Title: Improvements in and relating to the determination, recording or control of impurities, especially oxygen, in industrial gases, or in liquids
Inventor: CAVANAGH JOHN GEORGE
IPC: G01N27/00
Filed: 1950-02-24
Abstract: <PICT:0690701/III/1> The amount of a component of a gas mixture is automatically determined and recorded by feeding an electrolyte solution, capable of absorbing and reacting with the component, at constant head through a special orifice in vessel 1, via cooling zone 2, to conductivity cell 3, mixing it (e.g. in coils 6 61) with the gas to be tested, leading the solution via a second cooling zone 12 to second conductivity cell 13 connected in a Wheatstone network with the other cell, and using the electromotive force developed across the bridge (or the change in resistance necessary to balance the bridge) to record the amount of the component present.  The special orifice is circular, and has frusto-conical convergent inlet and divergent outlet ducts, and a knife edge of thickness not exceeding 5/1000 inch.  The cross-section of the cooling zones and conductivity cells has a breadth: length ratio of not more than 1 : 3, and preferably 1 : 5 to 1 : 10.  Gas is fed to the apparatus at constant rate from inlet 7 via capillary flowmeter 8 and capillary tubes 11, 111 to the coils.  In one form of electrical circuit Fig. 2. (not shown), the two cells are in parallel in the Wheatstone network, the other arm including standard and variable resistances; output from the bridge passes through a rectifier to a recording ammeter.  In an alternative arrangement, Fig. 5, (not shown), the cells are in series, the resistance of both arms of the bridge may be varied, and the bridge system is connected to a self-balancing recorder, which may be of the electronic type.  A mechanical valve controlling the supply of the component to the gas mixture may be operated by the output from the bridge through a relay.  In the determination of oxygen, e.g. in commercial carbon dioxide, an aqueous solution of chromous sulphate containing hydrochloric acid is preferably used as the electrolyte; also suitable are solutions of vanadium, cobalt, and molybdenum sulphates.  The chromous sulphate solution may be prepared by reacting sulphuric acid in an inert atmosphere with metallic chromium and a small piece of a more electropositive metal, e.g. zinc or aluminium; the solution is filtered, diluted, and stored under carbon dioxide.  Carbon dioxide may be determined in gas mixtures using aqueous caustic potash, sulphur dioxide using a solution of bromine and sulphuric acid, and carbon monoxide by preliminary oxidation to carbon dioxide; other gaseous components which may be measured are hydrogen sulphide and ammonia.  The oxyenf content of boiler feed water may be measured by expelling oxygen from the water, and mixing it with an inert gas.  Specification 641,978 is referred to.

Abstract: 1, 113, 893. Electric control systems. SQUARE D CO. Feb. 4, 1966 [Feb. 23, 1965], No. 4936 / 66. Heading G1N. In a positioning system for e. g. a machine tool, in which an A. C. error signal of reversible phase and of amplitude proportional to displacement of the machine part from a null position is rectified to provide a D. C. signal of reversible polarity and variable amplitude, and in which this D. C. signal is amplified and applied to a reversible motor to position the machine part so that the speed of the motor is proportional to the amplitude of the error signal, the motor speed is limited to a preset value by limiting the amplitude of the error signal. A part of the D. C. error signal from position transducer 10 is tapped off a potential divider 18, 30, 20 and applied to the servoamplifier 14. Resistor 20 is large in comparison to the others and with resistor 30 is shunted by one diagonal of a diode bridge 25 biased by the velocity limiting signal source 12 connected across the other diagonal. The source 12 may be partly off-set by a further bias source 22 to allow for the voltage drop across the diodes when they conduct due to the error signal exceeding the velocity limiting signal. In a modification, Fig. 2 (not shown) the diode bridge is replaced by a single diode for use with an error signal of unchanging polarity.

