Filed: 1916-07-05
Abstract: 107,644. Burrows, L. F. July 5, 1916. Extracting. - Iron ore, mixed with reagents necessary to remove undesirable constituents, is treated with a gaseous reagent obtained from steam so as to reduce the ore without melting it, the product being afterwards melted, with an addition of flux to separate the iron from the gangue. An apparatus for use in the treatment of the ore comprises an expansion chamber A with dome 41, steam-inlet pipe 40, and valved outlet pipe 45 for water of condensation, a rotary chamber E, in which the ore is treated, and a number of precipitation chambers C, in which various byproducts volatilized from the ore are deposited. The chamber E is enclosed by a heating chamber B, provided with a burner 16 and supplied with air through an opening 18, the waste gases escaping through an opening 19. Iron ore to be treated is placed in the chamber E which is continuously rotated and heated by the burner 16. Steam at about 60 lb. per sq. in. is discharged from the pipe 40 and expands in the chamber A which 's surrounded by atmospheric air. A certain portion of the oxygen of the steam is said to pass through the metal walls of the chamber and the remainder, it is said, passes into the chamber E. The steam may be produced in any suitable way; after the process has been started, the steam may be generated in a coil H, supplied with water from a pipe 51. The gaseous product, said to be obtained in the chamber A, is conducted by a pipe 53 to coils I in the chamber F, and thence by a pipe 54 to a nozzle 55, which projects through a trunnion 10.

Title: Improvements in electric relays
IPC: H01H47/16
Filed: 1936-04-01
Abstract: 474,668. Electromagnets. RYDER, C., BRAITHWAITE, R. C., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 1, 1936, No. 9684. [Class 35] [Also in Group XXXVII] In an electromagnetic relay, preferably of the quick-acting impedance type, each or either of the armatures is formed with a portion of ordinary magnetic material which is shrouded on the face nearer the co-operating electromagnet by a portion of high permeability metal or alloy such as Mumetal (Registered Trade Mark). As shown in the Figure applied to an impedance relay with a voltage electromagnet 6 and current electromagnet 5, the armature of the former comprises a plate 4 of ordinary magnetic material to which is secured on the face adjacent to the fixed core a plate 8 of Mumetal or other high permeability material, insulating material 9 being, if desired, interposed between the plates. The fixed core 6 may also, if desired, be made to include a portion of such high permeability material. By this construction it is stated that the calibration of the impedance relay can be maintained over a wide range and under varying conditions and the effects of hysteresis minimized. When connected in a line circuit operating with variable power-factor the voltage winding or the voltage and current windings may be fed through a rectifier or a system of rectifiers, thus rendering the relation between the forces exerted by the magnets on their armatures substantially independent of power-factor and also preventing chattering of the armatures.
