Patent CA-2173376-A1 (CA)
Inventor: KELLEY EDWIN A
IPC: H04B1/18
Filed: 1992-04-30
Abstract: Multiple simultaneous uses of a multi-service digital receiver are made possible with a single practical analog-to-digital converter (38) by translating the various ser-vice bands in frequency to form a single, generally contin-uous composite service band in which substantial frequency gaps (6) between the different services are eliminated. Bandwidth requirements are further reduced by a bandfolding technique in which at least one service waveband is divided about an intermediate mixing frequency (Fmix), the divided portions are overlapped so that they collectively occupy a sub-waveband with a smaller bandwidth than the original band, and the mixing frequency (Fmix) is chosen such that user-selected frequencies do not interfere with other ac-tive frequencies.  Interference between non-selected active frequencies is permissible and simply ignored.
Patent CA-2175286-A1 (CA)
Inventor: TILMAN PAUL A
IPC: B65D33/25
Filed: 1996-04-29
Abstract: A reclosable bag is formed of walls defining a closure with a mouth.  The closure includes a male profile extending along an internal surface of one of the walls and a female profile adapted to interengage with the male profile and extending along an internal surface of the other wall.  The male and female profiles are extruded from a polymeric resin.  At least one of the male and female profiles includes at least one rib of another polymeric material coextruded therewith and extending longitudinally therealong.  The polymeric material of the rib has a lower melting point than the polymeric material of the profiles, so that it will melt when a side seal is made transversely across the closure and will flow into and caulk any openings remaining after the interlocked profiles have been flattened.

Title: Method of enhancing the immunotherapeutic activity of immune cells by depletion/positive selection
Inventor: OCHOA AUGUSTO CARLOS
IPC: A61K35/12
Filed: 1995-03-14
Abstract: The present invention provides a method for enhancing the immunotherapeutic activity, e.g., antitumor activity, of immune cells by depleting immune cells of a cell subset that down-regulates the immune response, such as either CD4+  or CD8+ lymphocytes. The remaining depleted immune cell population or the separated immune cell subsets then are cultured in the presence of an antibody to a lymphocyte surface receptor, preferably an anti-CD3 monoclonal antibody (MoAb), optionally in the presence of a relatively minor amount of interleukin-2 (IL-2). These stimulated cells then are optionally additionally cultured in the presence of IL-2 without an antibody to a lymphocyte surface receptor. The present invention also provides a method of treating a mammal having tumors or immunizing a mammal against tumors by administering the stimulated depleted immune cell population or a stimulated immune cell subset to a mammal, advantageously together with an immunosuppressant, and with liposomal IL-2.  The invention further provides a method of transferring the immunity of mammals that are treated or immunized in accordance with the invention by extracting splenocytes from these mammals and administering these splenocytes to a second mammal.

Filed: 1996-11-19
Abstract: A parallel processing method for use with a graphics processor wherein graphics processing is performed by each of configured command processors efficiently in a distributed manner, with a host CPU remaining unaware of the number of command processors.  Each command group of a variable length from a host CPU is distributed from an FIFO queue to a plurality of parallelly arranged command processors for parallel processing through any free one of input FIFO queues corresponding to the command processors.          Upon command group distribution, an identical serial number is added as a command group serial number to the commands constituting the same command group.  The results of processing of individual graphics commands by the command processors are collected via output FIFO queues, which also correspond to the processors, in the order of the command group serial numbers added to the commands before the processed results are graphically drawn.

Abstract: La présente invention concerne un procédé d'assemblage de plaquettes vitro-métalliques en un empilement et de mise en forme de l'empilage, et notamment par découpe pour obtenir la forme de masse d'une de pièce telle qu'un stator d'enroulement de moteur électrique. Le procédé consiste à recouvrir chaque plaquette vitro-métallique d'un liant métal résistant à l'échauffement et ne dégageant pas de gaz, à empiler les plaquettes ainsi revêtues, à exercer une pression sur les plaquettes empilées sans laisser le liant dégorger de l'empilement de plaquettes, à laisser durcir le liant, puis à donner à l'empilement de plaquettes la forme voulue. Dans certains cas, une fois que l'empilement de plaquettes a la forme voulue, il est possible d'y adapter du câblage résistant à l'échauffement et un isolant, et de porter l'ensemble à une température suffisante pour conférer un recuit aux éléments vitro-métalliques. Le découpage des plaquettes se réalise en utilisant un mélange de substance liquide et de substance abrasive propulsé à haute pression par une tuyère. Les plaquettes ou la tuyère sont réglables de façon que la surface externe du mélange de découpe se présente perpendiculairement au plan de la surface des plaquettes.

Title: Method for treating aqueous media containing radioactive metal ions
Inventor: LECLERC OLIVIER
IPC: G21F9/12
Filed: 1995-08-02
Abstract: Method for the treatment of aqueous media or effluents containing radioactive metal ions including silver, cobalt, potassium, cesium, antimony. The method reduces the ion concentration to a value by which the radiochemical activity of the aqueous media or effluents is reduced to a level less than that laid down by regulations, enabling them to be discharged. The method involves at least one first phase in which the aqueous medium is passed through a filter (1) comprising a layer of oil coke granules, whereby at least 90 % of the above-mentioned radioactive ions can be retained. If the radiochemical activity is not lowered to below the value of the rejection threshold at the end of the first stage, the aqueous medium is then subjected to a second phase in which it is passed through a second filter provided with a graphite particle lining coated with a conductive polymer layer comprising ethereal cryptating cages.

Abstract: A mobile automated pipeline welding and quality control system comprising a gas metal arc welding carriage and a weld data monitor and acquisition unit. The welding carriage carries a welding torch, wire feed device for feeding consumable wire to the torch, an oscillator for oscillating the torch and a motorized drive mechanism for moving the carriage about a weldment. A controller for the carriage includes digital control circuitry for dosed loop control of the drive, oscillator and wire feed devices. By default, the controller operates each device at one of a plurality of pre-programmed nominal speeds selected from a mode table. The controller is responsive to drive, oscillation and wire feed speed variation signals under the control of an operator, and varies the speed of each device within speed ranges which are selected to ensure compliance with welding specifications. The monitor has voltage and current transducers for measuring current and voltage at the welding torch. The controller supplies the monitor with speed data relating to the drive, oscillator and wire feed devices. All of this information can be displayed and recorded in the monitor's memory. In addition, the monitor can compute and display the heat input into the weld based on the detected welding parameters. This information allows the operator to make minute adjustments during the welding process to ensure that a weld falls within specifications.
