Abstract: La présente invention concerne une coquille refroidie pour coulée continue (1) permettant la coulée de métal, notamment d'acier, se présentant sous un format de brames, ayant dans ce cas notamment une épaisseur comprise entre 40 et 400 mm et une largeur comprise entre 200 et 3500 mm, comprenant des parois de coquille constituées de plaques (7, 7.1) dans lesquelles sont formés des canaux à liquide de refroidissement. L'invention a pour objet d'améliorer ladite coquille de sorte que la contrainte thermique peut être homogénéisée sur la hauteur de la coquille c'est-à-dire que le profil thermique peut être homogénéisé sur la hauteur de la coquille, la température superficielle de la coquille au niveau de coulée pouvant ainsi être réduite. A cet effet, la largeur (26.1) des canaux à liquide de refroidissement (29) diminue, en fonction du profil de flux thermique (2.1), dans la direction de coulée, sur la hauteur de coquille (13), de l'entrée de coquille (1.1) à la sortie de coquille (13.2).

IPC: G11B27/32
Filed: 2002-07-12
Abstract: A method for recording video information for controlling video information copy limit information when copying data recorded on a recording medium to another recording medium. By detecting copy limit information (CCI) or a watermark (WM) of an AV stream to be input, it is checked whether the conten t of the copy limit information or the watermark has been changed. Change poin t information of the copy limit information or the watermark and the content o f the copy limit information or the watermark are fetched. According to the change point information fetched, control information is generated for controlling the copy limit information. When the input signal has ended, a code for preventing altering is calculated, it is confirmed that the copy limit information or the watermark has not been altered, and the control information generated is recorded together with the video information to the  recording medium of copy destination.

Title: Delay lock loops for wireless communication systems
Inventor: SINDHUSHAYANA NAGABHUSHANA T
IPC: H04B7/08
Filed: 2002-01-17
Abstract: Techniques for deriving sample timing for multiple signal instances received on multiple antennas for a given propagation path. In one scheme, a DLL is maintained for each path, and each DLL tracks the timing of the best signal instance for the assigned path. In another scheme, a DLL is maintained for each path, and each DLL tracks the average timing of the multiple signal instances for the assigned path. To reduce timing jitter, the SINR of a signal instance may be estimated for a number of different time offsets. The loop filter for the DLL is initially updated in the normal manner. If a change in the time offset used for the sample timing is detected, then the SINRs for the new and prior offsets are compared. The new time offset is used if the associated SINR is better. Otherwise, the prior time offset is retained and used.

Title: Coated gypsum board products and method of manufacture
Inventor: COLBERT ELIZABETH A
IPC: B32B5/16
Filed: 2002-01-25
Abstract: A gypsum board is coated with a coating (32) during the manufacturing process to form a coated gypsum board. Coatings are applied to wet gypsum boards before being dried (325) in the oven and coating penetrates through at least a portion of the facing sheet and into the gypsum core of the gypsum board.  Rapid coating compositions allow faster installation; quick setting compositions provide for more durable finishes. Either coating may be made lightweight by addition of perlite and may have enhanced finish appearance by incorporating pigments. A coated gypsum board can be fastened to a support structure to form a wall and the seams between adjacent coated gypsum boards can be taped and finished using a joint compound having a composition substantially similar to the composition of the coating. Overall, the resulting coated gypsum board and the method used to produce it help to improve final finish appearance and to reduce manufacturing time and costs.
