Title: Improvements in and relating to wireless transmitting circuits employing thermionic valves
IPC: H04B1/04
Filed: 1920-03-16
Abstract: 166,634. Macrorie, A. K., Airey, H. Morris-, Shearing, G., and Randall, R. L. March 16, 1920. Thermionic oscillation generators.-In a method of producing high-frequency oscillations by means of thermionic valves, the anode tapping, instead of being made direct to the aerial coil, is made to an auxiliary coil shunted across a part of it. In the arrangement shown in Fig. 5, the anode tapping A is made to the double variometer W, W, which is shunted across any one of the sections of the aerial coil and is so arranged that an increase of the inductance of its upper part produces a corresponding diminution of that of the lower. As shown in Fig. 6, the anode tapping A is made to the coil H which is shunted across any section of the coil C, which is itself shunted across any one of the sections of the aerial coil. In a further form the coil H is omitted. The coil C is preferably an inductance but may be a resistance. The invention is applicable to producing oscillations in closed oscillating circuits.

Title: Improvements in or relating to the polymerisation of methacrylonitrile
IPC: C08F20/50
Filed: 1935-03-13
Abstract: Polymeric products are obtained by subjecting a mixture of monomeric methacrylonitrile and another polymerizable substance, other than butadiene or homologues or analogues thereof, also in the monomeric form and in an amount by volume less than the volume of the methacrylonitrile, to polymerizing conditions in a single-step process and in the absence of a plasticizer.  The polymerization may be carried out in the presence of a catalyst and in an aqueous medium or in the presence of a liquid which is a solvent for the monomeric mixture but which is a non-solvent for the polymer.  An organic dye soluble in the methacrylonitrile may be incorporated in the mixture, and the polymerization may be carried out in a mould of the shape of the article desired.  In examples: (1) mixture of methacrylonitrile with vinyl acetate, methyl acrylate or methyl or ethyl methacrylate are heated in the presence of benzoyl peroxide; (2) methacrylonitrile, methylmethacrylate and petroleum ether are boiled together under reflux with or without benzoyl peroxide; and (3) a mixture of methacrylonitrile and methyl methacrylate is shaken together with water, acrylic acid and triethanolamine, and the polymer precipitated by pouring the mixture into water acidified with hydrochloric acid.  Specifications 360,821, 401,653; 422,670, [Group VIII], 422,697, and 437,271 are referred to.  Reference has been directed by the Comptroller to Specification 351,508.

Abstract: 744,915. Two-part couplings. WALSALL CONDUITS, Ltd. March 15, 1954 [March 24, 1953], No. 7993/53. Class 38 (1). A shutter 27 for a socket connecter is locked in its operative position by lugs 22 on a plate 17 engaging slots 29 in the shutter. The plate rests on the open side of a U-shaped earth socket 12 and is held in position by a compression spring 34 operative between the plate and a member 30 pivotable at one end in the connecter body and loosely engaging the shutter at its other end 32. The plate 17 has lugs 24 engaging inclined slots 23 in the socket 12 and a bent-over lug 18 projecting across the socket. On insertion of a plug, the earth pin 25 engages lug 18 and displaces plate 17 axially and outwardly of the socket 12 thus unlocking the shutter. On engagement of the shutter by the " live " pins 33, member 30 is caused to tilt downwards and move the shutter to its inoperative position. Spring 34 returns the parts to their operative positions on removal of the plug.

