Title: Waterproof foot covering
Inventor: CHEN EDDIE
IPC: A43B3/02
Filed: 1998-12-09
Abstract: A waterproof foot covering has a breathable upper enclosure of an upper, a waterproof inner lining sleeve to line the upper enclosure, and a waterproof lower enclosing shell of a lower. The bottom open end of the upper enclosure, the bottom open end of the inner lining sleeve and the upper open end of the lower enclosing shell are interconnected together by sewing, thereby forming a stitched seam. A waterproof seam-sealing member is disposed inwardly of the stitched seam. The seam-sealing member is attached to the inner surfaces of the inner lining sleeve and the lower enclosing shell, whereby water-permeation through the stitched seam from a location between the inner lining sleeve and the upper enclosure to the exterior of the upper enclosure is permitted while water-permeation through the stitched seam to the interior of the inner lining sleeve and the lower enclosing shell is prevented. A method for providing the seam sealing member to the stitched seam of the upper enclosure, the inner lining sleeve and the lower enclosing shell is also disclosed.

Patent CA-2260673-A1 (CA)
Inventor: LANGE MICHEL
IPC: A23C9/12
Filed: 1999-02-04
Abstract: This invention relates to a process for producing a lactose-free milk which does not confer a sweet taste to the milk normally resulting from the hydrolysis of lactose into monosaccharides. The process comprises the step of reducing the lactose content of the milk to about 3% prior to hydrolysis with lactase. When the milk is skimmed milk, the protein content may be increased to about 3.8-4.0% or greater, which further improves the organoleptic properties of the milk. Milk so processed and dairy products derived therefrom are also disclosed and claimed.

Patent CA-2267507-A1 (CA)
Inventor: ARNTJEN GERD
IPC: F24F11/02
Filed: 1999-03-30
Abstract: The invention relates to a ventilation apparatus for arranging in a wall-surface region of a building. Such ventilation apparatuses are customary for so-called unheated sheds (stables, cowsheds, pigsties, etc.). In this case, an outer side of a shed building is closed against the entry of wind only with one or more tarpaulin-like wall elements, which are arranged one above the other and can be opened for more extensive ventilation of the shed by virtue of the fact that the wall element is wound toward the top like a roller blind. The object of the invention is therefore to provide a ventilation apparatus in which the wall element is opened by defined or controlled lowering of the top margin of the wall element while simultaneously winding the wall element and only by means of a single drive. This object is achieved according to the invention in that the wall element and the tension element together with further elements form a bow, ultimately more or less closed via the single common drive member, in which case the tension member itself is preferably unwound on the winding shaft to the same extent as the wall element is wound, or vice versa, specifically in opposite directions to one another.

Patent CA-2281127-A1 (CA)
Title: Light flashing apparatus
Inventor: PIETRINFERNO UMBERTO
IPC: H05B37/02
Filed: 1999-08-18
Abstract: The light flashing apparatus of the present invention is a four-button control switch in conjunction with an electronic circuit which is installed within an existing light switch junction box and replaces conventional switches. In addition to the two conventional on and off modes of a light switch, the apparatus allows for two different flashing modes; slow and fast flashing of the same light. The selection of any of the four modes overwrites the previous mode of operation, thereby having only one operating mode at a time. Any operating mode is selected by pushing a corresponding one of the four buttons. The slow flashing mode is used, for example, to help someone find your address when there is no hurry (taxi, delivery and so on) while the fast flashing mode corresponds to an emergency situation. The fast flash mode may also be remotely activated by a radio frequency RF signal transmitter. The apparatus of the present invention also does not require any other external source of energy to be functional, other than the existing wiring system.

Patent CA-2288976-A1 (CA)
Inventor: TOBIN ELAINE
IPC: C12N5/10
Filed: 1998-04-17
Abstract: La présente invention implique l'isolation et la caractérisation du premier facteur de transcription du phytochrome découvert, sur lequel les phytochromes ont une action de régulation, ce facteur étant une protéine appelée CCA1 qui se lie au site promoteur du gène protéinique de fixation de la chlorophylle Lhcb1*3 de l'Arabidopsis. On sait que le gène Lhcb1*3 de l'Arabidopsis est régulé par les phytochromes dans les jeunes plants étiolés sur lesquels une brève exposition à une lumière rouge fait considérablement augmenter le taux de l'ARNm dans ce gène. Une activité de liaison d'ADN, appelée CA-1, interagissant avec le site promoteur de Lhcb1*3 a déjà été découverte dans des extraits cellulaires. Cette activité de liaison a été utilisée pour obtenir un clone d'ADNc pour un facteur de transcription se liant spécifiquement au promoteur de Lhcb1*3. L'utilisation des techniques du génie génétique pour modifier l'expression de CCA1 a donné des changements inattendus dans le rythme de floraison de la plante. Lorsque CCA1 est surexprimée, il apparaît que les rythmes circadiens normaux de la plante se perturbent. Les plantes fleurissent après un temps beaucoup plus important même en présence de photopériode, condition qui, normalement, favorise la floraison. On obtient ainsi un procédé permettant de prolonger la croissance végétative et retarder la floraison.

Title: Cytokine-, stress-, and oncoprotein-activated human protein kinase kinases
Inventor: DAVIS ROGER J
IPC: A61K48/00
Filed: 1998-07-07
Abstract: Disclosed are human mitogen-activated (MAP) kinase kinase isoforms (MKKs). MKKs mediate unique signal transduction pathways that activate human MAP  kinases p38 and JNK, which result in activation of other factors, including activating transcription factor-2 (ATF2) and c-Jun. The pathways are activated by a number of factors, including cytokines and environmental stress. Methods are provided for identifying reagents that modulate MKK function or activity and for the use of such reagents in the treatment of MKK-mediated disorders.

Patent CA-2304557-A1 (CA)
Title: Polyamine transport inhibitors
Inventor: AUDETTE MARIE
IPC: C07C211/14
Filed: 1998-04-21
Abstract: The present invention describes the design, synthesis and therapeutic use of a variety of novel inhibitors of polyamine transport. The main feature of this class of transport inhibitors is to incorporate a linker or side chain that prevents the uptake of polyamines and helps to conjugate polyamine analogs to form dimers with high inhibitory potency against polyamine uptake. These new compounds incorporate features that are designed to maximize their chemical and metabolic stability and their ability to bind to the polyamine transporter, and to minimize their toxicity by preventing their absorption by the cells. The purpose of such inhibitors is to prevent the uptake or salvaging of circulating polyamines by rapidly proliferating cells such as tumor cells, in order to potentiate the effect of therapeutic inhibitors of polyamine biosynthesis such as alpha-difluoromethylomithene.
