Patent GB-1051814-A (GB)
IPC: D06L4/636
Filed: 1965-05-28
Abstract: 1,051,814. Brightening polyester fibres. J. R. GEIGY A.G. May 28, 1965 [May 29, 1964], No. 22781/65. Heading D1P. Fibres made from terephthalic acid polyesters are optically brightened by impregnating them with an aqueous medium comprising dispersed therein 0.5-6 grams per litre of the compound of the formula the dispersed particles of the compound having a particle size of less than 10Á, squeezing out the impregnated fibres and then heating them at a temperature of 180‹-220‹C. The fine degree of distribution of the brightener may be obtained by milling with sand in the presence of water and a dispersing agent, e.g. a condensation product of naphthalene sulphonic acids and formaldehyde, which may be present in an amount of 1/30th to 1/10th of the weight of the brightener used. The dispersion may also contain thickening agents, e.g. fatty alcohol polyglycol ethers such as stearyl alcohol polyglycol ethers having 8-10 ethyleneoxy groups, or protective colloids, e.g. high polymeric polyacrylates and polyacrylamides, and thickeners, e.g. alginates, carboxy methyl cellulose and methyl cellulose. After the squeexing out the fibres may be dried prior to the heat treatment. Fabrics comprising terephthalic acid polyester fibres and cotton fibres may be brightened by the use of an aqueous dispersion comprising the brightener in admixture with a brightening agent for the cotton, e.g. or may subsequently be treated with the brightener for cotton. The mixed fibre fabrics may be bleached with sodium chlorite or hydrogen peroxide prior to treatment with the brightening agents, or the brightening agent for cotton may be applied subsequently together with a hydrogen peroxide solution containing sodium silicate and sodium hydroxide.

Title: Method of joining cylindrical sections of a pile driving mandrel to withstand impactforces
IPC: E02D7/30
Filed: 1964-06-02
Abstract: 1,002,741. Pile driving mandrels. F. RUSCHE. June 2, 1964 [Nov. 15, 1963], No. 22786/64. Heading E1H. A method of detachably joining together two cylindrical sections of a pile driving mandrel comprises bringing their end faces together or into abutting relationship with a coupling element and detachably interlocking axially extensive surfaces of the respective sections, said interlocking being made at positions axially removed from said abutting end surfaces and radially inwardly of the resulting outside surface of the joined sections. As shown, two sections 10, 12 of a removable mandrel are joined by a coupling 13. The coupling has a shoulder 27 against which end surfaces of the sections 10, 12 abut to receive compressive forces. Studs 56 are received into holes 58 to prevent any relative rotational movement between the sections. The sections are also provided with grooves 22 which form with grooves 20 on the coupling a chamber in which balls 18 are inserted through holes 26. These balls are unaffected by compressive forces but are used to transmit tensile forces from the upper section to the lower section when it is required to remove the mandrel. The coupling is hollow to enable a conduit 50 to pass therethrough and connect tubular sections 48, 49. The conduit 50 thus allows fluid to pass into lower section 12 to express plugs 32 into engagement with shell pile casing 12a. Specification 891,080 is referred to.

Title: Improvements in and relating to the control or measurement of speed and frequency inelectric systems and apparatus
IPC: G01P3/44
Filed: 1933-08-16
Abstract: 425,758. Automatic regulation. SHUTTLEWORTH, N., Admiralty Research Laboratory, Teddington, Middlesex, and DRYSDALE, C. V., Admiralty, London. Aug. 16, 1933, No. 22879. [Class 38 (iv)] [See also Groups XXXVI and XXXVII] The frequency of an alternating current or the speed of a machine producing the current is controlled by means of a tuned reference circuit having both a fixed and a relatively movable coupling with the circuit to which the supply or generated frequency is applied, the movable part of the coupling having such limited movement as to cause, when displaced from the neutral position, negligible variation in the frequency of the reference circuit. In one arrangement, Figs. 1 and 2, the circuit in which the frequency is to be controlled includes windings B, E on a magnetic core, and the tuned circuit includes an inductance L, variable condenser C, a winding D on the core, and a winding A mounted to rotate in air gaps in the core against the action of a spring J. Any variation in the frequency of the supply from that of the tuned circuit causes the coil A to move in one or the other direction to bring a contact arm G into engagement with one or other of the fixed contacts H, K. The latter may be connected to the respective terminals of two field windings of a series motor which is caused to rotate in one or the other direction in order to apply the necessary correction in the supply frequency. The shaft of the motor may, for example, adjust a field rheostat, as shown. in Fig. 2, or rotate a brush shifting device, or in cases where the circuit to be controlled, is that of a valve oscillator, it may adjust a variable condenser. For higher frequencies the magnetic core may be dispensed with and for still higher frequencies an electrostatic form of control may be used, as shown in Fig. 7. In this arrangement the tuned reference circuit CF is coupled to a coil AB in the circuit of which the frequency is to be controlled, and the voltages across AB and CF are applied to an inner and outer set of metal plates arranged in quadrature, the inner set of plates being rotatably mounted and carrying a contact arm.

