Title: Improvements relating to hopper feed apparatus
IPC: B65G47/14
Filed: 1947-01-03
Abstract: 620,081. Vibrating hoppers. BRITISH TIMKEN, Ltd., and McNICOLL, D. Jan. 3, 1947, No. 227. [Class 78 (i)] A hopper feed apparatus for roller bearings comprises (Fig. 1) a hopper 1 having a discharge opening 2, a separate outlet tube 5 movable within the discharge opening, and electromagnetic means 10 for vibrating the delivery tube. Fig. 1. A fixed frame 3 supports hopper 1 and electromagnet 10. The outlet tube 5 to which is attached flexible delivery tube 11 is carried by steel lever 6, which is held by springs 7, and is caused to vibrate about pivot 8 by core 9 of the magnet 10. Roller bearings introduced into hopper 1 are delivered by the vibrating delivery tube 11 to point 12 and their rate of delivery is decreased by friction spring 13 which passes through aperture 14 in tube 11, and so contacts each bearing as it passes. Fig. 2. The sliding non-vibrating delivery tube 15 slides through fixed frame members 16 and is supported therefrom by spring 18 so as to be separated by recess 17 from vibrating outlet tube 5. Bearings from the hopper are aligned by the vibrations of outlet tube 5 and pass through delivery tube and are delivered to shoot 20 by reciprocating slide 19. In the electric circuit of the vibrating magnet 10 are contacts 22, 23, of which 22 is carried by a lever which is fixed to and moves with the sliding tube 15, and 23 is fixed to frame 16; so that if there are so many bearings in tube 15 as to cause congestion, the tube together with said lever is depressed and contact 22 moves away from contact 23 and breaks the magnet circuit, stops the vibrating, and so causes the flow of bearings to cease. Fig. 3. For use with roller bearings that are tapered. Hopper 1 is fixed. Outlet tube 5 is carried by lever 6 vibrating about 8, and carries flexible delivery tube 11 which leads to stationary guide members 24, 26 in the lower one 24 of which there is a longitudinal slot 25. The tapered roller bearings which pass both tail-wise and head-wise through tubes 5 and 11, are pressed by the curve 27 of upper guide 26 into slot 25 all uniform tail downwards and are then delivered to tubes 28 and 33. Tube 28 is carried by arm 29 which pivots at 30. When tube 28 holds too many bearings and jams, its weight will cause arm 29 to pivot about 30 and, by depressing contact 34, to break the circuit of magnet 10 and stop its vibrations.

Patent GB-766198-A (GB)
Title: Coloured cellulose ethers and xanthates
IPC: D06P5/22
Filed: 1955-01-06
Abstract: Coloured cellulose ethers and xanthates are produced by dyeing cellulose to be used in their preparation by any known process, washing the dyed cellulose and treating it, after drying, if necessary, with sufficient aqueous caustic soda of sufficiently high concentration to convert the cellulose into alkali-cellulose, after which any excess of caustic soda is eliminated and the alkali-cellulose is comminuted and converted into a cellulose ether or xanthate.  The alkalicellulose may be ripened in the usual manner before being converted into a cellulose ether or xanthate. Etherification may be effected with ethylene oxide, propylene oxide or sodium mono-chloracetate, and xanthation with carbon bisulphide. The coloured hydroxy-ethyl or hydroxy-propyl cellulose may be used for dyeing viscose by adding a solution of the ether in dilute aqueous caustic soda solution to the viscose before spinning. Alternatively viscose may be prepared from coloured cellulose xanthate produced as described above.  The cellulose may be dyed by means of vat dyes of the anthraquinone or indigoid series, or by impregnation with naphthols and development with diazo compounds. The cellulose starting material may be cotton linters or a papermaking pulp.  In an example, cotton linters are dyed with 2.5 per cent of Solanthrene Blue powder SRN, washed, dried soaked in an aqueous solution of caustic soda (210 gm./l.) and pressed to remove excess solution.  The resulting coloured alkali-cellulose is ground, reacted for 7 hours in a rotating churn with propylene oxide (3 parts to 5 parts alkali cellulose as cellulose), and the product dissolved in 6 per cent aqueous caustic soda solution to form a blue solution, which is filtered.  In another example a paper-making pulp is dyed with 5 per cent brilliant green Solanthrene B, treated with concentrated aqueous caustic soda, pressed and comminuted, and the coloured alkali-cellulose is ripened at 20-21 DEG  C. for 48 hours. It is then reacted with carbon bisulphate (32 parts per 100 of cellulose) and the xanthate thus obtained is dissolved in dilute aqueous caustic soda solution to produce viscose, which, when spun in the usual manner, gives spun-dyed green filaments.

