Title: Method of Casting Metal Products
Inventor: WATTS CLAUDE HARRISON
IPC: B22C21/14
Filed: 1967-03-22
Abstract: 1,159,861. Coating processes. PRECISION METALSMITHS, Inc. 22 March, 1967, No. 13378/67. Heading B3F. [Also in Divisions B5 and C3] . In a method of investment casting a shell mould 11, comprising a central sprue passage 13, individual mould cavities 14 gated at 15 into the said passage 13, and a core 12, positioned within the passage 13 to define a tubular sprue passageway 16, is placed within a vacuum chamber 25 on a platform 28 that has a hole 31 leading into the core 12 which may be hollow, and a vacuum is drawn so that the core 12 is held in position by differential gas pressure during pouring of the molten metal. Control of the degree of vacuum in the core 12 relative to that around the shell 11 is achieved by selecting an appropriate size of hole 31 by the use of plugs 33. This is necessary due to a difference in permeability of different materials used for making the core 12 and/or shell 11 They may both be made of a low permeable ceramic shell material but if the core 12 only is made of a highly permeable resin-bonded sand material the hole 31 size is increased. The core 12 may be pre-heated separately to above the temperature of the shell 11 to promote directional solidification. Alternatively the core 12 may be at a lower temperature than the shell 11 before pouring and cheaper resin-bonded sand cores used. The shell 11 may be made by coating a destructible pattern with several coats of a slurry with a drying stage between each coat. The slurry may comprise a suspension of a refractory powder such as zircon, zircon silicate, and fused silica in a binder solution comprising colloidal silica sol and small amounts of an organic film former, a wetting agent, and a defoaming agent. The wet slurry of each coating is stuccoed with coarse refractory particles of, for example, zircon, fused silica, silica, and various aluminium silicate grogs including mullite, sillimanite, fused alumina, and tabular alumina. The core 12 may be made by coating a wax form with a similar slurry as the shell 11 or by casting it in a suitable mould. A ceramic hollow core 12 is made by coating a hollow aluminium mandrel with a layer of low melting point wax, building up a refractory coating by dipping it into a refractory slurry, stuccoing with coarse refractory particles and drying, pouring hot-water in the mandrel to melt the wax and release the core and then firing the core. A suitable mould wash may be applied to a resin-bonded sand core to prevent its disintegration during casting. The vacuum chamber 25 includes gaskets 30, 40 that may be made from asbestos pads or blankets or ceramic fibre felt made from refractory fibres such as aluminasilica. The vacuum in the chamber 25 may act through the permeable shell 11 to draw the molten metal into the mould cavities 14.

Filed: 1948-05-25
Abstract: 665,351. Sound reproducing and receiving devices. BRUSH DEVELOPMENT CO. May 25, 1948 [June 17, 1947], No. 14108/48. Class 40 (iv). [Also in Group XL (b)] In a piozo-electric transducer a hydrostatically sensitive crystal (i.e. one developing similar pressures along all the major axes in response to an applied potential) is mounted on a material, e.g. a hard rubber block, which has an acoustic impedance equal to the acoustic impedance of the liquid in which the device is to operate, so that pressures existing in the liquid are applied simultaneously to all faces of the crystal and conversely alternating acoustic pressures are developed in the liquid by vibrations from all of the crystal faces. A hydrostatic piezo-electric crystal element 20 comprising a number of plates, cut perpendicular to the Y<SP>2</SP>-axis of a lithium sulphate monohydrate crystal and cemented face to face to form a cube, is mounted on a hard rubber block 21 carried by a grooved cap 22 secured to the top of a hollow tube 23 and surrounded by a cover 39 of material of suitable acoustic resistance such as rubber, the ends of which are sealed to an outer metal tube 35. The tubes are attached to a hollow base 45 which is in turn attached to a cap 53 having a filler plug 59 whereby the tubes 23 and 35 and the rubber cover 39 are filled with castor oil. Terminals in glass seals connect the crystal to a pre-amplifier 65 in a further casing attachment 60. A groove in the upper edge of the cap 22 permits the passage of castor oil beneath the rubber block 21 so that the crystal is substantially surrounded and acoustic pressure is developed in the castor oil by vibrations from all of its faces. A screen 41 protects the head of the unit. In a second embodiment, Fig. 8 (not shown), the crystal is embedded in a water-tight block of material having an acoustic impedance substantially equal to that of water, e.g. rubber and lucite.
