Abstract: 1310807 Windscreens SAINT-GOBAIN 19 April 1971 [20 March 1970] 24876/71 Heading B7J [Also in Divisions H4 and H5] A transparent panel of composite safety glass, such as a vehicle window, is provided with at least one aerial conductor, which is arranged on one of the exposed surfaces of said panel. As described, two separate glass sheets 2, 3, Fig. 2, are bonded together by means of an intermediate layer 4 of, for example, polyvinylbutyral. Aerial conductors are applied to the exposed surface of the glass sheet 2, and normally face the interior of the vehicle. They comprise a central vertical conductor 6, and an upper horizontal conductor (5), Fig. 1 (not shown), forming a tee. The width of the conductor 6 may be less than 0À4 mm., so as not to obstruct vision, and both conductors may be made of silver. A paste is applied by the silkscreen process, and is fired during bending of the glass sheet, at a temperature of some 600‹ C. The vertical conductor 6 is spread out at its lower end to form a surface on which a contact pin 9 is attached by welding. A cable leading to a receiver within the vehicle is terminated by a clip, which is attachable to the pin 9. Resistance wires may be arranged within the intermediate layer 4, for electrically heating the panel. In an alternative arrangement, one of the outer sheets of a composite panel is made of plastics material, and the aerial conductor or conductors are arranged on the exposed surface thereof. The panel would be fitted in a vehicle so as to face towards its interior.

Abstract: 927,442. Electrophotographic reflex contact copying. E. N. MASON & SONS Ltd. Aug. 4, 1959 [Aug. 1, 1958], No. 24940/58. Class 98 (2). Contact copies are produced on flexible lighttransmitting sheets bearing a charged photoconductive surface layer by reflex exposure through the backing which is arranged nearest the light source and then, developing the charge image and, with or without transferring the so-formed image to a further sheet, fixing the powder image. Typically the copy sheet consists of a non-opaque paper backing coated with a dispersion of zinc oxide in a synthetic resin binder which may contain a sensitizing dye as in Specification 867,835. Preferably the original is a glossy white opaque paper bearing the material to be copied in black ink. Charging may be effected as described in Specification 864,370 or 867,834. By the use of a negatively charged copy sheet and a blackdyed resin toner containing carbon as in Specification 867,835 a laterally reversed positive image is produced by direct development and fixing while a correct-sided positive is produced if transfer of the powder image is effected before fixing e.g. as in Specification 892,611 or by moistening starch-filled tracing cloth and pressing it on to the powder image. Copies may be made from originals on tracing paper by backing the original with a mirror.

Filed: 1939-08-31
Abstract: 532,436. Welding. BUDD MANUFACTURING CO., E. G. Aug. 31, 1939. No. 24971. Convention date, Sept. 3, 1938. [Class 83 (iv)] In a method of resistance welding a number of sheets, one of the outside sheets having such a thickness in relation to the remainder as to preclude, due to the chilling effect of electrode, the formation of a welding nugget with satisfactory projection into the outer sheet, an additional strip . of similar heat conductivity is laid over the outside sheet and a current passed through all the sheets and strip sufficient to form a weld nugget penetrating into the outside sheet but not to the additional strip which is thereafter removed. In simultaneously spot welding together the skin sheets 10, 12 corrugated sheets 14, 16, 18, 20 and flanged stiffener 22 of an aeroplane wing, top and/or bottom additional thin layers 24, 26, preferably of the same material as sheets 10, 12, are placed between the outer sheets and the electrodes 30, 32 and a welding current passed through all the layers sufficient to fuse a nugget from all the layers except the additional layers 24, 26, which are thereafter removed. The sheets 10, 12, 24, 26 may be of stainless steel. The sheets 10, 12 may be of thickness less than 25 per cent. of the total thickness of the stack. Thus the stack may comprise sheets 10, 12 of 0.008 inch thickness, sheets 14, 16, 18, 20 each of 0.014 inch thickness, stiffening sheet 22 of 0.006 inch thickness and additional sheets 24, 26 of 0.004 inch thickness. With such a stack welding electrodes of 3/16 inch diameter a pressure of 350 lb. and a 60 cycle current of 4,000 amperes may be applied for a period of 5 cycles to produce a weld nugget which extends approximately 50 per cent. into the thickness of the layers 10 and 22.

