Title: Improvements in or relating to growing crystals
IPC: C30B7/00
Filed: 1946-11-07
Abstract: Crystals of primary ammonium phosphate or of an isomorphic material are grown so as to have a predetermined resistivity, as required for piezo-electric or other purposes, by adjusting the concentration in the crystal-growing solution of one or more of the following types of contaminant ions: (a) bivalent, and (b) tetravalent negative ions of the tetrahedral type AO4 wherein the interatomic distance A-O is of the same order of magnitude as the corresponding distance in the phosphate ion or in the arsenate ion, and (c) bivalent metallic ions having radii of the same order of magnitude as the radius of the positive ion of the salt being crystallized.  The quantitative effect of barium and of sulphate ions in the crystal-growing solution is shown by a graph (Fig. 1, not shown).  Piezo-electric primary ammonium phosphate crystals of resistivity in excess of 20,000 megohms-cm. (25 DEG  C.) can be obtained starting with 75 per cent phosphoric acid containing less than 0.01 per cent SO4 and less than 0.0005 per cent Ba, and 26 per cent aqua ammonia free from barium and sulphate contamination, as the raw materials.  The ammonia is slowly added to the diluted acid in a stainless steel tank and, after adjusting the pH to about 4.35, the solution is evaporated in a glass-lined tank equipped with a glass-coated anchor stirrer until the specific gravity is 1.273 at 100 DEG  C.  The solution is then cooled to 25 DEG  C. with continuous stirring.  The resulting slurry is centrifuged and the salt washed with distilled water-the salt contains between 0.0009 and 0.0011 per cent SO4.  In order to obtain the high resistivity, piezo-electric crystals, seed crystals are planted in a solution of the salt and the solution is flowed back and forth over the seeds while the temperature is progressively lowered. After each crop of piezo-electric crystals has been gathered, about a third of the mother liquor is discarded and the remaining liquor is adjusted with fresh primary ammonium phosphate salt and pure water in order to reduce the SO4 concentration to a value suitable for growing another crop of piezo-electric crystals.  Instead of eliminating sulphate as described above, its harmful effect may be counteracted by adding tetravalent silicate ions to the crystal-growing solution. If crystals of lower resistivities are desired, ammonium sulphate can be added to the solution in quantities indicated by the graph.  The effect of barium, lead and strontium ions on the potassium salt crystals is briefly discussed.

M. ; 142, Lorraine Avenue, Upper Montclair, New Jersey, U.S.A.) Nov. 6, 1930, No. 33436. Convention date, Nov. 7, 1929. [Class 40 (ii).] Sound is reproduced from grooved sound records by causing the groove, which may be of the hill-and-dale or lateral cut type, to reflect a steady beam of light on to a light-sensitive device connected through an amplifier with a loud-speaker without the interposition of a diaphragm shutter or the like in the path of the reflected beam. The arrangement is also applicable for monitoring during recording of the groove by effecting reproduction from the groove immediately behind the cutter. The surface of the blank apart from the grooves may be coated with a non-reflecting material, and the blanks if of wax are made of white wax, or if moulded duplicate blanks they are formed of a white moulding composition to which the non- reflecting coating is applied during or after pressing. Reproduction from the record groove is effected by a light beam device on an arm traversed radially across the record by a screw 15, as shown in the Figure, driven through vertical and horizontal spindles and bevel gears from the turntable spindle which is driven by a shaft 7 from a motor 3. The device comprises two inclined casings 21 or a vertically divided casing, one casing or division housing a lamp 24 and optical system to direct a beam on to the groove which reflects the light through an optical system on to a light sensitive cell 27 in the other casing division, the cell being connected through an amplifier 39 to a speaker. Alternatively the two optical systems may be arranged in parallel like binoculars. The Figure also shows the device applied in monitoring during recording by a cutter 22 mounted on the traversing reproducer device and influenced from a microphone to cut a record groove in the blank 2 in advance of the point of light from the lamp 24.

