Title: A method of continuously manufacturing plastic containers
Inventor: WINSTEAD THOMAS WILLIAMSON
IPC: B29C49/36
Filed: 1957-03-18
Abstract: 821,173. Moulding hollow articles of plastic material. HEDWIN CORPORATION. March 18, 1957, No. 8778/57. Class 87(2) A method of continuously manufacturing hollow articles, e.g. bottles or containers, comprises extruding two sheets of plastic material, vacuum moulding each sheet to form half the articles and sealing the halves by pressure whilst still hot from the extrusion to form the article. Discs 14, 15, mounted on a shaft 16 rotated by a motor 21 through a belt drive 20, have fixed mould halves 22 and movable mould halves 24 respectively. The shaft 16 has a stationary internal air supply pipe 31 supplying air through a slot 34, Fig. 6, successively to air pipes 33, in a housing 32, and thence to cylinders 26 whose pistons move the mould halves 24 into contact with the halves 22. When rotation of the shaft 16 successively moves each pipe 33 away from the slot 34 air pressure in that pipe and cylinder 26 ceases and a spring, Fig. 7, (not shown) retracts the piston and mould half 24. In a similar manner the shaft 16 has a vacuum pipe 35 which via pipes 42 places the cavities of mould halves 22, 24 successively, in pairs, under vacuum. In operation, sheets 12, 13 of thermoplastic material, e.g. polyethylene, are extruded from a die 11 downwards between the resolving mould halves 22, 24, vacuum is applied simultaneously to each half drawing the sheets into the mould cavities, pressure is then applied to cause the mould half 24 to move towards the mould half 22 and to seal the sheets at the edges of the cavities, release of pressure and vacuum then enables the sheets with the formed containers to be discharged. Raised "beads" around the edges of one or both cavities applies pressure to the sheets to seal them and to form a "tear seal" enabling the containers to be readily removed from the sheets. The extruded sheet may have a varying cross section to provide optimum thickness at desired parts of the container. The two half containers may be pressed together before vacuum forming is complete and in the case of enclosed containers a temporary opening is formed in the periphery of the article to prevent partial vacuum from collapsing them.

Title: Improvements in and relating to electronic valve devices
IPC: H01J31/04
Filed: 1941-07-23
Abstract: 553,532. Cathode-ray tubes ; thermionic circuits. INTERNATIONAL TELEVISION CORPORATION, Ltd., NAGY, P., and GODDARD, M. J. July 23, 1941, No. 9309. [Classes 39 (i) and 40 (v) ] In beam deflection valves, an auxiliary electrode system is provided adjacent the target electrode O, Fig. 1, and collecting electrode E1, whereby, on the application of suitable potentials thereto, the passage of secondary electrons to and from the target electrode is controlled. As shown in Fig. 1, the auxiliary electrode system consists of an electrode E2 and a grid E3 disposed at the side of and across the electron beam in its passage to the target. The system is connected to the collecting electrode and by maintaining it at a definite potential relatively to the target, the secondary electron emission generated by the impact of the beam is either wholly suppressed or wholly transferred. Preferably the target is inclined as shown, and the beam in the form of a strip is focused to pass across the edge Z. In this arrangement, by making the secondary electron emission co-efficient greater or less than 1, the deflection sensitivity of the valve is increased or decreased by the impact of the beam on the target. Volume control may be effected by altering the focus of the beam ; this may be done by varying the potentials of the first anode A1, or the deflection plates P1, P2 or by an additional electrode E11. Where it is desired to avoid reaction between the beam and the electrode E2, the arrangement of Fig. 4 (not shown) may be used. An arrangement in which the target electrode is alternately charged positively and negatively is shown in Fig. 3. The collector electrode E1 and the target electrode O have a secondary electron emission co-efficient greater than 1. Impact of the beam on the target charges it positively by secondary emission which goes to the electrode E3. Secondary emission from the collector electrode is prevented from reaching the electrode E3 by the system E8, E7 and goes to the target, which is thus charged negatively. A simplified form of this arrangement is described with reference to Fig. 3 (not shown). The Specification describes the application of the invention to circuits for amplifying, detecting, frequency changing and oscillation generating. In the frequency changing circuit, the local oscillator may be incorporated in the electron beam valve, Fig. 6 (not shown). Specifications 366,053, 443,364, 467,573, 476,653 and 553,530 are referred to.

