Abstract: On décrit un procédé d'expression d'un gène hétérologue dans la glande mammaire d'un mammifère ruminant. L'invention est utile pour produire une ou des protéines hétérologues dans le lait du mammifère, pour produire une ou des enzymes hétérologues qui sont fixées à la membrane des cellules épithéliales de la mamelle et qui peuvent agir sur un composant du lait du mammifère, ou pour produire un ou des oligonucléotides ou des ribozymes antisens inhibant l'expression d'un gène dans les cellules épithéliales de la mamelle. Le procédé fait appel à une perfusion d'un complexe liquide comprenant un produit de recombinaison génétique, dans l'arbre des canaux galactophores du mammifère. Le complexe liquide peut être injecté avant que le mammifère n'atteigne la maturité sexuelle et après qu'il a développé les canaux des trayons fonctionnels. On peut également injecter un complexe liquide exempt de rétrovirus vivants. Lorsque cela est souhaité, le produit de recombinaison génétique injecté peut être traité avec un composé polycationique et/ou un lipide pour améliorer l'efficacité avec laquelle il est absorbé par les cellules épithéliales de la glande mammaire.

Title: Screw driving method and screw driving apparatus
Inventor: ARATA KEN
IPC: B25B21/02
Filed: 1997-02-07
Abstract: When a screw 14 is driven into workpieces 61 and 62, it is possible to reduce any reaction that a driver bit 11 is raised so as to obtain fast and reliable screw driving. In the screw driving method of the present invention, the screw is advanced with a strong pressing force of 7-10 Kg during a period from disengagement step of the screw from a carrier strip 14 to driving step of the tip of the screw to the predetermined depth (the lower surface) of the workpiece 61. When the screw is screwed into the workpiece 62, the driver bit 11 is advanced with a weak pressing force of 2-3 Kg. In a screw driving apparatus of the present invention, the fitted screw is disengaged from a screw carrier strip by means of a forward stroke force of the driver bit. The tip of the screw is driven to a predetermined depth in a workpiece. During the term between the disengagement and the driving of the screw, the driver bit is advised with a strong pressing force by a primary piston 26. Then, the screw is screwed into the workpiece 62 by advancing the driver bit 11 with a weak pressing force by a secondary piston 27 which passing through the center of the primary piston 26. The driver bit 11 is rotated by an air motor 31.

IPC: B25J3/04
Filed: 1998-03-26
Abstract: A pneumatic human power amplifier module is usable in conjunction with a wide variety of pneumatic actuators and lifting devices to provide a human power amplifier for lifting a load.  The module includes an end-effector, an electronic controller and a pneumatic circuit.  The end-effector contains a human interface subsection which is grasped by a human operator and a load interface subsection which engages the load to be lifted.  A force sensor in the end-effector detects the force imposed by the operator on the end-effector and transmits a signal representing the magnitude of the force to the controller.  The controller in turn sends a command to the pneumatic circuit, which controls the flow of air into the associated pneumatic actuator. The actuator drives the lifting device.  The controller and the pneumatic circuit are arranged such that the lifting device and the operator share the burden of lifting the load, with the operator supplying a predetermined percentage of the total force required to lift the load regardless of the size of the load.

Patent CA-2238026-A1 (CA)
Inventor: SMITH WILLIAM PAUL
IPC: G10L/
Filed: 1996-11-21
Abstract: A subband audio coder (12) employs perfect/non-perfect reconstruction filters (34), predictive/non-predictive subband encoding (72), transient analysis (106), and psycho-acoustic/minimum mean-square-error (mmse) bit allocation (30) over time, frequency and the multiple audio channels to encode/decode a data stream to generate high fidelity reconstructed audio. The audio coder windows (64) the multi-channel audio signal such that the frame size, i.e., number of bytes, is constrained to lie in a desired range, and formats the encoded data so that the individual subframes can be played back as they are received thereby reducing latency. Furthermore, the audio coder processes the baseband portion (0-24kHz) of the audio bandwidth for sampling frequencies of 48kHz and higher with the same encoding/decoding algorithm so that audio coder architecture is future compatible.
Patent CA-2245146-A1 (CA)
Title: Small particle size polyester/acrylic hybrid latexes
Inventor: SHIELDS GLEN DENNIS
IPC: C08F257/02
Filed: 1997-01-31
Abstract: This invention provides the preparation of water-dispersible polyester/acrylic hybrids via a two-stage emulsion polymerization process. For example, methacrylic acid and/or 2-hydroxyethyl methacrylate are copolymerized with styrene/acrylic monomers to yield a relatively hydrophilic and hydro-plasticized first stage. Subsequent additions of hydrophobic monomers to this first stage "seed" result in an inversion of the latex such that the more hydrophilic first stage is at the particle surface. This results not only in improved stability of the resulting latex without the use of additional surfactants, as evidenced by the production of reduced amounts of coagulum, while it also offers relatively low minimum filming temperatures due to the hydroplasticization of the shell of the particle. Furthermore, the use of the water-dispersible polyester results in extremely fine latex particle sizes which can significantly enhance coating properties such as film gloss and clarity.

Patent CA-2246071-A1 (CA)
Title: Extensible absorbent article including a release agent
Inventor: BURGHARDT DALE ALAN
IPC: A61F13/15
Filed: 1998-10-02
Abstract: An absorbent article includes an absorbent pad and an outer cover.  A release agent is applied to one of the outer surface of the absorbent pad and the inner surface of the outer cover.  The release agent prevents at least a portion of the outer cover from adhering to the absorbent pad.  In embodiments where the outer cover is extensible in a cross-direction and/or a longitudinal direction, the release agent prevents the absorbent pad from resisting mobility of the outer cover.  Thus the absorbent pad has substantially no adhesion to the outer cover where the release agent is applied.  Therefore, tearing of the absorbent pad anddamage to, or release, of superabsorbent material from the absorbent pad during extension of the outer cover, is prevented.  The release agent can be a silicon-active agent or a powder material having properties that prevent adhesion between adhesive and a forming tissue of the absorbent pad, or the outer cover.
