Abstract: 129,998. Schultz, E. J. A., and Seghers, A. C. July 17, 1918, [Convention date]. Paper, metal, wood, and fibrous pipes and tubes.- Tubes of metal, pasteboard, &c. of various cross-sections such as are used for the frames of aeroplanes, automobiles, &c. are formed by coiling sheets upon themselves, or upon rods or tubes, the sheets being shaped in the form of closed curves as A<1>, a<1>, b<1>, m, c<1>, d<1>, D<1>, Fig. 2 or Fig. 4, which curves are drawn from the bending moment curves of the tubes required. The ordinates of the curves are proportional to the moment of inertia at each point of the tube. The coiled parts of the tube are connected by a suitable medium, and, if of metal, are soldered together by rolling the sheets in a bath of tin after scouring, or by previously tinning the sheets and re-heating in a bath of tin. Long tubes may be rolled from two sheets, e.g. from the sheet shown in Fig. 2 divided along the line m n, or in Fig. 4 along the line m p. In the former case; a triangular gusset o, m<1> p is used to overlap the junction of the divided tube sections, and the shapes of these may be medified somewhat as indicated by the dotted curved line passing through the point m<1>. As shown in Fig. 4, an extra piece J is rolled up to form the tube. Wires or strips may be embedded in the tubes.

Abstract: 719,669. Treating liquids with gases. KITTEL, W. July 15, 1952 [July 16, 1951], No. 17909/52. Class 55 (2). [Also in Group VI]  The plates of a column for effecting countercurrent contact between liquids and gases &c. have inclined gas apertures with outflow. direction aligned circumferentially of the column axis and liquid inlet and outlet means so disposed as to discharge an accelerated flow on to the plate and to cause it to flow in the same direction as the gas outflow apertures whereby a rotational flow of ,liquid is produced combined with a cavitation offset in the gas apertures. The plate structure of a contact column 12 comprises sector plates a. adjacent plates b with inclined apertures 10 having outflows aligned circumferentially of the column axis followed by free spaces c above other sectors a, Fig. 3, representing a developed vertical section round the column. Partitions d have a gap through which liquid -flows from plates a at increased speed over the apertures 10 producing a cavitation effect before passing over the partitions d into the next lower collecting sectors a in which the speed is retarded. In a modincation the apertured section comprises a hexagonal band between outer and inner zones traversed in zig-zag fashion by the descending liquid which thus flows outwardly and inwardly over alternate vapertured plates. Guide blades at the base of the partitions are arranged to impart a swirl in the same direction as the Now of gas through the apertures. Another construction provides apertured plates of ring formation with the aperture rows extending radially.

Title: Improvements in the production of artificial materials by wet spinning processes from solutions of organic derivatives of cellulose
IPC: D01F2/28
Filed: 1931-06-23
Abstract: In wet-spinning processes for the production of artificial filaments, threads, ribbons, films, &c. from organic derivatives of cellulose, coagulation is effected by means of coagulating media of high solvent power and containing lower aliphatic acids together with relatively high boiling solvents for the cellulose derivative.  The coagulating medium may also contain a soluble salt or other substance capable of reducing the solubility of the aliphatic acid and/or relatively high boiling solvent in the non-solvent constituent of the coagulating medium, examples of such substances being sodium acetate (and soluble salts in general), sugars, and other polyhydric alcohols.  The lustre of the products may be modified by modifying the relative proportions of the aliphatic acid and the salt or the like in the coagulating medium.  Suitable relatively high boiling solvents mentioned are ethyl lactate, diacetone alcohol, diethyl tartrate, mono- and diacetin, glycol monoacetate, glycol diacetate, and methyl glycol monoacetate.  Solvents or swelling agents of low boiling point may also be contained, in the coagulating medium, e.g. acetone, acetaldehyde, formaldehyde, and alcohol.  Water is preferred as the nonsolvent constituent of the coagulating medium, but benzene, toluene, and other liquid hydrocarbons are also mentioned.  The spinning solution itself may contain any desired solvent and/or nonsolvent and/or high boiling solvent for the cellulose derivative. The solvents retained in or upon the filaments &c. after emergence from the coagulating medium may be removed by suitable means, or if desired, a certain proportion of such solvents may be allowed to remain therein.  The process permits of the application of a relatively high draw-down or stretch to the materials, so that very fine filaments are obtained.  Examples are given in which solutions of cellulose acetate are spun into baths containing acetic acid, ethyl lactate and sodium acetate. Specifications 332,187, 338,490, [Class 2 (ii), Cellulose &c.], 341,148, 341,897, 343,949, 346,678, 346,793, 366,110, 371,343, 375,424, and 378,858 are referred to.

