Abstract: A method for drying wood plates using hot plates according to the present invention is an improvement of a method comprising inserting wood plates respectively into spaces between a plurality of hot plates layered in steps.     In a method for drying wood plates using hot plates according to the present invention, while the wood plates are held, pressed and heat dried by and between the hot plates, a part of spaces between the hot plates are opened and dried wood plates are discharged from the opened spaces between the hot plates and undried wood plates are inserted into the opened spaces between the hot plates.  Therefore, while the hot plates from which wood plates are not discharged or between which wood plates are not inserted now are kept in pressed state, a part of spaces between the hot plates are opened and dried wood plates are discharged from the opened spaces between the hot plates and undried wood plates are inserted into the opened spaces between the hot plates. Only the hot plates from which wood plates are discharged or between which wood plates are inserted are opened, and other hot plates are kept in pressed state.

Abstract: L'invention concerne un procédé de simulation, dans un réseau, d'une architecture "serveur" à partir d'une architecture "client" d'une première machine (PS) pour l'exécution d'appels de procédure à distance RPC émis par au moins une machine d'architecture "client" (CL). Selon ce procédé la première machine (PS) émet préalablement un appel RPC vers une troisième machine d'architecture "serveur" (RE) utilisée comme machine relais entre la première (PS) et la deuxième (CL) machines, cet appel RPC ouvrant un contexte de communication pour la suite des échanges alors que la première machine (PS) se bloque dans l'attente d'un retour de l'appel RPC. Lorsque la seconde machine (CL) émet un appel RPC représentatif d'une fonction déterminée à exécuter par la première machine (PS), cet appel est transmis vers la machine relais (RE) qui après reconnaissance de la fonction le retransmet vers la première machine (PS) par retour de l'appel RPC bloqué. La première machine (PS) demande alors les paramètres d'entrée de la fonction à exécuter connus de la machine relais (RE) puis exécute la fonction dès leur réception en fournissant comme paramètre de sortie le résultat à la seconde machine (CL) via la machine relais (RE).

Title: Immunoassays for anti-hcv antibodies using antigens with conformational epitopes
Inventor: CHIEN DAVID Y
IPC: G01N33/569
Filed: 1993-07-02
Granted: 2003-02-11
Abstract: Immunoassay methods utilizing HCV envelope antigens that contain conformational epitopes reactive with antibodies in serum from infected individuals are useful for screening and diagnosis. These antigens detect antibodies that are not detected by denaturated HCV envelope antigens. In addition, these HCV envelope antigens comprised of conformational epitopes are more immunologically reactive than a number of other HCV antigens. This is the first evidence that conformational epitopes may be involved in the immunologic response to HCV antigens.

Abstract: A receiver, an automatic gain controller suitable for the receiver, a control signal generator suitable for the automatic gain controller, a reception power controller using the automatic gain controller and a communication method using the receiver.          The instantaneous power of a  received signal output from a variable gain amplifier or attenuator is detected by a power detector.  The detected instantaneous power is quantized by a comparator and filtered through a random walk filter.  An up-down counter counts up or down in accordance with the increment signal or the decrement signal obtained by filtering.  In this manner, error in the gain control of the variable gain amplifier or attenuator is obtained.

Filed: 1995-09-26
Granted: 2002-01-08
Abstract: A vertical tubeless boiler relates to the generation of hot fluids. A boiler is presented with improved efficiency and capacity causing less pollution and noise wherein the water jacket, formed by inside pipe-combustion chamber inserted into the outside pipe with the upper header and the bottom header placed between and at each end of the pipes, is surrounded with hot combustion products generated in the combustion chamber by burning oil or gas. Passages are arranged to make four passes of hot combustion products. The first pass is downward below the burner head and inside the inner pipe of the water jacket. The second pass is upward by one section of the external wall of the water jacket.The third Pass is downward by two sections of the external wall of the water jacket. The fourth pass is upward by remaining section of the external wall of the water jacket. The external wall of the water jacket is conducted by fins pitched to increase the heat flow from the hot gases to the heated fluid. The fins are wrapped around with the flue jacket which is gas tight welded to the flue dividers, the nozzle the boiler support plate and to the sleaves. The flue jacket is wrapped with ceramic fibre to insulate hot combustion products. The air for combustion is supplied through a nozzle placed between the inside pipe of the water jacket and the outside wall of the water jacket and bellow the top header of the water jacket. The burner head is radially positioned to the nozzle- air supply. The air for combustion is supplied by the centrifugal fan with radial blades.

Abstract: An asynchronous data transfer and source traffic control system includes a bus master (100) and a plurality of bus users (112, 114, 116) coupled to a bidirectional data bus (120-128). The bus master (100) provides two clock signals (120, 122) to each bus user (112, 114, 116), a system clock (120) and a frame clock (122). The frame clock designates the start of a frame. A frame format preferably includes fifteen or sixteen system clock cycles, the first of which is designated the request field and the last of which includes a grant field. One or more other cycles may be assigned control and/or routing information and the remainder of the cycles comprise a data field of fixed length. During the request field, any number of bus users (112, 114, 116) may request access which is received by the bus master (100). During the grant field, the bus master (100) grants access to a selected bits user (112, 114, 116) for the entire data portion of the next frame. Which user (112, 114, 116) is granted access to the next frame is determined according to an arbitration algorithm in the bus master (100) which may be unknown to the bus users (112, 114, 116). The asynchronous data transfer and source traffic control system has particular application in accommodating the transfer of the contents of ATM cells used in BISDN systems.
