Title: Improvements in "spring control for valves"
IPC: F02M1/00
Filed: 1926-04-07
Abstract: 264,043. Alston, J. S. E. April 7, 1926. Check hinged valves-A pivotallymounted valve has a torsional control spring associated therewith in such a manner that the closing tendency of the spring is lessened as the valve opens. As shown in Fig. 2, the suction-actuated air inlet valve 3 of a carburettor is returned to the closed position by a lever 8 carrying a roller 9 bearing against an arm 10 secured to the spindle 4 of the valve, the lever 8 being attached to a pivoted shaft 6 loaded by a coiled spring. As the valve opens, the roller 9 moves along the arm 10 nearer the spindle 4 thus offering a decreasing resistance.
Patent GB-967146-A (GB)
Title: A coded control for electro-responsive device
IPC: G07F13/02
Filed: 1963-03-08
Abstract: 967,146. Dispensing liquid fuel. A. O. SMITH CORPORATION March 8, 1963 [March 13, 1962], No. 9247/63. Heading A4T. [Also in Division G4] In a system in which in order to obtain access to a predetermined amount of petrol from a large tank maintained by a petrol distributer a proprietor of a petrol dispensing station has to depress a certain combination of keys on a key-board, the particular combination only being given to the proprietor when he has sufficient credit with the distributer, depression of an incorrect combination "locks" the equipment until it is reset by a representative from the distributer. As described when the tank is filled by the distributer a record card 17, Fig. 1, is inserted in a reader 37. The card is punched with a sequence of hole combinations known only to the distributer. When the proprietor wants a further issue of petrol he communicates with the distributer and if his credit is sufficient he is told the combination to key in order to release a further issue. If this combination is correctly keyed a further issue of petrol is released and the record card is advanced to the next column so that a different combination will have to be keyed for the next issue. If however an incorrect combination is keyed then the equipment 'locks' until it is reset by a representative of the distributer. The circuit for controlling the equipment is outlined and comprises principally two stepping switches 18, 19, a card reader 37 and a key-board having ten keys 32 and two keys 38, 39. In operation, with the record card in position, the proprietor depresses one of keys 38 and 39 and then three of keys 32. Each depression of a key 32 advances a contact 22 on switch 18 one position via a switch 52. If a 'correct' key combination is depressed closure of a "go" key 31 will allow current to pass via a contact 26 on switch 19, lead 29, and the displaced contact 22 of switch to a control solenoid 20 which releases an issue of petrol. If however the combination keyed does not match the combination punch in the record card depression of key 31 causes the energization of a relay 47 and the consequential advance of switch 19 by one step so that no circuit is, or can be, established for solenoid 20.
Patent GB-551525-A (GB)
Title: Separation of halide vapors
IPC: C01B7/00
Filed: 1941-07-23
Abstract: 551,525. Separation of halide vapours. PITTSBURGH PLATE GLASS CO. July 23. 1941, No. 9332. Convention date, March 15. [Classes 1 (ii) and 1 (iii)] Mixtures of metallic (including silicon) halide vapours other than iron chloride and titanium tetrachloride of which one is normally solid and the other normally liquid with a condensation point lower than that of the solid, are separated by condensing the major portion of the solid with enough of the liquid to wash the vapour and thus eliminate a substantial portion of condensed solid and thereafter further condensing the liquid halide. The mixture first condensed may be separated by evaporating the liquid halide sometimes in presence of a gaseous diluent. The vapour may be sprayed with a liquid halide to assist elimination. In the apparatus shown mixed vapours are introduced at 1 into condenser 2 and are cooled, e.g. to below 40‹C., the condensed mixture being collected in chamber 6, clogging being avoided by moving scrapers 5. Scrapers 8 in chamber 6 move the condensate to a zone where the liquid is vaporized and passes with the uncondensed vapour to a spraying condenser 11 where it is sprayed with a liquid halide and the condensate collected in chamber 12. Solid condensate emerges through outlet 17. The mixture may be produced by halogenating a metal bearing material. The metals concerned include iron-tin, iron-silicon, iron-zirconium, iron-vanadium, aluminiumtitanium, and aluminium-silicon, the halide being the chloride. Specifications 535,178 and 535,179 are referred to.

