Patent CA-2297448-A1 (CA)
Title: Improved inhibition of graft versus host disease
Inventor: SPANER DAVID
IPC: A61K35/18
Filed: 2000-01-28
Abstract: The development of graft versus host disease in a mammalian patient undergoing cell transplantation therapy for treatment of a bone marrow mediated disease, is prevented or alleviated by subjecting at least the T-cells of the allogeneic cell transplantation composition, in admixture with red blood cells of the donor, extracorporeally, to oxidative stress, in appropriate dosage amounts, such as bubbling a gaseous mixture of ozone and oxygen through a suspension of the T-cells. The process may also include irradiation of the cells with UV light, simultaneously with the application of the oxidative stress. After stressing, the T-cell composition is aged at reduced temperatures for at least 6 hours, before being administered to the patient. The oxidative stress induces reduced inflammatory cytokine production and a reduced proliferative response in the T-cells.

Title: Semiconductor laser excitation solid-state laser device
Inventor: SATO SHINJI
IPC: H01S3/02
Filed: 1997-12-15
Abstract: A semiconductor laser-excited solid-state laser device which is constituted by mounting a sub-mount, an LD bar, and a light guiding duct on the LD package main body of a semiconductor laser and inserting the emitting section of the LD bar into the light guiding duct. Then a gold-metallized insulating plate is welded to one side of the LD package main body and the LD bar and gold-metallized part are connected by wire bonding. The light guiding duct is constructed so that the duct can directly transmit exciting light to a laser medium and the periphery of the laser medium can be surrounded by a light condenser. When an electric current is made to flow to a cathode from the LD  package main body, the LD bar emits LD exciting light and the laser medium is excited, resulting in laser oscillation. Therefore, a highly reliable and highly efficient LD-excited solid-state laser device which can be assembled easily and can be manufactured at a low cost can be obtained.

Title: Purification en surface du graphite naturel et utilisation du graphite purifie dans une anode carbone-lithium
Inventor: NADEAU GABRIELLE
IPC: H01M4/133
Filed: 2000-02-25
Abstract: La présente invention concerne la purification physique ou chimique spécifiq ue du minerai du graphite naturel. Cette purification est appliquée spécifiquement à la surface du graphite naturel pour former un film de passivation lors de la première décharge ou intercalation du lithium dans le graphite lorsque ce dernier est  utilisé dans une pile lithium-ion. Le broyage à une petite taille avant la purification permet l'optimisation de la distribution des particules, donnant lieu à une électro de beaucoup plus homogène. Ce broyage se fait en présence des impuretés naturelles du graphit e qui jouent le rôle de micro-abrasif et donne une dureté au graphite qui fait augmenter ces propriétés mécaniques.

IPC: H04W8/12
Filed: 1998-09-04
Abstract: L'invention permet de réduire la signalisation entre un noeud de contrôle de mobiles et une ou plusieurs stations de base. Un contrôleur commun, situé au niveau de chaque station de base, commande l'attribution des ressources de communication pour les communications avec les unités de communication mobiles. Un message unique, envoyé par le noeud de contrôle mobile à au moins l'une des stations de base, contient des informations identifiant plusieurs ressources de communication au niveau de ladite station de base, par exemple les unités de canaux correspondant à plusieurs cellules de secteur desservies par la station de base. Au niveau de cette dernière, le contrôleur commun envoie le message unique auxdites ressources de communication, de façon qu'il soit finalement transmis par l'une desdites ressources aux unités de communication mobiles. La signalisation entre un noeud de contrôle et plusieurs stations de base est réduite grâce au fait que le noeud de contrôle envoie un message unique à la station de base, qui identifie à son niveau plusieurs ressources de communication, au lieu d'envoyer un message distinct à chaque ressource de communication.

IPC: G01T1/24
Filed: 2000-03-28
Abstract: In a dosimeter probe comprising a semiconductor diode or a field effect transistor for monitoring levels of radiation during medical procedures, such as the treatment of tumours, the transistor or diode is fabricated epitaxially upon a surface of a substrate and a dummy die, i.e., a slab of material similar to that of the substrate, is positioned adjacent the substrate surface so as to overlie an active region of the transistor or diode and a relatively large area of the substrate surrounding the active region. The arrangement is such that, whatever the direction from which the radiation is incident upon the active region, its path through the device before arriving at the active region will have similar characteristics to the path the radiation takes upon leaving the active region.

Title: Pneumatically driven train brake pipe pressure exhaust valve
Inventor: BEZOS ANGEL P
IPC: B61C17/12
Filed: 1997-07-02
Abstract: An EOT unit on a railcar is equipped with a microprocessor controlled regulating valve system to control pressure within the brake pipe. The system includes a microprocessor unit, a pressure transducer, a regulating valve device and an electro-pneumatic control mechanism. The microprocessor receives from the transducer an electrical signal indicative of actual brake pipe pressure and from the locomotive a brake command signal indicative of desired brake pipe pressure. The microprocessor issues electrical control signals to the mechanism when the brake command signal requires either a service brake application or an emergency brake application. The regulating valve device defines a primary passage, a branch passage, an exhaust passage, and an elongated valve bore in which a diaphragm operated piston is located above an elongated valve stem. The valve stem features two valves with the first located between the primary and exhaust passages and the second between the exhaust and branch passages. The primary and branch passages communicate with the brake pipe, and all of the passages communicate with the bore. Responsive to a control pressure provided by the mechanism to a volume above the diaphragm, the piston moves the valve stem within the bore to the extent dictated by that control pressure. For a service control pressure, the piston opens only the first valve to the extent dictated by that service control pressure. For an emergency control pressure, the piston fully opens the first and second valves to reduce the pressure in the brake pipe at an emergency rate.

Abstract: An operating unit with an automatic tool changing device comprises a tool holding device having a clutch element for the mandrel. An expanding ring driven by a slider provides latching and unlatching operations for the tool holder with respect to the mandrel. With respect to prior operating units, the inventive operating unit provides the advantage of a less size, the mechanical strength of the tool holders being the same.      Moreover, the use of a single mandrel, which is common to all of the tool holder devices, provides an operating unit which is much more simple and unexpensive than prior operating units.

Title: Method and apparatus for controlling data flow between devices connected by a memory
Inventor: FRINK CRAIG R
IPC: H04N21/643
Filed: 1999-03-31
Abstract: A memory is used as a data buffer and switch between devices producing and consuming data in combination with a separate control channel which conveys flow control information between the devices connected through the memory. The control channel includes a signal sent from a sender to a receiver indicating the amount of data written into the memory and granting the receiver permission to read data from the memory. The receiver replies with a signal indicating the amount of data read from the memory and permitting the sender to write data to the memory. This control channel reduces transfer latency incurred by managing memory coherency in applications with irregular rates of either sending or receiving data which may result from using controlled flow interconnect protocols.
