Title: Improvements relating to the treatment of wool
Inventor: FRIEDL ARNO RUDOLPH
IPC: D06M15/693
Filed: 1965-04-13
Abstract: Wool is rendered resistant to shrinkage and setting by treating it with a solution of a carboxylated rubbery polymer of a conjugated diene to obtain a take up not exceeding 5% based on the weight of the wool of the carboxylated polymer, with the proviso that if less than 5% of the available double bonds of the polymer have been modified to give groupings containing carboxyl radials at least 0.1% by weight based on the weight of the polymer of a dithiol is present in the solution.  The term a carboxylated rubbery polymer denotes a substance derived from a rubbery polymer having carbon-to-carbon double bonds in its molecule but having a minor proportion of those bonds modified by conversion into groupings containing carboxyl radicals.  The carboxylated rubbery polymer used may be one derived from a homopolymer of a conjugated diene, e.g. butadiene, isoprene or dimethylbutadiene, or from a copolymer or interpolymer of at least 50% by weight of a conjugated diene and a vinyl monomer, e.g. styrene, vinyl toluene or divinyl benzene, by reaction with a thiol-carboxylic acid, e.g. thioglycollic acid.  When a dithiol is used this may be ethylene glycol dimercaptoacetate or hexanediol bis-thioglycollate.  The dithiol may be used even when more than 5% of the double bonds of the polymer have been modified.  The polymer may be applied to the wool as a solution in an organic solvent, e.g. toluene, benzene, trichloroethylene, perchloroethylene or white spirit, and may be present in the solution in a concentration of 0.5-5% by weight. After impregnation the wool may be squeezed or centrifuged and optionally subjected to a short heat treatment, e.g. 5 minutes at 100 DEG C.  Fibres, yarns, rovings, slivers or woven, non-woven or knitted fabrics comprising wool fibres alone or in admixture with other natural and/or artificial fibres may be treated. Prior to the treatment the wool may be treated with a reducing agent, e.g. a sulphite or bisulphite or thioglycollic acid.

Title: Improvements in or relating to apparatus for converting reciprocating into rotary motion or vice versa
IPC: F16H25/14
Filed: 1936-06-05
Abstract: 476,247. Converting reciprocating into rotary motion, and vice versa; cams. MARCH, C. E. M. June 5, 1936, No. 15747. [Classes 80 (i) and 80 (iii)] [Also in Group XXVII] Apparatus for converting reciprocating into rotary motion and vice versa, in internal-combustion and steam engines, pumps, &c., comprises the combination with a reciprocating member arranged to slide in or on a guide, of three similar cams coupled together so as to rotate, two of them at the same speed as, but in opposite direction to, the other and each engaging a part of or a follower on a reciprocating member, the arrangement being such that as the cams rotate, they cause reciprocation of the reciprocating member, the side thrust of one cam being balanced by that of the others. As applied to a two-stroke internal-combustion engine, three cylinders B are mounted on a casing A carrying bearings for a shaft D to which is secured a cam E of approximately triangular form. On each side of cam E is a cam F of similar form mounted on a bearing F<1> supported on a sleeve F<2> secured to the casing. Rigidly secured to the inner end of each sleeve F<2> is a spider F<3> carrying radial pins on which are mounted bevel pinions G each of which engages corresponding teeth on the cams E and F which therefore rotate in opposite directions. Each piston H has a forked inner end carrying three rollers H<1> the centre one of which engages cam E whilst the outer two engage the cams F. The number of strokes performed by the piston per shaft revolution, in this case three, may be varied by employing cams of different contour. The rollers may be maintained in contact with the cams by connecting the inner ends of adjacent pistons by a lever pivoted to the casing.. Specification 425,987, [Group XXVII], is referred to.

Title: Improvements in the method of ventilating mines, and apparatus therefor
IPC: E21F1/18
Filed: 1923-06-18
Abstract: 212,802. Heise, F. June 18, 1923. Ventilating mines; air, treating; forced ventilation. - Mines are ventilated by utilizing the heat derived from condensation of exhaust steam from mine engines to produce an upward flow of air in the upcast shaft. As shown, the exhaust steam from a jig conveyer engine a is carried by a pipe c to a radiator d, of known type, arranged in the upcast b, the heat liberated by the condensation of the steam producing an updraught in the shaft b. The condensate discharges into a sump f and the pipe c is fitted with a valvecontrolled nozzle g through which steam may be injected into the air coLumn to maintain the desired degree of humidity and also to impart a further upward drive. The lower part of the Figure shows an arrangement in which steam from a pump engine h is conveyed to a radiator l arranged in an air-way m, the necessary suction being maintained by an air pump n and a pump o being provided for discharging the condensate. In a further modification, the exhaust steam from a pump engine is passed through a water-cooled condenser and the cooling water is circulated by a pump through the radiator. Fans may be used to assist the ventilation. In cases where the exhaust steam is utilized for other purposes, the regular part of the supply is used for that purpose and the "peak" current for heating the radiators.

Title: Improvements in or relating to torque meters
Inventor: HEGARTY WILLIAM
IPC: G01L3/12
Filed: 1965-04-15
Abstract: 1,129,582. Photo-electric torqne measurement. SAUNDERS ROE DEVELOPMENT Ltd. March 15,1966 [April 15,1965], No.16427/65. Heading G1A. The torque of a shaft is measured using a photo-electric system, sensitive to the amount of angular twist between two positions along the length of the shaft and utilising a self-luminous type of light source. In the embodiment described the shaft 1 is mounted in a bearing 13 associated with a cylindrical housing 12 fixed in space by its connection to supports 15. At equal intervals around the inside of the cylindrical housing 12 are spaced four photo-cells 17 (cadmium sulphide photoconductors). Attached to the shaft 1 at a position within the housing 12 is a flange 9 carrying the light source 4, phosphor-coated envelope containing radio-active gas to activate the phosphor. The light source 4 thus rotates with the shaft 1 radiating light radially outwards of the shaft. A cylindrical member 10 attached by means of a tube 5 to a point 6 further along the shaft, and positioned between the source and the photo-cells, has a slot 11 cut out of it so that when the shaft is not loaded and there is no angular twist between the effective points of attachment of the member 10 and the source 4, the slot passes a maximum amount of light to a photocell. During rotation of the shaft, the source and slot rotate together with the shaft so that the photo-cells are illuminated successively. The cells are connected in parallel to a current source 18 and galvanometer 19 so that the total cell output alternates between a high and low value as the shaft rotates. Any torque on the shaft results in the slot 11 being not completely aligned with the source and a photo-cell and a resultant drop in the high current level is obtained. Since the galvanometer reads the r. m. s. value of the alternating signal, its indication is continuously representative of the torque on the shaft, except at very low speeds and when the shaft is stationary. Modifications are possible, e.g. continuously adjacent or annular photo-cells, or more than one source or an annular source. Reference photocells may be provided to compensate for source intensity decreases and temperature variations. Photo-voltaic cells may be used instead of photo-conductors. The apparatus can be adapted for use as a tachometer while giving torque readings so that power measurement is also possible.
