Title: Improvements in and relating to gas filled electrical discharge lamps and tubes
IPC: H01J61/32
Filed: 1933-06-22
Abstract: 421,537. Discharge lamps. FROM, V. C., 122, Southampton Row, London. June 22, 1933, No. 12915. [Class 39 (i)] In a gaseous discharge lamp in which the tube is curved to bring the ends containing the electrodes close together in parallel relation so that they may be mounted in an ordinary plug to fit a two pin socket, the tube is bent in the form of a curve at a right or acute angle from the electrodes and encircles the latter. In the form shown in Fig. 2, the branches 1, 2 containing the electrode are bent at right angles at 3, 4 and again at 5, 6, the tube 7 being bent in circular shape to encircle the electrodes and then attached to the branches at 8, 9. The branches 1, 2 are mounted in a socket 10 having metal plugs 11, 12. In the form shown in Fig. 4, the connecting tube 7 comprises three parallel circularly bent portions connected by tubing 13, 14. Instead of the tubing 7, a curved coil with three or more convolutions may be used. Signs may be built up from an assembly of the lamps described above in a manner similar to known signs employing areas of plugged-in incandescent lamps.

Three conductors are used for selective calling between two terminal stations and a plurality of intermediate dependent stations C, D; one conductor includes a calling relay A in each intermediate station, a second includes a calling relay B in each terminal station, and the third connects like poles of the supply sources in the terminal stations, the opposite poles being connected to the first and second conductors at the terminal stations and keys being provided at each station for connecting the first and/or second conductors) to the third conductor. As shown, in a cable transmission system permitting communication between terminal stations and visitors, such as repair men, at normally unattended repeater stations, two phantom wires and one interstitial wire are used for calling. At each repeater station such as D the calling relay A is normally shunted by key contacts KA5 which are opened by a visitor so that the station may be called from a terminal station by operation at the terminal of a key KA1. Each repeater station has keys KA1 and KA2 for calling other repeater stations in either direction and keys-KA3 and KA4 for calling either terminal station. Each terminal station has a key KA2 for calling the other terminal station. The speech circuit extends over the usual engineering channel. A further development enabling signalling to take place through a terminal station to another system is described with reference to Fig. 2 (not shown).

Abstract: 675,858. Hardening photographic layers. GEVAERT PHOTO-PRODUCTEN, N.V. May 5, 1950 [May 17, 1949], No. 13144/49. Class 98 (ii). 2 : 3 - Dihalogeno - dioxane or 5 : 6 - alkyl, aryl or halogen derivatives thereof such as 2 : 3 : 5 : 6 - tetrachloro - dioxane or 5 : 6- diphenyl - 2 : 3 : 5 : 6 - tetrachloro - dioxane are incorporated into a gelatin containing photographic layer such as a negative or positive gelatino-silver halide emulsion layer or an anti-halation, anti-abrasion or intermediate layer. The hardening effect may be enhanced by incorporation, also, of a carbocyclic compound having at least one nuclear hydroxyl group such as resorcinol, phloroglucinol, salicylaldehyde or resorcylaldehyde; and the use of such carbocyclic compounds together with a dioxane derivative eliminates " post-hardening ". Incorporation of the dioxane derivative may be effected by mixing it with the coating solution for the layer to be hardened or with the gelatin used for preparing this solution, by bathing the layer, after coating, in an alcohol solution of the derivative, or by provision of an adjacent gelatin layer containing the derivative. The carbocyclic compound, when used, may be incorporated similarly. In example 1, 0.2 gram of 2 : 3- dichloro-dioxane is incorporated into a kilogram of silver halide gelatin emulsion. Example 2 specifies half this quantity of dioxane derivative together with 0.5 gram resercinol and 0.05 gram resorcylaldehyde.

Abstract: 1460709 Gas-liquid contact plate G G HESELDEN 21 Dec 1973 [21 Sept 1972] 13253/72 Heading B1R Distillation or absorption columns comprise a plate or tray so arranged that at all operative rates of flow a series of horizontally spaced regions above the plate have little or no vapour rising through them compared with the intervening regions and thereby serve to stabilise the dispersion of down-flowing liquid in rising vapour by providing substantially quiescent regions through which the liquid can return to the floor of the tray. The quiescent regions can be obtained by using a plate or tray in which the holes are concentrated in parallel bands extending across the plate or tray in the general direction of flow of liquid between an underflow inlet weir and an overflow outlet weir or by providing pairs of substantially upright baffles above the tray substantially parallel to the general direction of liquid flow over the plate. Each pair of baffles can comprise two metal sheets which diverge away from the plate and can be located above unperforated bands of the trays. Fig. 2b illustrates a series of baffles made by perforating and bending a single sheet of metal and which can be fixed to the plate or tray by spot welding or by tabs which extend through holes in the plate or tray. Deflectors (Figs. 3 and 6, not shown), can be provided at the tops of the baffles to assist the separation of liquid and gas from foam.

The stud 51 is mounted on a rotatable ring 49 which can be positioned either to close off the supply, as shown in the left-hand part of Fig. 1, or to supply gas to the housing by way of a bore 53. When the gas acts on the membrane 39, a collar 45 thereon moves into a recessed chamber 46 allowing the gas to pass through apertures 48 in the membrane 39 and to enter the vessel 1 around the ring 18 and by way of holes 10 in the socket 8. The liquid is forced up the pipe 9 and passes to a central bore in the gland 28 by way of aperture 14 below the plug 12 and holes 31 in the gland 28. In Fig. 1 the gland 28 and membrane 38 prevented from movement by the fixed plug 12, but in an alternative embodiment of connecting member on the vessel 1 in which the plug is formed as a valve head inside the ring 18 and the ring carries the rising pipe, the inner gland 28 is moved by the effect of gas pressure in the membrane 38 to act on the central valve head and the gland 27 moves the ring 18 as before. Other alternative embodiments of the connecting piece are also described in which the chamber 36 in which the central part of the membrane 38 moves is mounted inside the space between the two membranes, and in which the action of the membranes is enhanced by effectively reducing their areas by use of flexible skirts located around the glands 27, 28 and between the membranes and/or between the membrane 27 and the housing part 19. In this latter instance gas supply is by way of a conical valve seat in which a ball is held clear of the seat by part of a flexible collar on one of the membranes, the collar deflecting to allow the ball to close off the gas supply in the event of excessive gas pressure (Fig. 5, not shown).

The catalyst may contain additional metal or metals, for example selected from aluminium, copper, chromium and manganese, in an amount constituting not more than 20 weight per cent of the total weight of cobalt (as metal) and additional metal or metals. The catalyst may comprise inert carrier material, for example alumina, silica, diatomaceous earth or pumice; such supported catalyst may be prepared either by moulding a mixture of powdered cobalt oxide and powdered alumina and thereafter sintering and reducing the moulded product or by immersing carrier material in an aqueous solution of a watersoluble cobalt compound, for example cobalt nitrate, and thereafter drying, sintering and reducing the impregnated carrier material. Examples relate to catalyst prepared from cobalt oxide; metallic cobalt and cobalt hydroxide; cobalt oxide and alumina (Al constituting 20 weight per cent of Co+Al); cobalt oxide and copper oxide (Cu constituting 10 weight per cent of Co+Cu); and cobalt oxide, copper oxide and manganese oxide (Cu and Mn each constituting 5 weight per cent of Co+Cu+ Mn).
