Patent CA-2211993-A1 (CA)
Inventor: JIANG WANPING
IPC: A61K47/48
Filed: 1996-01-31
Abstract: The present invention relates to the identification and characterization of a receptor associated with antigen presentation in immune responses, endocytosis, and transepithelial transport. Identification of the receptor, its characterization as having ten lectin-binding domains, and evidence of its role in the uptake and processing of oligsaccharides and oligosaccharide-decorated molecules, e.g. glycoproteins, has important ramifications for modifying immune response, and for trans-epithelial transport of molecules. The receptor, or integral membrane protein, termed herein "DEC", is found primarily on dendritic cells, but also found on B cells, brain capillaries, bone marrow stroma, epithelia of intestinal villi and pulmonary airways, as well as cortical epithelium of the thymus and the dendritic cells in the T cell areas of peripheral lymphoid organs. The murine and human counterparts of DEC have an apparent molecular mass of 205 kDa, the murine counterpart has an isoelectric point at pH 7.5. and carbohydrates comprise about 7 kDa of the total mass of murine DEC. The present invention is directed to identification of additional ligands of DEC. which can be advantageously targeted to dendritic cells and other cells that bear DEC. Targeting antigens for presentation by dendritic cells can provide for tolerance when the dendritic cells are quiescent, or for immune stimulation(i.e.,vaccination) when the dendritic cells are activated, e.g., by stimulation with a cytokine or lymphokine, such as colony stimulating factor (CSF).

Abstract: An incubation station has a carousel for receiving a plurality of test sample cards. An even temperature and air flow distribution inside the carousel and incubation of the cards over time at the proper temperature was found to be critically dependent upon air flow characteristics within the incubation station. To optimize air flow, the carousel was given an open rear side that is exposed to an air distribution table having a cover plate placed adjacent to the rear surface of the carousel. The cover plate has a plurality of elongate slots positioned in a symmetrical ring-shaped pattern in registry with the carousel. The elongate slots are positioned at an angle relative to the slots in the carousel such that each carousel slot receives air from more than one slot. An extra fan was also added to the system to increase the flow of air into the air table. Scallop features on the carousel walls also promote even distribution of air flow over the cards. The carousel may be divided into a plurality of carousel segments to increase ease of removal and insertion of the carousel into the incubation station and manufacturability of the carousel.

Filed: 1998-06-02
Abstract: A receiver (EMP1, ..., EMPn) is disclosed for receiving optical signals from an optical transmission network (NET) serving to transmit coded, multiplexed optical signals. The receiver (EMP1, ..., EMPn) includes a means (DEK1) for detecting the optical signals to be received, e.g., a Fabry-Perot filter, and processing means (O/E1, O/E2, 5) to compensate noise present in the detected optical signals by combining the detected optical signals with compensation signals. The means (DEK1) is adapted to transmit optical signals to be received and reflect optical signals not to be received. A further means (K1), e.g., an optical coupler, is provided for deriving the compensation signals from at least part of the reflected optical signals and then applying the compensation signals to the processing means (O/E1, O/E2, 5). The receiver has the advantage that the signal to be received is not contained, or is contained only minimally, in the compensation signal, so that it does not affect, or affects only insignificantly, the degree of compensation when being combined with the detected signal.

Patent CA-2250674-A1 (CA)
Inventor: WILKE RAUD A
IPC: F15B11/16
Filed: 1998-10-20
Abstract: An improved pressure-compensated hydraulic system for feeding hydraulic fluid from a variable displacement pump to multiple hydraulic actuators.  A separate valve section controls the fluid flow between the pump and a different actuator.  Each valve section has a pressure compensating valve with a valve member and poppet within a bore and biased apart by a spring.  The poppet acts as a check valve which prevents fluid flow from the actuator through the valve section to the pump when the back pressure from the load exceeds the pump supply pressure.  A pressure differential between the load-dependent pressure and the actuator pressure determines a position of the valve member which controls the pressure applied to the pump pressure control input.
