Abstract: 1457659 Photo-electric control of vehicle lighting MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 26 April 1974 [19 Oct 1973] 18466/74 Heading G1A Vehicle lights are automatically switched on when the level of natural ambient light falls below a given value, the effects of artificial lighting (e.g. street or vehicle lights) being eliminated by using a photo-detector sensitive only to the near ultraviolet band 3200-3600A. The detector may be at the front or rear of the vehicle, and may be set to receive ambient light from the same road area as can be illuminated by the lights it controls. The detector is preferably a stannic oxide photoconductor whose output is supplied to a threshold device; the latter may have several thresholds so that different lights come on for different ambient levels. A graph showing the response of the detector and the relative emissions of the sun and artificial sources is given, Fig. 2 (not shown), the above mentioned ultraviolet range being one in which the sun emits but the other sources do not, in this range the ultraviolet is related to the sun's visible emission.

Title: Improvements in cans and the like containers
IPC: B65D25/54
Filed: 1933-06-30
Abstract: 423,358. Glass manufacture. FARRER, J. O., 27, Chancery Lane, London.-(Continental Can Co., Inc. ; 100, East 42nd Street, New York, U.S.A.) June 30, 1933, No. 18596. [Class 56] [See also Groups XVII and XXII] A food-stuff can or like container is provided with a glass disc 8 secured by means of a continuous metal - to - glass hermetic joint within a metal annulus 4 adapted to be seamed to the body of the container. The disc, which is of heat-resisting glass, is provided with a metal rim 9, integral with the glass and extending around the peripheral edge portion and on to adjacent portions of the upper and lower surfaces of the disc, the rimmed disc being secured by soldering to a seating formed in the metal annulus. In producing the rim, a metallic deposit is first formed on the edge of the disc, for instance by applying thereto a paste composed of bronze powder, lead borate powder, and turpentine, which is fused in place at about 1000‹ F. Alternatively, the deposit may be produced by applying to the disc successive molten layers of glass containing metallic powder, the layers gradually increasing in metallic content, or again it may be produced by any electrolytic, fusion, or other suitable process. The metallized disc, however produced, is cleaned in an acid bath, and the rim 9 is formed over the metallic deposit by dipping it into a bath of molten hard-solder containing 90 per cent tin and 10 per cent zinc, the surface being covered with a flux consisting of equal parts of ethylamine hydrochloride and glycerine. The rimmed disc is attached to the annulus 4 by means of soft solder applied manually or otherwise to the parts, conveniently in an electric furnace of which the temperature is limited to 400‹ F., the accumulated solder bond 10 filling the space between the rim and the wall 6 of the annulus. For this operation, the disc is merely rested on the seating 7, no pressure being applied to the parts.

Title: Improved method of manufacturing core store matrix planes
Inventor: SELFE BARRY DAVID
IPC: G11C5/05
Filed: 1966-04-28
Abstract: 1,075,130. Magnetic storage apparatus. MULLARD Ltd. April 28, 1966, No. 18667/66. Heading H3B. A magnetic core matrix plane with a heat sink is manufactured by securing a plurality of cores to both sides of a heat-conducting laminar base member, supporting the base member in a frame, wiring the cores as required, and securing the wires to the frame. The cores are first arranged in the desired pattern in a vacuum jig and the baseplate, which consists of an aluminium sheet having protruding corner pieces bent over to form spacers and having indentations for the cores, is coated with dry adhesive and brought into contact with the cores. When the cores have adhered the vacuum is released and the baseplate, with the cores attached to it, is removed. The plate is then secured in a frame by means of supports which extend from the corners of the frame and are screwed to the protruding corners of the baseplate. The cores on both sides are wired with row, column and diagonal wires, all of which are secured in slots in the frame and connected to connection tags on the frame. The matrix is tested by inserting the frame in a test rig and if satisfactory the wires are cut between the baseplate and the frame and the screws holding the baseplate are removed. The assembly may be lacquered after wiring.