Title: Spacecraft Attitude Detector
Inventor: KELLY FRANKLIN GEORGE
IPC: G01S5/16
Filed: 1968-02-27
Abstract: 1,194,082. Altitude determinators. TRW Inc. 27 Feb., 1968, No. 9380/68. Heading H4D. Specification describes an altitude detector, comprising, mounted on the object whose altitude is to be determined, e.g. an octahedral sattelite 20, Fig. 1, a plurality of photo-detectors B1, B2, B4, B8, the positioning of the detectors being such, e.g. on alternate faces of the octahedron, that not all of the detectors will be irradiated by the reference light source 21 in any one orientation. Each detector, comprising a bank of solar cells, Fig. 7, is connected to a respective output detector and gating means 70a, 70b, 70c and 70d. When detector B1 is illuminated the output on line 28 causes means 70a to gate through the output of solar cell banks 23 as a voltage 8v. Illumination of the other detectors causes the voltage 8v to similarly appear at the outputs of their respective means 70. The output of means 70a is divided at 72 by 1/8 to give a voltage of 1v. Corresponding voltage dividers with factors of“  and ¢ give voltages of 2v. and 4v. when the detectors B2 and B4 respectively are illuminated. The thus detector indicative voltages of 1v., 2v., 4v. and 8v. are summed (but never all appearing simultaneously) in adder 75. The output of the adder 75 varies in discrete steps as shown in Fig. 8, depending on the altitude of the sattelite. The determined altitude may be transmitted to earth.

Title: Improvements in and relating to moisture-sensitive indicating or protecting devices for electrical apparatus
IPC: G01N19/10
Filed: 1932-04-01
Abstract: 380,383. Actuation of switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) April 1, 1932, No. 9441. Convention date, April 1, 1931. [Class 38 (v).] A moisture-sensitive switch comprises a contact arm 2 pivoted at 6 and carrying a contact bridge 4 which is urged into contact with fixed contacts 5 by a spring 3. A hempen cord 7 is connected to the arm 2 and to an adjusting screw 8. On the admission of moisture to the cord 7 it contracts and opens the switch. The switch is suitable for placing at the bottom of the container of an oil switch when the circuit controlled may operate an alarm to indicate the accumulation of water, or may open the circuit-breaker. Other moisture-sensitive elements may be used, such as a rod which expands on becoming moist, or a soluble salt.
Patent GB-177808-A (GB)
Title: Improvements in or relating to the measurement of high electrical resistances or ionization strengths
IPC: G01T1/185
Filed: 1922-04-01
Abstract: 177,808. Strauss, S., and Brandt, W. April 2, 1921, [Convention date]. Exposure meters.-In estimating photographic exposures with R÷ntgen-rays, radium emanations, sun's rays at high altitudes rich in ultra-violet light, rays from mercury vapour lamps or other rays or emanations by measuring the ionization strength of the rays &c., a condenser K is arranged in parallel with a closed discharge chamber exposed to the ionizing action of the rays &c. and is connected between the grid g of an electron tube R and a winding of a transformer S, the other winding of which is in the anode circuit. When the circuit is first completed, the transformer S induces a positive potential on the grid g, and the anode current and the grid potential consequently increase until, near the saturation point of the valve, the anode current cannot increase further, the potential induced by the transformer S on the grid is not maintained, the grid current reduces the grid potential, the anode current decreases to zero, and the resultant negative charge on the grid discharges through the discharge chamber until the original conditions are reached and the anode current is restarted. The number of discharges per unit time is taken as a measure of the ionization strength. The time of a complete cycle of charging and discharging is a sufficiently close approximation to the time of discharge. A telephone receiver T or a vacuum tube may be used to observe the successive charges or discharges. The discharge chamber has two electrodes close together in the form of plates, balls, or points, is covered by a suitable screen, and is exhausted or filled with rarefied helium so that the resistance between the electrodes depends on the degree of ionization produced by the rays tested.

Title: Improvements in and relating to lay figures or mannequins for making and fitting clothes and dresses
IPC: A41H5/01
Filed: 1948-04-05
Abstract: 645,162. Lay figures. CROSAZZO, V. April 5, 1948, No. 9468. Convention date, March 5, 1947. [Class 52 (v)] A lay figure comprises a lower element 1 and a centre element 4 pivoted on an axis 3. The centre element 4 has a projection 5 with a U-shaped extension 6 which receives a threaded nut 7 engaged by a threaded rod 8 so the block may be moved by rotation of the rod 8 causing the central element 4 to pivot about its axis 3. Similarly an upper element 11 is pivoted on an axis 10. The upper element 11 has shoulder pieces 16 each having a slotted extension 18. Pins 20 on a block 21 engage in the slots, the block 21 having a threaded hole engaged by a threaded rod 22 with a spherical enlargement 23 resting in a cup-shaped member 24. A conical nut 26 acting on the spherical enlargement enables the rod to take up and be held in an inclined position. When the wheel 27 is turned the block 21 will move causing the shoulders to be displaced through the same or different angles according to the inclination of the rod. To enable the figure to be reset in a predetermined position the elements are provided with graduations 28 which are read against pointers.
