Patent GB-415554-A (GB)
Title: Improvements in and relating to gas discharge devices
IPC: H01J65/00
Filed: 1933-07-01
Abstract: 415,554. Discharge lamps. LEPEL, E. VON, 39, West 60th Street, New York, U.S.A. July 1, 1933, No. 18721. Convention date, July 1, 1932. [Class 39 (i).] In an electric discharge lamp without internal electrodes, which operates with a gas mixed with metal vapour, the provision of a separate condensing vessel connected to the discharge vessel by pipes is avoided by constructing, or providing, the discharge vessel with projections in such manner that at least one hollow space disposed outside the zone encompassed by the exciting coil is obtained in which the metal, such as mercury or the like, is condensed, due to the hollow space or spaces being cooler than the main discharge space. The example shows a discharge vessel 6, which may be of spherical or other shape, provided with projections 7, 8 of comparatively small cross section disposed outside the zone encompassed by the exciting coil 4, the projection 8 being secured within a metal cap which is screwed into a socket 9 in a reflector R and conducts heat away from the wall of the condensation chamber, and also forms an electromagnetic screen. The mercury within the projections 7, 8 remains comparatively cool and the quantity does not require such precise measurement as when the mercury is introduced into the discharge vessel itself.

Filed: 1934-06-25
Abstract: 440,212. Rotary engines. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G., and REAVELY, T. C., Scotswood Works, Newcastle-on-Tyne. June 25, 1934, No. 18735. [Class 110 (ii)] A rotary engine of the type shown, which may be used for driving a pneumatic drill, is driven by a compressed fluid, which also is used to impel the vanes E radially outward, the two fluid streams being kept separate, or not. Inlet and exhaust arc-shaped ports 4, 5, asymmetrically arranged in the stator end walls, connect with axial bores 2 in the rotor, and fluid is led along passages 3, 1, to below the vanes, or exhausted therefrom. Compressed fluid supply for both of the above purposes, enters a passage 12 and passes to either passage 6a, or 7a, dependent upon the direction of rotation of the rotor B. A sleeve H has a channel 13, which controls fluid supply between chambers 11, 10, and also is connected to a valve F. Working fluid enters one or other ports 14, 15, to drive the vanes, and is exhausted through one or other ports 16, 17, and the inlet port not being used such as 14 in Fig. 2. The two exhaust streams pass through an outlet 21. In a modification the fluid used to project the vanes radially may be afterwards used to drive the vanes and rotor. For this purpose additional concentric stator ports are arranged parallel with, and of equal length to, the original stator ports. Additional ports are also supplied in the rotor. Specification 440,479 is referred to,

Title: Improvements in the production of regenerated cellulose filaments from viscose and apparatus therefor
IPC: D01D5/06
Filed: 1964-05-07
Abstract: 1,025,217. Apparatus for wet spinning viscose. SNIA VISCOSA SOC. NAZIONALE INDUSTRIE APPLICAZIONI VISCOSA. May 7, 1964 [May 7, 1963], No. 18996/64. Heading B5B. An apparatus for wet spinning viscose comprises a trough for containing an aqueous solution of sulphuric acid containing not more than 70 grams of sulphuric acid per litre, the trough being divided by a partition wall into a first part containing a spinneret and an inlet for the coagulating liquid and a second part provided with an overflow outlet determining the level of the coagulating liquid in the second part. A straight tube open at both ends and coaxial with the spinneret passes through the wall and is mounted in a hole in the wall in such a manner that no liquid leaks through the wall but the tube can be rotated about its axis from one position to another when required. The outlet end of the tube in the second part of the bath is bent so that when the bent portion of the tube is pointing upwards the outlet of the tube is at the same level as that of the liquid in the first portion of the bath, or at a somewhat higher level and the rate of gravitational flow of liquid through the tube ceases or is relatively slow. On the other hand, when the tube is rotated so that its outlet is at the same level as its inlet, the rate of gravitational flow of coagulating liquid through the tube is relatively high, since the liquid in the first portion of the bath is maintained at a higher level than that of the liquid in the second portion of the bath. The tube is rotated into the second position when spinning is initiated so that the freshly extruded filaments are carried by the rapid flow of liquid into and through the tube, threading up of the apparatus thus being facilitated. After the threading up operation is completed and normal spinning is to be started, the tube is rotated into the first position, so that gravitational flow of liquid through the tube ceases or is very slow and the liquid in the tube tends to retard the travel of the filaments through the tube. Stretching of the filaments during their coagulation is thus effected and most or all of the slow passage of the liquid through the tube is solely due to the drag of the filaments on the liquid in the tube and the transporting of liquid adhering to the filaments.

IPC: C08F10/00
Filed: 1959-06-04
Abstract: Polymers are prepared from dimethyl-orthodivinylbenzene or other ortho-divinylbenzene whose preparation is described (see Group IV (b)).  It may be copolymerised with styrene, allyl and methallyl esters of carboxylic acids, vinyl ethers and ketones and butadienes.

In an example, ortho-divinylbenzene is polymerised in chlorobenzone at 132 DEG  C. in the presence of t-butyl peroxide.  Infra-red analysis shows only one of the vinyl groups was involved in the polymerisation.ALSO:The Specification comprises dimethyl-ortho-divinylbenzenes and the method of preparing these and other ortho-divinylbenzenes by contacting an acetylene and divinylacetylene with a catalyst prepared by mixing (1) a hydride or organo-metallic compound of a Group I-III metal and (2) a compound of a transition metal of Group IV-VIII.  The acetylene may have the formula R - C­ C - R1 where R and R1 are hydrogen, C - C10 alkyl, up to C10 aryl or up to C7 cycloalkyl.

Abstract: 614,033. Bridge andlike piers. DISNEY, C. P. July 1, 1946, No. 19651. [Class 68 (ii)] [Also in Group X] Bridge and like piers are constructed by erecting a form to extend from the foundation rock to above water level, securing vertical tubes of similar extension in desired arrangement within the form, filling the form around the tubes with concrete, operating drills through the tubes to drill holes in the rock bed, and sinking load supporting piles in the tubes into the holes. As shown, a framework to guide the' wall piling 5 is formed of spaced columns 3 welded between paired bands 1, 2, the pairs of bands being spaced vertically and having braces 10, 11, lateral braces, and columns 9 vertically slidable in guides 8, by which the seating of the framework is adjusted. The columns 3 and 9 have piling sections 6, 7 welded'thereto which interlock with the piling 5. Crossed bars 12 &c. are arranged between the braces 10, 11 to form squares which receive steel tubes 15, the lower ends of which may be plugged. The sheet piling 5 is driven to bed-rock, and the enclosure surrounding the tubes filled with concrete. Rock drilling tools are lowered through the tubes 15, and holes' 16 bored to the required depth. Steel piles 17 are then lowered through the tubes 15, driven into the holes 16 and the tubes filled with concrete. The upper end of the pier may be built up around the projecting ends of the piles by applying concrete, or a lattice as shown in Fig. 12.