Abstract: 910,043. Aerials. COSSOR Ltd., A. C. March 30, 1961 [May 26, 1960], No. 18714/60. Class 40 (7). A reflector for radio waves comprises two perpendicular boards, each board formed of two electrically conducting sheets separated by a honeycomb structure formed of paper strips, the planes of the strips being substantially perpendicular to the planes of the sheets.

Title: Flare light compensator

IPC: G03F3/08
Filed: 1971-06-03
Abstract: 1327854 Television HAZELTINE CORP 3 June 1971 [3 Aug 1970] 18724/71 Heading H4F The effect of flare light on the image produced by a cathode-ray display tube, particularly the effect on small dark areas in high-key images, is compensated by means (connected in the video signal path to the tube) which has a D.C. to A.C. transmission ratio of less than unity. The invention is described in connection with a display system termed a "Graphic Arts Process Simulator" in which maximum brightness is produced by minimum video signal level so that maximum dark is produced by maximum video signal level (See Figs. 3A and 3B) and thus by restricting the D.C. component of the video signals (to about 95% of normal value) signals representative of high-key images (which have a low D.C. component) are established at a higher (darker) reference level than low-key image signals (which have a high D.C. component) so that, as shown in Fig. 4, the dark areas in the high-key images are produced even darker than indicated by the video signal thereby offsetting the brightening effect of the flare light. The compensating means may comprise as shown at 10 (Fig. 2) the parallel combination of an adjustable resistor 22 and a capacitor 23 which may be connected between an output amplifier 15 for one channel e.g. the Red (R) channel of an XYZ to RGB matrix and an input amplifier 16 of a non-linear amplifier forming part of a "Graphic Arts Process Simulator" (Fig. 1, not shown).

Abstract: 824,882. Dynamo-electric machine casings. BRITISH THOMSON-HOUSTON CO. Ltd. May 14, 1958 [June 17, 1957], No. 19022/57. Class 35. Stator laminations 1, e.g. of a fractional H.P. motor, are located in a shell 5 by one or more indentations 6 or 8 which are made in the shell after assembly, and which engage recesses formed in the periphery of the lamination stack. Preferably these recesses are formed by the indenting operation, the laminations having been weakened at the appropriate points, e.g. by apertures 3 whose edges 4 are inwardly deformed to form the recesses. The indentations do not extend the full length of the stator so that the neighbouring undeformed laminations provide axial location. Alternatively, the weakening apertures 3 may be provided in selected laminations only. The laminations are secured together by riveting or welding.

Filed: 1974-05-02
Abstract: 1448523 Change-speed control AUTOMOBILWERK EISENACH VEB 2 May 1974 [5 July 1973] 19215/74 Heading F2D A valve comprising a pair of resiliently loaded valve members 3, 4 is operable automatically to connect hydraulically operated elements of an automatic transmission of a vehicle with either an engine driven pump 1 or a pump 2 driven at a speed proportional to that of the vehicle road wheels. When the vehicle is stationary with the engine at rest the loading spring 31 of the member 3 positions the members 3, 4 as shown, with a land of the member 3 against an abutment 91, so that fluid may be delivered from the pump 2 through conduits 20, 51, 52, 5 to the hydraulically operated elements of the transmission during towing or push starting of the vehicle. The pump 2 also fills the hydraulic torque converter of the transmission. Generation of pressure by the engine driven pump 1 causes the member 3 to be displaced against its spring so that the pump 1 discharges through the conduits 52, 5 and the pump 2 is connected to reservoir through a conduit R 2 . Selection of a ratio above the lowest results in a pressure being applied in a conduit 8 to move the member 4 into contact with the abutment 91 so that the pump 1 discharges to reservoir through a conduit R 1 , and pressure acting on the left-hand end of the member 3 is relieved enabling that member to be moved leftwardly by its spring to reconnect the pump 2 to the conduit 5 through the conduit 51.
