Title: Improvements in apparatus for regulating gas pressure in closed pneumatic systems
IPC: F41A25/20
Filed: 1939-06-01
Abstract: 579,150. Recoil apparatus for guns. VIALE, S. M. June 1, 1939, No. 16206. [Class 92 (i)] [Also in Group XXIX] Apparatus for regulating the air pressure in a chamber 12 in open communication with the recoil cylinder 10 of an aircraft gun, so as to maintain the normal and the maximum pressures in the chamber under varying temperature conditions, includes an air reservoir 14, the pressure in which is between the normal and the maximum in the chamber, and a spring- loaded valve 15 controlling automatically communication between the reservoir and the chamber. The valve 15 is controlled by a spring-loaded diaphragm 17 carrying a spindle 19, the upper end of which coacts with an abutment 21 loaded through toggles 22 by springs 23, while its lower end engages a lever 25 pivoted to the valve 15 and having fulcra 26, 27. When the aircraft climbs, the consequent fall in temperature results in a pressure drop in the chamber 12 so that the diaphragm moves down and opens the valve 15 to admit air from the reservoir to the chamber. An increase in temperature causes the diaphragm to rise to again open the valve and permit air to pass from the chamber into the reservoir. In a modification, communication between the chamber 12 and the reservoir 14 is controlled by two valves, one allocated to each direction of transfer of air.

Filed: 1951-07-09
Abstract: 716,431. Axle-boxes. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. July 9, 1951 [July 10, 1950], No. 16255/51. Class 12(1) [Also in Group XXXII] A journal box assembly for a railway vehicle comprises a bearing having rollers 4 supporting an axle 1, and fluid pressure flanges attached to the ends of the axle &c. for damping axial movements of the axle. Under load the bearing surfaces between rollers and race will be rectangular, Fig. 7, and transverse motion of the axle from right to left will deflect or deform the surface to the chain dotted position before actual sliding takes place so that the roller will travel a helical path in direction B deviating from the straight forward direction A by an angle usually less than 1 degree. It is desired to reduce the axial force below the sliding frictional resistance of the roller to prevent sliding and possible scoring. The damping mechanism comprises a plate 11, Fig. 1, adapted to compress fluid such as air, oil, &c. in space 15, leakage through the clearance space 13 providing regulation. A second chamber 14 is provided into which fluid from 15 leaks and builds up pressure under control by clearance 16. In a modification, a piston or other sealing ring is positioned between walls 11. 17, and fluid release holes are drilled in these walls below the ring. In a further modification, three separately sealed chambers in addition to the chamber 15 are provided in which the axle will alternately raise and reduce pressure. In yet further modifications a clearance is provided between an inner race abutment ring and cover 12, the restriction extending over a longer surface to increase resistance to fluid flow; or a ball bearing attached to the end of the axle moves back and forth with the axle within the cover 12, close clearances between cage and race permitting leakage. In all these embodiments pressure and suction act to retard axial movement of the axle.

Abstract: 762,027. Electric motors. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 25, 1955 [June 3, 1954], No. 16479/54. Class 35. [Also in Group XXXVII] A portable device for actuating switchgear winding mechanism comprises a frame carrying a driving shaft 7 adapted for separable engagement with the winding mechanism, an electric driving motor for the shaft having its stator eccentrically mounted for angular displacement about the shaft axis in response to reaction torque upon the stator, springs 15 arranged to oppose the reaction torque, and limit switches LS<SP>1</SP>, LS<SP>2</SP> responsive to angular displacement of the stator in excess of a predetermined amount for effecting de-energization of the motor. The portable frame comprises tubular end members 1, 2, joined by horizontal members 3, 4, 5 and the frame is provided with a carrying handle 3<SP>1</SP>. The unit 6 is capable of swinging about the axis of the shaft 7 under the influence of the reaction torque which is set up when the winder is being used, and the unit is provided with lug 13 co-operating with springs 15 which act upon the unit in opposition to the reaction torque. Operating arms 16, 17 of the limit switches engage opposite sides of the unit 6, each switch being effective for one direction of rotation of the driving motor. The portable frame also carries a main contactor for the driving motor, a push-button unit for starting and stopping the motor, and a selector switch for reversing. In another arrangement, both ends of the driving shaft are engageable with the winding mechanism, either direction of winding being obtainable by selectively engaging the appropriate end of the shaft with the winding mechanism. The angular displacement of the motor stator is then always in the same direction so that only a single spring and limit switch are required.

Title: Fluid pressure actuated disc brake

Abstract: 1,033,967. Feeding webs. JAGENBERGWERKE A.G. April 26, 1963 [May 12, 1962], No. 16480/63. Heading B6B. [Also in Division F2] In a fluid-pressure operated disc brake (see Division F2) for paper converting machines, such as rewinding and cross-cutting machines, a stationary support 1 carries a rotatable shaft 2 which supports brake discs 4 and 5 driven by the axle shaft RS of the roll R of the paper converting machine through a slidable coupling RH, 51. When compressed air is admitted through separate lines 15, 16, outer (8, 6) and inner (9, 7) ring piston and cylinder devices are actuated to urge the rotatable brake discs 4, 5 against the side surfaces 20, 21 of the stationary support 1. At the commencement of operation when the roll of paper is at its greatest diameter, the braking force is applied simultaneously to both pressure chambers 6 and 7 so that maximum braking force is applied. As the paper is fed off the roll the diameter decreases and the braking force must therefore decrease. A stepless decrease in the braking force is achieved by altering the setting of a pressure regulating valve which receives a control impulse from an impulse roller influenced by the paper web. The stationary support 1 may be of hollow construction and adapted to be filled with a cooling medium (3).

Title: Improvements in and relating to the vulcanization of rubber
IPC: C08K5/00
Filed: 1935-06-07
Abstract: The vulcanization of rubber is accelerated by the addition of a compound of the general formula <FORM:0451000/IV/1> where Ar is a substituted or unsubstituted arylene radical, R is a group containing a partially or completely hydrogenated furane ring, and R<1> and R<11> are selected from hydrogen, alkyl, alicyclic, aralkyl or heterocyclic groups or together form an alkylene chain which may if desired be interrupted by an oxygen or sulphur atom.  The compounds are prepared by the interaction in an inert solvent such as petroleum of an arylene mercapto thiazole with an amine which is substituted by at least one radical containing a partially or completely hydrogenated furane ring. The arylenemercaptothiazole may be substituted by halogen, nitro, hydroxy, alkoxy or amino, and numerous examples are given of such compounds.  Amines which contain a furane ring and are reactive with the above arylenemercaptothiazoles have the general formula <FORM:0451000/IV/2> where R, R<1> and R<11> are as defined above.  They are prepared by hydrogenation of the corresponding compounds containing unsaturated furyl radicals.
