Abstract: A heat  treating  furnace  including  a  housing defining a chamber, a heavy high thermal capacity cast link endless conveyor belt positioned within the chamber for moving articles to be heat treated through the chamber, a narrow elongated vestibule passage extending forwardly from the chamber, and a light low thermal capacity wire mesh endless belt conveyor extending from a furnace loading location forwardly of the vestibule passage through the vestibule passage to a location within the  chamber in vertically spaced overlying relation to the forward end portion of the cast link conveyor.  The vestibule passage minimizes loss of heat treating atmosphere from the furnace chamber, and curtains are provided in the vestibule passage to  further minimize  atmosphere  loss.  The  light  feed conveyor is run at a higher linear speed than the heavy furnace conveyor so that the load on the feed conveyor and the vertical profile of the parts on the feed conveyor may be reduced.  The low mass and low thermal capacity of the wire mesh feed conveyor also minimizes the furnace heat loss occasioned by the continuous movement of the feed conveyor  between  the  heated  furnace  chamber  and  the relatively cool outside atmosphere.

IPC: H04L12/70
Filed: 1997-12-29
Granted: 2002-11-12
Abstract: In an active/standby routing system for establishing a active route and the corresponding standby route in an ATM network, a node transmits, as a connection signaling message,  a connection pair identifier which is unique to a combination of the active and the standby routes together with information which is indicative of either of active and standby routes. The active and the standby routes are quickly switched from one to another even when one of the routes is to be recalculated due to a trouble in the other route.       The connection signaling message is transmitted to both the active and the standby routes from the first node.  A repeating node receives the message, sets the route indicated by the information indicating an active or standby route in the received message and thereafter transmits the message. An end node records information on paired active and standby routes from the connection signaling message received through the active and standby routes to maintain correspondence between active and standby routes.

IPC: G06F17/30

Granted: 2001-05-15
Abstract: The invention concerns a general-applicability data-base system (DBS) for the storage, retrieval and manipulation of scan data, i.e. arrays of any (fixed or variable) size and dimensions and of any basic type. The invention is characterized by the strict separation of the logical (conceptual) and physical levels in order to ensure data independence, i.e. the possibility of addressing scan data irrespective of their physical storage structure, coding or state of compression. Depending on the data format required by the application, the DBS undertakes, in transparent fashion, the required conversion and (de)compression, taking into consideration accessing- and transmission-optimization aspects. At the conceptual level, the explicit definition of array structures provides the DBS, via a data-definition language (DDL), with knowledge of the complete array semantics. An orthogonal enquiry language (DML) includes array-specific primitives as well as operators which can be combined in any way to formulate optimizable DML expressions and predicates. Standard functions make explicit format conversion possible. At the physical level, a memory architecture based on a combination of array tiling and a spatial access structure (geo-index) permits efficient access to arrays and sub-arrays as well as the distribution of arrays over several, in certain cases heterogeneous, storage media. The invention is suitable above all for scanning applications with high requirements on functionality, data volume, network capability and access time, in particular for distributed, open multi-media systems.

Abstract: A wrapper-type box for transporting a sandwich. The box is formed from a one-piece flat blank of stiff but foldable cardboard. The blank has a main part with a plurality of parallel fold lines which divide the main part into four adjacent side walls. The main part is folded about the fold lines to assume an elongate tubular body of rectangular configuration. An edge flap and a top wall overlap and have cooperating locking tabs and slots to secure the main part in an assembled condition.      The edge flap also has a looplike handle formed therein.      The one-piece blank also includes a pair of flaps associated with and projecting outwardly from each end.      To effect closure of the end of the tubular body, the pair of flaps are folded inwardly into the box interior through a sufficient angle so that a tab on one flap passes over the other flap and projects into a slot provided on the other flap. The manual folding force is released, and the memory of the flaps causes the flaps to swing outwardly and effectively engage the tab within the slot and lock the flaps together.
