Patent CA-2192285-A1 (CA)
Inventor: ZIERPKA KATRIN
IPC: B23B51/00
Filed: 1996-12-06
Abstract: Screwholes must usually be pre-drilled. Power drills are used if the pre-drilling is to be performed mechanically. The screws themselves are usually screwed into place using power screwdrivers. There is now a new drill bit that is also intended to be used in conjunction with these conventional power screwdrivers.   The drill bit (1) comprises a drilling section (4) and a shaft section (3) having an hexagonal cross section for connecting the bit in a torsionally rigid manner with a conventional power screwdriver. As a result, it is no longer necessary to use different power tools for the different operations of drilling holes and driving screws.       The invention is intended for use by the home handyman and professional workman.

Patent CA-2193628-A1 (CA)
Inventor: HERNANDEZ WALTER
IPC: G01H9/00
Filed: 1995-08-04
Abstract: L'invention porte sur un procédé et un système permettant d'analyser avec précision les signaux des codeurs de machines tournantes et réduisant le bruit et les autres interférences présents dans les signaux de codage à l'aide de nouveaux moyens d'extraction d'informations utiles d'une puissance sans précédent. La distorsion des signaux résultant des fluctuations du régime de la machine et des "fuites" relatives aux transformées rapides de Fourier sont éliminées en recueillant les valeurs numériques des signaux de codage à des instants discrets fonction de la vitesse moyenne de rotation de l'arbre à raison d'un nombre entier constant d'entiers par tour. La modulation d'amplitude est éliminée par une combinaison spectrale adéquate des bandes latérales de droite et de gauche du signal principal de codage. Le bruit additionnel est éliminé en multipliant les bandes latérales et en moyennant les résultats de plusieurs enregistrements de données.

Abstract: L'invention concerne une enveloppe tubulaire (10) conçue pour être placée autour d'une denrée alimentaire (en particulier un produit à base de viande) avant la cuisson ou la salaison. Cette enveloppe présente un aspect pratiquement transparent lorsque la denrée alimentaire est placée à l'intérieur. Elle comprend une partie tubulaire à mailles (11) réalisée en longueur continue à partir de fil transparent, la paroi de cette partie tubulaire à mailles (11) présentant un motif à mailles de type boucles extensibles permettant d'obtenir une surface ouverte supérieure à 50 % lorsque les boucles sont entièrement étirées. Cette paroi est cependant pratiquement imperméable à la denrée alimentaire. Cette enveloppe comprend également des fils élastiques (12) de renforcement circonférentiels fixés de façon espacée le long de la partie tubulaire à mailles. Ces fils se tendent tandis que la partie tubulaire à mailles reste extensible au moment où la denrée alimentaire y est introduite, de sorte que ces fils élastiques de renforcement circonférentiels (12) exercent une pression dans la surface de la denrée alimentaire. Ceci permet d'obtenir un motif superficiel distinctif, la denrée alimentaire dépassant à l'intérieur de bandes (14) situées entre les délimitations circonférentielles.

Abstract: An  inertial  sensor  unit  for  determining  north,  has  a housing and a positioning gimbal rotatably mounted in this housing about a substantially vertical axis. A releasable, cooperating detent mechanism defines  three  fixed angular detent  positions  of  the  positioning  gimbal  about  the substantially vertical axis relative to the housing.  The positioning gimbal is successively rotated into the three detent positions. A fiber optical gyro is mounted on the positioning gimbal.  The  input axis forms an acute angle with  a  substantially  horizontal  axis  orthogonal  to  the above  mentioned  substantially  vertical  axis.  A  signal processing  system  is  provided,  to  which  the  signals generated by the fiber optical gyro in the three detent positions  are  applied.   The  signal  processing  system provides,   therefrom,   the  angle  between  a  reference direction and north.

Title: Poppet damper in exhaust gas duct
Inventor: YAMAZAKI SATOSHI
IPC: F23L13/00
Filed: 1995-09-25
Abstract: One end of a passenger bridge (1) or a goods-handling device of mobile type can be expediently and securely connected to a door (20) on a craft (21), especially an aircraft, by determining the position of the door in relation to a reference point on the craft and storing it in a computer system.  Furthermore, the absolute position of the door when the craft has come to a halt and the passenger bridge or the goods-handling device is to be connected, is determined by measuring the distance from a reference point (18) on the ground to the craft. Finally, the computer system (7, 16) guides the passenger bridge to the door of the craft, the position of the end of the passenger bridge or the goods-handling device being determined during the guiding operation and inputted into the computer system. To further shorten the connection time, the passenger bridge or the goods-handling device is advantageously guided to an initial position of connection in the vicinity of the craft, in which position the end of the passenger bridge or the goods-handling device is aligned with the expected position of the door and disposed at a small distance therefrom, before the craft has come to a halt.

Patent CA-2205662-A1 (CA)
Title: Method and apparatus for coating strip article up to strip edge
Inventor: SMITH GARY J
IPC: B05C9/04
Filed: 1995-11-23
Abstract: Apparatus for coating a strip article comprises a coating head having a coating surface and elongated open-sided slot formed in the coating surface communicating with an interior channel for delivery of coating material to said slot for transfer to a strip article to be coated. The slot has a slot extension extending into the coating surface at at least one longitudinal end of the slot for applying coating material to an edge region of the strip article. The slot extension communicates with the interior channel only through a constricted opening that prevents substantial leakage of coating material from the slot extension when the slot extension becomes uncovered by the edge region of the strip article. In this way, the strip article can be coated completely up to its transverse edges, without risk of substantial spillage of coating material if the ends of the coating slot become uncovered by the strip article due to inaccurate tracking or variable strip width.

Title: Bulk cryopreservation of biological materials and uses for cryopreserved and encapsulated biological materials
Inventor: RAJOTTE RAY V
IPC: A01N1/02
Filed: 1996-01-16
Abstract: A method for bulk cryopreservation of biological material includes the steps of providing a flexible container, such as a freezer bag, containing biological material that is treated with cryoprotectant and freezing the biological material to below -100 .degree.C and preferably below -196 .degree.C for deep freeze long-term storage. In the preferred embodiment, the bag is placed in a holder that maintains the cross-sectional area of the bag essentially constant and small enough (e.g, about 5mm width) to facilitate uniform heat transfer to and from all regions of the bag. This facilitates uniform nucleation of the biological material after supercooling which enables controlled and uniform slow cooling through from about -7.5 .degree.C to a temperature in the range of about -40 .degree.C to -80 .degree.C, thereby maintaining the viability of the cells. The present invention also provides for encapsulation of the biological material before cryopreserving, whereby the material is encapsulated in a gel, such as alginate. Further provided are methods for stabilizing the material for shipment, storage in culture, and transplantation through the use of encapsulation. Encapsulation of the material also improves or help retain its viability over unencapsulated material.

Abstract: A truck deck with ground level loading/unloading position includes guide tracks supported by a support frame. Guide members consisting of pivotally connected sections are telescopically received in the guide tracks. A load platform is supported by and slidably movable in relation to the support frame. A first pair of chains pull the load platform and extend the guide members. When the guide members reach a fully extended position with the majority of the weight of the load platform past the pivot axis, they pivot and thereby guide the movement of the load platform in a downwardly direction onto a ground surface. A second pair of chains lift the load platform from the ground surface and move it along guide members until the guide members pivot to a substantially horizontal position. The second pair of chains then pull the load platform and the guide members back into a retracted position.
