Filed: 1972-11-14
Abstract: 1351089 Refining copper INTERNATIONAL NICKEL CO OF CANADA Ltd 14 Nov 1972 [15 Nov 1971] 52569/72 Heading C7D Impure copper, e.g. cement copper, containing up to 5% iron, up to 10% oxygen, up to 1% sulphur and arsenic, bizmuth, lead, selenium, tellurium, tin and/or zinc, is refined by a process which comprises:- (a) Melting the copper while adjusting the oxygen content to ensure that there is sufficient to combine with all the sulphur as sulphur dioxide, but insufficient to form a separate cuprous oxide phase. (b) Removing any slag from the molten bath. (c) Passing a purge gas through the melt while maintaining a pressure less than 0À01 atmospheres. (d) Reducing the pressure to less than 0À0002 atmospheres without any purge gas. (e) Deoxidising the melt. (f) Casting. In order to adjust the oxygen content in step (a) the impure copper may be pelletized or briquetted with reducing agents e. g. fuel oil and then melted at 1250-1400 C. Iron oxide is removed in the slag at step (b). Step (c) involves desulphurisation by passing a purge gas e.g. nitrogen, argon, air carbon dioxide or oxygen through the melt at pressures preferably between 0À001 and 0À0002 atmospheres, which assists removal of sulphur as sulphur dioxide. The reduction of pressure, preferably to below 0À0001 atmoshperes, in step (d) eliminates other volatile impurities while mechanically or inductively agitating the melt. Deoxidation in step (f) may be accomplished with a reducing gas e.g. hydrogen, carbon monoxide, natural gas or propane until oxygen content is below 0À05% and then with granular carbon while agitating with nitrogen or argon under pressures of less than 0À01 atmospheres. Optionally, complete deoxidation can be accomplished with phosphorus.

Filed: 1969-11-18
Abstract: 1,242,178. Sheet-delivering apparatus. ADDRESSOGRAPH MULTIGRAPH CORP. 18 Nov., 1969 [27 Nov., 1968], No. 56442/69. Heading B8R. Sheets are delivered from a machine such as a lithographic printing machine along a first path and deflector means are movable along that path to a selected station position to divert the sheets at that station from the first path. General arrangement.-Sheets from a delivery shoot 20 pass on to the uppermost run of an endless continuously moving conveyer 12 passing around fixed axis guide rollers 13 and rollers 14, 15 on a horizontally movable carriage 16. A deflector 19 on the carriage 16 diverts sheets towards a series of receivers 17. The carriage 16 during its movement from right to left, Fig. 1, can be controlled so as to stop opposite a selected receiver 17 and deliver a predetermined number of sheets to that receiver and then move leftwardly to a next selected receiver and deliver a predetermined number of sheets to that receiver, and so on. The carriage 16 is returned to the right at the completion of a right-to-left tra. verse. A slow moving belt 26 adjacent the bottom of the receivers 17 moves the sheets in the receivers rightwardly to secure unobstructed entry of sheets into the receivers. The deflector 19 can be turned manually into a horizontal position to that all sheets pass to a by-pass receiver 21. Detailed description.-The carriage 16 has supporting rollers 31 running on tracks 30. A pivoted arm 36 on the carriage is urged by a spring (64, Fig. 6) to a position where its lower end engages a notch 41 in a fixed rail to hold the carriage adjacent one of the receivers 17. Actuation of a solenoid 63 however pivots the arm 36 so that it disengages from the notch 41 and engages the teeth of a sprocket 35 fixed to the conveyer roller 15 whereupon the carriage is moved leftwardly by the conveyer. A normally open switch 61 actuating the solenoid 63 is closed by the engagement of its actuator with a rail 65 having an opening 66 adjacent to each receiver, so that if an opening is unimpeded, the switch opens at that point and the carriage 16 stops. Adjacent to each opening 66 is a settable dial 44 of a sheet-counting device, each dial having a cam part 60 which, in the zero position of the dial, projects into an opening 66. When the dial 44 of a particular receiver 17 is set at a given number, the cam 60 is moved away from the opening so that when the carriage 16 reaches that receiver, the switch 61 is opened and the carriage stopped. Sheets now pass over the deflector 19 into the receiver, and as they do so, actuate a switch 55 and cause a ratchet mechanism to move the dial 44 step-by-step back to its zero position, whereupon with the required number of sheets delivered to the receiver, the cam 60 actuates the switch 61 to cause the carriage 16 to move leftwardly until it reaches another receiver whose dial 44 has been set for delivery of a given number of sheets. For collating, each dial is set at one, so that one sheet is delivered to each pocket.

