Abstract: 317,450. British Tabulating Machine Co., Ltd., (Assignees of Mills, A. W.). Aug. 16, 1928, [Convention date]. Type-bar machines; hammer-impression arrangements.-In machines comprising means for traversing a set of type-bars past the printing line and detents for differentially arresting the type-bars, the traversing-means is arranged to move the type-bars for impression, the usual separate impression-hammers being dispensed with. As applied to the record-card controlled statistical machine described in Specifications 183,867, [Class 106 (i), Calculating &c.], and 247,200, the type-bars 30 Fig. 2, are pivoted to loose arms 28 on a shaft 23 and have fingers 33 which normally engage notches 26 in arms 24 fast on the shaft. Extensions 40 of the type-bars. are connected by links 41 to rocking arms 42 formed with racks co-operating with detents 43 which normally engage latches 44 connected to the armatures of magnets 11. The shaft 23 is rocked by means of a shaft 20, and the magnets are selectively energised under control of the record cards. At each operation the arms 24 traverse the type-bars past the platen 50 and when the magnets are energised the racks and type-bars are differentially arrested by the detents 43. Thereupon the arms 24 over-run the arms 28 and the notches 26 co-operate with the fingers 33 to move forwards the type-bars for impression of the selected types. On return of the arms 24 lips 27 thereon engage the fingers and return the type-bars and arms 28, 42, and springs 34 cause the fingers to enter the notches. The detents are re-engaged with the latches by means of cams 51 on the racks.

Abstract: 1431167 Cable joint cover RAYCHEM SA NV 7 Sept 1973 [8 Sept 1972 25 May 1973] 41860/72 and 25199/73 Heading H2E In a cover for a cable splice, rigid tube 3, either slit or in two parts 3, 3a optionally hinged, is fitted possibly by bayonet slots to rigid support rings 4, split or pre-fitted on cable; parts 3, 3a, 4 may be of metal or insulating material. Dilated heat-shrinkable sleeve 1 is coated with adhesive meltable sealant 5 preferably non- bonding to 3, 3a. Laminar comb-like prong assembly, of, e.g. Al, (Fig. 5, not shown), may be fitted longitudinally outward of rings 4, sleeve 1 then being extended beyond the prongs with sealant only from their midpoints outward (Fig. 6, not shown). On heating, sleeve 1 shrinks as in Fig. 2, gripping tightly tube 3, 3a and becoming sealed to cable sheaths 8 and to the ends of rings 4 or to the prongs, which smooth out the radial step (Fig. 7, not shown). After a joint cover has been opened neat its centre section only, the unsealed part of sleeve 1 may be removed, to be replaced by a new short heat shrinkable sleeve (Fig. 3, not shown). If the whole cover has been opened the sealed parts of sleeve 1 may be removed by heat softening of the sealant, after which a new sleeve 1 may be fitted (Fig. 4, not shown). In both methods the sleeve 1 is made split with lipped edges, closed after emplacement by a C strip (as in Specification 1,155,470) before heat shrinking. Sealant is applied over the whole length of the replacement sleeve, and is melted when heat is applied to shrink this sleeve.

Filed: 1932-09-12
Abstract: 395,537. Thermionic cathodes. LOEWE, S., 10, Wiesenweg, Steglitz, Berlin. Sept. 12, 1932, No. 25305. Convention date, Sept. 15, 1931. [Class 39 (i).] In a process for manufacturing highly emissive cathodes for rectifiers, amplifiers, or oscillation generators, a superficially oxidized cathode core, for example a tungsten wire, is introduced into an atmosphere of a highly emissive metal, such as barium, in a vacuum furnace'and heated to such a temperature that it reacts with the vapour to form a coating of barium oxide on the wire, after which the excess of vapour is removed, either by pumping or condensing, and a part of the wire is mounted as a cathode in a thermionic tube, heated to degasify it and convert any residual hydroxide or carbonate into the pure metal oxide, and finally provided with a coating of a highly emissive metal which is evaporated within the tube. The latter metal may be the same as that which is vaporized to form the oxide coating, but preferably consists of a light metal having a higher evaporation point. The filament material, preferably tungsten, may be coated initially with tungsten dioxide by introducing a loosely wound coil of the wire into a furnace containing hydrogen with a proportion of water.

