Title: Improvements in or relating to the production of strip material
IPC: B22D11/06
Filed: 1951-11-08
Abstract: 768,160. Spraying metals. BRENNAN J. B. Nov. 8, 1951, No. 24949/54. Class 82(2). [Also in Group XXIX] Molten material is fed at constant pressure through spray means on to a constant speed moving base on which it coalesces and solidifies in to a coherent strip. Molten metal from a crucible or tank 11 passes through an outlet 15 into an extension spout 12 and thence to a spray nozzle 25. The outlet 15 is controlled by a gate valve 16 operated by a float 18 to keep the metal in the spout 12 at constant level. Should the metal in the spout fall below a predetermined level, the opening to the nozzle is closed by a counterweighted float 20. The crucible or tank 11 is covered by an inverted container 13 in which is a manually operable storage ladle 22 which can be recharged through the trap 24. Atomizing gas is supplied to the nozzle 25 through the tube 27; induction heating coils 29, 31 are provided around the container 13 and nozzle 25, A receptacle 33 receives overflowing metal from the spout 12, a pump forcing it back in to the container 13. Spraying is effected in the chamber 10a which is evacuated by the pump 36. Metal is sprayed on to a backing strip 37 which passes from roll 38 to roll 39 and may be of porous paper or stainless steel; in the latter case, the sprayed strip is detached from the backing and passes through rollers 43, 44 to the roll 45. A paper backing strip may be removed by burning. The temperature of the spray is controlled by the induction heated funnel 41 and the backing strip may be heated or cooled e.g. by a cooling shoe 100 through which water is circulated Endless bands 104, 105 prevent deposition of metal along the edges of the backing strip. The sprayed material may be aluminium. Reference has been directed by the Comptroller to Specification 735,695.

Title: Improvements in the treatment of pyrites and like sulphide ores to recover sulphur therefrom
IPC: C01B17/06
Filed: 1933-09-13
Abstract: <PICT:0425365/III/1> In the production of sulphur from iron sulphide ores by the action of sulphur dioxide thereon, fusion of the ore is prevented and the use of temperatures of 1200 to 1400 DEG  C., is rendered possible by treating a mixture containing silica and iron sulphide in about molecular proportions.  The mixture is obtained by adding silica to the ore, or where the ore contains excess of silica, removing silica, e.g. by flotation.  Inert gases, e.g. nitrogen, may be mixed with the sulphur dioxide, and oxygen, either as such or as air, may be added together with carbon, e.g. coke, to produce the temperature required.  As shown, sulphur dioxide and air enter a rotary furnace 1 by a pipe 4, the gases being preheated by the descending solid reaction products which may be discharged at a pit 6 formed in the end wall 2 of the furnace.  As the gases pass upward they meet the sulphide ore which is either oxidized to ferrous oxide and sulphur dioxide or reduced to ferrous oxide with the formation of elementary sulphur.  The gases, consisting of nitrogen, sulphur vapour and sulphur dioxide, pass by tube 5 to a dust-removing apparatus 10 and thence to a sulphur precipitator 11 after which the gases pass to a plant 13 where the sulphur dioxide is concentrated and in which the solvents described in Specifications 400,998 and 419,068 may be used.  A portion of the gases may be byepassed by a pipe 15 connected to a pipe 14 which conveys the concentrated sulphur dioxide and the byepassed gases to pipe 4.

Patent GB-795003-A (GB)
Title: Improvements in or relating to accounting machines
IPC: G06F7/00
Filed: 1955-09-06
Abstract: 795,003. Calculating-apparatus. ELDIFEINMECHANIK GES. Sept. 6, 1955 [Oct. 6, 1954], No. 25489/55. Class 106 (1). An accounting machine having input, calculating and printing means has two storage units each including a calculating store (a store from which information is transmitted to the calculating means) and a printing store (one from which information is transmitted to the printing means) and being so connected and controlled that when the stores of either unit are both coupled to the input means, the stores of the other unit are respectively coupled to the calculating and printing means. Thus no time is wasted during the input of information. The invention may be applied to a machine having similar stores, calculating mechanism, and datatransmission arrangements to those described in Specification 785,285. On depression of a digit key 4, contacts 19 are closed to cause the corresponding digit to be entered, initially, in calculating and printing stores 11, 13 forming a first unit, over unoperated contacts 9a of a relay 9. A control key 3 is then depressed to close contacts 22 so as to energize a relay 8 arranged to cause the machine to cycle. This relay is latched until released by a magnet at the end of the cycle. Depression of the key 3 also changes over contacts 21 which energize a winding 9I of the relay 9, and on release of the key 3, the relay 9 remains operative due to the energization of a winding 9II in series with a relay 10. Change-over contacts 9a, 9b and 9c thus remain in operated positions to enable the information to be read from the stores 11, 13 and to enable fresh, information to be entered simultaneously into calculating and printing stores 12, 14 forming the second unit. When the control key 3 is next depressed, the relay 9 becomes inoperative due to contacts 10a of relay 10, and on release of the key 3, the relay 10 also becomes inoperative. Thus, the stores 12, 14 are able to transmit information, and the stores 11, 13 are once more connected to receive information. Information in the printing stores is transmitted to magnets 6 controlling type bars 5, and that from the calculating stores is transmitted to line and column calculating mechanism 16, 15 into which other factors are simultaneously fed from stores 18, 17. A line or column total may be printed under the control of paper-carriage-operated contacts 23 or 24 by transmitting the total to the receiving storage unit and then printing the amount at the next stage.

Title: Improvements in or relating to apparatus for handling nuclear reactor fuel elements
Inventor: CHALLENDER RONALD SCOTT
IPC: G21C19/36
Filed: 1956-08-22
Abstract: 814,996. Broaching; breaking. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 22, 1957 [Aug. 22, 1956], No. 25613/56. Classes 83 (3) and 83 (4). Apparatus for cutting away the sheath 28 from a nuclear-reactor fuel element comprises an annular cutting die 11 and means 70 for preventing bowing of the element as it is passed through the die. The element is initially supported by V-guides 21 which are raised by a rod 64 engaging a lever 63. When a crosshead 31 is advanced by a fluid-pressure ram 43, it moves a centre 30 up to one end of the element and moves the other end of the element against a spring-pressed recessed centre 29 which projects through the fixed die 11. The bowpreventing rollers 70 are then forced against the sheath by fluid pressure means 69, and the V-guides 21 are withdrawn. As the ram 43 advances further, the cross-head 31 engages shoulders 38 on rods 19 connected to a crosshead 36 carrying the centre 29, and the crossheads 31, 36 advance together with the element. When the end cap 33 has been sheared through, the rollers 70 are withdrawn and the element passes completely through the die. At the end of its stroke the cross-head 36 breaks into four pieces a previously stripped fuel-rod, resting in slots 62 in the machine frame, by projections 55 co-operating with a fixed abutment 60. Prior to this, a fixed cam strikes a lever engaging a slot 53 in the centre 29, thus releasing the fuel rod. When the cross-head 31 is returned, the last part of its movement causes the centre 30 to be drawn through a stripper crosshead 45 to remove the cut cap 35. The fuel rod is picked up with tongs and placed in the slots 62 for breaking. The broken fuel rod is removed to an extraction plant. The whole process is carried out under water, and the machine parts are chromium plated or aluminium sprayed to prevent corrosion.
