Title: Improvements in or relating to Audion or Lamp Relay or Amplifying Apparatus.
Inventor: LATOUR MARIUS
IPC: H01F19/02
Filed: 1917-10-25
Abstract: 129,661. Latour, M. Oct. 23, 1916, [Convention date]. Addition to 127,318. Non - contactmaking relays. - High - frequency iron-core transformers, employed in connexion with vacuum - tube amplifiers in the manner described in the parent Specification, have the cross-section of the iron in the parts b, c external to the coils greater than the cross-section in the part a within the coils. The coils have several layers, the inner layer close to the central core a, and the outer layer remote from the external portion b of the magnetic circuit. The layers fit one within another, leaving considerable space between them. The central layer preferably forms the primary coil. Successive turns of the same coil layer may be separated by inserting, when winding, a thread of cotton, flax, silk, &c. This arrangement of the coils reduces the electrostatic or capacity effects in the transformer. The magnetic circuit may be insulated by supporting it on rings of ebonite or mica.

Anthraquinone dyes.-Dyestuffs of the anthraquinone series, presumably 1 : 1<1>-dioxy-2 : 2<1>-dianthraquinonyls, are obtained by fusing 1-oxyanthraquinone or a derivative thereof with caustio alkalies in the presence of an organic solvent or suspension medium, advantageously with exclusion of oxygen. The products may be purified by fractional precipitation from sulphuric acid or by treatment with oxidizing agents as described in Specification 292,897 and may be employed for dyeing in a faintly alkaline vat as described in Specification 292,658, [Class 15 (ii), Dyeing, Processes &c. for]. In examples, (1) 1-oxyanthraquinone is fused with caustic alkali and alcohol or aniline, access of air being prevented as far as possible; the product is run into water and the dyestuff precipitated by passing air through the solution; it dyes wool in pure yellow shades from the vat; (2) 1-oxy-4-aminoanthraquinone is fused with alcoholic potash in a current of nitrogen, the melt run into water and the dyestuff separated by blowing in air; it dyes wool in grey shades from an ammonia-hydrosulphite vat, and (3) 1-oxy-4-methoxyanthraquinone is similarly treated; the product dyes wool brown from a faintly alkalline hydrosulphite vat.

[Class 83 (iii)] A slider assembly for a metal-cutting machine tool, particularly a screw machine, comprises a slide 1 mounted for movement between a pair of guide rails 6, 6a, a tapered gib 8 adapted to be increasingly inserted between the slide and the rail 6a to compensate for wear, and means independent of the gib 8 for adjusting the rail 6a towards the rail 6 to an extent exceeding the wear adjustment of the gib and for clamping the rail 6a in an adjusted position. The slide 1 is recessed in its sides for the reception of the guide rails 6, 6a, each of such recesses having a horizontal top face 3 and plane faces 4 and 5 of a V-form. Each rail engages the adjacent slideface 3, partially engages the face 4, and has a face 7 which is spaced from the slide face 5 and converges gradually towards the face 5 from one end to the other of the rail. A gib 8, which is formed at its thickest end with a projecting lug 9, fits between the adjacent faces 5, 7 of the slide and the rails. Each lug 9 accommodates a stud 10 which is set adjustably in the end of the adjacent rail and carries a collar 11 and lock-nut 12 to hold the gib in adjusted position with respect to the end of the rail. Seatings 13, 13a integral with the rails bear on the walls 14, 14a of a channel-shaped support 15 and are clamped thereto by studs 16. The openings for the studs 16 in the rail 6a are elongated to provide transverse adjustment with the assistance of studs 18 in the wall 14a.

Abstract: 1,157,415. Extracting protein. KENNETH CHUNG LUM. 4 April, 1968 [12 April, 1967], No. 16274/68. Heading C3H. [Also in Division C5] A process for preparing a protein concentrate from fish comprises digesting the fish by enzymatic proteolysis to produce a liquid mixture containing emulsified oil and fat constituents, extracting the oil and fat constituents with a solvent and separating the fat-containing solvent to leave a fraction of high protein content free of fat. Preferably the whole fish is first reduced to particle form and the digestion is carried out at 125-145‹ F. by autolysis promoted by enzyme in the fish viscera. The liquid mixture may be screened, before solvent extraction, to remove fish bone and other solids. A suitable solvent is a mixture of hexane and isopropanol.

Abstract: 409,914. Containers for roll-films. 1. G. FARBENINDUSTRIE AKT. - GES., Frankfurt-on-Main, Germany. June 9, 1933, No. 16566. Convention date, June 9, 1932. [Class 42 (ii).] An apparatus adapted to deliver a predetermined length of roll-film, e.g. in a dark room, comprises a cover 2, Fig. 2, carrying an axle 9 on which the core 9<a> of the film roll 10 is maintained, the film passing over a roller 12 of a sprocket 13, which is thereby rotated and out through a velvet lined slit 15 where it is cut by being pressed on a knife and, if desired, wound on another spool carried on the apparatus. The rotation of sprocket 13 is controlled to give a predetermined length of film by mounting on its axle 13<a>, Fig. 4, a cam 18 which reciprocates a pawl 19 which with the co-operation of a pawl 21 drives a toothed disc 20 in the direction of arrow a against the action of a spring 28. Where a pin 23 on disc 20 meets a stop lever 24, a tooth 25 engages cam 18 and stops it, thus terminating the delivery of film. This apparatus is re-set by pressing down lever 27 which disengages pawls 19, 21 and allows disc 20 to return till a pin 29 contacts a stop 30. The length delivered is adjusted by varying the position of stop 30 which for this purpose is mounted on a disc 31, Fig. 6, rigid with an axle 35 on which is fixed a graduated knob 16, the disc 31 carrying a pin 32 which may be engaged with any desired perforation 33 in casing 34 by pressing disc 31 inwards against a spring 38, rotating it till pin 32 is in the desired position, and then releasing it so that pin 32 engages a perforation in the casing.