Patent GB-351084-A (GB)
Title: Improvements in or relating to the treatment of filaments or yarn composed wholly or partly of organic derivatives of cellulose
IPC: D06M13/224
Filed: 1930-03-25
Abstract: Filaments or yarns composed wholly or partly of cellulose acetate or other esters or ethers of cellulose are conditioned by means of a conditioning fluid containing as its effective ingredients a softening agent and a lubricant.  Suitable softening agents are polyhydric alcohols such as ethylene glycol, glycerine, and propylene glycol, although other softening or swelling agents such as toluene and xylene may be employed.  The lubricants used are vegetable oils such as castor or olive oil, animal oils such as neatsfoot oil, mineral oils such as lubricating oils obtained from petroleum, and fatty acids derived from animal and vegetable oils.  To the mixture of softening agents and lubricants, a solvent such as butyl or ethyl alcohol is generally added.  A suitable liquid consists of equal parts of diethylene glycol, castor oil, and butyl alcohol.  The conditioning liquid may be applied by immersing hanks therein, or it may be applied during the winding of the yarn from one package to another, for example, by means of pads, wicks, or wetted rollers, or the yarn may be passed through a bath of conditioning liquid, or such liquid may be dripped on to the yarn in transit, or it may be sprayed on to the package being wound; the conditioning liquid may be applied to the yarn as it leaves the cabinet in which it is being spun. Yarns so treated are flexible and are specially adapted for knitting since they permit of the making of fabric of closer construction than that obtainable with untreated yarns.  Specifications 308,733 and 333,949, [both in Class 2 (ii), Cellulose &c.], are referred to.
Patent GB-794389-A (GB)
Title: Improvements in or relating to removing an acidic component from a fluid stream
Inventor: BROWN KENNETH MICHAEL
IPC: B01D47/02
Filed: 1956-03-27
Abstract: <PICT:0794389/III/1> Acidic components are removed from a gaseous or liquid stream by countercurrently contacting said stream with an aqueous alkali metal hydroxide in an absorption zone, and drying the thus-formed wet stream with a more concentrated (e.g. a solid) alkali metal hydroxide, the alkali metal hydroxide in the absorption zone being obtained by adding water to concentrated aqueous alkali metal hydroxide obtained from the drying zone.  Fluid streams referred to are hydrogen containing hydrogen sulphide or carbon dioxide, gasoline containing mercaptans and hydrocarbons containing hydrogen sulphide. The concentration of the hydroxide in the absorption zone should not exceed 25 per cent, to avoid crystallization of sodium sulphide, carbonate or other compound formed.  If a solid is used in the drying stage it is preferred to have two zones in parallel to permit continuous operation when recharging.  One illustrated embodiment (Fig. 1, not shown) involves the use, in connection with removal of hydrogen sulphide from hydrogen, of solid sodium hydroxide in the drying zone and recirculation of dilute caustic soda in the absorption zone, said zones being superposed in a single column. A second embodiment (see Fig. 2) involves the use, in connection with removal of hydrogen sulphide from a gaseous stream, of a concentrated aqueous solution of caustic soda in two drying zones 25 and 26 and a more dilute caustic soda in an absorption zone 24, wherein in each of said zones liquid is recirculated from a lower to an upper part of the zone.  More than one absorption zone or more than two drying zones may, if desired, be used; in place of the perforated plates illustrated or bubble trays &c., packing such as Raschig rings may be used.

