filed: 1988-01-27
Abstract: A biological sensor which utilises the phenomenon of surface plasmon resonance to detect the refractive index change which occurs when two components - for example antibody and corresponding antigen - react with one another. Surface plasmon resonance takes place at the sloping exit surface of an optical waveguide such as a fibre optic 23. The input end of fibre optic 12 is connected to a light source 12. A layer 25 of metal is applied to the sloping exit surface so as to cause total internal reflection of the light proceeding down the fibre optic. Reflected light is detected by a detector 13. A sensitive, for example antibody, layer 26 is applied to the metal layer. Sample (not shown) reacts with layer 26 in such a way that the refractive index changes. Provided conditions are correct, this variation in refractive index can be monitored in detector 13 by virtue of the surface plasmon resonance which occurs in the area of total internal reflection.
