Title: Combustion chamber
Inventor: THOMPSON STANLEY PAUL
IPC: F23C3/00
Filed: 1996-06-05
Granted: 2000-04-25
Abstract: A combustion chamber has a vertically oriented body with an inner surface defining an inner combustion area.  A burner is disposed adjacent one end of the body so that the flame of the burner when lit will extend into the combustion area.  An annular insert is disposed in the combustion area and generally surrounds the flame of the burner.  The annular insert defines a secondary gas introduction zone for introducing secondary gases into the combustion area so that the recycled gases can be oxidized by the burner flame.  The insert has an inner surface presenting at least one  opening  for  allowing  fluid  communication  between  the introduction zone and the combustion area.  The opening is disposed tangentially to  the  insert  inner  surface to direct gases  in rotational motion to define a film of gases adjacent the inner surface of the combustion chamber.  The body of the chamber can include an outer shell and an inner cylindrical liner.  The outer shell has a generally horizontal inwardly extending support shelf.          The inner liner has an outwardly extending generally horizontal ridge positioned adjacent its upper end.  The ridge rests on the shelf to support the liner in a hanging fashion so that the liner can expand and contract when subjected to temperature variations.

Abstract: A priority queue is used to sequence template instantiations in compiling C+ + programs. If the analysis of a C+ + code fragment encounters a name that requires full instantiation and no matching full instantiation exists, the parse is terminated and rescheduled, and a full instantiation is scheduled as an antecedent of the failed parse. "Antecedent" means that the failed parse code fragment will not be reparsed until after the full instantiation has succeeded. Only when the full instantiation has succeeded will the terminated parse be reconsidered. Parsing full instantiations may causeadditional full instantiations. These are handled in the same manner; the additional instantiation is scheduled, and the current parse is failed and rescheduled. At the time of scheduling, the antecedent instantiation is marked with its dependent, so that the dependent chain give the chronology of the instantiation. This makes it easy to generate historical or "traceback" information for meaningful error messages.

Title: Hydrostatic self-loading controlled deflection roll
Inventor: BROWN DALE A
IPC: D21F3/08
Filed: 1995-08-10
Granted: 1999-10-26
Abstract: A hydrostatic self-loading controlled deflection roll has a central, hydraulically operated shoe which extends substantially the entire cross-machine width of the rotating roll shell (1), and two outboard shoes (24, 26, 28, 30) disposed, in the cross-machine direction, outside of the nip loading zone. The use of the outboard shoes (24, 26, 28, 30) permits the use of a single, full-length nip shoe (3) within the nip loading zone, which simplifies control and provides for more uniform temperature distribution. The outboard shoes (24, 26, 28,30) also provide better crown control. The outboard shoes (24, 26, 28, 30) are preferably disposed within a head flange (17, 18) area of the roll, at the location where spherical bearings would normally be present in a conventional roll. A bearing ring is disposed axially outside of the head flange (17, 18) and around a portion of a bearing box at either end of the roll for rotatably supporting the roll shell about bearings in the bearing box. A barrier seal is disposed between the stationary roll shaft and the roll shell (1) intermediate the bearings and outboard shoes (24, 26, 28, 30).

Title: Negotiated matching system
Inventor: SILVERMAN DAVID L
IPC: G06Q40/04
Filed: 1995-08-17
Granted: 2009-06-30
Abstract: A negotiated matching system includes a plurality of remote terminals associated with respective potential counterparties, a communications network for permitting communication between remote terminals and a matching station. Each user enters trading information into his or her remote terminal. The matching station then uses the trading and ranking information from each user to identify transactions between counterparties that are mutually acceptable based on the ranking information, thereby matching potential counterparties to a transaction. Once a match occurs, the potential counterparties transmit negotiating messages to negotiate some or all terms of the transaction.  Thus, the negotiated matching system first matches potential counterparties who are acceptable to each other based on trading and ranking information, and then enables the two counterparties to negotiate and finalize the terms of a transaction.

Abstract: The present invention relates to improvements in pipe connectors particularly but not exclusively for use in the oil industry for connecting metal pipe sections of a pipe string. The pipe connector comprising a tubular pin member having a generally frusto-conical outer peripheral surface and a tubular box member having a generally frusto-conical inner peripheral surface corresponding to the frusto-conical outer peripheral surface of the pin member and which overlies the frusto-conical surface of the pin member when the members are fully engaged together. The members are provided with inter-engageable annular projections and grooves on the said peripheral surfaces for axially locking the members together when they are fully engaged together, the projections and grooves being spaced apart along the surfaces. Means are provided for supplying hydraulic fluid under pressure between the overlying parts of the surfaces of the members when fully engaged together to expand the box member and/or contract the pin member to bring the projections out of engagement with the corresponding grooves and permit the members to be disengaged. The members include means for radially restraining the free end of at least one of the members of the connector and the extent of the radial overlap at full engagement of at least the projections and grooves in the region of the said free end of the one member and the corresponding inner end of the other member is reduced relative to that in the region of the centre of the connector.

Abstract: In a torque splitting device for distributing an input torque applied to an input member to a pair of output members adapted to be coupled with right and left driven wheels of a vehicle at an adjustable distribution ratio, the distribution ratio is determined in such a way that the understeer and oversteer tendencies of the vehicle under a positive or negative drive condition while turning a curve is appropriately controlled. In particular, it is highly desirable to prevent an understeer tendency from appearing while turning a curve. Therefore, when the vehicle is under a positive drive condition while turning a curve, a yaw moment is produced by an appropriate torque distribution which assists the vehicle to turn in such a way that the understeerg condition is canceled. Furthermore, when the vehicle moves on from a positively drive condition to a negative drive condition while turning a curve, a slight oversteer tendency is produced with a minimum time delay so as to avoid any transient phase of an understeer condition from appearing.

Abstract: A medical waste disposal system for contaminated products to be disposed having a hollow, disposal container and a housing enclosure which i s engageable with and covers the container. The housing enclosure has an openi ng and a tumbler which is pivotally mounted to prevent access to the interior of th e housing enclosure when a contaminated product is being deposited into the interior o f the disposal container. In one embodiment, upon dropping waste into the opening of the housing enclosure, the tumbler rotates to simultaneously close the upper opening in the housing enclosure and open a lower opening which allows the waste to dro p into the disposal container. After the waste has dropped, the tumbler, which is weighted, returns to its original position. When the disposal container reaches full capacity, the tumbler is blocked by the medical waste in the disposal container thereby preventing rotation to the open position. In an additional embodiment, a tumbler having an angled tip portion is provided which forms a lower passage to permit passage of waste while simultaneously blocking the accessibility beyond the interior of the housing enclosure without the need to fully rotate the tumbler to a closed position. The housing enclosure is also provided with a portion having a squared or slopin g contour to prevent sharps from passing or being ejected back through the opening of the container. The housing enclosure also includes a lid having a lock securely closing the medical waste disposal system for final disposal.
