Title: Improvements relating to thyratrons
Inventor: MCCORMICK NORMAN ROBERT
IPC: H01J17/56
Filed: 1956-08-16
Abstract: 860,867. Thermionic valves. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 16, 1957 [Aug. 16, 1956], No. 25098/56. Class 39(1). In a gas-filled discharge device such as a hydrogen thyratron the control electrode is formed as a plurality of control elements G1. . . . GN located at progressive distances between cathode and anode, some of which are individually connected through a resistance to a voltage source, either as shown, or as successive tappings on a single resistance; the elements form a first group acting as priming grids, and a second group acting as firing grids. Fig. 3 shows an embodiment in which the control electrode has three component parts disposed between cathode 2 and anode 1. Part 8 corresponds to Gl, the cylinder 5, washers 3 and 4 and disc 7 together correspond to G2, and the disc 6 to G3; disc 7 ensures that the arc, in extending to G3, cannot extend to the underside but only to the top, hence entering the influence of the anode field. Fig. 4 (not shown) is a modification in which the grid aperture is in the form of radial or annular slots. To reduce the deionisation time, negative bias may be applied to any grid or group of grids.

Title: Process for the manufacture of wrapped yarn
IPC: D02G3/46
Filed: 1975-06-12
Abstract: 1515923 Wrapped yarn HOECHST AG 12 June 1975 [12 June 1974] 25249/75 Heading D1F and D1W A drawn sliver of staple fibres 1 having a degree of longitudinal orientation of at least 85 percent is wrapped by at least one filamentary yarn 9 having a denier of less than 50 dtex, wherein the or each filamentary yarn 9 is withdrawn from a bobbin 8 having a hollow shaft 7 through which the sliver 1 is passed, and is wrapped, under a tension of not more than 5 grammes, around the sliver 1. A balloon-limiting device 10, which rotates with the bobbin 8, is provided. Ballooning can be limited by using a bobbin in which the yarn is wound from the inside by means of centrifugal forces. The wrapped yarn is spooled around a winding bobbin 6. During the wrapping operation the wrapped yarn preferably has a tension in the range of from ten to one hundred times the filament tension. A mixture of staple fibres having different shrinkage factors may be used in the sliver I, and the shrinkage is initiated after the wrapping operation, but before spooling the wrapped yarn. The wrapped yarn may be submitted to a fixing process before being spooled and it may also pass through a paraffinizer device. The strength of the filamentary yarn at a specific load is at least 10g at an elongation of 4% and the elongation at break is at least identical with the lowest occurring elongation of the staple fibre component. Also the filamentary yarn has a shrinkage range within 10% of the shrinkage range of staple fibre component having the highest shrinkage values. The bobbin has a maximum weight of 250g and rotates at a rate of at least 20000 revolutions per minute. The sliver may be wrapped by two filamentary yarns arranged in opposite directions. In the case of webs or coloured yarns, if the winding filamentary yarn is a non-delusted monofilament yarn being as transparent as possible a special colouring operation of the winding filament is avoided. The filamentary yarn is composed of fibreforming high molecular weight polymers, preferably, polyester or polyamide. The staple fibres may be composed of natural or synthetic fibres or mixtures thereof. Suitable synthetic fibres are fibres of polyester, preferably polyethylene terephthalate, polyacrylonitrile and copolymers thereof, polyamides such as Polyamide 6 and Polyamide 66, polyolefins such as polypropylene and polyethylene, viscose staple fibre etc.

Abstract: 597,682. Flying tops and projectors therefor. LEFUSTEC, F. A. Sept. 28, 1945, Nos. 25294 and 25295. Convention dates, Feb. 19, and May 14. [Classes 132 (ii) and 132 (iii)] A multipart toy comprises a flying top, Fig. 10, formed of a propeller 1 having a plurality of balanced blades carried at the end of a shaft 3 the other end 4 of which is weighted, means for imparting motion to said top and a top receiving member, Fig. 22, comprising a plate and handle therefor. The propeller may be of any shape (Figs. 1, 6), and the blades may be surrounded by a ring 2. The blades are twisted slightly out of the horizontal. The shaft 3 may be integral with the propeller or may be affixed or secured thereto by any known means, and it may be fluted or channelled to form a pinion to facilitate the driving of the top. The spinning device in Fig. 15 comprises a handle 5 carrying a transverse axle 6 provided with a crank 7. A toothed wheel 8 is provided on said axle, the teeth of which engage the flutings 13 on the shaft 3 of the top which is supported on an extension 10 of the handle, the end of the extension being screw-threaded to receive the foot 12 of the top. On turning the handle rapidly the top is quickly unscrewed, a lifting force being created enabling it to fly off the extension. It falls to the ground after a time and continues to spin, unless caught on the top receiving member Fig. 22. This member is formed from a plate or blade 30 extended at one of its ends in the shape of a tongue 31 interposed between two half-handles 32. Hollows 33 and 34 are provided at the other end of the plate. A small flange 35 may be provided as a safety measure. The plate is used to catch the top as it falls, and then the player guides by tilting the plate on the still-spinning top into one of the hollows. If these hollows are provided with numbers, the numbers carried by these hollows dnto which he guides the top count as his score. The plate may be decorated in any suitable manner, for example, it may carry the silhouette of an aeroplane. Devices are described for the simultaneous spinning and ejection into the air of a number of tops and also several forms of a combined spinning device and top-receiving member.

Abstract: 687,881. Direct-acting engines; cooling exhaust and cylinders; spray-carburetters; valves. BERGMAN, G. A. Oct. 23, 1950 [April 29, 1950], No. 25789/50. Classes 7 (ii), 7 (iii), 7 (iv) and 7 (vi). In an engine particularly for the actuation of boring, chiselling, or breaking tools, rivet hammers, or the like, the fuel supply nozzle 64 is situated in the induction passage 42 at a point between two suction-actuated leaf spring valves 44, 46. In a two-stroke crankcase compression engine having a compressor piston 124, Fig. 3 connected to a crankshaft 86 and an impact plunger 127 actuating the tool, the air is drawn by suction through a rotatable choke valve 24, annular channel 16, filters 30, 32 and valve 44 and, after carburetting at the nozzle 64, the mixture is sucked through the valve 46 into the crank-chamber 56, the flow being controlled by a throttle valve 70. The valves 44, 46 each comprise a leaf spring 48 backed by a rigid stop 50, the valve 44 being attached to a member 38 removable as a unit with the choke 24 and filter body 14, and the valve 46 being carried by a removable plate, 54. The intake passage 42 is formed in a continuation of the crank-chamber wall 10, which continuation also forms a fuel tank 58 feeding the nozzle 64 directly through a pipe 60 e.g. of copper moulded into the wall, a fuel filter 76 being carried by a nut-shaped member 80. A three-way cock may be included in the pipe 60 to enable the nozzle 64 to be fed from the top of the fuel tank when the device is operating upside down. The fuel nozzle 64, Fig. 4, is held in position by a spring 66 and. sealed by resilient washers 69, a needle 68 being actuated by a thumb-screw 71 to vary the nozzle orifices. The mixture is transferred from the crank-chamber 56 through a port 130 in the piston co-operating with a transfer passage 132, and the exhaust pipe 136 is mounted inside a casing 138 through which cooling air is blown by a fan 88 on the crankshaft. The fly-wheel 114 also forms a cooling fan and carries a ring of permanent magnets 108 forming part of the magneto mechanism 116 which is carried by a removable crankchamber cover 110.
