Title: Fluid-flow control valve
IPC: F16K5/06
Filed: 1962-02-02
Abstract: 959,631. Valves. CAMERON IRON WORKS Inc. Feb. 2, 1962 [Dec. 21, 1961], No. 4126/62. Heading F2V. A fluid-flow control valve comprises a body 11 having a chamber 12 in which a closure member 15 is mounted, a reciprocable seat member 25 for co-operation at its inner end, with the closure member, a sealing ring 29 for engagement with a shoulder 34 on the body or on an adaptor member forming part of the body and spring means 30, 31 for urging the ring into sealing engagement with the shoulder with a first force and, the inner end of the seat with the closure member, with a second force which is less than the first. The ring 29, which may be of polytetrafluoroethylene, is so shaped that the force produced by the spring 30, via a ring 31, causes a greater pressure of the ring 29 on the shoulder 34 than the seat pressure on the closure member; a ring 28, of P.T.F.E., may be fitted in the seat ring. A further ring of P.T.F.E. may be fitted in the sloping surface 36 of the seat for engagement by the ring 29. Gear means 26, 27 are provided on the closure member and seat for rotation of the latter in order to effect even wear of the ring 28. In the modification shown in Fig. 3, an adaptor ring 38 is provided having a P.T.F E. ring 39 urged into contact with a shoulder 39a on the body. In a further modification, the ring is urged into contact with the shoulder by the spring 30 and the seat member into contact with the closure member by means of a helical spring mounted on a retaining member. Specifications 840,897, 841,019 and 919,297 are referred to.

Armouring vehicles; fieid carriages; housing.- Consists in a portable shield comprising a cylindrical shell adapted to roll on the ground and made up of two or more segments capable of being opened out. A machine gun, housed within the shield, may be raised to the firing position when the parts of the shield are opened out. A roller, Fig. 1, is made of halves a., a<1> connected together by pivots b, b<1> at one edge and by a cross-arm h at the opposite edge, so that when it has been. upset so as to rest on edge on the ground with the pivots above, the half a can be turned over to rest on the half a<1> as in Fig. 6, the pair then forming a. semicircular shield. An aperture f with shutter allows firing and a machine gun k may be carried within by an arm m normally holding the trunnion-block of the gun against a ledge n but adapted to lift it to a ledge o in which position the gun protrudes.

Title: Improvements in or relating to the production of expanded joists or the like
IPC: B21D47/02
Filed: 1930-02-08
Abstract: 348,183. Making expanded metal. WHITE, A. E., 5, Quality Court, Chancery Lane, London.- (Kalman Steel Co. ; Wrigley Building, Chicago, U.S.A.) Feb. 8, 1930, No. 4332. [Classes 83 (ii) and 83 (iv).] Expanding and stretching dies; shearing ; rolling.-In making joists &c. of expanded metal a blank having side flanges joined by a web is passed between rollers which slit the web by a nipping action, the blank then being passed through a die which separates the flanges and causes the web to be expanded without increasing the length of the flanges and the attached web parts. A blank having flanges F and a web W is formed by rolling in the usual manner at a temperature of about 1600‹ F. and may be passed directly to the slitting rolls 20, 21, or if allowed to cool is reheated in a furnace A before slitting. The slits are formed by ribs 22 on the rolls 20, 21, Fig. 3, which penetrate without displacing the metal from the plane of the web, clearances at the bases of the ribs receiving the metal displaced by their penetration. The expansion is preferably performed by a die 33 having a clearance space 35, Fig. 4, for the web and diverging ribs 37 which act on the inner surfaces of the flanges to progressively spread them apart as the beam is drawn through. Clearances 38 are provided at the outer surfaces of the flanges and are considerable in the tapered portion of the die to reduce friction but become less in the final parallel portion. The ribs 37 extend towards the slitting rolls beyond the remainder of the die and have upper and lower shoes at the forward end for guiding the flanges F. In passing through the parallel portion of the die the flanges are smoothed and set definitely in a parallel relation. On emergence from the die upper and lower finishing rolls 41 act on the expanded web to set the struts accurately in a plane, the rolls 41, 20, 21 being positively driven for feeding. The web may be given more or less than the three rows of slits shown in Fig. 3.

It is driven from the roller 8 through a friction wheel 21 and pulleys 20, 22, 23, 24, the pulley arm 18 being pivoted on a lug 19 on the casting 13 and the spindle for the pulleys 22, 23 being carried by a lug bearing 26 on the arm 18. Foot-rests 28 of pierced sheet metal, or of skeleton form, are secured to the platform extension 12 and are provided with stays 30. The transmission gear comprises a rotary member 31, mounted on a fixed axis on lugs 33 on casting 1, and a rotarv member 32 mounted on an axis movable about a pivot on a lug 34. Both members 31. 32 are grooved to effect forward travel by belt or reverse travel by frictional inter-engagement, four grooves 35 being provided to accommodate four belts and three intervening friction rings 36 on one member 31 to engage three intervening grooves 37 on the other member 32. The fixed bearing 38 of the transmission gear is directly attached to the lugs 33, the sprocket 39 for driving the clutch shaft being arranged outside the bearing.

Title: Improvements in Methods and Apparatus for Sintering Ores.
Inventor: GAYLEY JAMES
IPC: F27B21/06
Filed: 1918-03-14
Abstract: 115,023. Gayley, J. March 30, 1917, [Convention date]. Drawings to Specification. Roasting.-In a method of sintering ores, &c., the material is spread in a continuous layer on a train of abutting cars, which are moved beneath the usual ignition-apparatus, and over the draught chamber to the discharging-point, where the layer is broken by detaching the end car. This is then separated from the rest of the train by moving it at increased speed, and is run on to a dumping-car. The dumped material passes over a screen and the finer portions are separated from the lumps and delivered separately. Any material which falls when a car is broken off from the train is similarly dealt with. The cars are preferably formed with sides only, but where deep layers of the material are being treated, ends may be provided'of less height than the depth of the charge, so that the surface layer of the material is still continuous.
