Abstract: 462,912. Magnetic separators. UNITED STATES STEEL CORPORATION. Sept. 17, 1935, No. 25816. Convention date, Sept. 22, 1934. [Class 72] In a method of separating materials, a suspension of the latter in a container is flowed under hydrostatic pressure through a transverse magnetic field, preferably produced by the rotating ends of magnetic poles, the magnetically attracted particles being moved progressively along the opposite sides of the container into channels of flow separate from the channel of flow of the main part of the suspension. The flow of the suspension may be divided into two streams flowing adjacent the wall of the container. In the apparatus shown, a fluid suspension of the material to be treated is fed by a shoot 26<1> into a container 16, provided with a water intake 26 and an overflow outlet 25 to give the desired hydrostatic head of fluid therein. The suspension is directed by baffles 27 towards a partition 8 which divides the suspension into two streams each of which passes into two passages formed between the lower parts of the partition 8 and the inwardy curved parts 7 of the container 16. In these passages the suspension is acted upon by a transverse magnetic field produced by rotating polepieces 13 which are energized by horizontal poles 1, 2, parts of which are enclosed by electromagnets 14. The magnetic material is attracted towards the parts 7, and the suspension carrying the same is directed into channels formed by internal partitions 4, 5 and passes away by pipes 17, 20. The suspension carrying the unattracted particles of the material passes between the partitions 4, 5, and is carried away by pipes 18, 19. To assist in the separation adjustably mounted pivoted gates 21, 22 are mounted so that their upper ends are close to the lower parts of the parts 7. The upper part of the container 16 may be divided into a series of channels by vertical fins, preferably mounted on the partition 8. The pipes 17, 18, 19, 20 may be provided with valves and also with washers having openings the size of which is so selected that the openings will not be clogged up.

Abstract: 632,167. Thermal switches. ZOUCKERMANN, A. Aug. 30, 1946, No. 26217. Convention date, May 16, 1939. [Class 38(v)] [Also in Group XXXVIII] A thermal switch used in monogrammic signalling apparatus (see Group XXXVIII) may comprise a wire 5 mounted between terminals 4 and 6, a spring contact blade 2 being connected to one terminal 4 and cooperating with a fixed contact connected to a third terminal 8. The whole is enclosed in a sealed glass tube 94 with the terminals 4, 6, 8 mounted externally. When contact 102 corresponding to a particular lamp 10 is selectively brought into contact with a corresponding wire 103 selectively energized from a power supply 16, the wire 5 expands and allows contacts 1, 8 to close. Current is thus applied to the lamp 10 over power terminal 23, main switch 12 closed, annular terminal 6, wire 5, contacts 1, 8, .and spring 95. When the contact 102 releases, the lamp 10 remains alight. If a switch 20 is reversed and the contact 102 closed again the wire 5 is short-circuited, and contracts, opening contacts, 1, 8, and -extinguishing the lamp 10. In a modification (Figs, 12, 13, and 14, not shown), the thermal relay is not enclosed and the terminals 4, 6 and 8 are formed as a threepronged plug. The mounting for the wire 5 may be of a material having the same co-efficient of expansion as the wire, to avoid the effect of outside temperature variations.

Abstract: 921,436. Extrusion machines. LONZA ELECTRIC & CHEMICAL WORKS Ltd. July 29, 1960 [July 31, 1959], No. 26485/60. Class 87(2). A single-worm extruder has a worm 1 characterized in that a number of turns 2 to 5 at the end a which faces the extrusion nozzle run oppositely to the turns 6 of the remaining part of the worm and that the product of the enclosed volume per turn and the pitch of these reverse turns is smaller than the corresponding product for the turns in the adjacent melting zone b of the worm, this being an essential condition for the production of a resultant feed motion towards the nozzle. The back-pressure which develops in the region of the reverse turns 2 opposes the feed motion and serves to miss the material which performs a motion in the pockets between the turns 2 approximately following a double spiral (i.e. a helix the axis of which is itself a helix).

In an arrangement for allotting one of a group of secondary circuits for association with a primary circuit, e.g. a line finder with a line circuit or a common control circuit with a selector, each secondary circuit includes a preselecting relay CB which when energized connects a start relay ST to a common start wire 10 and which in conjunction with a relay CN in series therewith controls a chain circuit running cyclically through all the secondary circuits. The preselected circuit is seized by the operation of ST when wire 10 is earthed, and in one course off-normal springs N1, N2 are actuated and a switching relay K (not shown) energizes. Relays CN, CB now fall back in turn and momentarily earth the chain circuit to energize relays CB, CN of the next idle secondary circuit. A guard relay CH which is dependent on actuated off-normal springs N2 prevents the operation of CB, CN should a secondary circuit return to normal while earth is present on the chain circuit. If all the preselecting relays are unoperated, as may happen during a period of heavy demand, group relay GP energizes and connects the chain circuit to wire 10, so that a starting earth is effective as a preselecting signal.