Title: Torpedo steering system
IPC: F42B19/01
Filed: 1960-07-05
Abstract: 920,845. Torpedoes. CLEVITE CORPORATION. July 5, 1960 [July 16, 1959], No. 23453/60. Class 9 (2). A torpedo has a tubular body and one or more control surfaces movable relatively to the body and spaced therefrom, each control surface extending circumferentially of a circle centred on the axis of the body and of diameter not greater than that of the body. In Fig. 1, a shroud ring 12 is supported from the torpedo body 10 by struts and has adjustable trailing edge surfaces 18, 20, 22, and 24. Each surface is deflectable inwards from its streamlined position by a one-way acting plunger controlled by hydraulic pressure, see Fig. 5 (not shown), transmitted through a bore in the adjacent strut from a master unit 58 shown in Fig. 6. This comprises a housing 60 with end walls 62, 64, containing a solenoid winding 70 and a suitable insulating layer 71. A sleeve 74 having a part conical end 77 is disposed in a bore within layer 71, end 77 mating with one end of a plunger 80. A piston 90 within sleeve 74 is urged towards plunger 80 by a spring 96, and has a T-shaped internal conduit system 93 communicating with a piping system 100 leading to the control surface operating plunger (not shown). When the device is de-energized, the spring 96 moves the piston 90 and plunger 80 until the latter abuts wall 62. When the solenoid is energized, plunger 80 is attracted magnetically into the solenoid winding, and fluid flows through conduit system 93 to the piping 100. When the conduit system enters sleeve 74, fluid can no longer flow through it, but continues to flow through piping 100 as piston 90 is advanced by plunger 80. The control surface is thus displaced until further displacement is prevented by a pre-set stop, Fig. 5 (not shown). When the solenoid is deenergized, the surface returns to its streamline position. In a modification, the control surfaces 18, 20, 22, 24 are omitted, and the shroud ring is universally tiltable, as in Fig. 8, where a part-spherical bearing member 128 supports a ring 126 on which the shroud ring is supported by struts 124. Each of four balls 132 (an opposed pair are shown) is connected by a rod 131 to a plunger 104 operable by the pressure in the piping of its associated control unit 58, Fig. 6. Springs 146 urge the ring 126 away from the torpedo body. Operation of any one unit tilts the ring to produce a control effect.

Title: Apparatus for use in measuring the dryness fraction of steam
Filed: 1937-08-28
Abstract: 497,452. Determining the moisture content of steam. BEALE, E. S. L., and DOBBIE, McINNES, Ltd. Aug. 28, 1937, No. 23598. [Class 97 (iii)] The rate of flow of the steam under test through a conduit is adjusted so that for any pressure the product W x L has a con. stant predetermined value (W being the flow in 1b. per min. and L the latent heat of the steam) and the moisture content of the steam is then determined directly from the heat input necessary to render it just dry, heat losses being approximately compensated for. As shown, a test flow of steam passes from the main pipe 2 over the electric heater 5, which is connected through a wattmeter 13 and then passes through the valve 7 and orifice 16 to a condenser 21 at atmospheric pressure. In use, the valve 7 is adjusted until a pressure gauge 20, connected to the space above the orifice 16, gives an indication corresponding to the pressure in the main pipe 2 on a modified scale. A scale 20a is provided to enable zero adjustment of the gauge 20 in accordance with the barometric pressure. Thermocouples 8, 9, and a millivoltmeter 10 enable the point at which the steam first becomes dry to be determined. The wattmeter 13 is provided with a scale 136 for zero adjustments in accordance with the pressure in the main 2. Specification 444,807 is referred to.

Title: Process for modifying aluminium alloys containing silicon
IPC: C22C21/02
Filed: 1931-08-24
Abstract: Aluminium silicon alloys containing 5-30 per cent of silicon are improved or modified by treating the molten alloy with mixtures comprising fluorides that per se are incapable of producing a modifying effect and alkali carbonates.  Such stable fluorides comprise fluorides of alkaline-earth metals, aluminium, magnesium, heavy metals such as manganese, zinc, and double fluorides of alkali metals.  The melting-point of the mixtures may be reduced by additions of salts or known fluxes such as alkali chlorides. Constituents of the alloys other than silicon, for example iron, copper, manganese, cobalt, &c., also become highly dispersed by the treatment.  The process may be used as a pretreatment to known modifying processes for example, after adding the reaction mixture metallic sodium may be added to the melt through the flux.  The treated alloys may be further subjected to mechanical or heat treatment.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the age-hardening of the treated alloys by annealing at temperatures above 400 DEG  C., quenching and ageing at ordinary or elevated temperatures, and the use of borates as fluxes for lowering the melting temperatures of the reaction mixture.  This subject-matter does not appear in the Specification as accepted.
