Title: Magnetic switching device
IPC: H03K17/82
Filed: 1962-01-30
Abstract: 974,520. Magnetic storage devices. AMERICAN MACHINE & FOUNDRY CO. Jan. 30, 1962 [Jan. 30, 1961], No. 3478/62. Heading H1T. To counteract the effect of the flux produced by the bidirectional (primary) current in the input winding 18 (Fig. 1) of a transfluxor on the boundary of the area in which the flux is switched during unblocking, a means 20 is provided which creates a flux round the central aperture 13 in opposition to the flux produced by input winding 18. The input current is asymmetric with a small negative amplitude to ensure that it does not itself unblock the transfluxor. During unblocking the flux in leg 17 is switched (instead of the flux in leg 16) if the alternating input current in windings 18 and 20 at that instant produces fluxes in opposition to the (limited) unblocking current flux in leg 16. If the unblocking current is large enough to block the transfluxor in the reverse direction the next large input half wave through windings 18 and 20 switches the flux in leg 16, producing unblocking. In another embodiment (Fig. 4), separate blocking (35) and unblocking (34) windings are provided, primary input signals of the waveform shown being provided by oscillator 36 which is also connected to unblocking winding 34 through a resistor 40 (or a capacitor, Fig. 5, not shown) so as to produce, by currents in 34, fluxes round central aperture 27 which oppose the disturbing effect of the primary current in 32 on the unblocking operation.

Title: Improved method and apparatus for carrying out catalytic hydrocarbon conversion reactions
IPC: B01J8/32
Filed: 1943-03-04
Abstract: <PICT:0585990/III/1> In processes for the catalytic conversion of hydrocarbons, e.g., cracking, of the kind in which a suspension of hydrocarbons and catalyst is passed through a reaction chamber and the conversion products are separated from the contaminated catalyst which is regenerated by contact with combustion gases in a regenerator the regenerated particles being returned to the reaction chamber and supplying to the hydrocarbons the heat necessary for the conversion reaction, the velocity of the hydrocarbons passing through the reaction chamber is maintained at least twice that of the regenerating gases passed through the regenerator.  The regeneration gases leaving the regenerator are freed from residual catalyst by scrubbing with the hydrocarbons to be converted which are thus preheated.  A tubular reactor 12, the top of which projects into a separator 22, is employed in conjunction with a regenerator 10 of diameter at least twice that of the reactor.  The spent gases pass through a superposed cooler 28 and scrubber 32 through which the used gases pass and are vented to atmosphere via pipe 34.  The upper portion 27 acts as a separator and the catalyst is maintained in a dense suspension above a perforated plate 122 a baffle plate 127 forming a conduit 128 through which regenerated catalyst is fed into a stand pipe 16 communicating with the bottom of the reactor 12.  The general path of the oil is via pipe 42 to the scrubber 32 and thence through pipes 56, 18 to the bottom of the reactor, optional diversion through heat exchangers 62, 84 being available.  The conversion products are separated from the catalyst in the separator 22 and the general path of the catalyst is through a pipe 108 to an injector 115 where it is mixed with oxidizing gases supplied by a pump 118 and thence upwardly through the pipe 14 into the bottom of the regenerator 10 the regenerated catalyst being returned through conduit 16 to the reactor.  The conversion products are removed through line 24 to a fractionating tower 26 where fractions of different boiling ranges are segregated and led off through pipes to strippers 186, 194, 206.  The vapours passing into the bottom of the tower are washed to remove residual catalyst by recycling bottoms through line 152, 156, 174 and sprayer 178, heat exchangers 62, 158 providing means for cooling the cycle oil, e.g., by heat exchange with the feed stock in heat exchanger 62.
