Abstract: 1,252,065. Recovering copper. ETHYL CORP. March 21, 1969 [March 28, 1968], No. 14894/69. Heading C7D. An aqueous ammoniacal solution containing Cu together with Ni and/or Mn is contacted with CO to reduce the Cu to metal. The Ni or Mn carbonyl which promotes the reduction of the Cu ion may be formed in situ or may be initially present in the solution. The carbonyls are preferably taken up by a solvent. The solution may also be seeded with finely-divided Cu. The solution may be made ammoniacal by introduction of NH 3  gas or by preparing it with aqueous NH 4 OH. Suitable metal anious are sulphate, sulphite, chloride, bromide, carbonate and nitrate. When the metals are introduced as sulphides, the solution is treated with air. Reference is made to the separation of Ni, Co, Cu, Fe and precious metals from e.g. sulphide ores containing these metals. The CO, which may be introduced in admixture with H 2 , may be under a pressure of 200-1200psig. The reaction temperature may be 100‹-250‹ C.

Abstract: 1,256,563. Cine cameras. NIPPON KOGAKU K.K. Feb.20, 1969 [Feb.23, 1968], No.9269/69. Heading G2E. A cine camera using a cartridge 1 with no feed spool shaft operable from outside has a winding mechanism which permits re-winding and double exposures for dissolves and comprises a film take-up spool drive selectively operable in driving and non-driving modes, and a stop mechanism which automatically stops forward drive at a predetermined time after the take-up drive has been placed to the non-driving mode, and which, following operation of the drive in the reverse direction, automatically stops reverse drive after a further predetermined time. The film take-up shaft gear 11 is driven by a worm 4 on main shaft 3 reversibly rotated by motor 8, an intermediate idler gear 12 being movable by clutch lever 15 to disconnect to drive to gear 11. During normal exposure, N, if control knob 27 is set to F, cam 19 shifts lever 15 to de-clutch gear 11 and to engage gear 14 with a counter gear 26, the end 21 of lever 15 being lifted from a notch 24 in counter disc 23 which is now driven. Film is stored loosely in the cartridge 1 until a pin 34 on gear 26 shifts a stop member 30 to engage a lug on disc 5 and so to stop shaft 3. With knob 27 set to B, the loose film is re-wound and lever 15 re-enters notch 24, cam 42 reversing motor 8. An inter-lock system prevents normal running N until the rewind step has been completed.

The rotation of the leaders 9 in the pipes 2 and 3 is initiated by a nylon brush on the inside of each pipe which engages the hooks 10, the rotation thereafter being maintained by centrifugal force on the hooks and their friction with the pipe interior. The hooks are guided along the whole length of the final pipe 4 whose speed is related to the speed of hauling of the long line 8 such that the leaders 9 are fully unwound as they exit from the pipe 4. The pipes 2, 3, 4 may have a circular cross-section, or triangular to facilitate better control over the hook movement. In another embodiment, the three pipes are set in parallel and therefore all rotate in the same direction to achieve the same result.

Abstract: 1322900 Prepayment mechanisms UNITED GAS INDUSTRIES Ltd 14 Oct 1970 [15 Oct 1969] 50570/69 Heading G4V A rotary coin holder mechanism 7, for use in a prepayment unit 1, includes a pocket 8, for receiving a coin of either of two values, having pivotally mounted thereon a striker member 38 carrying two strikers 17, 18 which can be selectively disposed into respective rotary drivetransmitting positions by pivoting of the striker member in opposite respective directions, and an actuating member 24 displaceable by the insertion of a coin of a first diameter to pivot the striker member in one direction and by a second coin to pivot the striker member in the other direction. In the embodiment described a coin is inserted between a fixed guide member 25 and the actuating member 24 which has a flank portion 27 carrying two posts sliding in parallel slots in plate 22 (Fig. 7, not shown) controlling the movement of the actuating member. One post 28, sliding in slot 29 engages a slot 30 in pivoted lever 31 that is biased anticlockwise by a spring 33. A post 36 mounted on the lever 31 engages the pivoted striker member by means of a slot 37 which is shaped so that an initial rotation of the lever pivots the striker member in one direction while a further rotation of the lever pivots the striker member in the other direction (see also Figs. 4 to 6, not shown). On the insertion of the smaller coin striker 17 engages quantity wheel 13 whereas the larger coin causes striker 18 to engage both quantity wheels 13, 14. On rotation of the coin holder mechanism by handle 12 a dial 5 prepayment meter 2 is driven through differential gear 15 and gearing 16, the transmission ratio being determined by whether one or both quantity wheels is engaged by a striker. The initial position of the coin holder mechanism is determined by the location of a stud 20 in a price-change wheel 9 (see also Fig. 1, not shown). An extension 20a of the stud engages a projecting tongue 21d on a hinged side plate 21a of the coin pocket and allows the coin to fall from the pocket. As the commodity purchased is consumed a shaft 4 is driven which causes the dial 5 to rotate, a fixed pointer (6) indicating the amount left at any time. When prepayment has been made for a maximum allowable quantity a cam 40 engages a stop lever 41 and moves it into engagement with a lug 42 formed on the striker member and prevents it returning from an operative position, and through a pawl on the lever plate 31 stops return rotation to the initial position.

The drive means for the cutting head comprises a fixed cylinder 9 and a ram supporting a pair of gear-wheels 12 which engage fixed racks 4 on the shear base and a rack 13 on the underside of the head. A power driven screw may replace the ram. Thelower cutter 20 is driven via reduction gearing by a pinion 22 engaging a rack 5 on a side wall 3 of the shear frame. Plates (18), Fig. 1 (not shown), at the mouth of each slot guide the severed portion and the strip stock into the slots 15. The cutting head is supported on a plate 7 which has edge flanges engaging flanges 8 on the side walls 3. Associated with each cutter disc is a shoe plate 29, Fig. 6, which has dogs 31 spring loaded to urge serrated faces 32 against the strip, the dogs of each cutter disc being opposed to the other cutter disc to draw the strip through the cutters. One cutter may be movable transversely relative to the other to provide for different thicknesses of strip to be sheared. A pneumatically actuated clamping bar (25), Fig. 1 (not shown) in front of the shear co-operates with a support roll (23).

Upon playback the signals are fed via inputs 19 and 20 of the adaptor, a modulator 21 and signal splitter 8 to output 9 for display on the receiver 4. The signal being recorded may be different from that received by the receiver 4. The signal being recorded may be monitored on the receiver 4 by tuning the receiver to the modulated signal from modulator 21, there being a direct connection being amplifiers 12 and the modulator 21. An aerial trap 7 is included to prevent radiation of the modulated signals provided by modulator 21. During playback of the recorded signals a D.C. signal from the recorder actuates a relay 24 in the adaptor which renders tuner 10 and stages 11 inoperative by disconnecting their power supplies. This prevents the played back signals forming a closed loop if the tuner 10 happens to be tuned to the modulation frequency of modulator 21. The video frequency output of a television camera may be applied to the input or output of vision amplifier 12.
