Abstract: 1486979 Coating aluminium-containing surfaces NATIONAL AERONAUTICS & SPACE ADMINISTRATION ]2 March 1975 [12 March 1974] 10365/75 Heading B2E [Also in Division B3] A method of treating an aluminium-containing surface to prepare it for joining with a similarly prepared surface comprises chemically treating the surface to remove any aluminium oxide therefrom, coating with a solution containing a sealer of polystyrene, the polystyrene having the property of preventing significant permeation of oxygen to the surface and being thermally removable from the surface leaving essentially no residue and allowing the solvent of said solution to evaporate leaving a coating of the polystyrene on the aluminium oxide free surface. The polystyrene may be applied as a solution containing 0.5 to 5% of polymer and the solvent may be acetone or toluene. The aluminium oxide may be removed by reaction with an alkali metal oxide at elevated temperature.

Title: A method of producing steel from pig-iron
IPC: C21C5/28
Filed: 1956-04-06
Abstract: A method of producing steel from pig iron in a bottom blown converter comprises blowing an oxidizing gas through the bottom during the whole of the conversion and injecting an oxygen containing gas on to the surface of the bath from the beginning of the blow at least until a liquid slag is formed.  The bottom and top blasts may be air, oxygen-enriched air, or a mixture of oxygen and water vapour.  The area of the bottom tuyeres may be reduced by 50 per cent, keeping the blast pressure at that normally employed.  The surface blowing may be carried out for the first eight minutes and the charge finished by bottom blowing.

Title: Method of producing sugar-coated dicalcium phosphate
IPC: A23G3/00
Filed: 1961-03-23
Abstract: A preparation for tableting and for incorporation in chewing gum and foods such as bread and bakery goods as a dental caries preventative is made by mixing dicalcium phosphate in fine particle form with an equal weight of sugar in the form of an aqueous solution containing about 15% of water and continuously agitating the slurry so obtained to allow heat of the mixture and heat of crystallization of the sugar to evaporate water present and produce dry, free-flowing, discrete, sugar-coated dicalcium phosphate particles.

Abstract: 1,026,811. Retractive switches. ILLINOIS TOOL WORKS Inc. March 19, 1963 [March 19, 1962], No. 10932/63. Heading H2B. An arm 52 carrying moving contact 54 is held in pivotal engagement with an actuating lever 48 by a spring 50, which also serves to hold the lever 48 in pivotal engagement with terminal member 12. The arrangement is such that when the lever 48 is moved to the position indicated by broken lines the spring 50 moves overcentre to snap the contact 54 into engagement with fixed contact 26, but at all times the spring urges the lever 48 towards its rest position (shown in full lines) where it abuts a resilient insulating buffer 46, preferably of nylon. The lever 48 may be operated manually or otherwise. In a modification (Fig. 3, not shown), the insulating buffer 46 is carried on the lever 48 and a change-over arrangement of fixed contacts is provided. The lever 48 may be of plastic material and the insulating buffer omitted; in this case the spring 50 conducts current to contact 54 and is made of beryllium copper.

Title: Toy vehicle with sonic responsive steering systems
IPC: A63H17/39
Filed: 1975-03-18
Abstract: 1475462 Toy vehicles TOMY KOGYO CO INC 18 March 1975 [4 April 1974] 11211/ 75 Heading A6S [Also in Divisions G4F and G5J] A battery powered toy vehicle has stearable front wheels operated by a control system activated by a sonic transducer in response to an external sound source. The vehicle comprises a chassis 10, rear wheels 36 driven by motor 18 powered by batteries 14, and front wheels 66 attached to a stearing mechanism. The steering mechanism comprises a support 46 and a bracket 52 mounted above chassis 10 but interconnected by two connector brackets 58, Fig. 6a, such that relative movement between support 46 and bracket 52 causes front wheels 66 mounted on axles 64 to turn relative to the chassis 10 to steer the vehicle. By means of abutment 67, Fig. 6, on support 46 and abutment 68 on chassis (10) the front wheels may only assume a straight-ahead or right turn configuration. The relative movement between support 46 and bracket 52 is accomplished by rotation of a generally oblong member 84 attached to a shaft 78 journalled at its rearward end in chassis 10 and at its frontward end in bracket 52 and having a gear wheel 80 mounted approximately at its midpoint. A leaf spring 88 attached to bracket 52 urges against four prongs 86, Fig 6b, attached to member 84 and arranged to preferentially hold member 84 in a vertical or horizontal position. In a vertical position the front wheels 66 assume a straight ahead configuration, however, when member 84 rotates in direction of arrow in Fig. 6 it bears against abutment 90 on support 46 to cause the front wheels to assume a right-hand turn configuration against force of spring 72 attached to support 46 and chassis 10. Rotation of member 84 is accomplished by the selective interengagement of gear wheel 96 attached to a shaft 92, having a crown gear 94 rotated by motor 18 via rear axle gearing arrangement (Fig. 8, not shown), with the gear wheel 80 on shaft 78. Gear wheel 96 is normally held in spaced relationship with gear wheel 80 by spring 100 attached to the chassis (10). When the toy vehicle is in motion the car may be steered by squeezing a trigger (118) (Fig. 5, not shown) of a hand-held device (106) remote from the toy vehicle to bend a resilient metal plate (110) to cause a "clicking" sound which is picked up by a gonic transducer (124) (Fig. 4, not shown) mounted on the toy vehicle, e.g. on the roof thereof, and converted by an electronic circuit (Fig. 9, not shown) to an electric current which energises an electromagnet 102, Fig. 6, to attract the shaft 92 engaging gear wheels 96 and 80 and rotating member 84.
