Abstract: WATER ADDITION TO ENHANCE PHOSPHORIC ACID SALT              CATALYST ACTIVITY                 ABSTRACT OF THE DISCLOSURE      A method for enhancing tile catalytic activity retention of a phosphorus acid salt catalyst, especially a metal acid phosphate during the production of polyalkylene polyamines from the reaction of a feed of (i) ammonia and/or an allkyleneamine compound having at least two amino groups, such as, ethylenediamine, and (ii) an alkanolamine having at least one amino group, such as, ethanolamine.  Sufficient water is utlllzed in the feed to enhance the catalytic activity retention of the phosphorus acid salt catalyst.  When a metal acid phosphate catalyst is used, the water keeps the metal acid phosphate in the acidic state and/or returns the metal acid phosphate to the acidic state.    The re-action is conducted in tile gas phase, in the presence of a catalytically effective amount of phosphorus acid salt catalyst and at a temperature sufficient to form the polyalkylene polyamines.  Also, when the phosphorus acid salt catalyst has sustained a decrease in the activity during the production of polyalkylene polyamine, water can be added in sufficient amount to increase the activity of the catalyst.

Granted: 2001-01-30
Abstract: A medicinal composition, particularly but not exclusively for use in fluids for medical dialysis, contains, as an agent for maintaining the osmolality of the fluid, a protein hydrolysate resulting from the action of a proteolytic enzyme on the sodium caseinate fraction of milk protein. The enzyme is preferably trypsin but other proteolytic enzymes and enzyme mixtures may be used, examples being chymotrypsin, pancreatin and pronase. The method of production involves treating the sodium caseinate in aqueous medium with the enzyme at the appropriate pH and temperature for optimum enzyme activity.      The product of the enzymic hydrolysis, after filtration through a bacterial filter, adjustment of the osmolality to an appropriate level of around 300 mOsm/kg and the pH to physiological level of about 6.6 and addition of physiological salt levels, constitutes the final product.

Abstract: SELECTING, COMPOUNDING AWD TESTING          ANTIODIES FOR CANCER DIAGNOSIS AND THERAPY                              ABSTRACT      A method and an apparatus for selecting monoclonal anti-bodies or antibody fragments for use in preparing drugs for cancer detection or therapy, and a kit for compounding selected radiolabeled monoclonal antibodies or antibody fragments for in vivo cancer diagnosis and therapy.  The kit provides reagents for:  (1) the selection of monoclonal antibodies or antibody fragments which are specific to a tumor specimen; (2) compound-ing the selected antibodies with a radionuclide material; and (3) quality control testing of the resulting compound.  In the method of the invention, multiple aliquots of tumor biopsy material are fixed onto separate test areas of an apparatus which permits reaction with a panel of various monoclonal antibodies or antibody fragments known to react with tumor associated antigens.  If one or more of the antibodies or antibody fragments bind to the tumor specimen, the reagents and antibodies or antibody fragments contained in the kit may be combined with an appropriate, commercially available radionu-clide.  The resulting compounded radiopharmaceutical can then be administered to a patient for immunotherapy of the tumor or for cancer detection by diagnostic imaging of the tumor with an imaging devise to determine the extent and location of cancer-ous tumors.  A quality control kit is used to assure that the radionuclide has been combined with the antibodies or antibody fragments to produce a formulation which will bind the radioac-tivity to the patient's tumor or tumor specimen.

Title: Nitrogen rejection fractionation system for variable nitrogen content natural gas
Inventor: DAVIS RUTH A
IPC: F25J3/02
Filed: 1987-02-13
Granted: 1990-11-20
Abstract: ABSTRACT    The present invention is directed to a gas separation system for separating or rejecting nitrogen from a natural gas feed containing nitrogen, over a wide range of nitrogen concentrations, under elevated pressure using a single distillation column with two intermediate side condensers and a closed loop heat pump which reboils and partially refluxes the column.  The lower of the intermediate condensers is cooled by heat exchange with the heat pump fluid and the overhead nitrogen fraction of the column.  The upper of the intermediate condensers is cooled by heat exchange with the overhead nitrogen fraction of the column.  The process can handle feeds with increasing nitrogen composition and more than 100 vppm carbon dioxide. The process provides a high methane recovery over the entire feed range, and provides a nitrogen product having an elevated pressure suitable for recycling and reinjection into an oil or gas well to maintain well head pressure.

Abstract: HIGH-SPEED AUTOMATIC STORAGE AND RETRIEVAL SYSTEM AND APPARATUS THEREFOR                 Abstract of the Disclosure An elevated track network guides self-propelled guided vehicles (with containers thereon) from an entry location where objects enter the system, to a storage zone defined by sets of compartmentalized storage racks wherein containers filled with objects are temporarily stored, and from thence to an exit loca-tion where retrieved objects leave the system.  Each set of storage racks comprise four racks and two aisles, with two of the racks arranged back-to back between the aisles and the other two racks on opposite sides of the aisles.  Each storage rack comprises storage compartments arranged in horizontal rows and vertical columns.  A track in the track network extends through and along an intermediate row in one of the back-to-back racks (pre-empting the compartments in that row).  Each aisle accom-modates a self-propelled aisle crane which services the racks on both sides of the aisle.  Each crane comprises a chassis movable along its aisle to any column, a carriage vertically movable on the chassis to any row, and an extendable/retractable shuttle on the carriage for storing and retrieving objects in the compart-ments.  The shuttle has a "home position" intermediate the oppo-site ends of its associated racks and intermediate the tops and bottoms of those racks. A guided vehicle is directed to an unloading/loading zone on the track, which zone is adjacent the shuttle's home position and whereat objects can be exchanged between the guided vehicle and the shuttle when the latter is extended.  In one embodiment the loading zone has two regions, each accessible to only one shuttle.  One region is on the track and the other region is on a short spur track switchably con-nected to the main track inside a portion of the adjacent row of the other of the two back-to-back racks.  In a second embodiment the same loading zone is accessible to both shuttles.  In a third embodiment two separate tracks and loading zones are pro-vided, one for each aisle crane.  Control means operate the guided vehicles, aisle cranes and shuttles in desired sequences.

Abstract: METHOD AND APPARATUS FOR INDICATING PERFUSION AND      OXYGEN SATURATION TRENDS IN OXIMETRY         Abstract of the Invention The present invention discloses a method and apparatus for indicating perfusion and oxygen saturation treands in oximetry. In transmittanceand reflectance oximetry, LEDs (40, 42) are typically employed to expose tissue to light at two different wavelengths. The light transmitted through, or reflected by, the tissue is received by a detector (38) where signals proportional to the intensity of light are produced. These signals are then processed by oximeter circuitry (14, 16) to determine oxygen saturation, pulse rate, and per usiom Displays (20) are provided including a display (132, 134) of the change in the oxygen saturation during a specified interval. This display may include first (132) and second (134) trend indication displays that indicate when the oxygen saturation has either been increasing or decreasing at a rate in excess of some predetermined level. Preferably, these displays are triangular, upwardly and downwardly directed light-emitting diodes. A digital display (138) of the changein oxygen saturation may also be provided. A second type of display included provldes pulse and perfusion information, with the perfusion being displayed as a logarithmic function of the actual perfusion. This display comprises an aligned array of light-emitting diodes (136) with the number of light-emitting diodes lit at any one tlme being logarithmically proportional to the magnitude of the perfus{on. The display is automatically scaled to produce a full-scale display when the peak perfusion exceeds some predetermined level.
