Title: Improvements in or relating to elastic yarns and the manufacture thereof
Inventor: HALL RICHARD
IPC: D02G3/32
Filed: 1965-01-14
Abstract: A composite elastic yarn comprises at least one bulked thermoplastic yarn and an elastic filament-e.g. of rubber or spandex.  The composite yarn is produced by feeding to a pair of capstan rolls and a ring spinning spindle the elastic filament from a package driven by a roller geared to the capstan rolls so that the filament is stretched by 50-400%, and the thermoplastic yarn under sufficient tension to remove its added bulk.  The thermoplastic yarn may be a staple fibre or multi-filament yarn of a polyester, nylon, cellulose acetate, a polyolefin or an acrylonitrile polymer or copolymer, and may be bulked by means of a fluid jet, or by being crimped by false-twisting, stuffer crimping, or gear crimping, or in the case of a blend of shrinkable and non-shrinkable fibres, by shrinking the yarn.

Title: Magneto hydrodynamic generator
IPC: H02K44/08
Filed: 1963-01-15
Abstract: 1,035,522. Generators operating by electromagnetic interaction with fluids. BROWN, BOVERI & CO. Ltd. Jan. 15, 1963 [Jan. 17, 1962], No. 1763/63. Heading H2A. Changes in the gas pressure gradient due to changes in loading of a magnetohydrodynamic generator are obviated by making the ratio of the longitudinal distance between electrode pairs, of one load circuit, to the transverse distance between electrodes equal to the ratio of the Hall voltage to the resistive voltage in the duct. The Hall voltage is directed longitudinally of the duct and the resistive voltage is the transverse voltage generated between a single pair of electrodes. As described, a number of separate circuits may be used in the generator each circuit necessarily having this same constructional feature. It is also disclosed that if the duct tapers the longitudinal distance between electrodes will advantageously change along the duct in order to keep the ratio constant at all positions in the duct. Use of this construction is said to greatly facilitate control of the generator since pressure drop along the duct is independent of load changes.

Title: Improvements in hydraulic control valve apparatus
IPC: F16K31/122
Filed: 1957-01-18
Abstract: 818,533. Valves. GRATZMULLER, J. L. Jan. 18, 1957 [Jan. 18, 1956], No. 1905/57. Class 135. Upon depressing a knob 11 a plunger 39 is moved to both close an exhaust port 42 communicating with a tank 38 and unseat a ball 9 against a spring 10, whereupon liquid from an accumulator 4 passes through a conduit 7, sharp-edged orifice 33 and duct 13 to act upon the top of a piston 1 loaded by a spring 14. Immediately or after some lost-motion the piston 1 causes an extension 32 of the pistonrod 15, to unseat a loose ball 31, whereby liquid from the accumulator 4 flows to a utilization circuit 3 via conduit 6, another sharpedged orifice 51, bores 29, 28, ports 43, a bore 19 and outlet 27; the orifices 33, 51 ensure that the amount of liquid supplied to the piston 1 and circuit 3 is proportional. As the piston 1 continues its stroke its shoulder 15<SP>1</SP> abuts a valve closure 21, which houses the ball 31 and orifice 51, and forces it off a seat 23 so enabling liquid from conduit 6 to flow directly to the outlet 27; liquid may also continue to flow to the latter through the path which includes the orifice 51. In a modification, the circuit 3 is provided with a path to the tank 38 through a valve formed between two parts of the piston rod, the valve being closed before the ball 31 is unseated during the downward movement of the piston. A second utilization circuit is fed directly from the upper end of the duct 13 whilst the sharp-edged orifice 33 is disposed between the lower end of the duct 13 and the cylinder of piston 1.

Title: Improved tensioning means applicable more especially to tennis nets
IPC: A63B61/02
Filed: 1936-01-23
Abstract: 466,148. Straining tennis nets &c. STEVENS, B. Jan. 23, 1936, No. 2129. [Class 45] Relates to means for straining the wire cords of tennis nets or for stressing rods. The wire D is clamped between discs c<1> secured by set screws c<6> and gapped at c<3> to pass over rectangular bosses c<4> on the inner side of two outer discs, c, one of which is shown in Fig. 4. The discs are kept in position on a'spindle F by the side walls b<2> of a bracket B. The spindle F is carried by links E, pivoted at their lower ends to a boss b<4> on the lower surface of the bracket. In order to tighten the wire, a lever G having projections g, g<1>, is applied as shown in full lines in Fig. 5 and turned clockwise to rotate the discs. The projection g rests on the periphery of the discs and the projection g<1> engages one of a series of teeth C<7> in a recess in the outer wall of the disc c. On the release of the lever, the tension of the cord pulls the roller to the left and causes it to turn about the lower pivot of the links E and to be forced with considerable pressure against the base plate b of the bracket, thus holding it from turning. To slacken the cord, the lever is applied as shown in broken lines and the discs are levered to the right to a position in which they are free to rotate. In a modification, Fig. 10, a rod Q to be stressed is hooked directly to the discs, The supporting surface is on a plate J pivoted at j and supported at the other end by a toggle device K. The lower member k of the toggle is rigid with a handle M, so that the toggle can be broken into the position shown in broken lines when the tension is to be released. In another form, the rod is pivoted to a lever integral with the discs. The two latter forms may be used for giving compression to a rod.

Title: Improvements in or relating to beam-type electron tubes
IPC: H01J29/82
Filed: 1962-01-23
Abstract: 974,902. Cathode-ray tubes. LITTON INDUSTRIES Inc. Jan. 23, 1962 [Feb. 24, 1961], No. 2358/62. Heading H1D. An electron gun is located against radial movement by at least three peripherally-spaced inward protrusions of glass from the neck portion of the tube envelope, at least one of the protrusions being formed at such a peripheral point and of such depth as to move the gun structure for correction of initial misalignment of the beam from a preferred point on the tube screen. As shown, the gun electrodes of a cathode-ray display tube are secured to side rods 66, Fig. 6, of " Pyrex " (Registered Trade Mark), and initially the gun is mounted within the tube solely by its input leads. After evacuation of the tube and application of operating potentials to the gun electrodes, a first protrusion, to engage titanium end flange 60, is formed by use of a torch having a central plunger surrounded by a ring of gas jets, the plunger being used to move the gun into correct axial alignment with polar co-ordinate markings on the tube screen. Afterwards the glass is softened at two additional points to engage flange 60. Three protrusions are similarly formed to engage end flange 62, a further alignment adjustment being made, if necessary. Additional protrusions 64, 65 may engage side rods 66 if the flanges 60, 62 and tube neck have substantially different coefficients of expansion. After formation of the protrusions internal stresses may be relieved by heating the tube neck. To avoid electric field disturbances caused by the side rods, these may be omitted, the electrodes being mounted on a jig within the tube neck and secured in position by protrusions 94, 98, 102, Fig. 8. After removal of the jig, and tube exhaustion, the gun alignment may be adjusted during formation of protrusions 106. The protrusions may be made through the use of an intermediate element of glass having a higher melting point than the adjacent tube neck.
