IPC: C10G47/00
Filed: 1930-06-19
Abstract: <PICT:0349342/III/1> High grade lubricating oil is obtained from heavy unrefined petroleum oils containing small quantities of asphaltic, gummy or resinous impurities by heating the oil in presence of hydrogen to 700-850 DEG  F. under a pressure in excess of 25 atmospheres so that the production of oils boiling below 400 DEG F. is limited to below 20 per cent and preferably to 5-10 per cent of the oil treated. The production of oils of low boiling-point is controlled by varying the feed rate, in conjunction with the size of the reaction drum and the temperature to which it is heated and by the use of suitable catalysts.  Oil is fed from a pipe 24 and a manifold 26 through preheating coils in condensers 11, 12, 13 and pipes 28, 5 to a heating coil 1, and reaction drum 4, where it is mixed with hydrogen supplied through lines 8, 30.  The products pass to condensers 11, 12, 13, 20 and receivers 17, 18, 19 and part of the condensate from the condenser 11 may be returned to the drum 4 through a pipe 14<1>.  The oil may be recirculated through the reaction zone by a pipe 5, and the gaseous and liquid products of the reaction are separated in a separator 21. Specification 348,834 is referred to.

Title: Improvements in or relating to pneumatic force-balance signal transmitters
Inventor: HALLETT HENRY ALBERT
Filed: 1955-07-05
Abstract: 837,412. Fluid-pressure servomotor control systems. CHELTENHAM AUTO CONTROLS Ltd. June 18, 1956 [July 5, 1955], No. 19344/55. Class 135. A pneumatic signal transmitter comprises a relatively movable baffle and nozzle arrangement 17, 18. The nozzle 17 is mounted in a wall of a body 11 and has a bore leading from a chamber 32. Compressed air at constant pressure is fed via pipes 13, 15 and a restrictor 16 to the chamber 32 from which air may pass via restrictors 35, 36 to atmosphere. The bore of the nozzle 17 constitutes a tapping between restrictors 16, 35. The baffle 18 is movably carried by an extension 30 of a rod 25 one end of which is attached to a double balancing bellows 28, 29 and the other end of which is attached to an input bellows 20 which is connected to a detecting element e.g. a temperature-responsive bulb 19. The bellows 28, 29 is connected via a tapping 39 to the pipe 37 between the restrictors 35, 36 and the chamber 32 is connected via the pipe 40 to the remote instrument 42 e.g. an indicator or recorder or process controller, to which the signal is to be transmitted. Due to the restrictor 35 the feedback pressure transmitted to the bellows 28, 29 via the pipe 39 will be less than that at the nozzle 17 and as the restrictor 36 is adjusted to its closed position the feedback pressure builds up to the value of the pressure at the nozzle.
