Abstract: A supported or cast film of a polyhydroxyalkanoate polymer, such as a polyhydroxybuxyrate/valerate polymer, can be prepared by applying a layer of molten polymer to a cool (typically 4 to 20 °C) surface not substantially above the glass transition temperature of the polymer, so as to form a solid, glassy film with a high density of nucleation sites; subsequently the temperature of the film so formed is raised, for example to 40 °C or more, towards the optimum temperature for growth of the polymer's spherulites effectively separating the film formation/nucleation step from the crystallisation step (growth of spherulites around the nucleation sites). Smaller crystallites are formed, and the film has improved barrier properties.

Filed: 1995-10-12
Granted: 1999-09-28
Abstract: Threaded coupling for metal tubes comprising a sleeve (10) with two female threaded sockets (8,9) into which the threaded male elements (2,3) of two metal tubes are screwed. These male elements each have an unthreaded end zone terminating at an end wall (11,12). The two end walls press on each other in the screwed position, forming a metal-to-metal contact. The peripheral unthreaded area next to the end wall has a convex conical surface (14,15) which makes contact with a concave conical surface (19,20) in the sleeve, with positive interference to create a watertight metal-to-metal contact. Shoulder stops allow the male elements to be positioned precisely within a well defined zone of tolerance relative to the centre of the sleeve. Method of forming the coupling is also claimed by screwing a first male element into the female until the coupling engages and its advance is blocked by the two shoulder stops making contact, then screwing in the second male element until the two end walls meet.

Title: Carrier with reflective means to block reading of bar code
Inventor: WATTS LESLIE M
IPC: B65D71/50
Filed: 1995-12-27
Granted: 2001-08-28
Abstract: A novel carrier for carrying a group of items, such as cans, bottles or the like which hold beverages, foods or the like, is made of a substantially transparent, plastic material having micro-embossed partial cube-corner type retro-reflector elements on a surface of the carrier.  Each item includes an individual machine readable bar code thereon which is at least partially covered by the reflector elements.  The package has a machine readable bar code thereon which is not covered by the reflector elements on the carrier.  The reflector elements prevent the individual bar codes on the items from being read by a typical bar code reader beam by reflecting the light emitted from the bar code reader so the light cannot penetrate the carrier and read the bar code underneath the reflector elements.  The bar code on the package, which when scanned by the bar code reader beam will retrieve package information, can be read by the reader since it is not covered by the reflector elements.

Granted: 2004-08-17
Abstract: The present invention relates to a method for disintegration of thermoplastic elastomeric materials containing fibres, wires or the like. This method comprises the following two steps: subjecting segments of the elastomeric materials to temperatures able to bring the segments into a brittle glass-like state (by means of a freezing chamber), and gradual disintegrating of the frozen segments by disintegrating means provided to separate the segments from the wires and fibres. This disintegration is effected by means of a bending force applied to the frozen segments causing them to break into small particles while the wires and fibres remain substantially intact. After the disintegration, separation of the small particles, wires and fibres takes place by separating means. The disintegrating means comprises a roll means, where the roll means is provided with mating bending surfaces spaced apart from each other at predetermined distances and facilitating maximum bending and breaking of the frozen segments being advanced between the roll means. The roll means may comprise two sets of rolls, where distance between the first set of rolls is bigger than the distance between the second set of rolls to facilitate gradual breaking of the frozen segments. The mating bending surfaces are a plurality of semi-spherical heads, where the heads are spaced from each other in such a way that heads on the mating surface of one roll are mating with a space between heads on the mating surface of another roll.
