Patent GB-767428-A (GB)
Title: Process for producing highly refined petroleum oils
IPC: C10G17/06
Filed: 1954-11-09
Abstract: White oil is produced by catalytically cracking a virgin petroleum distillate boiling at 600-1100 DEG F., separating cracked products boiling in about the same range, removing aromatics therefrom, and treating the product with sulphuric acid.  The catalytic cracking may be carried out at 800-1100 DEG F. and from atmospheric pressure to 25 p.s.i., using fluidized and non-fluidized catalysts such as montmorillonite clays, silica-alumina or silica-magnesia.  Aromatics may be removed by treating the cracked oil with selective solvents for aromatics such as sulphur dioxide, phenol, furfural and nitrobenzene or by treating with adsorbents.  The oil may be dewaxed, before or after removal of aromatics, for example by a solvent dewaxing process using solvents such as propane or methyl ethyl ketone. The oil may be treated twice with oleum and may be washed with aqueous sodium carbonate solution and then with an alcohol, e.g. a C2-C5 aliphatic alcohol such as isopropanol.  The oil may finally be clay treated, e.g. with attapulgus clay, bauxite or an activated synthetic clay.

Title: Improvements in and relating to methods of making photo-electric cells
IPC: C21B3/06
Filed: 1936-11-27
Abstract: 491,574. Photo-electric cells. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 27, 1936, No. 32540. Void. Convention date, Nov. 27, 1935. [Class 39 (i)] In the manufacture of a photo-electric cell, the envelope is sealed off from the pump after evacuation and then heated with the photoelectrically sensitive material, contained for example in a capillary extension of the envelope, to such a temperature that the vapour pressure in the cell is sufficient to produce a layer of photo-electrically sensitive material over the surface of the cathode. It is stated that, by this method, distillation can be effected at a relatively low temperature. Higher vapour pressure may be used so that at first a certain metal surplus is in the cell which can be removed by heating with the cell connected to the pump.

Abstract: 388,141. Beverages; gazogenes. WETSTEIN, J., 1225, Park Avenue, New York, U.S.A. Nov. 25, 1931, No. 32742. Convention date, Nov. 25, 1930. [Class 14 (i).] A liquid, such as fruit juice, in a renewable container 15 above a main body of liquid in an airtight vessel 5 is discharged preferably by means of compressed carbon dioxide in a capsule 17. The capsule acts as a stopper for an orifice in the bottom of the container, which is housed as shown inside a screw cap 14 with the capsule resting on a centre strap 8 of a ring 7. When the cap is screwed down on to a rubber ring 11 a washer 24 bears upon the container 15 forcing it down, so that a spike 19 is caused to puncture the end 22 of the capsule. Gas thereupon escapes into the container and forces the contents out into the vessel 5 where they mix with the liquid therein while the gas aerates the mixture. A vent 25 is provided for the escape of top pressure gas. In a modified construction the bottom of the capsule fits in a cup which is a driving fit in the aperture in the container, while the thrust on the container is produced by a screw plunger working in the top of the cap, which is secured by clips. The latter comprise a lever 43, Fig. 8, pivoted at 44 to the vessel 5 and a yoke 41 pivoted at 42 to the lever. The yoke engages a button 40 on the cap 14 and has an enlarged gap at 47 by means of which it can be detached from the button.

[Class 40 (v)] A modulated carrier receiver includes two carrier frequency channels of different selectivity and means, operable in dependence on the incoming signal strength, are provided to cause the selectivity of the receiver as a whole to increase as the signal strength decreases and vice versa. Fig. 2 shows parallel intermediate frequency amplifiers 3, 31 and 6, 11, the former being sharply tuned and the latter broadly tuned by the use of couplings less than critical and more than critical. The output from the highly selective amplifier 3, 31 is taken from the primary of the output transformer so as to be in phase with the output of the other amplifier, the input of which is taken from the primary of the input transformer M<1>. The gain of the two amplifier channels is differentially controlled by the rectifiers AVC, 2AVC which apply bias to one or more valves in each channel. Fig. 4 shows a modification employing a push-pull amplifier in which with strong signals the valves 51, 60 are rendered inoperative so that the remaining valves constitute a band - pass coupled amplifier. Weak signals are amplified by all the valves which are coupled by selective single tuned circuits. Alternative methods of feeding the two parallel amplifiers and combining their outputs in appropriate phase are described, Figs. 1 and 3, (not shown).

