Filed: 1971-12-01
Abstract: 1367160 Windscreens SAINT-GOBAIN INDUSTRIES 1 Dec 1971 [8 Dec 1970] 55749/71 Heading B7J [Also in Division H4] In a vehicle window pane carrying aerial conductors, a closed screening loop is provided in the region of the edge of the panel. As described, a laminated windscreen 10, Fig. 2, has on its internal surface one or more aerial conductors 4, which may be deposited by a printing process and be baked on, and which are furnished with a terminal 5. A conducting strip 18, forming a closed loop, is similarly deposited on the periphery of the windscreen. A finger 19 extends upwardly from the centre of the lower part of the strip 18, and is furnished with a terminal 21. A rubber mounting ring 12, which may be of high dielectric loss material, supports the windscreen 10 within the vehicle bodywork 3, and conceals the strip 18 from view. A coaxial cable 6 extends from the aerial to a receiver 7, and the terminal 19 of the screening loop is connected to the sheath thereof. Alternatively, the screening loop may be connected to a point in the vehicle where parasitic voltages appear which have the same levels and frequencies as, but are opposite in phase to, the parasitic voltages existing in the vicinity of the windscreen mounting (Fig. 8, not shown). If a point cannot be found where the voltage equality and phase opposition conditions are satisfied, passive and/or active circuit components may be inserted in the lead from the screening loop (Fig. 9, not shown). In a second embodiment, the windscreen is a single sheet of toughened glass, but it is otherwise similar to the first embodiment (Fig. 5, not shown). In a third embodiment, aerial conductors 24, Fig. 3, are embedded in the interlayer 25 of a laminated windscreen, which is fixed to the vehicle bodywork 27 by adhesive 26, and a peripheral conductive loop 29 is also located within said interlayer. In a fourth embodiment a wire loop 36, Fig. 4, is located within the rubber mounting ring 34 of a toughened glass windscreen 31, near the periphery thereof. A fifth embodiment is similar to the fourth, but features a laminated windscreen (Fig. 1, not shown). In a sixth embodiment a wire loop is located within the adhesive fixing a toughened glass windscreen to the vehicle bodywork (Fig. 6, not shown).

Abstract: 1357189 Cupellation of lead noble metal alloys DEUTSCHE GOLD-UND SILBERSCHEIDEANSTALT 2 Dec 1971 [2 Dec 1970] 56002/71 Heading C7D A process for the cupellation of lead alloys containing noble metals includes effecting oxidation by introducing pure oxygen or oxygenenriched air into a closed converter. In an example, a crude furnace lead containing 16À04% Cu, 28À26% Pb, 34À21% Ag, together with e.g. Au, Zn, S, is subjected to cupellation employing oxygen or oxygen-enriched air; the resulting metal contains 7À04% Cu, 3À04% Pb, and 86À05% Ag, while the slag contains 22À12% Cu, 58À88% Pb and 1À20% Ag. Apparatus (see Figure)  The converter 1, lined with refractory material 2, is tiltable and rotatable; the hood thereof includes a filling opening and a heating unit. The crude material is introduced, the converter tilted and the charge melted. Oxygen or oxygenenriched air is blown in through lance 3 or through openings in the base of the converter (not shown), and no further heating is required since the process is self-sustaining. The oxygen input and pressure can be altered and the relative position of the lance can be varied. Slag is tapped from tap hole 4 continously during operation.

Abstract: 1,163,958. Purification of acetonitrile. BADGER CO. Inc. 14 Dec., 1966 [21 Dec., 1965], No. 56045/66. Heading C2C. Crude acetonitrile contaminated with water and other cyanic components is purified by passing the crude acetonitrile to an intermediate point of a distillation column together with a purification recycle stream containing a volatile aliphatic or aromatic hydrocarbon in which acetonitrile is soluble and which forms an azeotrope with water, as water entraining and separating agent, in a quantity sufficient to entrain water in the stream by distillation within said column, operating said column under conditions to vaporize said entraining agent and entrain water and other impurities volatile therewith and produce a relatively dry liquid acetonitrile concentrate with heavier nitrile impurities in the lower portion of said column, maintaining conditions at the top of said column to allow normal gaseous components to pass overhead while condensing the entraining agent, water, other vaporizable impurities and acetonitrile vapour within the column, continuously withdrawing a side stream containing acetonitrile, entraining agent, water and other impurities trapped within said column, cooling said side stream in the presence of said entraining and separating agent, separating a water phase and impurities soluble therein from the purified organic solution of said entraining agent and acetonitrile, and recycling said purified organic side stream solution to an intermediate portion of said column. The preferred entraining agent is benzene and the crude acetonitrile may be that obtained as a by-product in the production of acrylonitrile. The relatively dry acetonitrile bottoms solution may be passed to a second distillation column and distilled in the presence of nitrile stabilizers to separate volatile decomposed cyanic impurities from a relatively pure acetonitrile with-drawn as a side-stream, and from a heavier organic nitrile bottoms stream. An apparatus is described for the continuous purification of acetonitrile.
