Filed: 1922-07-15
Abstract: 209,528. Barnes, J. E. L., (Miller Rubber Co.). July 15, 1922. Vulcanizing.-Rubber articles are vulcanized by incorporating with the rubber compound one of two ingredients which, in the presence of heat, will coact to effect vulcanization, applying the other ingredient to the surface of the rubber compound and applying heat to cause the surface ingredient to penetrate the mass and so effect vulcanization. Sulphur may be incorporated with the rubber compound, and an accelerator, such as the compounds of aliphatic amines or piperidine with carbon disulphide, applied to the surface, or vice-versa. The surface ingredient may be in powder form mixed with starch powder. When goods are made by the dipped process, one of the ingredients may be incorporated in the rubber solution and the other dusted on the surface. When the accelerator is water soluble, the sulphur-bearing rubber compound may be immersed in a hot aqueous solution of accelerator to effect vulcanization. Reference has been directed by the Comptroller to Specification 174,915.

Patent GB-293797-A (GB)
IPC: B41D1/00
Filed: 1928-07-05
Abstract: 293,797. Maschinenfabrik Augsburg- Niirnberg Akt.-Ges. July 12, 1927, [Convention date]. Embossing-machines.-In a hydraulic press for impressing stereotype matrices, in which the main pressure piston v is raised rapidly initially by a separate piston d of small cross-sectional area operated from a pump a, and a valve k is opened when a certain pressure is reached under the piston d, so that pressure is applied directly to the main piston v, the suction valve b of the pump is automatically lifted when the desired pressure is attained so that no further increase of pressure takes place. The pump a draws From a t,ank h through the valve b and discharges through a valve c to operate the pistons d, v. As the piston v rises under the action of the piston d, water is drawn from the tank h into the chamber beneath it, through a valve g. When the pressure on the piston d reaches the requisite amount, the valve k opens against the action of a spring i so that pressure is applied to the piston v and the valve g is closed. During further increase of pressure, a control piston n is forced downwardly so as to tilt a lever m pivoted at o and having a weight l adjustably mounted thereon. Movement of the lever m causes the lifting of the suction valve b of the pump a by means of a rod p thereon, so that no further increase of pressure takes place. When the impressing operation is completed, the tilting of the lever m is increased either by hand or by releasing the weight e and moving it to the right, so that a relief-valve ball r is released by a second rod q which has thereon a collar s engaging subsequently the valve g so as to allow the pressure water to flow back into the tank h, and the piston v and table e descend. The weight may be secured by a catch to an adjustable slide u on the lever m, and may be released so that as the lever m tilts, it slides to the right so as to cause the further tilting required. In order to prevent premature opening of the valves r, g due to the momentum of the parts m, n, an additional weight t is provided on the lever, which normally rests on the ground and is carried by lever m only after it has tilted sufficiently to open the suction valve b. Alternatively to the weight t, the weight l may have a centre of gravity below the lever m so that tilting of the lever causes the turning moment of the weight about the pivot o to increase slightly.

Abstract: 909,341. Snap-action switches; cam-operated switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 19, 1959 [June 23, 1958], No. 20074/58. Class 38 (5). [Also in Group XIX] A switch for intermittent circuit making comprises first and second rotatable members connected together by a resilient and powerstoring coupling, latching and latch-releasing means for temporarily preventing rotation of the second member during each revolution of the first member and a cam arranged for rotation by the second member to control a contact in said circuit. The switch may be connected to control a counter. As described, a driving shaft 1 drives via a gear G, a shaft 101 carrying a first rotatable member 106 connected to a second rotatable member 105 via a resilient and power-storing coupling comprising a spiral spring 107 having one end connected to the member 105 by a pin 105c and the other end connected to the member 106 at 106b. Latching means comprise a leaf spring 111 having one end fixed and the other end adapted to prevent rotation of the member 105 by engaging a pin 105d. As the member 106 rotates, a peg 106c projecting therefrom deflects the spring 111 to release the pin 105d so that the member 105 rotates under the action of the spring 107 which has been tensioned by the preceding rotation. After a predetermined angular movement, the member 105 is arrested by a second spring 115 secured to it engaging pin 106b on the member 106. The members-105, 106 then rotate slowly together until the peg 106c clears the spring 111, the free end of which then again engages the pin 105d. During its rapid rotation, the member 105, the outside of which is formed as a cam surface, is arranged to operate, one or more times as required, a switch comprising a spring- controlled lever 117 carrying a contact 117b adapted to engage a fixed contact 118a.
