Patent GB-706067-A (GB)
Abstract: 706,067. Electric condensers. COMPAGNIE GENERALE DE TELEGRAPHIC SANS FIL. Jan. 28, 1952 [Feb. 7, 1951], No. 2286/52. Class 37 Ceramic powder of dielectric constant exceeding 3,000 and of grain size less than one micron is mixed with a binder which wets the powder. The ceramic powder is preferably an alkaline earth (e.g. calcium) titano-zirconate, but stannates and ceriates may be used. It is ground in a ball mill so that the particles are roughly spherical and of diameter about 10<SP>-3</SP> mm. It is mixed with phenolic resin, silicones, vinyl acetate, glystal, polythene, tetrafluorethyl, tetra chlorethyl, or cellulose derivatives, or wax or glass, or enamels or varnish. The organic plastic binders may be dissolved in toluene to enable the mixture to be deposited by painting, spraying &c., the material being afterwards heated to evaporate the toluene and harden the binder. The powder may be mixed with oils to produce a liquid dielectric, continuous agitation being employed to prevent the powder settling. Flat plate condensers may be made by alternately depositing the dielectric with a conducting paste on a base plate, Fig. 2 (not shown). Cylinders 1, Fig. 3, may be coated with the dielectric by spraying at 2, an oven 5 providing for hardening. In Fig. 4, flexible metal'foils 20 are cleaned at 24, dried at 26, coated with the dielectric at 21 and wound together at 25 in an hardening oven. In Fig. 5, a flexible strip 30 e.g. nylon is coated with dielectric at 33, and a conducting paste at 34, the two being hardened at 31 and coated again as often as desired.

Title: Construction of heated floor and method of laying the floor
IPC: F24D3/14
Filed: 1978-07-03
Abstract: Flooring comprises mounting panels 12 having protrusions 14 projecting therefrom and which are laid on the bearing structure (e.g. joists or concrete) of the floor, flooring panels 18 overlying and being supported by the protrusions. Heating ducting 16 runs between the protrusions and adhesive 20 secures the panels 18 to the protrusions. The invention provides for additional adhesive to provide an elongate web of adhesive extending on both sides of the ducting between the panels 12,18. The adhesive, which can incorporate a thermally conductive filler, provides a heat path between the ducting 16 and the panels 18. In the method the adhesive is applied to the lower face of the flooring panels so that when these are placed in position on the protrusions the adhesive runs down the sides of the heating ducting until it sets to form the web. <IMAGE>

Title: Power generating system
IPC: F03G7/00
Filed: 1978-10-16
Abstract: In a power generating system, heat energy is supplied to a hot reservoir (601) from the Sun, from used power station cooling water or from any other source of low-grade heat including freshwater or seawater at temperatures down to freezing point, in which case the source of heat is the latent heat of fusion of the water. Heat energy is rejected from an energy-converter of the system to a cold reservoir at a temperature below that of the hot reservoir (601) and, by use of heat rejection means (611), radiated at night to the sky and outer space from the cold reservoir which may consist of ice and water held in high-altitude lakes at temperatures of 0 DEG C down to -60 DEG C. <IMAGE>

Title: Holographic imaging using electromagnetic waves
IPC: G01S13/89
Filed: 1978-11-09
Abstract: An array of antennae comprises linear transmitter antennae 10 interleaved with receiver antennae 11. The array is focussed to produce a narrow vertical beam. An object to be imaged, e.g. a gun hidden under clothing of a person, moves horizontally past the array as the person moves. The beam is scanned vertically by selectively connecting the transmitter antennae in a preset order to a coherent source of microwaves comprising a stalo 6 and coho 7 and by connecting the receiver antenna in a preset order via a mixer 12 receiving the output of the stalo 6 to a phase sensitive detector 13 which also receives the output of the coho 13, and which detector feeds signals I and Q representing phase difference between the phase of the coho and the phase of waves reflected from the object to a signal processor. The signal processor includes a beam former which computes from the signals I and Q the components I', Q' (which would have been produced by a large number of beams of high resolution in the vertical direction) of the phase differences due to reflections from respective resolution cells in the vertical strip. The processor operates on the signals to ensure that there is a desired contrast in phase. <IMAGE>

Title: A polarity-reversal modulator
IPC: H04L27/20
Filed: 1979-03-27
Abstract: A polarity-reversal modulator, for use in, for example, channel converters in carrier frequency systems, has four transistors (Tr1 ... Tr4) of which the transister (Tr1, Tr2) of a first pair, and likewise the transistors (Tr3, Tr4) of a second pair, have their emitters connected to one another: two transistors belonging to different pairs (Tr1, Tr4; Tr2, Tr3) have their bases connected to one another. The carrier frequency (UTR) is supplied in push-pull fashion to the bases of the four transistors. In modulators of this type it is desirable to achieve a reduction in the space requirement by integration, by having as few as possible external terminals and ensuring that the capacitances at these terminals are as far as possible ineffective. The modulation input signal (U) is fed into one of two common emitter lines, each having a respective constant current source (J1, J2) and the output signal is taken from the common collectors of the two transistors (Tr1, Tr3) connected to the output (Tr5) of a current mirror (Tr5, Tr6). <IMAGE>

Title: Improvements relating to drive systems for gaming machines
IPC: G07F17/34
Filed: 1979-08-24
Abstract: A 'fruit machine' has reels which are driven by stepper or DC motors. Instead of a separate motor driving the reel, the reel itself forms the rotor.

The stator can be co-axial with or at the rim of the reel. In the DC motor version, coils (13) can be printed or otherwise provided at intervals around the reel and be commutatively energised to have reversing polarity. These co-operate with a permanent magnet (15). The arrangement can be reversed with magnets (17) on the reel and a fixed coil (18). <IMAGE>

Title: R.F.-protected explosive device
Inventor: OLOHAN NORMAN JOHN
IPC: F42C19/12
Filed: 1979-08-28
Abstract: An electrically initiated explosive device comprises a tubular metal body 1 and a central contact 2 coaxial with the body and insulated from the body by dielectric material 34, thus forming transmission path. A bridgewire 5 brIdges the contacts internally of the device and an electrical current is applied to it via external contacts C1 and C2 to initiate an explosion. When handled in the presence of R.F., the transmission path transmits the RF to the wire 5 making the device hazardous. In order to reduce the hazard, a resistive layer 9 is placed across the input X-Y of the path to dissipate RF at the input. A resistance 9 may be placed anywhere across the path.
