Patent CA-2130396-C (CA)
Inventor: BJORKLUND RONALD E
IPC: G09C1/00
Filed: 1994-08-18
Granted: 1998-03-31
Abstract: This  invention  deals  with  a  safe  key  distribution  and authentication in a data communication network (e.g. wireless LAN type of network).  The network includes a network manager to which are connected, via a LAN wired circuit, one or more base stations. Individual remote stations are, in turn, wirelessly connected to an installed base station.   One essential function for achieving security in such a network, is a mechanism to reliably authenticate the exchanges of data between communicating parties. This involves the  establishment  of  session  keys,  which  keys  need  to  be distributed safely to the network components.  An original and safe method is provided with this invention for key distribution and authentication during network installation, said method including using the first installed base station for generating a network key and a backbone key, and then using said first installed base station for subsequent remote station or additional base station installations while avoiding communicating said network key.

Title: Telecommunications cable
Inventor: ARPIN BENOIT
IPC: H01B7/295
Filed: 1995-03-15
Granted: 2000-10-31
Abstract: A telecommunications cable having a cable core in which each conductor is surrounded by an individual dual layer insulation of an inner layer of flame retardant polyolefin and an outer layer of fluorinated ethylene propylene. The cable is for plenum chamber usage in which corrosive smoke is to be minimized. Although the flame retardant polyolefin is a known corrosive smoke generating substance, its use in this structure is entirely suitable for plenum chamber use because little or no corrosive smoke is actually generated as the outer layer protects the inner layer from combustion.

Abstract: The present invention involves the production of large quantities of human alpha-Gal A by cloning and expressing the alpha-Gal A coding sequence in eukaryotic host cell expression systems. The eukaryotic expression systems, and in particular the mammalian host cell expression system described herein provide for the appropriate cotranslational and posttranslational modifications required for proper processing, e.g., glycosylation, phosphorylation, etc. and sorting of the expression product so that an active enzyme is produced. In addition, the expression of fusion proteins which simplify purification is described.  Using the methods described herein, the recombinant alpha-Gal A is secreted by the engineered host cells so that it is recovered from the culture medium in good yield. The alpha-Gal A produced in accordance with the invention may be used, but is not limited to, in the treatment in Fabry Disease; for the hydrolysis of alpha-galactosyl residues in glycoconjugates; and/or for the conversion of the blood group B  antigen on erythrocytes to the blood group 0 antigen.

Filed: 1994-02-22
Granted: 2000-04-04
Abstract: This invention relates to halide glasses which have particular utility as hosts for praseodymium in order to provide optical amplification by laser activity. The glasses are characterised in that die halide content is provided as a small proportion, e.g. 1-10 percent, of chloride with the remainder as fluoride. The metal content is similar to conventional ZBLAN glasses and it has been further discovered that the replacement of Al by Y and In and/or the partial replacement of Na by Cs has synergistic benefits. PR3++ constitutes a good lacing species for amplifying telecommunication signals at 1300 nm using pumped radiation at 1020 nm.

Granted: 2001-12-11
Abstract: The present application discloses a novel and advantageous method for the preparation of essentially odor-free alkali metal tetrahydroisohumulate (THIH) which proceeds through isomerization of the essential alkali metal tetrahydrohumulate (THH) intermediate, which is in turn produced by the hydrogenation with two moles of hydrogen of a starting alkali metal humulate (H) at a pH of at least 10, the intermediate THH being thus produced with relative ease and in high yields and purity, which high yields and purity carry over to the ultimate end product, namely, to the essentially aroma-, odor-, and impurity-free THIN, which end product accordingly does not require steam- stripping or other cleanup procedure as is conventional for THIH  produced from other sources or by other procedure.

Abstract: A thermostatic switch construction including a housing having a switch arm mounted for movement therein.  A bi-metallic snap disk is mounted in the housing and movable in response to temperature change with snap action between two positions of stability.  A switch arm actuating plunger is slidably mounted in the housing with its lower end adapted for contact by and snap movement by the bi-metallic snap disk.  A creep gap assembly is provided which includes a creep gap screw threadably mounted in the switch arm opposite the upper end of the plunger. Axes of the plunger and the gap set screw are in alignment. The creep space between the lower end of the set screw and the upper end of the plunger is adjustable by rotation of the set screw.  A temperature setting adjustment is provided which includes a spring member mounted in the housing with one end of the spring member in direct contact with the bi-metallic snap disk to thereby exert pressure on the disk.  An adjustment screw is threadably mounted in the housing with its end in contact with the spring member. The adjustment screw is operable when rotated to adjust the degree of pressure applied to the bi-metallic disk by the spring member. In the double throw embodiment of the invention, a first switch contact is mounted on a flexible support member and the second contact is mounted on the switch arm. The gap between the double throw contacts is adjustable by means of an adjustable screw member threaded into a stationary support opposite the first contact.

Abstract: Un raccord rapide destiné à être utilisé dans un système de perfusion de médicaments permet de déconnecter provisoirement et de raccorder ultérieurement une pompe à perfusion à un patient sans avoir à retirer une canule de perfusion transcutanée. Le raccord est monté en ligne avec une longueur de tube de perfusion et comporte un composant femelle pourvu d'une aiguille rentrée à l'intérieur et conçu pour se raccorder par coulissement à un composant mâle pourvu d'une membrane auto-obturante. Des pattes radiales situées sur le composant mâle coulissent librement dans des fentes longitudinales du composant femelle. Le composant mâle peut tourner afin de positionner les pattes selon un ajustement serré au-delà de surfaces à came entaillées de sorte qu'elles s'alignent avec des orifices à ouverture radiale du composant femelle. Lorsqu'ils sont raccordés, les composants mâle et femelle sont effectivement bloqués contre une séparation longitudinale. Toutefois, les composants mâle et femelle peuvent être séparés sans risque et facilement, et sans appliquer de forces sensiblement longitudinales, par rotation du composant mâle, qui replace ainsi les pattes dans l'alignement des fentes longitudinales du composant femelle.