Abstract: 458,798. Multiplex wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Holmes, R. S.; 164, Merion Avenue, Haddonfield, New Jersey, U.S.A.) June 28, 1935, No. 18544. Convention date, June 28, 1934. [Class 40 (v)] A radio receiver, adapted to receive simultaneously two signal modulated carrier waves, is provided with means to render it inoperative to reproduce either except when both carrier waves are received. The control may be operated by utilizing a beat frequency of the two carriers or by noise suppressing circuits of the kind used for automatic volume control. Fig. 3 shows a supersonic heterodyne receiver in which the frequency of oscillator 9 and the carrier frequencies used for sound and vision are so chosen that a single oscillator gives the respective intermediate frequencies which are applied to amplifiers 13, 15. The signal receiving circuits and the local oscillator are preferably gang controlled. Part of the amplifier output is applied to a double grid valve 85 so that when both carriers are received a beat frequency is produced which is rectified to apply negative bias to the grid of valve 61. This reduces the anode current through resistance 79 and removes a prohibitive bias from amplifying valves 23, 43 and renders these valves operative. A switch 92 may be provided to render the noise suppression valve inoperative. In a modification, Fig. 4 (not shown), the cathodes of the amplifiers and of the noise suppression valve are earthed and an alternating current anode supply is provided for the noise suppression valve the anode resistance which provides the grid bias for the amplifiers. Fig. 5 shows intermediate frequency amplifiers 133, 139 and automatic volume control valves 155, 183, for the two channels. Noise suppressor valves 233, 235 are also provided and the automatic volume control voltages are applied to the grids. The anode circuits are connected in parallel and include an alternating current supply 251 and a resistance 250 which controls bias of amplifying valves 159, 187. In a modification, Fig. 6 (not shown), diode detectors are used and give automatic volume control voltage in addition to serving as signal detectors. In this arrangement a double triode valve is used for noise suppression and the control voltage is applied to signal frequency amplifiers.

Abstract: 518,565. Gear pumps. DUNSMORE, A. C. June 27, 1938, No. 18940. [Class 110 (ii)] [Also in Groups XXXIV and XXIX] A multifeed lubricant distributer comprises a pair of closely-meshing gear wheels G1, G2 rotating in a closely-fitting casing C. Oil fed to the duct I is carried by the teeth Tl, T2 to a space F. Thence the oil divides into two streams and flows to bores in the trunnions E1, E2. These bores lead to radial bores Dl, D2 and axial bores Rl, R2. The cover S has. a plurality of outlets which communicate in succession with the bores R1, R2 as the gear wheels rotate, the outlets being connected to the points to be lubricated. The lubricator may have more than two gear wheels and the gears may be driven by the pressure of the oil entering at I or they may be driven mechanically. Instead of an axial distribution as shown; the trunnions may drive a cylindrical rotary distributor having radial outlet passages. A pointer driven by the gears may indicate the functioning of the lubricator. The lubricant outlets may have relief valves with or without indicating devices. In a modification the lubricant issuing from the outlets may act upon a piston which moves a smaller plunger todeliver lubricant to a point at increased pressure, the return stroke of the piston being effected under spring action.