Abstract: 983,440. Blow-moulding apparatus. H. V. SMITH. Jan. 30, 1964 [Feb. 7, 1963], No. 4969/63. Heading B5A. A thermoplastics blow-moulding apparatus, primarily for vinyl resins, contains a reciprocable extrusion screw 8, mounted vertically above a die 19 from which the material is discharged into a blow mould 22, a driving motor 9, coupled to hydraulic pistons 10, 11 providing means for advancing the screw 8 to perform an extrusion stroke, and retracting and rotating it to recharge the extrusion barrel 5. The screw 8 may or may not rotate during the extrusion stroke. The material used for making bottles is fed from hopper 1 by feed-screw 2 driven by motor 3, during the recharging period to the top of the barrel 5, the reciprocation of the screw 8 in the barrel 5 working the material to help keep it plastic. Additional heating means 21 are also provided. In a modification a single piston working in a double-acting cylinder is used to reciprocate the screw 8, whilst a sliding coupling may be used to prevent the electric or hydraulic motor 1 reciprocating with the screw 8 due to the action of the pistons in the cylinders. The core 8 of the screw 6 increases in diameter towards the die to help compress the material. Limit switches 14, 15 control the stroke of the screw 6. Pistons in double-acting cylinders control the movement of the mould.

Title: Hydraulically retarded door closer
Inventor: MILLARD GEORGE ROBERT
IPC: E05F3/10
Filed: 1963-02-07
Abstract: 978,966. Dashpots. RONAN & KUNZL Inc. Feb. 7, 1963, No. 5087/63. Heading F2S. [Also in Division E2] In a door-closer comprising a cylinder 3 containing a piston rod 4 carrying a piston 11 and biased towards a retracted position by a closing spring 12, a non-return valve is provided through the piston, and the fluid return passage includes a hollow needle valve 14 slidably mounted in a bore 29 in the cylinder end and biased outwardly of the bore by a spring 35, the rod being arranged to co-operate with the needle valve as the piston approaches its fully retracted position to restrict the passage through the valve. Alternatively, the valve may be mounted in the piston rod and co-operate with the end of the cylinder. The restricted passage is provided by a small notch 38 in the tapered end 37 of the valve which is adapted to mate with a chamber 28 in the end of the rod, and a second notch 33 is cut in the end of the bore 29 to provide a restricted passage past the valve when the latter is fully extended. As the valve is pushed into the bore 29 by the rod the notch 33 is closed by an enlarged portion 34 of the valve in sealing engagement with the walls of the bore, thereby providing a further reduction in the rate of fluid return. The return passage includes a bore 30 leading via an adjustable valve 15 to a return pipe 17. The piston is coupled to the piston rod by a pin 21 received in an oversized bore 22 so that the piston can slide axially to a limited extent relative to the rod, and the reduced diameter end 20 of the rod is formed with a flat portion 23 (not shown) providing a passage right through the piston. When the piston rod moves outwardly this passage opens to permit a free flow of fluid from right to left, but during the checking stroke the fluid pressure forces the piston against a shoulder 24 on the rod so that the passage is closed. A cylindrical wire filter scresn 26 is provided.

Spray, blowpipe, and pluverulent fuel burners -Relates to a burner for use with liquid and gaseous fuels either separately, together, or in conjunction with pulverized fuel. A wedgeshaped nozzle 4 connected to a compressed air supply pipe is arranged within a casing 1. Gas may be admitted through openings 2 and liquid fuel through an opening 17 to the chamber 3 on the casing 1. The compressed air escaping from the nozzle induces a flow of fuel from two outlets 6 between the nozzle and casing and of secondary air through two openings 15, 15<1>. The opening 15 is extended to form a tube 21 through which pulverized solid fuel may be introduced. The escape of compressed air is regulated by means of resilient strips 8, 9, carried by a support 10 and displaceable by means of a cam 11. The cam may be fitted with a projecting-blade so that the strip 8 may be moved to close the upper channel between the support 10 and the nozzle while leaving the lower channel open.