Title: Improvements in photographic developers
IPC: G03C5/305
Filed: 1952-03-28
Abstract: 712,356. Photographic developing compositions. KODAK, Ltd. March 28, 1952 [March 28, 1951; March 28, 1951], No. 8004/52. Class 98(2) A photographic developing composition in wet or dry form contains diglycolic acid or an alkali metal salt thereof, and optionally an alkali metal polyphosphate, e.g. sodium tripolyphosphate, pentapolyphosphate, pyrophosphate, metaphosphate or hexametaphosphate. The diglycolic acid may be added to prevent precipitation of metals such-as calcium and aluminium to a developing bath replenisher containing metol, hydroquinone, sodium sulphite, sodium metaborate, sodium hydroxide, and sodium tetraphosphate. In examples 1 and 2 the alkaline powder B of a dry packet developer comprises diglycolic acid, sodium sulphite, sodium metaborate, and sodium hydroxide, the powder A in example 2 including sodium tetraphosphate. The diglycolic acid is included in powder A of example 2. Anhydrous sodium or potassium sulphate is mixed with the polyphosphate, e.g. sodium tetraphosphate, of a solid mixture to prevent caking. Antifoggants such as potassium bromide or iodide, 1 : 2 ; 3-benztriazole, or 6-nitrobenzimidazole nitrate are added to developing solutions to counteract the fogging effects of traces of iron in polyphosphates. Diglycolic acid and its alkali metal salts, particularly when used in conjunction with an alkali metal orthophosphate, exert a preservative (antioxidizing) effect with developers containing a hydrazine compound or water-soluble salt or acid addition salt thereof. Such developing compositions may include metol, hydroquinone, p-(#- methylsulphonamidoethyl)-phenylhydrazine hydrochloride, 5-methylbenztriazole, diglycolic acid, sodium sulphate, and sodium hydroxide, with or without trisodium phosphate. Similar developing compositions include as the hydrazine compound 1-naphthylhydrazine-7-sulphonic acid or a mixture of 1-naphthylhydrazine-6- and -7-sulphonic acids. Glycolic acid is of little effect as a stabilizer. The orthophosphate may also be NaH 2 PO 4  or Na 2 HPO 4 . In examples, four and two package dry mixtures are described. The hydrazine developers may be used in the production of a direct positive photographic image from a layer of an exposed internal latent image emulsion of the type defined in Specification 645,877, e.g. an emulsion as described in Specification 635,841. Specifications 642,616, 702,162 and 712,355 also are referred to.

Title: Improvements in and relating to combined variable speed hub gears for vehicle wheels
IPC: B62M11/14
Filed: 1946-03-20
Abstract: 630,129. Change-speed gearing. BURGESS, A. F. (Buchmann, A.). March 20, 1946, No. 8639. [Class 80 (ii)] In an epicyclic variable-speed gear contained in the hub 2 of a bicycle, the planet cage 14 has an extension which forms the inner member of a jamming roller back pedalling brake, the rollers 23 splaying open a fixed brake ring 24 which bears against a rotating part of the hub. The epicyclic gear, which comprises a fixed sun wheel 12, planets 13 and an annulus 15, is of known type where a cruciform member 10 is axially slideable to couple the planet cage, the annulus, and the annulus and ratchet mechanism 17 with a driving member 9, for high, medium and low speeds respectively. The planet cage 14 has an extension which is formed with inclined curved surfaces 22 on which bear the rollers 23 carried in a cage 30 which, when the planet cage rotates in a backward direction through back pedalling, ride up the inclines and splay open a brake band 24 which bears against a liner 29 in the light alloy hub shell 2. As pedalling has ceased before the planet cage commences to reverse its rotation, the pawl 33 of the freewheel connected therewith is pressed inwardly by the overrunning of the ratchet 34 and thus the extension 40 of the roller cage 30 can move over the pawl to hold it out of engagement until forward pedalling is resumed. When the bicycle is wheeled backwards the planet carrier tends to rotate backwards and thus operate the jamming roller brake, movement of the rollers however, rotate the cage 30 to allow end 40 of the slot 32 in the cage to co-operate with the cam 39 on the pawl 33 to hold the latter engaged with the ratchet 34 and thus the hub shell and the planet carrier rotate at equal speeds and the brake is not energised. To ensure the correct location of the roller cage 30 on assembly, the planet cage is provided with a pin 43 which co-operates with a slot 42 in the roller cage.
