Title: Network management system
Inventor: MISHRA RICHARD
IPC: H04Q3/66
Filed: 1996-12-04
Abstract: In order to satisfy a request for a connection path having a specified capacity between two specified terminations of a telecommunications network (91), a store (90) of routings and available capacities is searched to identify a connection path to satisfy the request; and if no connection path with adequate capacity is present in the store (90), a model (96) of the network is tested to identify suitable connection paths between the requested terminations, which are then added to the store (90), and allocated so as to satisfy the request. The search for suitable connection paths can take into account the hierarchical structure of the network (91) to identify suitable links to build up a path step by step. In a preferred arrangement the path is built up from each terminal point, at each stage using the link in the network which will bring the resulting ends of the two partial paths closest together, utilising, as a measure, a distance weighted according to the hierarchical level of the link.

Inventor: PARDUHN A PHILIP
IPC: A47J37/06
Filed: 1998-06-15
Abstract: A device and a method for cooking bacon and other strips of food which lose liquids during the cooking process. The device has a generally rectangular base and cover. The base has an arcuate cooking surface which is gently arched. The base also has a trough surrounding the bottom of the arcuate cooking surface along three sides for collecting the cooking liquids. The cover has an arcuate portion which conforms to the arcuate surface of the base. A skirt with recessed corners extends from the arcuate portion of the cover along three sides and cooperates with the trough in the base. Cooking liquids may be poured from the trough through pour spouts formed in the corners of the base in cooperation with the recessed corners in the cover. The device is held together by a fastening device which locks the cover to the base. A pair of handles formed along two sides of the base provide ease in handling the device and in pouring cooking liquids from the base. The method of the invention includes placement of strips of food on an arcuate cooking surface. The present invention produces evenly cooked, more healthful food and prevents curling and twisting of the strips.

IPC: A01G25/06
Filed: 1997-08-01
Abstract: An irrigation conduit (10) includes a plurality of emitters (11) spaced apart along its length. A conveyance channel (12) is connected to each emitter (11) and is long enough so that a distal end (14) of the conveyance channel (12) may be positioned at or just above the soil surface with the conduit (10) buried below the soil surface. Each emitter (11) or each conveyance channel (12) includes associated with it a flow control arrangement (30) to control the rate of flow through the conveyance channel (12) when water is applied to the conduit (10) at a desired pressure and flow rate. The flow rate through each conveyance channel (12) exceeds the local hydraulic loading rate of the soil adjacent to the conveyance channel (12). The rate in excess of the local hydraulic loading rate causes localized flooding and allows the water to spread out substantially across the soil surface prior to moving downwardly into the soil.
