Title: Fluid control valves
Inventor: GRAYSON JOHN HARRY
IPC: F16K35/14
Filed: 1957-11-28
Abstract: 835,969. Valves. GENERAL CONTROLS CO. Nov. 28, 1957, No. 37102/57. Class 135. A fluid control valve for controlling the operation of a gas-consuming water heater comprises a manually operated valve actuating mechanism which initially opens a supplementary valve to permit a supply of gas to pass to a pilot burner and subsequently opens the main valve to supply gas to the burners. The supply of gas to the burners is also regulated by a thermostatically controlled valve sensitive to the water temperature. The main valve closure member comprises a hollow cylindrical rotor unit 17 carrying a closure element or shoe 18 spring loaded into contact with the walls of the casing 12 and co-operating with an outlet port 23 to the burners. The inlet to the rotor unit 17 is controlled by a thermostat valve 43 mounted on a spindle slidable supported within the rotor unit. The thermostat comprises an outer tube 33 of metal having a high coefficient of expansion and a rod 34 of metal having a negligible coefficient of expansion. Expansion and contraction of the tube 33 causes the rod 34 to coact with the convexconcave disc 45 of a snap-acting device which actuates the valve member 43. Rotation of the rotor unit 17 causes it to move axially relative to the tube 33 thereby adjusting the setting of the thermostat for each position of the rotor unit. The rotor unit is provided with a lug 58 which co-operates with a peripheral slot 59 in a manually rotated operating member 51, which constitutes the selector knob of the valve. The slot 59 is of greater dimension than the lug to provide a lost motion connection between the rotatable member 51 and the rotor unit 17, when the slidable member 63 is withdrawn. On rotating the member 51 anti-clockwise from the " off " position a stop 74 co-operates with a rotatable lever 73 which withdraws the slidable member 63 against its spring bias. Further rotation of the member 51 causes the slidable member 63 to engage a collar 90 on the stem of a supplementary valve 87 which, when depressed, opens the valve 87 to allow gas to flow through an orifice 92 to a pilot burner. When the pilot burner has been ignited heat from the flame energizes the solenoid coil 86 which then retains the valve 87 in the fully open position, allowing gas to flow to the main rotor unit 17 via the thermostat valve 43. Continued rotation of the member 51 progressively opens the main valve, the slidable member 63 having returned to its initial position. Should the coil 86 fail to energize this will be detected by the rotatable member 51 in the " light pilot " position tending to return to the " off " position under the action of the valve spring 88, the lost motion connection with the rotor unit permitting this movement to occur.

A device for controlling the dosage of a syringe, by limiting retraction of the plunger, comprises a column 6, mounted rearwardly of the syringe and parallel to its axis, and carrying a stop member 20, which may be a nut threaded on to the column. An abutment member 8, having an extension 81 engaging around the column, is attached to the plunger 2 and limits retraction of the latter by abutting against the nut 20. In order to prevent tilting of the plunger, a spring, aligned with the plunger axis, is attached between a stirrup 18 at the top of the column and an extension 811 of the member 8, so placed that it does not prevent the user's thumb being placed against the end of the plunger. To facilitate dismantling the syringe for cleaning, the extension arm 8<SP>1</SP> engages the column 6 by a laterally open slot which is normally closed by a spring clip engaging both the arm 8<SP>1</SP> and the column 6.

Title: Preparation of film-forming emulsions
Inventor: GLABISH DIETRICH
IPC: C08F10/00
Filed: 1964-09-16
Abstract: Film-forming, stable, aqueous emulsions of copolymers of ethylene and vinyl chloride are prepared by a process in which ethylene is polymerized in a first step in aqueous emulsion under elevated pressure with vinyl chloride to form a copolymer containing 50 to 75 weight per cent of vinyl chloride and this copolymer is then further polymerized, in a second process step with 5 to 25 weight per cent of vinyl chloride in the absence of ethylene, if desired with the addition of fresh activator, until the product contains 65 to 85 weight per cent of intrapolymerized vinyl chloride.  Specified initiators are alkali metal persulphates and perborates and hydrogen peroxide, optionally with reducing agents such as sodium pyrosulphite, sodium bisulphite, sodium formaldehyde sulphoxylate and triethanolamine. Emulsifiers, e.g. fatty acid and modified rosin soaps, alkyl sulphates and sulphonates, alkaryl sulphonates, sodium dioctyl sulphosuccinate, amino alcohol esters of fatty acids, condensates of ethylene oxide with alcohols and alkyl phenols, the ammonium salt of a styrene/maleic acid copolymer and the sodium or potassium salt of a styrene sulphonic acid/maleic acid copolymer. The process may be effected batchwise or continuously, to give emulsions of high solid content suitable for coating glass, paper, leather, textiles and metals.  Minor proportions of other monomers, e.g. maleic half esters of aliphatic and cycloaliphatic alcohols or alkali metal and ammonium salts thereof, and salts of polymerizable unsaturated sulphonic acids, may also be present, when conventional emulsifiers may be omitted.  In examples, ethylene and vinyl chloride are copolymerized in aqueous media in the presence of potassium persulphate, dipotassium phosphate, and (1) sodium lauryl sulphate, (2) the amide/ammonium salt of a styrene/maleic anhydride copolymer, (3) sodium vinyl sulphonate, (4) monopropyl maleate, and (6) monoethyl maleate.
