Title: Flask filling apparatus
IPC: B22C15/20
Filed: 1937-09-20
Abstract: 495,226. Moulding-machines. BEARDSLEY & PIPER CO. Sept. 20, 1937, No. 25483. Convention date, Jan. 28. [Class 83 (i)] Relates to apparatus for filling flasks with sand by means of a projector with a selfcontained motor, which projector throws wads of sand into all parts of the flask and consists in a construction in which the projector is universally mounted. The apparatus is stated to have advantages over that disclosed in Specification 443,054. The sand in a hopper 82 is discharged at 86 with the aid of a rotating bottom 85 driven by gearing 91, 90 from an electric motor 88. A deflector 87 leads the sand to a shoot 83, from which it falls into a funnel 27 leading to a casing 12 for discharge in wads by a rotating tongue and centrifugal action, to a tube 34 under which is the flask. An electric motor 13 is integrally mounted with the projector and is supported by a yoke 42 attached to a rod 94 connected by a joint 99 with a plate 100, carried by a rotating disc 95. The disc is mounted on a shaft driven from an electric motor through belt gearing 102. The yoke 42 is pivotally mounted at its ends on members 43, which are also pivotally mounted on yokes 44. The latter are mounted with the aid of rubber convex faced blocks 49, Fig. 9, rubber snubbers 59 assembly bolt 60, brackets 47, 54 and adjusting means 58. A similar arrangement of convex faced rubber blocks and snubbers, obtains for the mounting of the yoke 42.

Abstract: 1,102,250. Gyratory electric motors. C. ROSAIN, and G. STCHERBATCHEFF. 9 June, 1966 [9 June, 1965], No. 25745/66. Heading H2A. In a gyratory motor producing a greatly reduced speed by means of a rolling action, both magnetic members are displaced in opposite directions by the rotating field generated in one of them, so that dynamic balance is achieved. In the form shown, one member has cores 2a, 2b excited by magnet 1 and riding on wheels 3a, 3b, while the other member generates a rotating field and has similar wheels 16a, 16b. These wheels act in tracks 13a, 13b mounted on a driving shaft 6. The magnetic elements are prevented from rotating by bolts 8a, 8b connected by universal joints to links 10a, 10b connected to the two members, again by universal joints. The members may be of different masses and move in tracks of different diameters to retain dynamic balance. In a modified form (Fig. 3, not shown) the field member rides in a single central wheel (105). The members are resiliently restrained by rubber pillars (28) connected to yokes (33, 34). The field windings are cooled by water tubes (38). In a modification of this arrangement (Fig. 8, not shown), a single core is used on both members.

Title: Improvements relating to methods of and apparatus for the production of zinc
IPC: C22B19/04
Filed: 1950-10-25
Abstract: Zinc is obtained from zinc-containing oxidic material and cokeable material by distillaton in vertical retorts, the cokeable material being first degasified and coked and then the zinc-containing material reduced and distilled, the zinc vapours and the coking gases being discharged through separate openings which can be opened and closed independently.  The coking may be carried out at 900-1000 DEG C and the reduction and vaporization of the zinc-containing material at 1100-1200 DEG C, the temperature being raised to the vaporizing temperature as rapidly as possible after coking is complete.  The furnace may be heated by the coking gases produced or by producer gas, or oxygen may be added to burn some of the coke.  Two or more furnaces may work together and be connected to a single condenser, the exhaust gas from the condenser being used as a heating gas.  The openings may be so arranged that closing the openings for coking gas opens the zinc vapour discharge openings.  Fuel and zinc-containing material may be charged as briquettes.
