Patent CA-2082021-A1 (CA)
Inventor: HEGNER FRANK
IPC: C04B41/85
Filed: 1992-11-03
Abstract: To avoid any deterioration of the surface properties of objects of ceramic, glass, or a single-crystal insulat-ing material which are subjected to a vacuum temperature process, a thin layer of a spin-on glass solution with a silicon-dioxide equivalent of not more than 10% is applied to the objects by spinning or spraying prior to the vacuum temperature process. This is particularly important to avoid the strong moisture dependence of capac-itive or resistive pressure sensors having a substrate and a diaphragm to be joined together, forming a chamber sealed at least at the edge. The diaphragm is covered with a layer of silicon carbide, niobium, or tantalum serving as one capacitor electrode, or the surface portion of the diaphragm which will lie within the chamber is coated with at least one strain gage; the portion of the substrate surface which will lie within the chamber is coated with at least one additional capacitor elec-trode or, in the case of the resistive pressure sensor, not coated therewith; over the entire surface portion of the substrate and diaphragm thus coated, a thin layer of the spin-on glass solution is applied and dried;     contact is made to the capacitor electrodes or strain gages through the substrate and/or diaphragm, and sub-strate and diaphragm are brazed together by means of a ring-shaped part of active brazing material, which also serves as a spacer, or by means of a sufficient amount of active brazing paste.

Title: Process for removing hydrogen gas and non-metallic inclusions from molten aluminum or aluminum matrix composites
Inventor: DUBE GHYSLAIN
IPC: C22B21/06
Filed: 1993-01-25
Abstract: Abstract Molten unreinforced aluminum or aluminum matrix composites are treated to remove hydrogen gas and non-metallic inclusions.  A melt is placed in a treatment vessel having a vaned rotary mixing impeller and a mixture of NH4Cl powder and inert gas is injected into the melt beneath the surface of the melt with mixing and is preferably followed by a period of inert gas injection.  This results in the formation of fine bubbles which are well distributed throughout the melt, thereby causing the contained hydrogen gas and non-metallic inclusions and alkali/alkaline earth metal compounds to rise to the surface of the melt.  Dross is regularly removed from the surface leaving a purified aluminum.

Inventor: WU ALLEN
IPC: G06F7/509
Filed: 1993-11-03
Abstract: A two stage accumulator is provided for updating coefficients. The accumulator is particularly useful in an adaptive equalizer. A first stage of the accumulator receives an error word and outputs sign and carry bits resulting from the addition of the error word and an N-bit LSB portion of a larger M-bit coefficient. A second stage is responsive to the sign and carry bits for updating the (M-N) MSB's of the M-bit coefficient.        New error words are cyclically provided to the first stage during successive coefficient update cycles.      The first stage can be implemented using an N-bit twos complement adder. The second stage can be implemented using an up/down counter. A leakage function is provided by causing the up/down counter to periodically skip over increment and decrement cycles.