Title: Production of transfer images by the silver salt diffusion process and sensitive material therefor
IPC: G03C8/28
Filed: 1960-01-07
Abstract: 925,313. Photographic silver salt transfer processes and sensitive material therefor. AGFA A.G. Jan. 7, 1960 [Jan. 8, 1959], No. 627/60. Class 98 (2). A light-sensitive material comprises a support with a silver halide emulsion layer and an unsensitized colloid layer comprising a watersoluble starch ether, carboxymethyl cellulose or a water-soluble salt of carboxymethyl cellulose, the colloid layer having incorporated therein a polyethylene glycol, over the emulsion layer. Development nuclei may be included in the colloid layer and, preferably, a heterocyclic nitrogen-sulphur compound as well. After exposure the material may be treated in a transfer-developer and squeezed against a sheet as of writing paper to transfer all or part of the colloid layer containing a positive image thereto, and produce a laterally correct image on the sheet. Repeated transfers may be effected. Development may be effected with a solution which does not contain a silver halide solvent but such, and also the nuclei, may be incorporated into the transfer sheet. Two examples detail the process, the first using nuclei in the colloid layer and hypo in the developer and the second these materials in the transfer sheet. 5-phenyl mercaptotetrazole is used in the colloid layer in both instances. Specification 879,995 is referred to.
Patent GB-717673-A (GB)
Title: Improvements in or relating to hydrocarbon fuel compositions having improved anti-rusting properties
IPC: C10L1/24
Filed: 1951-01-10
Abstract: Oil-soluble lead sulphonates for use as fuel additives (see Group III) are prepared by reacting litharge with a sulphonic acid or by reacting a water-soluble lead salt such as lead nitrate with a sodium sulphonate.  The preferred sulphonates are derived from petroleum or synthetic alkylate sulphonic acids having a molecular weight between 350 and 500.  In an example benzene is alkylated with a propylene polymer in the presence of a hydrofluoric acid catalyst.  A fraction having an ASTM distillation initial point of 600 DEG  F. and a 10 per cent point of 660 DEG  F. is sulphonated with 25 per cent fuming sulphuric acid at a temperature between 80 DEG  and 100 DEG  F.  The sulphonic acid layer is neutralized with caustic soda and the crude sodium sulphonate slurry is dissolved in one part of a naphthenic light mineral oil and two parts of a petroleum thinner such as Stoddart solvent. Sodium sulphate is removed by washing with sodium chloride, and the sodium sulphonate is converted to lead sulphonate by reaction with lead nitrate at 150-160 DEG  F.  Inorganic salts are removed from the lead sulphonate solution by washing with hot water to which sufficient ethyl or isopropyl alcohol is added to prevent emulsion formation.  The solution is then filtered and the hydrocarbon solvent distilled off.ALSO:Less than 0.01 per cent. of a lead sulphonate is incorporated into a hydrocarbon base fuel boiling in the gasoline boiling range.  The gasoline may be a petroleum distillate, a cracked or straight-run stock or a blend of such stocks, an oil derived from shale or other bituminous material or a product of the Fischer-Tropsch synthesis.  Any oil-soluble lead sulphonate may be employed, but those derived from petroleum or synthetic alkylate sulphonic acids having a molecular weight between 350 and 500 are preferred.  The lead sulphonate may be prepared by direct action of litharge with the sulphonic acid or by reacting a water-soluble lead salt such as lead nitrate with the sodium sulphonate (see Group IV (b)).  If the fuel is to be carburetted a small amount of carrier oil may be introduced into it. such carrier oil being a hydrocarbon oil having a boiling range somewhat higher than that of gasoline and serving to keep the lead sulphonate in solution upon evaporation of the gasoline.  In example 3 there are reported the results of tests in which varying amounts of lead sulphonates derived from white oils are added to a commercial gasoline having a 400 DEG F. end point and an octane number of 83. Specification 595,814 is referred to.
