Patent GB-598173-A (GB)
Title: Improved process and apparatus for contacting powdered solids with gaseous fluids
IPC: B01J8/00
Filed: 1944-09-25
Abstract: <PICT:0598173/III/1> In the circulation of finely divided fluidised solid material through a closed system containing treating zones at different pressures, the material is withdrawn from the lower pressure zone through a star feeder into a pressure chamber to which a gas is admitted to raise the pressure sufficiently to enable the material to be transferred in suspension in a gas to the high pressure zone.  The invention avoids the use of standpipes and enables all parts of the system to be placed at ground level.  In the Figure, 10 is a converter, e.g., for cracking hydrocarbons, into which a suspension of catalyst in oil vapour is fed through distributor 18 so as to form a fluidised bed.  The reaction products are withdrawn through cyclone 26 which returns entrained catalyst. Exhausted catalyst is withdrawn through a slide valve 38, suspended in oxidising gas in pipe 42 and supplied to regenerator 12, which resembles the converter but operates at lower pressure.  Regenerated catalyst is withdrawn by star feeded 62 and passed into chamber 16 to which inert gas is admitted by pipes 64 creating pressure sufficient to return the catalyst into the current of oil vapour in pipe 14. Inert gas may also be passed into the star feeder by pipes 66, and an escape pipe 68 may be fitted to release the pressure in the rising compartments.  The exit gases from the regenerator may pass to a Cottrell precipitator 86 from which catalyst is returned to the regenerator through star feeder 92 and pressure chamber 94.

Title: Process for the production of deuterium enriched ammonia
IPC: C01B4/00
Filed: 1960-05-25
Abstract: <PICT:0952335/C1/1> <PICT:0952335/C1/2> In a process for enriching NH3 in deuterium by single temperature isotopic exchange in at least one reactor between liquid NH3 containing dissolved catalyst, e.g. amide of K, Cs, or Rb, and H2, at least one catalyst recycling loop is associated with at least one reactor in which the NH3 leaving the reactor is either partially evaporated and subjected to isotopic exchange with deuterium poor ammonia synthesis gas, or completely evaporated, and the resulting concentrated catalyst solution, or dry catalyst, is reinjected into the NH3 fed to the reactor. NH3 and NH3 synthesis gas are contacted in exchange towers 1, 2 which may be towers with plates or filling, or assemblies of such towers. Synthesis gas (H2+N2) is fed in at 5 (Figs. 3, 4) and synthesis gas is converted to NH3 in 4 whence D-poor NH3 is withdrawn at 7.  Liquid NH3 from 4 passes through 1, 2 to evaporator 8, whence evaporated NH3 passes to 3 for conversion to synthesis gas, which returns to reactors 2, 1 and D-enriched NH3 is withdrawn at 6.  In Fig. 3 concentrated catalyst solution from 8 is passed in isotope exchange with synthesis gas from reactor 1 in column 10, and returned to the NH3 feed at 9, while the synthesis gas is returned to reactor 1 at a point of similar D concentration.  In Fig. 4 the NH3 and catalyst from 2 is completely evaporated in 8 and dried catalyst returned to the NH3 at 9.  In alternative arrangements, Figs. 5, 6, 7 (not shown) two reactors are provided each of which has a separate recycle loop as described in Figs. 3 or 4, or one has a loop of the type of Fig. 3 and the other has that of Fig. 4.

[Also in Group XXII] In a flame-cutting machine of the kind in which a scanning head is controlled photoelectrically so as to automatically follow an outline, and in which the head normally leads the cutter, the lead is automatically reduced as the radius of curvature of the outline decreases. The scanning head is mounted on a carriage which is free to move in both X and Y directions and is moved by a motor driven wheel in contact with the tracing table. The wheel mounting is rotatable about a vertical axis so as to steer the scanning head. As it rotates about this axis it drives a tachometer generator to provide a signal proportional to the rate of deviation of the outline. This signal energizes a D.C. torque motor, Fig. 4 (not shown) to rotate it against a spring. As it rotates, it either rocks the pivoted lower portion of the scanning head into a more upright position, Fig. 2 (not shown), or moves the lower portion of the scanning head horizontally by a rack-andpinion, Fig. 8 (not shown); or rocks a block of glass within the lower portion of the scanning head so as to deflect the scanning beam optically, Fig. 11 (not shown). This block of glass is in all cases manually adjustable at right angles to the line of the tracing for kerf width copensation.
