IPC: B29K105/02
Filed: 1992-01-07
Abstract: A wraparound heat shrinkable sheet for covering pipes or cables is positioned therearound so its longitudinal edges overlap. A  first patch is then positioned over the lapped edges, and a second patch, which is wider than the first patch, positioned over the first patch and secured to the underlying wrapped sheet. Heat is then applied, preferably by hot mastic. The heat acts to shrink the sheet which tensions the second patch, thereby directing a radial force downward onto the first patch.

Patent CA-2102883-A1 (CA)
Inventor: ARENDT JAMES W
IPC: G06F12/10
Filed: 1993-11-10
Abstract: Abstract of the Disclosure System and Method for Lazy Loading of Shared Libraries Lazy loading of executable library objects reduces operating system  overhead  and  memory  commitment  requirements  by postponing  object  loading  until  object  references  are expected.    Initial  task loading allocates only the main executable and library objects referenced by that executable. Secondary  referenced  objects  are  not  allocated.  Object references cause page faults for allocated but not loaded pages.  Page  fault handling  causes  loading  and  fixup  of executable objects. Page fault handling also determines the next level of object references and allocates memory for the next object level. Shared memory systems allow sharing of executable objects until  explicitly referenced.  Once referenced,  memory fault causes copying and fixup to referencing task memory area.

Abstract: Désétaleur de signal pour système AMRC. L'appareil traite des échantillons du signal reçu au moyen de répliques filtrées des séquences de coefficients de codage associées aux utilisateurs du système. Les symboles transmis par chaque utilisateur du système sont récupérés au moyen d'une réplique filtrée de la séquence de coefficients de codage associée à cet utilisateur. Dans la version présentée, le canal de communication entre l'émetteur de chaque utilisateur et la station de base est à bande limitée. Par conséquent, à l'intérieur de l'émetteur de chaque utilisateur, un appareil de filtrage ayant une caractéristique de fréquence est utilisé pour limiter le spectre de fréquences de chaque signal codé à une bande passante prédéterminée égale ou inférieure à celle du canal de communication. Suivant la présente invention, chaque réplique filtrée reproduit cette caractéristique de fréquence. Le canal de communication a également une caractéristique de fréquence, que peut reproduire chaque réplique filtrée.
Patent CA-2116092-A1 (CA)
Title: Spool for life-line
Inventor: NOWLAN JEAN
IPC: B65H75/20
Filed: 1994-02-21
Abstract: This invention relates to a life-line spool. The life-line has always played an important role in life-saving. To manage large quantities of line during transport or during rescue work, a line reel, a line box or a line bag is used. I have found that a life-line spool is an alternative to the box, the bag or to the reel. With this spool, the life-line is easy to transport, easily uncoiled when pulled out on the rescue and can be just as easily coiled back on the spool during or after the rescue. The spool is made of one long bar with two smaller parallel bars fixed perpendicular to it so as to divide the long bar in three sections. The two parallel bars serve both as handles and as line support-bars. The center section of the long bar serve as the frame of the spool and the two end section serve as line retainer-bars to hold the line so the coils of line do not fall off the line support-bars. To coil the life-line, the line is tied to one of the support-bars; the spool is held by the end of the two support-bars which serve as handles; the life-line is coiled around the support-bars by executing a long circular movement of the spool from side to side and by catching the line with the retainer-bars which extend pass both handles. To carry the life-line, the spool is held with the line support-bars pointing up so the line does not fall off the spool. To unwind the life-line, the spool is held by the long frame-bar with the two parallel line support-bar pointing in the direction the line needs to be pulled out. When the line is pulled, it freely uncoils from the spool. To stop and to recoil the line, the spool is simply reversed and held by the two handles.

Title: System and method for laser welding an inner surface of a tubular member
Inventor: PIRL WILLIAM E
IPC: B23K26/08
Filed: 1994-09-12
Abstract: ABSTRACT OF THE DISCLOSURE System and method for laser welding an inner surface of a tubular member, which tubular member may be a repair sleeve disposed in a nuclear heat exchanger heat transfer tube.  The system includes a laser for generating high intensity laser light sufficient to fuse the sleeve to the inside diameter of the heat exchanger tube, the tube being  of  the  type  typically  found  in  nuclear  heat exchangers.  A fiber-optic cable is optically coupled to the laser for conducting the laser light therethrough.  The fiber-optic cable has a predetermined configuration to homogenize the laser light so that the laser light obtains the desired spatial coherency as the light is emitted from the fiber-optic cable.  A mirror is optically coupled to the fiber-optic cable so as to receive the homogenized light beam emitted from the fiber-optic cable.  The mirror is also optically coupled to the inner diameter of the sleeve for reflecting the homogenized light beam onto the inner diameter of the sleeve to weld or fuse the sleeve to of the tube.  In this manner, the sleeve is welded to the inside diameter of the tube to sleeve the tube.

Filed: 1995-05-26
Abstract: The control process according to the invention is usable with high performance production processes for producing printed products by collecting, inserting and/or collating, e.g. with the aid of a drum (10). It comprises recording an image of the products being formed following each addition of a further component with a camera (K), comparison of the recorded image with a corresponding, stored calibration image, and using the results of the comparison for generating control signals, e.g. for discharging faulty products or activating alarm means. Instead of stationary image recording means such as cameras, movable reading heads can be used in the inventive process also.
