Filed: 1926-11-12
Abstract: 277,526. Whatmough, W. A., and. Fisher, W. L. Nov. 12, 1926. Thermostats.-The temperature of the air supplied to a carburettor is maintained substantially constant by controlling supplies of heated and cold air by valves actuated by a temperature-sensitive device located in the path of and completely surrounded by the whole of the air mixturel or of the fuel and air mixture. A conduit 1 is connected at the end 2 to a hot air supply, e.g. a casing around the exhaust pipe, whilst the end 4 is in direct communication with the atmosphere and admits cold air. The hot and cold air are controlled by valves 13, 16 connected through link work 14, 12, 11, 10, 9 with the temperaturesensitive device consisting of a metal bellows 7 containing a volatile liquid and mounted in a chamber 5 so as to be completely surrounded by the stream of mixed hot and cold air. The bellows may be replaced by a bi-metallic strip. The temperature may be adjusted by a screw, spring or other device which may be interconnected with the throttle.-actuating means.

Title: Improvements in or relating to metal alloys and articles
IPC: C22C1/04
Filed: 1957-09-11
Abstract: 872,051. Aluminium alloys; granulating; powder metallurgy. KAYSER ALUMINUM CHEMICAL CORPORATION. Sept. 11, 1957 [Dec. 14, 1956], No. 28691/57. Classes 82(1) and 82(2) Aluminium alloys, containing alloying additions in amounts reaching those possible in the production of sound workable cast bodies, are produced by comminuting a homogeneous melt of the alloys, solidifying and cooling the particles at a rate sufficiently rapid to prevent or substantially prevent formation of coarse crystals of intermediate phases, and consolidating the particles by working. The melt may be comminuted in the apparatus shown in which a melt from a container 1 passes through a tubular passage 3 and is blown to form particles by jets of gas from converging nozzles 6, the particles being collected in a cooling liquid in tank 8. The particles may be consolidated by cold compacting followed by hot compacting and further working such as extrusion. For example a charge may be pressed at 25,000 p.s.i. in a die lubricated with stearic acid and aluminium flake pigment in carbon tetrachloride. The green billet is then lightly compressed while being heated to the extrusion temperature of above 500‹F., e.g. 650-1100 ‹F. and the pressure is then increased to 80,000 p.s.i. which is maintained for five minutes. Finally the billet is extruded. The pressure during hot pressing may be increased to 100,000 p.s.i. Among the alloys which may be treated in accordance with the invention are the following, 0.5-4% of Ti, balance Al and impurities; 0.1-2.5% of V, balance A1 and impurities; 4.5-13.0% of Cu, 1.5-5.0% of Mn, 0.2-2.0% of Zr, 0.1-1.0% of V, balance A1 and impurities; 7.5% of Fe, 2.0% of Cr, Ti or Zr, balance A1 and impurities; 3.5-5.0% of Mn, one or more of 2.0-7.5% of Fe, 1.0% of Cr, 0.5-2.0% of Ti, 1.0-2.0% of Zr and 0.5-1.0% of V, balance A1 and impurities; 3.0-10.0% of Mu, balance Al; 1.0-6.0% of Zr, balance A1 and imprities; 3.0-12.0% of Fe, balance Al and impurities; 2.5-5.0% of Mo, balance Al and impurities; 1.0-6.0% of Cr, balance A1 and impurities.

Title: Improvements relating to lift control systems
Inventor: GRAY COLIN HAMILTON
IPC: B66B1/50
Filed: 1969-06-06
Abstract: 1298556 Lift control systems UNITED LIFT & ESCALATOR CO Ltd 3 June 1970 [6 June 1969] 28793/69 Heading B8L A lift control system comprises a series of magnetically operable reed switch means, one reed switch means associated with each floor, magnetic means carried by a lift car and located so as to move past and operate the reed switch means in turn during travel of the car, and destination control means associated with each floor, the arrangement being such that operation of a destination control means controls the lift to move towards the appropriate floor and that when the car approaches the required floor the magnetic means operates the reed switch means associated with that floor to cause the car to stop. When the lift is standing at the first floor and is called to the fourth floor, destination control switch 4R is closed, the reed switches U1ST, D1ST, being opened, so that up-direction contactor 12 is energized. As the lift travels upwardly, intermediate reed switches are opened and closed by a magnetic actuator located on the lift car, without effect until the switch U4ST is opened. The contactor 12 is then de-energised to stop the lift at the fourth floor landing. If a call is now registered for the first floor, switch 1R closes to energize the down-contactor 11 and the lift travels downwardly until the reed switch D1ST opens. If the car stops between floors, one contactor is arranged to operate before the other when a destination is registered so that the car is driven to a landing whereupon normal service is resumed. In a modification, each reed switch is connected to a relay, the relay-contacts being connected in series between up and down contactors. Destination switches are associated with the relay contacts and the contactors, Fig. 3 (not shown). In a further embodiment, the destination control means comprises a pulse selector to which the reed switches are connected in parallel so that the selector is pulsed each time the car passes a floor until the selector reaches a condition corresponding to a setting for the selected floor whereupon the next reed switch operated is effective to stop the car at the selected floor, Fig. 4 (not shown). The reed switch means for each intermediate floor may comprise spaced switches to initiate slow-down in either direction as well as stopping operation.

