Title: Theatrical procedure and stage settling therefor
IPC: A63J5/02
Filed: 1960-10-05
Abstract: 889,681. Lighting effects. ALSWANG, R. Oct. 5, 1960 [March 23, 1960], No. 34064/60. Class 132(1) In a theatrical stage setting, a motion picture screen comprises front and rear layers, the front layer 11 being composed of scrim and the rear layer 12 being composed of heavy but translucent material, the rear layer having a highly light reflective front face and bearing on its rear face a set design composed of translucent coating material, the design being invisible from the front except when the rear layer is lighted from the back, whereby rapid fading of a motion picture projected on to the screen from the front coupled on one side with a rapid aceration of back lighting 16 on to the set design, and vice versa can produce a dissolve between motion picture and live stage. To allow live action to take place between the layers the rear layer may be rapidly moved from close behind the front layer to a retracted position. The fornt layer may be removed edgewise and a further intermediate opaque drop 13 may be provided which is also removable edgewise from between the two layers. The invention also comprises a theatrical procedure which allows the creation of a dissolve between motion picture and live stage, which consists in projecting a motion picture on to the front face of a screen of translucent material, providing on the rear face of the screen a set design composed of translucent coating material and identical in size and design with a scene of the motion picture and co-ordinating the projections of the scene with simultaneous rapid fade out of the motion picture and back lighting of the screen and vice versa.

Abstract: 1330367 Selective printing INTERNATIONAL BUSINESS MACHINES CORP 21 July 1971 [3 Aug 1970] 34095/71 Heading B6F A carrier 16 for a print wheel is driven incrementally in letter-spacing direction by a reciprocable slidable rack 70 carried by a carrier support shaft 12. A latch (50, Figs. 3, 4) on the carrier 16 engages the rack 70, and a further latch (100) engages fixed teeth 66, 69 on the shaft 12 and defining a fixed rack in order to prevent reverse feed under bias of a spring 20 tensioned during letter spacing movement. The rack 70 is reciprocated by a solenoid 110. Carrier return is initiated by a solenoid 118 which acts on a lever 138 to lift a link 152 whereby the shaft 12 is rotated to disengage the latches from their respective racks. A spring-urged latch 32 holds the link in elevated position until a projection 28 on the carrier 16 strikes a projection 30 on the latch 32 to disengage same from link 152 and permit the shaft 12 to rotate into normal position. A dash-pot 22, 22a damps the motion of the carrier when returned.

Title: Improvements in or relating to processes for the treatment of beryllium ores
IPC: C22B35/00
Filed: 1936-12-18
Abstract: Beryllium is extracted from its ores by heating the ore with at least an equal weight for example, up to three times the weight, of a carbonaceous material, e.g. low temperature carbonization coke or powdered coal with a low ash content, in sulphur vapour and/or a gaseous or vaporized non-metallic sulphur compound such as carbon bisulphide or sulphuretted hydrogen, to a temperature of about 900 to 1200 DEG  C., then heating the mixture of beryllium and other sulphides so formed with hydrochloric acid gas or chlorine to convert the sulphides into the chlorides, thereupon separating the beryllium chloride from the other chlorides, and finally subjecting the beryllium chloride to a treatment for the production of the metal. The product of the sulphidizing operation consists, in the case of a beryl ore, mainly of beryllium, aluminium and silicon sulphides and silicon carbide. The treatment with hydrochloric acid gas or chlorine may be effected at 800-900 DEG  C., sulphuretted hydrogen or sulphur, which may be re-employed in the process, being also formed.  The residue of beryllium chloride left on distillation of the aluminium chloride and silicon tetrachloride may be distilled to purify it before being treated for the extraction of beryllium, or it may immediately be converted into beryllium sulphide from which metallic beryllium is obtained by the processes disclosed in Specifications 482,467; and 482,468, [Group XXXVI].ALSO:Beryllium ores are treated for the production of beryllium chloride from which metallic beryllium is obtained, for example, by conversion of the chloride into the sulphide, and the production of the metal therefrom according to the process disclosed in Specification 482,467.

Title: Improvements in rail weighbridges
IPC: G01G19/04
Filed: 1947-12-30
Abstract: 641,993. Rail joints. WIRTH, A. Dec. 30, 1947, No. 34889. Convention date, Nov. 15, 1941. [Class 104 (ii)] [Also in Group XVIII] In a railway weighbridge the gaps B between the incoming track rails 3 and the weighbridge rails 1 are bridged by a plate 17 which is loosely secured by members 15 to the rail supports 4, and is outwardly curved so that it takes the weight of the truck when it passes over said gap. The members 15 are constructed to allow the plates 17 a limited amount of lateral and longitudinal play and yet prevent them from jumping out. The bottom of each plate 17 is supported on cylindrical members 20 which determine the position of the top of said plate and are replaceable by others of varying size to allow for wear adjustment. Each rail is held from lateral movement by plates 7, 8 which allow a limited amount of vertical movement of the loaded rail and also longitudinal heat expansion which is limited by stops 23. In modifications (not shown) the plate 17 may be replaced by a length of rail of smaller section, or the plate may have a flat top surface and, at the gap B, the rails are curved to allow the plate to support the loads as before. When the invention is applied to narrow gauge tracks, to ensure that the wheel profile is engaged by the plates the rail head is cut away as shown in plan in Fig. 7.

Each play piece is a paper or cardboard model of a motor car 13 or pedestrian 15 on the base of which is an armature 14 ; this armature may be magnetized or non-magnetized. The playing surface of paper, card, celluloid or linen is attached to a frame 2 having pivoted supporting legs 3.. The legs may, however, be formed of spring steel wire inserted into the ends of frame 2. The device may be used as a race game, two motor cars 13 of different colour starting from one garage 12, one following the full-line course a and the other the dotted line course b. In another application, the board represents a railway and associated buildings and the play pieces are railway locomotives and carriages. In this case the raised obstructions are cuttings, fields, farms, &c. and the additional upstanding structures are stations, bridges, signal boxes. The armatures may be extended beyond the ends of the play pieces so that several play pieces may be coupled magnetically and drawn along together. The apparatus may be used as a toy or for educational or advertising purposes.
