Abstract: 328,656. Condit Electrical Manufacturing Corporation. Dec. 13, 1927, [Convention date]. Divided on 302,273, [Class 38 (v), Electric switches &c.]. Conduits and casings; insulating coverings for cables.-H.T. conductors, such as the main busbars which extend within ducts directly from generators to oil-immersed circuit-breakers controlling the branched feeders are protected from the access of conducting gases, produced during the interruption of heavy currents in the adjacent oil-immersed circuit-breakers, by being. surrounded within the ducts by a body of looselycompacted electrically insulating and fireproof particles, this body thus effectively preventing flashing-over between the conductor and its surrounding metal casing. As shown in Figs. and 2 of the bus-bars 42 are supported on insulators 60, with the metal-castings 54. The space between the bus-bars and the casing is completely filled with a body 80 of insulating material such as quartz sand the upper side of the casing being closed by a cover 58. Openings 62 may be provided in the sides of the casings, to enable branch conductors to be led into similar adjoining sand filled casings. In an alternative form (Fig. 3) the bus-bars 42, 44, 46 of a three-phase circuit are supported on insulating partitions 90, within a common duct 88 which is filled with sand in the manner described. The sand should be of sufficient fineness to prevent corona discharge in the air spaces between the particles and the conductors should be spaced sufficiently from the walls of the duct to prevent flashing over when the ducts are filled with air. In case a leakage point occurs in the duct such as at 82 in Fig. 4, only the sand immediately above this opening will escape while the remainder of the sand remains in position. Specification 302,273, [Class 38 (v), Electric switches &c.], is referred to

Filed: 1973-02-13
Abstract: 1393334 Injection moulding machines IMPERIAL CHEMICAL INDUSTRIES Ltd 11 Jan 1974 [13 Feb 1973] 7002/73 Heading B5A The invention relates to an injection moulding machine, for injecting plastics material sequentially into a mould cavity, injection of the second material commencing before completion of injection of the first material, the machine comprising two injection barrels (1, 2), a single channel 16 for connection with a sprue passage 6 of a mould cavity, ducts 14, 15 connecting each injection barrel with the single channel, means to force plastics material from each barrel into the mould cavity via said ducts, channel, and sprue passage, isolator means 9 to isolate both injection barrels from the sprue passage at the same time, and selector means having dispostions wherein each barrel in turn is connected to the single channel with the other barrel isolated therefrom, and an intermediate disposition (Fig. 3, not shown), wherein both barrels are connected to the single channel. According to the invention the selector means is located at the junction of said ducts 14, 15 and said single channel 16 and comprises a passage 20 connected to the two ducts, an opening 21 in the wall of the passage, connecting with the single channel, the width of the opening 21 being less than the width of the passage 20, and a shuttle 22 mounted in the passage 20 and movable, under the action of the pressure exerted by the plastics material, along the length of the passage, the shuttle blocking the passage, at each extremity of its movement, to prevent flow of material from the duct at that end of the passage, the shuttle at no time completely blocking the opening so that at any position of the shuttle, one or both of the ducts is connected to the opening. The shuttle is preferably a ball and the passage is of circular cross-section having the same diameter as the ball. Alternatively short cylindrical shuttles may be used or shuttles of square or other cross-section. The isolator means is a rotary tap 9 and the shuttle selector valve is located inside the spigot of the tap. The tap 9 may be rotated between on and off positions by means of a motor (8) through a squared projection 11. In operation, while injection of plastics material from the first injection barrel is continuing, the pressure on the plastics material in the second barrel is increased so as to force the shuttle in the passageway to move thereby allowing plastics material to flow from the second injection barrel into the mould cavity. While continuing injection of plastics material from the second injection barrel, injection of plastics material from the first injection barrel is stopped, thereby causing the pressure exerted on the plastics material from the second injection barrel in the passageway to force the shuttle to the other extremity of its movement. Thereafter injection of plastics material is stopped by switching the isolator means to isolate both injection barrels from the sprue passage.
