Title: Circuit arrangement with transfluxor
IPC: H03K17/82
Filed: 1959-05-29
Abstract: 891,405. Trarisfluxors. STANDARD TELEPHONES & CABLES Ltd. May 29, 1959 [June 3, 1958], No. 18360/59. Class 40 (9). [Also in Group XIX] The reset input to a transfluxor is produced by switching a core of the same square loop material so as to obviate temperature effects. As shown in the stepping-register of Fig. 4, alternate shift pulses on lines P1 and P2 alternately reset transfluxors K0, K2, &c. and the intervening cores K1, K3, &c. Should one of the transfluxors K0 be set, a shift pulse resets it to a blocked. condition and output from winding a2 sets the following core K1. The next shift pulse on P2 switches K1 which over the loop W2, S1- sets the transfluxor K2. Coupling between windings e and a enable the transfluxors to be interrogated. If interrogation always accompanies shift pulses on line P1, the arrangement of Fig. 5 may be employed. If transfluxor K0 is set an A.C. signal in winding e produces an A.C. output in winding a which is rectified to set the core K1. When K1 is reset by a shift pulse on line P2 output in the loop W2, S1 sets transfluxor K2 which is interrogated to set core K3 before the next shift pulse on line P1 to set the transfluxors. A single shift pulse line in common to the transfluxors and intermediate cores may be used if delay lines are placed in the coupling loops; see Figs. 6 and 7 (not shown). Diodes on the coupling loops prevent back-coupling but are not necessary in the loop between, say, core K1 and transfluxor K2 if the setting of K1 is done sufficiently slowly not to induce a switching voltage in the loop. It is pointed out that a transfluxor may be set as the result of a number of applied pulses.

Abstract: 579,061. Extrusion presses. DOWNS, L. H., and BELLWOOD, R. A. Nov. 8, 1943, No. 18489. [Class 46] [Also in Group III] Oil is extracted from fleshy material such as whale or other meat, fish or fish offal by subjecting the material to alternating pressure and to heat while being continuously conveyed along open troughs submerged in water or an aqueous extraction liquor such as brine. In Fig. 2, the material, which according to the Provisional Specification is preferably in cube or sliced form, is fed into hopper 4 and falls into one end of the open trough 5 which is submerged under hot water. A conveyer 7, which may be of the worm screw or worm paddle type, carries the material to the far end of the trough, while similar conveyers 21 and 22 subsequently carry it along troughs 6 and 15. It is then carried by elevator 17 to chute 19 and goes on to further treatment such as pressing. Certain sections of the worms of conveyers 7, 21 and 22 are arranged, by reversal of pitch, to give the material a negative acceleration and it is this that produces the alternating pressure effect. Steam or hot water may be sprayed on to the material passing along the troughs through jets 12 or through holes in the shafts of the conveyers. Oil extracted from the material floats to the surface of the water and passes through orifices 18 to a settling tank or oil separator.
