Title: Improvements in or relating to the preparation of estrane sulfate salts
Inventor: SALKIN RALPH
IPC: C07J31/00
Filed: 1951-04-17
Abstract: The invention comprises a colourless estrane sulphate salt which is a reaction product of a hormone of the estrane series, e.g. estrone, equilin or equilenin, with a pure tertiary aminesulphur trioxide addition compound, characterized by its solid granular form and its process of preparation by mixing in a pre-cooled inert chlorinated hydrocarbon medium under anhydrous conditions and in the presence of a free tertiary amine, a hormone of the estrane series and an excess of tertiary amine-sulphur trioxide addition compound substantially free from occluded moisture and acidic substances whereby a granular reaction product is formed, separating the latter and decomposing it in an alkaline medium, removing the liberated amine from said medium, then isolating the free estrane sulphate from the medium and purifying said sulphate.  The reaction product may be reacted with an alkali carbonate salt or alkaline earth metal compound to produce the corresponding alkali and alkaline earth metal estrane sulphate salts respectively.  As the hormone there may be used estrone, equilin or equilenin.  The reaction may be effected in carbon tetrachloride as solvent and pyridine as the free tertiary amine used or alternatively picoline, dimethylaniline, N-ethylmorpholine or trimethylamine.ALSO:Stable and physiologically active compositions comprise potassium estrone sulphate in 20-50 per cent solution of lower aliphatic alcohols containing up to 3 C atoms such as ethanol, glycerine or preferably propylene glycol, in pyrogen-free distilled water.  Additionally sodium chloride may be present and a bacteriostatic agent e.g. phenol or tricresol.  Oral compositions comprise potassium estrone sulphate and a vehicle e.g. magnesium oxide.  In an example a solution is obtained by dissolving 20 mg/ml of the sulphate ester salt and 0.9 per cent of sodium chloride in a 25 per cent solution of propylene glycol in pyrogen-free distilled at pH 7-9.

Title: Improvements in windscreen wipers
IPC: B60S1/08
Filed: 1965-03-05
Abstract: 1,101,441. Control of motors. KEMPSTON ELECTRICAL CO. Ltd., and L. A. TIMBRELL. 15 March, 1966 [5 March, l965], No. 9469/65. Heading H2J. [Also in Division A4] In a windscreen wiper system having means for producing intermittent operation of a wiper motor the closing of two switches 81, S2 causes charging of a condenser C through a variable resistor R1 to render a transistor TR1 conductive and thereby energize a relay RL. Relay contacts RL1 then close to discharge the condenser through a resistor R2 so that the relay becomes de-energized and the cycle is repeated, each energization of the relay RL also closing contacts RL3 to energize the wiper motor intermittently. The circuit also includes a moisture detector D comprising interlaced metal strips (M 1 , M 2 , Fig. 2, not shown), on an insulating base (B) mounted on the vehicle exterior so that when rain water collects thereon the strips are bridged to complete a circuit through a resistor R3. This causes a second transistor TR2 to conduct to energize the relay RL. A heater H controlled by relay contacts RL2 dries the detector D sufficiently during light rain or drizzle to render the transistor TR2 inoperative. The wiper motor then operates intermittently under the control of the transistor TR1, but during heavy rain the wiper motor is operated continuously under the control of the transistor TR2 and the detector D. Preferably, a windscreen washer is brought automatically into operation when the detector D energizes the wiper motor. When switch S is open and switch S2 is closed the wiper motor is controlled only by the detector D. A further system is described in which a relay (R, Fig. 5, not shown), controlling the wiper motor is in a circuit containing three resistors, two being associated with a resistance-capacity time delay system and the other being associated with a moisture detector.

Abstract: 1453404 Contactor auxiliary interlock WESTINGHOUSE ELECTRIC CORP 7 March 1975 [14 March 1974] 9638/75 Heading H1N An auxiliary interlock for a contactor subject to vibration has a movable conductive contact carrier 44 carrying movable contact buttons 28   and resilient contacts 72, the latter being closer to the stationary contacts 30 than the contact buttons so that they will "make" first and remain resiliently pressed against the stationary contacts if the button contacts momentarily separate due to shock or excessive vibration. The resilient contacts may be of berylliumcopper alloy strip bent into a U-formation at the ends. The contact carrier 44 is mounted on an operating arm 42 which is slidable in the housing 24 and extends therethrough to provide a portion 56 for operation by the arm of the contactor (Fig. 1, not shown). In the "normally open" arrangement shown closure is effected by downward movement of rod 42, transmitted via bearing plate 50 and spring 46 which overcomes the resistance of spring 48. The assembly may be inverted to provide a "normally closed" arrangement (Fig. 3, not shown) by lodging the bearing plate 50 against shoulders 64 instead of 62 so that the spring 46 is compressed.

Title: Improvements in and relating to the oxidation of ammonium sulphite in aqueous solution
IPC: C01C1/247
Filed: 1931-03-31
Abstract: In oxidizing a solution of ammonium sulphite by means of oxygen-containing gases such as air, the solution contains a ferrous salt and free acid in quantity sufficient to keep the ferrous salt in solution, but insufficient to cause loss of sulphur dioxide, the temperature being maintained below 50 DEG  C., and preferably below 40 DEG  C.  The acidity of the solution must be within the limits defined by a pH value of 5,5-6.  The quantity of iron required need not exceed 1 part by weight per 50 parts of ammonium sulphite to be oxidized.  The ammonium sulphite solution may be produced by reacting sulphur dioxide, such as obtained from combustion gases or by burning spent oxide used in gas purification, with ammonia, for example, synthetic ammonia, or as crude ammoniacal liquor or ammonia obtained by distillation of this latter with lime.  The solution to be oxidized may contain ammonium sulphate, and the iron salt may be passed continuously into solution, as by bringing the solution into contact with scrap iron, or by effecting the reaction in an iron vessel.  The iron may be precipitated from the final solution by means of hydrogen sulphide or ammonium sulphide, and the ferrous sulphide returned directly to the oxidizing vessel wherein it is re-dissolved.  The oxidation process may be effected by passing the solution down a tower provided with baffles into which the oxygen-containing gas is passed.  The solution obtained may be concentrated by means of heated gases, and crystallized.  According to the Provisional Specification, an iron salt, preferably in the ferrous state, is employed, and no specific limitation is imposed as to the minimum pH value of the solution to be oxidized. Specifications 356,283 and 360,574 are referred to.
