Patent GB-2186833-A (GB)
Title: Pultrusion method
Inventor: SHAW STEWART DAVID ERSKINE
IPC: B29C70/52
Filed: 1986-02-20
Abstract: The method comprises pultruding a resin impregnated bundle of fibres (10), for example optical fibres or copper wires, and then enclosing the pultruded bundle within a coating prior to heating (24) the coated bundle (22) to polymerise the resin. The coating is then stripped off leaving a smooth surface to the profile. The coating is preferably applied by continuously extruding thermoplastic material in a tube around the bundle, but may be applied as a wrapped and optionally heat shrunk plastics film. The bundle may be preheated (18) to a temperature below the resin polymerisation temperature, prior to extrusion of the tube from an extrusion head (20). <IMAGE>

Title: Tracking magnetic discs
Inventor: STEWART ALEXANDER
IPC: G11B5/596
Filed: 1987-01-17
Abstract: A fine position closed loop servo system for magnetic disk storage media having one or, as shown, a plurality of data storage disks 3-5 utilises a first servo burst signal on one disk surface (as shown the top surface of the top disk 3), the first servo burst data being spaced at radial positions one-half track displaced from each of the odd-numbered concentric track centerlines and a second servo burst signal on another disk surface (as shown the bottom surface of the bottom disks), the second servo burst signal being recorded at radial positions one-half track displaced from each of the even-numbered concentric track centerlines. Both the first and second servo burst data are read simultaneously utilizing the data transducers 6 associated with the surfaces of the respective data storage disks and the envelopes of each of the servo burst signals are simultaneously, separately detected at 16, 18. The envelope signals thus detected are compared at 20 in order to generate a position error signal which is applied to the common head actuating mechanism 8 of the disk drive in order to maintain track centerline alignment of a data transducer during operation of the magnetic disk storage means. The system may include an optical grating for coarse positioning. On power-up the system is calibrated to determine the relationship between the outputs of the coarse and fine positioning systems, and may be recalibrated during operation. <IMAGE>

Title: Overcurrent circuit breaker with time delay
Inventor: LAI CHIN-FAY
IPC: H02H7/085
Filed: 1988-02-11
Abstract: An overcurrent circuit breaker for an electric system eg. an induction motor M, has a timer TM which produces a first control signal a1 a predetermined time after the system is turned on, and a load detector CT in association with an overcurrent control device VR which produces a second control signal a2 when the load applied to the system exceeds a predetermined level. The first and second control signals jointly activate an amplifier AMP to produce a third control signal a3 which activates a microrelay MR1 and a power relay PR to cause a magnetic switch MG to open, or trip, whereby the system is turned off. The time delay allows a current surge in the system to occur without causing the magnetic switch to trip during a starting period. The system may also be tripped by a thermal detector TH acting through a second microrelay MR2. <IMAGE>

Title: A munition containing confined explosive charge
Inventor: COUTURIER GUY
IPC: F42B39/20
Filed: 1988-10-11
Abstract: A munition (1) containing a confined explosive (12), is protected against a significant temperature increase such as that which would result from a fire. The envelope (10) of the munition (1) is provided with a zone (2, 3, 6) rendered so fragile that, during a temperature increase, the pressure buildup due to the decomposition of the explosive (12) produces an opening in the envelope (10), thus achieving a mechanical deconfinement of the explosive (12). In addition, the explosive (12) is chosen so that the kinetics of the decomposition-detonation be sufficiently slow for the mechanism of deconfinement to be effective before the explosion. In particular, an explosive of the composite type with a flexible binder is suitable. The fragile zone may be a solder join (2) between two parts of the envelope, fusible nut/bolt attachments, or fusible threaded inserts for attaching cheek (11) to envelope (10). Also, the cheek (11) may be attached by a crimp which is calibrated to fail at a safe internal pressure. <IMAGE>

Title: Map reading aid
Inventor: BAILEY ALFRED JOHN
IPC: G01C21/00
Filed: 1989-02-21
Abstract: A map reading aid for use in walking or other outdoor pursuits having a scale calibrated in a personal mobility parameter, such as travel time based on a predetermined walking speed, to enable the user to read off the value of the parameter between any two points on a map of a specified scale. Typically the aid will include a set of scales, each corresponding to a different walking speed, so that the walker can use the scale most closely corresponding to his estimated walking speed to measure his travel time between any two points on the map. Thus a succession of simple measurements will allow the walker to estimate his travel time over a route across variable terrain. In another form of the invention the personal mobility parameter is the numbers of strides based on a predetermined number of strides per unit of length. A walker can then use such an aid to assist him to determine distance travelled over the ground from a known starting point towards some other geographic feature which he wishes to walk towards. <IMAGE>
