Abstract: 1,188,007. Rear view mirrors. A. WILSON. 27 May, 1968 [22 July, 1967], No. 33833/67. Heading B7J. [Also in Division G1] A self-dipping mirror arrangement comprises a frame 4 carrying the mirror 1 pivotally mounted on a spring 6, a photo-cell 10 mounted in a holder 11, a solenoid 3. The photo-cell 10, which is shielded from stray light by the housing 11, on illumination by the headlights of a following car, is lowered in resistance causing solenoid 3 to be energized and to attract a ferrous pad 2 mounted on the wedge-shaped plastics backing 1A of the mirror 1, so that the mirror is pivoted into a position such that the reflected light due to the head-lights does not dazzle the driver. The mirror is pulled against the pressure of a U-spring 7, a plastics coated push wire (8) being provided to prevent chafing between spring 7 and the backing 1A. The frame 4 is manually adjustable about pivot 14. Rubber padding 15A is provided round the inside of the frame.

Abstract: 1,191,335. Resonant circuits; band filters. FERNSEHGER€TEWERK STASSFURT VEB. 25 July, 1967, No. 34036/67. Headings H1R and H1W. A tunable band filter, e.g. for a UHF tuner, is formed by a pair of resonant circuits 3, 4, formed by the removal of parts of one of the metal foils 1 coating the dielectric sheet 2, each circuit being provided with an inwardlyprojecting conductive portion 5, and with an end slat 6 which houses a variable capacity diode (not shown) for tuning the filter, the resonant circuits being coupled both by the intervening portion 7 of the metal foil, and by an additional conductor 8. Choice of position of conductor 8 permits manufacturing irregularities to be compensated for, the bandwidth being corrected by choice of the distance from the base line 9, and lack of symmetry between the circuits being corrected by suitably slanting conductor 8 with respect to line 9. Predominantly capacitive or predominantly inductive coupling is provided by arranging the circuits end to end with their slatted ends adjacent or apart, respectively (Figs. 2 and 3, not shown), to give a band width which alters over the range of tuning. To provide an approximately constant bandwidth over the tuning range, the asymmetrical arrangement of Figure 4 may be used.

Title: Improvements in or relating to welding electrodes
IPC: B23K35/368
Filed: 1962-09-06
Abstract: Tungsten carbide filler material in granular form for use in tubular electrodes is made by sintering a powder comprising one or more of tungsten carbide, tungsten and carbon and containing 4.3-4.8% carbon. Tungsten carbide powder is formed into granules, e.g. by rolling with a lubricant, pressing, centrifugation or by utilizing surface tension action, and sintered by heating to 1600-1700  DEG C.  Alternatively the powder may be a mixture of tungsten with tungsten carbide or carbon, e.g. soot. 0.2-0.3% of metal from the 8th group of the Periodic System, e.g. cobalt, may be added.  In a particular example 6450 gm. tungsten carbide, 2100 gm. tungsten and 20 gm. cobalt in powder form are mixed together and rolled with 5% paraffin wax to form granules. The granules are sintered by heating in a graphite tray at 1650  DEG C. for 45 minutes in an inert gas, e.g. hydrogen or nitrogen, or in vacuum.

Abstract: 1286404 Self cleaning valves L'OREAL 14 July 1970 [12 Aug 1969] 34152/70 Addition to 1226712 Heading F1R A valve for discharging a plurality of substances stored under pressure according to the parent specification 1226712 is modified to be self cleaning and comprises a discharge pipe 45, Fig. 1, with an aperture 16 normally closed by a portion 36a of a sealing washer 36, which discharge pipe 45 is movable within a cavity 43 of a slidable element 40 normally sealing apertures 5, 6, the pipe 45 passes through a grooved bore 41 and its closed end 45b engages a cup member 46 which has ridges 47a, Fig.5, normally abutting the undersurface of the slidable element 40. The pipe 45 has a shoulder 15 which does not contact the washer 36 and together with the grooves in bore 41 and those between ridges 47a allows pressurising fluid to enter cavity 43 and the space defined by portion 36a. Initial depression of the pipe 45 opens the aperture 16 so permitting escape of fluid thus cleaning the pipe's bore 45a. Further depression of the pipe 45 causes the shoulder 15 to close the bore 41 so preventing flow of pressurizing fluid, and eventually causes the slidable element 40 to open apertures 5, 6 to permit discharge of the substances contained in receptacles 21, 22. Should the fluid pressure increase the portion 36a distorts to allow escape of fluid.
