Title: Process and apparatus for effecting solid-state reactions
IPC: B01J8/00
Filed: 1961-11-02
Abstract: A process for effecting solid-state chemical reactions for the production of non-oxidic refractory materials, e.g. borides and carbides, from extrudable mixtures comprises extruding a mixture containing finely-divided thermally reactive refractory-forming materials into a shape, drying said shape to render it selfsupporting, heating said shape in a freestanding position to effect reaction and recovering the products.

Title: Improvements relating to vehicle headlight-controlling arrangements
IPC: B60Q1/14
Filed: 1965-09-15
Abstract: 1,116,527. Control systems for vehicle lighting. DAIMLER-BENZ A.G. 15 Sept., 1965 [15 Sept., 1964], No. 39409/65. Heading H2H. A manually-operated system for controlling the illumination of the headlights of a motor vehicle comprises means whereby an open circuit occur in the leads to the headlight flashing switch causes the headlights to be automatically switched to dipped beam operation. Closure of an ignition switch 37 causes partial energization of relay coil 16 by way of a resistor 41 across the contacts of a headlight flasher switch 42. This energization is sufficient to open contact 15 but not to close contact 17. To flash the headlights switch 42 is closed briefly causing full energization of relay coil 16 whereupon contact 17 closes. Closure of this contact causes energization of relay coil 10 which changes over contact 9 and closes contact 11, closure of which latter contact energizes the main beam headlamps 1. Opening of switch 42 again places the resistor 41 in series with the relay coil 16 so that contacts 15, 17 return to the open position thus deenergizing relay coil 10. Contact 11 then opens to extinguish the main beam headlamps 1 but no movement of contact 9 takes place. During dark conditions with the lighting switch operated so that contacts 27, 47 are made the dipped beam headlamps 2 are energized by way of conductor 46 and contacts 8, 9. Operation of switch 42 causes change-over of contact 9 to contact 7 so that the main beam headlamps 1 are energized. Further operation of the switch 42 causes the system to revert to dipped beam illumination by again changing- over contact 9 to revert to contact 8. Under main beam illumination an open circuit at a point X or failure of fuse 25 windings 16, 10 will be de-energized. A pulse of current will be supplied to winding 10 however by way of conductor 46, contacts 7, 9, lead 13<SP>1</SP>, contact 15 and lead 19. The contact 9 is thus changed over to contact 8 giving dipped beam illumination. The lighting switch 27 functions in the normal manner to illuminate the ancillary lamps on the vehicle and is combined with a switch 36 for fog lamps and the like. The switch 42 is combined with a switch 43 for use with the flashing direction indicating lamps.

Abstract: 1473836 Air cushion vehicles BRITISH HOVERCRAFT CORP Ltd 7 Aug 1974 [15 Aug 1973] 39592/73 Heading B7K An air cushion vehicle is stabilized in pitch and roll by the provision of high pressure cushions within the main cushion area one on each side of the vehicle longitudinal axis in the forward part of the main cushion with possibly a third one on the longitudinal axis in the rear part of the main cushion. Each stabilizing cushion structure comprises a first continuous loop of material 11 secured to vehicle structure 12 at 11a and terminating in a lower edge 11b and a second continuous inner loop 15 attached to structure at 15a and terminating in a lower edge 15b. The two loops 11 and 15 are respectively symmetrical about offset inclined axes 14 and 16 thereby forming a curtain air duct 22 which is wider at the rear than at the front and which connects with a duct 21 in the body 12 supplied with air by a centrifugal fan 19. Alternatively an axial flow fan may be used. To prevent water scooping by loop 15 it is formed with an inwardly and upwardly directed lip 17 with a reinforcing bead 18 between the loop and the lip. The air flow 23 generates a high pressure cushion 29 and feeds air also to the main cushion 24. As shown in Fig. 4 each high pressure cushion may be enclosed by the main skirt 25 or it may be incorporated within the skirt (Fig. 6, not shown).

Title: Methods of producing synthetic resin products
IPC: B29C33/06
Filed: 1963-10-10
Abstract: Synthetic resin products may be prepared by introducing into a mould a mixture of materials capable of reaction to form a synthetic resin and effecting the reaction of the materials by heat generated within the reactive mixture by the application of electromagnetic field energy having a frequency of 107 to 1013 cycles per second. The resins may be foamed in which case a foaming agent is added to the mixture, and the mould may be formed by the walls of an insulation space, e.g. a refrigerator cabinet. The preferred synthetic resins are polyurethanes which may be derived by the reaction of a diisocyanate with a polyester, polyether or polyesteramide. Other resins mentioned are those prepared from unsaturated polyesters, from vinyl materials such as vinyl chloride or vinylidene chloride and epoxy resins. Suitable blowing agents are fluorohydrocarbons and water for the polyurethanes while for the other polymers nitrogen releasing compounds or carbon dioxide may also be used.
