Elongated flasks, e.g. for centrifugal pipe moulds, are successively advanced through mould forming, casting and stripping stations in a closed path with their longitudinal axes horizontal, the flasks being advanced during at least a portion of the path along a downwardly inclined guideway while engaged to inhibit them gaining momentum. Empty flasks 29 are fed in pairs from sloping rails 103 into a moulding machine and from thence to centrifugal casting rolls 62. From the centrifugal casting station the flasks are fed in spaced-apart relationship by the helical impeller 54 to a stop 78, from which they are released in pairs to an elevator 85. Arms 98, Fig. 3, carrying driven rollers 124 are rotated upwardly by piston 101 to uptilt the pair of flasks while rotating them about their longitudinal axes while the mould sand is disintegrated by air, sand, grit, shot or other blast through nozzles 130, allowing the casting to leave the flask under the force of gravity and be received upon a conveyer 133. The arms 98 then return the flasks to the horizontal position and the elevator lifts them to an upper inclined railway 134. The flasks are controlled in their descent to an elevator 113 at the other end of the railway by crank-driven indexing wheels 143, 153 and a helical impeller 138. The elevator 113 lowers each flask in turn to the inclined rails 103 leading to the moulding machine, for another cycle.

Abstract: 1454237 Semiconductor devices INTERNATIONAL BUSINESS MACHINES CORP 16 May 1974 [29 June 1973] 21726/74 Addition to  1429095 Heading H1K Deleterious interface states 5 at the interface 3 between the semiconductor substrate 1 of an IGFET and the gate oxide layer 2, which is covered by a layer 4 of an insulating material such as Si 3 N 4  or Al 2 O 3 , are eliminated by implanting hydrogen ions adjacent the interface 3 to a dose of 10<SP>13</SP>-10<SP>14</SP> ions per cm<SP>2</SP> and annealing at 450-600 C. for ¢-1 hour to cause the implanted ions to occupy, and hence eliminate, the states 5. The states 5 are stated to be associated with dangling Si bonds exposed when hydrogen atoms outdiffuse through layers 2 and 4 during high temperature processing. The problems arising from the impermeability of layer 4 to diffusion of gases at relatively low temperatures are surmounted by implanting hydrogen ions, which occupy the trapping states 5, the subsequent annealing process being required to remove radiation damage from the substrate 1 and to remove additional trapping states introduced at the interface 3 by the bombardment.

Abstract: 1,189,113. Centrifugal separators. QUICKFIT & QUARTZ Ltd., D. B. WHEELOCK AND R. BUCKLEY. 2 May, 1967 [17 May, 1966], No. 21939/66. Heading B2P. An apparatus for centrifugally separating the components of a mixture of substances, e.g. a mixture of a particulate solid and a liquid or a mixture of two or more liquids, comprises a basin 2 driven by an electric motor 5 and including a central well 3 opening into a surrounding chamber 4 which is adapted to be traversed laterally by a tubular scoop 11 with an end opening facing against the direction of rotation of the mixture whereby a centrifugally separated component of the mixture can be removed from the chamber and led via a rigid duct 6 into a receiver (not shown). The duct 6 is mounted in spring clips 7 carried on a chassis 8 provided with a rack 8a actuable by a pinion 9 driven by a reversible synchronous motor 10 so as to reciprocate the duct 6. Alternatively the pinion 9 may be driven manually. The duct 6 is axially adjustable on the clips 7 so that the area of traverse of the scoop 11 may be varied. To assist in removing one or each liquid stratum and/or a particulate solid stratum from the chamber 4 the duct 6 is connected by means of a T-piece 11a to a vacuum line 12 which is put in communication with a vacuum source, at a predetermined point of the traverse of the scoop in the chamber, by means of an extension 13 of the rack 8a which is formed with cam surfaces 14, 15. The surface 14 normally bears on a resilient portion of the line 12 in the region where the latter extends between two blocks 16 to close the line to the vacuum source, the surface 15 serving to relieve the pressure on the line 12, and open it to the vacuum source at the predetermined point in the traverse of the scoop. A cleaning fluid may be introduced into the basin 2 at the end of a scooping-up operation for removing the last traces of separated solids from the basin.

Filed: 1953-08-10
Abstract: 738,622. Stirring appliances. BABCOCK & WILCOX CO. Aug. 10, 1953 [Aug. 14, 1952], No. 22069/53. Class 86. [Also in Groups XI, XII and XXXV] A device for stirring electrically-conductive fluid material consists of a rotatable magnetic field member including a succession of peripherally-disposed magnetic poles of alternately opposite polarities and having a peripheral pole pitch of such length that, on operation of the field member, a moving field of substantial strength penetrates into the fluid material disposed closely adjacent the rotatable field member, and a shroud of non-magnetic material surrounding the field member. As described, molten metal in tiltable ladle 4 (see Group XII), is circulated along a path 41 under the influence of a rotating electromagnetic field member 30 having peripherally disposed poles 40, situated adjacent an upwardly sloping portion 32 of the bottom of the ladle. The ladle consists of a refractory lining 8 within a metal support structure 7 of which the bottom 33 is given a high resistance to eddy currents, as by employing a slotted, laminated or slatted construction in metal of high resistivity. The bottom 33 may be of non-magnetic metallic material, such as stainless steel. If desired, the horizontal portion of the bottom 33 may be made highly electrically and magnetically conductive to screen the rear portion of the bath 9 against the inductive effect of the magnet 30 to prevent reverse flow up the rear wall of the ladle. The field member 30 is peripherally surrounded by a thin non-magnetic open-ended cylindrical metal shroud 65 through which cooling air is drawn by a fan rotating coaxially with the field member 30. A non-magnetic scraper 66 keeps the shroud 65 clear of foreign iron or steel material. The windings of the field member 30 are excited by current supplied through sliprings from a battery and rheostat, Fig. 2 (not shown). During pouring of the metal through the spout 11 the windings of the field member 30 may be overloaded to produce a stronger stirring action which keeps the surface slag away from the pouring spout 11. The ladle 4 is provided with heating electrodes 10. In a modification, Fig. 3 (not shown), the rotatable field member is located beneath an arch formed in the bottom of a shallow melting furnace, and with an elongated furnace, two or more spaced, similarly-arranged inductors could be used.
