Title: Improvements in and relating to the treatment of waste sulphite pulp liquors
Inventor: ALDRED FRED CROWTHER
IPC: D21C11/00
Filed: 1953-09-11
Abstract: <PICT:0750347/III/1> Waste sodium sulphite pulp liquor is evaporated and burnt to remove organic constituents and leave a sulphide/carbonate residue which is dissolved in water and the solution treated at 70-100 DEG C. with sulphur dioxide, either the sulphuric dioxide passing upwardly through a coherent downwardly flowing body of liquid, or the liquid passing in divided form through an upwardly flowing body of sulphur dioxide, the hydrogen sulphide thus formed being removed continuously.  In the Figure accompanying the Provisional Specification, waste sodium sulphite liquor enters an evaporator 2, passes to a furnace 3, and thence passes in molten state to a dissolver 4, where it is preferred to use sufficient water to give the required sodium concentration in the final liquor.  The solution is sprayed into a tower 11 into which sulphur dioxide is being passed, and the solution of sodium bisulphite collected in the storage tank 15.  Hot gases from the furnace are utilized in evaporator 2 and sulphur dioxide separated therefrom by means of water in scrubbing tower 6.  The sulphur dioxide solution passes to a stripper 9 and the gas is then passed into the lower part of the tower 11.  Hydrogen sulphide produced is conducted to a burner 13 and the products added to the main sulphur dioxide supply.  In the example a mixture of 20 per cent of sulphur dioxide and 80 per cent of nitrogen by volume was passed through a downwardly moving body of solution in a glass tower, both reactants being preheated to 100 DEG C.; the minimum of sulphur dioxide for complete reaction to form sodium bisulphite was used.  Specification 376,654 is referred to.

Title: Method for parting-off a length from metal bar stock
Inventor: BAYLISS ERNEST GEORGE
IPC: B23D31/00
Filed: 1961-07-13
Abstract: 934,642. Breaking. FORGINGS & PRESSWORK Ltd. July 10, 1962 [July 13, 1961; June 23, 1962], Nos. 25359/61 and 24249/62. Class 83 (4). A method of parting-off a length from metal bar stock includes providing a sharp notch to weaken the bar in the position in which it is to be parted, and applying alternating stresses to induce rapid fatigue failure of the bar at the weakened section. In an example, a mild steel bar of 0.682 inch diameter provided with a circumferential V-notch 0.043 inch deep was gripped at one side of the notch by a stationary jaw and at the other side by a jaw capable of minute reciprocation in the direction of the axis of the bar. A basic tensile stress of 3.4 tons per square inch was applied to the bar through the jaws and an alternating stress of 13 tons per square inch was superimposed at a frequency of 40 cycles per second while the temperature of the bar in the zone of the notch was maintained at minus 60 C. The bar fractured after 41,900 stress reversals. The temperature applied to the stock may be progressively lowered with the development of the fracture. The alternating stress can be tensile, compressive, torsional, shear or bending stress or a combination thereof and applied mechanically, electrically, hydraulically or pneumatically. Any basic pre-stress may be of the same character as the alternating stress or different therefrom. The notch may be formed by mechanical working or cutting.

Abstract: 994,781. Latches. STRATTWELL DEVELOPMENT Ltd. July 11, 1962 [July 14, 1961], No. 25587/61. Heading E2A. [Also in Divisions A4 and B8] A dispenser for liquid soap comprises a rigid casing 1, secured to a wall &c. 6, and an axially collapsible container 2 provided with an ejector nozzle 14 and held within the casing so that a hand of the user can exert pressure on the nozzle to cause axial collapse of the container and at the same time receive soap ejected from the nozzle by the axial collapse. As shown, the cylindrical casing is of a hard plastic e.g. polystyrene and is secured to the wall by screwing home a screw 8 after engagement of a permanently fixed screw 7 in a keyhole slot 9, the cylindrical container 2 which is blow moulded in resiliently flexible plastic being inserted in the casing from the open end 5 and abutting a projection 15 which causes collapse of the bellows 3 when the nozzle is pressed. The amount of soap ejected is controlled by abutment of a rim 27 with a step 4 formed on the casing or with spacers fitted in the casing and allowing adjustment of the quantity ejected. The container is held detachably in the casing by engagement of a shoulder 13 with the arcuate upturned end 26 of a lock plate 20 which is carried by a leafspring 17 and is urged thereby to slide between pairs of guideplates 21, 22 to locking position, release being effected by insertion and rotation in a keyhole in the casing of a key 24 having a release member 23 which engages a downwardly projecting toe 23a of the plate 20 for retraction thereof.

Title: Improvements in and relating to the purification of penicillin
IPC: C07D499/18
Filed: 1946-08-27
Abstract: In the recovery and purification of penicillin contained in a hydrophobic organic solvent, i.e. an organic solvent for penicillin which is insoluble or substantially insoluble in water such as a hydrocarbon, chlorinated hydrocarbon, ether, ester, higher alcohol or higher ketone, the penicillin is extracted from solution with a hydrophilic solvent, which is substantially immiscible with the said hydrophobic solvent and Which is an ether alcohol or polyhydric alcoho containing not more than 3 hydroxyl groups.  In place of the hydrophilic solvent an aqueous solution thereof may be used. Suitably, the extraction is carried out using 50-90 per cent aqueous ethylene glycol or diethylene glycol at a pH of 4-7 and the resulting solution of penicillin in aqueous ethylene or diethylene glycol is diluted with water to a 10-40 per cent concentration of hydrophilic solvent and is re-extracted with a hydrophobic solvent at a pH of 1-5.  In examples (1) and (2) penicillin in ether is extracted with 80 per cent aqueous glycol and the glycol solution is acidified, diluted and extracted with chloroform; (3) diethylene glycol is used in place of glycol in the process of (1); and (4) an amyl acetate extract of penicillin is treated as in (1).
