Title: Improvements in or relating to the supercharging of internal combustion engines
IPC: F02B3/06
Filed: 1934-10-02
Abstract: 437,321. Four-stroke engines; valves. WICINSKI, A., 11, Ul. Kalecza, and BUJAK, J. Z., 11 a, Ul. Grunwaldzka, both in Lwow, Poland. Oct. 2, 1934, No. 28179. Addition to 433,821. [Classes 7 (ii) and 7 (vi)] The method of charging engines described in the parent Specification, according to which the admission of the charge is hindered during the first part of the inlet stroke so that a vacuum is produced in the cylinder which causes a more vigorous charging during the latter part of the stroke, is applied to engines working with a compressor, whether this is driven by the engine, or by an auxiliary motor, or by an exhaust-actuated turbine. The Figure shows an engine having a blower 5 which supplies the charge through a pipe 2 and valve 6, the pipe 2 being fitted with a valve 4 which is closed during the first part of the inlet stroke. The time of opening of the valve 4 may be regulated so that, whatever the speed of the engine, the time between such opening and the closure of the inlet valve 6 remains constant. In a modification, the valve 4 is omitted, and the charge is throttled during the first part of the inlet stroke, or the valve 6 is opened late. Specifications 428,739 and 433,821 are referred to.

Title: Improvements in or relating to switching devices
IPC: G06F5/01
Filed: 1954-09-30
Abstract: 759,662. Radiation sensitive devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 30, 1954 [Oct. 1, 1953], No. 28197/54. Class 40 (3). [Also in Groups XIX, XL (a) and XL (c)] Fig. 4 shows a photo-electric transfer tube switching device ; this comprises an envelope 50 having a glass rod 51 axially positioned therein coa,ted with a conductive material 51a such as copper. At one end of the tube is situated electrode 55 and at the other end electrodes 53, 54 which are spaced onequarter of a wave length apart. Radio frequency energy from oscillator 58 can be applied either between electrode 53 and 55 or 54 and 55 by the provision of switches 56, 57. Spaced at quarter of a wave length intervals along the tube are bands of lead sulphide 52x, 52y and the tube contains a gas or a mixture of gases, for example neon and sodium vapour, so proportioned that when the ultra high-frequency oscillations are applied from oscillator 58 bands of illumination are obtained at quarter of a wavelength intervals along the tube of a wavelength corresponding to that wavelength at which lead sulphide material is most sensitive. Thus discrete ionized layers are positioned along the tube and may be shifted by alternate employment of electrodes 53, and 54 in conjunction with electrodes 55. A resistivity change of approximately ten to one is obtained in the lead sulphide bands so that in the presence of illumination the sulphide acts as a closed switch while in the non-illuminated position it acts as an open switch. Thus if an input pulse is applied to terminal 1 with electrodes 53, 55 energized the lead sulphide bands 52x are in their state of low resistivity and an output is obtained at the " units " output terminal, alternatively when electrodes 54, 55 are energized lead sulphide band 52x operates as a high resistance and 52y as a low resistance so that the input at terminal 1 will be switched to the " tens " output terminal.

Title: Improvements in and relating to the treatment of textile materials with rubber
IPC: D06M15/693
Filed: 1936-10-22
Abstract: Rubber is deposited from aqueous dispersions on to textile fibres, e.g. of natural or artificial cellulose, silk or wool, by pretreating the fibres with an aqueous solution of a cationic soap compound which gives a positive ion comprising a long-chain aliphatic residue and subsequently immersing the fibres in the aqueous rubber dispersion. The cationic soap compounds comprise quaternary ammonium, phosphonium or sulphonium compounds containing an aliphatic residue of 8 or more carbon atoms such as cetyl pyridinium bromide, cetyl-trimethyl-ammonium chloride or bromide and cetyl-dimethyl-sulphonium methyl sulphate.  The treatment may be applied to loose fibres at any stage during manufacture into yarn, fabric or felt.  Felts may be made by treating carded webs.  Yarn may be treated in hank form.  The fibres may be wetted with a dilute sodium carbonate solution prior to immersion in the rubber latex. Oils, fats, waxes, and colouring matter may be added to the dispersions of rubber, balata, and guttapercha.  Wool may be mildly oxidized by treatment with hydrogen peroxide or chlorine as gas or in aqueous solution prior to treatment with the rubber dispersion.ALSO:Rubber is deposited from aqueous dispersions on to textile fibres, e.g. of natural or artificial cellulose, silk or wool, by pretreating the fibres with an aqueous solution of a cationic soap compound which gives a positive ion comprising a long chain aliphatic residue and subsequently immersing the fibres in the aqueous rubber dispersion.

