Patent GB-662272-A (GB)
Title: Process for debenzylation of thiophane derivatives
Filed: 1949-06-08
Abstract: N - Benzylated - 3,4 - (21 - keto - imidazolido)-thiophane derivatives are de-benzylated by treatment with a hydrohalic acid or anhydrous aluminium chloride. Thiophane derivatives specified are those having the general formula <FORM:0662272/IV (b)/1> or <FORM:0662272/IV (b)/2> where R is hydrogen or benzyl, at least one in each formula being benzyl, Y is an o -substituted alkyl radical such as an alkoxyalkyl, cyanoalkyl, carboxyalkyl or a malonyl ester radical and Z is an anion.  During the debenzylation, some of the original thiophane derivative may be split to the corresponding 3,4-diamino-thiophane, but this may be reconverted to the imidazolido-thiophane by treatment with phospgene.  When the o -substituent is reactive to hydroholic acid it may be simultaneously converted.  For example, if it is an alkoxy radical it is converted to a halogen radical.  In examples: (1) 3,4-(N - monobenzyl - 21 - keto - imidazolido) - 2-(o -ethoxybutyl)-thiophane is heated with concentrated hydrochloric acid and acetic acid to give 3,4-(21-keto-imidazolido)-2-(o -chlorobutyl) - thiophane; (2) 3,4 - (11,31 - dibenzyl-21 - keto - imidazolido) - 1,2 - trimethylenethiophanium bromide is refluxed with hydrobromic acid to yield 3,4-(21-keto-imidazolido)-1,2 - trimethylene - thiophanium bromide; (3) 3,4 - (11,31 - dibenzyl - 21 - keto - imidazolido) - 2 - (o  - ethoxypropyl) - thiophane is refluxed with hydrobromic acid to give 3,4-(21 - keto - imidazolido) - 1,2 - trimethylenethiophanium bromide; (4) crude l-dibenzylbiotin is refluxed with hydrobromic acid to give d-biotin, d-monobenzyl-biotin and some 3,4-diamino - 2 - (o - carboxybutyl) - thiophane; the mono-benzyl-biotin is again debenylated and the 3,4-diamino compound is recovered by treatment with phosgene and alkali; crude l-dibenzyl-biotin is heated with hydriodic acid to yield d-biotin and d-monobenzyl-biotin; crude l-dibenzyl-biotin is heated with anhydrous aluminium chloride and chloroform to give d-biotin; (5) l-3,4-(11,31-dibenzyl-21-keto imidazolido) - 2 - (o ,o  - dicarbethoxybutyl)-thiophane is heated with hydrobromic acid to give d-monobenzyl-biotin which is again de-benzylated to obtain d-biotin; and (6) d,l-monobenzyl-biotin, acetic acid and hydrochloric acid are heated to give d,l-cis-3,4-diamino - 2 - (o  - carboxybutyl) - thiophane which is then reacted with phosgene in the presence of sodium carbonate to yield d,l-biotin.

Title: Improvement in automatic control for waste heat utilizers
IPC: F22B1/18
Filed: 1946-06-15
Abstract: 593,858. Waste heat steam boilers. TRIGGS, W. W. (Maxim Silencer Co.). June 15, 1945, No. 15304. [Class 123 (ii)] A waste heat boiler utilising the exhaust gases of internal combustion engines having automatic control of the quantity of steam generated, comprises a boiler 1, chamber 15, and pressure reducing valve 16. Exhaust gases pass through inlet 13 and chamber 7 into chamber 9 via connecting passages 11, Fig. 2. Water circulates into the compartment 4 formed between concentric drums 2, 3 from inlet pipe 5, and steam is delivered to chamber 15 via outlet pipe 6 and reducing valve 16. When steam taken from supply 17 is reduced, the increasing pressure (or temperature) in 15 operates a suitably responsive device 24 to close valve 16. Increasing pressure built up in.boiler 4 consequent on closure of valve 16 forces the water in the boiler back into inlet pipe 5 until the entire heating surface is exposed and further steam generation prevented. When steam is again taken from outlet 17 the reduction of pressure in chamber 15 operates to open valve 16 thereby reducing the pressure in the boiler and admitting water via inlet 5 until the water level in chamber 15 returns to its normal operating level indicated by line A.A. Reduction of superheat may be effected by discharging steam from valve 16 under the water level AA by extending the outlet of pipe 14 in chamber 15. Various alternative arrangements are described. Specification 582,399 is referred to.

