Patent CA-2222617-A1 (CA)
Title: System for controlling the energy delivered to a patient for ablation
Inventor: SHERMAN MARSHALL L
IPC: A61B18/04
Filed: 1996-05-01
Abstract: This invention is a power control system and method that controls a power generator (50) to vary the duty cycle of a power output provided to a delivery instrument (10) for delivering that power to a site in a patient for ablation.  The peak power can be raised and the duty cycle lowered to result in deeper lesions. A power output having a higher peak power for producing deeper lesions can be obtained by using a lower duty cycle having a longer "off"  period in order to deliver more power to the ablation site without overheating the delivery instrument (10). The temperature of the delivery instrument is monitored, and the duty cycle is lowered when the temperature exceeds a predetermined maximum limit. After the instrument has cooled sufficiently, the duty cycle is then increased to its previous level.

Title: Universal spacer/energy transfer dyes
Inventor: GLAZER ALEXANDER N
IPC: C12Q1/68
Filed: 1996-08-12
Abstract: Fluorescent labels are provided employing energy absorber/donor components and energy acceptor/fluorescer components joined together by a spacer which comprises sugar phosphate monomeric units, particularly ribosyl phosphate monomeric units, where the sugar groups are free of active hydroxyl groups. Particularly, an energy transfer component is substituted at the 5' position of the spacer chain, while the other energy transfer component is substituted at the 1' position of the 3' terminal ribosyl group of the label forming an ET cassette for linking to a nucleic acid sequence with any compositions.  By employing combinations of ET components, with a common energy absorber/donor and different fluorescers, one can provide for families of labels which can be tagged to any target molecules and which can be excited at a single wavelength and fluoresce at different wavelength with large Stokes shifts. The compositions find particular application in sequencing.

Title: Method and apparatus for handling logs of convolutely wound webs
Inventor: VIGNEAU RICHARD J
IPC: B65H19/29
Filed: 1998-03-16
Abstract: A method and apparatus for handling logs of convolutely wound webs which includes providing a rewinder-tail sealer wherein a glue stripe is applied to a predetermined circumferential location on a partially unwound log and the log rewound by rolling on itself toward and into a pair of spaced-apart rollers, providing a path from the roller pair to log receiver wherein logs sequentially roll in the path, the path having fixed dimensions, operating the rewinder-tail sealer to develop logs of a first nominal diameter to enable the roller pair to controllably rotate each log for positioning the glue stripe at a first angular orientation, which in combination with the fixed dimensioned path enables each log to be received in the receiver with its glue stripe in a second angular orientation, changing the operation of the rewinder to develop logs of a second nominal diameter, and by correlating the second nominal diameter with the fixed dimensioned path to enable each second nominal diameter log to be received in said receiver with its glue stripe in the second angular orientation and adjusting the spacing between the roller pair to be slightly less than the second nominal diameter.
Patent CA-2232770-A1 (CA)
Inventor: SHELINE CHERYL A
IPC: B60R13/06
Filed: 1998-03-20
Abstract: An improved tool for, and a method of, crimping weatherstrips in an essentially continuous motion along the in-place weatherstrip, e.g. about a door flange or the like. the head is provided with a handle extending from the top therefrom at a convenient angle to allow an operator to assume a position alongside the door flange.  The handle, or at least the grip thereof, is capable of swiveling about the longitudinal axis of the handle, to reduce stress on the hands, wrists, and arms of an operator by permitting guiding motion of the tool ahead around the door flange while minimizing the amount of turning of arms or hands, or repositioning of the operator's body, as the tool is caused to progress entirely along the length of the weatherstrip. This length is often the entire perimeter of the door opening.  In using this improved tool to perform the crimping operation, the operator can move his/her arm in a generally circular motion, causing the tool head to follow the door opening flange, while the swivel handle accommodates the changes in angle as this motion proceeds. Another feature of the invention is the provision of a spring-loaded crimping roller pivotally mounted on the tool head, in opposition to a fixed crimping roller.  Preferably, both crimping rollers are power driven.  This allows the axes of the crimping rollers, and the spacing between them, to vary as the tool progresses in its action, so as to accommodate changes in thickness of the door opening flange.
