Patent CA-2254431-A1 (CA)
Inventor: ZHU HONG
IPC: C12N1/04
Filed: 1998-11-24
Abstract: A method and composition are described for preventing irreversible aggregation of viable microorganisms which exhibit aggregative activity upon drying. The method comprises dispersing the microorganisms in an aqueous polymer solution containing a water-soluble or water-dispersable low molecular weight polymer such that the polymer solution inhibits direct surface contact between the individual microorganisms. The polymer solution containing the dispersed microorganisms is then dried to form a dry continuous polymer matrix containing the dispersed microorganisms. This dry continuous polymer matrix is adapted to substantially totally dissolved within five minutes in cold or room temperature water and to thereby provide a reconstituted solution containing uniformly dispersed microorganisms.

Patent CA-2256424-A1 (CA)
Inventor: DICKER TIMOTHY P
IPC: A41D1/06
Filed: 1997-06-03
Abstract: In the resistive exercise pants (20), a single, wide band (50) or two spaced-apart resistive bands (4) traverse the length of the leg from the hips to the heel stirrup. Suspenders (26) attach the resistive exercise pants (20) to the shoulders, thereby holding the length of the body in dynamic tension. The front pair of resistive bands (40) bifurcate adjacent the knee (42) to conformedly curve about the calf and to form a heel stirrup (28) with the rear pair of the resistive bands. With the single resistive band (50), bifurcation occurs adjacent the knee (52) and generally progresses in a linear fashion down to the ankle where a heel stirrup (28) is formed. Hand stirrups (70) generally engage the fingers distributing tension applied by resistive bands running along the sleeve of an exercise-resistive shirt. The hand is circumscribed by an elastic band (118) with greater securement of the hand stirrup achieved by elastic finger bands (80) passing through finger interstices.

Patent CA-2260236-A1 (CA)
Title: Non-slip bandage
Inventor: BERNHARD MARK JULIAN
IPC: A61F13/02
Filed: 1997-07-10
Abstract: In the field of bandages it is known to provide a non-slip coating to one surface of a bandage. However, previous such bandages have suffered numerous disadvantages. The disclosure relates to a bandage (1) having a resiliently stretchable, non-slip coating (3) applied to it in wavy lines extending along the length of the bandage (1).  The non-slip coating is such as to provide slip resistance between the bandage (1) and human skin, to which the bandage (1) may be applied in a compressive manner. An advantageous feature of the invention is the use of a barb hook-type fastener (5, 13) the shear force of which acts in a plane approximately coinciding with that of the outer surface of the bandage (1), thereby reducing the tendency of the bandage to peel apart as a result of forces arising from the compressive application of the bandage to e.g. a human limb.

Patent CA-2272783-A1 (CA)
Title: Stack and package of laminated shingles
Inventor: QUARANTA JOSEPH
IPC: E04D1/26
Filed: 1999-05-28
Abstract: This invention is directed to a multi-layer laminated shingle, wherein each shingle layer comprises granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer.

The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.

Title: Analyses par complementation de fragments proteiques pour detecter des interactions biomoleculaires
Inventor: REMY INGRID
IPC: G01N33/58
Filed: 1998-02-02
Abstract: Nous décrivons une stratégie permettant de créer et de mettre en oeuvre des analyses par complémentation de fragments protéiques (PCA) pour détecter des interactions biomoléculaires in vivo et in vitro. La création, la mise en oeuvre et les larges applications de cette stratégie sont illustrées par un grand nombre d'enzymes, notamment par l'exemple détaillé de l'hydrofolate réductase murine (DHFR). Les peptides de fusion comprenant les fragments N et C-terminaux de la DHFR murine condensés avec les séquences formant des glissières à leucine GCN4 ont été co-exprimées chez Escherichia coli cultivée dans un milieu minimum, chez laquelle l'activité DHFR endogène a été inhibée par le triméthoprime. La co-expression des produits de fusion complémentaires a permis de nouveau la formation de colonies. La survie n'était possible que quand les fragments de DHFR étaient présents et contenaient des séquences formatrices de glissières à leucine, ce qui montre que la formation de ces dernières est nécessaire à la reconstitution de l'activité enzymatique. Les mutations ponctuelles fragment DHFR-interface d'une importance croissante (Ile vers Val, Ala et Gly) ont abouti à un augmentation des temps de doublement d'E. coli, ce qui illustre la réussite du réassemblage des fragments de DHFR plutôt que des interactions non spécifiques entre fragments. Cette analyse a été utilisée pour étudier l'équilibre et les aspects cinétiques des interactions moléculaires, notamment des interactions protéine-protéine, protéine-ADN, protéine-ARN, protéine-glucide et protéine-petite molécule, dans le but de cribler des librairies d'ADNc permettant de lier une protéine cible à des protéines inconnues ou des librairies de petites molécules organiques en vue d'étudier leur activité biologique. Les critères de sélection et de création appliqués ici ont été développés pour de nombreux exemples d'analyses par sélection clonale, d'analyses colorimétriques, fluorimétiques et autres, basées sur des enzymes dont les produits peuvent être dosés. La création de ces systèmes d'analyse, qui s'est avérée simple, permet diverses applications de la complémentation de fragments protéiques.

Title: Electrolytic restoration of concrete
Inventor: WHITMORE DAVID W
IPC: C04B41/53
Filed: 1999-09-07
Abstract: An electrolytic restoration of concrete includes an anode positioned at a surface of the concrete to be restored and the communication of a current from the anode to the reinforcing bars in the concrete as a cathode. The anode is in the presence of or carries an electrolyte so that sufficient current is provided temporarily over a sufficient period of time so that ions from the concrete are carried through the concrete and expelled into the electrolyte for extraction. The anode is provided by layer of conductive material which is particulate or fibrous so that it is an amorphous layer which can therefore follow the surface of the concrete. In a horizontal arrangement, the layer can be applied directly onto a felt mat for carrying electrolyte.  In a vertical orientation an initial layer of chopped cellulose is wetted and applied onto the vertical surface followed by the same layer carrying carbon powder so that the layer is conductive and forms the anode when connected to metal connector plates buried in the anode layer.
