Title: Regular division of melt flow in extrusion of blown films
Inventor: CREE ROBERT E
IPC: B29C48/34
Filed: 1997-08-26
Abstract: An extrusion die having a plurality of die layers stacked one upon the other in a direction generally parallel to the central axis. Each of the layers has an annular flow distribution ring (40) having an outer generally cylindrical surface and an annular feed ring surrounding and engaging the outer surface of the distribution ring (42, 42d). At the engaged surfaces of the feed and distribution ring, the flow from the feed ring is divided into a number of substantially equal flow portions. Seals (43a, 43b) between adjacent engaged surfaces confine the flow between the circumferential surfaces of the feed and distribution ring. Half of the flow portions are directed to a recombination region (45, 46) on one side of the distribution ring (42d), and half are directed to a recombination region (45, 46) on the other side of the ring (42d). In recombining, weld lines are formed in high flow areas minimizing the deleterious effect of polymer degradation. Subsequently, the flows on the opposite sides of the distribution ring (42d) are recombined such that the weld lines from one half are first modified to exhibit lower flow and then are layered with non-weld line portions modified to exhibit higher flow from the other half. This further minimizes the negative effect of weld line areas. Flow from the two sides is regularly divided to yield even distribution of the combined flows.

Abstract: A portable modular outdoor playing arena having a plurality of modular floor panels and a plurality of generally vertically oriented modular side panels. The floor panels have a generally smooth flat upper surface and side surfaces that depend therefrom at approximate right angles. The floor panels are adjoined in a closed polygonalconfiguration to create a playing surface. The side panels surround and abut the floor panels and exert a compressive force on the floor panels to prevent lateral separation of adjacent floor panels. A seal forms a fluid tight connection between adjacent floor panels and at the juncture of the floor panels and the side panels. Each of the floor panels include adjustable legs to support the floor panels on the ground or on asub-surface. The legs are vertically adjustable to allow for the levelling of the floor panels so that adjacent floor panels can be individually levelled and supported to provide a level playing surface.

Title: Video signal recording and playback, rearranging dct coefficients across blocks from low to high frequency
Inventor: TOGASHI HARUO
IPC: H04N19/91
Filed: 1999-10-14
Abstract: In order to obtain a high-quality image when an encoded stream which is encoded using MPEG is played back at variable speed, a stream conversion apparatus is provided which converts an arrangement of DCT coefficients of a source encoded stream into an arrangement suitable for variable-speed playback. Specifically, a header part is separated from an elementary stream of MPEG, and DCT coefficients arranged from a low order of a spatial frequency to a high order are extracted by zigzag scan at intervals of a plurality of DCT blocks which form a macro block. These DCT coefficients are rearranged from a low order to a high order across a plurality of DCT blocks. The DCT coefficients rearranged in this manner are packed into a stream, and the separated header part is added, forming a converted elementary stream. This converted elementary stream is recorded. During high-speed playback, even if there is an error in the middle of the macro block, since decoding is possible using a low-order DCT coefficient, high-quality image video data can be obtained.

Title: Direct end-office atm trunking
Inventor: SYLVAIN DANY
IPC: H04L12/56
Filed: 1999-11-23
Abstract: An apparatus and method for providing direct trunking between a TDM switch and an ATM backbone network are described. The apparatus is an interface adapted to convert pulse code modulated data to ATM cells and vice versa. The interface is adapted to emulate a trunk peripheral of the TDM switch by communicating with a computing module of the switch using a messaging protocol native to the computing module. The interface may therefore be connected to the TDM switch without any modification of the computing module. The interface is connected directly to a serial link of a fabric interface of the TDM switch. The advantages include a reduction in the capital investment in equipment required to connect a TDM switch to an ATM backbone network and a reduced footprint for the equipment.
