Title: Improvements in or relating to rotary furnaces
IPC: F27B7/00
Filed: 1933-07-18
Abstract: 422,793. Rotary furnaces. McGREGOR, A. G., Selection Trust Building, Mason's Avenue, Coleman Street, London. July 18, 1933, No. 20323. [Class 51 (ii)] Charging and discharging.-In a rotary furnace, adapted particularly for the treatment of cassiterite by a chloridizing process, the charge material, after being preheated in the upper part 16 of the furnace, is fed to a series of tubular muffles 22 arranged in ring formation about an axial heating chamber into which a burner 34 delivers, there being provided in connection with the muffles supply and discharge valves adapted for automatic operation during rotation of the furnace. The charge passes from the preheater 16 through apertures controlled by valves 53 to an annular header 25 divided by radial partitions into compartments corresponding to the number of muffles and communicating therewith through apertures fitted with valves 50. The valves 50, 53 are alternately operated, when in their uppermost and lowermost positions respectively, by the engagement of rollers 52, 54 on their stems with fixed cams 52<a>, 54<a>. The muffles 22 discharge into an annular header 26 fitted with a pair of valves 35, 36 which are alternately operated to deliver the material to a discharge shoot 44 by cams 42, 43. Reagents necessary for the process being carried out, e.g. a mixture of carbonaceous material and salt, are delivered to each of the muffles from a small supply hopper 57 through a shoot 70, the supply being controlled by a valve 55 operated by the engagement of a roller 58 with a fixed cam track 58<a>. The stem of the valve 55 carries a plunger 62 which, when the valve is lowered, positively forces the material into the shoot 70. The hoppers 57 carry trip members 67 which, as the furnace rotates, engage trap doors on a fixed shoot 69 and ensure that each hopper is replenished just before the valve 55 opens. The gases evolved in the muffles, e.g. stannous chloride when treating cassiterite, pass into a fixed annular chamber 29 fitted with water sprays 31 and having an outlet pipe 32 for carrying away any uncondensed gases and the solution produced by the water sprays. Specifications 403,122 and 412,273, [both in Group III], are referred to.

Abstract: 356,858. Cupping. FITZPATRICK, H. D., 94, Hope Street, Glasgow.-(Marquette Tool & Manufacturing Co. ; 1900, North Kilbourn Avenue, Chicago, U.S.A.) July 8, 1930, No. 20626. [Class 83 (iv).] In a double-action cupping press the plate 55 is gripped and cupped over a die 46 by the mechanical descent of a die 14 co-operating with a draw ring 54 yieldingly supported by air pressure in a telescoping cylinder 47 supplied from a tank 59 through a hand-controlled valve 61, piping 57, and conduit 58, the die 46 being prevented from descending by the piston 22 supported by liquid trapped in the cylinder 19. The work is then partly shaped as in Fig. 2, after which the die 18 descends on the work and co-operates with die 46 which is now allowed to descend by the release of the trapped liquid in the cylinder 19 through the spring-pressed valve 26 when the liquid pressure exceeds the spring pressure, and later the valve 26 is fully opened by a timed lever system 46a, the liquid escaping back to the pressure liquid tank 35 through a flap valve 37. The work is then completed as in Fig. 3. The release pressure on valve 26 is set by hand-wheel 28 abutting against the spring. When the dies 18, 14 ascend again the draw ring 54 also rises under the air pressure in the cylinder 47 to strip the work. During this movement the valve 39 is opened by mechanically-operated rod 41 so that pressure liquid can flow from the tank 35 through the valve 39 to the underside of the piston 22 through a one-way valve 31 (the flap valve 37 also being a one-way valve only). The cylinder 47 can telescope over the top of the cylinder 19. An exhaust valve 64 on being opened allows the draw ring 54 to be lowered.
