Abstract: 665,911. Punching. PARNALL (YATE), Ltd. June 27, 1949 [June 8, 1948], No. 15439/48. Class 83 (iv). Punches.-In apparatus for punching holes in tubes for gas burners &c. the tube is positioned on a recessed block 1 mounted on a carriage 6. A multiple punch unit 8 is supported in a frame 9 spring- mounted on pillars 11 and carries grooves on the underside which co-operate with similar grooves on the block 1 to engage transverse parts of the tube. To effect the punching in two stages one half of the holes are punched in a first operation and the work-holder is then moved and the rest of the holes are punched. The punch head 26 and the punch carrier are connected by a positioning device comprising a member 28 pivoted to the head 26 and cams 30, 31 on the frame of the punch carrier which co-operate with a roller 33 on a lever 29 journalled in the member 28. The punch head 26 carries spring-mounted pads 27 which on the descent of the head contact and depress frame members to clamp the tube. The roller 33 engages the cam 30 to push the punch unit 8 to a side position and a pilot bar 37 engages an aperture 36 in the carriage 6 to hold it in position. The punch unit comprises punches 15 slidable in sleeves 16 positioned by springs 19, 20. The punches are held normally retracted within the sleeve 16 but light pressure on the punch projects the sleeve 16 to straddle and hold the tube. Further lowering of the punch head through a plate 25 comprises the springs 19, 20 and effects the first punching operation. The head is raised and the roller 33 closes the cam. On the next descent the roller 33 engages the cam 31 and the punch carrier is moved to the other extreme position and the second punching operation is effected.

Title: Dephosphorization of melts of ferrous metals
IPC: C21C1/02
Filed: 1961-05-02
Abstract: A phosphorus bearing pig iron, cast iron or steel melt is dephosphorized without loss of carbon by a method comprising forming on the melt a molten basic slag layer containing at least one constituent known to dephosphorize iron such as lime and iron oxide together with fluxing agents, the temperature of the melt being not more than 200  DEG C. above its solidification temperature, continuously supplying oxygen and feeding a solid oxidizing, basic slag-forming mixture containing the reactive constituent to the melt, either to the surface or below the surface thereof, and simultaneously withdrawing slag from the layer.  Preferably the slag-forming mixture, which may be granular, powdered or compacted into rods, is fed to the same area of the layer to which the oxygen is supplied and wherein the temperature is higher. For example, at least a portion of this mixture may be powdered and blown with the oxygen on to or below the slag surface.  The oxygen is preferably supplied at a constant rate through a forked lance (see Division F4) and only the rate of feeding of the mixture varied.  Slag from the later stages of treatment may be cooled, comminuted and recycled by admixing to the slag-forming mixture. The melt may be contained within a basic, neutral or an acid lined container such as a ladle which is tilted for the continuous removal of slag. An example of a slag-forming mixture is:  33% rolling scale, 27% burnt lime, 24% blast furnace flue dust, 13% soda ash and/or glass waste, and 3% fluorspar.

Abstract: 504,680. Thermionic distributers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 27, 1938, No. 15939. Convention date, May 28, 1937. [Class 40 (v)] A circuit arrangement for sequentially operating a number of switches 10, 13, 16 to connect sources 01, 02, 03, to a recorder 1, comprises a number of valves 18, 19, 20 with relays 34, 36, 41 in their anode circuits. Normally, all valves are blocked by negative bias through high resistance grid leaks. On momentarily closing contacts 49, condenser 47 is discharged and valve 20 passes current. Relay 41 operates to connect 03 to the device 1 and simultaneously condenser 58 is disconnected by switch arm 57 from the grid of valve 18 and discharged. After a period of time determined by the combination of resistance 43 and condenser 47, valve 20 again becomes, blocked and releases relay 41. The discharged condenser 58 is then connected to the grid of valve 18 which as a result becomes unblocked and actuates relay 34. In like manner the subsequent blocking of valve 18 and release of relay 34 by the slow charge of condenser 58 causes valve 19 to become conductive, which in turn controls valve 20 by means of relay 36. The cycle of operations, once initiated, continues to repeat itself. Specification 483,740 is referred to.

Title: Improvements in or relating to the separation of nickel
IPC: C01G53/00
Filed: 1956-05-23
Abstract: Nickel is separated from an aqueous solution containing nickel and cobalt salts by contacting the solution with a couple consisting of a metal more electronegative than nickel (e.g. iron) and an arsenical and/or sulpho-arsenical ore of Co and Ni which in the solution is more electropositive than Ni (e.g. smaltine) so as to precipitate the Ni; maintaining a pH low enough (e.g. 1-4) to keep co-precipitation of Co to a minimum; separating the insoluble materials from the resulting suspension; and treating them to dissolve substantially only the precipitated Ni.  Preferably the precipitation is effected at 70 DEG C. or above; the materials forming the couple are added in powdered state, the arsenical &c. ore having been pre-treated with acid to remove any oxidized elements and carbonates; copper in quantity at least 1/50th that of the electronegative metal is also added to the solution in the form of a soluble salt to act as accelerator; and a capric or ferric salt solution is used to dissolve the precipitated Ni, the ferric salt when used being preferably in less than stoichiometric amount but being regenerated by e.g. chlorine or oxygen and re-cycled.  The arsenical &c. ore from which the precipitated Ni has been removed, optionally mixed with calcined ore of the same type, may be treated with acid to produce a new starting solution of nickel and cobalt salts.  The Specification also refers to the use of iron powder alone for precipitating nickel at a greater rate than cobalt from a solution of Ni and Co salts; and also to the improvement of adding together with the iron an element (e.g. copper). more electropositive than nickel to serve as accelerator.
