Abstract: 1,014,496. Photographic cameras. FRANKE & HEIDECKE G.m.b.H. [trading as RALLEIWESKE FRANKE-HEIDECKE]. Oct. 4, 1962 [Oct. 12, 1961; Oct. 14, 1961], No. 37587/62. Heading G2A. A photographic camera comprises a feeler member which scans an exposure meter's galvanometer pointer and is controlled by a movable cam complete exposure setting main, the feeler being adapted to arrest the cam when it engages the pointer. In the embodiment shown the shutter speed is controlled by cam 36 and ring 37, the diaphragm aperture by ring 5 which is link to means to explore exposure meter pointer 18 and the shutter is released by rotation of ring 16. If when the camera is set and a spring 2 tensioned lever 3 is rotated clockwise, lever 10 on ring 1 is released and ring 1 together with ring 5, (through spring 11 and lug 12) rotate anticlockwise thereby adjusting the diaphragm. Simultaneously cam 6, through follower 23 rotates lever 19 about a pivot 20 until stop member 17 abuts pointer 18, the cam follower 23 then causes spring 22 to urge pawl 25 into engagement with teeth 7 and lock diaphragm setting ring 5. At one moment during rotation of ring 5 a pawl 33 pivoted on a bar 32 on ring 5 is rotated, by means of a stop in cam 36 into engagement with teeth 38 on a shutter speed setting adjusting ring 37; the position of the cam stop and hence the distance adjusting ring 37 rotates depends on the setting of shutter speed ring 35. When ring 5 has been locked by pawl 25 pawl 14 abuts a pin 29 on it and is rotated into engagement with teeth on shutter ring 16 so that as ring 1 continues to rotate ring 16 rotates also to operate the shutter. For manual control a latch 46 is disengaged from the control knob 45 and turned to short circuit the meter 41, the knob may then be turned to give the required aperture as shown on the disc 44.

Title: A method and apparatus for controlling the roasting temperature of ore
Inventor: GRIMES G R
IPC: C22B1/04
Filed: 1970-08-04
Abstract: 1,263,419. Multiple hearth furnaces; controlling hearth temperatures. AMERICAN METAL CLIMAX Inc. 4 Aug., 1970 [22 Sept., 1969], No. 37614/70. Heading F4B. [Also in Division C1] The oxidation roasting of sulphide ore concentrates e.g. iron sulphide, copper sulphide, zinc sulphide, nickel sulphide or molybdenum sulphide in a multiple hearth furnace is controlled by supplying to individual hearths a spray mixture of water and air under pressure, temperature measurement in each of said hearths being utilized to vary either the air pressure or the water pressure to restore a desired temperature in said hearth. Either of two control systems may be used, one (Embodiment A, Fig. 7) in which the spray cooling control system uses a variable air pressure and a constant water pressure, and the other (Embodiment B, Fig. 8) in which a constant air pressure and a variable water pressure is used. With the first system if the hearth temperature rises unduly the air pressure and therefore the air flow is decreased, reducing the heat developed, and consequential increased water flow increases the amount of heat dissipated. With the second system an increased hearth temperature results in an increased water pressure, an increased flow of water to the hearth and therefore a lowering of the temperature. With both systems as the hearth temperature falls below the desired temperature, the reverse action occurs. Using a twelve hearth furnace, Fig. 1, and numbering the hearths from the top downwardly it is usually sufficient to control hearths 2-7 or 2-8. The furnace 10, Fig. 1, comprises a refractory shell 11 with hearths 13 apertured centrally for a hollow rotary shaft 14 driven by a motor 18 through bevel gears 16 and 17 and supplied with air at 20 for distribution through rabble arms 21 over the hearths. Material (e.g. MoS 2 ) fed in at the top is discharged from alternate hearths 13 at the centre of the periphery by the rabble arms, said material leaving at 22. SO 2  is discharged with waste gases through a flue 23. As shown in Fig. 6 three pressure nozzles 27A, 27B and 27C are disposed symmetrically around the periphery of a hearth 13D and supplied with water and air through pipes 28 and 29. Rakes 31 on the rabble arms 21 are angled to feed the ore to the inside or the periphery of alternate hearths and work doors 30 are provided in the wall 11.