Abstract: 604,814. Current measurements. LEGGETT, P. W. N., and MAWBY, L. J. Dec. 10, 1945, Nos. 33360/45 and 33723/46. [Class 37] Apparatus for measuring the 'amplitude of very high frequency waves in wave-guides is arranged to have a high sensitivity which is maintained substantially constant over a wide range of frequencies. A detector wave-guide comprises a rectangular metal tube 1 of similar section to a coupling wave-guide 4 which may be inserted in a system under test. The ends of the tube 1 are closed by metal plates 2 at a distance apart equal to the average wavelength of the transmitted wave in the wave-guide 4. The tube 1 is supported on a block 3 with a guiding tongue 5 on its base so that it engages slidably in a slot 6 in the wave-guide 4. A stirrup 7 attached to the block embraces the coupling wave-guide 4 and supports a spring- loaded friction pad 8 bearing against-the underside of the coupling wave-guide 4. A vertical bore in the block 3 receives a bushing 10 of low loss insulating material such as polystyrene resin. On the upper wall of the tube 1 is mounted a tube 11 coaxial with the bushing 10 and fitted with a screwed plunger 12 carrying a coupling probe 13. This comprises a thin brass rod extending across the tube 1 through the bushing 10, and projecting into the coupling wave-guide 4. The axes of the guides 1, 4 are spaced with their axes one wavelength apart. On one side of the probe 13 at one-quarter of a wavelength from one end plate 2 and a half wavelength from the probe 13 is a crystal rectifier 14 with its axis parallel to the probe 13. A metal spigot 15 on the bottom of the rectifier 14 is connected to the bottom wall of the wave-guide 1 and is thus at zero potential. The other end of the rectifier 14 is provided. with a metal end cap 19 with which the insulated lead 20 of a screened cable 21 makes contact. The metal braided covering 29 of the cable 21 is held between bushes 27, 30 by a screw coupling 28, 31 and is insulated from the wave-guide 1 by a polystyrene resin insulator 23. The inner and outer conductors of the cable 21 are connected to a microammeter (not shown). An iris, for concentrating the wave at the centre of the wave-guide at the crystal comprises a pair of coplanar plates 32 which extend from the side walls of the waveguide 1 towards the centre, slightly nearer to the probe 13 than the axis of the rectifier 14. Waves emanating from the probe 13 and reflected from the closed ends 2 are substantially in phase at the probe with the field due to the probe, also waves emanating from the probe 13 incident on the rectifier 14 and waves reflected from both closed ends 2 are approximately or wholly in phase. In a modification, the end plates 2 are at a distance apart equal to one and a half-wavelengths and the probe 13 is centrally situated between them. Two crystal rectifiers are provided, one on each side of the probe and at a quarter of a wavelength from the end plates, each crystal having an associated iris.

The loads 3 each have a shackle 9 for suspension from hooks 7 of the conveyers 1, la. The transfer conveyer 2 has trolleys 18 running on rails 19 and is driven by pushers 16 of a traction chain 15 supported from rails 13. The pushers 16 co-act with dogs 17 pivotally mounted on the trolleys 18. The latter carries an outwardly extending fork 20, which at the beginning of the transfer, slides into engagement with the sides of a hook 1 of the conveyer 1. If the hook is pivotally displaced from the vertical (dot-dash lines Fig. 3), the sides 20 of the fork engage angularly projecting portions of the hook, and restore vertical alignment. The carriage 18 also includes a shackle lifting member 21 which is supported on a variable-height cam rail 23 by a follower roller 22. Suitable inclination of the rail 23 thus causes lifting of the shackle out of engagement with the hook 7. A downward inclination of the rail 23 results in a similar transfer action to attach the shackle 9 and its load 3 to the conveyer la. At the positions of transfer, a plate 24 (Fig. 6) carried by the rails 19, pulls down the dogs 17 out of engagement with the pushers 16.
