Title: Dryer-section concept and method in the drying of a paper/board web
Inventor: JUPPI KARI
IPC: D21F5/04
Filed: 1996-04-12
Abstract: The invention concerns a dryer-section concept of a paper/board machine and a method in the drying of a paper/board web (W). The dryer section comprises a number of drying cylinder groups (R I...R N), which comprise a single-wire draw, on whose support the web (W) is guided so that it meanders as loop-shaped from a drying cylinder onto a suction cylinder. The web (W)/the wire (H) is guided so that the web is placed against the face of the drying cylinder and the wire is placed outside. In the dryer-section concept, the web (W) is passed from one drying cylinder group (R I) into the next dryer group (R II) and further. According to the invention, at least some of the drying cylinders (K'1, K'2, K'3) include impingement units (100, 101, 102) or equivalent in connection with them, through which units a heated medium, preferably air or steam, is passed through the wire into connection with the web (W) so as to produce a two-sided drying effect and to increase the drying capacity.

Title: Digital communications switching fabric
Inventor: BRETHOME JEAN-CLAUDE
IPC: H04L12/56
Filed: 1997-11-04
Abstract: A type of switching fabric for exchanging variable-size frames of digital information between frame processors coupled directly or indirectly to one or more digital communication lines. It comprises one or more multi-line serial communication controllers (MSCCs), and a backplane providing a full mesh of serial point-to-point bi-directional links between each MSCC, and, in a loopback, from each MSCC back to itself. The MSCCS collectively manage the transfer of variable-size frames between the frame processors. To transfer digital information from a source line to a destination line, a frame processor coupled to the ingress line drives the switching hbric by signaling its MSCC that there is information. The ingress MSCC then switches the digital information through the backplane to the MSCC serving the frame processor coupled to the egress line. The switching fabric uses a clocking scheme that makes possible high throughput rates.

Title: An electronic lottery system and its operating method and computer-readable recording medium in which the electronic lottery program code is stored
Inventor: SAKO KAZUE
IPC: G06Q50/00
Filed: 1998-01-19
Abstract: Using a sealing function the parent system seals the random number x which is generated by a random number generation means, and it, along with both the sealing function and the result calculation function, is made public by a setting publication means.  Each of the subsystems (i ) which will participate in the lottery sends the random number, which is a response, generated by its random number generation means.  The result calculation means of the parent system calculates a lottery result by applying the response ri and the initial value x to the result calculation function, and makes public the lottery result, the initial value x and the response ri.  Each of the child subsystems (i ) receives this information, and the result verification means determines whether the sealed initial value equals to the value calculated by applying the initial value to the sealing function, and whether the response of each of the child subsystems is recorded, and whether the lottery result equals the value calculated by applying the result calculation function to the initial value x and the response ri.

Patent CA-2238114-A1 (CA)
Title: Packet switching system, packet switching network and packet switching method
Inventor: TAKASE AKIHIKO
IPC: H04L47/43
Filed: 1998-05-14
Abstract: Upon initialization, a VPC is set up between edge nodes. A control processor of each node creates an IP address/VPC mapping table using IP routing information and an address mapping table mapping correspondence between IP addresses and ATM addresses and supplied by a network management system.  A gateway assigns a VCC to each packet input to the network.  A sending-side edge node inputs the packet to the VPC corresponding to its destination by referring to the IP address/VPC mapping table.  A transit node performs packet switching over VP.  A receiving-side edge node transfers each packet to the gateway corresponding to its destination.  If a series of packets meet a predetermined condition in a given edge node, its control processor sends VCC information to input interfaces of the edge node so that the packets are switched by an ATM switch in the edge node without intervention of the control processor.

Title: Apparatus for weighing small articles such as gelatin capsules
Inventor: CANE ARISTIDE
IPC: B07C5/16
Filed: 1997-02-17
Abstract: The capsules or other products (1) are fed by suitable means (4, 5, 10, 11, 12, 112, 13) in single file and taken up one at a time by a tangential wheel (16) which is fitted with reference teeth (18), with each tooth supporting one product, and has suction holes (19) so as to retain the said products. When the products reach or are about to reach a position above suitably shaped associated weighing heads (24), the suction that holds them against the wheel is cut off and the said products fall, positioning themselves correctly on the said heads, aided in part by the halting action exerted by the teeth in front. The products deposited on the heads are weighed and are then discharged by the pushing action of the wheel (16) teeth (18) which place the next product on the said heads. A chute (25) collects the products ejected from the heads and a deflection plate (26), controlled by the central processing and control system (32), separates products of the correct weight from those to be rejected. Several apparatus of this type are placed next to each other so as to obtain high production rates.
