Title: Method and apparatus for testing of a liquid to determine the containment therein of a lower boiling minor liquid component
IPC: G01N33/28
Filed: 1974-04-05
Abstract: 1427901 Testing of a liquid to determine the amount therein of a lower boiling minor liquid component J AICHELIN 5 April 1974 [5 July 1973] 15335/74 Heading G1B A method of determining the amount of a lower boiling minor liquid component such as water contained in a major liquid component such as oil comprises passing a predetermined volume of the liquid being tested through a heating device whereby the liquid is heated during a predetermined period of time of up to ten seconds to a predetermined temperature which is above the boiling point of the minor liquid component and below the boiling point of the major liquid component whereby any minor liquid component contained in the liquid is vapourized, the predetermined period of time being insufficient for separation of the vapourized minor component from the major component, then passing the liquid through a constricted opening and measuring the velocity of the liquid stream, and then comparing the measured velocity with a value corresponding to the velocity of the same predetermined volume of a pure liquid consisting of the major component through the constricted opening after having been heated under the same conditions. Preferably the constricted opening is a nozzle positioned vertically so that the liquid stream issues from the nozzle in an upward vertical direction to form a jet and the height of the jet is measured e.g. by a temperature sensor positioned at a predetermined distance from the nozzle. Apparatus for the above determination comprises pumping means 6, 7 adapted, in use, to bring a constant stream of the liquid being tested to heating means 11, adapted continuously to heat the test liquid to a temperature which corresponds to at least the boiling temperature of the lower boiling minor liquid constituent and a nozzle 12 for the issue of the liquid from the heating means into a measuring chamber 14, the nozzle being positioned vertically in the lower portion of the measuring chamber, which also contains a measuring sensor which is responsive to changes in the exit velocity of liquid passing through the nozzle.

Patent GB-733111-A (GB)
Title: Improvements in or relating to the preparation of titanium nitride
IPC: C01B21/076
Filed: 1953-06-03
Abstract: Finely divided titanium nitride is prepared by forming a molten mixture of reduced titanium halide and an alkali metal, alkaline earth metal, or magnesium halide, introducing anhydrous ammonia into the molten mixture to react with the reduced halide and form a finely divided precipitate of titanium nitride and separating the precipitate from the metal salt.  The reduced titanium halide is the di- or tri-halide.  The reaction is effected at 600-850 DEG  C. and the molten mixture may contain 5-50 per cent titanium halide and is agitated throughout while the ammonia as gas is introduced near the bottom of the vessel.  An inert atmosphere of argon is maintained during the reaction.  The titanium nitride of 0.01-0.1 m  size is separated by settling, cooled and leached with dilute acid, e.g. 2 per cent hydrochloric, to remove adhering chlorides.  The titanium halide, which may be fluoride or iodide, or particularly chloride or bromide may be prepared by reducing the tetrahalide with sodium or magnesium, or electrolytically.  In examples the molten mixture of halides is prepared (1) by passing titanium tetrachloride vapour into molten sodium to form a mixture of sodium chloride, and titanium di- and tri-halides; or (2) by passing the vapour into molten sodium and adding strontium chloride to the resultant mixture.

Abstract: 272,684. Graham, M., and Graham, A., (Representatives of Graham, E. A.), and Paddle, L. H. June 18, 1926. Addition to 257,309. Microphones; diaphragms.-In a telephone transmitter having a diaphragm held along a diametrical portion so that such portion cannot vibrate as described in the parent Specification, the electrically responsive portion of the transmitter is constituted by a layer of granular material through which the current passes in a direction parallel to the diaphragm. Fig. 1 shows an insulating block 3 carrying electrodes 1, 2 and a diaphragm 7 of thin sheet rubber, empire cloth, or mica clamped between rings 8, 9. The diaphragm is in addition held across one diameter by. clamping members 10, 11 one or both of which may be rigid or of soft and flexible material, and the two portions of the diaphragm may be stressed to different degrees so as to have different natural periods. In a modification, the member 10 is dispensed with and the diaphragm clamped against the granular material. An additional central electrode may also be employed and strips 15 of damping material, e.g. felt or spongy rubber, bearing on the block 3 and touching the diaphragm 7 may be provided arranged along a diameter at right angles to the clamping members 10, 11. The size of the openings 12<a>, 12b in the cover 12 and the depth of the space 12<c> between the diaphragm and cover influence the frequency response. The block 3 may be resiliently mounted in the casing 20. A layer of perforated material 25 may be clamped between the cap ring 21 and the casing, a ring 26 of soft material, such as rubber, being interposed between the cover 12 and the layer 25.

Filed: 1927-06-13
Abstract: 283,787. Dehn, F. B., (Losenhausenwerk D³sseldorfer Maschinenbau Akt.-Ges.). June 13, 1927. Testing physical qualities of materials. - Comprises a method of testing materials under any required repeated stresses, in which one end of the specimen is connected to at least two mechanical vibratory systems connected with h each other, the specimen being stressed at a frequency lying between those of the coupled systems. A machine in which the specimen is subjected to torsional stresses is shown in Fig. 1. A mass 1 forming the armature of an electromagnetic driving device is connected to one end of a rod 2 the other end of which is fixed to the base 3. A second torsion member formed by a tube 4 is connected at the upper end to the mass 1 and carries at the lower end a. mass 5 vibrating in a liquid of high viscosity. The mass' 1 is connected by a shackle 6 with one end of a specimen bar 7 the other end being connected by a shackle 8 to a cross head which may slide but cannot rotate. When the amplitude of the mass 1 is required to be very great, a spring 9, Fig. 2 is substituted for the rod 2, and the second system is formed by a horizontal bar 10 and a ring-shaped element 5 dipping into the viscous liquid. To obtain the necessary resilience between the masses 1 and 5, the tube 4 is formed of bars, suitable arrangements being described. Spiral springs or pressure gauge springs may be tested in the apparatus. In certain cases an amplifying device is applied in order that the test piece may be turned very violently. This device consists of connecting the upper end of the specimen to the fixed shackle by a spiral spring. The torsional vibrations of the mass 1 may be used to produce longitudinal or bending stresses in the specimen by the addition of a lever device.

Abstract: 476,500. Tipping-apparatus for trucks &c. GENERAL ELECTRIC CO., Ltd., and MARSHALL, C. H. June 9, 1936, No. 16125. [Class 78 (iv)] A wagon when in or near inverted position on a tippler is brought automatically into contact with vibrating means to shake out any contents which tend to adhere to its surface. In one form the vibrating means act on the side bolster which supports the wagon, and in another form they are mounted adjacent the bolster and act directly on the side of the wagon. The Figure shows one construction in which electromagnetic vibrators 12 are interspaced with permanent angle-iron connections 10, 9 between the side bolster 8 and the frame 3. The cradle 1 or top bolster 13 closes a switch in the tipped position and causes the vibrators to transmit impulses through the somewhat flexible bolster 8 to the side of the wagon thereagainst. Another form is shown in which the vibrators are mounted on a separate bar and act directly on the wagon side instead of through the side bolster. Specification 355,309, [Group II], is referred to.
