Abstract: 830,991. Combing machine draw boxes; stop motions. T.M.M. (RESEARCH) Ltd. July 18, 1958 [Aug. 29, 1957], No. 27254/57. Class 120(2) A combing machine draw box has the upper drawing rollers and calendar roller mounted on two spaced arms capable of being raised together as a unit by pivoting about a horizontal axis at the rear of the draw-box. Each upper roller 23, 24, 26 has end bearings carried in bearing- blocks 21, 22, 25 adjustable in arms 20. Each bearing block houses roller-loading springs and the arms 20 are held in operative position by hooks 30 movable by levers 31 and cams 32. Ermen type clearers may be applied to upper and lower drawing rollers. If a roller lap forms on the front upper drawing roller an electrical stop motion brings the machine to rest; for this plungers incorporated in the roller bearings may rise to close a switch on a roller arm.

Title: Improvements in or relating to smelting metalliferous materials containing lead and zinc in a blast furnace
Inventor: MORGAN STEPHEN WILLIAM KENNETH
IPC: C22B19/36
Filed: 1953-10-06
Abstract: In a method of smelting in a blast furnace metalliferous materials containing lead and zinc together with some sulphur, the material is treated to reduce its sulphur content to below 1.5 per cent before being fed to the furnace.  The sulphur may be reduced in a sintering operation, the furnace charge being formed of coarse porous sinter and carbonaceous material.  Free lime or metallic iron may be included in the charge to trap any sulphur remaining and to inhibit volatilization of lead sulphide.  The furnace may be operated so that the temperature of the zinc-containing gases leaving the charge is only slightly above the equilibrium temperature below which zinc vapour would react with carbon dioxide to form zinc oxide.  An oxygen-containing gas can be introduced into the zinc-containing gaseous product to raise this temperature by oxidation of the carbon monoxide thereby ensuring that zinc is not oxidized during passage to the condenser.  Specifications 682,176, 686,542, 726,530 and 741,243 are referred to.

Abstract: 459,961. Pressure-regulating valves. BENDIX, Ltd., and ROBERTS, G. P., King's Road, Tyseley, Birmingham. Oct. 7, 1935, No. 27599. [Class 135] A valve device for limiting the fluid-pressure load which can be applied through one of two pipe lines comprises a spring-loaded piston g carried by a hollow piston rod f, which, when the fluid pressure on the piston overcomes its spring load seats on the inner end of an axial outlet r from a chamber k into which the piston rod passes and cuts off a lateral outlet p from this chamber from further fluid pressure supply. The device may be used to limit the pressure applied to the rear wheel brakes of a fourwheeled vehicle in which case the outlets r, p are connected to the brake cylinders of the front and rear wheels respectively and the inlet c is connected to a master cylinder or other source of fluid pressure. The cylinder containing the piston g and the chamber k are formed in a single casing a having a ported partition j forming an abutment for a pre-loaded spring l which presses a collar m against a cup leather h on the piston. A cup leather n seals the chamber k. The outlet r which is in permanent communication with the inlet c is formed in an end closure q with a conical surface s to engage a similar surface t on the piston rod. A closure plug b at the other end of the casing has an inner ported projection d. According to the Provisional Specification, the axial outlet may be omitted when the device is fitted in the pipe line leading to the rear brake cylinders only.

Class 34(2) In an article coating and drying apparatus the articles are carried on elements 17, Figs. 4, 5, along an endless track 16 by an endless conveyer chain moving along a track 15. The articles, which are loaded at 24, Fig. 1, dipped at 21, dried in a chamber 12, stored at 25 and 26, and unloaded at 23, are moved intermittently in fixed units of time, e.g. 120 seconds, the necessary control being derived from a timer device 18 located in the drying chamber 12 part of an oven 11 which has respective upwardly and downwardly inclined entry and exit passageways 13, 14. The respective passageway inlet and outlet, 27, 29, is disposed below the level 28 at which the drying medium is introduced into the chamber 12. Each element 17 carries an arm adapted to engage a part of the conveyer chain and placed at suitable positions along the article path are groups of devices 20 which upon actuation-at the end of each fixed time uniteither simultaneously link to the chain the elements under them or next to pass under them or simultaneously break such engagements. Each group 20 is mechanically controlled by a sub-controller 19 which receives electrical impulses from the timer 18. The devices 20 and 19 are so placed that the distance between the moving articles in the passageways 13, 14, is greater than that in the chamber 12. Preferably only one article is travelling along a passageway at one time and such travelling is accomplished in the fixed time unit. If elongated articles needing two or more elements 17 are to be treated, supplementary tracks are provided in association with each passageway 13, 14, so that on passage therethrough, the line-ahead carrier formation adopted throughout the rest of the endless path is changed to lineabreast the articles being then, in plain view, at right angles to the passageways.

Abstract: 204,914. Dolman, H. J. Oct. 14, 1922. Regulating; valves.-A revolving-cylinder engine is made to work on a two or four-stroke cycle by placing between the admission manifold and the carburettor a cam-actuated valve K, Fig. 4. The carburettor is connected to the inlet I; for a multicylinder engine when on the two-stroke cycle, mixture only is admitted, but when working on the four-stroke cycle, the valve alternately admits mixture from the carburettor and air through the sleeve J, this sleeve acting as a seating to cut off the air supply during alternate admission strokes to the crank cases. The sleeve may be adjusted so as always to admit a small amount of air. As applied to a three-cylinder engine, the stationary hollow crank shaft f serves as the admission manifold, the big ends of the connecting-rods e and the shaft being ported to act as the admission valves to the crank chambers.
