Title: Combustion net
Inventor: SHIMIZU JIYUUICHI
IPC: F23G7/06
Filed: 1981-02-04
Abstract: PURPOSE:To promote combustion when ignited and remove noxious gas and soot moke during a normal combustion by a method wherein a combustion net is applied to have catalyst movably installed therein. CONSTITUTION:A combustion net is constructed such that the nets 3 and 4 are combined to each other to store the catalyst 2 in the supporting frame 1 so as to make a clearance 5 with a proper width, and one net 4 placed at a substantial central part 6 of the supporting frame 1 is buldged out at 14 toward the other net 3, and its circumferential part 8 is placed lower than the central part. Such net as described above is applied on a briquet stove 12 with its buldged-out part 14 being faced up, resulting in that the catalyst 2 in the bulged-out part 14 in the net 4 is dropped on the circumferential part 8 and the central part 6 has no catalyst 2 therein to cause a good air passage therein and thus an initial combustion of the briquet 13 may be promoted. When a proper high calory is produced after the combustion, the nets are turned up side down and again placed on the stove 12, resulting in that the catalyst 2 at the circumferential part 8 is returned back to the central part 6 to form an overall layer of the catalyst 2, so that non-combustion discharged gas from the briquet shows a secondary combustion when it is passed through the catalkyst layer 2 and then provides a complete diminishing of noxious gas and soot smoke.

Title: Method, system and network for multicast communication
Inventor: RASHIERU AN BONAA
IPC: H04L1/18
Filed: 1995-01-31
Abstract: PURPOSE: To provide a system for multicast tree communication of high reliability by transmitting an acknowledgment of multicast message reception to nodes in both directions across each transmission link. CONSTITUTION: Each of nodes A120 to E128 which are inerconnected by transmission links 121, 123, 125, and 127 forming a spanning tree transmits an acknowledgment of multicast message reception to all nodes directly adjacent to the node itself. If the node cannot receive the acknowledgment of multicast message reception from all directly adjacent nodes, it retransmits a multicast message considered to be lost. Consequently, each of nodes A120 to E128 can immediately release its buffer when receiving the acknowledgment from all directly adjacent nodes.

Abstract: PURPOSE:To stably perform combustion in which the production of NOx is small over a wide load range by sliding a movable ring valve along an outer liner to change an air distribution. CONSTITUTION:In a rated load state, a movable ring valve 25 is set approximately at the middle position of an outer liner 22, a fuel 6 is jetted in the inside of a liner 2 from an injection valve 3 to supply air 8 from a compressor and the like to the inside of a casing 1 through a supply opening 7.

At the time of starting and during load lowering, a regulation lever 26 is pulled to the lefthand side to move the movable ring valve 25 at the side of the injection valve along the outer liner 22. As the result, the distribution of the air 8 is modified so that the combustion air 14 is small and the dilution air 15 is large. Thereby, air fuel ratio is lowered to stabilize combustion.

Abstract: PURPOSE:To prevent clogging caused by solidification of molten metal by arranging a furnace body for storing molten metal, a pressurizing device for inner part of the furnace body and a chamber providing a pouring nozzle at upper part of the furnace body and providing a passage, which one end is opened at the bottom part of the chamber and the other end is opened at the bottom part of the furnace body. CONSTITUTION:At the time of pouring, the pressure in the furnace body 21 is set to the pressure at the time of receiving the molten metal with the pressurizing device 23 to supply the molten metal 24 into the chamber 26. The molten metal 24 supplied into a molten metal receiving trough part 29 is dammed with a weir part 33 and allowed to flow into inner part of the furnace 21 through the passage 27. When the head pressure from the molten metal surface 25 to the molten metal surface 36 reaches to the pressure at the time of receiving the molten metal, namely, at the time of detecting the molten metal surface 36 with a sensor 37, supplying of the molten metal is stopped. At the time of pouring, by operating the pressurizing device 23 to raise the pressure in the furnace body 21 to the pressure at the time of pouring, the molten metal 24 is pushed up into the chamber 26 through the passage 27. In the pouring trough part 29, the molten metal 24 goes over the weir part 33 and flows to pouring nozzle 30, 31 side and is supplied into a triangle ladle 35. The molten metal surface 25 in the furnace body 21 is lowered and the pressure at the time of pouring is gradually raised so as to correspond to the head pressure. By this method, the molten metal in the passage 27 is not solidified.
