Patent CA-2168949-A1 (CA)
Inventor: HARVEY ROBERT ALAN
IPC: B41J2/045
Filed: 1994-08-10
Abstract: As a step in the manufacture of an ink jet printer, a cover (16) is adhesively bonded to a piezoelectric layer (10) having parallel grooves (20) which will serve as ink channels in the finished printer. Mating surfaces are prepared, excess adhesive is applied and bond pressure exerted until surface extremities of the two surfaces come into contact, producing a bond layer of 2µm or less. To ensure that the flow distance of excess adhesive is uniform over the bond plane, grooves (32) are cut at the margin (30) of the piezoelectric layer.

Abstract: DNA sequences are described which on the codogenic strand code plant debranching enzymes, whose transcripts formed in transgenic plants code new proteins with the enzymatic activity of debranching enzymes which in transgenic plants reduce the degree of branching of amylopectin starch and DNA sequences which on the codogenic strand code plant debranching enzymes, whose transcripts formed in transgenic plants prevent the synthesis of proteins with the enzymatic activity of debranching enzymes, which in the transgenic plants increases the degree of branching of amylopectin starch, as well as plasmids on which these DNA sequences are localized, which can be introduced into plant cells and plants. Also described is a process for the production of plants changed by genetic engineering whose amylopectin starch is modified, and the modified starch obtainable from these plants.

Title: Multilayer preform used for plastic blow molding and method for making the preform
Inventor: SLAT WILLIAM A
IPC: B29C45/14
Filed: 1994-09-02
Abstract: A multilayer preform (26a, 26b, 26c) used for plastic blow molding and a method for making the preform provides an inner layer (28) of polyethylene naphthalate and an infection molded outer layer (30) of polyethylene terephthalate which has reduced transmission of gas upon blow molding as a container due to the gas barrier provided by the inner layer of polyethylene naphthalate. The inner layer (28) of polyethylene naphthalate by itself or along with a further inner layer (32) of virgin polyethylene terephthalate is thermoformed prior to the injection molding of the outer layer (30) of polyethylene terephthalate. A minimal amount of the polyethylene naphthalate which is relatively expensive can be utilized due to die thermoforming and injection molding as disclosed.

Title: Dishwasher with food particle macerator and mincer
Inventor: EDWARDS JAMES M
IPC: A47L15/42
Filed: 1996-04-23
Abstract: A dishwasher sump is divided into a collection chamber and a pump chamber by a filter.  Food particles collect in the collection chamber while filtered wash liquid collects in the pump chamber.  A pump has an inlet located in the pump chamber.  The filtered wash liquid is recycled and sprayed on objects in the dishwasher by the pump.  The impeller is driven by a shaft extending through the collection chamber and a wall separates the pump chamber from the collection chamber.  Food particles in the collection chamber are minced by a rotating blade on the pump shaft.  Balancing vanes on a rear face of the impeller prevent food particles and dirty water from flowing into the filtered liquid from the collection chamber.  At the end of a wash cycle, the minced food particles are pumped to a drain with the wash liquid.

Patent CA-2213482-A1 (CA)
Title: Fluorescent optical sensor
Inventor: COLVIN ARTHUR E JR
IPC: G01N21/77
Filed: 1996-02-15
Abstract: A fluorescent sensor (10) for detecting the presence and amount of an analyte. The fluorescent sensor (10) has a photodetector (12), a high pass filter (14) located adjacent the photodetector (12), and a glass layer (80) located adjacent the high pass filter (14). An indicator layer (18) is located adjacent the glass layer (80) and a light emitting diode (20) is embedded in the indicator layer. The indicator layer has indicator molecules that provide a fluorescent emission as a result of light from the light emitting diode (20). The indicator layer (18) also allows an analyte to diffuse into it and the presence of the analyte reduces the amount of light emitted from the indicator molecules that passes through the glass layer (80) and the high pass filter (14) and is incident upon the photodetector (12). Since the amount of current from the photodetector (12) depends upon the incident light, this is used to detect the presence and amount of analyte. In one embodiment a waveguide is also present.

Inventor: TREMBLAY JACQUES P
IPC: A61K35/34
Filed: 1996-03-15
Abstract: La présente invention concerne un procédé de traitement préalable de cultures de myoblaste de donneur sain. Ce procédé utilise des facteurs de croissance ou des facteurs trophiques, tels que le facteur de croissance de fibroblaste basique (bFGF), en cas de transplantation sur des sujets souffrant de dystrophie musculaire telle qu'une myopathie. Grâce à ce procédé, les muscles du receveur renferment une proportion plus élevée de cellules fonctionnelles, ce qui est attesté par une incidence plus importante des fibres dystrophino-positives, de sorte qu'il n'est pas nécessaire de préconditionner les muscles du receveur par irradiation ou administration de toxines. Des myoblastes de donneurs murins exprimant le gène marqueur  beta -galactosidase ont été cultivés dans un milieu contenant du bFGF à raison de 100 ng/ml, pendant au moins les deux derniers jours précédant leur injection dans les muscles jambiers antérieurs (TA) gauches de souris receveuses, compatibles CMH, en l'occurrence des "mdx" ou "modèles animaux de la myopathie de Duchenne". Des myoblastes des mêmes cultures primaires ont été également cultivés sans bFGF et injectés en témoin dans les muscles jambiers antérieurs (TA) droits. Les souris receveuses ont subi un traitement immunodépresseur à base de FK 506. Vingt-huit jours après transplantation myoblastique, la proportion de fibres positives par rapport à la  beta -galactosidase était considérablement supérieure (plus que quadruplée) après culture en milieu bFGF qu'après culture en milieu sans bFGF. Les fibres positives par rapport à la  beta -galactosidase étaient également, dans leur quasi-totalité, dystrophino-positives.
