Abstract: 830,115. Automatic voltage control systems. INTERNATIONAL MARINE RADIO CO. Ltd. June 20, 1958 [June 25, 1957], No. 19827/58. Class 38 (4). A negative direct voltage at a terminal A derived through a voltage doubler SR1, SR2 from an A.C. output of an oscillator, comprising valves V1, V2 fed from an unregulated D.C. supply, is maintained constant by controlling the voltage feedback from an anode of valve V1 to a control grid of valve V2 by an amplitude limiter responsive to the direct voltage. The amplitude limiter comprises a diode SR3 bypassing to earth negative grid signal voltages and a diode SR4 limiting positive grid signal voltage to a valve dependent on the voltage between a point B and earth. Reduction in the voltage at terminal A raises the voltage at point B to increase the grid drive to the valve. V1 through the valve V2 and so tends to maintain the direct voltage constant. The direct voltage is adjusted by a potentiometer R6.

Title: Improvements in and relating to gaseous jet supported vehicles
Inventor: TUCKNOTT ROBERT GEORGE
IPC: B60V1/00
Filed: 1962-05-23
Abstract: 1,032,391. Vehicles capable of travelling on land, water and in the air. BRITISH AIR CRAFT CORPORATION (OPERATING) Ltd. May 15, 1963 [May 23, 1962], No. 19925/62. Addition to 1,026,810. Headings B7K and B7W. A ground effect vehicle temporarily supported by gaseous jet thrust has means installed which produce a vertical thrust of a magnitude less than the weight of the vehicle but exceeding the thrust required for steady hovering which enables the vehicle to leap above the steady hover height, also propulsion means which impart a forward speed to the vehicle, which is thus capable of leaping over obstacles of a given length and height, a ground effect cushion being formed by a plurality of ducted fans arranged along the side walls and along the front and rear walls of the vehicle, producing an outer and an inner jet curtain of rectangular plan form. As shown in Figs. 1 and 5, a ground effect cushion is formed by means of ducted fans 20 along the side walls and ducted fans 120 along the front and rear walls of the vehicle. Two internal combustion engines 3 are geared to a main gear-box 4 and thence by flexibly jointed shafts 5 and auxiliary gearboxes 6 to the fans 20, and by shafts 15 and auxiliary gear-boxes 16 to the fans 120. The inner jet curtain may have an inward flow component (Fig. 5). The vehicle wheels 2 are articulated to the vehicle body 1 by means of leading links 7 and trailing links 9 and are sprung by means of dual-purpose hydraulic jacks 10 serving also for retracting the wheels 2 up into the body 1 for hovering or leaping. One or other of the two engines 3 is used to drive the wheels 2, while for hovering both engines are used. The extra energy for a leap is stored preparatory to the leap in two contra-rotating fly-wheels 17 coupled to the main gear-box 4, from which the energy is derived during the leap. Preparatory to a leap, the engines 3 are set to maximum power and accelerate the ducted fans 20 and 120, which are in the fully feathered position, and the flywheels 17 to full speed and then, by setting the ducted fans to active pitch, the increased energy required for the leap is released both from the engines 3 and the flywheels 17. Stabilization in the air is effected by controlling the blade angle and/or rotational speed of the ducted fans differentially for both roll and pitch and steering may be effected by vanes in the jet outlets or by auxiliary jets. Flow straighteners may be provided below each fan and there may be a flexible skirt retractable by cables for ground running.

Abstract: 386,670. Electric signalling systems. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitõts- Ges. ; 2, Friedrich Karl-Ufer, Berlin.) July 13, 1931, No. 20093. Convention date, July 11, 1930. [Class 40 (i).] In an arrangement, suitable for use in lighting circuit diagrams, for indicating the positions of movable members such as, for example, switches, a reversing arrangement is provided in one position of which existing positions of the movable members are indicated by continuous light and changes of position by flickering light, and in the other position of which existing positions are indicated by no light and changes in position by continuous light. In the arrangement shown, which represents an indicating device for showing the position of a distant switch, A is a relay which is energized when the switch is switched to the " off " position, and E a relay energized when the switch is switched on. Each relay has a holding winding de-energized by the operation of a clearing switch Q. The condition of distant switches is indicated by lamps in pairs of which two lamps La, Le only are shown corresponding, respectively, to the " off " and " on " positions of a switch. The lamps are connected in series with a reversible switch K adapted to be connected, as shown, to an interrupter U and a hand-operated switch S. With the switch S in the position shown, lamp Le gives a continuous light. Assuming that the distant switch is opened, relay A is energized to close contacts a<1>, a3, open contact a<2>, and reverse switch K, whereby a circuit is complete through interrupter U and lamp La, causing the latter to flicker, until the clearing switch Q is operated, whereupon lamp La gives a continuous light. If the distant switch is now switched on, relay E is energized with consequent effect upon contacts el, e<2>, e3, and switch K, causing lamp Le to flicker, the light being steady when switch Q is operated. With the switch S reversed, assuming the distant switch to be switched on, relay A is energized, whereby a circuit through contact s<2> and lamp La is complete, causing La to give a continuous light. This light is extinguished when switch Q is operated. Assuming now that the distant switch is switched on, relay E is energized to light lamp Le which also is extinguished when switch Q is operated.

Abstract: 980,444. Separation of acrylonitrile and acetonitrile from aqueous mixtures by distillation. OSTERREICHISCHE STICKSTOFFWERKE A.G. May 25, 1962 [May 27, 1961], No. 20157/62. Heading B1B. Acrylonitrile and acetonitrile are separated from the aqueous reaction products of an acrylonitrile synthesis, wherein the acetonitrile content is 2-20% by weight based on the acrylonitrile, by a three-stage fractional distillation process. The feed mixture is passed through line 1 into column 2, where it is submitted to extractive distillation with 150-400 times the quantity of water (based on the weight of acetonitrile), introduced through line 3 ; the top section of column 2 is maintained at a temperature just below 71C. and an acrylonitrile/water azeotrope is obtained as distillate, which is separated into two phases in decanter 12<SP>1</SP>. From the base of column 2 is withdrawn a mixture comprising water, acetonitrile and acrylonitrile ; and this mixture is freed from substantial quantities of water by distillation in column 6, the water being discharged through line 7. The distillate from column 6 flows through line 8 into column 9, wherein a temperature gradient of 71-76 C. is maintained between the top of the column and a level four-fifths down the column; and pure anhydrous acetonitrile is withdrawn from the base of the column through line 11. The distillate from column 9, comprising an azeotropic mixture of acrylonitrile and water plus traces of acetonitrile, is separated into two phases in decanter 12<SP>111</SP>, the aqueous phase being returned to column 6 via line 13, and the organic phase being returned to the feed line 1 via line 10. If hydrocyanic acid is also present as an impurity in the feed, it distils over in the first stage with the acrylonitrile/ water azeotrope, from which it can be removed by further distillation. An embodiment is also described wherein an aqueous solution of acetonitrile is withdrawn from the side of the first column, and water is discharged from the base. Specification 719,911 is referred to.
