Title: Carburettor automatic choke mechanism
IPC: F02M1/10
Filed: 1963-07-24
Abstract: 965,526. Spray carburetters. FORD MOTOR CO. Ltd. July 24, 1963 [Aug. 2, 1962], No. 29242/63. Heading F1B. A carburetter choke valve 17, having a magnetic latch 49 holding it in the closed position, is connected through a spring 28 to a thermally responsive element such as a bimetallic spring 23, the spring 28 permitting the valve to open a predetermined amount under the effect of suction. The choke valve lever is connected to a lever 44 fast on a spindle 29 carrying a lever 31 with an arm 32 engaging a slot 34 in a lever 25 loose on the spindle, the spring 28 engaging tangs 33, 36, on the levers 31, 25, to urge the arm 32 against the side 34a of slot 34. The bimetallic spring 23 is connected to the arm 24 of lever 25 and rotates lever 25 anti-clockwise when cold to close the choke valve 17. The magnetic latch 49 increases the force on the choke valve when it is in or near its closed position. When the engine starts the increased suction opens flap 17 and the spindle 29 rotates, against the force of spring 28, within the limits of the lost motion slot 34. If the suction increases, the valve 17 opens further and arm 32 rotates lever 25 against the force of spring 23; if there is a subsequent decrease in suction, valve 17 returns to a position determined by the temperature of spring 23 and, if necessary, can return to the closed position.

Title: Method and Apparatus for High Temperature Dyeing or Finishing of a Fabric Material.
Inventor: BLOUNT CHARLES
IPC: D06B19/00
Filed: 1968-06-19
Abstract: 1,164,956. Textile treatment apparatus. UNITED PIECE DYE WORKS. 19 June, 1968, No. 29273/68. Heading D1L. Open width materials are padded with a dye or finishing material, wound on a roller and then placed, with the roller, into a pressure vessel. After raising the temperature and pressure in the vessel, the material is wound onto a further roll in the vessel. The padding may be by rollers 19 after an immersion treatment at 17A or by retaining a part of liquid in a nip. The rollers may be carried on rails 28, 25 so that the transporting of the loaded roller from the loading position to the pressure treatment position is facilitated. One pressure vessel 23 may serve more than one set of feed rollers and thus a semi continuous process can be practised, one set being loaded with padded goods whilst another set is in the pressure vessel. A heater 42 prevents drips due to condensation.

Abstract: 466,006. Metallic-vapour apparatus. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Oct. 28, 1936, No. 29346. Convention date, Oct. 28, 1935. [Class 39 (i)j A discharge device of the hotcathode metal-vapour type, such as a mercury-vapour rectifier, has a main supply of a vapourforming substance, and, when cold, an auxiliary supply of the same substance in such a position that, on heating up, this auxiliary supply evaporates to provide a safe operating vapour pressure for the discharge space before evaporation of the main supply can do so, the auxiliary supply being such that the vapour pressure is maintained therefrom until the main supply is sufficiently heated. Preferably the auxiliary supply is located in a tubular extension 2 of the hottest part of the envelope near the cathode. When the tube is switched off the part 2 cools most rapidly and a large part of the filling condenses therein. The heating-up time is shortened, without producing such a high vapour pressure that backarcing occurs.

Title: Improvements in or relating to waterproof coatings
Filed: 1946-10-04
Abstract: Finely powdered materials waterproofed by coating them with an organosilicic derivative are bonded to an article to be water-proofed by means of an adhesive.  Specified powders are silica, talc, kaolin, and fuller's earth, and the organisilicic derivative may be a resin or an oil.  The powder may be water-proofed by treatment with a solution of organosilicic resin and then heating, or by treatment in the cold with methyl chlorosilicanes.  Water-proofing solutions may contain methylchlorosilanes or a methyl-phenyl-organosilicic resin in such solvents as benzene and isopropyl alcohol while benzoyl peroxide may be added if an organosilicic oil is used.

Title: Improvements in or relating to methods of manufactuing hardened gear wheels composed of several parts and to the gear wheels made by the method
IPC: C21D9/32
Filed: 1933-10-26
Abstract: 412,090. Toothed wheels. MAAGZAHNRADER & MASCHINEN AKT.-GES., 219, Hardstrasse, Zurich, Switzerland. Oct. 26, 1933, No. 29746. Convention date, Sept. 13. [Class 80 (i).] In a method of making a hardened gear wheel composed of several parts, such as a twopart gear 1 for use in an electrically-driven vehicle, the teeth are first formed in the undivided blank, which is subjected to cementation and hardened and is then provided with registering-means for relative location of the parts of the wheel, the wheel being finally severed at the joint. The joint is preferably made along two arms 2 of the wheel which have hollow spaces 4 and the plane of the joint extends through opposite tooth gaps. The teeth are cut in the rough blank which is then subjected to cementation and on subsequent turning of the wheel body the carbonized material is removed so that, after hardening, holes 5, 6 may be drilled along the line of the proposed joint. The holes are accurately fitted with pins. The wheel is then severed by milling or sawing and holes for the connecting bolts 7 are drilled. The two parts when connected will be accurately registered by the pins 5, 6 and the pins 6 serve also to resist the thrust of the bolts 7. The gear teeth may now be finished by lapping. The pins and holes may be replaced by other registering means. Instead of removing the carburized material near the joint after cementation, the joint portion may be covered with protecting material during cementation so that it remains soft during subsequent hardening.

Abstract: 635,953. Friction clutches. DANA CORPORATION. Nov. 11, 1947, No. 29975. Convention date, May 17, 1944. [Class 80 (ii)] The normal manually-operated throwout levers 10 of a motor vehicle plate clutch are actuated for clutch engagement by centrifugal weights 15 through pre-loaded individual compression springs 13 and a stamped sheet metal spring loading ring 14 resiliently supported by the springs 13. Headed pins 47 limit the extension of the springs 13 which act between recesses 48 on the levers and radial lugs 43 on the ring. The levers 10, which are of sheet metal, are pivoted to a stamped sheet metal back plate 11 and co-act with the presser plate 9 through adjustable bolts 21. Each weight 15 is slidably pivoted, through rollers 32, in a pair of lugs 27 projecting axially from the back plate 11, and carries rollers 35, 36 reacting between the plate 11 and a lug 29 projecting radially and rearwardly from the ring 14 to locate between the lugs 27. The weights 15 are notched out on their inner edges to clear the lugs 29, and are so disposed that, when they abut the plate 11 at the outward limit of their travel, the line joining the centres of the rollers 35, 36 still makes an angle with the clutch axis such that the springs 13 are effective to collapse the weights. The back plate 11 and presser plate 9 have cut-aways 45, 46 opposite the lugs 43 to allow clear working of the ring 14, and the springs 13 have always sufficient reserve compressibility to allow manual clutch disengagement whatever the position of the weights 15.