Title: Improvements in or relating to the treatment of molten metals
IPC: C21C1/02
Filed: 1956-09-21
Abstract: 841,152. Treating molten metals. DIAMOND ALKALI CO. Sept. 21, 1956 [Sept. 23, 1955], No. 28961/56. Class 72 A method of treating molten metal comprises introducing the metal into a treating zone, imparting rotational motion to the zone to form a shallow stream of metal which is subjected to turbulent flow in the zone, adding a treating agent to the surface of the metal, and collecting molten metal and agent leaving the zone impelled by centrifugal force due to the rotational motion. As shown, a cylindrical furnace comprising a steel shell 2 having a refractory lining is mounted to rotate at high speed so that molten metal added through a runner 10 forms a layer along the inner surface of the lining; the speed of rotation of a furnace 1 foot in diameter and having a layer of metal 1 inch thick would be 350 r.p.m. A treating agent, preferably at the same temperature as the metal, is added through a tube 12 and forms a layer on the surface of the metal. The two layers, metal and agent, are discharged by centrifugal force over a guide ring 32 and collected in a hood where the metal is separated from the agent. A dam ring may be fitted in the furnace near the discharge end for the metal and the metal and agent may flow in counter current, Fig. 3 (not shown). Examples are given of desulphurizing pig iron by molten caustic soda or sodium carbonate and the cleaning of mercury by water.

Title: Improvements in or relating to methods of fitting heel end portions of shoe soles for the reception of heels and in or relating to means suitable for use therein
IPC: A43D8/48
Filed: 1937-10-25
Abstract: 506,335. Heel-seat fitting. BRITISH UNITED SHOE MACHINERY CO., Ltd., and HAZELTON, G. Oct. 25, 1937, No. 29036. [Class 17 (i)] Relates to the shaping of heel-ends of soles for the reception of heels of the kind described in Specification 501,057, the breast face having, adjacent the attaching face, a curved groove and a forwardly projecting tongue above the groove to be accommodated between the outsole and the shoe bottom. The shoe, having a short outsole thereon, may first be presented to a machine of the kind described in Specification 331,934, [Class 17 (i)], equipped with shouldering knives for forming the shoulders 7, Fig. 2, bevelling knives for forming the bevels 11, and, if desired, auxiliary knives for forming slits 15 at a distance from the shoulders 7 corresponding to the depth of the groove in the heel. The last mentioned cut may then be completed in a machine attached by a bracket 35 to the machine mentioned, the work being positioned by a tongue 31, Fig. 9, inserted under the sole and gauge members 33, Fig. 6, formed with inclined surfaces 171 engaging the bevels 11. These gauge members are slidable to and from each other by levers 159, 161 linked together and actuated by a treadle rod 167 depression of which moves the members apart. They are closed on the work by a spring 165. The chopping knife 27, Fig. 9, is carried by a slide 61, Fig. 8, urged upwardly by a spring 77 and depressed when desired by an eccentrically mounted roller 135 on a driven shaft 137. The slide 61 carries a tappet 87 secured to a shaft 85 also carrying a pawl 99 normally engaging a shoulder on a depending pivoted latch 95, which can be removed from the pawl by a push rod 105 pivoted to an arm 123 actuated by a handle 83. Springs 101, 103, 127 keep the parts in the position shown. Depression of the handle 83 trips the latch 95 allowing the tappet 87 to swing under the roll 135. The first descent of the roll chops through the sole, the tongue 31 serving as a chopping block. As the slide 61 descends, a surface carried by the pivot 85 depresses the rod 105 and allows the latch 95 to return and catch the pawl 99 as this ascends. The tappet 87 is thus tilted away from the roll 135 before the slide abuts against its upper stop 75. Specifications 310,822, [Class 17 (i)], 343,142, 464,277, and 501,447, also are referred to.

