Title: An improved process for the separation of the elementary constituents of air or other gaseous mixtures
IPC: F25J3/04
Filed: 1922-07-22
Abstract: 184,454. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdes G. Claude. Aug. 12, 1921, [Convention date]. Separating gaseous mixtures by liquefaction.- Tn the separation of gaseous mixtures, such as air, by liquefaction and rectification, wherein there is removed from the rectifying column a mixture containing a considerable proportion of an element (argon), boiling at a point between those of the main constituents, a quantity of gas or liquid is returned to the rectifying column which is substantially equal in amount to the mixture removed and of the same composition except for the absence of the element (argon) of intermediate boiling-point. The mixture withdrawn may be purified for the extraction of argon &c. and the residual gases returned to the rectification column. An argoniferous mixture is withdrawn from a liquid-air rectifying column A through a tube F and passed into a rectifier G. The gases from this rectifier pass through an exchanger H, compressor I, and tube J, into a nest of vaporizing tubes K in the base of the rectifier G. Part is liquefied and flows through a pipe M to the top of the rectifier, while the unliquefied portion may be withdrawn through a cock L. The liquid formed in the rectifier is siphoned into the space surrounding the tubes K, by which it is vaporized, the gas formed passing by a tube Q into the main rectifier A. Argon is withdrawn through a cock R. In a modification, the liquid formed in the supplementary rectifier is led direct into the main rectifier, and the tubes K below the supplementary rectifier are dispensed with; the tube J leads into a nest of vaporizing-tubes in the base of the main rectifier, the evaporate from the liquid formed in these tubes being led into the top of the supplementary rectifier. Specification 3326/11 is referred to.

Abstract: 912,509. Speed-responsive switches. GENERAL MOTORS CORPORATION. June 13, 1960 [July 13, 1959], No. 20644/60. Class 38 (5). In a centrifugal switch mechanism two switches are actuated in succession in response to two predetermined speeds. In the mechanism, flyweights 32, pivoted on a flange 34 of hub 28, rotate with a shaft 30 and exert an axial force on the hub, causing it to move upwards and engage the outer race of bearing 50 so as to cause axial movement of an actuator 54 in which are pins 58 which engage recesses 60 in a floating lever 62. The lever co-operates with coil springs 70, 72 of different strengths which are mounted on brackets 76, 78 which also carry switches 88, 90. At a predetermined speed actuator 54 causes the floating lever to pivot about spring 72 and overcome spring 70, so engaging the operating plunger 92 of switch 88. At a higher speed the opposition of spring 72 is also overcome and switch 90 is operated. A tachometer may be driven by the shaft. More than two switches may be employed.

Filed: 1975-05-15
Abstract: 1496964 Automatic control SINGER CO 15 May 1975 [17 Oct 1974] 20658/75 Heading G3R A gyrocompassing system with east and azimuth torquing loops for a platform, works in either a coarse align mode, where the east axis is torqued at a high rate in response to a north sensor, or in a gyrocompassing mode where, according to whether the output of the north sensor is above or below a preset level, the azimuth axis is torqued respectively at a high or low rate. In the embodiment for us in a land, sea or air vehicle, and in the coarse mode (switch S2 in position 1), the output of north sensor 12 is summed with a vertical error signal and applied to an east high rate torquer 14 to align an east gyro 17. The output of this gyro is passed via gravity compensator 28 to the input of sensor 12. With switch S2 switched to the gyrocompass mode (position 2), the north sensor output is applied to an east low rate torquer 19 and to an azimuth gyro loop. If the sensor output is within limits, the low rate azimuth torquer 23 only is energized. However, if a threshold value is exceeded in either direction relays R 1  or R 2  are activated so that azimuth high rate torquer 27 is also energized, and relay contacts 1 or 2 on amplifier 21 are closed to lock the east gyro or torque it at a high rate. In this gyrocompassing mode, east gyro 17 is controlled according to the sum of the outputs of toquer 19 and the azimuth gyro 25, as modified at 24 by the earth's angular speed. The system is such as to maintain the east gyro in an east-west direction, and the azimuth gyro in a true north direction, without the use of an external azimuth reference.

Inwardly of the immediate edge region 23c alternate narrowing points are removed in the region 23d, to secure fullness and elasticity for the leg opening. This region 23d may be extended over into the main body of the fabric. There may also be provided a reinforcement 24 which stops short of the band 23; but this reinforcement may be omitted and the band 23 extended along the entire length of the back panel 5. The blanks are knitted continuously, a draw thread 22 being interposed between successive blanks. The invention is applicable to underwear, bathing suits, tights, or the like.

Abstract: 499,823. Valve circuits for wireless reception. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. July 27,1937, No. 20740. Convention date, July 27, 1936. [Class 40 (v)] A multi-electrode valve having a single electron stream is so arranged as to give a stage of high- or lowfrequency amplification and to operate as a detector of the Barkhausen - Kurtz type. Preferably, the two electrodes most remote from the cathode are associated with the detector stage. The Figure shows a multi-electrode valve V in which the electrodes B, G4 operate as a Barkhausen-Kurtz detector with the audio-frequency output fed to the triode amplifier formed by electrodes G1, G2, by the transformer T. In a modification, Fig. 2 (not shown), the triode operates as a high-frequency amplifier whose output is applied to the Barkhausen-Kurtz detector. The electrode systems are separated by a screening grid. The resistance W and condenser C in the detector circuit produce volume control potentials as described in Specification 416,464, which are applied to the triode grid in each case as well as to the detector. The arrangement minimizes the reaction of one stage on the other consequent on the use of a common electron stream.
