Title: Electric Heating Systems for Vehicles
IPC: B60H1/22
Filed: 1968-01-18
Abstract: 1,192,089. Electric heating systems for vehicles. FORD MOTOR CO. Ltd. 18 Jan., 1968 [30 Jan., 1967], No. 2765/68. Heading H2H. [Also in Division G3] The normal heating system of an automobile is augmented by an electric heating element 44 supplied through switches 46, 48, 50 from the alternator 32 whose field winding is controlled by a conventional vibrating-contact type voltage regulator 64 which in turn is controlled by a temperature sensitive switch 82 to provide unregulated operation of the alternator during the period immediately subsequent to starting of the vehicle, followed by regulated operation when a predetermined temperature has been reached. The heater 44 is only energized and switch 82 only operative when a control 28 is set to its maximum position in which switches 46, 48, 50 are closed and switches 104, 106 are open, movement from this position reversing the respective state of each of these switches. When starting and with the control 28 in its maximum position, the contacts 84, 86 of the temperature sensitive switch respectively open circuit the coil 95 of the voltage regulator 64 and the coil 97 of a relay 66 whose contact 78 connects the alternator output to the battery 60. Thus the contact 78 remains open to prevent the application to the battery 60 of the alternator unregulated output. When a predetermined temperature has been reached, the contacts 84, 86 close to energize the voltage regulator 64 and close contact 78, whose coil 97 is also supplied through the ignition switch 102. The contacts 84, 90 may be shunted by a thermistor. Fig. 3 (not shown) to provide a smooth transition from the unregulated to the regulated state of the alternator. In another modification, Fig. 4 (not shown), members 86, 96, 106 are omitted and the coil 97 is connected to the lead 92 through a diode. The automobile is provided with a heater chamber placed under the bonnet, communicating with the interior and containing the electric heater, temperature sensitive switch, thermistor (if provided), a fan 22 and the normal heater supplied from the engine cooling system, Fig. 1 (not shown). Various dispositions of these members in the chamber are discussed. Other refinements include a resistor in parallel with contact 78 to provide some battery charging when the latter is open and another switch in parallel with switch 108 to provide variable speed operation of the fan 22.

Title: Improvements in wetting, sudsing, emulsifying and detergent agents
Filed: 1938-01-31
Abstract: Crude secondary aliphatic alcohols having a hydroxyl value between 190 and 230 and boiling between 200 and 300 DEG  C. are mixed with primary aliphatic alcohols containing about 10 to 20 carbon atoms in the molecule before sulphonation by means of the products obtained by treating a metal chloride with sulphurtrioxide or a metal chloride or sulphate with chlorsulphonic acid.  Chlorides or sulphates of metals are used which give soluble salts with the products and residual hydrochloric acid which is liberated, or any bisulphate present is finally neutralized.  The crude secondary alcohols are those obtained (a) by oxidizing paraffins, saponifying the resulting mixture of products and extracting the alcohols present; (b) by fractionally distilling the products obtained by the catalytic hydrogenation of carbon monoxide and/or dioxide; or (c) by the catalytic hydrogenation of ketones. Suitable primary alcohols are those obtained by the catalytic reduction of tropical oils such as palmkernel oil and of tallow and similar fats.  Primary alcohols obtained by the sodium reduction of fatty acids from oils such as rape, fish, whale and linseed oils and unsaturated alcohols, mainly oleic alcohol obtained from sperm oil may also be used.  Triethanolamine may be used for the final neutralizing step.  The products have improved wetting, sudsing, emulsifying and detergent properties.

Abstract: 886,745. Removing slag. POWER, MINISTER OF. April 27, 1960 [Jan. 29, 1959], No. 3191/59. Classes 51 (1) and 51 (2). Slag from a gasifier is prevented from fouling the tapping hole 10 by the action of a high-frequency electric current passed through a coil 12 surrounding the hole 10. The floor 4 of the gasifier and the lower part of the walls may be cooled by water tubes 18, 21, and pulverulent fuel may be injected through pipes 30 extending through the tuyeres 5 into the slagging zone. The molten slag falls through a hole 24 in the upper surface of a conduit 23 to be quenched by a flow of water carrying away the quenched and fritted slag. An inner sleeve 28 with a hole 29 corresponding to the hole 24 can be moved away so that solid slag deposits may drop through the hole 24 and an opposing hole 26 in the conduit 23. The coil 12 may be formed of metal tubing cooled by water circulation.

Abstract: 561,823. Making turbines. AKT.-GES. BROWN, BOVERI, & CIE. Feb. 26, 1943, No. 3203. Convention date, May 28, 1942. [Classes 83 (ii) and 83 (iv)] Uniting by fusion.- In fixing the blades to the carriers of gas and steam turbines by circumferentially welding the blade roots, which are provided with guide slots or tongues, to the carriers which are provided with corresponding guide tongues or slots, an element of suitable material or size is provided, before welding, in the bottom of the slot so as to provide a space which enables the element to deform freely under the influence of the contraction strains caused by welding, to such an extent that the strains cannot exceed an allowable value. The blades are thus held tight on the carrier without causing very high strains which might result in internal cracks. The element may consist of a wire a of soft iron, copper or like inserted in the guide slot, preferably in a notch therein, or may consist of a projection d, Fig. 6, formed either on the blade or carrier. Either the blade as shown in Fig. 3, or the carrier may be slotted or the blade and carrier may be shaped as shown in Fig. 6. The weld b may be stress relieved by annealing, this being effected by welding thereover an additional layer f and subsequently removing this layer f by turning or milling.

Class 4 Boundary layer control means for fluid flowing relatively to a boundary wall is provided by the wall consisting of an inner and an outer perforated skin, 18 and 17, with a porous or granular filler 19 and means for drawing the fluid through all three layers. The stressed skin 11 of the aerofoil shown in Fig. 1 is formed with ridges 15 and 16 to correspond to ridges 20 in the boundary wall, and which may be fastened thereto by rivets, or by screwing down into spars 12. The spaces between skins 18 and 11, and consecutive ridges, form ducts through which the indrawn fluid may be guided. The ducts are joined to a manifold at the root of the wing, to which the suction means is also coupled. Control valves may be provided to restrict the flow through all or certain of the ducts. Deicing may be accomplished by passing an electric current through the filler 19 by electrodes 52 and 53 or electrode 51 and the perforated skins, which filler may be a conductor, e.g. carbon granules, or coated with a suitable conducting material. Provision may be made for similar boundary layer control of any part of the aircraft surface. The degree of perforation of the inner and outer skins, and the porosity of the filler may be varied from place to place. The filler may be confined by metal gauze or the like, to leave an air gap between it and the inner or outer skin.
