Title: Improvements in or relating to electric frequency meters
IPC: G01R25/00
Filed: 1931-01-08
Abstract: 371,014. Frequency measurements- SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Jan. 8, 1931, No. 705. Convention date, Jan. 17, 1930. [Class 37.] In a frequency measuring device utilizing the change of phase in a tuned circuit when it is energized by current at a frequency other than its natural frequency, the tuned circuit comprising a condenser 3 and inductance 4 is connected to the supply frequency terminals 1, 2 in series with a resistance 5. A.D.C. measuring instrument 6 such as a moving coil instrument, is connected across the resistance 5 in series with the contacts 7 of a mechanical rectifier, such as a diaphragm rectifier, the coil 8 of which is energized from the terminals 1, 2 of the supply frequency in series with a condenser 9 or variable choking coil or other phase displacer, by a current 90‹ out of phase with the applied voltage. When the applied frequency is the same as the natural frequency of the tuned circuit, the rectifier contacts are arranged to permit the flow of equal positive and negative parts of the cycle through the instrument 6 which has a centre zero. When the applied frequency differs from the frequency of the tuned circuit the phase of the current in the latter varies with respect to the applied voltage and also the current energizing the rectifier. Accordingly, the rectifier contacts are closed for a different 180‹ part of the cycle of current in the tuned circuit and the resultant current, positive or negative, after rectification, deflects the pointer of the instrument 6 one way or the other. To eliminate the effect of potential fluctuations, the measuring instrument may be a cross coil instrument, the directing coil of which is supplied through a rectifier, e.g. a copper oxide rectifier, from the supply to be measured. Alternatively, a constant potential circuit may be used to supply the tuned circuit. The measuring instrument may be an oscillograph or an ampere-hour meter. In the latter case the measurement is converted into electrical impulses which are transmitted to distant points and there actuate an indicating instrument. A constant turning movement may be given to the meter with the measured turning moment superposed thereon, or the latter alone may act on the meter in which case the direction of rotation of the meter must also be transmitted. Alternatively, in the latter method, the energizing phase of the rectifier 7, 8 may be adjusted so that the direct current fluctuates between maximum and minimum values but does not change direction, in which case the direction of rotation of the meter is not transmitted.

Title: Improvements in or relating to froth flotation
Inventor: SCHULMAN JACK HENRY
IPC: B03D1/008
Filed: 1953-10-14
Abstract: In the froth flotation of e.g. mineral ores, 2 ethyl hexanol is used as the frother agent.  As collector agents may be used xanthates, dithiophosphates, dithiocarbamates, salts of alkyl sulphates, and particularly in the case of oxidized minerals such as malachite and azurite, ammoniated fatty acids or tall-oil.

Filed: 1943-08-13
Abstract: 567,674. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., and CHRISTIAN, D. A. Aug. 13, 1943, No. 921/45. Divided out of 567,451. Drawings to Specification. [Class 40 (iv)] A testing arrangement comprises main cleflecting means for bringing a cathode beam into a position characteristic of a wanted circuit and subsidiary deflecting means which, if the wanted circuit is busy, prevent the engagement of the beam with one part of a split target and cause its immediate deflection to the other part. Engagement of the beam with the one part initiates the seizure of the circuit and causes the deflection of the beam to the other part over which it causes a calling signal to be sent. The system described is identical with that described in Specification 567,451.

Abstract: PURPOSE:To reduce noise by outputting a non-signal voltage during the first period, and a signal voltage during the second period and detecting the difference between the non-signal voltage and the signal voltage by an HSL. CONSTITUTION:The first period for outputting the signal voltage of a VSL having a signal charge to the HSL and the second period for outputting the non-signal voltage of the VSL having no signal charge to the HSL are set, and the difference between the signal voltage and the non-signal voltage of the same VSL outputted during the different periods from the same HSL is detected. Preferably, the non-signal voltage is initially outputted and the non- signal voltage is delayed by a fixed period and a difference voltage therebetween is detected. Noise voltage to be removed is equally included in both the signal voltage and the non-signal voltage outputted from the HSL and as a result, the difference voltage therebetween does not include the noise voltage.

IPC: B22C9/10
Filed: 1995-01-06
Abstract: PURPOSE:To prevent crack, to decrease variations of density and to improve quality by pressurizing the sodium chloride powder down to a specific surface pressure first, then restoring to the initial surface pressure and repeating the a operation several times, then executing the final pressurizing. CONSTITUTION:The pressurizing method in the case of molding of a salt core 1 for casting by pressurizing of powder of sodium chloride with a hydraulic press is executed by dropping the pressure to zero during the course of pressurization from a first stage of pressurization, then again pressurizing. The pressurization method is executed by returning the pressure to zero at the point of the time the surface pressure attains 1500 to 2100kg/cm<2> after the start of the pressurization and pressurizing again. Productivity is improved by reduction of the pressurization time, the control of an oil pressure is facilitated and an initial cost is reduced if the pressurization is executed by this method. Further, the quality is improved by the decrease in the variations of the density and the generation of the crack of the salt core 1 is prevented even at a pressurization speed of >=10mm/sec.
