Title: Improvements in or relating to voltage-regulating devices
IPC: G05F1/26
Filed: 1927-05-05
Abstract: 271,445. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. May 20, 1926, [Convention date]. Regulation, automatic.-The voltage of an a.c. load circuit 1<1>, 2' is regulated by electron discharge tubes and transformers in accordance with variations in the load current and supply voltage. Transformers 5, 7 have each one winding in series with the supply leads 1, 2, and the other in shunt with the supply and in series with transformers 6, 8 supplying the plate and filament circuits respectively of discharge tubes 3, 4. The transformer 5 has an air gap or other means to give it a heavy magnetizing current. The voltage drop in the secondaries 5<1>, 7<1> due to increasing load is nullified by the reduced plate current resulting in the valves which reduces the voltage of the reversed transformer 5. Increase in supply voltage increases the plate current, and the reversed voltage of the transformer 5. The transformer 6 may be dispensed with; the transformer 7 may be replaced by a resistance. In the former case the primary of transformer 5 is in series with the anode circuits of the valves or with a resistance, the anode circuits being in shunt with the transformer primary.

Filed: 1928-04-26
Abstract: 291,434. Holzverkohlungs-Industrie Akt.-Ges. June 2, 1927, [Convention date]. Acetic and other aliphatic acids.-Aqueous acetic or other volatile aliphatic acid is treated with an organic solvent such as acetone or wood spirit oils, ether, butyl alcohols or with mixtures such as acetone oil or butyl alcohol and benzene, and the organic solution is then treated with a salt such as potassium acetate or alkali or alkaline earth acetates which are capable of forming acid salts with the aliphatic acid. The aqueous acid may be extracted in a column with the organic solvent in counter-current, and the organic solution may be then treated in another column with potassium acetate solution in counter-current. The acid acetate is extracted from the solution by cooling, for instance in cooled jigging-troughs, and the neutral acetate and mother-liquor may be used again. The process may be effected at ordinary or slightly raised temperature such as 30-40‹ C. The acid acetate may be dried and heated, for instance to 200‹ C. with or without vacuum to expel acid, or may be utilized direct, for instance for the production of esters. When pyroligneous acid is treated, it may be first freed from tar. The Specification as open to inspection under Sect. 91 (3) (a) states that the acetate may be used in the solid' state. This subject matter does not appear in the Specification as accepted.

[Also in Division F4] A method of making a basic refractory brick comprises applying two metallic plates of channel section to a brick such that the plates embrace the brick with the webs of the plates abutting two opposed faces of the brick and indenting the flanges of the plates to produce indentations which penetrate and key the flanges to the brick. The brick 1 with a pair of channel-section plates 2 of an oxidizable metal and having equal lengths is assembled in a machine 7 comprising a fixed platen 8, an hydraulically or pneumatically operated platen 9, a pair of clamping plates 11, 11<SP>1</SP> and a pair of hydraulically or pneumatically operated indenting dies 16. The clamping plates are pivotally mounted on horizontal axes 12, 12<SP>1</SP>, to blocks 13 slidable on guides 14. The plate 11<SP>1</SP> is set in a horizontal plane and a brick and plate assembly passed from a conveyer on to the platen 8 and against the vertically disposed plate 11, the plate 11<SP>1</SP> is then raised to the vertical position to clamp the brick across its un-cased end faces. The platen 9 is lowered to clamp the plates 2 about the refractory material and the indenting tools advanced to indent the flange portions of the metal plates into the surfaces of the brick. The dies 16 are mounted on rams 15 which are mounted on members 18 adjustable by way of a lead-screw (not shown) towards and away from the brick. After indenting, the platen 9 is withdrawn, the plate 11 pivoted into a horizontal position and the assembled brick ejected on to a conveyor by an ejector 19<SP>1</SP> pivotally mounted to the platen 9. The ejector subsequently returns to its rest position and the plates 11 are rotated into their loading positions to restart the cycle. The edge faces 6 of the flanges may abut one another or be spaced apart substantially parallel to each other. The machine may be arranged to operate automatically. For the manufacture of longitudinally tapered bricks one or both of the clamping plates 11 may be arranged to pivot about vertical axes.

Title: Process for crimping thermoplastic yarns and yarns produced by such process
IPC: D02G1/12
Filed: 1964-03-24
Abstract: The compressive crimping process of the parent Specification is applied to an assembly of continuous filaments which may consist of a low or bundle or be formed by two or more yarns with a total count of up to 200,000 denier and individual fibre count of 1.5-40 denier. The filaments are of thermoplastic material e.g. cellulose acetate or triacetate, polyamides, polyesters, polyolefines or polyacryl or polyvinyl derivatives, but the assembly may contain a small proportion of non-thermoplastic filaments.  The tow may have been previously crimped by conventional means e.g. in a stuffer box, in which case the present process enhances the bulk thereof.  Two or more yarns of similar or different count and/or material may be fed to the crimper at identical speeds, to produce a crimped assembly of large count the constituents of which may then be dissociated, or at different speeds to form a cored or "chenille" yarn in which the yarn introduced at the lowest speed constitutes a core and the others the effect yarns with the loops thereof interengaged. The filaments may be impregnated before crimping with dye liquids of like or unlike colours.  The crimped filaments may be stapled and spun in such form or blended with other natural or man-made fibres.  Specification 977,937 also is referred to.
