Title: Anti-intruder security system
Inventor: HAMPSON DOUGLAS JAMES
IPC: G08B13/00
Filed: 1988-09-01
Abstract: The system is deployed to protect a building 10 from undesired intrusion and has a plurality of mobile units 22 which, before activation, are each located in respective housings or "kennels" 18. Upon activation of, for example, one mobile unit. it moves out of its respective kennel and follows a substantially arcuate path 20, the radius of which is dictated by a tether 30 to which the mobile unit is connected. The areas protected by adjacent units overlap to form a complete interdiction region 16 which surrounds the exterior of the building. Each mobile unit also includes a detection means comprising, for example, an-infra-red sensor, the infra-red beam of which extends from a housing. The approaching mobile unit may respond to the approaching intruder in a variety of ways (e.g. audible, visual, tactile) so as to deter further advance of the intruder and also render the intruder readily identifiable. <IMAGE>

Patent GB-2211513-A (GB)
Title: Production of fuel briquettes
Inventor: STEAD WILLIAM JOHN
IPC: C10L5/04
Filed: 1988-10-28
Abstract: A method of producing fuel briquettes from a powdered fuel and a binder comprises the step of subjecting the powdered fuel to a treatment (e.g. pressure and/or heating) effective to promote adhesion between the fuel particles and the binder. In a preferred embodiment for producing fuel briquettes from powdered anthracite and a binder such as molasses, the powdered anthracite is dried to a lower-than-usual moisture content below 5% by treatment in a fluidised bed drier operated to raise the temperature of the anthracite to a higher-than-usual temperature about 100 DEG C. The higher temperature treatment promotes improved adhesion between the fuel particles and the binder and so improves "Green strength" of the fuel briquettes. A detergent may be added to the powdered fuel or binder a mixture thereof.
Patent GB-2226276-A (GB)
Title: Self-inking hand stamp
Inventor: TSE WILSON MEE SHUEN
IPC: B41K1/50
Filed: 1988-12-22
Abstract: A hand stamp has a handle 14 from which is suspended a pre-inked stamp 18, the handle being resiliently urged in an upward sense. The handle 14 is connected by a screw threading 56, 58 to a shaft 30 supporting the stamping member, enabling adjustment to vary the extent of depression of the handle before it contacts a stop surface 44. Thus the compression of ink pad 18a can be adjusted in order to compensate for drying of the pad etc. Relative rotation of handle 14 to shaft 30 is normally prevented by engagement of projection 74 on handle upper body 50 in recesses 76 on an intermediate member 60 which is itself non-rotatable with respect to housing it. <IMAGE>

Patent GB-2233454-A (GB)
Title: Locating the source of a seismic disturbance
Inventor: JACKSON PETER JAMES
IPC: G01V1/20
Filed: 1989-05-19
Abstract: A method of locating the source of a seismic disturbance includes the steps of positioning at least three geophones into a mineral seam via a borehole, detecting with the geophones two distinct wave forms, eg compressional and shear waves, obtaining electrical signals representative of the wave form and combining the information from the wave forms to indicate the actual or apparent position of the source. The three geophones are directed along mutually perpendicular axes to detect direction of the source and the range is inferred using the different wave velocities for the wave forms received. The method may be used to detect the collapse of burnt seams in the remote gasification of coal.

Patent GB-898411-A (GB)
IPC: H01S1/02
Abstract: 898,411. Masers. SIEMENS & HALSKE A.G. April 28, 1959 [April 30, 1958], No. 14471/59. Class 40 (9). [Also in Group XXXVI] A semi-conductor maser amplifying arrangement comprises a semi-conductor body having a transition zone between N- and P-type zones which is forward biased so that, in response to the application of electromagnetic waves of a certain frequency to the transistion region, greater energy is released in the form of electromagnetic waves of the same frequency. Fig. 2a shows a PN semi-conductor body 1 with two overdoped zones forming non-rectifying contacts to which annular electrodes 4 and 5 are applied. Radiation having a frequency less than the ratio of the energy gap of the material to Planck's constant impinges on the body 1 releasing amplified radiation in the transition region when excited electrons fall into traps or into the valence band and recombine with holes. A microphone 9 modulates the current flowing through the semiconductor and thus the total energy of the emitted radiation. Fig. 3 shows a body comprising a PN junction mounted in a waveguide which conveys the impinging and the emitted radiation. Hollow dielectric members may be used in place of the conducting waveguide members to convey the radiation, or the semiconductor way be located in a cavity resonator. A magnetic field may be applied to the transition region to split the energy level of a trap into two or more slightly different levels to allow for an increase in the wavelength of the emitted radiation; frequency modulation may be effected by this means. The length of the transition region should be considerably greater than the wavelength of the emitted radiation. The semi-conductor material may consist of silicon, germanium, A 3 B 5  compounds or bismuth telluride. Impurities to provide traps may consist of nickel, copper iron or lattice imperfections.

Title: Roll over protection member for vehicle seat
Inventor: SCHMUTZ CHRISTIAN
IPC: B60N2/48
Filed: 1990-08-17
Abstract: A rollover protection member 3 that is associated with the back rest of a vehicle seat is movable by means of an adjustment device from its rest position into its operating position, in which it protrudes upwards over the upper end of the back rest, the adjustment device being designed as a fast-drive system with energy storage in the form of a pretensioned coil spring 31. A sensor recognises danger, eg inclination of the car or wheels off the road, and activates an element, eg an electromagnet 40, which moves a toggle interlock 36, 37, so releasing the coil spring from its tensioned position. The spring untensioning causes plunger pipe 7 to move outwardly from within pipe 4, the outward limit of pipe 7 being defined by spring loaded pins 12 falling into transverse holes in pipe 7. Further interlock pins 15 fitting into further openings 16 in pipe 7 allow for manually locking the pipes together in selectable positions. The member 3 has two pipe and spring arrangements on either side of the back rest, (Figure 2). <IMAGE>
