Title: Metal shot
IPC: C22C1/04
Filed: 1974-02-28
Abstract: 1459528 Sintered metal shot CANADIAN PATENTS & DEVELOPMENT Ltd 28 Feb 1974 [6 March 1973] 8892/74 Headings C7A and C7D [Also in Division F3] Metal shot is provided of a heterogeneous composition consisting by weight of:- and is particularly suited for use as non-toxic bird shot (see Division F3). The shot may have particles of iron dispersed in a matrix of the other ingredients, or may be iron impregnated with the lead alloy. Preferably, the iron concentration diminishes from a maximum in the inner layers of each particle. In one embodiment, the metal powders are dispersed in an organic liquid, optionally together with pre-formed nuclei of metal particles, and a second, aqueous, liquid is applied by spraying on to the agitated dispersion to form agglomerates; alternate applications of metal powder, e.g. of varying composition, and aqueous spray form successive layers. The resulting balls are separated from the liquids, sintered at below 1200‹C and optionally compacted e.g. by rolling between hard surfaces or by subjecting to richochet impacts in a container. A pre-alloy of the alloy particles may be used; the zinc may be incorporated by sintering in an atmosphere of zinc vapour: and iron oxide powder may be a starting material, a reducing treatment being incorporated prior to sintering. In an alternative embodiment, iron or iron oxide powder is agglomerated and sintered to provide porous spheres which are then coated with the other alloy constituents, and heated to above the melting point of lead to diffuse these metals into the iron agglomerates.

Title: Improvements in mine roof supports
Inventor: DAWSON GORDON BERTRAM
IPC: E21D23/00
Filed: 1962-03-09
Abstract: 1,037,174. Advancing mine roof supports. COAL INDUSTRY (PATENTS) Ltd. May 3, 1963 [March 9, 1962], No. 9200/62. Heading F1P. In a mine roof support system comprising a plurality of advanceable fluid pressure operated support frames extending along the working face of a mine and each including support props 2, at least some of the frames are each connected to a face conveyer (not shown) by a double-acting ram 17 which normally advances the conveyer towards the working face, but when extended a predetermined amount initiates the advance of its associated frame. Each frame has an associated valve box 16 connected by a branch line 28a to a pressure supply line 28 and by a conduit 32 to a return line 29. The valve box 16 comprises a two position valve 22 having ports 23-26 and a sliding piston 21, the position of which is determined by the extension of the ram 17. As shown the props 2 are supporting the roof, pressure fluid being supplied to the lower ends of each prop cylinder 2a through branch line 28a, conduit 30, port 26 and through each of four pressure operated non-return valves 34. Simultaneously pressure fluid passes from the port 26 through a further pressure operated non- return valve 35 to extend the ram 17 and thereby advance the conveyer. The ram contracting side of ram 17 and the upper ends of each prop cylinder 2a are connected through respective conduits 42, 41 and the port 24 with the return line 29. When the ram 17 is nearly completely extended a lost motion device 18, 20 associated therewith ceases to operate and the piston 21 is moved to the left, whereby, provided pressure operated non-return valves 33 are open, pressure fluid passes from the branch line 28a through port 25 to act on the pistons 34a, 35a of the pressure operated non-return valves 34, 35 and also passes to the conduits 41, 42 to pressurize the upper ends of the props 2 and contract the ram 17. The valves 34, 35 therefore open to allow fluid to pass from the ram 17 and the lower ends of the cylinders 2a through the port 23 to the return line 29. The non-return valves 33 are subjected, through conduits 39a, 40a to the pressure prevailing in the props of the two adjacent support frames whereby advance of a frame is prevented in the event of an adjacent frame being in a non-supporting condition. Contraction of the ram 17 advances the frame until the piston 21 is returned to its frame supporting position wherein conduits 39, 40 are pressurized thereby opening the valves 33 of the two adjacent frames to permit their subsequent advances. Pressure relief valves 36, 37 are provided. The valve 22 may be a rotary valve and the two valves 33 may be combined.

