Filed: 1943-10-27
Abstract: 569,799. Hydraulic transmission of power. UNITED AIRCRAFT CORPORATION. Oct. 27, 1943, No. 17733. Convention date, Oct. 5, 1942. [Class 69 (ii)] [Also in Group XXVI] In a hydraulic engine of the oscillating-vane type, such as used in the hub of a variablepitch aircraft propeller, each vane 24 and abutment 16 has a backing plate 32 or 56 with rubber packing moulded to the plates. The cap may be a die casting or of sheet metal, and may move relatively to the vane or abutment for self-adjustment. A cylindrical member 10 is attached to the propeller hub by a flange and has a surrounding, tubular member 14 which carries the abutments 16. The members 10 and 14 are attached to each other by splines 18. An outer rotatable member 20 carrying vanes 24 is attached to the 'interior of the propeller blade shank by splines 22. The vanes 24 are rotated relatively to the abutments 16 by oil flowing in to or out of arcuate chambers 26, 28 through ports 30, 32 under control of the pilot or a governor. The sides of the packing are cup-shaped to allow the oil to press the edges of the packing outwards. A cap. Fig. 6, for a vane has an outer curved plate 38 and bent-up tabs of metal which are embedded in the rubber diiring moulding. Parts 44 serve as bumpers.

Title: Improvements in single powder photographic developers
IPC: G03C5/26
Filed: 1953-06-26
Abstract: 725,892. Photographic developing compositioris. KODAK, Ltd. June 26, 1953 [June 26, 1952], No. 17745/53. Class 98 (2). A single-powder photographic developing composition contains an organic silver halide developing agent, a water-soluble and photographically compatible basic ingredient comprising a hydrate of sodium metaborate containing less than 34.3 per cent of water of crystallization, and optionally boric anhydride (as a stabilizing agent) and an antifogging agent. In example 1, a thin layer of sodium metaborate tetrahydrate is dried on a metal plate at 550‹ F., and the powdered product is incorporated in a developing composition including also mono-methyl-p-aminophenol sulphate, hydroquinone, sodium sulphite, sodium bisulphate, potassium bromide, and boric anhydride. Examples 2 and 3 are similar, using the tri-, di-, and mono-hydrate and the anhydrous forms of sodium metaborate. The stabilizer and the treated sodium metaborate may be first mixed, the developing agent added and mixed, and the remaining ingredients added. The sodium metaborate tetrahydrate or the partially dried product as in example 1 may be mixed before drying with another ingredient, e.g. anhydrous sodium sulphite. The sodium metaborate tetrahydrate may be dried in an atmosphere of acidic gas, such as CO 2 , SO 2 , HC1, acetic acid, or nitrogen oxide. In examples 4 and 5, sodium metaborate tetrahydrate is treated with carbon dioxide and sulphur dioxide before incorporation in a single-powder developing composition. Specification 585,366 is referred to.

