Title: Carousel-type apparatus for manufacturing caps made of plastics by compression molding
Inventor: ZUFFA ZENO
IPC: B29C43/50
Filed: 2000-08-28
Granted: 2006-08-17
Abstract: An apparatus for manufacturing threaded caps comprises a plurality of compression molding assemblies which are arranged on a rotating carousel and comprise an upper male mold half and a lower female mold half. The male mold half comprises a tubular element, a sleeve guided coaxially to said tubular element, and a punch guided in the tubular element and having a helical slot for forming the thread of the cap. The punch enters the female mold half and produces, together with it, the cap through compression of a dose of plastic material deposited in the female mold half. After the spacing of the punch from the female mold half, the removal of the cap from the punch occurs by way of a removal device, which comprises a ring gear associated with the sleeve and provided with a collar in sliding contact on the punch, a rod which can slide axially in a seat of the carousel and supports a gear meshing with the ring gear and connected to a motor drive mechanism. The rod is axially connected to the sleeve and is controlled by a stationary actuation cam which is suitable to impart axial movements to the rod. The cam and the motor drive mechanism are synchronized so as to move axially and rotate the collar so as to produce the unscrewing of the cap from the punch.

Title: Compensation for skewing of documents during a rotation through a finite angle
Inventor: KALISIAK MICHAEL S
IPC: B65H9/10
Filed: 1992-09-16
Granted: 1999-03-16
Abstract: The skew angle of a sheet (e.g., business form or other document) is detected by providing two sensors spaced from each other a known distance along a straight line perpendicular to the direction of conveyance of the sheet.  If there is a skew, the distance travelled by the sheet leading edge between sensings by the sensors is determined, and the skew angle calculated from its tangent.  First and second independent drive rollers under the sheet are driven in opposite directions of rotation to compensate for the skew angle.  The rollers preferably act in conjunction with a controller (computer) to not only reorient the sheet to compensate for the skew, but also to rotate the document through a significant angle (e.g., 90°) to give the sheet a second orientation different from its initial orientation (e.g., from portrait to landscape).

Title: Extrudable polyvinyl alcohol compositions containing polyethylene oxide
Inventor: FAMILI AMIR
IPC: C08L71/02
Filed: 1992-10-09
Granted: 1999-12-14
Abstract: An extrudable polyvinyl alcohol composition useful for packaging and molding applications is prepared by melt blending polyvinyl alcohol and thermoplastic polyethylene oxide to provide a product which has improved pH stability and salt solution solubility. Useful extruded articles prepared from such compositions include films and containers.      A method for extruding the polyvinyl alcohol composition comprises: adding sufficient energy to the polyvinyl alcohol composition to both melt it and essentially eliminate the polyvinyl alcohol crystallinity in the melt, and simultaneously removing energy from the melt at a rate sufficient to avoid decomposition of the polyvinyl alcohol.      The thermoplastic polyethylene oxide may be added to the polyvinyl alcohol before the polyvinyl alcohol is melted and its crystallinity eliminated or blended with the thus thermally treated polyvinyl alcohol and then melt extruding the polyvinyl alcohol/polyethylene oxide blend.
