Title: Method to make snow for insect control and device for making the same
Inventor: ELIASSON BERTIL
IPC: C01B32/55
Filed: 1999-07-09
Abstract: The invention relates to a method for bringing about the transformation of a medium (1) such as carbon dioxide or other gases or mixtures thereof into snow (2). In accordance with the invention, the aforementioned medium (1) and the snow (2) produced from it are caused to interact with surfaces of a snow-producing nozzle (4 2) extending from a discharge orifice (3) for the medium (1). The aforementioned medium (1), after exiting from the discharge orifice (3), is either permitted to expand into an elongated space which exhibits a uniform cross section. Or the medium (1) is also permitted to act against a number of obstructions (10, 11) in the form of flexible bristles (13) situated along the flow path of the medium as it flows out between the discharge orifice (3) for the medium (1) and an outlet (12) for the formed snow (2). The produced carbon dioxide snow (2) is intended for use in small animal pest decontamination. Means for producing snow (2) are included in the invention.

IPC: E21B23/01
Filed: 1999-07-23
Abstract: A method and apparatus for anchoring a tool within a cased borehole wherein at least one piston connected with respect to the tool includes an associated anchor shoe. The anchor shoe has a penetration means, such as a plurality of wheels having a sharp outer periphery, for engagement with the cased borehole. A  packer having a rigid component, such as a plurality of concentric rings, is connected with respect to the tool, opposite the piston. The packer may also have a sealing member for creating a sealed engagement between the tool and the cased borehole. When the piston is extended, the anchor shoe contacts the cased borehole and centers the tool with respect to the cased borehole. When the piston is extended, the packer also engages the cased borehole and maintains the position of the tool as well as creating a sealed connection between the tool and the cased borehole.

Title: Private branch exchange apparatus and accounting process method
Inventor: NAGASHIMA HIROAKI
IPC: H04M15/00
Filed: 2001-11-27
Abstract: Each time the time in a timer is re-set, a control section overwrites a difference integration value corresponding to the amount of the change from a reference value "0" in an registration memory of a memory section. When a call is sent from an extension to an outside line, the control section first reads out the difference integration value from the registration memory and stores on a management table the read-out difference integration value and call beginning time information in association with the call-sending extension. If the call between the extension and the outside line is finished, the control section executes an accounting calculation process for a call charge associated with the call-sending extension, on the basis of call end time information, the difference integration value stored in the registration memory at this time, and the call beginning time information and difference integration value associated with the call-sending extension, which are registered on the management table.

Title: Method and apparatus for computer system reliability
Inventor: NAIR RAVI
IPC: G06F9/30
Filed: 2002-01-15
Abstract: According to one embodiment, a multiprocessing system includes a first processor, a second processor, and compare logic. The first processor is operable to compute first results responsive to instructions, the second processor is operable to compute second results responsive to the instructions, and the compare logic is operable to check at checkpoints for matching of the results. Each of the processors has a first register for storing one of the processor's results, and the register has a stack of shadow registers. The processor is operable to shift a current one of the processor's results from the first register into the top shadow register, so that an earlier one of the processor's results can be restored from one of the shadow registers to the first register responsive to the compare logic determining that the first and second results mismatch. It is advantageous that the shadow register stack is closely coupled to its corresponding register, which provides for fast restoration of results. In a further aspect of an embodiment, each processor has a signature generator and a signature storage unit. The signature generator and storage units are operable to cooperatively compute a cumulative signature for a sequence of the processor's results, and the processor is operable to store the cumulative signature in the signature storage unit pending the match or mismatch determination by the compare logic. The checking for matching of the results includes the compare logic comparing the cumulative signatures of each respective processor. It is faster, and therefore advantageous, to check respective cumulative signatures at intervals rather than to check each individual result.

Title: Method and installation with smelting and reduction cyclone and a coupled lower furnace for utilising residual material containing iron and heavy metals and optionally iron ore
Inventor: FLEISCHANDERL ALEXANDER
IPC: C22B7/02
Filed: 2000-03-28
Abstract: The invention relates to a method and installation for utilising residual material which contains iron, heavy metals and optionally iron ore. In said method, the following take place: residual material and optionally the iron ore is introduced into a smelting cyclone (1) with a backflow and a base opening which has a narrowed section. Reducing agents and oxygen are additionally introduced into the smelting cyclone (1) and are subjected to swirling. Iron is reduced at least to FeO in the smelting cyclone (1), heavy  metals are reduced to metals in the smelting cyclone (1) and are converted into the gas phase by evaporation. The resulting gas which optionally contai ns heavy metals, the partially reduced iron and the slag are transferred to a furnace (5) which is directly adjacent. Energy, in electrical form is then supplied to said furnace (5), preferably using a direct electric arc. Reduci ng agents and oxygen, or oxygen-enriched air is then introduced into the furnac e (5) and the iron is completely reduced and melted in the furnace (5). The evaporated heavy metals are condensed outside the furnace (5), whereby the iron can be subjected to further processing and a deposition of the residual  materials is avoided.
