Title: Improvements in or relating to the manufacture of phenoxyalkylcarboxylic compounds
IPC: C07C51/44
Filed: 1945-05-29
Abstract: Salts of phenoxyalkylcarboxylic acids free from the odour of phenol are obtained by removing unreacted phenols by adding to the solution or suspension of the salts a mineral acid in an amount sufficient to liberate the phenol or phenols from their salts without decomposing the salts of the phenoxyalkylcarboxylic acids, and subjecting the product to steam distillation when the phenoxyalkylcarboxylic acids have been prepared either by reacting a phenol with an a -chloroalkylcarboxylic acid containing not more than four carbon atoms in the presence of aqueous alkali, or by reacting equimolecular proportions of a phenol and an a -chloroalkylcarboxylic acid as defined above and then adding a further quantity of the acid with a slight excess of alkali.  In examples, unreacted phenol or phenols are removed by the addition of hydrochloric acid and then steam distilling the aqueous solution or suspension obtained in accordance with Specification 573,510 of (1) mixed sodium methylchlorophenoxyacetates; (2) sodium phenoxyacetate, and (3) sodium 2 : 4 - dichlorophenoxyacetate.  Specification 573,477 also is referred to.

Title: Quartz mercury vapour lamps
IPC: H01J13/00
Filed: 1921-05-12
Abstract: 165,081. Quarzlampen-Ges. June 17, 1920, [Convention date]. Low-pressure metallic-vapour apparatus. - A quartz lamp, provided with electrodes of mercury only, contains such a small quantity of mercury that the ignition period, or the time required for the attainment of full voltage, amounts to only five to eight minutes. For this purpose the mercury at the cathode K, Fig. 1, is restricted to a thin layer by means of a hollow quartz tube c fused in or spaced by projections d in the cathode container. A thickened tube f, of small diameter, connects the cathode container with the lighting tube a, which is of uniform diameter. The anode container is kept almost empty of mercury, and is provided with a depression g, which is formed between two cylindrical sloping parts, as shown in Fig. 3, and is of such size as to contain only sufficient mercury to start the arc by tilting. A quartz plate h or a round or other bar, arranged so as to be readily replaceable, may be inserted in front of the anode container so as to steady the arc. In a modification, Fig. 4, the anode container A<1> is arranged vertically, and is connected with the lighting tube a by a thickened tube f<1> of small diameter, and by a tube for equalizing the pressure. The use of a small quantity of a mercury, the plate h, and the restricted passages, reduces the risk of breakage during transport. Specification 23318/05 is referred to.

The cam is rotatable on the hub 104 of the wheel 103, which is itself rotatable on a shaft 102. When a switch-arm 130 is moved to a contact 131, it operates a contactor 127, so as to energise the motor 20, through a shunt winding 141, and the coil 31 of an electromagnetic clutch, whereupon the motor rotates the wheel 103, through the clutch plates 27, 30, hypo-cyclic reduction gearing 48, 74, 75, 76, and worm and pinion 50, 51, until the load-carrying nut 80 reaches the limit of its down-ward travel, and the key 108 engages the end 112 of'the cam-slot 109, to close the switch 118 and open 119. When the switch-arm 130 is moved to a contact 150, it operates a contactor 126 so as to energise the motor 20, through a series winding 155, and the clutch coil 31, whereupon the motor rotates in the reverse direction until switches 118, 119, open,and close, respectively, to stop the nut 80 at the limit of its upward travel. The switch positions may be adjusted by screws 122, 123. The Specification as open to inspection under Sect. 91 refers to Specification 575,263. This reference does not appear in the Specification as accepted.