Abstract: 1,148,699. Telegraphy; automatic phase control. CREED & CO. Ltd. 15 Dec., 1967 [22 Dec., 1966], No. 56997/67. Headings H3A and H4P. A telegraph receiver which can receive signals at various or varying bit rates and pass the signals to an output device which has a fixed cycle time, e.g. a printer 15, includes a serialparallel converter 2 fed by the received signals and having a cycle time manually or automatically adjustable in dependence on the signal speed. Each serial Start-Stop signal at la is fed to converter 2, and the Start bit starts clock pulse generator 4 via unit 3. Generator 4 stops when the converter has cycled once. Centrescanning clock pulses at rate b on line 4a control read-in to the converter, and on 4b pulses at rate 8b are fed to unit 8 which enables the eight gates 9 sequentially and repeatedly. Bittransitions in the received signal are detected by differentiation at 5, the resultant pulses passing via rectifier 6 to each of the gates 9. If the generator is developing clock pulses at the frequency of the received bits a transition pulse will be present each time gate 9/1 is enabled, lamp L1 indicates this. However, if the frequency is not the same, or if the bit-rate varies, one or more of the remaining gates 9 will be enabled at the transition instants, if gates 9/2- 9/4 or 9/6-9/8 produce pulses unit 13 automatically adjusts the generator frequency towards that of the received bits. Alternatively, inspection of the lamps fed by the gates indicates when the generator frequency is too high or too low, the generator then being adjusted manually.

Abstract: 1,247,195. Automatic roll stabilization. ASSOCIATION DES OUVRIERS EN INSTRUMENTS DE PRECISION. Dec. 4, 1968 [Dec.29, 19671, No. 57616/68. Heading G3R. Anti-roll torque applied to a ship is automatically controlled by opposed electrical contacts operated by relative movement between a pendulum and a balanced member movable with greater frictional resistance about a longitudinal axis of the ship. In Fig. 9, angle of roll of a ship is detected by potentiometers 30, 31, adjusted by a pitch-compensated pendulum pivotted about a longitudinal axis, and the instants at which roll attitude reaches a maximum are detected by the change-over of pendulum-operated contact 23 relative to contacts 21 1 , 21 2  carried by a balanced member 20 which is movable against light friction about the longitudinal axis. Pulses produced by the contact change-over cause operation of relays to store transistor amplified signals picked off from the pendulum operated potentiometers in a capacitor unit MI, Fig. 7. From the stored signals, a signal -# M , corresponding to the mean list attitude of the ship, is developed and applied to differential relays AS which periodically control valves FB, FT and thus the venting or coupling to compressed air to list stabilizing tanks 2B 2 , 2T 2  arranged below the water line on each side of the ship so that water enters and leaves them in such a manner as to oppose listing of the ship. Followup signals VB, VT from float operated potentiometers in tanks 2B 2 , 2T 2  are fed back to relays AS. Further signals # N , corresponding to the amplitude of roll, are developed from the stored signals in unit MI and applied to adjustable gain transistor circuits CaB, CaT having resistancecapacity circuits which determine the times of periodic operation of valves EB, ET controlling the filling and emptying of further, roll, stabilizing tanks 2B, 2T, which oppose roll of the ship. Systems not utilizing a signal dependent on the mean list attitude of the ship, systems using a gyroscope instead of a pendulum, and systems involving the control of stabilizing fins of variable incidence, length, or time of extension, instead of stabilizing tanks, are referred to.
