[Class 40 (iv).] The armature of an electric pickup is formed of a split tube of spring material adapted to grip a needle inserted therein and provided with transversely disposed bearing members which co-operate with bearing members on the body of the pickup. As shown the needle holder comprises a tube 5, Fig. 4, of spring material such as sheet steel, provided with a slit 6 the internal diameter of the unstressed tube 5 being slightly less than that of the needle shank. The tube 5 is formed with tubular projections 7 forming trunnions which engage in bearing recesses 8 in the ends of the pole shoes 3, 4 of an electrical reproducer to form a pivotal axis for the tube, as shown in Figs. 1 and 3, wherein Fig. 3 is a plan view on the line 3-3 of Fig. 1. To limit the extent to which the needle 10 can be thrust into the tube 5 it contacts with a rubber block 11 which serves also to damp the oscillations of the needle and holder. According to a modified construction the tube 5 may be provided with one or more short slits at one or both ends, which ends may be frusto-conical in shape.

Abstract: 1,073,671. Gas turbine combustion chambers. H. TEVES, E.A. TEVES and M. TAUSEND [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK KOMM GES]. July 2, 1964 [July 27, 1963], No. 27351/64. Heading F1L. [Also in Division G3] A detonator comprises an inlet valve 2 and exhaust valve 3 which is connected to a working chamber, for instance the preliminary combustion chamber of a gas turbine. Air is sucked into an inlet 4 and channel 6, in the form of a laval nozzle, by high pressure gas supplied through laval nozzles 7. Detonation takes place in the combustion chamber 1 and exhaust takes place past the valve 3. The chamber 1 has a reaction chamber 1b which reflects the pressure wave thereby prevent back flow through the channel 6, this action being assisted by the gas flow from the nozzles 7. The exhaust valve 3 comprises a valve member 9 and the outer annular wall 13 has bent portions 14 which reflect gas forced back from the working chamber to form a barrier which prevents backflow of further gas. In a modification the inlet valve is formed by the gas preventing reverse flow.

Abstract: 1276143 Steam power plant; jet pump GENERAL ELECTRIC CO 29 May 1969 [14 June 1968] 27373/69 Headings F1E and F1Q In a power plant comprising a heat source with associated working fluid, some heated working fluid is passed to an engine which utilizes the heat and the resulting working fluid, cooled to between 400F. and 650F., is returned to the heat source by a jet pump. The jet pump consists of a nozzle and a body, the body comprising a converging inlet section, a mixer section of substantially constant cross-sectional area along its length and a diffuser section. The mixer section has a ratio of length to diameter of between 9-5:1 and 18:1. A recirculation pump supplies driving fluid to the jet pump nozzle so that the ratio of the weight flow-rate of driven fluid to driving fluid in the jet pump is between 1 and 2-5. More details of suitable dimensions for the jet pump are disclosed in the description. In an embodiment, a nuclear power plant of the boiling water type, an upright jet pump 32 pumps water into a feed water plenum 34 thereby forcing water through a reactor core 29 where it extracts heat and a portion of it is flashed into steam. The steam passes via a steam line 43 to a turbine 44 which drives an electric generator 47. Steam leaving the turbine is condensed in a condenser 45 and the condensate is returned by a pump 46 to a downcomer space 31 in the reactor. Driving fluid from the downcomer space is supplied to the jet pump nozzle 37 by a recirculation pump 35.

Abstract: 261,363. Soc. du Film en Couleurs Keller-Dorian. Nov. 16, 1925, [Convention date]. Colour photography. - A film embossed with microscopic linear refracting elements for use in conjunction with a lens filter comprising coloured zones in order to reproduce objects in natural colours, is characterized in that the width of each refracting element is from 10 to 40 per cent greater than the width of the image of the colour filter which it projects on the sensitive surface for a given aperture of the projecting lens. For embossing such films, a die is used whose surface is engraved with linear grooves numbering say 12 to 35 per millimetre, and of any desired shape in cross-section. The film is dried before embossing to such a degree, depending on the nature of the material of the film, and its temperature during the embossing process is so adjusted, that the material of the film will enter the grooves of the die and produce elements of the desired cur. vature under surface tension only, and without .making contact with the recessed surfaces of the die.

In Fig. 2 the powder 41 is enclosed by a moulding cylinder 42, within a graphite sleeve 60, inside a chamber which may be evacuated or filled with inert gas. Pressure is applied through a plunger 52, attached to plunger 48, which is sealed to a top plate 59 by metal bellows 53. High frequency current in a coil 63 induces heating in the sleeve 60. Water cooling is provided in channels 56, and a thermocouple 66 is fitted. Molybdenum, alumina and nickel-chromium alloy are used in construction.  The powder may be cold pressed before hot pressing, and a hot pressed article may be deformed by hot pressing in a larger diameter press followed by annealing.  Fig. 1 (not shown) illustrates a resistance heated press, and Fig. 3 (not shown) a press as in Fig. 2 but using graphite coated inserts on both sides of the powder, which reduce edge cracking in the pressed article by fitting the moulding cylinder perfectly during moulding, either being deformable or having higher thermal expansion than the moulding cylinder.
