Title: Purification of alcohols
IPC: C07C/
Filed: 1962-01-17
Abstract: Alcohols containing 2 to 30 carbon atoms, derived from the oxidation and hydrolysis of an aluminium alkyl growth product, as hereafter defined, are purified to remove colour and odour by hydrogenation, in the liquid phase, at 40-250 DEG C., 50 to 2000 p.s.i.g. over a stationary bed of supported nickel catalyst containing at least 40% nickel by weight, the alcohol feed being charged to the reaction zone batchwise or continuously. Alcohols of 6 to 18 carbon atoms may be purified by effecting the hydrogenation over a supported catalyst containing from 40 to 80% by weight of nickel at 115-140 DEG C., 50 to 175 p.s.i.g.  The alcohols are obtained by interacting an aluminium alkyl, e.g. aluminium triethyl, tripropyl, tributyl or tri-isobutyl, or diethyl aluminium hydride or ethyl aluminium dihydride with ethylene or a low molecular weight alpha olefin, e.g. propylene or butene to give a growth product containing C2 to C28 alkyl groups.  After oxidising to yield the alkoxides the reaction product is hydrolysed to give a mixture of alcohols, which may be subjected to the hydrogenation in toto or after separation into fractions, e.g. C6-10, C12, C16-20 and C20+ in examples.  Suitable hydrogenation conditions are 40 to 250 DEG C. at 50 to 2000 p.s.i.g. for 1-120 minutes using 0.1 to 1.0% by weight on the alcohol of catalyst; in batch operation 115 to 140 DEG C., 50 to 175 p.s.i.g. 60 to 75 mins., 0.1 to 0.2% catalyst are preferred conditions.  Data for continuous operation are provided.  The catalyst may be supported on alumina, silica, kieselguhr, pumice, kaolin, activated carbon or bauxite, which may be impregnated with a reducible nickel compound and reduced. The preparation of the crude starting alcohol is also described.

Filed: 1967-01-17
Abstract: 1,178,761. Machinery safety devices. PHILIPS GLOEILAMPENFABRIEKEN N.V. 17 Jan., 1967 [17 Jan., 1966], No. 1885/67. Heading F2J. [Also in Division E2] In a washing and centrifugal machine or dishwasher having a door giving access to a rotatable part which is adapted to be driven at two different speeds, an unlocking mechanism for the door comprises an electro-magnet and a centrifugal switch which opens the energizing circuit of the electro-magnet at the high speed of the rotatable part and closes it at the low speed of the part so that the door can only be opened when the magnet is energized. To start the machine, a push-button 9 is pressed to close a switch 10 and connect a driving motor winding 1 with mains terminals 11, 12. This is only possible if the door 8 is closed and locked, due to the presence of a micro-switch 13. The motor is coupled mechanically to a centrifugal switch 3 in the control circuit of an electromagnet, comprising a coil 4 and core 5, controlling an unlocking mechanism 14, 15, 16 for the door 8. A spring 22 holds the core 5 in the locking position when the electromagnet is not energized. In order to open the door 8, a push-button 7 is depressed so that push-button 9 returns to its initial position and the voltage supply to the motor is interrupted by switch 10 being opened. The centrifugal switch 3 is open whilst the machine is rotating at high speed, thereby preventing energizing of the coil 4 to unlock the door. At the lower speed of rotation, required for washing, the switch 3 is closed and the electromagnet energized thereby unlocking the door 8. Similarly the door may be opened when the machine is stationary. If the mains supply is cut-off, the mechanism may be unlocked by means of a screw-driver acting on a plate 19 coupled to core 5 by a cable 17 located in a housing 18.

Filed: 1953-01-24
Abstract: 783,161. Image dissector tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 25, 1954 [Jan. 24, 1953], No. 2109/53. Class 39(1). An image of a scene is projected on to photocathode 2 so as to release an electron image of the scene which is then scanned over a target electrode structure 4, the scanning motion and the construction of the target electrode structure (for example the provision of four spaced apertures 5) being such that the electron images is divided into separate juxtaposed areas which are simultaneously scanned, individual trains of electrical signals being derived which are representative of the separate areas. The time taken to scan the entire scene, which may be a target area, is thus reduced while the scanning speed is not increased and thus the signal/noise ratio is not reduced. As shown the target electrode 4 is backed by sets of multiplier electrodes 8 and screens 9 each set terminating in an output electrode 10 ; or the multiplier electrodes may be common to both streams so long as the streams are separate, and screens for this purpose may be provided. Another modification, Fig. 2 (not shown), uses a common output electrode and the signals from the various apertures are separated, in accordance with Specification 783,163, by modulating the stream leaving each aperture at a different high frequency by means of a grid; frequency discriminators in the ouput circuit will then separate the signals. In this form the first few multiplier stages may be individual to each stream, and a reducing electron lens may be inserted between these stages and later common stages of smaller size, Fig. 3 (not shown).