Title: Improvements in or relating to electric circuit interrupters of the single bushing type
IPC: H02H3/28
Filed: 1959-03-19
Abstract: 859,866. Protective cut-out arrangements; gas-blast switches; automatic circuit-breakers. WESTINGHOUSE ELECTRIC CORPORATION. March 19, 1959 [March 31, 1958], No. 9534/59. Class 38 (5). In an overlapping differential protective arrangement, the current transformers 30, 31 associated with a bus-bar section circuitbreaker C are arranged on either side of an earthed supporting-plate 5 connected to a conducting shield which is so arranged that internal fault currents must flow between the current transformers to earth and cause operation of the protective systems on both sides of the circuitbreaker. The circuit-breaker C is that of Specification 848,184 and is provided with a closing coil 51 and a latch 58 which may be released by either of two solenoids 112, 116 under the control of relays 107, 108. Assuming that power flows from feeders L1, L2 and that an internal fault in the circuit-breaker C occurs, e.g. as indicated at P, the fault current flows through current transformers 119, 120 but not through transformer 31 so that relay 108 is operated to trip circuit-breakers A, B and C. The fault current flows to earth through conducting members 44, 37, 36, 28 and 5, i.e. through current transformer 30, so that relay 107 is operated to open the circuit-breakers X, Y. If on the other hand the power had been flowing from feeders L3, L4, the fault current flows through the transformer 31 and produces operation of the relay 108, but the fault current through the stud forming the primary of the transformers 30, 31, is, insofar as the transformer 30 is concerned, counterbalanced by the fault current flowing to earth through the conducting shield and the plate 5. Hence the secondary current of transformer 30 is not equal to that of the transformers 117, 118 and relay 107 is operated. A conducting cover 126 encloses the transformer 31 to prevent incorrect operation due to external faults such as that indicated at N. Specification 736,090 also is referred to.

Abstract: 500,770. Food for animals; sugar preparations. VITAMOL, Inc. March 29, 1938, No. 9568. Convention date, Sept. 30, 1937.. [Class 5 (ii)] [Also in Group VI] A vitamin composition for addition to food for cattle and poultry is made by emulsifying a vitamin A and D concentrate in oil with sugar cane molasses under conditions that avoid churning air into the composition. The emulsification may be effected in a turbine mixer followed by a colloid mill. The particles of the concentrate become coated with sugar solution, and the vitamin A is thereby protected from oxidation.
Patent GB-269195-A (GB)
Title: Improvements in the treatment of yarn packages with liquids, and in products obtained thereby
IPC: D06P1/00
Filed: 1927-04-08
Abstract: 269,195. British Celanese, Ltd., (Assignees of Whitehead, W.). April 12, 1926, [Convention date]. Yarns, specially treated, fabrics with.-Yarns made of or containing cellulose acetate or other cellulose esters or ethers showing in their length differences in shade or colour, for the production of effects in woven or knitted fabrics, are obtained by immersing in organic liquids containing dyestuffs or bleaching or colour-stripping agents cops, bobbins, spools or other wound yarn packages, the latter being removed from the bath before a uniform colour change throughout the yarn package has taken place. In the case of cops or spools wound on perforated bobbins or tubes, the outer layers of the package may be protected by another winding of yarn or by other wrappings, the inner layers of yarn being then dyed a deeper colour than the outer layers. To obtain multiple colour effects, there may be dissolved in the bath a number of dystuffs of different penetrative powers, for instance, a benzene solution of aminoazobenzene and methylaminoanthraquinone, the former being more penetrative when used for the treatment of a spool of cellulose acteate yarn. A similar multi-coloured effect is obtained by employing a succession of treatments with different dyestuffs, the time of immersion being suitablly adjusted. Instead of using dyebaths, there may be employed cops &c, of dyed yarns in conjunction with baths of bleaching or stripping-agents, and in such cases the process of stripping described in Specification 260,289, [Class 15 (i), Dyeing &c., Apparatus for], may be employed. The ultimate effect produced on the woven or knitted fabric depends on the character of the windings of the package, and on the nature of the fabric. Thus, with a bottle type of winding and a knitted fabric, a speckled effect is obtained; with a parallel-wind bobbin and a weft-faced satin, the fabric will show bands of altarnately light and dark shades; with cops dyed on their outer layers to a shade deeper than that of the inner layers, and the resulting yarn employed both as warp and weft in a taffetas-weave fabric, the effect consists of a series of criss-cross markings. The packages may be protected at selected places by means of mechanical devices, or they may be only partly immersed in the treating liquids. The Specification as open to inspection under Sect. 91 (3) (a) is not restricted to the use of organic liquids for the preparation of the baths, and comprises alro the treatment of yarns of all textile materials, including cellulose and regenerated cellulose, in addition to those containing cellulose esters or ethers. Multiple colour effects are also obtained by employing the dyestuffs in different forms, for instance, an aqueous solution of rosaniline hydrochloride may have mixed with it a dispersion of methlyaminoanthraquinone, the rosaniline hydrochloride showing greater penetrative power. This subject-matter does not appear in the Specification as accepted.