Title: Improvements in connexion with appliances for burning liquid fuel alone or in conjunction with solid fuel and colloidal mixtures
IPC: F23D11/10
Filed: 1920-12-01
Abstract: 175,785. Morgan, G. U., and Clavey, G. A. Dec. 1, 1920. Air and steam pressure sprayers.-In a burner suitable for burning liquid fuel alone or in conjunction with solid fuel and colloidal mixtures, the valve controlling the fuel outlet is formed with a head which may be adjusted to project beyond the fuel nozzle and to cause the fuel to be spread outwardly to meet an inwardly converging stream of the atomizing-agent, or may be retracted within the nozzle so as to allow the consumption of the fuel to be increased to a maximum. Fig. 4 shows a burner comprising a double tubular walled body 10 and a cap 11 which together form a central fuel chamber 12 and an outer atomizing-agent chamber 21. Fuel is admitted to the chamber 12 through an inlet 29 and steam or compressed air to the chamber 21 through a tangential or radial inlet 30. The inner wall of the member 10 carries a nozzle 18 and the outer wall carries an adjustable screwed cap 19 surrounding the nozzle 18. The cap 19 carries an adjustable screwed cap 23 formed with induced air apertures 24. A knob 15 screwing on the cap 11 carries a valve stem 14 which is arranged in the fuel chamber 12 and is formed with a bulbous head 20 which will just pass through the aperture in the nozzle 18. When the burner is to be used as an auxiliary in a furnace fired with solid fuel the head 20 is adjusted so as to project beyond the nozzle aperture, the oil being ejected in a thin expanding sheet which meets the steam or air issuing from the nozzle cap 19 approximately at right-angles. The cap 19 is hollowed out at 22 to approximately parabolic form to provide an expansion chamber for the atomized fuel during its passage to the expanding bore in the induced air cap 23. Where a larger flame is required, as for example when the oil fuel only is used for heating a boiler, the valve is retracted until the head passes within the nozzle 19, much increased oil consumption being thereby obtained. The knob 15 and caps 19, 23 have milled operating rings and are provided wtih graduated flanges 16, 26, 28 reading against marks or scales on the cap 11, body 10, and cap 19 respectively. A by-pass consisting of an aperture 36 normally closed by a screw 35 is provided in the wall of the chamber 12 to allow steam or compressed air to be blown through the nozzle 18 to clear out any obstruction. The nozzle 18 is preferably formed of non- oxidizable steel, while the parts 10, 11 may be of brass. Fig. 6 shows a modified form of burner having a central body part 50 forming the fuel chamber containing the fluted valve stem 51. The outer body part 55 screws on the part 50, the oil and steam or air being admitted from flexible supply pipes 66, 67 through sockets 57, 58. The body parts carry conical caps 59, 60 of non-oxidizable metal and an air-regulating cap 63. A cock 70 is provided in a by-pass below the oil and steam cocks 68, 69 to allow steam to be blown through the oil passages.

A thermally actuated valve comprises a closure member 13 mounted on one end of a spindle 9 the other end of which enters a chamber 10. Variation in temperature sensed by a thermal element 11 causes movement of a piston 20 which, via a spring 21 and pin 22, causes movement of a piston 17 to vary the pressure in chamber 10 to thereby actuate the valve via spindle 9. A spring 12 urges the valve to the open position, and the effective volume of chamber 10 is varied by means of a piston 4 controlled by a knob 7 to thereby vary the temperature at which the valve closes. The chamber 10 may be filled with a pressure transmitting medium via screw 19. The knob may be used to actuate the valve directly by screwing piston 4 into abutting engagement with spindle 9. Springs 14 and 21 allow overtravel of spindle 9 and piston 20 respectively to avoid damage. In the embodiment of Fig. 1 (not shown), pistons 20, 17 are omitted, and a spring (8) allows axial movement of nut (6) once the valve has closed. The element (11) may be connected by capillary tubing to a further thermal element.