Abstract: 897,102. Electric analogue - calculating systems. AVEL CORPORATION GENEVA. Aug. 20, 1959 [Sept. 10, 1958], No. 29039/58. Class 37. In an apparatus for determining the risk of collision between two vessels A, B, Fig. 1, means are provided for determining the difference of the components of velocity of the two vessels normal to the mutual bearing line A, B and for indicating if such difference is substantially zero. Further means may be incorporated for determining whether the sum of the components of velocity along the bearing line is zero. The vessels A, B are proceeding at velocities VA, VB along the lines A, O, B, O. In vessel A a voltage proportional to the speed VB of the other vessel B is obtained from a wiper on a potentiometer VR1 and applied to a resolver R1, the rotor of which is driven by a course decoder DS1 responsive to the course CB of vessel B, to provide outputs VB sin CB and VB cos CR, a second resolver R2 the rotor of which is coupled to a local compass repeater converts these outputs to VB sin CR and VB cos CR since CB-CA = CR, and a further resolver fed with the mutual bearing from a radio compass converts the outputs from R2 to - VB sin DB and + VB cos DB. These outputs are compared in phase detector D2 and output detector D1 with the outputs VA cos DA and VA sin DA from a resolver R4 fed with the speed of vessel A. Specifications 874,261, 874,263 and 897,101 are referred to.

Title: Improvements in or relating to an insoluble cation-exchange resin and process for preparing same
IPC: C08F8/34
Filed: 1952-11-19
Abstract: Insoluble cation-exchange resins consist of sulphonated hydrolyzed cross-linked copolymers containing 3 to 15 per cent., on a molar basis, of a polyvinyl aromatic hydrocarbon which contains a plurality of vinylidene groups, an ester, preferably a lower alkanol ester, of acrylic or methacrylic acid, and optionally styrene, vinyl toluene or ethyl styrene as a third copolymerized constituent.  Polyvinyl aromatic hydrocarbons specified are divinyl and trivinyl benzenes and naphthalenes, and polyvinyl anthracenes.  Esters specified are methyl, ethyl, propyl, butyl and aliphatic polyhydric alcohol acrylates and methacrylates.  Sulphonation, which may be carried out before or after hydrolysis, is preferably effected by swelling the copolymer with a liquid such as acetone, toluene, ethylene dichloride, trichloroethylene, and perchloroethylene, and then sulphonating with concentrated or fuming sulphuric acid, or chlorsulphonic acid.  Hydrolysis may be effected by water if the copolymer has already been sulphonated, but may also be effected with aqueous hydrochloric or sulphuric acid, or aqueous sodium or potassium hydroxide.  The copolymers may be prepared in bulk, solution, or, preferably, aqueous emulsion with the aid of a mixture of gelatin and a dispersing agent to produce the copolymers in bead form. Copolymerization may be carried out with the aid of catalysts such as ozone, ozonides, benzoyl, acetyl, lauroyl, stearoyl, di-tert.-butyl and hydrogen peroxides, tert.-butyl hydroperoxide, and the salts of perboric, persulphuric, and perchloric acids.

Abstract: 488,465. Oscillographs ; cathode-ray tubes. SIEMENS & HALSKE AKT.-GES. Oct. 26, 1937, No. 29256. Convention date, Oct. 26, 1936. [Class 37] [Also in Group XL] Electro-cardiograms are produced by taking at least two heart-action potentials from a patient's body and applying to an oscillograph a resultant voltage that is proportional to the sum of the squares of the heart-action potentials. Component potentials at rightangles may be taken from breast contacts, these potentials after amplification being applied to square-law rectifiers, the square root of the resultant potential being formed and applied to an oscillograph. Three component potentials may be collected, as from the Einthoven triangle contacts, the resultant voltage being proportional to the sum of the squares of these potentials, and the resultant can be applied to an oscillograph responsive to an inverse-square function of the applied voltage. An action-potential can be taken between the breast and back of a patient, that is, in a plane at right-angles to the plane in which the above-mentioned contacts lie. In Fig. 2, the component potentials b, c are applied to amplifiers 4, 5 and rectifiers 6, 7 having a square-law input-output characteristic. The squares of the voltages are summed across impedances 8, 9 and applied to arcuate electrostatic deflecting plates 10, 11, the curvatures being related to deflect the beam in proportion to the inverse-square of the applied voltage. An ordinary oscillograph can be employed and the square law scale avoided by supplying the resultant squared voltage to a device having an inverse-square characteristic. If an electromagnetic oscillograph is used, it can be given an inverse-square response by shaping its polepieces.
