Title: Improvements in or relating to the regeneration of molecular sieves in separating hydrocarbons
IPC: C10G25/03
Filed: 1958-02-25
Abstract: In the separation of normal paraffins from hydrocarbon mixtures by adsorption at 200-400 DEG  C. on a molecular sieve wherein the adsorbed hydrocarbons are desorbed by a desorbing agent at the same temperature as the adsorption is performed, the desorbing agent itself being adsorbed on the sieve and in turn desorbed by the normal paraffins in a subsequent adsorption step, the sieve is periodically regenerated by heating to 650-850 DEG  F. under conditions effecting a reduction in the partial pressure of the p  adsorbed material.  The feed to be separated is preferably first dried and purified by passage through a 4  or 5  molecular sieve, preferably at a lower temperature than the separation step, or silica gel.  Separation is then carried out using a 5  molecular sieve at 0.25-2 wt./wt./hr. and 0.5 atmosphere-100 p.s.i.g.  The desorbing agent may be an olefine such as propylene or butylene, butanol or ethylene oxide.  Reduction of the partial pressure of adsorbed material is effected by reducing the pressure, preferably below 100 mm. Hg, or by using a purge gas, such as nitrogen or methane, or a combination of these two methods. In either case the sieve may be heated by passing a heated inert gas through the sieve.  Regeneration in the manner is preferably effected every 100-300 cycles.

Abstract: 1,034,021. Projector mountings. CONTINA BUREAUX-UND RECHENMASCHINENFABRIK A.G. Feb. 11, 1965 [Feb.11, 1964], No. 6071/65. Headings G2E and G2J. A cine or slide projector contains a support foot 4 which is extended from or retracted into the projector by motor-driven means to adjust the tilt or elevation of the projector. The reversible motor to preferably one included in the projector for other uses, and drives, through high reduction gearing, a screw spindle 3 whose engagement with the threaded bore of foot 4 thereby causes the above extension or retraction from housing 1. Spring-loaded pin 10 enters longitudinal slot 42 to limit the movement of foot 4. This movement is initiated when pedestal mount 2 is tilted about pin 5 by means of levers 6, 7 and displaceable manual control knob 22 as in Fig. 3 (not shown) to engage pinion 12 on spindle 3 with a worm 14 whose shaft 16 is driven through further gearing as in Fig. 1 (not shown). Lever 7 is adjustable to set the mesh between pinion 12 and worm 14. When fully retracted, spindle 3 may continue to run, but pin 10 rides over cam slot 41 to leave slot 42 and foot 4 may then rotate. When fully retracted spindle 3 unscrews completely from foot 4, and re-engages when the drive is reversed. In a modification as in Figs 6-10 (not shown) foot 46 has a longitudinal slot 47 which merges into the surface of the foot at top and bottom where camming surfaces 48, 49 for pin 10 are provided. The tilting of pedestal 2 is here controlled by a rotatable knob 56 through shaft 55 and link 53 attached to the pedestal by pin 61.
