Patent GB-2008299-A (GB)
Title: Remote control over power lines
IPC: H02J13/00
Filed: 1978-11-01
Abstract: In a remote control system wherein control pulses are sent over an AC power line, the transmitter has a triac 18 (or SCR) in series with a capacitor 20 across the line. The triac is triggered at selected peaks of the AC waveform to charge and provide the pulses. In a two-phase system a receiver on the out-of-phase line will receive weaker pulses than a receiver on the in-phase line. The detector at the receiver can be given such an AC bias as to compensate for this. Alternatively the triac is also triggered (to discharge the capacitor) at each zero crossing point following triggering at a peak, the detector in the receiver being synchronised to detect the control pulses at the zero- crossing points only. A plurality of triacs and capacitors could be used in turn. The pulses could be significant by their number or form a binary code. <IMAGE>

Title: Method and apparatus for sensing inplane deformation of a surface
IPC: G01B11/16
Filed: 1978-11-24
Abstract: A surface on which there is a regular periodic pattern, often a relief pattern (12), is deformed, and in-plane deformation is sensed by illuminating the deformed pattern with a beam (12) of coherent light so that light is reflected as one zero order beam and a plurality of diffracted beams, and combining two of the beams (16, 18) so that they interfere in a manner related to the deformation along the direction of intersection of the surface plane with the plane in which the two interfering beams lie. The magnitude and direction of in-plane deformation in one or more directions and the magnitude and direction of the maximum in-plane stress or strain, can be determined automatically.

Patent GB-2081966-A (GB)
Title: Image intensifier tubes
IPC: H01J31/50
Filed: 1979-03-05
Abstract: Battlefield image intensifier tubes are protected against damage caused by the relatively enormous heat and electron energy developed if the intensifier should by accident be pointed at a bright light source (such as a shell flash) by a slotted annular resistive element 20 placed around but touching the photo-emissive cathode layer 12 (preferably) to act as a high resistance between the cathode and the cathode-window mounting flange (and hence the H.T. power source). This causes both a temporary reduction in down-tube potential and a pinching- out effect of the electron flow from any point-like source on the photocathode when the tube is subjected to highlight overload conditions. <IMAGE>

Patent GB-2062973-A (GB)
Title: A robust, stable, and cheap commutation system for compact electric motors
IPC: H01R39/04
Filed: 1979-10-08
Abstract: A commutator has segments 6 supported by an insulating layer 5 on a flange 4 of a rotor disc 3, and the segments are contacted by brushes Br mounted on holders 9. Radial commutator segments (302, Figures 3, 4 not shown) may be mounted on discs (301) with the aid of insulating pads (303, 304), insulating rings (311, 316), or an annular member (314). Segments (504, Figure 5 not shown) of a radial commutator are secured to a disc (502) by lugs (505, 506). In Figure 6 (not shown), segments (605) are secured to a rotor (601) by means of a bed of insulation (603) and a flange (604) fixed to the rotor. In a brush holder 201, Figure 2, a spring 203 presses one end of a lever 205 via a sliding mass 204, and a force is applied to brush 207 by way of a further sliding mass 206. Previous applications have described the construction and advantages of "radial" type commutators. This application describes a construction which not only has the same sort of advantages for radial commutators, plus some improvements in the rigidity thereof, but is also applicable with some advantages to the construction of the more usual cylindrical commutators, albeit with use of the internal cylindrical surface rather than the external. The principles of construction are developed to the point where the commutator becomes an integral part of the rotor rather than a separate entity. An inertia-compensating brush holder without fluid, and so more suitable for use with the "internal" commutator, is also described. <IMAGE>

Patent GB-2058310-A (GB)
Title: Burning solid fuel
IPC: F23K3/08
Filed: 1980-08-08
Abstract: Solid fuel such as coal is fed into an inlet shaft of the furnace through a rotary feeder constructed to prevent the admission of air. Primary air channels supply the major part of the air required for combustion of the fuel in a region in which the fuel bed is sufficiently thick to avoid disturbance and the formation of "holes" by this air. Further, narrower air channels supply sufficient, diffused and low velocity air to complete the combustion of the fuel without substantial entrainment of grit and ash. Air is prevented from flowing in contact with the fuel up stream of the primary channels and the metering edge.
