Patent GB-438515-A (GB)
Title: A method of purifying crude extracts of the germinal gland hormones and of isolating the latter therefrom
IPC: A61K31/56
Filed: 1934-05-07
Abstract: Germinal gland hormones are isolated from extracts containing them by treating said extracts with acylating agents under anhydrous conditions, separating the esterified products from the non-esterified parts by physical methods, saponifying the purified esters and isolating the hormones.  The process is applied particularly to the purification of male hormone and to the separation of mixtures of various hormones and like substances such as pregnandiol.  The physical methods used for isolating the esterified hormones include fractional crystallization from dilute alcohol or dilute acetone, fractional distillation in very high vacuum, and extraction with pure organic solvents such as alcohol, ethyl acetate or acetone.  Acylating agents referred to are acetic anhydride, phthalic anhydride, p-toluene sulphonic acid chloride, anthraquinone-2-carboxylic acid chloride and salicylic acid chloride. When acid chlorides are used the reaction may take place in presence of an agent such as pyridin serving to combine with the hydrochloric acid produced.  The hormone-containing extracts employed may be prepared from urine or from organs, and may be crude or may have been pre-treated by known purifying processes.  According to examples: (1) an extract from male urine is treated with toluene sulphochloride in solution in toluene containing also pyridin, the precipitated pyridin hydrochloride is removed and the esterified products separated and saponified; (2) an extract from the urine of pregnant women is acylated as in (1) and a fraction obtained by distillation is saponified, the saponification solution is largely diluted and extracted with ether, the ethereal extract is shaken with concentrated alkali hydroxide to remove follicle hormone and is then concentrated by evaporation so that pregnandiol separates in crystals and the male hormone remains as an oily residue; follicle hormone hydrate remaining in the saponification liquid when the latter is extracted by ether is recovered by neutralizing with CO2 and extraction with ether.  Specifications 432,435, 432,474, and 432,851 are referred to.  Reference has been directed by the Comptroller to Specification 391,686.ALSO:A product obtained by acylating an extract of urine and separating the esters produced from non-esterified products is treated to obtain the individual hormones by a process comprising saponification by means of alkali, extraction of the diluted alkaline solution with ether, shaking the ethereal extract with concentrated alkali hydroxide solution to extract follicle hormone, concentrating the remaining ethereal extract to cause separation of pregnandiol crystals and finally to leave the male hormone as an oily residue, and recovery of follicle hormone hydrate from the initial alkaline saponification liquid by neutralization with carbon dioxide and extraction with ether. Specifications 432,435, 432,474, and 432,851 are referred to.  Reference has been directed by the Comptroller to Specification 391,686.

Title: Gas control unit for a burner

Filed: 1976-04-06
Abstract: 1534728 Valves SATCHWELL SUNVIC Ltd 30 March 1977 [6 April 1976] 13940/76 Heading F2V [Also in Division F4] A gas control device for a burner comprises a first main valve 16 and a second main valve 15 movable together so that when a closed first chamber 11 is segregated, a second chamber 12, which is closed when the main valves are open but which communicates with chamber 11 by an auxiliary valve 26 which opens when the main valves are closed and vice versa, and a shut-off valve 22 normally open but responsive to gas pressure in chamber 12, so that on leakage past valve 16 when supposedly closed, orifice 20 in the gas flow is closed, and due to closure of chamber 12 by valve 26, the gas flow path is maintained closed when valves 15, 16 are subsequently opened. In operation, a solenoid 25 is energized to thus open valves 15, 16, to supply gas to a chamber 5 and close valve 26. The pressure in chamber 5 urges diaphragm 27 upwardly to left valve spindles 23 until a flange 31 abuts a bimetallic strip 30, and a restricted gas flow passes through orifices 20, 6 to be ignited by a spark igniter. A signal from the flame detector energizes a coil 34, which heats strip 30 so that its downward deflection opens valve 21 to provide full gas flow, and at the end of the operation solenoid 25 is de-energized and valves 15, 16 close. If gas leaks past the closed valve 16 it passes via valve 26 and orifice 3 into chamber 14, to thus close shut-off valve 22. A microswitch 36 prevents operation of the controls unless spindle 23 has been raised by the gas pressure in chamber 5.

Abstract: 730,694. Erecting buildings. ROBERTS CONSTRUCTION CO., Ltd., and DAWSON, S. E. May 18, 1953 [May 23, 1952], No. 13959/53. Class 20 (1). A method of erecting buildings comprises casting successive horizontally superimposed layers of wall panels 5 of a cementitious material e.g. reinforced air-entrained concrete, e.g. 2 to 3 inches thick, on a cast floor 11 by means of a surround shuttering 4 which is raised vertically to accommodate successive layers, the panels being thereafter lifted separately to their final positions. Roof panels 14 may be included. Superimposed panels are arranged so that openings, e.g. for doors or windows, are positioned on top of each other in vertically adjacent panels, the opening in the upper of such panels being at least equal in area to the opening beneath it. Strips 18, 19 enable panels of various shapes to be formed, e.g. to allow for a pitched roof, and for slots to be formed in panel edges to accommodate rafters. Flush loops are cast in the panels and bent up when the panels are to be raised, e.g. by a crane. The building is erected by levelling the ground and casting concrete piles 3, a trench 8 being cut, its outside wall coinciding with the outer edge of the piles 3 to take a plinth surround 7. The shuttering 4 with jacks 9 is then positioned and levelled, and earth rammed inside the shuttering to effect a final levelling. The shuttering 4 is then raised, a plinth surround shuttering 10 being temporarily positioned as indicated. Concrete is led beneath the shuttering 4, the shuttering 4 and shuttering 10 determining the depths respectively of the floor 11 and plinth 7. The shuttering 4 is raised, and the panels 5, 14 cast, a breaking joint being arranged between adjacent layers. On completion, the shuttering 4 is removed, the roof panels 14 taken aside, and the walls 5 erected on plinth 7, vertical columns being cast in situ between adjacent panels 5. Roof rafters and panels 14 complete the structure. If desired, the step of forming a plinth 7 may be dispensed with, and the roof may be formed of corrugated iron. The method is applicable to cavity walled buildings.