Title: Improvements relating to high-voltage electric transformers
IPC: H01F27/32
Filed: 1952-10-09
Abstract: 709,361. Transformers. MOSERGLASER, CO. AKT.-GES. Oct. 9, 1952 [Oct. 9, 1951], No. 25353/52. Class 38(2) A high-voltage dry transformer of which the main insulation is solid, comprises a high voltage winding separated into two or more sections 3 on a core limb 1, each section being encased in solid insulation 6 adequate to withstand the full test voltage as well as the working voltage, and coated with an earthed metal layer. Adjacent sections may be joined by U-shaped connectors 9 with insulation 8 shaped at the ends to form plug and socket joints with the section insulation. The joints may contain a small amount of liquid insulation. In an alternative construction, Fig. 2, the joint insulation may be integral with that of one section and may plug into that of the section previously put in position, or, Fig. 3 (not shown), the connectors may leave and enter the sections through bushings of adequate size, not coated with a conducting layer, like those shown in Fig. 1 at 4 at the ends of the winding. The lowtension winding 2 may be inside and coaxial with the high-voltage winding, or in discs arranged between the highvoltage sections. There may be two highvoltage windings with interleaved sections, Fig. 4 (not shown). The insulation may be a concrete or a synthetic resin formed by polymerizing fluid monomeric material without evolution of a volatile material, e.g. "Araldite" (R.T.M.), a syn thetic rubber or elastomer, paper impregnated with such synthetic materials, or a polyvinyl chloride tape. A cooling fluid may be passed through a tube wound alongside the conductor, or through a hollow conductor, or through spaces 12 left between the winding and the insulation in the sections and connectors. Alternatively, each section or group of sections may be provided with a cooling jacket through which water or other fluid may pass, there being cavities in the section insulation to form channels in the stack of sections, Figs. 5, 6, 7 (not shown). In other modifications, the sections are provided with heat-dissipating fins which extend transverse to the plane in which the core limbs lie, or radially of the core carrying the sections, Figs. 8-10 (not shown). A cooling fluid between the sections may bear part of the voltage stress. Other cooling means are spraying the sections with a liquid which vaporizes, and circulating a medium through passages in the core.

Abstract: 892,317. Thermal regenerators. BRANDT, H., [trading as APPARATEBAU ROTHEMUHLE DR. BRANDT & CO.] Aug. 7, 1958 [Aug. 10, 1957], No. 25378/58. Class 64(1) A regenerative air heater comprises a matrix consisting of a cylindrical shell 5 divided by radial and cylindrical walls 7-10 into a plurality of chambers of equal radial length each divided by partitions 11 into cells containing packs 15 of heat transfer material of less axial length than the walls and partitions, each pack being formed with a plurality of fluid passages and comprising a plurality of plates, the mean width of each cell being approximately the same for all the chambers and the walls and partitions forming sealing surfaces co-operating with structures which conduct the heat exchanging fluids to and from the heat transfer material, means being provided to cause relative rotation between the matrix and the structures. The packs 15 of heat transfer material contain non-plane (e.g. corrugated) plates which are initially compressed and held in that condition by binding means which are removed after the pack in inserted in cell. The consequent expansion of the pack provides a friction tight fit of the pack within the cell and this may be supplemented by providing interlocking means between adjacent plates of the pack and between the outer plates of the pack and the cell walls. To prevent splaying of the plate pack when the binding is released, the end plates of the pack next to the cell walls may be made stiffer than the other plates. In addition the plates may be further secured against axial movement by cross bars 13 (Fig. 2) which are arranged to engage in slots 14 in the chamber walls 7 and partitions 11.
