Title: Manipulating signal spectrum and coding noise spectrums separately with different coefficients pre and post quantization
Inventor: VOS KOEN
IPC: G10L19/04
Filed: 2009-01-06
Abstract: A method, system and program for encoding speech. The method comprises receiving an input signal representing a property of speech, quantizing the input signal, thus generating a quantized output signal, prior to the quantization, supplying a version of the input signal to a first noise shaping filter having a first set of filter coefficients, thus generating a first filtered signal based on that version of the input signal and the first set of filter coefficients. Following the quantization, supplying a version of the quantized output signal to a second noise shaping filter having a second set of filter coefficients different than said first set, thus generating a second filter signal based on that version of the quantized output signal and the second set of filter coefficients, performing a noise shaping operation to control a frequency spectrum of a noise effect in the quantized output signal caused by the quantization, wherein the noise shaping operation is performed based on both the first and second filtered signal and transmitting the quantized output signal in an encoded signal. The invention overcomes the problem of coding inefficiencies and noise by applying one filter to a signal before quantization and another with different filter coefficients to a signal after quantization. Therefore, the signal spectrum and coding noise spectrums are manipulated separately.

Title: Improvements in method of and means for weighing automatically goods of various kinds
IPC: G01G17/02
Filed: 1930-03-31
Abstract: 339,914. Popov, V. D. April 5, 1929, [Convention date]. Automatic-feed weighers.-A method of weighing automatically goods of various kinds is characterized by the employment of an endless travelling belt which receives an uninterrupted stream of the goods to be weighed from any known type of uniform delivery mechanism and conveys the same to the scale pan of one or two weighing machines until the quantity deposited in the scale pan has attained the required limit of weight after which the belt is caused to reverse and to travel in a direction opposed to that in which it has hitherto travelled and is thereby caused to convey the goods into the scale pan of the second of the two weighing machines, the weighed up portion of the goods being meanwhile removed from the first scale pan which is thus prepared to receive and weigh a further portion of the goods after the next reversal of the direction of travel of the belt. As shown in connection with a cigarette-making machine, a uniform stream of tobacco is delivered from a storage and feed device A to an endless travelling belt 11 driven by one or other of two continuouslyrotating drums 17a, 17<b> against which the belt is pressed by one or other of two rollers 26a, 26<b>. These two rollers are carried by a lever 25 pivoted on a pin 24 and engaging alternately with catches 30<a>, 30<b> controlled by an electromagnet 27. The travelling belt 11 delivers alternately to the scale pans 13<b>, 13<a> of two independent weighing machines. Assuming the pan 13b has received its charge, the descent of the pan closes two contacts 14<b>, 15<b> and energizes the magnet 27 which thereupon liberates the lever 25. A spring 32, attached at one end to the lever and at the other end to the stationary part of a clutch mechanism, draws the lever into the position indicated by broken lines where it is engaged by the second catch. The upper end of the lever transfers the drive to the drum 17b and roller 26<b> so that the belt 11 is moved in the opposite direction and feeds the tobacco to the pan 13<a>. The lever 25 during its movement, acting through a link 42 and catch 48, liberates a spring-pressed arm 38 which then couples up the clutch and is carried round through 180‹ at the same time taking with it the end 34 of the spring 32 the movement being arrested when the arm 38 strikes a stop 49 connected to the lever 25 by a link 43. This action places the spring 32 in position to return the lever 25 and cause a repetition of the cycle when the pan 13<a> descends after receiving its charge. The pans may be emptied by hand, or automatic means may be provided to tip the charge out of the pans as indicated by broken lines.

Patent GB-811772-A (GB)
Title: Improvements in or relating to the extraction of metal compounds from aqueous solutions
Inventor: FLETCHER JOHN MOLYNEUX
IPC: C01G55/00
Filed: 1951-05-02
Abstract: In the extraction of a metal nitrate from a ruthenium-containing aqueous nitric acid solution by means of a water-immiscible organic solvent, the amount of ruthenium extracted is reduced by maintaining the aqueous solution before extraction in contact with a compound which reacts with ruthenium nitroso compounds to produce ruthenium compounds less soluble in the organic solvent.  The process is especially applicable to the extraction of uranyl nitrate from a solution obtained by dissolving neutron irradiated uranium in nitric acid; such solution also contains plutonium and fission products including ruthenium.  Compounds suitable for reacting with the ruthenium nitroso compounds are ferrous sulphamate, hydrazine, ferrous nitrate, and sulphamic acid.  Contact between the solution and the compound may be for 2-4 hours at 80 DEG  C.  Specified organic solvents are b ,b 1-dibutoxy diethyl ether and cyclohexanone. Plutonium remains in the aqueous phase.  In examples, the nitric acid solution is treated with ammonia to reduce the acidity and ferrous sulphamate is added, with or without hydrazine nitrate.  After reaction the solution is cooled, ammonium nitrate is added, and the solution extracted with the organic solvent.  The solvent extract is washed with an aqueous nitric acid solution containing ammonium nitrate and ferrous sulphamate as described in Specification 811,771. Uranium may be returned to aqueous solution by contacting the organic extract with water.  To effect further decontamination from ruthenium, the uranium solution may be evaporated in the presence of sodium dichromate and the process according to the invention repeated.
