Title: Production of high binding capacity magnetizable particles of controlled size used in immunoassay systems
Inventor: CHANG STEVE C-S
IPC: G01N21/78
Filed: 1992-11-05
Abstract: Abstract High binding capacity magnetized particles, which represent a significant improvement over the existing paramagnetic particles, were developed.  It was found that the use of high pH silanization yields particles that maintain the original size throughout the manufacturing process. These exhibit good binding capacity and do not require the use of hazardous solvents during manufacture.  Also, it was found to be a more efficient process, in that an 80 - 90% reduction in the use of silane was realized.
Patent CA-2083780-A1 (CA)
Inventor: HALL JACOB H
IPC: F23N5/04
Filed: 1992-11-25
Abstract: A fuel-fired, forced draft heating appliance includes a draft inducer fan having an inlet connected to a vent hood, an outlet connectable to a vent pipe, and an interior housing region in which a negative pressure is generated during normal appliance operation.          The vent hood receives hot combustion gases generated by the appliance, and has an inlet for receiving ambient dilution air that mixes with and cools the combustion gases entering the hood and subsequently  discharged  into  the  vent  pipe  by  the  fan.    A combination pressure and temperature limit control is used to sense the presence of an obstruction in either the vent pipe or the vent hood inlet and responsively shut down the appliance.  The control includes a vacuum switch external to the fan, a bimetallic disc-type temperature sensor disposed within the negative pressure fan region,  and  a  conduit  interconnecting  the  switch  and  the temperature sensor.  During normal appliance operation an ambient air flow is drawn into the fan housing sequentially through the vacuum  switch,  the  conduit  and  the  temperature  sensor.    An obstruction in the vent pipe sufficient to reduce this air flow below  a  predetermined  level  causes  the  vacuum  switch  to responsively  shut  down  the  appliance.    An  undesirably  high temperature  within  the fan,  arising  for  example  due  to  an obstruction in the vent hood inlet, causes the temperature sensor disc to block air flow through the conduit, thereby also causing the vacuum switch to responsively shut down the appliance.

Title: Molten metal distribution launder
Inventor: SKINNER ANDREW C
IPC: B22D41/02
Filed: 1993-10-29
Abstract: A low-flexure molten metal distribution launder comprises an elongated structural beam which extends over a plurality of casting stations. A  plurality of metal level sensors extend downward from the elongated structural beam to measure molten metal levels in underlying metal casting stations. A plurality of spaced U-shaped refractory hangers are supported within the structural beam to form a refractory channel. Refractory liners are received within the refractory hangers to form a molten metal trough within the structural beam. The hangers are spaced from each other and supported from the structural beam in such a way as to allow them to expand and contract relative to the structural beam without subjecting the structural beam to expansion and contraction. The walls of the refractory hangers are air-cooled to reduce heat transfer from the refractory hangers to the structural beam.
