Title: Improvements in glass bottle making machines
IPC: C03B9/14
Filed: 1937-08-27
Abstract: 506,499. Making glass bottles. DAUBENSPECK, H. C., and KITSON, T. B. Aug. 27, 1937, No. 23530. [Class 56] An automatic machine for making glass bottles comprises inverted parison and blow moulds so mounted that they close in turn on the same point on the mould table, and a suction head adapted to close the open upper end of either mould, the parisons being supported by the suction head in a stationary position relative to the mould table during the opening of the parison mould and the closing of the blow mould. The mould units are carried by an horizontal spider S, Fig. 1, which is rotated continuously about a vertical axis. Each mould unit comprises an inverted parison mould 3 the halves of which are pivoted on a vertical shaft 34, Fig. 2, and a blow mould 4, the halves of which are pivoted on a shaft 44. The unit also includes a ring mould 32, a finish ring 5, a neck pin 6, and a suction head 7 which is carried by an arm 8 pivoted to swing in a vertical plane. In operation, a charge of glass from a feeder is dropped through a funnel 9 into a closed parison mould, the funnel being oscillated about an horizontal axis so that its lower end follows the movement of the parison mould to ensure delivery of the charge into the mould. 'The glass is compacted about the neck pin 6 by suction, and the suction head 7 then descends and closes the open end of the mould, as shown in Fig. 2. The neck pin is then withdrawn from the ring mould 32 and air is admitted to blow up the glass in the mould. The air is then cut' off and suction is applied to the head 7 and the mould is opened, the inverted parison being supported by the suction applied to the head 7. The blow mould is then closed about the parison and blowing is completed. Finally, the blow mould opens and the head 7 rises and carries with it the finished bottle until the suction is released and the bottle falls into a discharge shoot 10, Fig. 4. This shoot is inclined and is closed at its lower end by a wall or stop 11. When a bottle strikes the stop, it falls backwards through an opening 12 on to a conveyer. The opening and closing of the moulds, and the vertical movement of the suction head 7 and of the neck pin 6, are controlled by stationary cams, and air is admitted to the ring by the movement of a piston valve 61 which forms the stem of the neck pin. A cam track 52 which moves the neck pin is adjustable on its support in order to adjust the period during which the pin remains in the parison. The application of vacuum to the head 7 is controlled by a valve, carried by the head. and operated by strikers 72, 71 when they make contact with the top of the mould and with an adjustable stop 85, respectively.

The fluid polychloroprene is described as one having a Mooney viscosity ML 1 + 4<SP>1</SP> (100‹ C.) below 25‹ C. The blend may be prepared by polymerizing chloroprene in aqueous emulsion to give a latex of a benzene soluble polymer having the above viscosity in the range 40 to 100 optionally in the presence of 0,1 to 1% by weight of diethyl or diisopropyl xanthogendisulphide then adding a xanthogen modifier to give an amount equivalent to 2 to 7% by weight of diethyl xanthogen disulphide relative to the amount of monomer remaining or to be added and then polymerizing this monomer to give a fluid benzene soluble polychloroprene. Alternatively as exemplified the blend may be produced by mixing a latex of a sol polychloroprene prepared using 0À3 to 0,525% by weight diethylxanthogen disulphide with a latex of a fluid polychloroprene prepared using 2-6% by weight diethylxanthogen disulphide and drying the blend. The blend may be compounded with the usual vulcanizing ingredients and vulcanized.

Abstract: 812,879. Descaling strip metal. UNITED STATES STEEL CORPORATION. July 25, 1957, No. 23645/57. Class 82(2) Ferrous strip is descaled by being first subjected while under tension to a light reduction in a coldrolling mill whereby the combined tensile and compressive forces effect an incipient fracture of the scale, and then introduced into a pickling bath. As shown, hot-rolled strip 10, is pulled from looping pit 11 through rolls 12, which remove sharp bends from the strip, and friction brake 13, by pinch rolls 14, and then travels through rolls 23, 24, which exert a backtension, enters cold-rolling mill 27, and passes through forward-tension rolls 23<SP>1</SP>, 24<SP>1</SP> and pinch rolls 14<SP>1</SP> before entering pickling tank 34. Mill 27 may effect a reduction of 2-4 per cent, and the back- and forward tensions on the strip should be equal.

Abstract: 354,063. Liquid-level pressure gauges. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Johnston, P. J. ; 2141, Plaza, Schenectady, New York, U.S.A.) Aug. 13, 1930, No. 24278. Convention date, Aug. 20, 1929. [Class 106 (ii).] Comprises means for preventing discolouration of the indicating tube in gauges of the McLeod type. One limb of the U-tube constitutes a barrel for a plunger, the other one 9 is bifurcated into a tube 12 terminating in a closed indicating tube and a tube 13 which again is bifurcated into two tubes 14, 15 which are again joined into a tube 17 leading to the chamber containing the vacuum to be measured. The normal use of the instrument is to lift the plunger in the one leg so that the mercury falls in the other leg below the join between tubes 12, 13, the tubes 12 . . 15 being all then in communication with the vacuum chamber. The plunger is then depressed and the mercury raised to cut off communication between tubes 12, 13 and to compress the residual pressure fluid on to the indicating tube 16. The difference in height between the mercury in this tube and the tube 14 is a measure of the small residual pressure in the evacuated chamber. A trap 24 is formed by a re-entrant tube 23 below the joining of tubes 12, 13 and the contaminating material which may form a vision-obstructing film on the inside of the indicating tube, is entrapped at this point which is remote from the indicating tube. The plunger barrel is provided with an overflow chamber to prevent spilling of mercury.