Abstract: 1350701 Fluid-pressure servomotor systems; fluid regulation COMPAGNIE DES COMPTEURS 14 May 1971 [14 May 1970] 15339/71 Addition to 1348992 Headings G3H and G3P A flexible metallic blade 1 anchored at one end and carrying a receiver 4 proximate its other end, has its other end bent into a U-shaped configuration 16 which acts in the manner of a magnetic mass. The magnetic mass is responsive to movements of a magnet 15 carried at one end of a lever 13 pivoted at 14, the other end of the lever being subjected to a variable force F. The magnet 15 and magnetic mass 16 are separated by a non- magnetic, fluid-tight wall 12. Pivoting movement of lever 13 about pivot 14 consequent to the application of force F, results in a tilting movement of the metallic blade 1. In consequence, the resistance offered by receiver 4 to a jet issuing from a nozzle 5 varies with such variation being utilized both as an output signal at line 8 and as a negative feedback signal applied to the blade 1 through an amplifier 9 and a further nozzle 10.

Abstract: 476,486. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 2, 1936, No. 15398. Convention date, May 31, 1935. [Class 40 (v)] The selectivity of a tuned circuit is varied by variation of the mutual conductance of a pentode valve connected in shunt therewith, a portion of the signal voltage across the tuned circuit being applied to the grid of the valve to produce an opposing voltage. As shown, the tuned primary 41, 43 of an I.F. transformer 21 coupling valves 11, 19 is shunted by the anodecathode path of a pentode 47, to the grid 56 of which is applied signal voltages from the high potential end of the circuit 41, 43 through condenser 81. The steady potential of the grid 56 is controlled through resistance 59 either by manual adjustment of the slider 71 on potential divider 29 or automatically in accordance with signal strength by an A.V.C. voltage from terminal 65. The transformer 21 is so designed that an increase in the damping of the primary 41 results in an overall increase of selectivity of the transformer. In a second embodiment, Fig. 2 (not shown), the controlled circuit is an aerial circuit and selectivity is reduced when the grid of the control valve is made more positive.

Title: The use of polymeric materials in the preparation of polyurethanes and the resulting polyurethanes
Inventor: GARNETT EDWARD DEREK
IPC: C08G18/50
Filed: 1961-04-28
Abstract: A polyurethane plastic is obtained by reacting with an organic polyisocyanate or polyisothiocyanate a polymeric material comprising an addition product of a halo-epoxy-substituted alkane and a nucleating agent consisting of a compound having in its molecular structure at least three active hydrogen atoms present or thiol or hydroxyl groups. The epoxy alkane may be epichlorhydrin, epibromhydrin, 1,4,dichloro 2,3 epoxy butane or 1 chloro 2,3-epoxy pentane; and an alkylene oxide such as styrene oxide, ethylene oxide, 1, 2 propylene oxide or 1, 2 butylene oxide may also be added.  The preferred nucleating agents are glycerol, pentaerythritol, and sorbitol; though alpha alkyl glycerols, 1,2,5, pentanetriol, 1,2,6 hexanetriol, pentaglycerol, erythritol, pentitols or henitols may also be used. Specified catalysts are the etherate of boron trifluoride, sulphuric acid, phosphoric acid, stannic chloride, aluminium trichloride, titanium tetrachloride and the Lewis acids. The polyurethane prepolymers which contain free isocyanate or isothiocyanate radicals can be connected into the plastics by reaction with a difunctional group which may be water, glycols, diamines, dicarboxylic acids, hydroxyamines, hydroxy acids and amino acids.  The resulting plastic material may be foamed using tertiary organic bases such as trimethyl-amine, N-alkylmorpholine, triethylene diamine, triethylamine, tripropylamine, tributylamine, triamylamine, tribenzylamine or dimethylaniline as catalyst.  In a typical example a polymer was prepared by reacting epibromhydrin, propylene oxide, and glycerol in the presence of boron trifluoride, and this was foamed using water, triethylene diamine, silicone oil, and diphenyl methane diisocyanate.  Foaming may also be effected by using difluoro-dichloro-methane or by blowing with carbon dioxide. When non-foamed polyurethane plastics are manufactured the prepolymer can be prepared in the presence of an organic solvent which may be benzene, toluene, xylene, solvent naphtha, gasoline, carbon tetrachloride, ethyl acetate or amyl acetate.  Specification 868,996 is referred to.
