Title: A process for the recovery of germanium
Inventor: NOBILE LUCIANO
IPC: C01G17/00
Filed: 1961-01-06
Abstract: A process for recovering germanium comprises treating a germanium-containing sulphuric acid solution with an aqueous extract of tannin which contains a sodium salt of ethylene diaminotetra-acetic acid and thereafter separating the resulting germaniumcontaining precipitate from the solution.  The sulphuric acid solution of germanium may be obtained by treating a germanium-containing substance with sulphuric acid to dissolve the germanium.  Thus roasted blende may be leached with sulphuric acid to obtain the germanium solution.  In an example an aqueous sulphuric acid solution of germanium-containing sulphates of zinc, cadmium copper and iron as well as arsenic and antimony compounds is treated with a concentrated aqueous solution of powdered chestnut extract containing sodium salts of ethylene diaminotetraacetic acid to precipitate the germanium compound with tannin together with arsenic and antimony impurities.

Patent HK-94395-A (HK)
Title: A method and arrangement for frequency synthesis
Inventor: DENT PAUL WILKINSON
IPC: H03L7/107
Filed: 1995-06-15
Abstract: The present invention relates to frequency synthesis with a controlled oscillator (20) included in a phase locked loop, where the frequency of the oscillator output signal is divided (22) periodically by different integers, such that the frequency is, on average, divided by a value which is equal to an integer N plus or minus a numeric fraction whose absolute value is smaller than one. The phase position of pulses formed in this way is compared with the phase position of pulses which derive from a reference signal (10, 12), therewith forming a phase error signal. For the purpose of suppressing periodic variations of an oscillator control signal as a result of phase jitter, there is added or subtracted to the phase error signal, in a known manner, a correction value (24, 26) which is dependent on the aforementioned numeric fraction. In order to eliminate the need to multiply the correction value by a factor which is proportional to the inverted value of the integer N, the phase error signal is instead amplified with a factor N (28) prior to adding or subtracting the correction value. The loop bandwidth is also held constant in this way. <IMAGE>

Filed: 1988-01-07
Abstract: PURPOSE:To realize a safe and impartial electronic voting method by using just a single election controller having both functions of an identity confirmer and a ballot counter. CONSTITUTION:A random number generator 110, a disturbance creater 120 and a random number component eliminator 150 are prepared at the side of a voter U. While a signature function calculator 210 and a certifying function counter 230 are prepared at the side of an election controller A. Then the voting contents (v) and a random number R are disturbed for production of a voting sentence (m'). Thus both the controller A and the outsiders are unable to obtain the (v) from the (m'). While each voter U knows all voters through the mutual certification among all voters and also knows the total number of votes. Thus the controller A is unable to mix wrongly the sentences (m'). Furthermore the contents (v) altered by the A can be detected by reference to a list contents (v) opened to the public. In such a way, the safe and impartial secret voting is attained for the questionnairing, etc., in a telecommunication system.
