Title: Composite material
Inventor: COX JAMES HOWARD
IPC: B44C3/08
Filed: 1986-03-14
Abstract: A plastics material which may be perforated is rendered conducting on all exposed surfaces and a metallic layer is deposited by electrolysis to all the exposed surfaces producing an article in which the plastics material is totally encapsulated in metal. The plastics material may be a sheet which is shaped before being rendered conductive. Shaping may be done by vacuum forming and if the plastics material is perforated it is overlayed with a sheet of imperforate plastics material which is discarded after the vacuum forming step. The material may be styrene and the metal may be copper or nickel. The material will be particularly useful in the manufacture of decorative items such as ornaments and ladies hats.

Title: Production of synthetic plastics articles
Inventor: WELCH CLETUS NORMAN
IPC: B05D7/02
Filed: 1986-03-27
Abstract: A method for imparting a photochromic response to a synthetic plastics article comprises   (a) applying a substantially mottle-free, substantially homogeneous film of polymeric resin, having a photochromic material dissolved therein onto at least one principal surface of the plastics article, (b) heating the film-bearing plastics article at temperatures near to but below the melting temperature of the photochromic material for a time sufficient to incorporate a photochromic amount of the photochromic material into the subsurface of the plastics material, and (c) thereafter removing the photochromic-lean film from the surface of the plastics article.   Photochromic articles prepared by this method are useful in optical applications such as lenses, filters and automotive windshields.

Title: Educational game
Inventor: NGUYEN HOANG VAN
IPC: A63F3/04
Filed: 1986-03-26
Abstract: Educational game apparatus comprises a track shaped like the periphery of a geographical area, an aircraft model suspended from the track, and means for remotely controlling movement of the model round the track. Both the speed and height of the model can be controlled. The height is controlled through an electric motor situated in the model and acting to alter the length of the member suspending the model from the track. Sections of the length of the track correspond to respective parts of the geographical area (e.g. states of the U.S.). The game involves stopping the model on the track section corresponding to a nominated part (state), whereupon the latter is illuminated, whilst having the model at its lowest altitude to represent landing, this being indicated by a light on the model. <IMAGE>

Title: Fabric folding machine
Inventor: ATKINSON CYRIL MILLWARD
IPC: D06F89/00
Filed: 1986-08-07
Abstract: A folding machine comprises a support 2 with rollers 3 under which material from rolls 1 can be drawn. The support 2 reciprocates between first and second positions in the latter of which it overlies folding stations which each comprises pivotal blades 5,6,7. A guillotine 9 is disposed adjacent the folding stations. Material can be drawn from the rolls by reciprocation of the support 2 after the free ends of the material are clamped to an edge 12 of the folding station by a clamp 11. Guillotine operates to sever lengths of material on the folding station from the remainder. Clamp 11 is released and blades 7 pivot anticlockwise to produce the first fold and then blades 5 and 7 pivot respectively clockwise and anticlockwise to produce further folds on the materials positioned on platforms 8. The platforms 8 are pivoted anticlockwise to pack the folded material piece into packets 14. Operation of the support 2, blades 5,6,7, guillotine 9 and clamp 11 could be automated. <IMAGE>

Patent GB-2208749-A (GB)
Title: Gas cooled nuclear reactors
Inventor: WILKIE DAVID
IPC: G21C3/322
Filed: 1985-11-22
Abstract: The graphite sleeves of a fuel stringer (10) of a gas cooled nuclear reactor are formed with a rib/groove profile (32, 33) on their external surfaces in order to increase the resistance of flow through an annular passage between the stringer (10) and the seal bore (18) of a channel (16) during raising or lowering of the fuel stringer from or into the reactor core. The ribbing has an asymmetric profile so that the resistance to coolant flow is less when the stringer is in situ in the reactor core than when the stringer is being raised or lowered. <IMAGE>

Title: Reluctance motor drive circuit
Inventor: POLLOCK CHARLES
IPC: H02P25/08
Filed: 1988-07-25
Abstract: A multiphase converter for a reluctance motor has a dc supply (+V, O) and an array of switching elements (S41-S44) to supply unipolar pulses of current to the phase windings (21-24). Each switching element connects one end of at least one phase winding to one of the supply rails and each freewheel diode (D41-D44) provides a path for freewheeling motor current when the associated switching element is turned off. Each switch is rated at the voltage seen by the motor. Less than two switches are required per phase. Diodes (D21-24) in series with certain phases block unwanted current paths. A novel switching algorithm allows currents flowing in any phase windings which share the same switch to be simultaneously controlled. Motors with an odd number of phases cause no power imbalance in the dc supply. Such motors offer a multiple stepping mode and can be wound to reduce the motor hysteresis loss. <IMAGE>

Filed: 1988-12-12
Abstract: An apparatus for transporting items having projecting edge portions includes at least one flexible belt, in the form of a closed loop round pulleys and having at least one longitudinal slit 7, 8 in the front face. When two belts are used they run side by side in the same direction with their front faces facing each other along a straight section, at the start and finish of which each belt passes over a pulley having such a shape that it causes the longitudinal slit 7, 8 to open to receive or relinquish an edge portion of an item carried between the belts. Instead of a slit a discontinuous break or more than one such slit or break may be provided. The slit or breaks may be held closed along the straight section by e.g. channel members 14 engaging the back faces of the belts. Alternatively the belts may include an internal resilient structure for this purpose. <IMAGE>

Title: Adaptive antenna
Inventor: HUDSON J E
IPC: H01Q3/26
Filed: 1990-09-17
Abstract: In an adaptive antenna, weighted auxiliary channel signals are combined with a main channel signal to eliminate jamming signals from particular directions. Where relative movement takes place between the antenna and jamming sources (e.g. a scanning antenna), the weights are calculated from an extrapolated covariance matrix which is smoothed by a least squares algorithm. The sampled data to provide the matrix may be subjected to a time window to avoid blurring of the steered nulls due to the relative movement. <IMAGE>

Patent GB-2242060-A (GB)
Title: Tritium removal
Inventor: WARING STEPHEN
IPC: G21F9/00
Filed: 1991-03-01
Abstract: Where a concrete structure (12) has been contaminated with tritium (whether as gas or as water) the tritium atoms take the place of ordinary hydrogen atoms in water and in hydroxyl groups in the concrete, rendering it radioactive. The degree of contamination may be reduced by irradiating the surface with microwaves to vaporize water, while extracting water vapour from the surface region through a dust filter (28) and a water trap (30). This can considerably reduce the radioactivity, and hence the cost of disposal of the concrete. <IMAGE>

Title: Burner control
Inventor: NAKAI GARY TOSHIO
IPC: F02N19/10
Filed: 1991-06-15
Abstract: in order to control the heat output of a burner whilst optimising its efficiency, the temperature of air near the burner or of combustion gases is monitored. If the temperature decreases, the fuel supply is increased by an increment. If the temperature increases, the air supply is increased if this is possible; otherwise the fuel supply is reduced by had an increment. Application is to heating the coolant of a diesel engine to warm the engine and battery prior to cold starting. The control may also test operation of the coolant pump, glow plug, fuel pump and air blower, may check that a flame exists, and may switch off the burner once the coolant temperature reaches a desired temperature (175 DEG F). <IMAGE>
