Title: Winder with elevated spool support rail
Inventor: BAGNATO LUIGI J
IPC: B65H19/30
Filed: 1995-08-11
Abstract: A winder in a papermaking machine has a frame (40) with horizontal rails (42) which are positioned above the apex of the surface of a rotatable reel support drum (34), which is fixedly mounted. As a relatively large diameter wound paper web reel, or jumbo, is formed on a spool riding on the rails, the surface of the jumbo remains tangent to the top of the support drum as the spool moves from a position vertically over the reel drum to a position laterally displaced horizontally along the rail. Centerwind drivel(s) (36, 38) control spool torque.      As the jumbo increases in size, it is moved linearly away from the initial position, while maintaining the paper web reel rotatively supported and in a nipping engagement with the support drum. Nip pressure between the support drum and the jumbo is controlled by the force of gravity and the horizontal positioning of the jumbo along the rails. The positioning of the jumbo along the rail may be controlled by a conventional pneumatic or hydraulic cylinder, or a screw mechanism. An alternative embodiment winder utilizes primary (121) and secondary arms (123) to position the jumbo and its spool along the reel rails.

Title: Enrichment of hematopoietic stem cells from blood or bone marrow
Inventor: SLAPER-CORTENBACH CLASINA MARI
IPC: C12N5/0789
Filed: 1996-01-17
Abstract: Process for enrichment of hematopoietic stem cells in a stem cell preparation e.g. bone marrow, umbilical cord blood and peripheral blood stem cell preparation. Non-stem cells, in particular monocytes and myeloid cells, are depleted from the preparation by adherence to an opsonized material, e.g. a scrubbed nylon fiber coated with human IgG and blocked with human serum albumin. Platelets are depleted from the stem cell preparation before contacting the opsonized material, e.g. by counterflow centrifugal elutriation. Alternatively, adherence of platelets to stem cells is prevented by the addition of a chelating substance to the medium in which the enrichment process is performed.

Abstract: A messaging system has a memory device, an external interface, and a controller coupled to the memory device and the external interface. If the controller receives a message from a calling party for a called party through the external interface, and the called party does not have a mailbox, then the controller creates a called party mailbox and stores the message in the called party mailbox. After saving the message in the called party mailbox, the controller alerts the called party of the existence of a message saved in the called party mailbox. The called party may call the messaging system to retrieve a message stored in the called party mailbox and may also send a reply message to the calling party. A mailbox will also be created for calling parties who wish to send store and forward messages to called parties. The messaging system provides calling parties with the ability to send or leave a message for any called party irrespective of whether the called party is a customer of the messaging service. The dynamic creation of mailboxes described maximizes the size of the messaging community, minimizes the investment required, and avoids unnecessary degradation to system performance.

Patent CA-2222417-A1 (CA)
Inventor: KIELY DONALD
IPC: C07C59/265
Filed: 1996-05-31
Abstract: Les rapides élévations de température caractéristiques des réactions d'oxydation hydrate de carbone-acide nitrique utilisées pour former des acides dérivés d'hydrate de carbone peuvent être modérées et la régulation de la température peut être facilement maintenue en insufflant un gaz tel qu'air, oxygène, azote ou autre dans le mélange réactionnel autant que nécessaire pour réguler la température de réaction. Ces conditions de réaction plus modérées permettent de produire une quantité accrue du produit souhaité et de réduire de façon concomitante des sous-produits qui peuvent être difficiles à éliminer et sont également souvent indésirables. Une fois achevé, le mélange d'oxydation est rendu basique (par exemple à l'aide d'un hydroxyde ou d'un carbonate de métal alcalin formant base, d'ammoniac ou d'une amine) jusqu'à présenter un pH auquel le ou les groupes carboxyle du produit constitué par l'acide dérivé d'hydrate de carbone sont entièrement sous forme de sels. La solution aqueuse est alors passée par une colonne de résine retardatrice d'ions pour récupérer le sel dérivé d'hydrate de carbone en se servant d'eau comme éluant. Si on le souhaite, le sel de l'acide dérivé d'hydrate de carbone peut ensuite être facilement récupéré en éliminant l'eau ayant servi de solvant ou par précipitation, par addition d'un composé organique miscible à l'eau tel que méthanol, éthanol, acétone, isopropanol, etc.

Title: Powered reciprocating saw and clamping mechanism
Inventor: WREN PHILIP
IPC: B23D51/04
Filed: 1998-01-23
Abstract: The invention relates to a powered reciprocating saw, in particular to a pruning saw. To simplify use of the saw a clamping mechanism is provided which holds an object in position while it is sawn. The clamping mechanism is mounted at the front portion 4 of the housing of the saw near the saw blade 20. The clamping mechanism comprises: a slide element 30 for sliding movement in cutting direction C of the saw blade, a supporting member 30; and a clamping arm 40 being rotatably mounted on the slide element 30, by means of a one way rotary clutch 42 such that the arm can freely rotate in one direction only, in which direction the clamping arm 40 moves towards the support member 30 to clamp an object therebetween in a clamping position below the saw blade for sawing it. When the saw is in use, it vibrates due to its reciprocating parts. Since the clamping arm 40 has a moment of inertia with respect to this axis of rotation of the one way rotary clutch 42, the oscillating movement is transformed into a stepwise, progressive rotational movement of the clamping arm which thereby closes automatically to clamp an object to be sawn.
