Patent GB-2187267-A (GB)
Title: Estimating gun propellant charge temperature
Inventor: HODGES PETER
IPC: F42B35/00
Filed: 1985-12-24
Abstract: An estimate of the core temperature of a propellant charge used in a large calibre (eg. tank) gun, which core temperature is a prime factor determining explosive efficiency of the charge and actual projectile range and lags behind changes in ambient temperature, is obtained by providing a container 21 such as an ammunition case containing an explosively inert material 22, such as sand, packed to have a thermal conductivity and mass corresponding to the propellant material normally held therein. One or more electrical temperature sensors 24, 241 are disposed in the inert material in the vicinity of the core, and possibly at other depths from the surface, to give an estimate of the instantaneous temperature at the core and/or a temperature profile through the material which corresponds to the propellant of an ammunition round subject to the same ambient temperature conditions. The temperature at a predefined burn zone of such a propellant charge is determined by sensor signal processing means and applied to a fire control computer or the sensed temperature signals are applied to the computer which effects the estimate. <IMAGE>

Title: Reinforced articles of sanitaryware
Inventor: WOOD RICHARD
IPC: B29C70/68
Filed: 1986-01-21
Abstract: A method of forming an article of sanitaryware from a shaped thermoplastic shell and a curable backing composition, preferably of foamed polyurethane, wherein a metal structure is included in the curable backing to provide a heat sink for heat generated in the curing process, and optionally rigidising reinforcement for the article, the curing process being carried out in a closed mould. The process avoids the distortion of the thermoplastic shell which occurs when using curable compositions having exothermic curing reactions, particularly when the thermoplastic shell has been formed from sheet having a thickness of less than 5 mm.

Title: Evaporator mechanical defrost system
Inventor: HUBBARD PETER A
IPC: F25D21/06
Filed: 1986-02-18
Abstract: The present invention relates to a method of and apparatus for defrosting a freezing or cooling apparatus. The invention is embodied in the concept of brushing with a brush 5 the finned evaporator tubes periodically to remove accumulated snow and frost from the surface of the tubes and fins 2.

Title: High frequency windows for waveguides etc.
Inventor: LEWIS GARY
IPC: H01Q13/24
Filed: 1986-02-28
Abstract: A device having a high frequency window, which window comprises a rod 2 of low-loss high-purity ceramic passing through a closure wall 3 to extend on one or both sides thereof. The portions of the rod, which is preferably circular in cross-section, extending on either side of the wall are tapered preferably conically and may form mirror images of each other. Each conically tapered portion extends for a distance of at least a wavelength at the operating frequency of the device. Where the device comprises a rectangular waveguide 4 the diameter of the rod at the wall is equal to the height (or lesser cross-sectional dimension) of the waveguide. <IMAGE>
Patent GB-2172584-A (GB)
Title: Tamper-resistant outlet fitting
Inventor: GOTCH HENRY
IPC: B65D39/08
Filed: 1986-03-21
Abstract: A tamper resistant fitting for a container comprises a plastics insert (10) which is located coaxially around a part (9) forming a closure in the outlet (21) in the sidewall (20) of the container. The insert has a top flanged portion (15) which in use lies beneath the top plate (1) of the closure and is provided with three spaced lugs (13) so that the insert together with the top plate can be screwed into the outlet (21). When the closure is fully tightened, the lugs (13) are broken off, this then leaving only frictional engagement between the outer peripheral surface of the closure (9) and the inner peripheral surface of the insert (10). The frictional coefficient between the two surfaces is arranged so that rotation will not occur with normal forces occurring in use, but the parts will rotate at an applied value of rotational force which is less than that necessary to unscrew the insert (10) from the housing (21). A thin plastics cap (25) incorporates fingers (29) which deform during engagement with the housing (21) so that they lie beneath a protuberance (24). When the closure is removed the fingers are deformed downwardly and break off from the cap thereby providing evidence of tampering. <IMAGE>

Title: Ignition system for firing blasting caps
Inventor: DESROCHERS LOUIS-GEORGE
IPC: F42D1/05
Filed: 1987-04-14
Abstract: The system includes a transformer 15 having a primary winding 17 and a secondary winding 21 which is electromagnetically coupled to the blasting caps via small toroid transformers (49), (Figure 5). On connection to an AC source, A.D.C. power supply 1 charges a capacitor 3 to a predetermined voltage whereupon a sensing circuit 7 operates a latch 9 which turns off the supply 1 and activates a delay circuit 13. After a 30 m.sec delay a 10 KHz oscillator and flip flop circuit 35 is enabled to trigger driver circuits 27,29 alternately thereby producing an A.C. pulse train of decreasing amplitude by periodic discharge of capacitor 3 into the transformer primary 17. Each driver circuit has eight parallel-connected FETs (43), (Figure 2), and the transformer secondary delivers sufficient energy (eg. 950 volts peak, 6 amps average) simultaneously to fire up to 300 blasting caps (55) and allows the conventional inductance-cancelling capacitance in the secondary circuit to be omitted. <IMAGE>

Patent GB-2210463-A (GB)
Title: Electrode assembly
Inventor: GUNN THOMAS
IPC: G01F23/26
Filed: 1988-09-27
Abstract: A capacitance probe (10) for immersion in a liquid e.g. liquid metal (20) for the purpose of monitoring changes in the liquid level comprises a tube or sheath (12) of temperature- resistant dielectric material, such as a non-porous ceramic tube, enclosing a conductor e.g. in the form of a particulate conductive material (15), such as iron filings, packed into the tube or sheath (12) so as to be free to expand and contract axially and/or radially relative to the sheath. The plates of the capacitance are constituted by the particulate conductor and the liquid metal and the capacitance may form part of an oscillator whose frequency varies with the extent to which the probe is immersed in the liquid metal whereby the oscillator frequency provides a measure of the liquid level. The use of a conductor in the form of a packed particulate filling avoids problems with differential thermal expansion between the dielectric tube and the conductor. Other forms of conductor can be used eg a liquid or a tubular metal liner which can radially expand or is longitudinally split. The internal wall of tube (12) may be metallised. <IMAGE>

Patent GB-2240685-A (GB)
Title: Video signal processor
Inventor: KOJIMA MASANORI
IPC: H04N9/78
Filed: 1990-11-05
Abstract: A video signal processor used for a television set or the like for processing a video signal input for every horizontal line period. A video signal is processed by the operation such as comparison and addition of a video signal, a first delay signal which is delayed by one horizontal line period and a second delay signal which is delayed by two horizontal line periods. Since there is a horizontal correlation in a video signal, it is possible to separate a color signal from a luminance signal and remove the noise component from the luminance signal by a predetermined operation. The comparison is substantially the subtraction of the signals which are output one after another by a delay of one horizontal line period in series, thereby causing no trouble such as color edging. <IMAGE>
