Title: Improvements in or relating to machinery for laying and recovering submarine cable
Inventor: CLARKE ERIC FIFIELD STUART
IPC: B66D1/74
Filed: 1961-05-04
Abstract: 959,466. Winches. POSTMASTER GENERAL. April 30,1962 [May 4, 1961], No. 16254/61. Heading B8B. In a cable winding device for cable laying and recovering, the back-tensioning mechanism such as a sheave 19, Fig. 1, is drivingly coupled to the main winding drum 1 through a free-wheel device 8, 9 and through a slipping device such as an epicyclic gear 20 permitting control of the torque transmitted to the sheave 19. In operation, during cable laying, the cable 3 passes from the cable tank, once round the sheave 19 and then makes several turns round the main drum 1 before passing through ancillary laying equipment. In this direction of rotation as shown by arrows 36 the interconnecting shafts 5, 7 are so driven that the freewheel device 8, 9 does not transmit a drive to the sheave 19 which is braked by a band brake 22 operating on the housing 21 of the epicyclic gear. A pawl 13 engaging the freewheel 9 prevents its reverse rotation during the braking operation. During cable recovery the direction of rotation of the drum 1 is reversed and the sheave 19 is driven through the freewheel 8, 9 and epicyclic gear 20, the speed and torque being controlled by adjustment of the brake 22. A measurement of the torque transmitted may be obtained through a meter 30, Fig. 2 (not shown), adapted to measure the torque on a mounting plate for the brake 22 and which may be adapted to control the braking. The cable 3 is pressed into contact with the sheave 19 by means of a jockey roller 32 on one arm of a double arm lever 33 which is loaded by a weight 35. In modifications the epicyclic gear may be replaced by a magnetic clutch and the sheave 19 may be replaced by endless track gripping devices.

Filed: 1927-10-14
Abstract: 291,725. Naamlooze Vennootschap Algemeene Norit Maatschappij. Oct. 16, 1926, [Convention date]. Divided on 279.104. Carbon.-Gas activated carbon which has been derived from carbonaceous material of vegetable, animal, or mineral origin, by the action of superheated steam or other gases or vapours at high temperatures, may be further activated by treatment with activating, oxidising, or purifying non- alkaline chemicals and subsequent heating to incandescence, without previously washing to remove any part of the chemicals. These chemicals may be subsequently extracted or washed out from the carbon. Active carbon impregnated with an activating agent may be heated by causing an electric current to pass through the mixture whereby the products of electrolysis of the added chemicals may still further increase the activity of the carbon. Spent active carbon may also be treated by this process. As activating agents the following are specified :-phosphoric, hydrochloric, and nitric acids, chlorides and compounds from which chlorine is evolved, phosphates, nitrates, sulphates, bisulphates sulphides, peroxides, perchlorate and other per salts and oxidisers. Specifications 155,610 and 264,854 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use in the process of potassium and sodium hydrates and carbonates and organic acids and salts, and the regeneration of used active carbon.

Title: Polymers derived from unsaturated alicyclic compounds
IPC: C08F36/00
Filed: 1966-04-14
Abstract: Linear polymers consisting of, or comprising, butadiene units, are made by polymerizing an alicyclic compound which contains at least one alicyclic ring which may be substituted, the ring having at least eight carbon atoms and one, two or three carbon-to-carbon double bonds in the ring, by contacting the alicyclic compound with a catalyst comprising an admixture of (a) an organometallic compound of a metal of Groups Ia, IIa, IIb, and IIIa of the Periodic Table of elements, and (b) a salt of Mo or W.  The polymerization is effected by conventional low-pressure methods. The Specification contains an extensive list of alicyclic compounds.  Exemplified alicyclic compounds are cyclo-octene, cyclododecene, cyclododecatriene, and 1,5-cyclo-octadiene.  The polymerization reaction may be controlled by incorporating in it release agents which upon heating deactivate the catalysts.  By suitable selecting the appropriate alicyclic compound containing two or three double bonds the following linear polymers may be obtained, a polymer comprising repeating units of the formula -CH2-CH = CH-CH2-(CH2)4-, alternating copolymers of butadiene and butylene, alternating terpolymers of butadiene-1,3, styrene and ethylene, alternating copolymers of butadiene and isoprene, alternating terpolymers of butadiene-1,3, acrylonitrile and ethylene, an alternating terpolymer of butadiene, vinyl chloride or vinyl acetate and ethylene, 1,4-polybutadiene containing less than 0.3% of 1,2-polymer units and comprising alternating cisand trans-vinylene groups, and a polybutadiene having less than 0.2% of 1,2-vinyl structure, the remainder having a 1,4-structure of which 20 to 90% is in cis-1,4-configuration.  The polymerization is preferably effected in bulk, and fillers such as carbon black, pigments &c., may be present.  Moulded products may be conventionally vulcanized or vulcanized by an ionizing radiation.

Title: Variable speed fan drive
IPC: F01P7/04
Filed: 1947-06-23
Abstract: 624,546. Variable-speed gearing. JACK & HEINTZ PRECISION INDUSTRIES, Inc. June 23, 1947, No. 16536. Convention date, July 17, 1946. [Class 80 (ii)] [Also in Group XXVII] An engine cooling fan is driven by an expanding pulley gearing automatically controlled by hydraulic means in response to variations in temperature of the engine cooling medium. A fan 1 has a portion of its boss 2 shaped to form one flange of an adjustable pulley, the other flange 6 being splined to a shaft 5 and loaded by a spring 8 to engage a V-belt 7. A gear 12, driven from the engine, is rigid with a hollow shaft 13 on which is rigidly connected one flange 10, and slidably mounted the other flange 11, of the driving pulley. The flange 11 is connected by a transverse pin 24, sliding in a slot 18 of the shaft 13, to a rod 20 connected through a bearing 21 with a piston 23 in a cylinder 25. Oil from the engine is admitted under the control of a valve 30 from a passage 26 through a passage 28 to the cylinder, and from the cylinder through passage 29 to the exhaust 27. The valve 30 is moved through linkwork by a bellows 33 responsive to the temperature of the cooling medium and, through the pipe 49, to the movement of the bellows 50 which are moved by the bellows 52, 53 being responsive to ambient temperature and manifold pressure respectively. The bellows 33 is connected off mid-length of the lever 35 which is connected at one end to the valve 30 and at the other end to a link 44 connected to a lever 39 bearing at one end on an extension 43 of the piston 23 and loaded by a spring 40 at the other. The action is such that as the bellows expand the valve 30 allows pressure oil to move the piston 23 upwards and thus through the rod 20, to move the flange 11 to increase the effective diameter of the driving pulley and thus increase the speed of the fan. The lever 39 follows the movement of the rod and shuts the valve 30 to maintain a balance between the temperature and the fan speed according to the position of the piston 33.
