Patent GB-2125970-A (GB)
Title: Proximity sensor
Inventor: KUERS GUNTER
IPC: G01P3/481
Filed: 1983-07-07
Abstract: A magnetic proximity sensor employs a sensor winding 5 arranged around a Wiegand wire 4 or like bistable magnetic element, and is of essentially rotationally symmetrical construction. The sensor has an axially magnetised tubular magnet 1 which enables the sensor to be incorporated into a device in any desired angular position in relation to the longitudinal axis 2 of the ring magnet 1. The internal field component due to the magnet 1 is opposed by a second field component generated by further magnetic means, so that the approach of a magnetisable object 7 in any radial direction causes a substantial change in the resultant internal field. The second field component may be provided by a magnet 3 radially magnetised as illustrated, or by a current injected into the sensor winding 5 itself. <IMAGE>

Title: Method of manufacturing coated resin bonded glass fibre rods
Inventor: CLUCAS RICHARD HALL
IPC: C08J7/046
Filed: 1983-09-28
Abstract: It is known to include a coupling agent (silane) in a filled cycloaliphatic amino hardened resin system which is employed in coating resin bonded glass fibre rods used as electrical insulators. It has been found that the method of introducing the coupling agent in the filled cycloaliphatic amine hardened resin system is critical to the success of the subsequent coating process. The invention lies in a method of preparing and treating a substrate of resin coated glassfibre material prior to coating with the filled cycloaliphatic amine hardened resin system which comprises the following steps:   a) the surface of the substrate is abraded or ground to remove the thin resin-rich surface layer which is formed during preparation of the material, thus exposing the composite structure of the rod and providing a roughened surface to promote mechanical adhesion, b) the exposed roughened surface is painted overall with the silane coupling agent.   The coating of the substrate with the filled resin system is preferably carried out in a mould whilst the substrate is in a state of stress e.g. under an applied tension, and the coating is preferably also cured whilst the stress is maintained in the substrate. Thus when the substrate is released from the mould the applied coating/interface is in a state of compression shear.
Patent GB-2135895-A (GB)
Title: Toy vehicle
Inventor: LEE JAMES S W
IPC: A63H29/06
Filed: 1983-12-09
Abstract: A toy vehicle has a gear box containing a clock spring which is wound by pushing the vehicle backward. A two part linkage connects the gear box to the frame. When the clock spring is wound, the resulting spring bias urges the linkage to one extreme position which locks the gear box in order to preserve the energy stored in the wound spring. When the linkage is pressed near its center, it moves to its opposite extreme position, which unlocks the gear box and releases the energy stored in the wound spring in order to propel the vehicle. When the vehicle is next moved backward, the linkage returns to the one extreme position which once again locks the gear box.

Title: Filter assembly for fluorescence spectroscopy
Inventor: KHALIL OMAR SOLIMAN
IPC: G01N21/64
Filed: 1984-05-18
Abstract: Apparatus for conducting fluorescent spectroscopy which involves irradiating a test sample with light of a first wavelength which causes the test sample to fluoresce light of a second wavelength and measuring a portion of the fluorescent light; irradiating the test sample with light of the first wavelength at reduced intensity and measuring the light of the first wavelength transmitted through the test sample; and comparing the intensity of the flurescent light to the transmitted light comprises an improved filter assembly which is rotatable between a test position and a reference position. The filter assembly includes a pair of test filters, one passing excitation light at one wavelength and the other passing fluorescent light from a test solution at a second wavelength, a pair of reference filters, each passing light at the first wavelength, and light shielding means to block stray light and prevent it from optically coupling between the filters. A pre-filter minimizes the background transmitted light. Insertion of the filter assembly into a commercially available automated clinical photometer enables the instrument to be used as a filter fluorimeter.

Patent GB-2198547-A (GB)
Title: Automatic weld visor
Inventor: JONES MARTIN PHILIP
IPC: A61F9/06
Filed: 1986-11-26
Abstract: An automatic weld visor is provided by a flexible welding filter (32) contained within a cassette (30) which is held in a housing (10) that may be fitted to any standard welding helmet or face mask. The filter is contained on a spool (34) that is biased by a spring (40) to position the filter in the operators line of sight. The filter may be further wound onto the spool to be clear of the operator's line of sight. This is achieved by a motor (20) that is contained in the housing and couples directly with the film spool. The motor holds the filter out of the operator's line of sight while energised and the filter returns under the action of the biasing spring when the motor is de-energised thus providing a fail safe operation in event of a circuit failure. To achieve this action an ironless rotor motor is used to overcome magnetic drag. <IMAGE>
