Title: Improvements in or relating to the preparation of homogeneous concrete and like mixtures
IPC: B28C7/08
Filed: 1960-04-05
Abstract: 888,042. Concrete mixers. AUGUST, P. April 5, 1960, No. 18294/61. Divided out of 888,041. Class 86. A transportable semi-automatic concrete mixer shown in the working position comprises a framework in the form of a right-angled triangle and a stationary horizontal mixing drum 13 having mixing means carried on a rotatable axial shaft driven by a motor 10 through a clutch, gearing and chain drive, (see Figs. 4 and 8 not shown). The motor also drives winches for hoisting and loading skip 5 and for operating a scraper shovel 95 (see Fig. 1 not shown). In operation the loaded skip, which has rollers 71 engaging a runway 4, is hoisted by operation of its winch and at the top of its travel tilts to discharge its contents into the opening 25 of the drum 13. At the same time a stop member 66 (see Fig. 6 not shown) on the skip 5 strikes the lever 59 which cuts off the supply of water to the water drum 46 and opens a discharge cock to discharge its contents into the mixing drum 13. The water drum may be provided with an internal sloping outlet tube the inclination of which is adjustable from astride the drum, to regulate the amount of water discharged. When the skip 5 is returned to its bottom position the stop 66 strikes the lever 65, which closes the discharge cock of the water drum 46 and opens the filling cock. At the same time the operator withdraws manually the locking bolt 31. The drum 13 being freely supported in trunnions is rotated anti-clockwise under the influence of the rotating stirrer shaft, until it has turned through 180 degrees when the locking bolt 31 engages in the recess 29 and the drum discharges through the opening 25. The loading skip 5 in its upward travel is arranged to disengage automatically the locking bolt 31; the drum is then rotated clockwise under the influence of the spring buffer and recuperator mechanism 36, 40 from the discharging to the charging and mixing position. The mixing action is rapid and takes place during the time required to reload the skip 5. The mixer is transported by tilting it about the feet 97 until it rests on the road wheels 3, (see also Fig. 2 not shown). The skip 5 may be stored within the frame. The mixer may be re-erected by detaching the cable 74 from the loading skip, fastening it to a ground hold fast 100, Fig. 1 (not shown) and operating the skip winch.

Title: Process of and apparatus for the treatment of zinc ores and other zinciferous materials
IPC: C22B19/36
Filed: 1926-07-22
Abstract: 268,201. Job, W. July 22, 1926. Shaft furnaces.-In a shaft furnace for treating zinc ores the heated gases which effect the smelting of the charge are passed upwardly mainly through the central portion of the charge, so that smelting of the charge in contact with the furnace walls is prevented. The object is secured by employing a furnace which is bellied out at A, and of which the walls of the hearth C, containing the tuyeres D, are brought closer together than usual, e.g. the width of the hearth for a furnace 5 metres high is only 65 centimetres. Additionally the discharge openings of the tuyeres are made one quarter or less of the usual size, to prevent accumulation of solid masses of reduced iron on the hearth. The ore is charged at G and preferably meets an additional air blast, supplied at F, shortly after entering the furnace. Volatilized oxides pass off by the conduit H.

Abstract: <PICT:0456174/IV/1> Artificial silk cakes after liquid treatment and before drying are subjected to substantially even compression solely by the application of inwardly directed radial pressure to the external peripheral surface of the cake the initial annular shape of which is maintained.  The treatment <PICT:0456174/IV/2> minimises differences, e.g. in dyeing properties between the inner and outer layers of the cakes.  Suitable apparatus comprises a base plate 1 to which are attached by a band 2 or by hinges or ball-and-socket joints the ends of a series of lath-like wires 3 enclosing a space in the form of a truncated cone.  A sleeve 5 also of truncated conical form surrounds the wires.  The cake 4 sits in the upper part of the conical space bounded by wires 3. Upward movement of the sleeve 5 applies to the cake an even inwardly directed compressive stress.  A rigid core may be placed inside the cake on compression to aid subsequent drying by expression of moisture from the cake.  A number of similar compressing units may be mounted on a single frame for simultaneous operation.  The cake may be laced or wrapped in a protective covering of cheese cloth before treatment and may if desired be centrifuged first.

Patent GB-876805-A (GB)
Title: Improvements in making refractory shell molds
IPC: B22C1/16
Filed: 1960-05-30
Abstract: A refractory casting mould comprises two or more mating "half-mould" shells (i.e. shells defining only part of a mould) each formed by applying a coating of a hardenable liquid refractory composition to a match plate pattern and embedding in the surface of this coating while it is still liquid a layer of granular refractory particles, hardening the resulting coating on the match plate, similarly applying successive coatings until a refractory shell of substantial thickness has been built up on the match plate, stripping the half-mould shell thus formed from the match plate, and heating the shell to a temperature high enough to fully set the refractory composition.  Satisfactory results have been obtained using a refractory composition made by dispersing a finely divided refractory such as zircon or alumina in an aqueous silica sol, which composition may in addition include a resinous polymer, e.g. a vinyl resin, for increased strength in the uncured state.  Another satisfactory composition is a dispersion of a finely divided refractory in aqueous phosphoric acid.  The composition is preferably applied by flowing it over the surface of the match plate, the excess being drained off and the granular refractory particles, e.g. silica or alumina, applied. A hardening accelerator, e.g. Portland cement when a silica sol refractory composition is used, may be mixed with the dry granular refractory.  The mould cavity in the completed shell is defined only by the first applied coating of refractory composition and accordingly this coating may with advantage be formed of a composition in which the refractory is specially selected to yield a fine surface, e.g. finely milled zircon.  The subsequent coatings may be formed of a composition in which a somewhat less fine refractory is used, e.g. fireclay grog of nominally 80-mesh particle size. Preferably, the shell is stripped directly it has hardened, sufficient strength being attained by chilling it to below its freezing temperature by the application of crushed dry ice.  The shells may either be assembled first and then heated to an elevated temperature to fully set the refractory composition or vice versa, and may be sealed together by applying thereto a coating of an hardenable liquid refractory composition similar to that used to build up each shell on the match plate.
