Patent CA-2359343-A1 (CA)
Inventor: KURUKCHI SABAH A
IPC: B01D53/14
Filed: 2000-01-28
Abstract: An inline, high-shear mixer (20) is provided in a cracked gas stream (12) upstream of a caustic tower (38) in an ethylene production unit. Spent caustic (52) is withdrawn from the bottom of the caustic tower (38) and pumped to the mixer (20), where the spent caustic mixes with and absorbs acid gas components from the cracked gas stream (12).  The spent caustic is separated from the cracked gas, forming a partially treated cracked gas stream (26). The partially treated cracked gas stream (26) is then fed to the caustic tower (38). Polymer deposition in the caustic tower (38) is reduced because polymeric material is formed when the cracked gas stream is mixed with the spent caustic and is removed before the cracked gas stream is fed to the caustic tower (38).

Patent CA-2376776-A1 (CA)
Inventor: FIANDER TODD G
IPC: B62B19/02
Filed: 2002-04-09
Abstract: The Bike Ski Binding is a system for adapting any bicycle so that it may be used in the snow. The Bike Ski Binding system consists in a short ski that is affixed to the front tire of the bicycle by a binding that is designed to attach directly to the tire. The ski used can vary in site depending on the size of the rider, the bicycle , the sort of terrain, or snow conditions being ridden. The binding is attached to the ski with screws, or could be a single molded unit combining ski and binding. The size of the binding is determined by the size of the tire to which it is attached: a two to three inch tire would typically require a binding six inches long and two and a half inches deep and a depth of two and one half inches. The Bike Ski Binding is designed so that the tire fits snugly inside the binding and is held in place by a ratcheted tensioning strap which compresses the tire into the binding for a secure attachment. A second strap, at the top of the tire, attaches the tire to the forks of the bicycle and prevents the tire from rotating while allowing a range of motion consistent with controled steering.

Abstract: A transplant/implant device for delivering at least one predetermined biologically active compound to a human or animal host system or for another  biological function in the host system is produced by genetically engineerin g vital chondrocytes or mixing chondrocytes with another type of native or genetically engineered cells or mixing chondrocytes with artificial particle s having a size comparable to the size of cells or combining at least two of t he named steps of engineering or mixing and by subjecting the chondrocytes or t he mixture comprising the chondrocytes to three dimensional culture conditions for in vitro production of cartilaginous tissue whereby the cells and/or the  artificial particles are immobilized in the cartilaginous tissue. The chondrocytes produce and maintain the cartilaginous tissue and the chondrocytes themselves or cells of another cell type immobilized in the cartilaginous tissue are able to produce and secrete the at least one predetermined compound. The artificial particles are e.g. biosensors. The chondrocytes as well as the cells of the other cell type may originate from the host or from a donor. The cartilaginous tissue proves to constitute favourable conditions for the vital cells and/or artificial particles immobilized therein and for the delivery of the predetermined compound also on a long term basis in particular by preventing or reducing unfavourable reactions by the host system such as immuno reactions or foreign-body reactions.
