Title: A method for the production of metal powders and welding electrodes containing such powders
IPC: B22F9/04
Filed: 1953-09-04
Abstract: Powders are manufactured from low carbon iron-chromium alloys by treating such an alloy, having a composition making it sensitive to sigma-phase formation, within a temperature range in which transformation to the sigmaphase occurs, preferably 600 DEG -800 DEG C., for such a period of time as to effect said sigma-phase formation, whereby the alloy is rendered brittle, and crushing and/or grinding the brittle alloy to powder.  The alloys may be heated up to a temperature in said temperature range or alternatively, the alloys, already at a temperature above the range, e.g. in the molten state, may be slowly cooled through the range.  They preferably have a carbon content of less than 0-20 per cent, a chromium content of 20-60 per cent, preferably contain at least 1 per cent silicon and may contain, in combination with silicon, the following metals, either alone or in combination with each other: Ni, Ti, Zr, Nb, Ta, V, Mo, W, Mn, Cu, Al and Co.  The following are the compositions of alloys given by way of example, the remainder in each case consisting of iron and carbon together with the usual impurities: (i) Cr 51 per cent and cent (iii) Cr 47 per cent and Ni 12 per cent (iv) Cr 47 per cent, Ni 19 per cent and Mo 4 per cent (v) Cr 43 per cent, Ni 19 per cent, Mo 5 per cent and Cu 4 per cent (vi) Cr 43 per cent, Ni 21 per cent, Ti 2 per cent, Nb 4 per cent and Ta 1 per cent (vii) Cr 44 per cent, Ni 18 per cent, Mo 6 per cent and Cu 8 per cent (viii) Cr 45 per cent, Al 12 per cent, Si 8 per cent and Co 12 per cent (ix) Cr 35 per cent, Ti 5 per cent and Co 45 per cent (x) Cr 46 per cent, Al 10 per cent, Si 4 per cent and Zr 2 per cent (xi) Cr 40 per cent, Ni 2 per cent and Mn 40 per cent (xii) Cr 43 per cent, Ni 21 per cent, V 1 per cent, Si 3 per cent, W 4 per cent and Nb 4 per cent. The powder may be (a) incorporated in the slag-forming portion of a welding electrode (b) used in the manufacture of sintered stainless steel parts and (c) used in the manufacture of tough low carbon iron-chromium alloys when it is mixed with other alloying ingredients, in such amount that susceptibility to sigma-phase formation disappears when the mixture is melted, and the mixture is melted so that the sigma-phase disappears and a tough homogeneous alloy is formed.

Title: Improvements in or relating to valves for the control of fluids
Inventor: SHAND STANLEY GRAPES
IPC: F15B13/08
Filed: 1959-07-16
Abstract: 961,537. Controlling lifting jacks. SAUNDERS VALVE CO. Ltd. July 18, 1960 [July 16, 1959; Feb. 11, 1960], Nos. 24511/59 and 4932/60. Heading B8J. The invention relates to a valve assembly for controlling the supply of pressure fluid to jacks acting on a mine roof support, and the supply of pressure fluid to a ram for moving the jacks and a ram for moving a conveyer extending between the jacks. When a valve 1 is in its normal position, control pressure fluid can pass from an inlet 16 via a port 15 in the valve 1 and passages 17, 48, 49, 51 so as to act of the left-hand end of a plunger 47 so as to maintain three further valves 2, 3, 4, in the positions shown. The valves 2, 3 in this position permit pressure fluid to pass from an inlet 23 to outlets 24 leading to the jacks (Figs. 5-7, not shown). Pressure fluid in the outlets 24 acts through a port 28 so as to open a trip valve 18 which connects the passage 48 (and thereby the control inlet 16) to an outlet 33 which is connected to the control inlet of a valve assembly associated with an adjacent set of jacks. Pressure also acts from the outlets 24 on a plunger 37 which thereby maintains open a valve 38 which permits pressure fluid from an inlet 44 to pass through the valve 4 to an outlet 43 leading to a ram (Figs. 5 and 7, not shown), for advancing the conveyer. When the latter has advanced to a predetermined degree, a stop which it carries disengages from the right-hand end of a plunger 8 (Fig. 4), so that the latter is displaced by a spring 12 to actuate a rack 7 and so rotate a pinion 5 coupled to the valve 1. This results in the control inlet 16 being connected by a port 19 in the valve 1 with a port 46 leading to a differential piston surface of the plunger 47. The plunger is deflected and thus rotates the valves 2-4 through 45 degrees. Ports 56 in the valves 2, 3 connect the outlets 24 to the jacks, to an annular space surrounding the respective valves, and which are connected to an hydraulic return line outlet RL. The inlet 23 is closed by the valves 2, 3 but is opened by the valve 4 to connect with an outlet 61 leading to the ram which advances the jacks. So that the conveyer ram will not prevent the action of the jack ram the former is connected via outlet 43 passage 42, and port 62 in valve 4, with the return line RL. The valves 2-4 may each be turned manually by a member 63 which is lifted against a spring 64 to disengage the valve from its connection with the plunger 47.

Title: The manufacture of wool-like artificial fibres
IPC: D01F11/02
Filed: 1934-08-31
Abstract: Wool-like artificial fibres are manufactured by carrying out the desulphurization of viscose material, and the after-treatment with organic liquids capable of dissolving water according to Specification 424,229 by a treatment with the said organic liquids capable of dissolving water in the presence of a volatile base which boils below 100 DEG  C.  Advantageously the material is treated in a plurality of baths of increasing strength as regards the said organic liquids, and small quantities of volatile base, for instance ammonia, are added to the first bath of lowest strength. In an example a suitable viscose material is washed with water and squeezed to remove excess liquid.  It is then treated with a bath containing 35 per cent of ethyl alcohol and 1 to 10 per cent of ammonia, and subsequently with further baths containing more alcohol but no ammonia.  After the last bath consisting, e.g. of alcohol of 92 per cent strength, the adherent solvent is removed by squeezing or centrifuging and the residual alcohol recovered in known manner.  The baths may be connected by overflow apparatus, the alcohol running through the baths in countercurrent to the fibrous material, and ammonia being added to the last bath.
