Abstract: 907,635. Making trimmed rubber mats. GOODYEAR TIRE & RUBBER CO. Nov. 14, 1960 [Nov. 23, 1959], No. 38979/60. Class 87(2). A mould for shaping and vulcanising a mat comprises a mould member 1 with a cavity insert 3 having the contour and configuration of the mat, a trimming edge 10 on the member extending round the periphery of the mat, a sealing groove 7 on the inside of the trimming edge 10, and another sealing groove 11 on the outside of the trimming edge, both grooves extending round the periphery of the mat, and both being connected to independent vacuum chambers 9 and 13 by bores 8 and 12 respectively. The insert 3 is of hard rubber, aluminium, or epoxy resin patterned as desired. The sealing groove 7 is made in an insert of material with good thermal conductivity and another insert 14 of poorly conducting material is placed round the periphery of insert 6. In operation a sheet of rubber stock 28 is positioned on the mould and the vacuum in chambers 9 and 13 draws the stock to the shape shown in Fig. 2, with the air from above the insert 14 being pumped out through bores 15. The mat stock is trimmed by rolling a wooden roller over the edge 10, the excess stock being removed after release of the vacuum in chamber 13, and the mat vulcanised by heat and pressure. In a modification, Fig. 3 (not shown), the sealing groove on the outside of the trimming edge is made deeper and placed close to the trimming edge, so that when the vacuum is applied the mat stock is drawn tightly over the edge and automatically severed. In a further modification, Fig. 4 (not shown), the insert 6 is made of a ceramic material with a trimming edge containing an electrically heated wire, so that the stock is burned through at the edge to effect the trimming.

Patent GB-929225-A (GB)
Title: Encapsulation of lipophilic materials
IPC: A61K9/50
Filed: 1959-11-26
Abstract: Finely divided solid or liquid lipophilic material is encapsulated by dispersing it in an aqueous solution of a linear macromolecular synthetic polymer comprising both lipophilic and hydrophilic units and inducing liquid/liquid phase separation of the polymer by addition of an organic or inorganic solubilizing salt thus forming a "mantle" of polymer about the particles and subsequently adjusting the pH to reduce the solubility of the mantle material and separating the capsules from the aqueous liquid.  Preferred polymers are the hydrolysed styrene-maleic anhydride copolymers including those of general formula (-R-R1-)n, wherein R represents lipophilic polymer units p  of which more than 70% are styrene residues, the remainder, if present, being those of, e.g., acrylonitrile, acrylic acid, methacrylic acid, itaconic acid, vinyl chloride and vinylidene chloride and R1 represents hydrophilic polymer units of which more than 50% are maleic acid residues (preferably more than 70%) and the numerical ratio of R : R1 being from 1 : 1 to 4 : 1, preferably 1 : 1 to 1.2 : 1, and n is an integer from about 90 to 1000 and the molecular weight ranges from about 90 to 1000 and the molecular weight ranges from about 20,000 to 200,000. Other polymers stated to be of use are the carbohydrate acetate phthalates, sulphonated polystyrenes, polymethacrylic acid, methyl vinyl ether-maleic acid and styrene maleic acid amide copolymers.  The solvent for the polymer may be water or mixtures thereof with lower alkanols, lower alkylene glycols and lower alkyl triols and may also contain a solubilizing agent, e.g. a polysaccharide, e.g. alginates and those derived from Irish moss. The capsules formed may contain materials which render them useful in many fields, e.g. for coating films or sheets with sticky, oily, greasy or unstable materials useful, for example, in the printing art.  Magnetized particles may be incorporated and afford products useful in information storing devices.  Fertilizers, plant growth hormone preparations, pesticides, bactericides, catalysts, pharmaceuticals and food additives may also be incorporated in the capsules which protect or preserve the materials therein and/or prevent detection of their objectionable taste or odour.  A specific example describes a product in which cellulose acetate phthalate encapsulates a solution of 2,4-dichloro-phenoxyacetic acid in white mineral oil and which functions as a long-acting weed-killer.  Specification 751,600 is referred to.

Title: Self-Adjusting Clutch-Actuating Mechanism.
IPC: G05G23/02
Filed: 1968-08-28
Abstract: 1,188,893. Clutch control. FORD MOTOR CO. Ltd. 28 Aug., 1968 [30 Sept., 1967], No. 41025/68. Heading F2L. Automatic adjustment for wear is made in the control linkwork of a spring-applied clutch by decreasing the length of an adjustable link 25, the link comprising a push rod 10 received in a cylinder 34 and spring-biased away from the cylinder by a spring 15 stronger than a spring 21 acting on the throw-out lever 4, the cylinder communicating with a liquid reservoir 18 through bores in the reservoir and cylinder forming a valve 36, so that initial depression of the pedal 1 to move the lever 4 against the spring 21 to load the clutch thrust bearing 5 causes the push-rod 10 to move the cylinder 34 through spring 15 to close valve 36 prior to loading of the bearing 5 preventing relative movement between rod 10 and cylinder 34. On wear occurring in the clutch, the bearing 5 is loaded prior to valve 36 closing and, since the clutch engaging springs are stronger than spring 15, the rod 10 moves into cylinder 34 and a crank arm 12 pivoted on the rod and cylinder is turned, and the clutch disengaging force is transmitted from a stop 38 on the rod to a finger 11 on cylinder 34. On subsequently releasing the pedal, the rod 10 moves away from the cylinder 34 turning the crank-arm 12 back so that a pawl 13 thereon co-operates with ratchet teeth on an adjustment nut 14 screwed on the cylinder and abutting lever 4 to turn the nut and move it to the left to shorten the link. Again, Fig. 6 (not shown), the link includes a toggle lever arrangement (47) which, with the pedal released, is held in a partially collapsed position by a spring 55 and stop 70 but which, when the clutch is correctly adjusted, is moved by the spring (55), on depressing the pedal, to its fully extended position, to transmit thrust, prior to the clutch release bearing being loaded. Should wear occur, the load point is reached before the toggle lever is fully extended so that the lever collapses and the thrust is transmitted from the push-rod to the throw-out lever by a stop on the rod abutting directly the member operating on the throw-out lever. On subsequently releasing the pedal, a pawl on the toggle lever arrangement co-operates with ratchet teeth on an adjustment nut 73 to decrease the length of the link.
