Title: Radio navigation system using out-of-band pseudolites
Inventor: HOLDEN THOMAS
IPC: G01S5/14
Filed: 1997-01-31
Abstract: A system of stationary pseudolite navigation transmitters for broadcasting a GPS-like signal at a frequency F1, a non-GPS carrier frequency, is provided in the environment of GPS spread spectrum navigation signals at a radio frequency L1. A plurality of pseudolite stations (PL) broadcast a plurality of spread spectrum pseudolite navigation signals at a radio frequency F1 which are at a different frequency than the frequency L1. According to the invention, at least one reference station (REF) is provided for receiving the GPS navigation and the pseudolite navigation signals and deriving navigation correction data (Differential GPS, kinematic observations data) signals. At least one of the pseudolite stations serves as a master station (PL1) in association with each reference station. A communication link provides differential GPS and observation data signals from each reference receiver to its master pseudolite station(s) which modulate(s) the reference station observations and integrity data for broadcasting to a plurality of mobile receivers (NRX) which receive the pseudolite and GPS navigation signals including the navigation correction signals from the master pseudolite stations and produce accurate navigation information therefrom in the presence or absence of useful GPS navigation signals.

Patent CA-2247197-A1 (CA)
Inventor: HUBER DAVID JOHN
IPC: F01K25/00
Filed: 1997-02-25
Abstract: Hydrogen (2) is used as the fuel source in a power plant. The hydrogen (2) is combusted (8) in pure oxygen (1) to produce steam (71), which is then expanded in one or more power turbines (24, 26, 28), with the steam being reheated by further combustion of hydrogen with oxygen between each successive turbine (10, 12). Heat available in the steam discharged from turbines (76) is recuperated (6) by transferring it to the hydrogen and oxygen prior to combustion. Since no hydrocarbon fuel or atmospheric air is used for combustion, Nox generation is eliminated so that the only emission (77) from the power plant is water.
Patent CA-2248323-A1 (CA)
Inventor: HELLMEIER JOACHIM
IPC: B41F17/14
Filed: 1998-09-22
Abstract: In an apparatus and method of decorating articles which are  transported on article carriers  through a  treatment station along a transport path which is linear   at least over a portion of  its extent,  the article carriers  are transported  through  the linear portion of  the  transport path by a screw having a screw flight adapted to engage with a respective article carrier required to move along the linear portion of the transport path. Rotation of the screw  advances  the respective  article carrier  along  the linear transport path portion. The screw preferably rotates at  a  constant  speed  so  that  changes  in the  speed  of movement of the article carrier along the linear portion of the transport path are implemented by variations  in the screw flight pitch over the length of the screw.

Title: Mammalian subtilisin/kexin isozyme ski-1: a proprotein convertase with a unique cleavage specificity
Inventor: SEIDAH NABIL G
IPC: A61P25/28
Filed: 1998-11-04
Abstract: Using RT-PCR and degenerate oligonucleotides derived from the active site residues of subtilisin-kexin-like serine proteinases, we have identified a highly conserved and phylogenetically ancestral human, rat and mouse type-I  membrane-bound proteinase called subtilisin-kexin-isozyme-1 (SKI-1). Computer data bank searches reveals that human SKI-1 was previously cloned but with no identified function. In situ hybridization demonstrates that SKI-1 mRNA is widely distributed, e.g., in thymus, in adrenal, submaxillary and pituitary glands, in skin, teeth, ribs, intestines, cortex of the kidney and brain, cerebellum, retina, and hippocampus. Cleavage specificity studies show that SKI-1 generates a 28 kDa product from the 32 kDa brain-derived neurotrophic factor precursor (proBDNF) cleaving at an RGLT~SL  bond. In HK293 cells, proSKI-1 processed in two steps at the level of the endoplasmic reticulum and a large fraction of the membrane-bound enzyme is released into the medium. Immunocytochemical analysis shows that SKI-1 is present in the Golgi apparatus and within small punctate structures reminiscent of endosomes. In vitro studies suggest that SKI-1 is a Ca2+-dependent serine proteinase exhibiting a wide pH optimum for cleavage of proBDNF.

Abstract: The suturing system includes a cannula (20) that defines two adjacent lumens (22, 24). One lumen (24) carries a supply of anchor members (44, 46, 48, 50) that are joined together by a suture (52). The anchor members (44, 46, 48, 50) are moved by a supply rod (60), one at a time, from a lower lumen (24) to an upper lumen (22). The upper lumen (22) terminates in a sharpened tip (34) that is pierced through tissue. The single anchor member that is moved into the upper lumen (22) is then deployed into or behind the pierced tissue and the cannula is retracted. The rod (62) for deploying the anchor member also temporarily blocks movement of additional anchor members from the lower to the upper lumen (22) so that the surgeon can sufficiently tense the suture before piercing the tissue in an adjacent location and depositing a second anchor member. A series of anchor members (44, 46, 48, 50) joined by a continuous suture (52) are deposited in this manner to suture together tissue. Also provided is a gun (10) to which the cannula (20) is mounted for one-handed operation of the system.

IPC: G01N27/42
Filed: 1998-02-04
Abstract: An improved process for manufacturing a detecting unit for an electrolytic cell with rhodium electrodes. In the first step of the process, rhodium electrodes are prepared from relatively impure rhodium metal by (a) vacuum melting the rhodium metal, (b) cold drawing the rhodium metal into rhodium electrodes, and (c) cleaning the rhodium electrodes. Then, the rhodium electrodes are sealed and embedded in the glass tube of the detecting unit.  The detecting unit having the embedded rhodium electrodes is cleaned with a hot acid solution. Finally, the detecting unit is placed in the electrolytic cell. The electrolytic cell manufactured according to the process permits rhodium electrodes to be used to measure water in a sample gas comprising oxygen, hydrogen, or an inert gas; therefore, one electrode material is suitable for all applications. It is no longer necessary to provide different cells depending upon the application (sample gas containing oxygen or hydrogen or an inert gas) of interest.
