Abstract: 854,259. Discharging materials from vehicles. KNUTSEN, M. E. Feb. 21, 1957 [Feb. 21, 1956; March 16, 1956], Nos. 5338/56 and 8313/56. Class 78 (4). Agitators 19 near the junction of the end wall and main body of a vehicle body are disposed V- wise on opposite sides of the discharge outlet. The agitators 19 preferably comprise perforated plates backed by porous material through which air passes to fluidize material directed towards the outlet by tipping the body. The drawing, which is a view from the discharge end of the body, shows two discharge outlets 17 separated by a deflecting ridge 18 and leading to a delivery pipe 16 along which material is conveyed by a flow of air introduced through a conduit 22 which is also connected through branches 25, 26 to provide air for the agitators 19. Valves 28, 30 control the passage of air and material along the pipe 16. The portion of the body containing the discharge apparatus described may be hinged along the line X-X.

Patent GB-834154-A (GB)
Title: Improvements in the preparation of hydrogen peroxide
IPC: C01B15/023
Filed: 1958-02-21
Abstract: In the production of hydrogen peroxide by a process comprising inter alia partial or complete catalytic reduction of an organic compound, e.g. a 2-alkyl anthraquinone or an azo benzene, in a solvent medium with hydrogen optionally containing an inert gas, regeneration is effected by periodically passing inert gas free from hydrogen, or containing hydrogen at a partial pressure less than that of the hydrogen in the reduction stage into contact with all or a portion of the catalyst in the presence of all or a portion of the reduced solution.  The process comprises catalytic reduction with hydrogen of an organic compound in a solvent medium, oxidation with oxygen which may be pure or in the form of air of the reduced solution after removal of the catalyst, thereby regenerating the original organic compound and simultaneously producing hydrogen peroxide, and recycling of the oxidized solution to the reduction stage after extraction of the hydrogen peroxide with water.  Normal hydrogenation, catalyst regeneration and oxidation may be carried out at substantially atmospheric pressure.  The regeneration gas may comprise inert gas at a partial pressure of at least 0.1-0.3 atmos. and hydrogen at a partial pressure of not more than 0.7-0.9 atmos. Regeneration may be effected at a temperature of 50-150 DEG  F., for a period of 1/3 -4 hours.  Regeneration may take place in the hydrogenation vessel using a suspended or non-suspended catalyst. Solution and suspended catalyst may be withdrawn continuously or intermittently, and regeneration effected in a separate vessel. Inert gases specified are nitrogen, argon, helium, methane and ammonia. Quinones specified are 2-ethyl, 2-tert.-butyl, and 2-n-propyl anthraquinone, and 2-ethyl, and 2-tert.-butyl tetrahydroanthraquinone, and a mixture of 2-ethyl anthraquinone and 2-ethyl tetrahydroquinone.  Solvent media specified are benzene, xylene, dichlorobenzene, cyclohexanol, methyl naphthalene, a mixture of alkyl benzenes having a boiling range of 365-415 DEG  F., and a mixture comprising benzene, xylene, toluene, di- or tri-ethyl benzene, tetramethyl benzene, methyl naphthalene, diphenyl, or diphenyl oxide, and cyclohexanol, diisobutyl carbinol, monyl alcohol, hexanol, dibutyl phthalate, dibutyl sebacate, or di-isobutyl ketone. Catalysts specified are unsupported palladium and Raney nickel, and palladium supported on alumina, aluminium silicate, and bone char. Less than 50% of quinone may be converted to quinol.  As catalyst activity decreases further catalyst may first be added.  The catalyst may then be regenerated and a portion removed from the solution.  An example is given.

Abstract: 1,251,719. Removing CO 2  by sorption on activated carbon. F. BONOMI. 3 Feb., 1969 [2 Feb., 1968; 19 April, 1968], No. 5750/69. Heading B1L. [Also in Division F2] An activated carbon sorber 1, of particular use in removing CO 2  from the controlled atmosphere employed in preserving horticultural products, is connected on its input side through pump 5 to 2-way valve 6 and on its output side to 2-way valve 7. In the sorption phase (see A), controlled atmosphere containing CO 2  enters by line 8, passes through sorber 1 and is returned free from CO 2  by line 10. When the sorber is saturated, valve 6 is switched (see B) to allow an external atmosphere to enter by line 9 and flush the controlled atmosphere in the system. After a few seconds, valve 7 is switched (see C) so that the desorbed stream exhausts to waste through line 11. When the activated carbon is reactivated, valve 6 is switched (see D) to flush the desorbing stream in the system to waste through line 11 with controlled atmosphere which enters through line 8. After a few seconds the cycle is completed by switching again to mode A so that little or no controlled atmosphere is lost. The system is so constructed that the flow rate through line 9 is greater than through line 8, so that the regeneration phase is much more rapid than the sorption phase.

Projections 126 on the member 112 mate with the related plugs 90, to position them within the openings 92. In operation, the plugs are lowered, and /core mixture, e.g. silica sand and 2 per cent dry phenol binder poured around the plugs and baked by the heat of the cope. The plugs are then lifted, and a small amount of mixture may be poured into each cup and baked to increase the thickness of the bottom wall. The supporting member 112 is then retracted and the opening in the bottom of the cups cleaned out.
