Title: Double-oriented single crystal castings
IPC: B22D27/04
Filed: 1970-02-24
Abstract: 1276455 Directional crystallization UNITED AIRCRAFT CORP 24 Feb 1970 [13 March 1969] 8854/70 Heading BIS [Also in Division B3] A method of casting a double orientated single crystal article is characterised by establishing columnar growth in the metal in two directions at right angles to one another, increasing the solidification rate in one of the said two directions to produce doubly orientated columnar grains in said one direction, and selecting one of the grains to grow into a mould 32. The apparatus used comprises a box 12 having cooled bottom 14 and side 16 surfaces, a ceramic tube 10 surrounded by heating coils 30, and moulds 32 and 34 having a restricted opening 36. In use, the tube 10 and moulds 32 and 34 are heated to a temperature above the melting point of the alloy to be cast, water is circulated through the cooling coils 26, and the box 12, tube 10 and moulds 32 and 34 filled with molten metal. Solidification begins immediately at the chill surfaces 14 and 16 to produce columnar grains extending at right angles to these surfaces. The grains from the side chill surfaces 16 and the grains from the bottom chill surface 14 intersect and cause vertical heat flow through the horizontally orientated grains. This results in a doubly orientated columnar grain structure which grows up the tube 10 to the moulds 32 and 34. The small opening 36 in the bottom of each mould allows a single doubly orientated grain to grow into each mould, the single grain functioning as a single seed crystal. The tube 10 and moulds 32 and 34 may be positioned at an acute angle to the horizontal to obtain the desired orientation of crystal growth within each mould.

Alternatively, the feed may be effected by a screw-and-nut device operated from a source of power, or the slider may be held in adjusted position by a sliding locking-rod engaging a series of holes in the casing.

Abstract: The temperature coefficient of permeability of carbonyl-iron powder is reduced by nitriding the powder until the combined nitrogen and carbon content lies within the range 9-10.5% by weight.  The process is preferably applied to powder initially containing 0.5-2.5% of carbon and 0.4-2.6% of nitrogen, and may consist of heating the powder in a rapid flow of ammonia for 4-6 hours at 450  DEG C.  The treated powder may be mixed with a suitable proportion of untreated powder to yield a product having intermediate values of coefficient of permeability.

Abstract: 859,672. Detecting radio-activity. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 19, 1957 [March 20, 1956], No. 9000/57. Class 40(3). [Also in Group XXXVI] Pulses are classified for counting in groups according to amplitude by discriminators which in turn control the condition of flip flop circuits so that a subsequent control pulse restores the flip flops and enables the pulse to be counted. The pulse 14 to be applied to a counter appropriate to its size is fed to all of discriminators 2-5 set at successively higher levels. The pulse passes, say, discriminators 2, 3 and 4 but not 5. Pulses 27, 28, 29 are produced, differentiated at 34, 35, 36 and used to change the condition of flip flops 6, 7 and 8 which produce rectangular pulses 41, 42, 43. These pulses are terminated by a recording pulse 48 fed to line 15 which restores the flip flop. Differentiating circuits 53, 54 and 55 produce pulses 61, 62, 63 which are fed to anti-coincidence circuits 10, 11 and 12. Circuits 10 and 11 each receive two pulses and so do not register; circuit 12 receives one and so a pulse is fed to a counter connected to line 22. Fig. 3a shows an arrangement in which the bistable circuit 6 is changed from a quiescent to an active state by the application of a pulse to condenser 105 the changeover producing two pulses of opposite plurality at terminals 49<SP>1</SP>, 49<SP>2</SP>. One pulse 49<SP>2</SP> is passed to the coincidence circuit preceding it and the other to the circuit after it. The opposite polarity pulse is derived from the preceding bistable circuit and applied to terminal 50<SP>1</SP>. The recording pulse fed to a line 15 may be derived from the pulse to be counted, thus the start of the pulse may operate a bi-stable circuit which is restored when the pulse returns to its initial amplitude, the restoration producing a pulse to restore the other flip flops and to block the apparatus to any further incoming pulses. At the same time the pulse is fed through a delay circuit to restore the bi-stable circuit and in turn to open the apparatus to further pulses to be classified. An application of the invention is shown in Fig. 7 in which simultaneous occurrence of a rare and common type of radiation is to be detected. The respective types of radiation are detected by different scintillation counters 76, 77 the simultaneous occurrence of any pair of pulses being detected by a coincidence circuit 78 which produces an output to enable a selector as described above to check the amplitude of radiation from scintillator 77 if this is correct a second selector 82 is enabled to check the amplitude of radiation from scintillator 76.

Abstract: 590,290. Coated fabrics. LEVERS, J. F., BOWLES, P., and PATCHETT, R. V. April 12, 1945, No. 9150. [Class 140] [Also in Groups IX and XXXVI] A woven fabric resistance element comprises in the weft a fine resistance wire and a warp of less than 50 denier that is not adversely affected when the fabric is impregnated or coated with a film-forming substance such as cellulose acetate applied as a solution in a volatile solvent of such viscosity that on evaporation of the solvent component the fabric is stiffened by bonding of the wire wefts to the warps and characterised by the presence of unfilled interstices extending over the surface. The film-forming substance may alternatively be applied in the form of cellulose acetate filaments wound round the wire end then coalesced after weaving by treating the fabric with a solvent for cellulose acetate such as acetone. A suitable warp consists of continuous filament cellulose acetate yarns stretched and saponified before weaving thus ensuring high tensile strength as well as lightness of weight. In use as a strain gauge the fabric is conveniently in the form of a narrow woven ribbon and may be affixed to a test surface by means of a nitrocellulose dope to which the cellulose acetate employed bonds readily.

Abstract: 560,572. Controlling aircraft. PITT, H. L. July 3, 1942, No. 9252. [Class 4] An aeroplane having stabilizer surfaces mounted in apertures in the wings near the tips and tiltable about inclined axes as described in Specification 468,559, is provided with trailing edge flaps arranged in recesses in the wings aft of the stabilizers. The flaps may act as ailerons or elevators, or as flaps to control the travel of the centre of pressure as the stabilizers are tilted, and may be arranged to pivot only upwards, or both upwards and downwards, or differentially, that is the upward movement of either flap may be greater than the downward movement of the other or the upward or downward movement of either flap may be greater than the like movement of the other. The stabilizer or the wing or both may be slotted as set out in Specification 560,573. There may be more than one stabilizer arranged in each wing end part and a trailing edge flap associated with each stabilizer, or a single flap may be used to the rear of the associated stabilizers. Figs. 1 and 2 show a stabilizer 1 pivoted about an axis CC and normally fitting snugly within a recess near the end of a swept-back wing and shaped as shown. As the stabilizer is tilted, slots are opened to the front and rear of the aperture and airflow is directed over a flap 12 at the trailing edge of the wing at all angles of attack. At small angles of displacement, the stabilizer increases the lift of the wing and the flap 12 is then tilted upwardly to counteract the rearward movement of the centre of pressure. At larger angles of displacement, from 10‹ to 90‹, the lift is reduced and the stabilizers form the principal means of control. The flap 12 may be pivoted at D so as to leave a gap 14 in the lower surface of the wing when in normal position. The gap limits the amount of downward tilting of the flap but the upward movement is unrestricted. The flaps may alternatively be of the split type, or a flap having a semi-cylindrical leading edge fitting a corresponding recess in the plane may be used. The flap and stabilizer may be interconnected to move simultaneously. These control means may be fitted to model aeroplanes and gliders in which case they would be pre-set or controlled by tuned mechanical means or by radio.