Title: A process and an apparatus for expanding emulsions
IPC: C08F2/00
Filed: 1963-06-24
Abstract: 983,347. Expanding emulsions. FARBENFABRIKEN BAYER A.G. June 24, 1963 [June 30, 1962], No. 25051/63. Heading B1X. Emulsions under pressure in the presence of a gas in a pressure vessel 2 are discharged by the use of an air lock chamber 5 located below said vessel by (a) placing the chamber in communication with the gas phase in the vessel by means of a first valve 6, (b) placing the chamber in communication with the emulsion phase in the vessel by means of a second valve 7 whilst said first valve remains open, whereby emulsion flows by gravity into the chamber and completely fills it, (c) closing said first and second valves and opening a third valve 8 to discharge the emulsion, whereby the emulsion suddenly expands by a small, amount to release the pressure and thereafter is expelled from the chamber slowly without introducing excessive shearing forces, by release and expansion of small amounts of gas dissolved in the emulsion. The numerals refer to Fig. 1, in which the pressure vessel is a polymerization reactor, and which shows the automatic control system of a preferred apparatus. In another embodiment the pressure vessel is a separation chamber to which the reaction mixture is first passed from the reactor. A pressure sensitive device 11, Fig. 1, responds to the pressure difference between the upper and lower parts of the reactor and operates a regulator 14 which in turn operates a cam switch 15 controlling time relays 16-20 controlling the valves. Other features referred to include the location of the valve 6 above the level of the liquid in the reactor so that a quantity of gas remains above the emulsion when valve 6 is closed, and assists the expulsion when valve 8 is opened ; the provision of a further valve in communication with the air lock chamber whereby a gas for expelling the emulsion may be admitted from outside ; the use of several air lock chambers in series or parallel ; and various circuit arrangements.

Title: Improvements in or relating to variable-ratio hydrostatic drives
Inventor: TUNNELL FRANK GEOFFREY
IPC: B28C5/42
Filed: 1962-06-29
Abstract: 1,031,382. Hydrostatic transmission control. PLESSEY CO. Ltd. June 27, 1963 [June 29,  1962], No. 25144/62. Headings F2C and F2D. In a hydrostatic transmission for a vehiclemounted concrete mixer having a variable displacement pump 2 driven by the vehicle engine 1 and supplying pressure fluid to a fixed displacement motor 3 which drives a mixer drum 4, the output speed of the motor 3 is maintained constant (e.g. 5 r.p.m.) by adjusting the displacement of the pump 2 in response to variations of the pressure drop across a metering orifice 7 from a predetermined value. The pressure difference acts on a piston 10 connected by a linkage 11 to a pump central lever 12. An increased pressure difference moves the piston 10 right against the action of a spring 13 and reduces the displacement of the pump 2. The automatic control may be overridden by moving the lever 12 manually. During mixing the automatic control is overridden by manually opening a normally closed valve 15 which bypasses the metering orifice 7 and a small auxiliary metering orifice 7a, thus producing a higher speed of the drum 4. A pressure relief valve 5 is provided in parallel with the orifice 7. To facilitate ratio shift in the vehicle change speed gear the engine power taken by the drum 4 is reduced whilst the vehicle clutch is disengaged by closing a valve 19 in series with the orifice 7. A large pressure difference is thus created across the small orifice 27 and the displacement of the pump 2 reduced. A valve 21 connected to the clutch pedal linkage 18 supplies pressure fluid from a pump 22 to a fluid motor 24 which closes the valve 19 when the clutch pedal is depressed and the valve 21 vents the motor 24 through a restriction 29 to gradually open the valve 19 when the clutch pedal is released. During reverse operation fluid from the motor 3 is returned directly to the pump 2 through a one-way valve 6. The pressure relief valve 5 and one-way valve 6 may be formed as a single unit, Fig. 2 (not shown). The pistons 10, 24, valves 15, 19 and orifices 7, 7a may be formed as a composite unit in a single casing, Figs. 3-7 (not shown).