Abstract: 814,229. Applying ribs to insoles. PRIME MANUFACTURING CO. March 21, 1957 [Feb. 11, 1957], No. 9258/57. Class 17(1) In a machine for applying rib stripping to insoles 40, having means 12 for supporting an insole, a guide for guiding the stripping to the insole, and means 17 for pressing the stripping on to the insole and feeding the work so that the stripping is drawn through the guide and laid along the insole margin, the guide has a heating chamber which has between the stripping in the guide and the adjacent part of the insole, and has at least one inlet and at least one outlet permitting hot air to pass continuously through the chamber and impinge on the stripping and/or the part of the insole to which it is to be attached. The roll 12 supporting the sole 40 is freely rotatable on the pivoted arm 11 and is urged upwardly by spring 14 to co-operate with feeding feet 17, as in Fig. 1. The guide foot is angularly adjustable about the point 20, and its curved undersurface 19, which converges downwardly towards the bottom plate 23 and then extends parallel therewith, forms with plates 21, 22, 23, a passage which receives the strip in folded condition and presents it at point 20 with the flanges 42, 43 arranged perpendicular to the rib forming portion 41. Plate 23 and sole plate 26 form a hollow wedge-shaped chamber which receives heated air from the heating unit 30 via valve 35, and through perforations 24, 27, in this chamber heated air is directed against flange 43 and sole 40 to activate cement previously coated thereon. When arm 11 is moved downwardly to its inoperative position roll 12 is rendered inoperative so that feeding ceases, and rod 13 is lowered and via arm 37 moves valve 35 so that the heated air is discharged to the atmosphere. Toggle 16 holds arm 11 &c. in the inoperative position. The cement on flange 42 is activated as a result of movement of the flange in contact with or in close proximity to the heated guide part. Specification 716,921 is referred to.
Patent GB-820664-A (GB)
Title: Improvements relating to the conversion of aromatic hydroperoxides by cleavage into phenol and other products
Filed: 1957-03-21
Abstract: The invention comprises a method of detecting a potentially dangerous build-up of an aromatic hydroperoxide in the cleavage zone of a system for cleaving aromatic hydroperoxides into phenol and other products by cooling to below its boiling point a bleed stream from the cleavage zone, decomposing the hydroperoxide contained in it and measuring this heat of decomposition which is a measure of the hydroperoxide concentration in the bleed stream. The hydroperoxide mentioned is isopropylbenzene hydroperoxide which may be cleaved into acetone and phenol while minor quantities of acetaldehyde, acetophenone, mesityl oxide and alpha methyl styrene are also obtained.  A known fraction of the hydroperoxide is withdrawn from the cleavage vessel and is cooled to about 15-20 DEG  F. below its normal boiling point (about 168-170 DEG  F.).  The stream is passed at a constant flow rate and pressure over two resistance thermometers which measure its temperature T1.  It then passes into a mixing receptacle where sulphuric acid is pumped in at a known rate and on leaving the receptacle the temperature T2 of the mixture is measured with a resistance thermometer.  The difference in temperature T2-T1 = D T1 is due mainly to the heat of solution of the acid as the mixture does not remain in the mixing receptacle long enough for any appreciable decomposition of the hydroperoxide to occur.  The mixture passes to a second receptacle where it remains for about three minutes which is sufficient time for the decomposition to occur.  The exit temperature T3 is again measured on a resistance thermometer and the difference T3-T1 = D T2 is the heat of solution of the acid together with the heat of decomposition of the hydroperoxide.  The resistance thermometers may be made to activate various electrical circuits so that when D T2 or T3-T2 exceeds a predetermined value the supply of hydroperoxide and/or acid to the cleavage vessel is cut off automatically.  The reaction may also be stopped, if desired, when D T1 falls below a predetermined value as this indicates that the acid flow to the mixing vessel has been cut off and that D T2 is not a true reading.  The various steps of the invention are shown diagrammatically on a flow sheet.
