Title: Ligating clip having ramp-shaped vessel clamping members and tool for applying same
Inventor: PORTER WAYNE
IPC: A61B17/122
Filed: 1996-08-29
Abstract: A ligating clip having surfaces with slanted ramp members for clamping a tubular vessel. The ligating clip includes a pair of legs, each of which has a proximal end, a distal end and an inner surface. The proximal ends of the legs are joined to define a hinge. The legs may be forced together onto a tubular vessel  such  that  the  inner  surfaces  of  the  legs  are face-to-face in a closed position. A lock tab protrudes inward from the inner surface near the distal end of one of the legs. A lock slot is provided in the inner surface near the distal end of the other leg. The lock slot receives the lock tab to secure the ligating clip in the closed position.  A number of ramp members extend angularly inward from the inner surface of each leg in order to keep the tubular vessel from slipping in the distal direction as the ligating clip is closed. A tool for applying the ligating clip is provided with a cutting blade for severing the vessel after the ligating clip has been applied.

Title: Method and device for manufacturing biaxially oriented tubing from thermoplastic material
Inventor: PRENGER JAN HENDRIK
IPC: B29C48/90
Filed: 1995-03-17
Abstract: Method and device for manufacturing biaxially oriented tubing from thermoplastic material. The method comprises forcing the tube over a mandrel (6) at an orientation temperature of the plastic material, which mandrel comprises an expansion part (8) which produces expansion in the circumferential direction of the tube, and downstream of the mandrel the exertion of an axial pulling force on the tube, in the course of which the tube encounters a resistance which counteracts the movement of the tube over the mandrel. The method also comprises the exertion of an influence sector-wise in an adjustable manner in the circumferential direction of the tube on the resistance which counteracts the movement of the tube over the mandrel. In an advantageous embodiment the temperature of the plastic material of the tube is influenced sector-wise (20) in an adjustable manner, viewed in the circumferential direction of the tube. The measures according to the invention lead to better control over the manufacture of biaxially oriented tubing.

Patent CA-2193867-A1 (CA)
Inventor: BURTON SIMON C
IPC: C07K1/16
Filed: 1995-06-23
Abstract: Disclosed are resins, resin-protein/peptide complexes and methods for purifying proteins and peptides using said resins. The resins described herein are useful for the binding of a selected protein or peptide, particularly from an aqueous medium such as a fermentation broth, by hydrophobic interactions between the resin and the selected protein or peptide. The resin is characterized by the fact that it contains ionizable ligands and/or functionalities which are uncharged at the pH of binding the target protein or peptide, thereby facilitating hydrophobic interactions, and charged at the pH of desorption, thereby disrupting the established hydrophobic interaction between the resin and the target protein or peptide. More particularly, the present invention is directed to the use of the described resins in the purification of recombinant enzyme products such as proteases, for example, chymosin or subtilisin.

Title: Winding machine
Inventor: DOERFEL WALTER
IPC: B65H18/20
Filed: 1995-09-05
Abstract: The invention concerns a winding machine for winding up webs, possibly longitudinally divided webs, and preferably paper webs (PB). The winding machine comprises two support rollers (TW1 and TW2) which support, in a winding bed, the rolls (R; R'; R''; R'''; ...) to be produced and of which possibly one or both comprise casings (M1 and M2) which can be deformed, preferably to different degrees. During the winding process, the web (PB) running through the spacer gap (G) between the two support rollers (TW1 and TW2) partially wraps around one of the two support rollers (TW1). The winding machine further comprises a space (DR) delimited by the two support rollers (TW1 and TW2) and the partly formed roll (R; ...), as well as means for sealing this space (DR) at its ends (E) and from below the spacer gap (G) between the two support rollers (TW1 and TW2). Finally, the winding machine comprises means for generating an excess pressure in the space (DR) in order to balance the inherent weight of the roll (R; ...). Below the spacer gap (G) the sealing comprises a pivotable side wall (11) which extends substantially over the entire maximum web width of the roll (R; ...) to be produced and whose pivot axis (11A) extends approximately parallel to the support roller axes. The side wall (11) can be pivoted sealingly towards the support roller (TW1), around which the web (PB) is wrapped, whilst leaving free a web passage gap (GP) for the winding process. The side wall (11) can be moved, in particular pivoted, away from the support roller (TW1), around which the web is wrapped, for the introduction of the web (PB).

Title: Conductive probe for heating contact lens mold assemblies during demolding
Inventor: WIDMAN MICHAEL F
IPC: B29C39/36
Filed: 1997-06-02
Abstract: Demolding apparatus for reliably and repeatedly mechanically separating contact lens mold assemblies without damaging the contact lens formed therebetween. The mold assembly includes a frontcurve mold having a central mold section with a surrounding flange, and a corresponding backcurve mold also having a central mold section with a surrounding flange, with a contact lens being molded therebetween.      The demolding apparatus includes a conductive heating probe which contacts the backcurve mold of the lens mold assembly to conductively heat the backcurve mold.      Heat is conducted by the backcurve mold to cause a temperature gradient between the backcurve mold and the lens being demolded. The temperature gradient causes a differential expansion and shifting of the surface of the backcurve mold relative to the surface of the lens to lessen the adhesion therebetween to assist in separation of the molds, while leaving the lens in the frontcurve mold.      The conductive heating probe includes a convex heating surface which contacts and is the same general shape as a concave surface on the backcurve mold, and can also include a compliant heat conductor to conform to the concave surface on the backcurve mold. In one embodiment, the apparatus includes a conductive heating probe assembly having an n x m array of conductive heating probes which contact each backcurve mold of an n x m array of molds assemblies positioned in a support pallet.

Title: Verrouillage a pression differentielle pour lecteur de disque
Inventor: MICHAEL A DAVID
IPC: G11B21/02
Filed: 1996-11-06
Abstract: Ce dispositif de verrouillage pour actionneur à pression différentielle destiné à un lecteur de disque (10) comprend une partie corps rotative (52), une partie palette à air rigide (60) et un piège de verrouillage (62). Quand le disque de stockage des données (20) ne tourne pas, le dispositif de verrouillage maintient un ensemble actionneur de transducteur (32, 34) du lecteur de disque dans une position verrouillée en engageant l'ensemble actionneur dans le piège de verrouillage (62). Quand le disque tourne, l'ensemble actionneur (32, 34) bloque le flux d'air généré à la surface du disque, ce qui crée en aval une zone de basse pression. Le dispositif de verrouillage est positionné de façon que la palette (60) se trouve entre une zone de basse pression et une zone de pression ambiante. La différence de pression au-dessus de la palette (60) fait tourner le dispositif de verrouillage, ce qui libère l'ensemble actionneur (32, 34) du piège de verrouillage (62). Quand le disque s'arrête, la palette revient à sa position initiale et le piège de verrouillage (62) verrouille l'ensemble actionneur (32, 34).
