Title: Improvements in and relating to the production of alcohols
Inventor: REED HUGH WILMA OULTON
Filed: 1953-04-22
Abstract: Aliphatic alcohols containing from 6 to 22 carbon atoms in the molecule are produced from starting materials containing at least one free fatty acid containing from 6 to 22 carbon atoms by a process comprising thermally esterifying the acid or acids with an alcohol containing from 6 to 22 carbon atoms in the molecule or a mixture of such alcohols, used in a proportion of at least 5 per cent in excess of the stoichiometric at a temperature above 150 DEG  C. and at such a temperature and pressure that the alcohol is below its boiling point and the water formed is expelled as steam, and thereafter subjecting the product to hydrogenation in the liquid phase at elevated temperature and pressure in the presence of a foraminate copper catalyst in continuous manner.  Suitable fatty acids are those obtained from natural oils and fats.  In addition to the acids, glycerides and/or higher alcohols may be present in the mixture.  The preferred foraminate catalyst is foraminate copper/aluminium formed from an alloy of copper and aluminium in the proportions by weight of from 40:60 to 80:20.  In the examples palm oil is esterified with C8-C18 alcohols and the crude ester is hydrogenated according to the process of the invention to give C8-C18 alcohols.

Title: Improved expansion valve for refrigeration systems
IPC: F25B41/06
Filed: 1953-04-23
Abstract: 728,628. Refrigerating. GENERAL MOTORS CORPORATION. April 23, 1953 [May 9, 1952], No. 11161./53. Class 29. [Also in Group XXIX] An expansion valve for refrigeration systems comprises a valve closure member 16 adjustably loaded by a spring 34 by which it is urged towards a seat 18 upon increase of pressure in the evaporator 123 communicated by a passage 47 to a spring-loaded diaphragm 48 which is connected by a pin 40 to the valve member, and a diaphragm 133 whose upper face is subject to the pressure of a volatile fluid so as to be responsive to the temperature at the outlet of the evaporator 'and which has a lost-motion connection 149, 151 with the diaphragm 48. The arrangement is such that the valve member is normally controlled solely by the pressure responsive diaphragm 48 but in the event of excessively low temperature at the outlet of the evaporator due to the presence of liquid refrigerant, the diaphragm 133 rises under the effect of a spring 153 and takes up the lost motion to increase the throttling afforded by the valve. An adjustable spring 155 acts on the upper side of the diaphragm 133, and the space between the diaphragms may be either evacuated or connected to a resilient bellows 137 outside the chamber so that the pressure in the latter varies with atmospheric pressure.

Abstract: 705,931. Photographic developing apparatus. KEHR, W., LESJAK, M., and STRAUSS. R. May 11, 1951 [May 11, 1950] No. 11225/51. Class 98(2) In a daylight developing tank for photographic roll films of the kind having guide members for the film, a container for liquid and a spool mounted in the container and rotatable from the exterior, the spool consisting of a core and two end discs with internal opposite spiral grooves, a lead strap being provided of which one end is attachable to the core of the spool and the other end is attachable to the leading end of the film, and the introduction of the film into the tank being effected by attaching the lead strap to the core and to the film and rotating the spool whereby the film is led into the grooves, beginning with the inside grooves and proceeding outward, being bowed by the guide members to enable it to pass between the end discs of the spool, the distance between the spool discs and the distance between the guide members can be varied. As shown, the tank has a developing chamber 1 and a chamber 2 in which a film spool or cassette is placed, chambers 1 and 2 having a single-light-tight cover 4. The film spool has a pair of spirally grooved discs, one disc 8 being fixed to the spool axle 10 and one disc 9 being slidable thereon, but prevented from rotating on the axle by engagement with a longitudinal groove 11b. The spool is rotatable as a whole by means of a milled knob 6. A member 12 is movable axially with disc 9, but isprevented from rotation by arms engaging the sides of the chamber T, and carries a guide member 13 The film 15 passes between guide member 13 and a corresponding guide member 14 fixed to the cover 4, which bow the film and guide it between the discs 8, 9. The end of film 15 is clipped to the end of a band attached to the axle 10, so that when the spool is rotated by means of knob 6 the film 15 is gradually drawn into the grooves. When the disc 9 is moved along the axle to accommodate films of different widths, member 12 also moves to vary the distance between the guide members 13, 14. In modifications, member 12 is omitted, and guide member 13 is mounted on the cover. It may be slidable and capable of being locked in any desired position, or it may be screwed into one of a number of screw-threaded sockets in the cover. Alternatively interchangeable covers may be provided with guide members in different positions.
