Abstract: A process for the preparation of potassium sulfate, sodium bicarbonate and sodium carbonate. The process involves the treatment of potash brines by the reaction of sodium chloride and potassium chloride with calcium sulfate and sodium sulfate. Syngenite precipitate is produced and a first filtrate containing sodium chloride and potassium chloride. The syngenite precipitate is treated with ammonia or ammonium ions and carbon dioxide at between 70 °C and 100 °C, with the result being calcium carbonate precipitate and a second filtrate containing ammonium sulfate and potassium sulfate. The second filtrate is cooled to a temperature of between 20 °C and 40 °C and treated with potassium chloride. A potassium sulfate precipitate results. The sodium bicarbonate is precipitated from the first filtrate.

Title: A method for forming metal matrix composite bodies with a dispersion casting technique and products produced thereby
Inventor: BURKE JOHN T
IPC: C22C21/00
Filed: 1989-10-13
Abstract: The present invention relates to a novel method for forming metal matrix composite bodies. A permeable mass of filler material is spontaneously infiltrated by a molten matrix metal. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with the filler material, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material. After infiltration has been completed to a desired extent, additional matrix metal is added to that matrix metal which has spontaneously infiltrated the filler material to result in a suspension of filler material and matrix metal, said suspension having a lower volume fraction of filler relative to matrix metal. The matrix metal then can be permitted to cool in situ or the mixture of matrix metal and filler material can be poured into a second container as a casting process to form a desired shape which corresponds to the second container. However, the formed suspension, whether cast immediately after being formed or cooling and thereafter heating and casting, can be pour cast into a desired shape.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for triggering and measuring electrochemiluminescent phenomena using a voltage waveform applied at the voltammetric working electrode which improves the precision and accuracy of measurements.  This waveform has a decreasing scan rate in the range of voltages for which electro-chemiluminescence is triggered and is substantially sinusoidal in shape in this range. The waveform results from locating the reference electrode of a potentiostat in close potential proximity to its counter electrode, and applying a uniform scanning voltage waveform at the reference electrode.  The waveform also can be synthesized digitally, converted to analog form, and applied directly to the working electrode with the reference electrode in close potential proximity to the working electrode.

Patent CA-2022153-A1 (CA)
IPC: H04L27/34
Filed: 1990-07-27
Abstract: A MODEM has a delay equalizer for receiving a trellis-coded test signal transmitted from an opposite MODEM and compensating for delay distortion of this test signal on the transmission path.  The output of this delay equalizer and the input test signal are selectively entered into a demodulator.  The output of this demodulator is assigned to predetermined signal point coordinates by a decision circuit.  A Viterbi decoder computes a branch metric representing the distance between each assigned point and receive signal point from the output signals of the decision circuit and the demodulator, and figures out the pass metrics of accumulated values based on the branch metrics so computed.  A difference signal represents the difference between the maximum and minimum values of the pass metrics from the Viterbi decoder.  A first difference signal corresponds to the pass metrics when the delay equalizer is not set for the transmission path, and a second difference signal corresponds to the pass metrics when the delay equalizer is set for the transmission path.  A control circuit compares the first and second difference signals and sets the delay equalizer out of the transmission path if the first difference signal is greater than the second, or sets the delay equalizer in the transmission path if the second difference signal is greater than the first.  Thus the MODEM automatically decides whether the delay equalizer is to be inserted in the transmission path.
