IPC: F15B1/24
Filed: 2000-05-30
Abstract: For a hydraulically actuated device a hydraulic power cylinder with an actuator slidably received for reciprocation within the cylinder and a piston slidably received for reciprocation within a sleeve of the actuator and defining a gas chamber on one side of the piston and a hydraulic fluid chamber on the other side of the piston so that the maximum pressure in the hydraulic fluid chamber is limited as a function of the force of compressed gas in the gas chamber acting on the piston. In this way, the maximum system pressure is a function of and substantially corresponds to the pressure of the compressed gas within the gas chamber and acting on the piston. Desirably, the pressure of the compressed gas in the gas chamber can be readily changed to change the maximum hydraulic fluid pressure.

Filed: 1998-12-30
Abstract: The invention provides a linear concatamer of at least two non-identical DNA  sequences which, by virtue of third base redundancy of the genetic code of the codons, each encode the same polypeptide of at least 30 amino acids; wherein the concatamer comprises or consists of a nucleic acid sequence which codes for an oligomer of said polypeptides in a continous reading frame. A single invariant cysteine codon may be added to one DNA sequence to encode a polypeptide derivative with a unique unpaired cysteine. The concatamer may be fused to one or more sequences encoding one or more antigens. The DNA  sequences in the concatamer may encode the compliment C3 fragment C3d or an analogue thereof. The invention also provides an expression vector comprising the concatamer nucleic acid sequence and regulatory or other sequences for expression of any oligomeric polypeptide encoded thereby, as well as a host cell comprising the expression vector. The invention can also provide a method of inducing an immune response to an antigen in the human or animal by administering a concatamer or administering a vector. Thus the invention can provide a pharmaceutical composition in the form of a DNA vaccine.

Patent CA-2328355-A1 (CA)
Inventor: SLAVOV STEFAN V
IPC: H01M8/12
Filed: 1999-04-16
Abstract: Process for gas phase electrochemical oxidation of H2S to sulfur and water or steam using an electrolysis cell (40) having an anode chamber (15, 42) on one side of a solid proton conducting membrane (17) and a cathode chamber (16, 41) on the other side of the membrane. The process comprises the steps of passing H2S-containing gas through the anode chamber to contact a catalytic anode, where it reacts to produce elemental sulfur, protons and electrons. The protons pass through the membrane from the anode chamber to the cathode chamber. An oxygen-containing gas is passed through the cathode chamber to contact the catalytic cathode, where it reacts with protons and electrons to produce water or steam. During the process, both the anode chamber and cathode chamber are maintained at a temperature of at least 120 ~C and an elevated pressure sufficient to keep the membrane moist. Sulfur is obtained in liquid or vapour form and is removed from the anode chamber while water or steam is removed from the cathode chamber. An electric current can be withdrawn from the anode and cathode. The cell can also be operated in the electrolysis mode to produce sulfur and hydrogen.

Title: Serpentine transmembrane antigens expressed in human cancers and uses thereof
Inventor: SAFFRAN DOUGLAS C
IPC: C07K16/18
Filed: 1999-06-01
Abstract: Described is a novel family of cell surface serpentine transmembrane antigen s. Two of the proteins in this family are exclusively or predominantly expresse d in the prostate, as well as in prostate cancer, and thus members of this family have been termed "STRAP" (Serpentine TRansmembrane Antigens of the Prostate). Four particular human STRAPs are described and characterized herein. The human STRAPs exhibit a high degree of structural conservation among them but show no significant structural homology to any known human proteins. The prototype member of the STRAP family, STRAP-1, appears to be a  type IIIa membrane protein expressed predominantly in prostate cells in norm al human tissues. Structurally, STRAP-1 is a 339 amino acid protein characteriz ed by a molecular topology of six transmembrane domains and intracellular N- an d C-termini, suggesting that it folds in a "serpentine" manner into three extracellular and two intracellular loops. STRAP-1 protein expression is maintained at high levels across various stages of prostate cancer. Moreover , STRAP-1 is highly over-expressed in certain other human cancers.

Title: Fast valve and actuator
Inventor: GRAY CHARLES L JR
IPC: F01L9/10
Filed: 1999-05-21
Abstract: A fast-acting valve (10) includes a valve body (12) and a spool (2) slidably mounted within the valve body (12) between first and second limit positions. Both the spool (2) and the valve body (12) have a flow passage (9, 12a) which come into alignment with the valve spool (2) at a position intermediate the first and second limit positions and spaced therefrom by a given distance (14). That given distance (14) allows the spool member to accelerate in travel from first and second limit positions to the valve open position so that the opening (and closing) of the valve occurs quite quickly. Reciprocating movement of the valve spool relative to the valve body can be provided by springs (7a, 7b) mounted in opposing ends of the valve body in cooperation with solenoids (3a, 3b) mounted on opposing sides of the valve body.
Patent CA-2333155-A1 (CA)
Inventor: MILLIKEN WALTER C
IPC: H04J14/02
Filed: 1999-02-18
Abstract: L'invention concerne une technique de communication destinée à la transmission de paquets de données dans des sous-liaisons de communication (202, 302) couplées à une unité de traitement (110). Dans un premier temps, un procédé consiste à recevoir un paquet de données provenant d'une première liaison de communication couplée à un ensemble de sous-liaisons (116). Puis les paquets sont distribués dans chaque sous-liaison (116) par une technique unique de répartition multiplet par multiplet (BBB). Logiquement, les multiplets de données associés à chaque sous-liaison (116) sont recueillis dans une tranche de données et on attribue à chaque ensemble de tranches une étiquette unique prédéterminée. Chaque tranche est ensuite transmise de manière synchrone à un récepteur (120), dans la largeur de bande regroupée de chaque sous-liaison (116) en parallèle à travers chaque sous-liaison (116) correspondante. Un récepteur (120) reçoit les tranches de données provenant de l'ensemble de sous-liaisons (116) et regroupe la largeur de bande de ces deux ou plusieurs sous-liaisons (116) de communication en une liaison de communication unique. Sauf en cas d'erreurs, un paquet est transmis dans l'ordre par utilisation de plusieurs tranches. Le système recrée le paquet original à partir d'ensembles de tranches possédant la même étiquette unique. Plus spécifiquement, le système a recours à la technique de répartition multiplet par multiplet pour extraire les multiplets appropriés de données dans chaque tranche reçue dans les sous-liaisons (116) parallèles sur la base d'une séquence de sous-liaisons correspondant aux étiquettes. Cette technique est avantageuse en ce qu'elle permet d'obtenir un équilibre optimal entre la préservation de l'ordre des paquets et la conservation des ressources du réseau.

Filed: 2001-02-12
Abstract: A nulling direct radiating array (30) that includes a main phased array (32) and a plurality of auxiliary arrays (70, 72, 74) symmetrically disposed about the main array (32). The main array (32) includes a plurality of antenna elements (34) and a beam forming system (56) that generates one or more channels made up of several pixel beams. The pixel beams from the main array (32) are connected to a pulling processor (108) along with the combined signal from the antenna elements (80) of the auxiliary arrays (70, 72, 74). An adaptive weighting network (112) and an adaptive weight generator (114) within the pulling processor (108) determine whether a jamming signal exists in the channel beam, and weight the pixel beams from the main array (32) accordingly to block the jamming signal. The auxiliary arrays (70, 72, 74) provide a wider beam aperture that is able to more narrowly define the null in the radiation pattern of the main array (32).
