Title: Inhibition of cell adhesion by chemically-defined oligosaccharides, their derivatives, mimetics, and antibodies directed thereto
Inventor: KOJIMA NAOYA
IPC: A61K31/70
Filed: 1993-02-19
Abstract: Many tumor-associated and leukocyte-associated carbohydrate antigens function as adhesion molecules, recognized by lectins (carbohydrate-protein interaction) or complementary carbohydrates (carbohydrate-carbohydrate interaction). Common structures are found in the tumor-associated and leukocyte-associated antigens.  Metastatic potential of tumor cells as well as transendothelial migration of leukocytes was suppressed by agents, or combinations of agents of the groups: (a) carbohydrate antigens; (b) antibodies directed to those antigens; (c) oligosaccharide components of those antigens; (d) conjugates of the antigens or oligosaccharides; and (e) mimetics of the antigens or oligosaccharides. Disclosed are oligosaccharides and derivatives thereof which inhibit cell adhesion and aggregation mediated by P-selectin (GMP-140) and E-selectin (ELAM-1). Effective agents for those purposes include hybrid sugars comprising multiple epitopes, such as Lex/SLex, combination of individual sugars that comprise a hybrid sugar, which may be presented on liposomes, and antibodies or combinations of antibodies directed thereto.

Patent CA-2150646-A1 (CA)
Title: Glove box
Inventor: LANG DIETER
IPC: B25J21/02
Filed: 1995-05-31
Abstract: The glove box has a rotatably supported bottom member (2, 11, 51) which is equipped with a number of product holders (14) positioned concentrically with the rotational axis of the bottom member.  The product holders receive subassemblies or precursor products to be processed, partly within and partly without the glove box.  Typical precursor products are discharge vessels for discharge lamps, of small size, for example having discharge vessel volumes in the tenths and hundredths of a cubic centimeter, which are to be flushed with a flushing gas, and then filled with an ionizable fill.  Rotation of the bottom member delivers the products in the product holders to work- stations at which flushing, filling and other operations are carried out inside the glove box.  Simultaneously, other operations such as pinching and sealing portions of the discharge vessels can be carried out outside of the glove box by suitable outwardly located operating stations (18).  The bottom member is rotated in synchronism with the cadence or operating cycles of the respective operating stations.  This permits simultaneous processing of the products within the glove box in a protective gas atmosphere while also operating thereon outside of the glove box.
Patent CA-2151316-A1 (CA)
Inventor: KELEBEK SADAN
IPC: B03D1/02
Filed: 1995-06-08
Abstract: A multi-stage froth flotation process is provided for concentrating sulphide minerals or middlings containing non-ferrous metal values such as nickel, cobalt and copper, which co-exist with significant amounts of pyrrhotite. The process is carried out without relying on any specific reagent as pyrrhotite depressant, but rather by exploiting the natural pulp environment with low REDOX potentials generated by mild steel grinding media in the grinding step preceding the froth flotation. The concentrate from the flotation stage(s) in which the REDOX potential rises above a predetermined value, is recycled back to the grinding step and/or to preceding flotation stage(s) from which concentrate is collected as the final product or is subjected to an up-grading in a further cleaning stage.

Patent CA-2163299-A1 (CA)
Title: Refrigerating cycle
Inventor: ISHIKAWA ATUYUMI
IPC: F25B41/04
Filed: 1995-11-20
Abstract: In a refrigerating cycle (air conditioner) using mixture refrigerant, a mixing ratio of the refrigerant in a refrigerant circuit is measured by a mixing ratio detector, and a controller receives the detection signal to open a control valve when the mixing ratio of a high boiling-point refrigerant component is low, whereby the high boiling-point refrigerant stocked in a liquid reservoir is returned to the refrigerant circuit. The high boiling-point refrigerant which is supplied from the liquid reservoir through the opening operation of the control valve  is supplied from a low pressure side of a compressor into the refrigerant circuit to keep the mixing ratio of the refrigerant circulating in the refrigerant circuit to a predetermined value, thereby  preventing  abnormal  increase  of  pressure  of  the refrigerant due to variation of the mixing ratio.
