Filed: 1919-12-19
Abstract: 163,381. Hickman, K., and Imperial Trust for the Encouragement of Scientific &. Industrial Research. Dec. 19, 1919. Siphons. - A siphon adapted to maintain a constant liquid level in a receptacle is provided with an ejector or similar device worked by the main stream of liquid entering the receptacle or by a by-pass thereof. In the form shown in Fig. 1, a fall tube h with a bend j is connected to the water-supply pipe f by a tube k having a construction l, and the lower ends of the long limb a of the siphon and of the fall tube h terminate below the rim of a cup i secured to the siphon. In action, a part of the water supply to the vessel (not shown) is diverted through the tubes k, h, and produces a partial vacuum in the siphon, so that siphonic action is started, and the level of the liquid maintained at the level of the lower end of the limb b. In the form shown in Fig. 2, the action is started by an ejector n, o, through which the liquid flows into the tank, &c., by the inlet pipe f, and which continuously tends to produce a vacuum in the siphon. The level to be maintained in the tank can be varied by raising or lowering the apparatus by means of the support q.

Title: Process for the production of sulphonic acid salts
Filed: 1954-11-05
Abstract: Sulphonates are prepared by reacting a sultone with a compound containing the group <FORM:0787254/IV (b)/1> wherein Me represents a monovalent metal, the compound being one other than a metal salt of isothiourea or of a substituted isothiourea.  The reaction may be effected in the presence or absence of organic solvents or diluents, e.g. lower alcohols.  The sultones specified are those described in the parent Specification.  The other reagents may be the mono-valent metal salts of thioamides, such as thioacetanilide and dithio-oxamide, and such cyclic compounds as rhodanine.  In examples: (1) thioacetanilide is dissolved in methanolic sodium methylate and molten propane-sultone is added thereto, the reaction mixture being thereafter heated to 50-60 DEG  C. and then worked up to isolate the sulphonate C6H5-N = C(CH3)-S-CH2CH2-CH2-SO3Na; (2) rhodanine and then propanesultone are added to ethanolic sodium ethylate to yield on standing rhodanine-S-propane-o -sodium sulphonate.  In a reference to Specification 764,340, there is disclaimed the reaction of a sultone with a salt of mercaptobenzthiazole in the presence of water or an aqueous organic solvent.

Title: Process for devolatilizing polymeric materials
IPC: C08F6/28
Filed: 1964-08-07
Abstract: Molten polymers containing volatile constituents are devolatilized by feeding the molten polymer at a velocity of 0.1-15 ft./min. through a confined devolatilization zone and at a pressure of up to 200 mm. Hg applied to the exit of this zone, whereby a foam is formed containing bubbles of the volatile constituents removed from the polymer, passing the foam into a phase separation zone which is in open communication with the devolatilization zone, separating a gas phase resulting from the collapse of the foam and recovering the devolatilized polymer which has been maintained in a molten condition throughout the process.  The polymer may be polystyrene which may be modified with a rubber, e.g. rubbery styrene/butadiene copolymers, or an acrylonitrile/styrene copolymer or an acrylonitrile/butadiene/styrene terpolymer. The polymer may be fed into the devolatilization <PICT:1072624/C3/1> zone at a temperature of at least 160 DEG  C. and the gas separated may be withdrawn and recovered in a condensing zone.  The volatile constituents may comprise a mixture of styrene and ethyl benzene.  The process may be continuous.

Abstract: 686,112. Facilitating repairs to valves. YOUNG, W. E. Dec. 8, 1950 [Dec. 16, 1949], No. 32314/49. Class 135.

Title: Improvements in or relating to measuring apparatus
IPC: B21B38/00
Filed: 1963-08-15
Abstract: 1,043,169. Selective signalling. JONES & LAUGHLIN STEEL CORPORATION. Aug. 15, 1963 [Aug. 17, 1962], No. 32343/63. Heading G4H. In a system for measuring the length of a moving hot steel bar by counting clock pulses for the period between when its leading and trailing edges pass a photo-electric cell, a second cell is placed a reference distance before the first cell and the pulses which occur between when the leading edge passes the first and second cells are counted to give a count representative of the reference distance which is then divided into the count representing the length of the bar to obtain the length of the bar in terms of the reference length. As described, when the leading edge passes a first cell 32<1>, Fig. 2, a gate 241 is opened to start a count 28<1> of clock pulses from a tachogenerator driven by the conveyer rollers. When the leading edge reaches a second cell 34<1> the first count 28<1> is stopped and a second count 30<1> of clock pulses via a gate 26<1> is started. However, the first counter 28<1> is so connected to the second counter 30<1> that the effective capacity of the second counter 30<1> is determined by the count actually in the first counter 28<1> (see Specification 1,043,170, which is referred to for details). Thus the second counter 30<1> divides the clock pulses passing through gate 26<1> by the first count. The second count is terminated by the passage of the trailing edge of the bar past the second cell 34<1>, and thus the " carry " pulse from the second counter 30<1>, which are counted by a counter 64<1> represent the length of the bar in terms of the reference distance between the two cells. In a modification (Fig. 1, not shown), the second count is terminated when the trailing edge of the bar passes the first cell 32<1> (and not the second cell 34<1>). Compensation for this is effected by resetting counter 64<1> not to zero but to a count of one.
