Title: Mandrin comportant un mecanisme limiteur de couple et un plan incline pour serrage final
Inventor: HUFF ROBERT O
IPC: F16D7/04
Filed: 1996-02-08
Abstract: Un mandrin servant à supporter de façon détachable un outil, tel qu'un foret, possède un accouplement limiteur de couple dans le mécanisme mis en rotation manuellement afin de fermer les mâchoires du mandrin sur l'outil. Quand le mandrin a été serré sur l'outil à un certain niveau de serrage, l'accouplement limiteur de couple se relâche. Ensuite, la rotation manuelle continue de l'élément constituant l'entrée de l'accouplement, exerce une action sur un mécanisme à came et à contre-came, ce qui provoque un serrage plus accentué des mâchoires du mandrin sur l'outil. Quand le mandrin est desserré afin de libérer l'outil, le mécanisme à came et à contre-came remet automatiquement le mandrin à son état initial, pour un nouveau serrage.

Title: Method of electrophotographically manufacturing a screen assembly
Inventor: GOROG ISTVAN
IPC: G03C5/00
Filed: 1995-08-03
Abstract: In accordance with the present invention, a method of electrophotographically manufacturing a luminescent screen assembly on an interior surface of a faceplate panel (12) of a color CRT (10) comprises the steps of coating the interior surface of the panel with a volatilizable, organic conductive material to form an organic conductive (OC) layer (32), and overcoating the OC layer with a volatilizable, photoconductive material to form an organic photoconductive (OPC) layer (34).  Then, a substantially uniform voltage is established on the OPC layer, and selected areas of the OPC layer are exposed to visible light to affect the voltage thereon, without affecting the voltage on the unexposed area of the OPC layer. Next, triboelectrically charged, light-absorbing screen structure material is deposited onto the unexposed area of the OPC layer to form a substantially continuous matrix (23) of light-absorbing material having open areas therein. The present method is an improvement over prior methods in that the present method includes the additional steps of forming a planarizing layer (35, 135) on the OPC layer, overcoating the planarizing layer with a second coating of the volatilizable, organic conductive material to form a second OC layer (132), and then overcoating the second OC layer with a second coating of the volatilizable, organic photoconductive material to form a second OPC layer (134). The phosphor materials are deposited onto a suitable charged and exposed second OPC layer so that the phosphors completely overlie the openings in the matrix and overlap at least a portion of the matrix adjacent to the openings.

Patent CA-2211473-A1 (CA)
Title: Hybrid screw
Inventor: MCDUFF PIERRE R
IPC: F16B25/02
Filed: 1997-07-24
Abstract: A hybrid screw comprises a flared head, a cylindrical stem and a distal pointed section with the flared head defining a cruciform opening adapted  to  be  engaged  by  a  rotatable  driving member, such as a manual or powered screwdriver. The cylindrical stem defines a longitudinal inner bore which communicates with the cruciform opening of  the  head  and with  the  inner  bore  defining longitudinal splines adapted to be tapped by a further  fastener,  such as  a conventional  solid screw.    A  side  opening  is  defined  in  the cylindrical stem to allow for material cut by the hybrid screw to evacuate through the inner bore. The  cylindrical  stem  and  the  distal  pointed section share a common thread comprised of first and  second  thread  sections  extending  helically around the cylindrical stem and the distal pointed section,  respectively.     Typically,  the  first thread section is large to firmly engage a friable material such as a gypsum wall, whereas the second thread section is adapted to cut through gypsum but also to engage a wooden component, such as two by four studs which can be typically found behind gypsum  sheets  in  the  construction  of  walls  in order to structurally secure the gypsum sheet in position.   Therefore,  the hybrid screw which is longer than the thickness of the gypsum sheet can be used even if it is driven at a location in the wall which is opposite a structural stud thereof as  the  second thread  section  will  be  able  to engage  the  wooden  member  without  reducing  the axial advancement per rotation of the screw and thus of the first thread section into the gypsum wall.    As  both  the  first  and  second  thread sections have a substantially same pitch, both the cylindrical stem and the distal pointed section will be firmly secured in the gypsum and in the wooden  member,  respectively.    Once  the  hybrid screw has been firmly installed in the wall,  it can receive a further fastener in its inner bore for mounting an object to the wall.

IPC: D21F3/02
Filed: 1997-07-25
Abstract: A pressing section of a papermaking machine is configured to increase pressed dryness significantly while maintaining substantial "one-sidedness", where both sides of the paper sheet have essentially identical surface characteristics. To strike a commercially useful balance between the application of high temperatures and pressures which increase paper dryness but can result in the production of two-sided paper and lowering nip pressure, which enhances one-sidedness but lowers effectiveness in removing water from the paper web, a press section according to the present invention has two conventional presses followed by two or three presses including one heated Extended Nip press. Preferably, smooth high temperature press felts are used to assist in the reduction of two-sidedness of the formed web. The dryer section may, alternatively, add a fifth press utilizing the first dry roll as the backing roll, two Extended Nip presses, a heated Extended Nip press followed by a heated conventional press, or a heated Extended Nip press in the third pressing section, followed by a conventional unheated press utilizing the first dryer as the backing roll.

Patent CA-2220905-A1 (CA)
Inventor: SHIBAHATA YASUJI
IPC: B60K23/04
Filed: 1997-11-12
Abstract: A yaw moment control system for a vehicle is provided to prevent the reduction of the turning performance during traveling of a vehicle at a low speed, which is designed, so that a driving force and a braking force are distributed to inner and outer wheels during turning of the vehicle in order to eliminate an over-steering tendency produced upon deceleration of the vehicle during turning thereof, thereby enhancing the stability during traveling of the vehicle at a high speed. A longitudinal acceleration Xg calculated in a longitudinal acceleration calculating circuit, a lateral acceleration Yg calculated in a lateral acceleration calculating circuit and a correcting factor Kv determined in a correcting factor determining circuit are multiplied by a control amount calculating circuit. Torque proportional to the resulting product is distributed to left and right wheels to eliminate the over-steering tendency produced upon deceleration of the vehicle during the turning thereof. When the vehicle is being decelerated and the vehicle speed V is smaller, the correcting factor Kv assumes a value smaller than 1.0, and at the other time, the correcting factor Kv assumes a value of 1Ø Therefore, when the vehicle is traveling at a low vehicle speed, an under-steering tendency can be prevented from being produced by the distribution of the torque, thereby preventing the reduction in turning performance.
