Title: Fixing device
IPC: F16B21/02
Filed: 1974-05-02
Abstract: 1423478 Stud and socket fastenings A RAYMOND 2 May 1974 [11 May 1973] 19394/74 Heading E2B A device for securing a part 15 to a carrier member 17 comprises a spring clip 6 having two legs 7, 8 connected together at one end and resiliently urged apart, and a disc 1 having an aperture, through which the legs extend, and an abutment 3, 4 located over and beyond the central zone of the aperture to limit movement of the interconnected ends of the legs towards each other. The clip is firstly assembled with the disc by passing the shoulders 9, 9' through a slot 16 in the part 15 and then rotating the clip and disc through an angle of 90‹; the clip is then inserted into the hole 18 in the member 17.
Patent GB-713386-A (GB)
Title: Production of cellulose derivatives
IPC: C08B15/06
Filed: 1952-07-31
Abstract: A cellulose derivative containing morpholinyl groups is obtained by heating an acid sulphate of cellulose or of an organic derivative of cellulose with morpholine.  Acid sulphates of cellulose acetate, propionate, butyrate, acetopropionate, aceto-butyrate, glycollate and benzoate may be reacted with the morpholine.  The cellulosic acid sulphate used preferably contains 0.15 to 0.6 acid sulphate groups for each anhydro-glucose unit. In carrying out the reaction, the cellulosic acid sulphate may be dissolved in a basic solvent such as pyridine, picoline or quinoline, or even morpholine itself.  The amount of morpholine is preferably 2-7 times the equivalent of the acid sulphate groups in the cellulosic acid sulphate, one molecule of morpholine being equivalent to one acid sulphate group.  The reaction may be effected by heating the mixture to 50-100 DEG C. for 1-6 hours.  The product may be precipitated from the solution by addition of a non-solvent.  Most of the acid sulphate groups appear to be replaced by morpholinyl groups to give a structure in which the morpholine nitrogen is linked directly to the cellulose molecule, but part of the morpholine may react with the acid sulphate groups on the cellulose molecule to give a quaternary morpholinonium salt.  When an acid sulphate of a cellulose organic ester is to be used, it may be made by treating cellulose with an esterification mixture comprising the anhydride of the esterifying organic acid, sulphuric acid, and benzene as a non-solvent reaction medium.  In an example, a cellulose acetate sulphate, containing 2.42 acetyl groups and 0.58 acid sulphate groups per anhydroglucose unit, is washed with dry benzene until free from glacial acetic acid and sulphuric acid.  A solution of morpholine in pyridine is added to the benzene-wet cellulose ester and the mixture is heated to 60-70 DEG C. for 4 hours, a clear dope being produced.  An excess of ethanol is added and then diethyl ether is added to precipitate morpholinyl cellulose acetate having a sulphur content of 2.0 per cent., nitrogen 2.2. per cent., and acetyl value (calculated as acetic acid) 52.2 per cent.  Specification 677,459 is referred to.

Abstract: 296,177. Clama, A. July 25, 1927. Extincteurs; portable pressure reservoirs.-In a fire-extinguisher wherein a hollow plunger serves as a ventng means and is held against withdrawal when it has been forced in to break the usual frangible vessel of acid or compressed gas, the head 10 of the plunger 7 is guided by a sleeve 11 which is provided with an internal shoulder to limit upward movement of the plunger, and with oppositely disposed spring tongues 13, 14 at its lower end. The tongues yield when the plunger is forced in, but prevent the plunger from rising again, so that the venting passage 19, 18, 17 is sealed. The sleeve 11 is screwed into the cap 3 of the extinguisher, and the plunger 7 is surrounded by a packing ring 22 of U-shape and having a tapered inner portion 23. In a modification, the head 10 of the plunger is formed with cut-away portions which, by rotating the plunger, may be made to coincide with the spring tongues of the sleeve 11, so that the head may be withdrawn into the sleeve after the extinguisher has been used. In this modification, the packing ring has a flange which is gripped between two washers around the plunger, and the head is bored with a venting hole communicating with the hollow plunger.

Title: Manufacture of phenolic compounds containing a chloromethyl group and nitrogen-containing condensation products therefrom
IPC: C08G8/28
Filed: 1936-07-16
Abstract: Phenols substituted in the nucleus by one or more aliphatic hydrocarbon chains of at least four carbon atoms are converted into chloromethyl derivatives by reaction with a solution of formaldehyde saturated with hydrogen chloride.  The chloromethyl compounds may then be condensed with primary, secondary or tertiary amines, which may contain acidic groups, particularly sulphonic groups.  The chloromethyl compounds are useful as intermediates for textile adjuvants, dyes, synthetic resins and tanning agents.  The condensation products of the chloromethyl compounds with amines are useful as assistants in dyeing and as fungicides and insecticides. In the examples: (1) isobutylphenol is treated with a paraformaldehyde solution saturated with hydrogen chloride, and the chloromethyl compound so obtained is treated with pyridine; (2) dodecylphenol is converted as in example 1 into a chloromethyl derivative, and the latter is treated with pyridine; (3) isooctylphenol is converted as in example 1 into a chloromethyl derivative, and the latter is treated with pyridine; (4) chloromethyldodecylphenol is treated with triethylamine; (5) diisooctylphenol is converted as in example 1 into a chloromethyl derivative, and the latter is treated with pyridine; (6) chloromethyldodecylphenol is treated with methylaniline or (example 7) with aniline; (8) chloromethylisooctylphenol is condensed with sodium sulphanilate; (9) a mixture of isododecyl-, isotridecyl- and isotetradecyl-phenols is converted as in example 1 into a mixture of chloromethyl derivatives, and the latter is treated with pyridine, quinoline, trimethylamine or dimethylaniline.

Class 75(1) Control apparatus comprises a thermoelectric generator, a power circuit of low resistance and a control circuit of high resistance, a control device in the control circuit being adapted to be energized by the thermo-electric generator to cause a major portion of the output of the generator to flow through the power circuit. A pilot burner 16 heats the hot junction 6 of a thermocouple 3 to energize a control circuit inclinding a remote thermostat switch 12 and the coil 10a of a relay. The relay closes contacts 14 to connect the coil 15 of an electro-magnetic valve to the thermocouple. The electro-magnetic valve then opens against biasing means to supply gas to the main burner 17 which is ignited by the pilot burner. Energization of the coil 15 of the electro-magnetic valve causes the current flow in the control circuit to reduce to a value just sufficient to hold in the relay.
