IPC: B29C31/04
Filed: 1968-07-26
Abstract: 1,274,646. Cast in or injecting in vacuo. A. Y. STIRRAT. 24 July, 1969 [26 July, 1968], No. 35879/68. Heading B5A. In apparatus for encapsulating, impregnating, or moulding with a liquid resin gravitationally discharged or injected from a nozzle 4 sequentially into a plurality of moulds 17 located within an evacuated chamber 1, the moulds 17 are supported on a table 2 which is rotatable from a hand wheel 3 outside the chamber 1, and the nozzle 4 is mounted, via an arm 5, to a shaft 6 rotatable by a handle 9 outside the chamber 1, whereby the nozzle 4 and successive moulds 17 may be brought into alignment. Seals 18 are provided to seal the chamber 1 from the shaft 6 and hand wheel 3. The arm 5 comprises a part 5a pivoted at 20 to a projection 5b from the shaft 6 and which projection 5b, when the part 5a is pivoted in a clockwise direction, acts as a cam to pivot an arm 5c, at 21, away from the arm 5a and against a spring 25 to raise a nozzle valve 23 to permit discharge into a mould 17 of a resin supplied to the nozzle 4 at 24, by a flexible or jointed conduit 7 communicating with a container 8, at a pressure either above or below atmospheric but above that within the chamber 1. When the resin is gravitationally cast, the nozzle 4 is located above a mould 17 and the resin is discharged therefrom by pivoting the arm 5a on raising a rod 28, located within the shaft 6 and to which the arm 5a is attached by an arm 25 sealingly extending through a slot 26 in the shaft 6. When the resin is injected into a mould 17 under pressure, the nozzle is brought into sealed closing contact with the mould 17 by lowering the shaft 6, by means of a threaded engagement with a nut 11 which is urged against a support 16 by a spring loaded arm 14 and is rotated from a drive initiated by a switch 10 adjacent the handle 9. When the nozzle 4 abuts the mould, the part 5a is pivoted to open the nozzle and when the closing force overcomes the spring tension thereon, the arm 14 is raised by the nut 11 to actuate a switch 15 to halt the drive to the nut. The nozzle 4 may alternatively be urged against a mould 17 by a weight or fluid pressure. It is stated that the apparatus may be automatically controlled to apply the nozzle 4 to a mould 17 for a preset time, and thereafter lift the nozzle 4 from the mould 17.

Title: The operation of electrolytic aluminium furnaces
IPC: B23K28/00
Filed: 1968-07-26
Abstract: 1,145,820. Electro-physical measurement. SIEMENS A. G. July 26, 1968 [July 28, 1967], No. 35918/68. Heading G1N. A method of determining the operative state of an electrolytic aluminium furnace comprises altering the anode/cathode spacing by a known amount and measuring the change in anode/cathode resistance. Since the resistance of the supply lead and the anode-gas-resistance is constant during the change the result is the resistance of the melt (per unit length) which is indicative of the concentration of aluminium oxide. The result may be fed to a "computor" to automatically control the charging of the furnace to maintain optimum oxide concentration (i. e. optimum efficiency).

Title: Reference and Sensing Unit for Automatic Gas Standardizers
Inventor: KOLB WILLIAM AUSTIN
IPC: G01N21/27
Filed: 1967-08-08
Abstract: 1,188,308. Infrared gas analysis. UNITED STATES STEEL CORP. Aug. 8, 1967 [Aug. 25, 1966], No.36395/67. Heading G1A. An infrared gas analyzer is calibrated periodicallyby the use of an automatic standardizer controlling the introduction of known standardizing gases into the analyzer and including means to vary the output of the analyzer amplifier, and a reference and sensing unit provided with a source of reference voltages and a comparator to compare the analyzer amplifier output with a reference voltage. The calibration is a two-stage operation. Firstly, a timer 28 in the standardizer 26 causes opening of a valve 16 to introduce into the analyzer a "zero" gas. This has a very low known proportion of a known gas and is used to calibrate the zero reading on the analyzer indicator 4 by automatic adjustment of a potentiometer 22A. The timer 28 also energizes relay 58 to close contact 58c and connect the references source 70 across the coils 46, 48 of the comparator 42, a dual bistable magnetic amplifier. The net ampere turns in coil 44 connected to the output of the analyzer amplifier, are connected with the sum of the ampere turns in coils 46 and 48 and depending on which is greater, a relay 72 or 76 is energized, causing motor 36 to drive potentiometer 22A in such a direction as to change the analyzer amplifier output and equalize the ampere turns in coil 44 with the sum of 46 and 48. The relay 72 or 76 is then de-energized. Valve 16 is then closed and valve 12 is opened to introduce "span" gas into the analyzer. This has a known proportion of known gas very near the maximum percentage reading on the indicator and thus is used to set the maximum indication value, this time by automatic adjustment of a potentiometer 24A. The timer energizes relay 54 to cause the reference source 70 to the connected only across coil 46. As before, either relay 72 and 74 are energized this time, to cause appropriate movement of potentiometer 24A acting on the amplifier 3 to equalize the ampere turns in coil 44 with those in 46. On equalization, the relay 72 or 74 is de-energized and the timer closes valve 16 and opens 8 to introduce the gas to be analyzed.

Title: Apparatus for the automatic filling of vessels
IPC: F17C13/02
Filed: 1962-09-26
Abstract: 944,795. Filling bottles. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Sept. 26, 1962 [Sept. 28, 1961], No. 36615/62. Heading B8T. A filling apparatus, which may form part of a revolving table machine, enables a bottle 1 to be filled with a liquid, for example butane or propane, to a level determined by two members 37, 38 detecting the intensity of radiation, e.g. of neutrons, from a source 36, the member 38 controlling a main inflow valve 6 and the member 37 controlling the raising of a filling head 11 having a valve 22, 33, Fig. 2, which is automatically closed when the filling head is raised. The detectors 37, 38 give an electric signal the power of which varies with the intensity of radiation received from the source 36. As the liquid rises towards the level B in the bottle 1, the radiation received by the detector 38 is decreased until the detector 38 reverses a solenoid 40, thereby reducing the pressure in a compressed air line 42 and closing the inflow valve 6. Liquid then flows to the bottle through a channel 7 throttled at 8, so reducing the rate of filling. As the level C in the bottle is reached, the reduced radiation received by the detector 38 causes a valve 44 to be reversed thereby through a pneumatic valve 46, raising a piston 12 which is secured to the filling head 11. The flow of liquid, indicated by dotted lines in Fig. 2, is cut off automatically as a spring 19 presses the member 33 down on the seal 22 to close the valve. A roller-operated valve 50 subsequently reverses the valve 46 in preparation for the next filling cycle. In a modification, the bottle may be raised to meet the filling-head. Instead of the alternative channel 7, the valve 6 may have an opening, allowing reduced flow. The level of source 36 may be adjustable to enable bottles of different sizes to be filled. The apparatus may be operated hydraulically or electrically.
