Patent CA-2197664-A1 (CA)
Inventor: CEDRO VITO III
IPC: C01F7/784
Filed: 1995-01-06
Abstract: There is provided an improved method for making synthetic hydrotalcite by first reacting powdered magnesium oxide with a high surface area, transition alumina in a solution or suspension to form a meixnerite-like intermediate. This intermediate is then contacted with an anion source such as an acid, and most preferably carbon dioxide, to form the layered double hydroxide which is separated from the suspension by filtering, centrifugation, vacuum dehydration or other known means. On a preferred basis, the transition alumina combined with activated magnesia consists essentially of a rehydratable alumina powder having a surface area of 100 m2/g or greater. To make related double hydroxide compounds, still other reactants such as bromides, chlorides, boric acids, or salts thereof, may be subsituted for the carbon dioxide gas fed into this suspension.

Title: Isolation of multimedia signals for transmission and processing within a multimedia terminal
Inventor: TOUTANT ROGER P
IPC: G06F13/40
Filed: 1997-07-11
Abstract: As signal bandwidths increase in multimedia terminals, reducing latency and jitter imposed upon signals transmitted within the terminals is becoming increasingly important.  Present architectures do not isolate multimedia, time-sensitive signals from other, or unrelated signals, resulting in a negative impact on signal transmission, and consequently terminal performance.  This invention arises from a recognition that improved performance could result from isolating the two types of signals. According to the invention there is provided a multimedia terminal for processing multimedia signals such as video and audio signals. The multimedia terminal has a host processor, latency and jitter insensitive and latency and jitter sensitive devices, and an isolation device between the latency and jitter insensitive devices and at least some of the latency and jitter sensitive devices is operative to pass primarily low bandwidth signals.

Inventor: AUSTIN ERIC L
IPC: B05C11/10
Filed: 1998-02-27
Abstract: A dispensing pump for dispensing liquid, particularly suitable for dispensing two-part epoxy for encapsulation of integrated circuits, includes a pumping chamber in communication with a nozzle via a three way valve, the pumping chamber including an outlet, an internal volume, a pair of spaced directional seals located away from the outlet, an open volume reciting between the seals and an external port opening the open volume to atmosphere. A stepped plunger extends axially within the pumping chamber, with a first portion sized to be received and aligned through the first directional seal, the plunger being movable to move the first portion toward the outlet to close off the internal volume at the second seal. The second portion of the plunger is relatively smaller in transverse cross-sectional dimension than the inside diameter of the second seal, to cooperate with the port to promote fluid removal from the internal volume during initial filling and priming of the pumping chamber. Once filled and primed, the plunger causes positive volume displacement of liquid from the pumping chamber and out of the nozzle, with very good repeatability and high fluid flow rates, independent of material viscosity, and/or temperature or viscosity changes. For refilling, the plunger is retracted from a volume which corresponds to the volume of material refilled into the internal volume.
