Title: Improvements in or relating to roller-type applicator for paint
IPC: B05C17/02
Filed: 1953-08-07
Abstract: <PICT:0752551/III/1> An applicator for paint or the like comprising a hollow cylindrical roller 14 having a paint-absorbing outer surface 15 is frictionally engaged at each end by means, e.g. an end cap, for mounting the roller 14 on a straight axle 13, one of the end caps, 25, being secured to the axle 13 to suppress axial movement of the roller 14 therealong, but to permit relative rotary movement therebetween.  Each end cap has a ange 28 to receive the roller 14, an annular ring 26 slotted at 27 to give the cap resilience and facilitate the engagement in the roller 14, and a hub 30. The axle 13 passes through the hub on the right hand side of the roller 14 and is bent to form a handle.  The opposite end of the axle 13 has a reduced part 32 which under lies a transverse slot 35 in the hub 30 which receives one arm 36 of a V-shaped clip which prevent axial movement of the hub 30, and therefore of the roller 14, on the axle 13.  To disassemble the device pressure is applied to the right hand end cap, the arm 36 being pushed by the hub 30 up a bevelled part 33 on the axle 13 and up the slot 35 to disengage the part 32 of the axle 13.

Title: Improvements in electric wave-form indicators or oscillographs
IPC: G01R23/00
Filed: 1919-09-05
Abstract: 160,196. Trichard, P. Sept. 5, 1919. Current meters.-The ordinate corresponding to any phase-angle of an alternating electromotive force E to be analysed is determined by the steady reading of a voltmeter V connected across a condenser A in a circuit including the plate P and filament F of a thermionic valve. Between the filament F and the grid G there is introduced an electromotive force D which is the sum of a constant pressure, from a source such as a battery B, and a sinusoidal alternating current C of an amplitude nearly equal to the pressure of the battery B. The pressure D is fairly high compared with the crest value cf the tension E to be analysed. Means are provided for varying the phase of the alternating current C with respect to that of the tension E to be analysed, the reading of the voltmeter V corresponding to each phase-angle being noted. The sinusoidal current C may be obtained from the tension E by the means shown. A resistance r, inductance l, and a pair of condensers c, c<1> are connected in series. and the condensers adjusted to resonance with the fundamental frequency. Alternatively, the harmonies of the tension E may be choked out by connecting a resistance and inductance in series across the tension E, another resistance and inductance in series across the resistance, and so on. The phase of the current C is varied by means of a rotating-field phase variometer H having coils of different impedance, the phaseangle being determined by the position of the movable coil. The phase variation may alternatively be effected by a resistance, a coil, and a condenser in known manner, cr by a small alternator, giving a sinusoidal wave, variably coupled with the alternator of which the wave form is to be determined.

Title: Improvements in and relating to rectifier tubes
IPC: H01J17/58
Filed: 1928-07-28
Abstract: 294,665. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). July 28, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vacuum tubes.-In a gas-filled thermionic rectifier having an oxide cathode, particularly for providing the H.T. current for wireless receivers, in order to lessen the risk of back ignition the anodes are constructed of or coated with materials having a low electron emission at operateing temperatures. To attain this property, the metals of the anodes may be purified by heating to their melting point in a high vacuum, or they may be coated with low-emission materials, e.g. chromium or its oxide. To prevent the deposition on the anodes 2 of active oxide from the cathode 4, this is surrounded by a metal shield 5 placed close to it and either electrically connected to, or insulated from it, and to prevent deposition of the getter on the anodes it is placed on the inner side of the shield 5, and the glass wall of the tube may be cooled during vaporization of the getter. The incandescent cathode may be dispensed with and its function served by the highly-emitting layer of getter on the inner surface of the shield 5. The anode leads are protected by shields 3.

Patent GB-871491-A (GB)
Title: Process for the separation of organic compounds
IPC: B01D53/02
Filed: 1956-08-23
Abstract: Mixtures of organic compounds are separated into their components by feeding the mixture into a vertical column containing an inert solid presenting a large surface area <PICT:0871491/III/1> but of low resistance to flowing liquids, through which passes an eluent gas in counter current with a liquid solvent.  The rate of flow of the gas, solvent, and liquid to be separated may be regulated whereby one or more components flow to the top or the bottom of the column, or a selected component may be concentrated at a selected zone and removed therefrom.  These effects may also be controlled by a temperature gradient.  The liquid mixture to be separated may contain organic components of close boiling range, e.g. hydrocarbons, or azeotropic mixtures, e.g. water and alcohol; petroleum ether mixtures, and essential oils.  As liquid solvent there may be used, paraffins, esters, ketones, glycols, nitriles, or silicone fluids.  As gaseous eluent, air, hydrogen, carbon dioxide, methane, steam or flue gas. The process may be used as a control to chemical processes, in which effluents are analysed, e.g. by chromatography.  In a suitable apparatus two packed columns SC SH are used, the upper one being at a constant temperature and the lower one at a higher temperature which may also be varied.  Eluent gas enters the bottom of SH and passes upwards to a detector D and flow meter FG.  The liquid solvent is passed by a pump P through a flow meter PL and cooler C to the top of column SC.  The mixture to be separated is introduced at the junction of SC and SH, and with a high liquid/gas ratio, the most volatile component of the mixture will be unable to move in SC, and the higher temperature of SH prevents it moving downwards. This component is therefore trapped at the junction until the liquid/gas ratio is reduced when the component moves slowly through SC and the slower moving component will be removed from it yielding a pure component at the top of the column.  By further reducing the liquid/gas ratio a second pure component will arrive at the top of the column.  The packing in the columns may consist of gauze rings, metal pieces, or porous solids, e.g. pumice, diatomaceous earth or bauxite.  In examples, a mixture of propane, isobutane, and n-butane, are separated using in the columns, air and kerosene: a mixture of isopentane, n-pentane is also separated using air and kerosene.  By adjusting temperatures and flow rates, the separated components may be moved upwards or downwards. Specifications 871,492, 871,493, 871,495, 871,496, and 871,497 are referred to.

Patent GB-475296-A (GB)
Title: Improvements in process for manufacture of mercapto aryl thiazoles
Filed: 1936-08-11
Abstract: An increased yield of mercapto-aryl-thiazole is obtained, due to a diminution in the amount of byeproducts formed if in an equilibrium reaction in which byeproducts are formed, the byeproducts are extracted from the crude reaction product and added to succeeding batches of reaction ingredients.  The preferred process to which the invention is applied is that in which mercapto-aryl-thiazoles are formed by the interaction of carbon bisulphide, sulphur and a primary aromatic amine.  The tars which form the byeproducts are leached out of the reaction product with carbon bisulphide, benzene, toluene, or other hydrocarbon solvent, and added to a succeeding batch.  In the process just referred to it is preferred to use carbon bisulphide as the leaching agent since it need not be removed as must a hydrocarbon solvent, but allowed to remain as a constituent of the succeeding batch.  The process of the present invention may be applied to both batch processes and continuous processes.  The application of the process of the present invention is illustrated by an example in which the byeproducts from the interaction of aniline, sulphur and carbon disulphide were leached out with carbon bisulphide, and added to a second batch.  The aniline may be replaced by another primary aromatic amine having a replaceable hydrogen on an ortho carbon atom such as the toluidines and naphthylamines. Specification 283,679, [Class 2 (iii)], is referred to.