Abstract: 1350052 Automatic speed control MOTOREN-UND TURBINEN-UNION FRIEDRICHSHAFEN GmbH 29 Feb 1972 [2 March 1971] 9373/72 Heading G3R The speed of an I.C. engine is retroactively controlled by a system including a PID governor, a fuel injection limiting arrangement, and two speed measuring devices each capable of stopping the engine if excessive speed occurs. In the system shown in Fig.1, the speed of a diesel engine 11 is measured by a tachogenerator 12 producing a voltage proportional to speed and a digital device 13 forming a signal with a frequency related to the speed. Corresponding DC signals are fed to a selection switch 16 enabling either signal to be compared with a set speed signal from a potentiometer 17 at a junction 18. The resultant error signal passes to a PID governor 19 and then to a selection switch 22 which also receives a signal from a fuel injection governor 20. The selected output from switch 22 is compared in a gate circuit 23 with a fuel injection limit signal produced by a device 24 and dependent on engine speed, oil temperature, air temperature or air pressure. The smaller of the two signals is fed from circuit 23 through an amplifier 26 to a servo valve 27 which produces an hydraulic signal controlling a cylinder 30 associated with a fuel injection pump 31. A feedback signal from the pump is passed to a point 25 for addition to the output signal from circuit 23 and also to a proportionality adjusting circuit 35 connected to the junction 18. A stop valve 29 is actuated through an OR gate 34 to stop the engine if either of the actual speed signals exceeds a given level. An arrangement using four diesel engines to drive generators supplying a common main is described, Figs.6-7 (not shown).

Title: Improvements in and relating to engine drifting valves
IPC: F01B25/00
Filed: 1921-03-30
Abstract: 181,519. McVoy, V. P. March 30, 1921. Fluid-actuating mechanism.- Relates to an anti-vacuum valve for steam engines running without steam consisting of a controlling device opened by differential pressure and kept open by the agency of vacuum creating means. The branch 1<a> is connected to the boiler and branch 1<b> to the engine so that when the steam is turned on it will enter space 8 and pass through equaliz. ing holes 7 into the annular channel 6 and thence through the upper equalizing hole 9 into space 10. The pressure from the engine is maintained through member 4a and a vacuum channel 44 into the space below the wall 24, and also into space 31 and into chamber 42. When the throttle is closed to allow the locomotive to drift the engine pistons consume the steam in chambers 31 and that below wall 24 and thence the steam in chamber 42 presses upwards the piston 34, which carries upwards the stem 21 of the pilot valve thus uncovering ports 11 and consequently allowing the steam above the piston 5 to pass through the ports 9, annular chamber 6, ports 11, nuts 26, bore 27 and chamber 31 and out through the nozzle to the engine. This reduces the pressure above piston 5 and hence the pressure in chamber 28 raises the piston from its seat 16 so that the steam passes through space 33, ports 30, and chamber 31 out through the nozzle to the engine with sufficient velocity to produce a vacuum between nozzle portions 50 and 46 which, action through the channel 44 holds the piston 34 in its raised position, thus keeping the drifting-valve open until the locomotive stops or the throttle is opened. If the throttle is opened suddenly and shut off again so the pressure does not reach chamber 42, the engine creates a partial vacuum pulling the piston 34 upwards and the valve 39 then serves its purpose of admitting air through opening 38, space 36, chamber 40 and passage 41 into space 42 to destroy the vacuum on the under side of the piston 34. The nozzle is so arranged that during drifting steam passes to the engine at not more. than 5 lb. per square inch.
