Abstract: A portable drive carrier (1) is described for a memory device for use at a computer or workstation. The carrier (1) has a rotatable handle (8) that is adapted to assist in the detachment and ejection of the carrier (1) from a Ushaped receiving frame (2) that is commonly mounted at an existing drive bay of the computer or workstation. The carrier (1) includes a pair of handle cams (25) that are coupled to respective sides of the carrier (1) so as to move along the sides in response to a rotation of the handle (8). The handle cams (25) move into engagement with and apply a pushing force against the receiving frame (2) whereby the carrier is advanced relative to and detached from the receiving frame to enable the carrier to be pulled out of and removed from the frame. The handle cams (25) are interfaced with force transmitting surfaces (44) formed in the handle (8) so that a rotation of the handle is transferred to the handle cams to cause the handle cams to move along the sides of the carrier (1) in order to apply the pushing force against the receiving frame (2).

Title: Apparatus and method for winding paper
Inventor: SVANQVIST TORD OLOF SIXTEN
IPC: B65H18/08
Filed: 1998-06-17
Abstract: An apparatus and method for winding tissue webs into a parent roll (25) is disclosed and includes a rotatable reel drum (19) having a flexible outer shell (23) for engaging a web (15) of tissue paper against a reel spool (26).  A deflection sensor (35) is mounted adjacent to the inner surface of the outer shell (23) for measuring the amount of deflection of the flexible outer shell (23) caused by the paper roll. The amount of deflection is related to the pressure at the nip point and, by moving the reel spool (26) and flexible reel drum (19) away from each other as the diameter of the paper roll increases, the pressure can be controlled at a desired level. Accordingly, a predetermined light nip pressure can be applied to the roll as the tissue web is wound thereon and large parent rolls (25) of high bulk tissue can be manufactured with desired properties when unwound.

Patent CA-2301116-A1 (CA)
Title: Method of and apparatus for manufacturing an optical fiber preform
Inventor: GARNHAM CHERYL JANE
IPC: C03B37/012
Filed: 1998-08-19
Abstract: Optical fibers are produced by means of a direct sleeving technique that allows the collapsing of the outer jacket tube onto the inner core rod to be achieved directly during the drawing phase of optical fiber manufacture. In the course of the optical fiber manufacturing process, a preform having an enclosed annular gap/cavity is produced. The preform is produced by first aligning a rod within a sleeve tube using a centering device which also creates an air-tight seal. A vacuum may be maintained in the annular gap/cavity of this assembly. A heat source is then applied in order to collapse the extreme ends of said tube onto the respective extreme ends of the rod, the traverse speed of said heat source moving from one end to the other being controlled so to avoid any cracking in the final preform. The obtained preform is then mounted onto a drawing tower where the fiber is drawn while simultaneously collapsing the remaining portion of the tube onto the rod. A device for aligning a rod within a tube, such as used in the preform manufacturing process, is also disclosed and comprises a threated body and rings, o-rings and splitrings.
Patent CA-2302392-A1 (CA)
Title: Compositions and methods for contraception in or sterilization of mammals
Inventor: ENRIGHT FREDERICK
IPC: C07K19/00
Filed: 1998-09-01
Abstract: Amphipathic lytic peptides are ideally suited to use in a ligand/cytotoxin combination to induce sterility or long-term contraception in mammals. The peptides act directly on cell membranes, and need not be internalized.  Administering a combination of gonadotropin-releasing hormone (GnRH) (or a GnRH agonist) and a membrane-active lytic peptide produces long-term contraception or sterilization in mammals in vivo. The compounds are relatively small, and are not antigenic. Lysis of gonadotropes has been observed to be very rapid (on the order of ten minutes). The two components --the ligand and the lytic peptide -- may optionally be administered as a fusion peptide, or they may be administered separately, with the ligand administered slightly before the lytic peptide, to activate cells with receptors for the ligand, and thereby make those cells susceptible to lysis by the lytic peptide.

Abstract: Hémodialyseur (10) à fibres creuses qui est fabriqué selon un procédé d'encapsulation pour obstruer préalablement de manière étanche les extrémités (17) des faisceaux (14) de fibres creuses avant le processus d'encastrement. De la matière (21) à durcissement rapide partiellement durcie est placée dans les bouchons terminaux (18, 19) ou bouchons d'encastrement de l'enveloppe (11) de l'hémodialyseur. Les bouchons (18, 19) sont ensuite placés sur les extrémité ouvertes (12, 13) de l'enveloppe (11) d'hémodialyseur de manière que les extrémités (17) des faisceaux (14) de fibres s'étendent dans la matière (21) partiellement durcie, ce qui provoque l'encapsulation des extrémités (17) des faisceaux (14) de fibres dans la matière partiellement durcie. Une fois ladite matière durcie, ledit hémodialyseur (10) est encastré à l'aide de moyens classiques. Ledit procédé d'encapsulation permet le maintien des propriétés bouffantes du faisceau, ce qui facilite l'encastrement ultérieur et évite l'effet de mèche des fibres creuses à flux élevé.
