IPC: B60V1/16
Filed: 1970-05-18
Abstract: 1302716 Skirts for gas cushion vehicles SOC D'ETUDES ET DE DEVELOPMENT DES AEROGLISSEURS MARINS TERRESTRES ET AMPHIBIES 18 May 1970 [19 May 1969] 23961/70 Heading B7K [Also in Division E2] A skirt of a gas cushion vehicle comprises removable panels each having reinforcing material in the form of a network of flexible reinforcing members in reticular formation ending in the periphery of the panel, and having peripherally located attaching means 16 at the ends of the reinforcing members for detachably securing the panel in the skirt. In one embodiment, Fig. 3, a panel of a frusto-conical skirt is seen laid flat. A flexible fluid-tight wall 15 covers either side of a network of elastic reinforcing straps 13, 14 which may be connected where they cross by stitching 17 or by rivets to allow pivoting. There may be two walls, one each side of the straps, the walls being joined in the mesh of the straps. Closed rings 16 form attaching members by which the panels may be attached to adjacent panels or to a gas cushion vehicle. The lower rings may be attached to a lower panel to increase the depth of the skirt. The straps 14 may be folded back to form a double strap at the top, and the straps 13 may be similarly folded back from the sides. In another embodiment (Fig. 12, not shown) the straps (40, 41) are arranged diagonally with peripheral vertical and horizontal straps (13, 14). In a further embodiment (Fig. 13, not shown) there are vertical straps (not shown) and horizontal straps, each panel being connected to adjacent panels with closed hooks (6, Figs. 16-19, no shown, see Division E2). The hooks also connect an upper half (120a) of each panel to a gas cushion vehicle (1a) and a lower half (120b) to the upper half. Fluid tightness between panels and portions of panels is preserved by partial overlap of the or each flexible wall adjacent the rings (6) and hooks (16), Figs. 8 and 9 (not shown). Fluid tightness between the panels and the gas cushion vehicle is preserved by a drip flap (22, Fig. 7, not shown) depending from the vehicle and overlapping the top of the flexible walls. The panels may form a peripheral fluted skirt defining an enclosure round several discrete frusto-conical skirt-bounded cushions leakage from which feeds the enclosure (Fig. 1, not shown).

Abstract: 668,160. Identifying coverings for cables. LIVERPOOL ELECTRIC CABLE CO., Ltd. Sept. 30, 1950, No. 23981/50. Class 36. An electric cable having rubber or rubber-like insulation is provided with a homogeneous coating of multi-coloured lacquer produced by the complete or partial dissolution of distinctively coloured threads or strips disposed between a coating of coloured lacquer and an overall coating of clear lacquer. The lacquer employed may have a base of cellulose or natural rubber derivative, vinyl polymer or synthetic rubber, or a combination of such substances. In an example, a rubber-covered cable is coated with a lacquer of one colour around which is wound, in open helical formation, a thread of soluble, contrastingly coloured material. The cable is then passed through a solution of clear lacquer which contains a substance which can dissolve the material of which the thread is made. For example, if the thread is of cellulose acetate the clear lacquer solution will contain acetone.

Title: Gain control of valve amplifying systems
IPC: H03G7/02
Filed: 1938-08-16
Abstract: 506,128. Automatic volume control. STANDARD TELEPHONES & CABLES, Ltd. Aug. 16, 1938, No. 24139. Convention date, Sept. 23, 1937. [Class 40 (v)] A volume compression system of the in which the rectified output of an amplifier is applied as variable bias to the grid of the valve includes also means to limit the output to a predetermined level by a rectified voltage applied to another grid of the same valve. The output from a microphone 1 is applied over amplifier 3 to the control stage 5 and thence over amplifier 4 to the loudspeaker 2. The output from 5 is also passed over amplifier 8 to a pair of rectifiers 9, 31, the former providing a control bias varying with input amplitude and applied to the grid 14 which has a variable-mu characteristic. This bias is superposed on a steady bias derived from tapping 33 on resistor 23 ; tapping 34 on this resistor provides also a steady bias on the second control grid 15 of valve 5 which has a linear characteristic with sharp cut-off and thus acts as a limiter. On this steady bias on grid 15 is imposed a bias variable with signal amplitude derived from rectifier 31. The time constants of the two rectifiers may be varied by means of condensers 35, 37 and resistors 36, 38 respectively. In a modification, Fig. 1 (not shown), the rectified output from a single rectifier is applied to both grids 14, 15 of valve 5.

Abstract: 654.285. Carburetted water gas. HUMPHREYS & GLASGOW. Ltd. Sept. 16,1948, No. 24356. [Classes 55(i) and 55(ii)] Gases from a water gas generator enter the carburetting chamber of an "empty" type carburetter through a vertical pipe having in its walls slots or the like formed to give a tangential motion to the gases passing therethrough, so that the gases flow through the pipe and the carburetting chamber with a spinning motion. To suit the varying requirements of the blow and run phases, the degree of spinning motion may be varied. Figs. 1 and 2 show the top part of a down-flow carburetter comprising an empty oil spraying chamber a divided by a top wall b from an inlet chamber d which is connected by a tangentially entering pipe f to the generator The wall b has a central hole b<2> communicating with a vertical axial pipe c in chamber d. The wall of pipe c has tangential slots cx formed therein so that gases enter the pipe and pass through chamber a with a spinning motion. To vary this motion, the slots may be formed as shown in Fig. 3, and provided with vanes g which can be individually adjusted to increase or retard the motion. Alternatively, Fig. 7, the main inlet pipe f may be branched one pipe f<1> entering the top end of pipe c which is provided with tangential slots as in Fig. 2, the other leading radially into chamber d. By manipulation of valves g<5> and g<6> the spinning motion of the gases can be varied from zero to a maximum. In Figs. 4 to 6 and 8 to 11 (not shown) other arrangements of inlet pipes and movable vanes are shown. Specifications 654,280. 654,281. 654,282, 654,283 and 654,284 are referred to.
