Title: Process and apparatus for contacting reactants with fluidized solid particles and the transfer of such particles
IPC: C10G9/32
Filed: 1954-12-22
Abstract: In contacting fluidized solid particles with reaction gases, the fluidized solid particles are circulated through a first vessel to a hopper and back to the first vessel, and some fluidized solids are passed periodically through a transfer line from the hopper to a second vessel and in the reverse direction by varying the pressure in the second vessel.  In this way, constant fluidized bed depth and time of contact are maintained in the first vessel.  The solids may be catalysts in a hydrocarbon cracking or hydrodesulphurization <PICT:0791155/III/1> process; alternatively the solids may be heat transfer media or may react with the gases.  In the apparatus shown, a residual hydrocarbon oil to be desulphurized enters at 30, together with hydrogen, and mixes with catalyst from pipe 26; after passage through two reaction zones 10a, 10b at 750-950 DEG  F. and a pressure of 250-2000 lbs. per sq. inch, the gaseous products separate from the catalyst in hopper 16 and leave through line 20, and the catalyst circulates through standpipe 24 and line 26.  Transfer of catalyst from the hopper 16 to regenerator 40 and back again is effected automatically by timer 48 which actuates differential pressure controller 47 and also actuates valves 60, 62 in transfer lines 58, 59; the pressure controller opens or closes valve 46 in the gas outlet from the regenerator 40 so that the pressure in this vessel is either above or below that in the hopper 16. Fluidizing gas is introduced at 64, 66 into the transfer lines. In a simplified form of apparatus, Fig. 2 (not shown), the first reaction zone comprises only one vessel, and there is only one transfer pipe between the hopper and the second zone. Specification 791,154 is referred to.

Title: Improvements in and relating to cathode ray tube apparatus and systems
IPC: H01J29/26
Filed: 1957-12-03
Abstract: 872,607. Cathode-ray tubes. PHILCO CORPORATION. Dec. 3, 1957 [Dec. 3, 1956], No. 37640/57. Class 39(1). A cathode-ray tube has a luminescent screen provided with portions emitting radiations of two different ranges of wavelengths and with a covering layer deposited on these portions for reflecting radiation of one range of wavelengths while transmitting radiation of the other range of wavelengths. In a colour television tube the green strips 44 are also indexing strips emitting ultra-violet or infra-red radiation. This radiation is transmitted through the layer 50 to a photocell 65 controlling the indexing system. A window 70 is provided in the wall of the tube for the emergence of the radiation. Anode layer 34 may be constituted to reflect the radiation as described in Specification 822,017. The glass face plate 60 of the tube may also be constructed to reflect the radiation. For emitting ultra-violet radiation the green strips, e.g. of magnesium activated zinc orthosilicate; may include unactivated zinc orthosilicate which also serves to balance the light output of the green strips relative to that of the blue and red strips as described in Specification 753,452. Alternatively there may be used activated zinc oxide which has two peaks of emission, one in the green region of the spectrum and the other near the ultra-violet region. Layer 50 may be of silver. For emitting infra-red radiation, the green strips may include manganese activated magnesium silicate. Layer 50 then consists of silicon, or germanium. Indexing material may be placed in the spaces between the colour phosphors instead of in one of the phosphor strips. The invention may also be applied to a monochrome tube in which indexing signals are used to stabilise the linearity of sweep.

Filed: 1960-11-16
Abstract: 904,115. Semi-conductor devices. FAIRCHILD SEMICONDUCTOR CORPORATION. Nov. 16, 1960, No. 39276/60. Class 37. A PNPN switching device has ohmic contacts at opposite ends at least one of these contacts short circuiting the first rectifying junction. Fig. 1 shows such a device consisting of end P regions 16, N region 12, a further P region 13 and end N regions 19. Ohmic connections 11, 22 extend over opposite ends of the device so as to short circuit the junction between P regions 16 and the surrounding N type material 12 and between N region 18 and the surrounding P type material 13. In operation the increase of the applied voltage from source 22 causes the current across the junction 12, 13 which is reverse-biased to increase slowly up to point B (Fig. 3 in curve X). At this point the junction begins to break down and the current increases to C. The current flow across the junction 12, 13 is then sufficiently large for junctions 17, 12 and 13, 18 to begin injecting when the voltage across the device falls rapidly. The device remains conducting to point D. As described, the device is of silicon and the ohmic regions may be electroplated or vapour deposited. In a further embodiment (Fig. 2, not shown), the short circuiting ohmic contact is provided on one face only of the device. A single region only is provided in the other face and the junction between this region and the junction between this region and the body of semi-conductor material is not short circuited. A further ohmic control contact is provided on this face. The operating curve of the device is shown at Y (Fig. 3).
