Title: Treatment of metal sulphide-bearing materials
IPC: C01B17/06
Filed: 1930-09-23
Abstract: <PICT:0368289/III/1> Sulphide-bearing materials, especially ferrous sulphide or blende, are treated with hydrogen chloride to obtain hydrogen sulphide and metal chlorides, and the latter are subjected to the action of water vapour in the absence of air to obtain metallic oxides and hydrogen chloride for re-use.  Ferrous sulphide for use in the process may be obtained by treating pyrites with metallic iron, or with water vapour at elevated temperatures; or by heating in the presence of oxygen, in which case the sulphur dioxide also obtained may be reacted with the hydrogen sulphide produced in the first step of the process to obtain sulphur.  As shown, aqueous hydrochloric acid and ferrous sulphide are reacted in a vat 5, hydrogen sulphide passing off at 7 and ferrous chloride solution being passed direct or through a filter 9 to a closed evaporator 11 fitted with a conveyer 12 and heated by a furnace 14 so that the upper end is at a temperature of 240 DEG  C.  Water is released from the ferrous chloride in the lower end of the evaporator, and as the temperature rises the water vapour produced decomposes the chloride with formation of ferrous oxide which is discharged at 16 and hydrochloric acid which with excess of water vapour passes off at 17 and is returned direct or through a condenser 19 to the vat 5. Reference has been directed by the Comptroller to Specifications 2715/82 and 17834/97, [both in Class 1, Acids, alkalies &c.].

Abstract: 1342572 Manufacturing film units POLAROID CORP 18 June 1971 [18 June 1970 20 April 1971] 28784/71 Heading G2A Photographic film units are made by a continuous process of adhering a sheet of photosensitive material across the frame opening 28 in a strip 40. The unit is of the type shown in Fig. 3, in which a photo-sensitive sheet 12 is laminated to an image-receiving sheet 14, the sheets being bound together along their edges by the edges of a sheet 18 having a rectangular opening 28 through which the photographic exposure is made, and having at one end pods 16 containing processing liquid which are ruptured to spread the liquid between the sheets, and an element 20 at the other end for trapping unused liquid. Initially the sheets 12 and 14 are laminated together by introducing a laminating liquid between them from a nozzle 50 and then pressing them together between rollers 46, 48. The strip 40, which may be some hundreds of feet long, has the openings 28, and notches 42 and 44, stamped out initially. Strip 40 and the laminated sheets 12, 14 are brought together at a guide station 52, the laminate having been severed by a knife 58. The length of the laminate sheet now lies across the width of strip 40. Heat sealing jaws 64 (only one shown) seal the leading edge portion of the laminate to strip 40. A further pair of jaws 66 (only one shown) seals the laminate to strip 40 in the region surrounding the opening 28. At the next stage the pods 16 and the element 20 are sealed at opposite ends of the laminate, and at the next station the leading and trailing end sections 30, 32 are folded over. The unit is now severed by a knife 74, and the detached unit passed to further stations at which the marginal sections 34 are folded over and sealed. A number of inspection and monitoring stations are provided so that action may be taken immediately if any step is defective.

Abstract: 1,188,807. Traffic game. K. OHNBORN. 26 June, 1967 [29 June, 1966], No. 29294/67. Heading A6S. [Also in Division H4] A traffic game includes a plurality of remotely controlled carriages travelling on a surface each having its own driving source and control panel each of which includes means for controlling the speed and direction of the carriage. Alternating current generating means are provided in each panel F or each function to be performed, the frequency of each being different, the amplitudes being adjusted by the respective control means on the panels. A single electrically conducting loop is connected to the outputs of the panels so that it is supplied with all the A.C. From the panels and frequency sensitive receiving devices on each carriage each correspond to at least one function and are arranged to control the movement of the carriage. In an embodiment each control panel comprises two oscillators 13 and 14 (Fig. 2) which generate alternating currents of different frequencies from oscillator 13, the A.C. is supplied to a potentiometer 15, the slider 16 of which is actuated by accelerator pedal 17. Similarly, slider 23 of potentiometer 21 is actuated by turning the steering wheel 24 through different angles and different amplitudes of A.C. energy generated by oscillator 14 is supplied to the loop. When the steering wheel is turned to the right from the neutral position the amplitude of the current is increased and the signal received by magnetic receiving device 30 energizes a coil 36 which is associated with a movable magnetic core 37 which is coupled directly to the front wheels 44 and 46 which swing to the right. When the steering wheel is turned to the left less energy is supplied to the loop and the front wheels swing to the left. The forwards and backwards motion is controlled by hand lever 27 which when moved so that contact 26 engages contact 28 causes the whole energy from oscillator 14 to be temporarily supplied to the loop and energises coil 47. which surrounds a tube 48 of insulating material which contains a magnetized rod 50, so that the tube tilts over from one position to the other thus changing the direction of the vehicle. The speed of the vehicle is controlled by the accelerator pedal 17 which when pressed down to different degrees causes different amplitudes of A.C. energy generated by oscillator 13 to be supplied to the loop and received by magnetic device 31 thus energizing coil 65 associated with movable magnetic core 66. Core 66 is coupled to slider 59 of the potentiometer 58 the ends of which are connected across battery 57, the slider being connected in series with motor 60 across a part of the potentiometer. The current supplied to motor 60 depends on the position of slider 59 and on the voltage supplied to the loop from oscillator 13. A small diesel engine instead of a motor may be provided. The invention is suitable for motor car models and also for small boats driven in a water basin around which the loop is mounted.
