Abstract: 726,978. Temperature-responsive actuating elements. GENERAL ELECTRIC CO. Feb. 4, 1953 [Feb. 8, 1952], No. 3168/53. Class 64 (2). [Also in Group XXXVII] The thermal unit of an electric relay (see Group XXXVII) comprises a bellows 2 connected by a capillary tube 3 with a boiler 1. To ensure consistent operation of the relay, the unit 1, 2, 3 is filled with a vapourizable liquid such that the liquid is always in contact with its own vapour within the boiler, and to this end the unit is filled and sealed at 100 ‹C. with the bellows fully compressed. On release of the bellows, the resulting slight expansion causes formation of a vapour pocket in the boiler at room temperature. A preferred liquid is para-cymene having a boiling point of 177 ‹C., but aniline, o-dichlorobenzene, or chloro-methyl-benzene may be used. The upper surface of the boiler 1 is blackened and urged by a leaf spring 23 into thermal contact with an electric heater strip 16. The boiler comprises a cylindrical upper portion of copper and phosphor bronze, silver soldered to a stainless steel base 1a, an annular support member 4 preventing collapse of the boiler, Fig. 6. The bellows 2 of brass or phosphor bronze is mounted by a stainless steel end plate 2a having upturned lugs 2b, 2c for the reception of mounting screws.

Filed: 1975-01-24
Abstract: 1490163 Enhancing stretchability of wool W L WASLEY and A G PITTMAN 24 Jan 1975 [24 Jan 1974] 3247/75 Headings D1B and DIP The stretchability of a wool-containing textile is enhanced by contacting the textile with an alcohol selected from ethylene glycol, glycidol, propylene glycol, glycerol and diethylene glycol under particular conditions of time and temperature. When the alcohol is ethylene glycol or glycidol, the contacting is effected at a temperature (TC) of 120- 180C and for a time (t seconds) governed by the limits T=165-(16.7 log 10  t) and T= 185-(16.7 log 10  t). When the alcohol is propylene glycol, glycerol or diethylene glycol, the contacting is effected at 140-180C and for a time governed by the limits T=180- (16.7 log 10  t) and T=196-(16.7 log 10  t). The textile may be contacted with the liquid either by immersion in the liquid at the appropriate temperature or by impregnation with the liquid followed by heating in an oven or chamber to the desired temperature. The treatment is terminated by cooling the textile, removing the residual alcohol e.g. by washing with water, and drying. The process may be used in conjunction with dyeing, shrink proofing or setting treatment, and the treated textiles exhibit increased bisulphite settability, and dyeability e.g. with chrome, neutral pre-metallized, acid pre-metallized, acid levelling and fibre reactive dyes. The alcohol may contain a small quantity of anti discolourant e.g. p-toluene sulphonic acid. The preferred treatment is at 150C for 30-60 seconds. The textile may be all wool or a wool blend containing at least 25% wool and may be in the form of woven, non-woven or knitted fabrics, bulk fibres, yarns, sliver, roving, or top. The blends may be with natural cellulose or cellulose derivative fibres, animal hair, polyester, polyurethane or polyacrylonitrile fibres.

Title: Winch for the operation of grabs, buckets and the like
IPC: B66C3/12
Filed: 1934-02-01
Abstract: 414,587. Winding apparatus for lifting &c. SOC. FRANCAISE DE CON. STRUCTION DE BENNES AUTOMATIQUES, 10, Rue de Nancy, Le Havre, Seine InfÚrieure, France. Feb. 1, 1934, No. 3389. Convention date, Feb. 13, 1933. [Class 78 (v).] A winch for the operation of automatic buckets or grabs especially for the excavation of shafts or wells is characterized by the employment of two drums 1, 2, Fig. 2, the diameter of which equals the length of cable necessary for closing or opening the grab and of a device Fig. 3 connecting the drum, and limiting their relative movement to one revolution. The cable for lifting and closing the grab or bucket is wound on drums and that for opening and retaining the bucket on drum 2. The drums are loose on a shaft 3 mounted in end plates 4, 5. The diameters of the drums are alike and their diameters are such that one revolution suffices to open or close the bucket completely. When the bucket is raised in the direction f<1>, Figs. 2, 3, a tappet 7 is in contact with the left hand face of a tappet 8 of the drum 2 which is not braked and will be driven at the same speed and direction thus winding the opening and lifting cables 13, 14 together to support the weight of the bucket. At the upper part of its course the drum 2 is braked by pressing a cam 27 on a wheel 6 at the same time the drum 1 is released by operating a lever 28 connected with a friction driving wheel 21 working on the extension 20 of the drum 1. At once the bucket is opened for instance by a heavy central piston slidably contained therein giving the drums a movement in the, direction f<2>. When the drum 1 has completed a revolution the bucket is entirely open and the tappet 7 again contacts with the tappet 8 but this time on the right-hand face. In passing a pawl 9, Fig. 3, is raised by the tappet 7 and is brought back by a spring and comes to the rear of the tappet and holds it fast. The two drums are again connected the bucket being open, the lever 28 is slightly operated releasing the brake 6 but holding the drive 21 away from the projection 20 on the drum 1. Drum 2, under the action of the cable 13, is rotated in the direction of the arrow f <2>. Drum 1 is also similarly rotated and cable 14 is unwound avoiding traction on the drum and making it impossible for bucket to close during its descent. In order to anchor the winch a device 15, Fig. 4, made up of three or four uprights has two uprights fixed on a frame which may consist of U-shaped iron bars 17. Holes 18 of oval shape house tubes 15 forming the uprights.

Filed: 1958-02-03
Abstract: 843,870. Determining physical qualities of materials. RICHARDSON & STARLING Ltd. Jan. 28, 1959 [Feb. 3, 1958], No. 3478/58. Class 37 A Moisture Detector of the kind comprising a pair of electrodes, a current responsive instrument and a source of current comprises a carrier for the instrument provided with a handle and two pointed electrodes which can be applied to the material to be tested by holding the casing in one hand. In the embodiment shown, the casing 1 with a handle 11 houses a meter 2 and a power supply which may consist of two 30v dry batteries. The electrodes 3 are clamped by screws 4 into spring loaded holders 5, such that pressure on the electrodes completes the circuit between the contact screws 9 and 9a. A variable resistor is included in the circuit so that full scale deflection of the meter can be set to correspond to 100% saturation of the material under test. Where the readings are likely to be effected by electrolysis, an A.C. supply derived from an oscillator may be used. In modifications of the instrument the circuit may be controlled by a hand operated switch. As described in the Provisional Specification the shape of the electrodes may be varied, or the ends of the electrode holders used directly as electrodes.
