Patent GB-696992-A (GB)
Title: Improvements in means and method for producing a continuous sheet of integrated mica
IPC: D21H13/44
Filed: 1951-11-30
Abstract: 696,992. Mica. HEYMAN, M. D. Nov. 30, 1951 [Dec. 15, 1950]. No. 28165/51. Class 70, A continuous sheet of integrated mica is produced by reducing pieces of mica to flakes of less than four microns thick while immersed in an evaporative liquid medium, directing a continuous flow of liquid and flakes into a static chamber in which the flakes settle downward through the liquid and are deposited on the upper side of an upwardly sloping and upwardly moving web, thereafter extracting residual moisture from the deposit of flakes to form an integrated sheet, and finally removing said sheet from the web. The liquid media may be water, methyl alcohol, carbon tetrachloride, toluene or xylene. Mica is fed from a container 55 via a shoot 54 fitted with a vibrating device 56 into a funnel 52 which feeds to disintegrators 40, 42 and 43. Liquid such as water which may have been treated in purifier 10 is passed at uniform intervals of time, in uniform amounts and at a required pressure through proportioning pump 26, booster pump 27 and then into the disintegrators in which the mica is split to a thickness of about four microns. Longer particles are intercepted by dam 58 while passing down shoot 41 and these are again split in disintegrator 60. The flakes then pass to a classifier 64 which is reciprocated at 200 times per minute. Larger flakes pass to a further disintegrator 72 before being restored to the main flow, which is then discharged from shoot 70 and onto conveyer means 81 at a point at the bottom of a sloping tank 77. The flakes settle on the outer nylon web 83 and are subjected to vacuum treatment at 95 and at 92 to remove much of the water. The mica now in sheet form 98 is dried on a heated pulley 91 and in oven 100 and is then wound on drum 101. Specification 615,489 is referred to.

Title: Improvements relating to metal sinks
IPC: E03C1/182
Filed: 1945-10-25
Abstract: 603,613. Making aluminium alloy &c. sinks. BIRMETALS, Ltd., and GOODWIN, H. Oct. 25, 1945, No. 28244. [Class 83 (ii)] [Also in Group I] In a metal sink 2 of the type combined with a table-like metal surface 1 such as a draining board in which the table-like surface is a rolled metal plate cut to the required length and having a portion removed to leave an opening of the size and shape required for the mouth of the sink well or bowl, the latter is separately formed (e.g. cast, deep drawn or welded) and jointed to the underside of the plate. The removal of the portion of the plate is effected by a stamping-out operation, or by such operation followed by a pressing operation, to produce a slight downwardly curved edge or lip 3 which is then machined or ground down flush with the under-surface of the plate to provide a flat mating surface for the upper edge of the sink well or bowl. Both sink and plate are preferably of aluminium alloy, the plate being formed integrally with a back-splash flange 4 and provided along its front and ends with beads' or roll edges 5, 7 terminating in depending flanges 6, 8. The sink well or bowl is secured to the underside of the plate by screws or bolts 15 passing through holes in projecting lugs or a flange 14 on said well or bowl, into blind holes formed in the plate from its underside, and the joint suitably sealed ; or the screws or bolts may be replaced by a suitable plastic adhesive, e.g. " Redux." The beaded flanges 8 serve to locate the plate 1 on wallbrackets 9, whilst the sink bowl is preferably cast integrally with waste and overflow openings 11, 12 and has a separately cast overflow 13. In an alternative form (Figs. 3, 4, not shown), beading to plate 1 is afforded by separate mouldings secured to the plate by screws.

Patent GB-803766-A (GB)
Title: Manufacture of hydrogen
IPC: C01B3/16
Filed: 1956-09-17
Abstract: <PICT:0803766/III/1> Hydrogen free from nitrogen, oxides of carbon, and oxygen is obtained by treating a bed of a heavy metal oxide with fumes resulting from catalyst regeneration in a catalyst exacting plant at elevated temperature in a reducing zone, and removing the reduced metal oxide to another zone where it is treated in a fluidized bed with steam at elevated temperature to form hydrogen and the metal oxide.  In a preferred embodiment, an iron ore such as haematite is contained in the reducing zone 1 and air and refinery tail gas are admitted through 3, to reduce the ore, which then passes through 9 into zone 13, into which steam is admitted via 15, which reacts to reform the original ore and high purity hydrogen.  The hydrogen is removed via cyclone 17.  The reoxidized ore is returned to the reducing zone 1 via 5.  It is desirable in general that zone 1 is placed higher than zone 13. In this way zone 1 can be operated at only slightly above atmospheric pressure whereas the hydrogen from 13 is generated at pressures equivalent to one stage of compression. The process is carried out between 1200 DEG  and 2000 DEG  F., preferably between 1500 DEG  and 1800 DEG  F.  It is advantageous to maintain the catalyst regenerator gas in an anhydrous condition, and to remove any carbon dioxide present by washing with an alkaline solution. Specifications 578,323, 586,914, 628,417 and 639,554 are referred to.
