Title: Improvements in and relating to moulding articles
Inventor: JAGGER ERNEST THORNTON
IPC: B29C43/18
Filed: 1961-04-24
Abstract: 1,019,082. Moulding composite articles. GEORGE ANGUS & CO. Ltd. April 18, 1962 [April 24, 19611, No. 14713/61. Heading B5A. A method of forming and conveying composite units to be moulded into articles, each unit consisting of a blank of plastic material at least partially embedding an insert to be united therewith by moulding, comprises moving a strip of plastic material longitudinally successively locating inserts in overlapping relationship with the plastic material, each insert being embedded in the plastic material by pressing them together, the plastic material being cut to form a blank with the insert embedded therein as a composite unit, and the composite units so formed being then entrained in continued movement of the plastic material remaining as a strip which serves as a conveyer for delivering the composite units for subsequent moulding. A synthetic rubber strip 2 is fed intermittently through a mechanism 5 which cuts annular blanks from the strips 2 and presses them into metal inserts 6. The mechanism 5 comprises a lower bolster 21 and an upper bolster 22 slidable vertically on guide pillars 23 and forms the head of a downwardly acting pneumatic press. Within the upper bolster 22 is a cylinder 27, and piston 30 with tubular piston-rod 31 having a ring knife 33 mounted as a sleeve at its lower end, and a stem 29 depending from the cylinder head with a cylindrical plunger knife 32 mounted on its lower end. A metal ring 6 is positioned on a tubular pommel 39 on lower bolster 21 and the strip 2 is held stationary above the ring 6 and between the two bolsters; the knife arrangements 32, 33 are brought down to cut out a ring blank and press it into the metal insert 6. A pneumatic stripper ring 40 in the lower bolster 21 and a stripper ring 35 in the upper bolster 22 permit the composite article to be retained in the strip 2.

Patent GB-514960-A (GB)
Title: Improvements in or relating to electric circuit interrupter
IPC: H01H1/50
Filed: 1938-05-19
Abstract: 514,960. Gas-blast switches; switch contacts. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. May 19, 1938, No. 14921. Convention date, May 22, 1937. [Class 38 (v)] In a circuit-interrupter having a fixed contact positioned within an elongated arc-passage and a contact-member movable longitudinally of said passage to open and closed circuit positions, the movable contact member comprises a pair of elongated blade elements a portion of which, during the final closing movement engages a stop adjacent one end of the passage to cause relative longitudinal and lateral movement of the blade elements, whereby the contact positions of the latter are actuated into high-pressure engagement with the fixed contact. The switch can open a load circuit and at the same time provides an adequate isolating gap. The fixed contact is formed as an enlargement 27 of a tube 17 which is housed in an insulator 11, formed with a weather-shield 87 and screws on to an insulating tube 15, for example of fibre. The tube 17 contains an insulating plunger 29 urged downwardly by a spring 35 and carries a cork gasket 25, threaded collars 19, 75 and line terminal 73. The other line terminal 71 is attached to a tubular contact 57 carrying a spring 83 which constantly bears on a semicircular crosssection blade 43 on a movable contact-member 41 slidable in the tube 57. A further semicircular cross-section blade 45 is mounted on blade 43 by means of the link 47 and is urged into position shown by a compression spring 77 engaging recesses 79, 81 in member 41 and blade 45. When the switch is to be closed from the open position shown, as by applying a stick to hook 65, the end 46 of blade 45 engages and raises the plunger 29 until stopped by the cap 33. Further movement of 41 causes relative longitudinal movement between 43, 45 whereby the link 47 is caused to spread them and urge their enlarged hemispherical ends against contact 27 and also their lower ends against the reduced part 55 of contact 57. The parts are frictionally retained closed against the action of gravity and spring 35. In the initial opening movement, blade 43 moves independently of 45 which is frictionally retained, but this relative movement assisted by spring 77 causes the blades to be brought together. When blade 45 begins to move downwards, the plunger 29 follows, and being of slightly smaller diameter than the tube 15, confines the arc closely between itself and the tube 15. The latter, together with the plunger, if desired, gives off an arc-quenching gas under the action of the arc, which is thus quenched by the ensuing blast. The Specification states also that overload protection may be obtained by means of a fuse, the arrangement being applicable in cases where a consumer's line is such that continuity of service is of minor importance and the load is insufficient to warrant the cost of the usual circuit-breaker and isolating switch.
