Abstract: 1,145,292. Rotary conveyer for sorting washing. SHORT BROS. & HARLAND Ltd. 22 July, 1966 [23 July, 1965], No. 31569/65. Heading B8A. [Also in Division B2] Articles of washing which are disposed at 50 and are required to be sorted out and delivered at 22, are separately placed on slide 51 by the operator stationed at 50 who presses a button which drops the article into the next transfer tray 26 or 27 contained in two superposed circular rotating tiers and at the same time codes the said tray. As the loaded tray passes the selected bin 11 or 12 of the two superposed stationary tiers shown the code operates to discharge the article into the said bin. When all the bins of both tiers have been filled the.operator goes to the discharge position 22 and presses a button to cause the circular tiers of bins 11, 12 to rotate past him to enable him to withdraw the contents of each bin for subsequent wrapping and despatch. Transfer trays 26, 27 (Fig. 2).-These are arranged in two superposed circular tiers carried by rotary frame 23 supported by wheels at 31 and 41 and driven by motor 33. Each tray corresponds to a bin 11 or 12, the bins being arranged on a circular frame 15 carried on wheels 16 and drivable by motor 18. Each pair of trays 26, 27 has a corresponding code 36 or 37 which is engaged by a trip 63 (not shown) to open trap doors on the tray to release the article down into the selected bin. When the selected bin is in the lower tier of bins the pressing of the button at the feeding station 50 causes the upper of the two approaching trays to be opened so that the article may pass therethrough and lodge in the lower tray after subsequent discharge in the selected lower bin.

Patent GB-410175-A (GB)
Title: Improvements in or relating to the treatment of oils
IPC: C10G21/18
Filed: 1932-11-11
Abstract: Mineral or lubricating oils are purified by extraction with a chlorinated ether, whereby naphthenic and other undesired components are removed.  The extraction may be preceded by a light sulphuric acid treatment, and may be followed by a light sulphuric acid treatment and (or) by treatment with clay.  The oil may be dewaxed before or after the extraction.  Specified chlorinated ethers are 2 : 2<1>-dichlorodiethyl ether, 2 : 2<1>-dichloro-di-n-propyl ether, 2 : 2<1>-dichlorodiisopropyl ether, trichloroethyl ethers, methylchloropropyl ethers, 1-chloroethylmethyl ether, 2-chloroethylmethyl ether, <PICT:0410175/III/1> 2-chloroethyl-3-chloropropyl ether, and chloromethyl-2-chloroisopropyl ether.  The chlorinated ethers may be used alone or mixed with other solvents; specified other solvents are liquefied propane, propylene, and butane, and also naphtha.  In the apparatus shown, the chlorinated ether layer obtained in the extractor 11 is passed to a still 20 from which the ether is distilled into a storage tank 27.  The purified oil is passed from the extractor 11 to a tower 32 in which it is freed from dissolved ether by treatment with a stripping agent, e.g. steam, carbon dioxide, nitrogen, propane or butane, the ether being condensed and returned to the tank 27.  Addition of ammonia or like base to the stripping agent is recommended.  In performing the extraction, the oil and the ether are mixed by the stirrer 12 in the extractor 11, and the mixture is preferably heated by the coil 13, e.g. to 100--170 DEG  F.  The mixture is then cooled, e.g. to 35--85 DEG  F., and allowed to separate into layers, which are worked up as described above.  The extraction may be repeated, and in that event the later extracts may be used to treat a fresh batch of oil.  The apparatus may be modified by withdrawing the purified oil from the top of the extractor, the solvent being then distilled directly from the extractor.  The Specification as open to inspection under Sect. 91 refers generally to the use of chlorinated solvents, and specifically to the use of chlorinated ketones, such as dichloroacetone, 2-chloroethylmethyl ketone, and chloropropyl ketones; chlorinated esters such as 2-chloroethyl acetate, methyl, ethyl, and propyl chloroacetates, chlorohydrins, and chloroformates; and ethylene dichloride.  Also, it claims processes in which a mineral oil containing paraffinic and naphthenic hydrocarbons is (1) extracted with any organic solvent and then treated with sulphuric acid or (2) treated with sulphuric acid, extracted with any organic solvent, and then treated with clay.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to photo-sensitive electronic cells
Inventor: FYNN GEOFFREY WILFRED
IPC: H01L31/08
Filed: 1962-08-21
Abstract: A slab of semiconductor material for use as an element of a photosensitive cell is provided with thickened regions by masking such regions of a blank slab with an insulating mask which is thicker than the amount by which the thickened regions are to protrude above the active surface of the finished slab, and the unmasked region of the blank is electrolytically etched until the desired thickness is obtained.  As shown, blank In-Sb slabs 3 each 5 x 1.5 mms x 100 m are placed over a Pt strip anode 4 in a polymethylmethacrylate jig 1 including removable masking cheeks 5 of the same material having edges 7 chamfered down to 2 mms and located by nylon screws 6 to overlie the slab margins by 0.5 mm. The loaded assembly is placed in a continuously stirred nitric acid-ethylene glycol bath and electrolytically etched for 3 minutes with a P.D. of 10 volts to reduce the slab thickness to 40 m , the etched surface being brushed at intervals to remove Sb2O3.  After removal from the jig, each slab is washed in ethanol and dipped into an HF-HNO3-acetic acid etching solution or lightly lapped with a fine wet abrasive. If the slab is of low resistance material, point contacts 10,11 are formed by soldering on with In-Sb solder Pt wires which have been etched in HNO3. For high resistance material (16 ohm.cm.), Pt strip contacts extending along the whole of the slab margins are provided.  These may be formed by flattening a portion of a Pt wire or may be of Pt strip corrugated by passage under a knurled roller. The contacts are cathodically cleaned with an applied P.D. of 12 volts in an alkaline sodium carbonate/phosphat bath and are then flash plated in an acid Cu bath using a Pt anode.  The coppered contacts are then "tinned", defluxed in CCl4, and rinsed in ethanol.  The electrolytically etched slab is then cleaned by dipping in heated solution used for the electrolytic etching and is then flash coppered in an acid bath, rinsed, heated, fluxed and the tinned Pt contacts soldered on to it by simple contact.  The completed device is then defluxed in CCl4, dipped in HNO3 to remove copper from the untinned areas, and then given a finish dip etch in the electrolytic etching solution to reduce the slab thickness by a further 20 to 25 m . The finished device may be given a coating of PbCl2 by vapour deposition to increase its sensitivity. <PICT:1029673/C6-C7/1>
