Patent CA-2297274-A1 (CA)
Title: Method and device for continuous metal charge casting
Inventor: PERRIN ERIC
IPC: B22D11/04
Filed: 1998-07-21
Abstract: The invention concerns the adjustment of the linear distribution of an injected shearing fluid, during casting, through a slot (20) provided in the cooled metal body (1)-refractory riser block (14) interface of an ingot mold for continuous metal casting charge and emerging along said ingot inner periphery, the latter being provided with clamping means for adjusting the slot thickness. The invention is characterized in that it consists in "cold" injecting through said slot (20) a regulating inflammable fluid, which is ignited on its exit from the slot, and in acting on the clamping means (25, 26, 28, 29) such that the height of the flames (39) coming out of the slot (20) is substantially constant along the whole ingot inner periphery. The invention provides the advantage of an accurate and lasting adjustment of the injected flow rate without requiring the adjustment of the injection slot thickness. The invention is applicable to continuous steel charge casting in particular.

Title: No-spill drinking cup apparatus
Inventor: SOLOMON VICTOR R
IPC: B65D47/20
Filed: 1998-08-21
Abstract: A no-spill cup (22) and valve assembly (31) which provides a secure seal against accidental liquid flow from the cup spout. The act of sucking at the cup spout creates negative pressure or a partial vacuum against a valve (31) near the spout, causing the valve to invert which unblocks an opening in the valve. When the opening is unblocked, liquid can flow freely through the valve (31) and spout. When not in the use, the valve (31) sits in a resting, closed position, with the valve pressed against a center seal-off, sealing off the opening in the valve assembly. The cup (22) assembly further allows liquid flow to be regulated between regular or maximum flow and minimal flow levels or rates by rotating the position of the valve assembly in the cover of the cup.

Title: Removing hydrogen sulfide from a gaseous mixture using iron hydroxide bonded to calcined diatomite
Inventor: WINCHESTER ERIC L
IPC: B01D53/04
Filed: 2001-02-07
Abstract: A process for removing hydrogen sulfide from a gas stream wherein the filtering media consists essentially of calcined diatomite and between 5% and 30% by weight of ferric ions bonded to the calcined diatomite.  This process is particularly efficient due to the fact that the removal of hydrogen sulfide from the gas stream is effected with a single pass adsorption performance of up to 45 mg of H2S per gram of filtering media.  Other advantages include the fact that the process has the ability to remo ve  H2S form a gaseous mixture, from a concentration of 30,000 ppm down to non-detectable levels in a single pass. Repeated in-situ regeneration of the filtering media has been proven to be a simple matter of blowing ambient air through the filtering media.
