Title: Hydrogenation of Unsaturated Aliphatic Compounds in Acid and Ester Solvents
Inventor: HOF LEENDERT PIETER VAN T
IPC: B01J27/06
Filed: 1967-04-03
Abstract: 1,179,504. Hydrogenation; isomerization. UNILEVER Ltd. 3 April, 1967 [7 April, 1966 (3)], No. 15157/67. Headings C5C and C5E. Unsaturated aliphatic compounds are hydrogenated by hydrogen in a liquid-phase process in the presence of a catalyst comprising a solution of a stannous halide and a chloroplatinous or chloroplatinic acid compound (e.g. free acid or salt thereof) in a C 2-10  aliphatic carboxylic acid or an ester thereof, e.g. ethyl acetate or glycerol triacetate. The starting compound may be an olefin, an acetylene, or an unsaturated fatty acid glyceride, specific compounds mentioned being ethylene, propylene, hexene-1, octene-1, octadecene-1, ethyne, propyne, and fatty oils from sunflower, safflower, cottonseed, fish, whale, soyabean and rapeseed. By suitable choice of conditions the catalyst can be made selective, e.g. soyabean oil having 3 ethylenic bonds can be selectively hydrogenated to a product having only one ethylenic bond. The catalyst also favours isomerization, e.g. with hexene-1 starting material some of the product is hexene-2 and hexene-3, and with glyceride starting material any double bonds not hydrogenated are geometrically isomerized to the trans-form.

Abstract: 679,722. Radiolocation; saw-tooth generating circuits. DECCA RECORD CO., Ltd., and McDERMOTT, T. J. June 8, 1950 [June 8, 1949], No. 15299/49. Classes 40 (vi) and 40 (vii). A cathode-ray tube deflection circuit for producing a plan-position-indicator display comprises a cathode-ray tube having two fixed deflecting coils for each component of deflection energized by separate respective sawtooth generator circuits of the magnetic-Miller type. Control voltages as shown in Fig. 1 are applied from a sine-cosine voltage generator 10, which is preferably of the type described in Specification 679,723, to four separate saw-tooth current generators energizing respective deflect. ing coils. Fig. 2 shows one saw-tooth generator comprising a magnetic-Miller time-base circuit wherein the feed-back is effected by a cathodefollower 21, thus providing a circuit of infinite output impedance for energizing the deflecting coil 22. The control voltage Vc is applied through the resistor Rg to the control grid of valve 20 and the sweep is initiated by the application of a gate pulse to the normallyconducting diode 26 to render it non-conducting. The sweep-rate may be controlled by a suitable choice of the condenser 25, the length of the gate-pulse being adjusted accordingly. To prevent screen-grid current from affecting the current flowing through resistor Rk, the screengrid of valve 21 is coupled to its cathode through condenser 23. In a modification, Fig. 3 (not shown) a resistor is placed in parallel with the coil 22 to over-critically damp the tuned circuit formed by stray capacities associated with the deflector coil and a further linearizing resistor is arranged in series with the condenser 25.

A machine for shaping a wing surface 19 or the like, capable of being generated by straight lines as claimed in the parent Specification, comprises at least three contour plates 27, 28, 30, 31, one of which (27) corresponds to the desired cross-section of the wing surface, whilst two others (30, 31) have cam surfaces 32, 33 which face in the opposite direction to the contour track and engage followers on the carriage 23 at the end of the beam 12, so that the tilt of the carriage is controlled and so that a third follower is positively held against the contour track. The end milling cutter 10 on a carriage 11 is rotated by a motor 13 through a flexible drive 14 and gearing 15. The beam 12 slides in a mounting 17 carried on a ball joint 18, which is cut away to allow the cutter 10 to approach closely to its centre, which represents the point from which the generating lines emanate. The beam is attached to the carriage 23 by a pivot 22 lying in a plane containing the axis of the tool, and mounted in a bearing pivoted on a horizontal axis. There are two cam plates 27, 28 having parallel edges corresponding to the crosssection of the wing surface, and contacted by two rollers 47 on a common pivot of the carriage 23. Above the plates 27, 28 are the two cam plates 30, 31 having non-parallel edges 32, 33 which control the tilt of the carriage, and are contacted by rollers 52, 53, respectively, in advance of, and behind, the rollers 47. Other rollers 56-59, 62, 63 engage the inner edges of the cam plates to hold all the follower rollers positively in contact with the cam surfaces. The carriage 23 is fed in small increments by a screw 51, between traversing cuts by the tool 10. If the generating lines of a surface meet at a point so distant as to render it inconvenient to have a pivot point thereat, two carriages 23 'may be provided with their lead screws connected by gearing to give the required proportionate movements. For making a mirror image of a workpiece, the pivot point 18, in the first embodiment, may be placed on the opposite side of the carriage 23, or the cam plates supporting the two carriages of the second embodiment may be interchanged.
