IPC: B01J19/08
Filed: 2001-01-22
Abstract: The invention concerns a method for the surface treatment of polymeric substrates whereby the substrate is subjected to a dielectric barrier electrical discharge, in a gaseous mixture comprising a carrier gas, and a reducing and/or oxidising gas, at a pressure substantially equal to atmospheric pressure. The invention is characterised in that it comprises the following implementing conditions: when the mixture comprises an oxidising gas, the oxidising gas content in the mixture ranges between 50 to 2000 ppm by volume; when the mixture comprises a reducing gas, the reducing gas content in the mixture ranges between 50 to 30000 ppm by volume.

Title: Seam enhancements for seamed papermaker's fabrics
Inventor: KORNETT GLEN J
IPC: D03D15/00
Filed: 2002-10-02
Abstract: An on-machine-seamable papermaker's fabric produced by modified endless weaving includes machine-direction (MD) and first cross-machine-direction (CD) yarns. The MD yarns weave continuously back and forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. The MD and first CD yarns are interwoven with one another in a first weave pattern. The fabric also includes systems of second and third CD yarns. The second CD yarns are interwoven with the MD yarns along one of the two widthwise edges of the fabric between the system of first CD yarns and the seaming loops in a second weave pattern which may be different from the first weave pattern. Likewise, the third CD yarns are interwoven with the MD yarns along the other of the two widthwise edges of the fabric between the system of first CD yarns and the seaming loops in a third weave pattern which may be different from the first weave pattern. The second and third weave patterns may be the same as or different from one another. The second and third CD yarns may make the compressibility and permeability characteristics of the seam regions like those of the rest of the fabric, or may improve the stability, uniformity and orientation of the seaming loops at the two ends of the fabric.

Abstract: A noncontact method and apparatus for testing electrical circuitry which provides large improvements in both resolution and speed. The attributes of noncontact, high resolution, and speed are satisfied by using inexpensive lo w intensity resonant laser beams in a shroud has preferably comprising rubidiu m atoms in argon gas to create an electrically conductive ion channel microprobe. The conductive ion channel microprobe can be used to create an electrically conductive path between a circuit's test pad or point and signa l generation and detection apparatus. If the circuit's test pad or point is functioning properly, then the ion channel microprobe will complete the electrically conductive path, the signal generation device will produce a signal over the conductive path and the signal detection will detect or measure the signal. If the circuit's test pad or point is malfunctioning, th e conductive path will remain open and the signal detection device will not detect a signal.

Abstract: A two-dimensional matrix code (101), method of producing the code and a method and device for reading the code are presented. The code is a round, compact and distinct code that stores an error-corrected 64-bit number, embedded targets, and quality control information within a space small enough for imaging using a compact, hand-held code finder (107). The code incorporates white space (305) both between the data areas (303) and targets (301) for easy identification of the code and to aid in image processing, and within the data area to correct for errors that sometimes occur when printing using low-quality techniques. Additionally, the code includes features to correct for other printing errors, such as variations in printing press speed and intentional aspect ratio stretching to fill copy space. The code is thus robust enough to be incorporated within newsprint and is also easily imaged using specially constructed code finders. A code finder device and a method of using the finder for acquiring a code of the present invention is also presented. The finder is portable and easy to use, requiring no rotational orientation for correct acquisition. Several embodiments are described, in which the finder contains illumination and communications electronics and means to notify the user of correct operation of the finder.

Title: Board turner
Inventor: JOHANSSON JAN
IPC: B65G47/252
Filed: 2003-03-14
Abstract: The invention concerns a board turner (1, 31) for use on a conveyor (3) for transporting large volumes of boards. The conveyor (3) defines a plane for carrying boards (14) and the board turner (1, 31) has a rotation unit (4) and a gripping unit (7) mounted on the rotation unit (4).

Abstract: The present invention is directed to using a memory buffer to facilitate log catchup for online operations. Some designated areas of memory are allocated for one or more buffers for use during online operations (e.g. reorganization, create index, etc.). Concurrent update activities to the target object write informational records into the one or more buffer s. If the buffers become full, the informational records may be written to logs for persistent storage. After online operations finish building all or a suitable portion of the shadow object, l og catchup is performed by first applying activities in the informational records from the buffer an d thereafter applying activities from logs, if necessary. The invention helps solve the drawbacks of log catchup since the buffer contains only the information related to the target shadow object . Also it does not involve physical I/Os, as these records are all in memory.

Abstract: In a large-scale video-on-demand (VOD) system, the scalability and the provision of truly interactive functions are two difficult problems which have not been resolved satisfactorily. It is easy to provide fully interactive functions using unicast streams but these systems are limited in their scalability which affect the cost of service provisioning. Batching systems based on multicast streaming, on the other hand, can increase the scalability but it is difficult to provide interactive functions on these systems. This invention provides a media delivery system having a novel architecture aiming at serving millions of users in a metropolitan area. It features hybrid multicast-unicast streaming to achieve both scalability and full interactivity through the provision of distributed interactive servers, which cached the multicast media streams generated by the media servers. The interactive servers may also provide fault tolerant routing and error recovery.
