Patent CA-2234149-A1 (CA)
Title: Improved railroad track switch heater
Inventor: WASHINGTON WILLIAM P
IPC: H05B3/00
Filed: 1997-08-04
Abstract: A high efficiency, direct conduction track switch heater (24) and associated spring clamp are disclosed. The heater (24) includes a generally blade-shaped jacket (68) dimensioned for mounting on the gauge side (26) of a fixed rail (22) at the track switch interface (62). The jacket dimensions reduce the likelihood of impact damage due to track switching while providing an enlarged heat transfer surface (66). The spring clamp presses the heater (24) tightly against the rail (22) while accommodating normal thermal expansions and providing a narrow profile for the overall heater and clamp assembly.

IPC: H04L12/56
Filed: 1997-12-29
Abstract: A switch that includes inputs for receiving cells connected to a first storage means for storing the cells received at the inputs. The first storage means includes a plurality of portions in which each portion is associated with an input. Additionally, each portion has a number of segments in which a cell may be stored. Additionally, the switch includes an address translation means for assigning a destination from a plurality of destinations to each cell received at the inputs. A second storage means is included in the switch. This second storage means has a number of sections in which each section is associated with a destination within the plurality of destinations and each section includes a number of segments. For each cell assigned a destination, the second storage means stores information identifying the location of the cell within the first storage means. This information is stored in a segment in the section associated with the destination assigned to the cell. A reading means is employed to transfer cells from the first storage means to their destinations by accessing each section within the second storage means to obtain information to identify the location of the cell in the first storage means that should be transferred to the destination associated with a particular section in the second storage means. The information within each section in the storage means is accessed in a first-in-first-out basis.

Patent CA-2249556-A1 (CA)
Inventor: SHIMONISHI HIDEYUKI
IPC: H04L47/629
Filed: 1998-10-05
Abstract: A network node includes a single buffer connected to a transmission medium. Detection circuitry receives an incoming packet and detects the virtual connection of the received packet. Control circuitry calculates a value of delivery instant for the received packet according to a minimum bandwidth assigned to the detected virtual connection so that vacancy of the transmission medium is reduced to a minimum if the received packet were delivered from the buffer onto the transmission medium at the instant of the calculated value. The calculated value is compared with a decision threshold assigned to the detected virtual connection. The received packet is stored into the buffer if the calculated value is smaller than the decision threshold or discarded if the calculated value is greater than the decision threshold.

Patent CA-2260541-A1 (CA)
Inventor: TUNG SHIH-HSIUNG STEPHEN
IPC: G06F12/08
Filed: 1999-02-01
Abstract: The present invention is directed towards a means to detect and reorder out of order instructions that may violate data coherency. The invention comprises a mis-queue table for holding entries of instruction data, each entry corresponding to an instruction in a computer microprocessor. The instruction data in each entry comprises: i) address information for the instruction; ii) ordering information for the instruction, indicating the order of the instruction relative to other instructions in the mis-queue table; iii) data modification information for the instruction, for indicating a possibility of modified data; and iv) out of order information, for indicating that a newer instruction has completed before the corresponding older instruction to the entry. The invention also comprises an out of order comparator for comparing an address of a completed instruction to any address information entries in the miss queue. If a completed instruction accesses the same address as another instruction, as indicated in the address information in the mis-queue table, and the completed instruction is newer than the matched instruction, the out of order field is marked indicating this condition exists. The invention comprises a modification comparator. This compares addresses from data altering events to those addresses in the entries in the mis-queue table. On a match, the modification field of the corresponding entry is marked to indicate this condition exists. When an instruction entry indicates that the corresponding instruction's data is modified, and that the instruction is out of order, all subsequent instructions are cancelled.

Title: Device for feeding printed products to a delivery station
Inventor: REIST WALTER
IPC: B65H29/02
Filed: 1997-05-22
Abstract: At a delivery station (1), printed products (4) are unwound from a product reel (6) and transferred to a transfer area (11) of a conveying system (12).  The latter has transport members (13) provided with controllable grippers (15) moved by conveying means (19, 19a) or by the force of gravity along a path of transport (14) designed as a closed loop. The printed products (4) are transferred at a delivery area (21) to a further processing device, for example an insetting or collecting drum (28). A buffer section (23), along which the transport members (13) are stored by reducing their mutual distance, is arranged upstream of said dispensing area (21). While an empty winding core (8) is exchanged for a full product reel (6), the supply of printed products (4) to the transfer area (11) is interrupted. During that time, the transport members (13) carrying printed products (4) are taken from the buffer section (23), ensuring a continuous supply of printed products (4) to the delivery station (21).

Title: Method, server and communications node for setting up fee-optimized communications connections
Inventor: KOTTHAUS ROLF
IPC: H04M3/42
Filed: 1999-06-15
Abstract: The present invention relates to a method for setting up fee-optimized communications connections by a communications device (EX1), a server for setting up fee-optimized communications connections and a communications node (EX1) therefor. The communications device provides a database, which, stores the fees accruing during the use of the communications paths (CON2A, CON2B) that can be used for setting up a communications connection. A first subscriber (SUB1) then logs on a call request to a second subscriber (SUB2) at the communications device. The communications device then determines a communications path (CON2A) between the first and second subscriber according to the overall lowest fees and sets up a communications connection between the first and second subscriber on said communications path. For this purpose, it is proposed that the communications device determines the fees accrued by said communications connection and charges them to a subscriber.
