Abstract: ABSTRACT OF THE DISCLOSURE            In foundry core-blowing, a blow box snugly fits a plunger which moves through it during the blowing step.  In effect,  the  plunger pushes all of the fluidized sand  mix out  of  the blow box and into the core box.   This  solves problems  which have long empeded the use of quick  setting sand  mixes in blowing of cores and the  like.   With  more conventional  sand mixes better and more uniform packing of the  sand in the mold is believed  to  be  achieved.   Two measuring feeders are provided supplying two different sand mixes  which are non curing when separate but fast  setting when mixed.  They are mixed in a rapid mixer, dumped into a charging  tube which quickly dumps the mix into a blow box.          The  plunger  moves  through the  charging  tube  and  then through  the  blow  box,  cleaning both and aiding  in  the blowing  of all of the sand mix into the mold or  the  blow passage  leading to it.   This may be in the form of a blow tube which has at its tip an internal lip which breaks  off any residue or plug retained within this tube.

Abstract: Abstract of the Disclosure A pair of differential amplifier stages are connected in cascade to form a multistage amplifier for signal amplification purposes.  The base-emitter paths of current source transistors which establish the operating currents for the respective stages are connected in series across a common source of forward bias voltage.  The collector-emitter path of an additional transistor is shunted across the base-emitter path of one of the current source transistors.  As biasing of the additional transistor is varied, the distribution of gain between the respective cascaded stages is altered substantially without disturbance of the overall gain of the multistage amplifier.

Abstract: ABSTRACT                 BROADCASTING ENCRYPTED SIGNALS      Binary signals for broadcasting are encrypted by a pseudorandom bit-stream generated from a secret key and an initialisation bit-stream.  The initialisation stream is multiplexed, broadcast, recovered at the receiver and used to regenerate the pseudorandom stream for decrypting.  The multiplexing ensures synchronisation.    Each pseudorandomiser, at transmitter and receiver, has a ciphering engine containing the key. 64-bit words are pseudorandomised and fed back from the output register and the pseudorandomised words are sent bit-by-bit on line as the encryption stream.  The random number generator produces an initialisation stream which is formed into words by initialisation register and periodically transferred to input register by control codes from the unit.    Control codes, on line, and initialisation stream, on liner are multiplexed and broadcast.       Each receiver separates the control pulses and initialisation stream whereby the register obtains initialisation words and microprocessor regenerates the description stream.

Abstract: Abstract of the Disclosure An echo canceler is proposed wherein nonlinear characteristics of a D/A converter are eliminated so as to effectively cancel an echo (leakage component). Random access memories are used to allow decrease in the dimensions of the memories and hence in the overall circuit so that a compact LSI echo canceler can be easily obtained.  In an embodiment an echo canceler is provided which performs convergence in a multiple step manner using a plurality of adaptive digital filters.  The adaptive digital filters are sequentially operated to supply data to the corresponding D/A converters.  The echo signals are sequentially cancelled in a stepwise manner. As a result, a required number of bits of D/A converters is decreased. A compact LSI echo canceler can be readily obtained.

Title: Process for the froth flotation of complex metal  compounds
Inventor: HEIMALA SEPPO O
IPC: B03B1/04
Filed: 1983-10-27
Granted: 1987-06-02
Abstract: Abstract The invention relates to a process for the froth flotation of complex ores. In accordance with the invention, froth flotation is usually carried out by using a collector and froth flotation conditions in which it has been calculated in advance that the said mineral and the collector form stable surface compounds. The conditions include the potential of the system, the concentration of the collector, the pH, and other physical factors. According to the invention it has been observed that by adjusting the potential and the concentration of the collector separately for each mineral, each mineral can be frothed out separately from the slurry, the process being in this case specific. When so desired, the different minerals of the slurry can also be frothed simultaneously by selecting the conditions so that the Pourfaix-type diagrams of all minerals overlap under the conditions in question.

Abstract: "IMPROVED DIGITAL PSK MODULATOR FOR MODEM"               Abstract of the Disclosure An improved four-phase differential phase shift keyed modulator for use in a modem is shown. A microprocessor (15) generates two vectors of equal frequency and equal magnitude, but different relative phases, by reference to a cyclic sine table contained in a read only memory (22).  Values of the two vectors are summed and provided as an output (32) to a digital to analog converter (35). The phase shift of the carrier in a phase plane with reference to a predetermined reference phase (86) shows that the path taken by a vector in the phase plane defines a straight line (88) between two phase values by which dibits are encoded.  The result is lower out-of-band transmitted signals resulting in a relatively simple transmit filter (37).

Abstract: A METHOD OF PRODUCING LEVEL OFF DP MICROCRYSTALLINE          CELLULOSE AND GLUCOSE FROM LIGNOCELLULOSIC MATERIAL.     ABSTRACT     Microcrystalline cellulose has many applications in the pharmaceutical, food, paper and structural composite industries. Level off DP (Degree of Polymerization) microcrystalline cellulose is made up of a chain of about 250 glucose molecules in the form of a microcrystal.  In nature, several microcrystals are hinged together and surrounded by amorphous cellulose to form a cellulose microfibril.  If the amorphous cellulose is removed, the resultant product is called level off DP (degree of polymerization) microcrystalline cellulose.  When lignocellulosic material is processed according to applicant's earlier processes (Canadian Patents 1,096,374 and 1,141,376), the dissociated material is partitioned by removing the lignin and the xylan leaving a low DP ( 320) cellulose fraction.  This material can be converted to level off DP microcrystalline cellulose and glucose by soaking the cellulose in an acid solution, dewatering it, returning the acid impregnated cellulose to the reactor, introducing high pressure steam (300-700 psi) and when substantially all of the material reaches a temperature of the order of 215 degrees celcius, releasing it instantly to atmosphere.  This procedure will produce a mixture of level off DP microcrystalline cellulose and glucose.  If the temperature of the material is allowed to reach a uniform temperature of 234 degrees celcius plus a small allowance for measurement error, before instant release to atmosphere, the procedure will produce substantially all glucose.

Abstract: Abstract of the Disclosure A frequency converting circuit converts an input frequency into a desired frequency.  To obtain the desired frequency, a first frequency converter converts the input frequency, by using an output frequency of a first local oscillator, into an intermediate frequency.          The first local oscillator is a voltage controlled oscillator as a part of a phase locked loop circuit.          A second frequency converter converts the intermediate frequency into the desired frequency by using an output frequency of a second local oscillator.  A phase comparing circuit compares the phase of the output signal of the second frequency converter with that of the output signal of the first local oscillator.  The phase comparing circuit is contained in the phase locked loop circuit.  The result of the comparison is used for controlling the oscillating frequency of the first local oscillator.
