Abstract: 126,813. Bellonby, L. A. May 21, 1918. Concrete, hardening. - A concrete mixture is rapidly hardened while in its mould by treatment in an apparatus in which it is successively subjected to the action of dry steam, hot water, and heated air. The apparatus consists of a series of chambers, une of which is shown in Fig. 3. Shelves 13 support the moulds or trays containing the plastic material, a hole in each shelf being disposed alternately at opposite ends of the chamber so that fluid delivered through the perforated plate 10 traverses the series of moulds. The chamber is drained by the gutter 7, the pipes 20 serving for the removal and re-admission of water. The rib 8, running the length of the chamber, keeps a shallow layer of water in the chamber, the steam coil 9 being placed with about half its thickness above the water. The apparatus is used by first admitting steam to the half-immersed coil, whereby the surrounding water is vaporized and passes over the shelves, after partial drying by the part of the coil above the water. Hot water is next pumped into the chamber, is further heated by the steam coil, and circulates through the side passage 16. The water is then completely drained off and hot air delivered to the shelves by the continued operation of the coil.

Title: Improvements in or relating to irradiating devices
IPC: G21F5/02
Filed: 1957-03-14
Abstract: 808,795. Containers for radio-active materials. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 14, 1957 [March 17, 1956], No. 8460/57. Class 98 (1) A capsule of radio-active material is fixed in a channel through a block of radiation-absorbing material, and a radiationabsorbing liquid is contained in the channel and can flow past the capsule to fill the variable space between the capsule and a radiation-permeable wall movable along the channel. As shown in Fig. 1, the capsule 4 is held in a channel 3 in a body 1 of radiation-absorbing material, e.g. lead in a sheet-steel casing, by ribs 5 and a locating ring 6. A window 8 of radiationpermeable metal is slidable along the channel and has rubber sealing rings 9. The channel between the window 8 and a piston 11 is filled with mercury 10. When the piston moves down, the mercury flows past the capsule 4 and pushes the window 8 along the channel until it absorbs substantially all the emitted radiation. More mercury 14 behind the piston absorbs radiation which might otherwise be emitted when the piston approaches the capsule. The piston rod passes through a cover 15, perforated to permit passage of air. In a modification, Fig. 2, the piston 11 has a tubular extension carrying the window 8, and the capsule 4, which has guide ribs 5, is supported by a thin rod 17 passing through the piston and secured to the cover 15. A spring 18 normally moves the piston outwards from the position shown so that the mercury 10 flows past the capsule and cuts off the radiation. The displacement of mercury by the rod 17 is allowed for by leaving an air space 21 between the piston and a disc 22 held against the mercury surface by a spring 23. The space above the piston is connected to a vacuum pump via a duct 19; when the pump is brought into action atmospheric pressure forces the piston inwards against action of spring 20 until the window 8 is in contact with the capsule, allowing passage of radiation. The capsule may be held by webs passing through slots in the tubular part of the piston, or it may be held in position by an annular magnet.

Filed: 1917-06-14
Abstract: 116,368. Wildey, E. M. June 14, 1917. Addition to 113,458. Screwing; turning.-In a chaser-holding device as described in Specification 113,576, means are employed to stop the feed-motion of the chasers, and withdraw them from the work, when a feeler comes into contact with a flanged portion of the work. The base carrying the pivoted arms e on which the chasers a are mounted is formed in two parts c<1>, c<2>, slidably connected but normally locked together by a bolt s<2>. When the adjustable eccentric collar r<1> of the feeler contacts with the work, the bolt q is pushed back relatively to the arm k in the base of which it is mounted, until a notched part q<3> engages with a recessed portion s<5> of the vertical bolt s<2> and allows the spring s<1> to lift the bolt s<2>, thus allowing the main portion of the device to remain stationary while the part c<1> may continue to move with the lathe saddle. At the same time, the portion s<5> of the bolt acts on the end t<1> of a pawl t', pivoted at t<2>, and lifts it from a toothed arc on the hub of the lever i, thus allowing the chasers a to be retracted through the medium of the spring i<1>, shaft l, and eccentrics n, n'. A projection u on the base c<2>, engaging with a slot v in the base portion c', may act as a position-stop for resetting the apparatus, which is done by sliding the part c<2> by a hand-lever w until the lever t<1> can be depressed, thus forcing the bolt s<2> into the base c<1> and releasing the bolt q which is returned to its normal position by a spring q<1>.

Patent GB-735791-A (GB)
Title: Treatment of nickel and cobalt solutions
IPC: C01G51/12
Filed: 1953-03-30
Abstract: Nickel ammonium sulphate and cobalt ammonium sulphate and ammonium sulphate are prepared from an acid sulphate solution of nickel and cobalt by reducing the acidity of the solution to a pH between 3 and 7 with ammonia, arranging to have at least one mol. of ammonium sulphate per each mol. of nickel and cobalt sulphate, concentrating the solution by evaporation to completely p  precipitate the nickel as mixed crystals of nickel ammonium sulphate and cobalt ammonium sulphate and discontinuing the evaporation at a point where the precipitated crystals contain from 1.2 to 3 mols. of ammonium sulphate for each mol. of nickel and cobalt sulphate, separating the precipitated crystals from the mother liquor and then evaporating the major part, but not all of the water from the mother liquor, thereby forming ammonium sulphate crystals which are separated, after which the final mother liquor is recycled to the first evaporation step. Such mother liquor still contains dissolved cobalt.  Both evaporation steps are preferably conducted at 20 DEG  to 60 DEG  C. and the second evaporation step is preferably stopped when the cobalt content of the ammonium sulphate crystals is not more than 0.1 per cent and the cobalt concentration in the mother liquor is between 2.5 and 4 grams per litre.  The mixed crystals of nickel ammonium sulphate and cobalt ammonium sulphate are preferably redissolved in water and the solution saturated with ammonia to form complex amine salts of the metal, which solution on heating to 230 DEG  C. under pressure in the presence of an oxidizing gas forms a precipitate of crystalline cobaltic amine salt free from nickel.  The cobalt salt is separated and the nickel solution further processed in known manner.  The sulphate solutions to which the invention is applied are preferably freed from lead, copper and iron before treatment, the iron being removed from the lead-free solution preferably as in Specification 695,517 and the copper removed next.  The original feed solution may contain about 6 per cent free sulphuric acid.  According to a typical example a solution of cobalt and nickel is treated with anhydrous ammonia until the pH is brought to 4 and the solution evaporated at 60 DEG  C. until the crystals separated shows a molar ratio of ammonium sulphate to nickel and cobalt sulphate of 2.14 to 1.  The separated crystals contained 99.96 per cent of the nickel and 97.1 per cent of the cobalt.  The mother liquor was then evaporated at 50 DEG  C. to crystallize ammonium sulphate containing 0.05 per cent cobalt and bring the cobalt concentration in the solution to 3.5 g.p.l.  The ammonium sulphate crystals were separated and the mother liquor recycled to the first evaporator.
