Title: Improvements in or relating to the production of metals
Inventor: BEST PETER
IPC: G21C3/64
Filed: 1956-07-09
Abstract: A powder mixture of uranium dioxide with an oxide of chromium, molybdenum, nickel, iron or niobium is compacted and heated in an inert atmosphere or under reduced pressure to reduce the metal oxide to metal at the boundary with the dioxide.

Title: Desiccated reforming
IPC: C10G35/085
Filed: 1961-06-13
Abstract: In the catalytic reforming of a petroleum naphtha in the presence of hydrogen and a platinum group metal catalyst, the water in the reactor is controlled to maintain the partial pressure of water at the outlet of the reactor not in excess a value of or corresponding to 0.4 mm. Hg. at 200 p.s.i.g. total pressure. The water is controlled by drying the feed to below 15 p.p.m. of water, preferably below 10 p.p.m., and the recycle gas to below 5 p.p.m. The catalyst is also preferably dried before use to a moisture content (compared with catalyst ignited for 48 hours at 1250 DEG  C.) of not more than 1.1%.  This is effected by passing a dehydrating gas through the catalyst and gradually increasing the temperature to not more than 1000 DEG  F. and not more than 20 DEG  F. below the deactivating temperature until at 950 DEG  F. and a gas rate of 24-240 Sc.F. per minute per barrel of catalyst the partial pressure of water in gas leaving the catalyst is not more than 1-3 mm. Hg.  During this treatment the surface area of the catalyst should not be reduced by more than 50%. Specification 891,863 is referred to.

Title: Improvements in and relating to processes of preparing pigmented coating products and pigment dispersions in resins and other binders and/or solutions of these
IPC: C09B67/20
Filed: 1957-01-08
Abstract: Dispersions of pigments in liquid vehicles are prepared by mixing pigment, a binder and a volatile solvent in a container by the application of shear forces at a rate of shear not less than 2000 secs-1 and diluting the dispersion with additional binder by evaporating at least some of the solvent from the dispersion whilst the latter is in a state of shear and simultaneously adding binder or vehicle to dilute the dispersion, such evaporation and dilution being continued until the dispersion contains sufficient binder to prevent re-agglomeration or re-aggregation of the pigment on further thinning and not more solvent than is required in the completed dispersion.  A partial vacuum may be created in the mixing vessel before dispersion is commenced.  A suitable apparatus is a twin contra-revolving sigma-bladed horizontal water-cooled and steam-jacketed paste or plastic mixer.  Rates of shear from 2000 to above 100,000 secs-1 may be employed.  Examples are given of dispersing Milori blue in a solution of alkyd resin in white spirit, and in a polymerized rosin dissolved in toluol.  Heat treated linseed oil may also be used as a vehicle.  The product may be used in paints, lacquers, printing inks and the like.ALSO:Dispersions of pigments in liquid vehicles are prepared by mixing pigment, a binder and a volatile solvent in a container by the application of shear forces at a rate of shear not less that 2000 secs-1 and diluting the dispersion with additional binder by evaporating at least some of the solvent from the dispersion whilst the latter is in a state of shear and simultaneously adding binder or vehicle to dilute the dispersion, such evaporation and dilution being continued until the dispersion contains sufficient binder to prevent reagglomeration or re-aggregation of the pigment on further thinning and not more solvent than is required in the completed dispersion.

Abstract: 1322115 Coating apparatus PONT-A-MOUSSON SA 19 April 1971 [20 Feb 1970] 22073/ 71 Heading B2L Apparatus for coating foundry moulds comprises a reservoir 1 pump 4, coating head 10 and a diaphragm pressure exchanger 5 which is connected on one side of a diaphragm 5a to the pump 4 and coating head 10 and on the other side to a control fluid supply pipe 19. With valves 6, 15 open coating liquid is pumped from vessel 1 into chamber 5b, the pressure produced by spring valves 16, 18 being insufficient to open an outlet valve in the coating head 10 but sufficient to push the control fluid from the chamber 4c since during this operation no air pressure from a pressurised supply is applied to the control fluid. Subsequently, with valves 6, 15 closed and the control fluid pressurised the coating medium is pushed from the pressure exchanger 5 and sufficient pressure is then available to allow the valve in the coating head to be opened. Excess coating medium returns to the reservoir via pipe 14. At this time the pump circulates coating medium, which may be a suspension of silica and bentonite, through pipes 17 and 14a. The mould may be rotated and axially reciprocated and the coating head may be reciprocated. In a modification the control fluid may be acted on directly by a pump. Several coating heads may be used simultaneously using one reservoir and pump and as many pressure exchanges as there are coating heads. The coating head 10 has a valve 12 normally closed by a spring 13. Coating medium enters through a pipe 9 and, depending on the pressure thereof exits either through ports 11 or 14.
