Patent CA-2006353-A1 (CA)
Title: Monoclonal antibody to human carcinomas
Inventor: HELLSTROM INGEGERD
IPC: A61K47/48
Filed: 1989-12-21
Abstract: ABSTRACT The present invention relates to a novel monoclonal antibody reactive with human carcinoma cells. More particularly, the antibody of the invention is a monoclonal antibody reactive with a glycolipid cell membrane antigen on the surface of human carcinomas. The antibody displays a high degree of selectivity for carcinoma cells, showing a low degree of reactivity with certain normal human cells and no detectable reactivity with other types of tumors such as lymphomas, sarcomas or melanomas. In addition, the antibody of the invention is capable of internalizing within the carcinoma cells to which it binds and is therefore particularly useful for therapeutic applications, for example, as the antibody component of antibody-drug or antibody-toxin conjugates.
Patent CA-2006744-A1 (CA)
Title: Nucleid acids and polypeptides encoded thereby
Inventor: SOREQ HERMONA
IPC: C12N15/12
Filed: 1989-12-27
Abstract: ABSTRACT      Amplified signals in both existing and non-detected restriction fragments were observed with 3 different enzymes (PVU2, HindIII and EcoRI) in two different AMLM2 cases out of 5.  Most interestingly, the amplification of clone 14-hybridizable DNA was accompanied by amplification in BuChE positive sequences.  The fact that different sizes of the restriction fragments hybridized with the 3' probe excluded the possibility of cross-hybridization, Several of the amplified bands could be observed, with lower intensities, in the presumptive polycytemia vera (Vaguez disease) case or in one or two of the other AML cases.      The adr. sample represents a patient, currently under remission following chemotherapy treatment, whose serum and erythrocyte ChE were apparently normal in levels and biochemical characteristics.  ChE genes and clone 14 are both co-regulated and co-amplified under specific stimulants.
Patent CA-2011971-A1 (CA)
IPC: B65D81/32
Filed: 1990-03-12
Abstract: A rigid piston-type multi-cavity dispensing container for equal, simultaneous coextrusion of two or more flowable materials, such as multi-component toothpaste which, upon relative compression of the upper and lower body members, produces a single, unmixed stream of material.   As the separate materials emerge from the end of the nozzle, a tapered septum acts to guide the distinct streams into a single, unmixed stream for easy application upon a toothbrush surface.
Patent CA-2012472-A1 (CA)
Inventor: SCHUSTER GEORG
IPC: C02F1/52
Filed: 1990-03-19
Abstract: The invention involves a process as well as apparatus for the separation of arsenic from waste material. The process includes precipitation of arsenic in the form of low solubility calcium magnesium arsenates by adding calcium and magnesium compounds to the waste, separation of calcium magnesium arsenates, putting the waste in contact with an ion exchanger, regenerating the ion exchanger after reaching the charge limit, adsorptively separating the arsenic by putting the waste in contact with active carbon, and separating the charged active carbon by itself or along with precipitation products. The process allows for a separation of arsenic from waste which is hard to be treated or contains heavy metals such as lead or contains sulfates to residual amounts as low as <0.3 mg As/1.

Patent CA-2021642-A1 (CA)
Title: System for admitting steam into a turbine
Inventor: SILVESTRI GEORGE J JR
IPC: F01D9/06
Filed: 1990-07-20
Abstract: A steam turbine in which the number of shell penetrations is reduced to six, without the use of T or Y fittings, by controlling steam flow to large nozzle chambers with a single large valve, rather than two smaller size valves. Secondly, adjacent valves are oriented in opposite directions, with those valves controlling nozzle chambers in the upper casing of the turbine opening to provide downward flow. This arrangement achieves two benefits: first, it reduces the number of turns and the length of the "spaghetti" piping leading to the nozzle inlet snouts, providing a straighter and more direct route for steam flow: and secondly, the inversion of adjacent valves allows room for installation of individual servomotors for each valve, which in turn enables greater flexibility in valve actuation sequencing. The invention also provides an improved method of valve sequencing.
Patent CA-2021828-A1 (CA)
Inventor: HAIGH DAVID C
IPC: G09G5/00
Filed: 1990-07-24
Abstract: A display system has cursor definition memory for storing data defining a graphics cursor, a cache for the temporary storage of a portion of the graphics cursor for display on a display device, the cache being such that its data rate is sufficient to support the display of the graphics cursor, and control logic for updating the cache from the cursor definition memory at a slower data rate. The cache need only be large enough to store a portion of the cursor at any one time as the graphics cursor is only displayed for a fraction,  for example one-tenth,  of a scan line and the cache can be updated during the portion of  the  scan  time  when  the  cursor  is  not  displayed. Through the use of a small cache operable at the required data rate, inexpensive memory which does not support the required data rate can be used for the cursor definition memory.

Title: Method for the automatic control of the rate of supply of oxygen to a claus process plant
Inventor: LELL RAINER
IPC: C01B17/04
Filed: 1991-02-01
Abstract: ABSTRACT            An H2S-containing feed gas is partly combusted with an oxygen-containing gas in a combustion chamber of a Claus process plant so that a gas mixture is formed which contains H2S and SO2, which are reacted to produce elementary sulfur. The gas mixture leaving the combustion chamber is reacted in one or more cata-lytic processing stages and optionally in aftertreating means.  The concentrations of H2S and SO2 are measured upstream or downstream of one of the catalytic proces-sing states or upstream or downstream of the after-treating means or in such aftertreating means. The rate at which the feed gas enters the combustion chamber and the rate of supply of the oxygen-containing gas to the combustion chamber are also measured.  A controller is used to calculate from the values thus measured the rate at which the oxygen-containing gas is to be supplied to the combustion chamber in order to minimize the content of sulfur compounds in the exhaust gas.
