Patent CA-2119113-A1 (CA)
Inventor: SCHAEDLICH FRANK H
IPC: G01N1/00
Filed: 1994-03-15
Abstract: Mercury Detection Method and Apparatus utilizes cartridges including gold for adsorbing mercury as an amalgam. The adsorbed mercury is desorbed by heating and passed through a Cold Vapour Atomic Fluorescence Spectrophotoreeter. Each cartridge is flushed with an inert gas, so that air and contaminants are never passed directly through the detector, so only inert gas passes through it.      To further prevent adsorption of contaminants, the cartridges are maintained at a minimum temperature, above ambient temperature and below 100°C. To enable unattended calibration, a permeation source is provided having a permeation chamber and a value assembly, including 3 separate valves, to ensure than in an off state mercury vapour cannot leak to the cartridges. To ensure an efficient use of the inert gas, its flow can be adjusted between 3 different levels, for flushing, desorption of mercury, and an idle state to maintain the apparatus purged air.
Patent CA-2121757-A1 (CA)
Inventor: LAROIA RAJIV
IPC: H04L25/03
Filed: 1994-04-20
Abstract: Intersymbol interference and precoding loss are minimized by combining the precoding and coding operations. An intersymbol interference coder uses a feedback loop to apply a dither sequence to a sequence of input signal points. The dither signal applied to each input signal point is a function of the previous signal points in the sequence.  The intersymbol interference coder implements, for example, a trellis coding operation by selecting one of several different modulo operations to determine the magnitude of the dither signal, the selection being made in response to the current trellis state. The sequence of signal points output from the intersymbol interference coder generates a valid sequence of the trellis code input to the Viterbi decoder.

Inventor: PARKER PAUL D
IPC: A01B61/04
Filed: 1994-06-28
Abstract: A double spring reset standard and spring bracket therefor particularly useful for intermediate tillage operations at depths of approximately 13 inches wherein high average draft loads are in the range of 2000 pounds.  The moment arm that the springs must resist to keep the standard from tripping during normal operation is minimized by bringing the draft force line closer to the standard pivot.  The spring bracket which must be able to resist extremely high torsional stresses is fabricated from .375 inch thick metal blanks in a single cold die operation and includes offsets and specially designed edge flanges to reduce edge stresses at the offset bends.