IPC: H01G13/02
Filed: 1956-09-20
Abstract: 821,419. Electrical capacitors. TELEPHONE MANUFACTURING CO. Ltd. Sept. 5, 1957 [Sept. 20, 1956], No. 28766/56. Class 37. The capacitance of a length of metallized strip is measured and adjusted to a predetermined value by removal of part of the metallized surfaces before being wound to form the capacitor. The dielectric strip with metallizing on both sides 10, Fig. 1, passes from reel 11 through the pulley 12 and gripping pads 13 and 17, the distance between pads 13 and 17 being adjusted to give a predetermined length of dielectric strip. The nipping rolls 14 are adjusted to a position such that the capacitance of the dielectric strip between the rolls and the gripping pads 17 is slightly greater than that required and with the strip in position the burn-off voltage is fed to the rollers and the metallizing interrupted. Electrodes 15 and 16 are now brought into contact with each side of the dielectric strip and the capacitance of the strip measured by means of a bridge. The rolls 14 are then moved towards gripping pads 17 burning off the excess metallizing until the correct capacitance is obtained whereupon the guillotine 33 severs the dielectric strip at a predetermined distance from the rolls. The winding of the dielectric strip and the two wrappers 20 and 25 is affected by a pair of mandrel jaws 34 which are geared on a 2: 1 ratio with the rolls 14 so that the mandrel jaws are positioned in the middle of the measured strip. To wind the strips the mandrel jaws are rotated and the strips are released from the electrodes 15 and 16. Winding is continued until the dielectric strip is fully wound and a number of outer turns of the wrappers 20, 25 have been added whereupon the guillotine 36 cuts the wrappers, and gripping pads 37 and 38 grip the ends so that the assembly can be either heatsealed or contained in polystyrene wrappers. Specification 821,418 is referred to.

Abstract: 404,420. Electric ship propulsion plant. JOHNSON, E. M., 33, Poplar Grove, Brooklands, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Oct. 15, 1932, No. 28850. [Class 110 (iii).] In electric ship propulsion plant wherein a steam turbine drives an alternating current generator feeding an alternating current motor on the propeller shaft, the field windings are excitedwithdirect current from one or more generating sets each set comprising generators driven by a back-pressure steam turbine which exhausts either into the main steam turbine or into the condenser or to the atmosphere according to the load on the main turbine. The main turbine 1 is supplied with steam through an emergency valve 3 and governor valve 4 and exhausts into a condenser 5. A back-pressure turbine 6 drives a direct current generator and is under the control of a governor valve 8 from the pipe junction 12 in the main steam supply between the emergency valve 3 and the governor 4. The exhaust from the turbine 6 is controlled by a two-way valve 9 and can be led to a point in the supply to the turbine 1 or passed through the pipe 11 to the condenser. The two-way valve 9 is connected with the control gear of the turbine 1 or of the generator driven thereby so that when the load on the turbine or the speed thereof is above a predetermined value, the valve 9 is moved to open the pipe 10, when steam passes from the turbine 6 to the supply to the turbine 1. If the main turbine 1 is shut down by closure of the valve 3, the steam supply to the back-pressure turbine 6 is also cut off. If the supply to the turbine 6 is from a separate source, the emergency valve of the turbine 1 and the two-way valve 9 are interconnected so that on closure of the emergency valve the diverter valve 9 will be set to pass the turbine 6 exhaust to the condenser. The connections between the control valves may be by mechanical linkages or gearing or by electric or hydraulic transmission apparatus.
