Patent GB-2037415-A (GB)
Title: Spotlight
IPC: F21S8/00
Filed: 1978-12-15
Abstract: A fresnel lens (50) (not shown in Figure 1) and an objective lens (20) 2 are provided for selective mounting in a fixed location in a housing (11) to provide either fresnel or profile operation. A sub-housing (25) is slidably mounted in the housing for movement towards and away from the selected lens. The sub-housing mounts a lamp (41), a reflector (42), for directing light towards the selected lens, and a removable gate (26) having a central aperture 28 which is used for focussing purposes with the objective lens, but is removed when the fresnel lens is used. Filters may be mounted in a holder (22). The lampholder (40) is mounted on a carrier (43) slidable on the sub- housing (25) to adjust the position of the lamp relative to the reflector. <IMAGE>

Title: Improved thermally-conductive pipe
IPC: F28F21/08
Filed: 1979-02-08
Abstract: A pipe is described for embedding in floors, walls and ceilings and through which hot or cool fluids e.g. water, flows to heat or cool a room by conduction and radiation. The pipe (12) is formed from thermally conducting plastics material covered at least in part by a metal foil (14) having a high thermal conductivity to improve heat transfer. The foil may extend completely around the circumference of the pipe or only partially therearound and may be stuck to the pipe by means of an adhesive or may be e.g. high frequency welded thereto; adhesive may be coated or sprayed on the pipe before applying the foil. The foil is pressed or rolled onto the outer surface of the pipe and by applying sufficient pressure the foil can be impressed into the material forming the pipe wall so that the diameter of the pipe is not increased by the application of the foil. The foil typically consists of copper or aluminium or a copper- or aluminium-alloy. A method of applying the foil to the pipe involves laying the foil along the pipe as the latter leaves an extruder (16). Foil may be wrapped around the pipe in a helix with or without welding and/or an adhesive. <IMAGE>

Title: Improvements in Electroencephalograph Monitoring by Eliminating Unwanted E.C.G. Signals
IPC: A61B5/288
Filed: 1979-03-07
Abstract: The apparatus is particularly applicable to the fetus where EEG signals contain a component of those signals which give rise to electrocardiographs (ECG). In the apparatus ECG signals picked up by electrodes A1, B1 and C1 in an electrode assembly forming part of the apparatus may be eliminated by using a two gang potential divider which provides two signals having equal ECG components, the two signals being subtracted from one another to provide a signal representing EEG. An automatic circuit for removing E.C.G. signals (Fig. 7a not shown) is also disclosed. The electrodes may be concentric annular electrodes (Figs. 1 & 2 not shown), for example, or relatively small disc electrodes A1, B1 and C1 spaced apart at the vertices of an equilateral triangle (Figs. 3 & 4, 8a & 8b not shown).   <IMAGE>

Title: Seats
IPC: A47C4/02
Filed: 1979-04-10
Abstract: A knockdown seat, such as an upholstered armchair or settee, has a box-like base frame (1) and two arm frames (2) which are initially loosely connected to the sides (8) of the base frame (1), e.g. by bolts (7) located at one level preferably midway up the base frame (1). Once mounted on the base frame (1), the arm frames (2) have rearward portions (9) which project rearwardly of the base frame (1) and which each have an inwardly projecting rail (11). A seat back frame (3) is lowered between the arm frame rearward portions (9). The bolts (7) are tightened subsequent to the lowering of the seat back so that the back frame is laterally trapped between the arm frames (2) and thus assisted by the support given by the rails (11) to the rear of the back frame (3) both above and below the level of the bolts (7), the seat construction is made rigid. Bolts (7) may be replaced by hooks, the back frame (3) having upwardly diverging sides to that it acts as a wedge when lowered and tightens the connections between the base and arm frames (1, 2). <IMAGE>

Title: Brake assembly
IPC: B62L1/00
Filed: 1980-03-28
Abstract: A brake assembly includes a main brake shoe 11 carrying a main brake pad 12 and an auxiliary cleaning means 22 is mounted on and upstream of the main pad 12 with respect to the intended direction of motion of the surface e.g. of a cycle wheel rim 15 to be braked. The cleaning means may comprise a squeegee blade, but is shown as a subsidiary pad 22 mounted on a shoe 21, mounted on shoe 11. A biassing leaf spring 24 is arranged so that on operation of the brake the pad 22 engages the rim 15 first to wipe water and dirt from the surface and further movement of a calliper brake arm 16 moves the pad 12 to engage the rim 15 to perform braking action on the cleaner and drier rim 15, the spring 24 allowing the pad 12 to advance relative to the pad 22. The pad 22 has ridges 23 inclined at an acute angle to the direction of motion of the rim 15. In the embodiment of Figure 2 (not shown) mounting of the subsidiary pad involves a rigid support (31) bolted to shoe 11 and guide pins (32) and coil springs (34, 35). <IMAGE>

Patent GB-2056200-A (GB)
Title: Device for accelerated heating of the washing liquid in a laundry washing machine with a rotary drum
IPC: D06F34/08
Filed: 1980-06-17
Abstract: A washing machine has a single heating element (6) connected in series with the rectifier bridge (2, 3, 4, 5) for the supply voltage of the motor (1) which drives the drum. During each half cycle of the mains voltage, the heating element (6) is first connected in series with the rectifier bridge (2, 3, 4, 5) and subsequently connected by a triac (9) directly to the mains. Since the motor (1) is thus driven at a low speed with a substantial torque at the beginning of each half period, a current will flow in the heating element (6) which is substantially equal to that obtained when it is connected directly to the mains. The invention is used for obtaining simultaneous "stirring" and "heating" functions of the washing machine. <IMAGE>
Patent GB-2079125-A (GB)
Title: Captive bolt pistol
IPC: A22B3/02
Filed: 1980-07-02
Abstract: A captive bolt pistol for the humane slaughter of animals is described in which the shank of the captive bolt is provided with an axially extending bore which extends from the forward end of the shank so as to provide communication, at least when the bolt is in its forward position, between the firing chamber of the piston and the exterior surface of that portion of the shank which projects beyond the muzzle of the pistol. The gases emanating from the exploding cartridge, which cause the bolt to move forward, to stun the animal, escape through this bore and this has the advantages of reducing the noise, more effectively stunning the animal and ejecting a portion of the skull from the shank. <IMAGE>

Title: Excess Charge Removal in Charge Transfer Devices
IPC: H01L29/10
Filed: 1980-07-25
Abstract: A semiconductor charge transfer device wherein the substrate impurity content varies in a direction perpendicular to the insulating layer 7 in such a manner as to provide under an electrode 9 biassed to store charge a potential barrier between part of the substrate 1 adjacent the insulating layer and the remainder of the substrate which is sufficiently low to allow excess charge to overflow from said part of the substrate into the remainder of the substrate rather than into a part of the substrate under an adjacent electrode not so biassed. In an embodiment the substrate comprise a P type layer 11 between N type layers 5 and 13. Layer 13 is connected to a fixed bias and as the phase electrode potential is varied the depth of the potential well formed in layer 5 and the height of the potential barrier in layer 13 also vary. The invention finds particular application in imaging devices to provide anti-blooming without reducing responsivity and resolution. <IMAGE>
