Patent GB-800850-A (GB)
Title: New quaternary ammonium compounds
IPC: C11D1/62
Filed: 1956-12-24
Abstract: One or more esters of acrylic and/or methacrylic acid in monomeric, dimeric or oligomeric form are reacted with secondary bases and then quaternated, the esters used as starting materials having at least 8 carbon atoms and not having tertiary amino or quaternizable heterocyclic groupings in the alcohol residue.  Both steps are preferably carried out under pressure, and under conditions such that the product is obtained as an emulsion, e.g. by adding the quaternizing agent to a stirred aqueous emulsion of the tertiary aminoester.  The secondary base used may be aliphatic, aromatic, araliphatic or heterocyclic, the quaternizing agent being an alkyl or aralkyl halide or a dialkyl sulphate.  The products are bactericides and emulsifying agents.  In the examples: (1) hexanediol-1 : 6-dimethacrylate is reacted with dimethylamine and quaternated with methyl iodide; (2) C12- C18 alcohols methacrylate is reacted with dimethylamine and quaternated with dimethyl sulphate in an emulsion of spindle oil, or with benzyl chloride; (3) decyl methacrylate is treated with dimethylamine in the presence of catechol, and quaternated with methyl chloride; (4) decyl methacrylate is treated successively with morpholine and methyl iodide; (5) methyl methacrylate dimer is treated with dimethylamine and quaternated with dimethyl sulphate.  In all the examples the intermediate tertiary amino-ester is isolated.  Other specified reagents are diethylamine, piperidine and ethyl bromide.ALSO:Bactericidal, surface-active and emulsifying compositions contain quaternary ammonium compounds obtained by quaternating tertiary amino esters prepared by reacting secondary amines with esters of acrylic and/or methacrylic acid in monomeric, dimeric or oligomeric form; the esters used as starting materials have at least 8 carbon atoms and do not have tertiary amino (or quaternisable heterocyclic) groupings in the alcohol residue; the compositions preferably contain also about 10 per cent of the tertiary amine used in the preparation of the quaternary compounds. They may be used in emulsion form (e.g. with spindle oil in water) and in association with enzymes, particularly for cleaning surgical instruments, dairy apparatus or crockery, or the treatment of laundry linen.  Specified compounds are derived from (a) hexanediol-1 : 6 dimethacrylate, mixed C12-C18 methacrylate, decyl methacrylate or the dimer of methyl methacrylate, (b) dimethylamine, diethylamine, morpholine or piperidine, and (c) dimethyl sulphate, benzyl chloride, methyl iodide or ethyl bromide.

Title: Differential fluid-pressure actuated valve
IPC: E05F15/49
Filed: 1963-10-15
Abstract: 1,003,934. Door operating gear. H. TEVES, E. A. TEVES and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK KOMM. GES.] Oct. 15, 1963 [Oct. 17, 1962], No. 40615/63. Heading E2M. [Also in Division F2] The hollow-sliding closure-member b, Fig. 1, of a differential-pressure valve is spring urged to the position shown when lines n and o are closed; upon opening these lines pressure fluid flows to line o via an orifice i and chamber f as well as by a chamber e and an orifice c in the member b. The pressure drop across the orifices i and c cause rightward movement of the member b so that a groove d in the latter interconnects lines o and n. The member b remains in this position even if the line o is subsequently closed until such time as both lines are closed whereupon the closure member returns to the position shown. A pair of such valves is controlled by two interconnected valves 25, 25<SP>1</SP>, Fig. 2, to operate a double-acting ram 4 connected by linkage to folding doors 1. The door is opened by pressing a button 27 to open valve 25<SP>1</SP> so that fluid discharges from ram 4 to a reservoir 8 via orifices 20<SP>1</SP>, 17<SP>1</SP> of a first differential-pressure valve 11, line 36 and valve 25<SP>1</SP>; the closure member 15<SP>1</SP> therefore moves rightwardly to connect a chamber 18 directly with the reservoir 8 by a line 33. Even though button 27 is released the member 15<SP>1</SP> will remain open as long as fluid discharges from the ram. Should the door encounter an obstacle so that the ram piston is stopped the door will remain in that position and the valve will return to the position shown. A button 26 is pressed to close the door, which button opens valve 25 so that pressure fluid flows from an accumulator 7 into a line 34 via both orifices 17, 20 of a second differential valve 10; from line 34 the fluid flows through valve 25, lines 36, 37 orifice 17<SP>1</SP> and a line 35 to the ram 4. Closure member 15 is unseated by the differential pressure thereacross to open a direct path from the accumulator 7 to the ram 6 via line 30, chamber 19, orifice 17, chambers 18, 23, line 36, valve 11 and line 35. For emergency operation a valve 29 is opened so that the system pressure drops whereupon the door can be manually opened.
