IPC: B07B1/62
Filed: 1957-03-15
Abstract: 816,623. Sifting apparatus. BURSTLEIN, E. M., and SOC. DES ACIERIES DE LONGWY. March 15, 1957 [July 21, 1956], No. 8672/57. Class 117 A screen, electrically heated by the flow of current therethrough, is divided into an even number of panels, one half of which is supplied from one phase of a two-phase source, and the other half is fed from the other phase. The source may comprise a 3 to 2 phase converting transformer fed from a 3 phase network, and the secondary voltage may be adjustable up to a maximum of 24 volts. Panels in each group may be connected in series, parallel, or series-parallel relation. To provide differential heating of the two groups the impedances thereof may be different or the groups may be supplied with different voltages. To provide a balanced differential heating of the groups, the impedance per unit area of one group may differ from that of the other, whilst the lengths of the panels in each group may also differ so that the overall impedance of both groups is the same. A high current connection to a screen gauze 46 is shown in Figs. 7 and 8, and includes a plate 43 forming part of means for stretching the the screen and compensating for the expansion thereof, slidably mounted over a guide secured to the screen frame. Threaded rods 44 arranged in two parallel rows are secured to the plate and project through a bus-bar 45, the gauze 46 and a clamping plate 47, and nuts 41 secure the assembly. Fig. 10 shows an electrical connection between adjacent gauze panels, and includes a plate 52 insulated from the screen frame and attached thereto by two rows of threaded rods 53 and nuts. Threaded rods 58, in two parallel rows, pass through a bus-bar 45, the two gauze panels 46 and 59 and a clamping plate 42. Nuts 41 secure the assembly. In both of the electrical connections described nut locking means 42 are provided. An intermediate support for large screens consists of a cross-member 60, Fig. 11, extending between the sides of the screen frame and carrying a channel shaped element 61 in which is resiliently secured an insulating member 62 e.g. of ceramic, held by nuts and bolts 65, 66.

Patent GB-492676-A (GB)
Title: Improvements relating to apparatus for use in conveying powdered or granular material in a quasi-liquid state
IPC: B65G53/22
Filed: 1937-03-24
Abstract: 492,676. Pneumatic conveyers; delivering material from hoppers. JORGENSEN, M. VOGEL-. March 24, 1937, No. 8717. [Class 78 (i)] In systems for conveying powdered or granular material in a quasi-liquid state by compressed air of the kind in which the material is admitted to a container and the reafter expelled from it by compressed air the valves regulating the admission of air and material to the container are controlled by the pressure of the material on a plate pivotally mounted in the container. The plate 4, Fig. 1, is attached to a bell-crank lever 5, 7 and is arranged behind an aperture 30 in a tube 28 in order that pressure may be exerted by the material only on its right-hand face. The lever 5, 7 is pivoted at 6, and its weighted horizontal arm is connected by a rod 9 to a slide valve mounted in a casing 10. When the plate 4 is displaced by the material, the valve is in its highest position, and compressed air is cut off from the pipe 12a. This allows the springs 32, 33 to close the valves 3, 19 in the inlet pipe 2 and top of the casing 1, respectively. At the same time compressed air passes through the pipe 12b to the cylinder 18 and opens a valve 16 which allows compressed air to pass to a perforated ring 20 and a distributer 21 for converting the material into a quasi-liquid state and forcing it from the container through a discharge pipe 22. As the level of the material falls, the plate 4 does not return to the position shown until a similar plate 23 near the bottom of the container is uncovered. When this occurs, a slide valve in the casing 27 is moved to admit compressed air to a pipe 35 and this effects the release of a latch holding the rod 9 in the raised position. The return of the plate 4 to the position shown effects the opening of the valves 3, 19 and the closing of the valve 16, with the result that the container again fills with the material. Two containers provided with plates 4 only may be connected so that the movement of the plate in one to effect its discharge may cause the filling of the other. The two containers may each have plates 4, 23, and in this case means are provided for preventing the commencement of the discharge of either container until the other is empty. The valves may be actuated electromagnetically instead of pneumatically.

