Title: Improvements in or relating to means for automatically controlling the flow of air
IPC: F23L1/00
Filed: 1936-03-03
Abstract: 469,258. Automatic control systems. JOHNSON, G. W. (American Engineering Co.) March 3, 1936, No. 6441. [Class 38 (iv)] [Also in Group XII] Fluid pressure.-Consists in means for automatically controlling the air supply in a stoker and comprises a pressure chamber and a duct extending therefrom with a restricted throat opening, and a control damper in the duct adjusted by reversible power means controlled in dependence on the differential pressure across the throat, follow-up means being provided to render the power means ineffective when the proper adjustment has been effected. The Specification describes a control arrangement for the air supply to a multiple retort having stokers 1, Fig. 1, of the underfeed type, the air supply being through separate ducts 13, 14, 15 which communicate with a chamber 12 supplied with air from a blower. Each duct has two controls, a throat damper 17 forming a Venturi opening, and a control damper 18. The throat dampers on all the ducts are linked together and operated simultaneously by a reversible motor 19, Fig. 2, controlled in dependence on the pressure in the chamber 12 so as to maintain the pressure in this chamber constant. This is effected by a reversing switch comprising a bracket 42 carrying two pairs of contacts 50, 51 and attached to a linkwork 60, 64 moved by the motor 19, and co-operating with a contact member 53 moved in response to the air pressure by a float 47 moved by the liquid 43 in a U-tube formed by the two cylinders 41, 42. If the pressure is too high the motor is energized to open the dampers 17, the follow up device causing the circuit to be broken after a given movement has taken place. The control dampers 18 are moved individually in response to the difference in pressure between the chamber 12 and that at the throat of the duct by means of reversible motors 65. If, for example, the fire fed by a particular duct becomes thin, the throat pressure in the duct will drop and the damper 18 will be moved to restrict the amount of air passing to the fire. This motor is controlled by a reversing switch 95, 96, 97, Fig. 4, operated by a beam 87, on which act differentially two pistons 85, one being subject to the pressure of the chamber 12, and the other. being connected by a pipe 92 to the throat of the duct formed by the damper 17, so as to be responsive to the throat pressure. The beam is loaded at 93 to compensate for the normal pressure difference. The contacts 96, 97 are attached to a linkwork connected to the motor 65 to give a follow-up movement. To give additional compensation when the deviation is large the beam has at its centre a tank 108 containing a liquid, preferably mercury, which when the beam is inclined moves to one side and prolongs the period of dwell of the contacts. By this means a larger correction is obtained which will enable the abnormal condition of the fire to rectify itself. Specification 412,033, [Group XII], is referred to.

Title: Process for the recovery of zinc
Inventor: STEWART LESLIE
IPC: C22B19/04
Filed: 1966-02-15
Abstract: 1,186,852. Producing zinc. L. STEWART. May 10, 1967 [Feb.15, 1966], No.6562/66. Heading C7D. Zinc is recovered from materials consisting largely of impure Zn and ZnO by melting them and allowing the molten material to percolate through an externally heated carbonaceous mass, thus distilling off the metallic Zn and reducing the oxidic material with subsequent distillation of the Zn so formed. The carbonaceous mass (e.g. anthracite or high temperature vertical retort gas coke) is preferably hotter at the bottom than at the top and may be heated by means of gas burners. Further carbonaceous material may be added separately or with the oxidic charge to obtain a relatively constant surface level in the charge. The surface however is preferably sequentially reciprocated across the column to prevent coagulation, arching or sticking of the carbonaceous mass. The Zn vapour may be extracted by a jet type suction pump, preferably powered by the molten Zn, the vapour withdrawn at the top of the column is produced by the direct distillation and that at the bottom is produced by the reduction of the ZnO followed by distillation and the Zn produced is preferably maintained in a molten state in the condensers.
