Abstract: 944,327. Gibs. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 13, 1960 [June 12, 1959], No. 20227/59. Heading F2H. [Also in Division F1] A fir-tree or otherwise undercut slot 6 formed in a turbine &c. rotor 5 has a groove 8 at its radially inner end to receive a blade root 7. A blade-retaining bar 1 has upstanding legs 3 at the ends spaced apart a distance equal to the axial length of the blade root 7, one or both of the legs 3 being shaped so that when the bar is fitted over the inner end of the blade root 7 it can be inserted with the blade root into the slot 6. The bar 1 is then moved circumferentially about the axis of the rotor until one of its sides contacts a side of the groove 8 such that the upstanding legs 3 overlap the rotor 5 adjacent to the slot. A locking bar 10 having one bent end is inserted between the retaining bar 1 and the exposed side of the groove 8 filling the gap 9, and the remaining end of the bar 10 is bent to restrict its axial movement and also circumferential movement of the bar which, by its position, restricts axial movement of the blade root. The legs 3 of the retaining bar 1 may be symmetrical so that the bar may be inserted from either axial end of the disc or moved in either clockwise or anticlockwise direction in the plane of the disc, or alternatively one end 3 need not be profiled but could be left rectangular. The locking bar 10 may comprise two legs spaced apart a distance equal to the spacing of the blade roots and joined together by a yoke, being similar to a locking plate described in Specification 944,326.

Title: Improvements in or relating to a method of forming a photoemissive surface
Inventor: CASSMAN HARRY
IPC: H01J9/12
Filed: 1957-06-26
Abstract: 892,504. Cathode materials and processing. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 18, 1958 [June 26, 1957], No. 20230/57. Class 39(1) In forming a photo-emissive surface comprising antimony sensitized with at least two different alkali metals, only the final metal is evaporated on to the antimony in such quantity that the sensitivity reaches a peak value. In a preferred embodiment, the antimony surface is sensitized with sodium and potassium, and finally with caesium. Fig. 1 shows how the process is carried out in the manufacture of a television pick-up tube of the cathode potential stabilized type. The surface is formed on an insulating sheet 10 which is backed by a transparent signal plate 9. Antimony is evaporated from a heated pellet 13, and passes through a mesh 19 to form a mosaic on the sheet 10. The coil 13 is then retracted through the sidetube 11, which is also the exhaust connection; a small quantity of sodium is driven in from a second side-tube 17 while the device is baked and the exhaust tube 11 is sealed off between the auxiliary side-tubes 14 and 15. The mesh 19 is now dislodged from the antimony surface by shaking, as described in Specification 740,751. The envelope 1 is again connected to the exhaust pump by sealing together tubes 14 and 15, tube 14 being closed by a pip 14a which is not broken until a vacuum has been attained on its outer side. Potassium is now admitted from a third side-tube, the device baked, and further sodium admitted with further baking. In each of these cases the sensitivity reached is only a fraction of the peak value. Finally, caesium is admitted from a fourth side-tube until the sensitivity of the mosaic elements passes its peak value, and is restored thereto by baking off the excess caesium. Oxygen may be admitted at this stage to obtain a further increase in sensitivity. Lithium and rubidium may also be used as the alkali metals, and other devices such as photocells or photomultipliers may have a sensitized surface prepared in the same way.

Title: Improvements in upholstery fibres
Inventor: HAND JOHN
IPC: D02G1/02
Filed: 1950-08-24
Abstract: Stuffing or padding material for use in upholstery is prepared by twisting or plaiting fibres consisting of animal hair, e.g. horse or pig's hair, into a rope, whereby a curl is imparted to the fibres, treating the rope with a liquid or gaseous setting agent which reacts chemically with the fibres and sets the curl, air between the fibres being removed by suction prior to the treatment with the setting agent, if gaseous, or either prior to or simultaneously with the treatment if the setting agent is a liquid, fixing the curl by the removal or neutralization of any residual setting agent remaining on the fibres and finally untwisting the fibres.  Specified setting agents are thioglycolic acid, alkali metal and ammonium thioglycolates, sulphides, e.g. ammonium sulphide, and alkali metal hydroxides, carbonates, sulphites and borates, which are employed in aqueous solution, that of ammonium thioglycolate preferably having a pH of 9-10.  A gaseous setting agent, e.g. hydrogen sulphide, may also be employed.  The fixing operation may be effected by washing or, if the setting agent is volatile, by evaporation.  Alternatively chemical reaction or heat may arrest the action of the setting agent. For example, if the setting agent is alkaline or is a reducing agent, then the fixing agent may be acidic or an oxidizing agent respectively, suitable oxidizing agents being hydrogen peroxide, sodium hypochlorite and sodium bromate.  Air between the fibres may be removed by suction prior to or during the application of the fixing agent.  The curled fibres may finally be coated with rubber to form rubberized hair or attached to a canvas backing, and the fixing agent may be added to the rubber coating composition.  The treated fibres may be used in the construction of upholstery pads produced by the method of Specification 738,565.  According to both Provisional Specifications, the fibres may be wet with setting agent prior to twisting into a rope.