Patent GB-726378-A (GB)
Title: Improvements in the production of compounds of the pyridine series
Filed: 1953-06-30
Abstract: Compounds of the pyridine series including halogenated pyridine bases are prepared by reacting glutaric dialdehydes or d -ketoaldehydes, as such or in the form of their acetals; in particular in the form of their cyclic enol acetals, i.e. the 2-alkoxy-2,3-dihydropyranes, or the corresponding 2-acyloxy-2,3-dihydro-pyranes, at elevated temperatures in the presence of oxidizing agents with aqueous solutions of ammonium salts (e.g. ammonium sulphate, phosphate and halides).  Suitable starting materials are glutaric and b -methylglutaric dialdehydes, 2-methoxy-, 2-methoxy-4-methyl-, 2-ethoxy-4-methyl-, 2-ethoxy-4-ethyl-5-methyl-, 2-methoxy-5-methyl-, 2-ethoxy-5-methyl-, 2-methoxy-6-methyl-, and 2-acetoxy-2,3-dihydropyranes.  Suitable oxidizing agents are salts of metals in a higher valency state which are reducible to a lower valency state, e.g. salts of trivalent iron or manganese and divalent copper, and also hydrogen peroxide in the presence of iron or copper salts.  Ammonium ferric sulphate may be used simultaneously as the ammonium salt and the oxidizing agent. Mono- and di-halogenated pyridine bases are obtained by using as the ammonium salt and/or as the oxidizing agent the corresponding halides (e.g. ammonium chloride or bromide on the one hand and ferric, cupric or mercuric chlorides on the other hand).  It is also possible to work in presence of free chlorine, bromine or iodine and these are preferably added to the glutaric dialdehydes or dihydropyrane derivatives at low temperature before the addition of the oxidizing agent and the ammonium salt, halogenated pyridines being obtained exclusively when salts containing halogen ions are also added.  The process is carried out by heating the reactants together in aqueous solution or by allowing glutaric dialdehyde or the dihydropyrane derivative to flow into a heated solution of ammonium salt and oxidizing agent and may also be carried out under increased pressure and/or continuously. Mono-and di-halogenated pyridine bases are preferably separated from each other and from nonhalogenated pyridine compounds (formed simultaneously) by distillation of the reaction mixture at different pH values.  The examples describe the preparation of pyridine, b -picoline, g -picoline; 3-chloro-, 3,5-dichloro-, 3-chloro-4-methyl-, and 3,5-dichloro-4-methyl-pyridine.

[Also in Division E1] A buoyant body, e.g. a pontoon for a bridge, comprises a rectangular prismatic casing 1, Fig. 1, that is subdivided into three buoyancy chambers 4, 5, 6 by transverse walls 2, each chamber being open at the bottom and provided with a small orifice or bore 7 in one of its outer side-walls at a point remote from the lowermost edge thereof whereby the volume of air trapped in the chamber is controlled. Each orifice is sufficiently remote from said edge so that the air does not escape from the chambers when the body is eccentrically loaded, Fig. 2 (not shown). In a second embodiment, Fig. 4, the body constitutes a bathing raft and comprises two parts 9 of semicircular profile that are attached to each other by bolts or screws 13, a semicircular inverted trough defined by each part being subdivided into a plurality of bottomless chambers 12 by radial walls 11. An orifice 7 for each chamber is formed in the outer peripheral wall of each of said parts. A central opening between said parts is closed by a circular cover 18 that is stiffened by radial ribs 19, a mooring ring 20 being attached to the centre of said cover. Buoyant material (21), Fig. 3 (not shown), is lodged in the uppermost part of each chamber to render the raft buoyant in the event of air leaking therefrom. The raft may be made of, e.g. a synthetic plastics material, steel, low density metal or concrete and may be modified. Fig. 5 (not shown), so that the various parts are integral with each other. When the body is intended to support large loads, e.g. a crane, the orifices 7 may be replaced by non-return valves, Fig. 6 (not shown).

Winding-machines; stop-motions.-Relates to machines for winding yarns, threads, and the like, especially fine yarns such as silk and artificial silk, of the vertical spindle type and wherein the guide is moved upwards on a screwed rod, mounted on a reciprocating carrier bar and rotated mechanically. A vertically-disposed ratchet wheel 5 is geared with the screwed rod and is operated as the bar rises and falls by a pawl 6 which is displaced, so as to be inoperative when the yarn slackens or breaks, by a rod 18 carried on a spring-controlled arm 16. The yarn guide 11 is secured to the end of an arm 12, which engages with a nut 22 on the rod 4 and is splined to a rod 13 to which the arm 16 is secured, so that the tension of the intact yarn holds the guide close to the bobbin and the rod 18 clear of the pawl. The pawl is also moved so as to be inoperative when the yarn is unduly tensioned by means of a stop 35 on the lever 30 of the apparatus described in Specification 28480/13, which disconnects the spindle-driving discs. The screwed rod 4 is carried on a bracket which is pivoted on the reciprocating bar 1 and is engaged by a cam 29 so that the guide travels in a path parallel to the cone of the cop as described in Specification 181,155.