Title: Improvements in or relating to television cameras
IPC: H04N5/225
Filed: 1954-03-25
Abstract: 754,381. Television cameras. FERNSEH GES. March 25, 1954 [April 4, 1953], No. 8747/54. Class 40 (3). For focusing a television camera, the shaft 5 of the rotatable lens turret 4 is mounted for free axial movement in bearings 6, 7 and is coupled through a lever 8 rocking about a pivot 14 to a sliding carriage 10 supporting the pick-up tube 9 and associated apparatus. The lever is so proportioned that, when the camera is tilted, the moments about pivot 14 due to the lens turret and pick-up tube assembly at least partly balance and the focusing of the camera, which is effected by rack and pinion device 12, 13, remains free. In a modification, Figs. 2 and 3 (not shown), the focusing control 11 is arranged so that in certain positions, for example the infinity position, an axial displacement of the control disengages lever 8 from carriage 10 to lock the axial position of shaft 5. This facility is employed when the camera is operated in the horizontal position. The focusing is effected only by displacement of the pick-up tube with a consequent greater movement of the focus control and increased accuracy of adjustment.

[Also in Group XL(c)] A screening and cooling device for thermionic valves comprises a tubular sleeve 1 of metallic braiding or mesh, which is stretched longitudinally by a spring 8 so that it contracts diametrically to grip the enclosed valve 10. At the lower end, the braiding is secured to a member 4 which can be attached to a valve socket, or a chassis. At the upper end, an end member 2 clamps the braiding sleeve to the end turn of the compression spring 8. As shown, the spring bears against the top of of the valve 10, but alternatively the spring may be completely outside the sleeve 1, bearing against the lower attachment member 4. The braiding may be of copper or aluminium, and the spring may be actually woven into it while in a soft state, and then hardened by treatment which renders it resilient without affecting the braiding. The sleeve may be surrounded by an ordinary screening can, Fig. 6 (not shown).

Title: Process for the production of toluidine derivatives
Filed: 1938-03-29
Abstract: 513,473. Thiocyano derivatives. MANCHESTER OXIDE CO., Ltd., CLAYTON, J. H. and BANN, B. March 29, 1938, Nos. 9524/38, 9525/38, 23157/38, 4090/39 and 4091/39. [Class 2 (iii)] Thiocyano derivatives' of aniline and ortho toluidine are prepared by treatment of the amine in solution with a solution of an inorganic thiocyanate and a cupric salt, the reaction medium from which the product has to be recovered being mainly water. It is stated that the cupric thiocyanate will react preferably with the organic compound before reacting with the water. Thiocyanates mentioned include sodium and ammoniumu thiocyanates. It is preferred to add the cupric salt gradually so that the thiocyanogen may be consumed as it is produced. It is also preferred that a small quantity of acid be added to the aqueous solution of the thiocyanate at the beginning of the reaction. An excess of acid, however, is avoided. The acid may also be added in admixture with the cupric salt. A particularly suitable acid is oxalic acid, but sulphuric or hydrochloric acid may also be used. In some cases the addition of a water miscible solvent such as alcohol assists the reaction to proceed smoothly. It may be added in amounts up to 30 per cent. but the water must always be in large excess. The cupric salt may if desired be added as a finely ground powder instead of in solution. Dispersing agents such as those known under the Registered Trade Mark " Igepon " may be added to assist the dispersion of the organic compound in the thiocyanate. In examples (1) aniline is dissolved in an aqueous solution of sodium thiocyanate and an aqueous solution of copper sulphate stirred in slowly. The reaction mixture is kept at 60‹C. for half-an-hour, poured into a large amount of water, filtered and the filtrate neutralized with sodium carbonate to give para-thiocyanoaniline. (2) Aniline and an aqueous solution of copper sulphate are simultaneously run into an aqueous solution of sodium thiocyanate and the reaction solution worked up as above to give the same product. (3) An aqueous solution of copper sulphate and an alcoholic solution of sodium thiosulphate are simultaneously added to an alcoholic solution of aniline and the reaction mixture worked up as before. (4) Orthotoluidine and an aqueous solution of copper sulphate are simultaneously run into an aqueous solution cf sodium thiocyanate and the reaction solution worked up to give parathiocyano-ortho-toluidine. (5) Aqueous solutions of copper sulphate and sodium thiosulphate are added to an alcoholic solution of ortho-toluidine and the product worked up as before. (6) Ortho-toluidine is added to a dilute sulphuric acid solution of sodium thiosulphate. An aqueous solution of copper sulphate is then added slowly and the product worked up as before. German Specification 579,818 is referred to.
