Title: A process for improving soaps from oxidation products of nonaromatic hydrocarbons ofhigh molecular weight and apparatus therefor
IPC: C07C51/42
Filed: 1936-11-12
Abstract: Saponified oxidation products of non-aromatic hydrocarbons of high m.w. are freed from unsaponifiable constituents by introducing such saponaceous mixture containing at least 25 per cent of water into a tubular vaporizing plant at 100 atmos. or higher pressure and releasing the pressure to atmospheric within the tube system, the temperature in the tubes being such, e.g. 310-350 DEG  C. as to maintain the soap liquid.  The pressure may be reduced in stages, and a vacuum pump may be arranged beyond the condenser for the steam and unsaponifiables to ensure the pressure falls to atmospheric in the tube system.  Before saponification, the oxidation products may be <PICT:0487317/III/1> freed from readily soluble and strongly acid products by water, acids, dilute alkali, or organic solvents.  The saponification may be effected in presence of water, alcohols, ketones, or hydrocarbon solvents, and by the saponification equivalent or more or less of alkali.  Before treatment in the vaporizer the saponified mixture is preferably (1) freed from any unsaponifiables separating as an upper layer; (2) maintained above 220 DEG  C., e.g. at 250-330 DEG  C. for some time to convert lactones, hydroxy-acids, and the like into ordinary fatty acids and improve the colour and odour; this preheat treatment may be in presence of hydrogenating agents, e.g. hydrogen or zinc dust.  The saponaceous mixture may be sprayed or atomized into the vaporizer along with steam or other inert gas or vapour, or be forced in under the pressure generated by heating the mixture in a closed vessel. The apparatus shown may be used for continuous working.  Determined proportions of caustic soda solution from a tank 2 and of oxidation product from a tank 1 flow through a mixer 3 and, without the upper layer of unsaponifiables withdrawn by a pipe 5, through a filter 6, and are forced by a pump 7 through a valve 8 and a tube 9 in which the mixture remains for 2 hrs. at 320 DEG  C. and 160 atmos.; the pressure is released to 25 atmos. by a valve 10 and to atmospheric by a valve 11.  The mixture passes to a vessel 14 from which the soap passes to a cooling roller 15 to form flakes, while the steam, unsaponifiables, and coloured and malodorous vapours pass to a condenser 16 and a separator 17; the unsaponifiables are returned to the oxidation apparatus by a pipe 19, and water is removed by a pipe 18.  The soap may be dissolved in water and treated with dilute sulphuric acid to separate fatty acids which are further refined by distillation at 2 mm. pressure with steam.  In another apparatus the crude saponified mixture is pumped through a preliminary pipe system in which it remains for 1/2 hr. at 330 DEG  C. and 130 atmos., and is then atomized into the vaporizing tubes along with steam at 190 DEG C.; the mixture is heated therein to 350-400 DEG  C. and passed to a separator for the soap, the vapours passing on to a condenser.

Abstract: 410,107. Clutch-operating mechanism for vehicles. AUBIN, E., Elmstead, West Wittering, near Chichester, CLAREMONT, A. W., Vernon House, Sicilian Avenue, Bloomsbury Square, London, (Representatives of ROYCE, SIR F. H.), and DAY, B. I., Wittering House, Duffield Road, Allestree, Derby. Nov. 7, 1932, No. 31314. [Class 80 (iii).] In a clutch-operating mechanism for vehicles, undesirable movement of the clutch pedal relative to the chassis, caused by movement of the engine in, for example, its rubber mountings, is obviated by supporting the fulcrum shaft by a system of floating levers which compensate for any such movements. The fulcrum shaft d is supported at one end by a ball and socket joint d<1> and at the other end by a pendulum lever c which allows the shaft to swing fore and aft. The lever c is anchored by a lever e to the clutch housing and the clutch pedal is connected to the clutch lever g by the link g<2>. The levers are so proportioned that any movement of the pedal caused by movement of the engine relative to the chassis is compensated for by movement of the pedal fulcrum shaft through the lever e.

Abstract: 446,683. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, TAYLOR, R., 30, Oulton Road, Wavertree, Liverpool, and BAKER, G. T., Blackbrook, Cµrphilly, Glamorganshire. Nov. 3, 1934, No. 31652. [Class 40 (iv)] In a group selector in which an idle line is indicated by battery on the test terminal, the test relay is connected through a rectifier to the test wiper and on operating, connects up the switching relay which extends the test wire to the test wiper for the control of metering and holds subsequently to earth or booster battery fed back thereover. The invention is applied to a double-hunting bi-directional selector which continues its rotary movement upon release and then drops and rotates back to normal, as described in Specification 391,123. One of the test relays serves also as the dialling relay. Upon seizure, line and release relays A, B energize and impulses are repeated to vertical magnet VM in series with the left-hand winding of HX which holds between impulses due to the short-circuiting of its right-hand winding. A selfinterrupting circuit is made for rotary magnet RM on the relapse of HX, and HX, HY are connected through rectifiers MRA, MRB to test wipers P1, P2. When an idle line is found, one or other of these relays energizes to battery on the test terminal, short-circuits its high-resistance left-hand winding, cuts the drive and connects up the appropriate switching relay HA or HB, which extends the test wire and is held subsequently by earth or booster battery fed back from the succeeding selector. Relays A, B and HX or HY fall back. If both relays HX, HY energize, only HA operates, since the circuit of HB is opened by HX. If no idle line is found, HY energizes in the eleventh position, and cam springs S operate to send back busy tone and flash. Upon release rotary magnet RM operates to advance the wipers clear of the banks, after which they drop and return to normal.
