Title: Self cleaning imaging material level dispensing system
Inventor: STAUDT RHONDA L
IPC: G03G15/08
Filed: 1997-11-27
Abstract: A reproduction apparatus imaging material dispensing system has a replaceable and rotatable imaging material dispensing container from which an at least partially magnetically attractable consumable imaging material is dispensed. There is an optical imaging material level sensing system mounted outside of the container for optically detecting the imaging material inside the container through translucent walls thereof and signaling an insufficient remaining quantity of imaging material.  A magnetic brush cleaning system internally cleans imaging material from the inside of a annular translucent wall area of the container to provide and maintain relatively unobstructed such optical sensing.  It can be provided by a stationary magnet mounted outside of but adjacent to the container to attract magnetically attractable imaging material to the inside of the container wall to form a magnetic cleaning brush to clean the translucent wall annular area.  This allows a light receiving sensor on one side of the container to detecting light from a light emitter on the other side of the container through the magnetically cleaned translucent annular band.  The magnet can extend substantially the full length of the outside of the container to clean the entire interior thereof.

Patent CA-2252922-A1 (CA)
Inventor: GR NSTRAND JAN
IPC: B63B23/34
Filed: 1997-04-18
Abstract: The present invention relates to an apparatus, here designated a dock, for launching and recovery of a lifeboat, rescue boat or like small boat on a vessel, a floating platform or some fixed installation. The boat (14) is normally stored in the dock. The dock is provided with buoyant elements (1) fixed to a frame construction (3). The boat (14) is supported in a cradle (2) within the frame (3). On launching and recovery of the boat (14), the dock is lowered to a floating position on the surface of the water. In order to fix the boat (14) to the dock, a locking device (9, 15) is provided. By modifying the configuration and size of the buoyant elements, the dock is given rolling and pitching periods which as closely as possible coincide with those of the boat (14). The dock and the boat (14) will thereby behave in approximately the same manner in the sea, which makes it relatively simple to run the boat (14) into the dock even in a very heavy sea. When the boat (14) has been run wholly into the dock, it is in contact with the dock at at least two points, in which event both boat (14) and dock are fixed to one another with the aid of the locking device (9, 15). The boat (14) and the dock thus rapidly form a cohesive unit.

Patent CA-2267157-A1 (CA)
Inventor: GRANGER GALE A
IPC: A61K35/14
Filed: 1997-10-10
Abstract: This invention comprises cellular vaccines and methods of using them in cancer immunotherapy, particularly in humans. The vaccines comprise stimulated lymphocytes allogeneic to the subject being treated, along with a source of tumor-associated antigen. The allogeneic lymphocytes can be stimulated by combining or coculturing them with leukocytes obtained from the subject to be treated or form another third-party donor. Tumor antigen may be provided in the form of primary tumor cells, tumor cell lines or tumor extracts prepared from the subject. Stimulated allogeneic lymphocytes and tumor antigen are combined and administered at a site distant from the primary tumor, in order to prime or boost a systemic cellular anti-tumor immune response.  This approach overcomes the natural refractory nature of the immune system to stimulation by tumor antigens, generating a host response and potentially improving the clinical outcome.
