Title: A process for the production of plasminogen activators in prokaryonts
IPC: C12N15/58
Filed: 1987-04-16
Abstract: In order to produce, in a procaryote cell, a plasminogen activator by expressing a c-DNA coding for this activator, which c-DNA is incorporated in a vector that is suitable for the host cell, a strictly controlled vector is used so that its replication cannot be dissociated, or can only be temporarily dissociated from the replication of the chromosome of the host cell. Its culture is carried out in conditions such that no laxity occurs in its control. Plasmids that are particularly suitable for carrying out this process are disclosed.

Title: Optimum carton hold-down element for rotary feeders
Inventor: MONCRIEF FRANK
IPC: B31B50/80
Filed: 1996-04-19
Abstract: A hold-down element for a rotary feeder has a curved elongated member for continuously contacting an article during rotation of a rotary head. The curvature of the hold-down element is selected so that the distance from the elongated member to the rotary head increases from the point of initial contact to the final contact point on the elongated member. The hold-down element preferably maintains contact for at least 20 DEG  of rotation of the rotary head, and thus maintains contact with the article for an extended period of time. The hold-down element is attached to a vacuum shaft on the rotary head, and is prevented from rotating relative to the vacuum shaft by a keyway on the hold-down element and a key on the vacuum shaft. The hold-down element, however, is permitted to travel transversely along a longitudinal axis of the vacuum shaft in order to accommodate different shaped articles.
Patent ZA-989698-B (ZA)
Title: Inhalation device
Inventor: CLARKE ALASTAIR ROBERT
IPC: A61M5/172
Filed: 1998-10-23
Abstract: An inhalation device which contains powdered medicament in the form of a medicament compact is provided with a seal comprising a partial ring between the outer wall and inner mandrel of the medicament compact chamber. The medicament is dispensed by abrading the medicament compact by turning the compact relative to the inner mandrel against a blade. Despite only extending around part of the circumference of the mandrel the seal prevents leakage of loose powder from the compact chamber to the rest of the device. The sealing means also provides a frictional braking force on the medicament reservoir sufficient to prevent movement of the medicament reservoir when the drive mechanism for the reservoir is returning to its starting position without making the device difficult to operate by a child or infirm adult.

Title: Method and apparatus for packaging discrete articles
Inventor: GRANT DAVID BARRATT WILSON
IPC: B65B9/067
Filed: 1999-06-18
Granted: 2002-02-20
Abstract: A method and apparatus for packaging discrete, substantially planar articles in envelopes. A succession of packages are deposited on one side of a longitudinal centre line (13) of a continuous web (11). As the web moves in the longitudinal direction, it passes between a pair of spaced apart guide bars (15) which urge the side of the web either side of the longitudinal centre line (13) upwardly about the centre line (13) to fold the web about the article. When the web has been fully folded together about the articles, the web side portions are sealed together around the articles to define pockets containing one or more of the articles, which pockets can then be cut from the web to form discrete envelopes containing one or more articles.

Title: Toggle bolt device
Inventor: KAYE GORDON E
IPC: F16B21/00
Filed: 2000-01-31
Granted: 2002-05-15
Abstract: An improved fixed positionable toggle bolt device for fastening objects to a substrate comprising a metal anchor member having a nut portion and a selectively frangible positioning and holding assembly engaged with the metal member. The assembly comprises two elongated control legs, with the first ends of the control legs being pivotally attached to the metal member. The second ends of the control legs are movably attached to each other by an elongated undercut element interference, with movement of one leg relative to the other, effected by finger tip sliding, causing the metal anchor member to pivot from substantially in line with an insertion aperture in the substrate, to a position parallel to the substrate when the second ends of the control legs are aligned with each other. A positioning collar is engaged with both legs, holding them in place and is movable along the respective lengths of the legs. The legs are arcuate in cross section with a series of axially extending closely spaced rib-like teeth within the arcuate concavity. The collar is adapted to conform to the arcuate concavity together with a step tooth section to provide a one way ratchet with the legs. Once the metal member is positioned behind the substrate and abutted thereto the collar is ratcheted to a snug fit with the substrate and the legs are broken off to thereby fix the anchor in place.

Granted: 1994-10-26
Abstract: A chaise lounge recliner chair (300) which incorporates an intermediate leg support member (312) for providing support to the thighs and areas behind the knees of the legs of an occupant of the chair. The intermediate leg support member (312) is connected to a portion of the seat (306) of the recliner chair and a portion of the leg rest member (310) of the chair. When the leg rest member (310) is in an extended position the intermediate leg support member (312) provides a normal slightly convex support surface. As the seat back (302) of the chair is reclined, it causes the seat member (306) to be extended outwardly which causes the intermediate leg support member (312) to assume a pronounced convex surface. A plurality of elastic straps (324) are further included and disposed between the seat (306) and leg rest members (310) to prevent the intermediate leg rest member (312) from crowning downwardly relative to the chair frame when the leg rest member (310) is in it extended position. <IMAGE>
