Title: Improvements in or relating to the removal of siliceous cores from castings
IPC: B22D29/00
Filed: 1969-07-14
Abstract: 1,211,824. Extracting cores from castings. TRW Inc. 14 July, 1969 [18 July, 1968], No. 35411/69. Heading B3F. A method of removing a siliceous core from a metal casting comprises placing the casting in a pressure vessel, evacuating air from the vessel, introducing an aqueous caustic alkali solution into the vessel to cover the casting, heating the contents of the vessel to a temperature above the boiling point of the solution to create a superatmospheric pressure within the vessel, releasing pressure from the vessel to induce boiling of the solution trapped in the core passageways, and pressurizing the vessel with a gas atmosphere e.g. argon, helium, to terminate the boiling action. The last two steps are repeated in sequence until the core has been completely removed from the casting. An example describes the use of sodium hydroxide solution to remove fused silica cores from turbine blades.

Patent GB-822940-A (GB)
Title: Improved process and apparatus for manufacturing artificial threads
IPC: D01D5/06
Filed: 1956-11-23
Abstract: <PICT:0822940/IV (a)/1> A wet-spinning bath is fitted with a spinning tube which discharges into a tray having a double bottom.  As shown, a spinning bath 1 contains a spinning tube 2, which may be of uniform diameter, or may be of the type illustrated.  Spinning solution enters through the pipe 8 and spinneret 7.  The further end of the spinning tube is connected in liquid-tight but flexible manner to the tray 9 which has a double bottom 10.  The upper wall of the double bottom is provided with an outlet which may consist of a series of perforations distributed over the wall surface (11) or may be one or more slots extending lengthwise along the tray, and said upper wall may be bent upwards cylindrically towards the edge of the overflow 16 which may extend across the width of the tray.  Preferably said tray width (i.e. dimension at right angles to plane of the Figure) is 1.3 times the diameter of the discharge end of the spinning tube.  A discharge opening 12 connects the lower wall of of the double bottom 10 with a discharge tube 13, having a conical end 14 which fits the spinning bath discharge pipe 15.  19 is a fork supporting the spinning tube.  On a support 17 fixed to the tray 9, a pair of thread guide rollers 18 is freely rotatably mounted near the overflow.  In operation, spinning bath liquid is supplied through pipe 20 at such a rate that the liquid level in tray 9 is a little higher than the upper edge of the overflow 16, so that the overflow just operates. Owing to this difference in levels the bath liquid is propelled through the spinning tube, while the position of the guide rollers is such that the thread leaves the tray near the overflow, and so only changes its direction at a point where the liquid is more or less static.  The first thread guide roller may alternatively be arranged above the bath liquid, so that the thread passes through the spinning bath liquid entirely in a straight line.  Reference has been directed by the Comptroller to Specification 784,896.

Abstract: 429,514. Stoning fruit. ALLARDICE, D. J., and WHITESIDE, H. S., Parkhouse Street, Camberwell, London. Dec. 22, 1933, No. 36097. [Class 28 (ii)] Dried fruits, particularly dates, are stoned by placing then on a member having perforations through which pins are projected, a resilient roller pressing the flesh of the fruit downwardly around the pins, which support the stones, the stones being removed from the tops of the pins which are then withdrawn through the perforations to the general level of the member, after which the flesh of the fruit is scraped from the member. The member may be in the form of a band or plate, or in the form of a drum the pins projecting outwardly thereof. It is preferred, however, that the pins should project internally, and as shown, the pins 11 are threaded through holes in bars 12, the heads 13 of the pins being retained against the bars 12 by outer bars 14. The bars 12, 14 are mounted for radial sliding movement, to project the pins 11 into, or withdraw them from, the drum 3, in guide slots formed in end flanges of the drum. The pins 11 and bars 12, 14 are held together and are radially positioned by cams 15 between which the ends of the bars 12, 14 move during the rotation of the drum. The dates are fed into the drum by a conveyer 21 from which they are swept into the zone of operation of the rubber roller 17, by a shoot. The cams 15 are arranged so that the pins 11 are partially projected under the roller 17, and are fully projected under the rubber roller 18. The stones are removed by an adjustable semi-circular scraper 25, after which the pins are fully retracted for the removal of the pulp by the scraper 30. The stones fall on to the discharge conveyer 22 and the pulp falls on to the discharge conveyer 23. The scraper 25 is mounted for rotation about a longitudinal axis, the swinging occurring when an obstacle is encountered and is resisted by torsion springs coiled on the pivots. The drum may be mounted for rotation on ball bearings and may be open at one or both ends. The drive is effected by a pinion gearing with a toothed ring externally of the drum.
