Title: Object-oriented remote procedure call networking system
Inventor: GOLDSMITH AMY M
IPC: G06F13/00
Filed: 1994-03-11
Abstract: Object-oriented client-server facility (CSF) and networking service facility (NSF) interfaces implement communication between application programs residing in client and server nodes at a distributed services network.  The CSF interface includes remote procedure call (RPC) objects for invoking and responding to service requests at the nodes and application programming interface (API) objects for transporting those requests between the nodes.  However, the API objects only provide communication  transports within a node. Accordingly, the API and RPC objects interact with dynamically-configurable protocol stacks within the NSF interfaces to complete the transport mechanism needed by an application program on the client node when accessing services on a remote server node.

Title: Gas staged burner
Inventor: BRAIS NORMAND
IPC: F23Q9/00
Filed: 1996-03-01
Abstract: A burner is provided for heating a stream of combustion supporting gas, like air. The burner has a main feed pipe extending across the stream of combustion supporting gas. The main feed pipe has an inlet for receiving a fuel gas from a fuel gas source, and at least one outlet for producing a main jet of fuel gas substantially in the direction of the stream. The  burner  also  has  two  parallel  auxiliary  feed  pipes extending across the stream of combustion supporting gas, at a predetermined distance downstream from the main pipe and on each side of the main jet. Each of the auxiliary feed pipes has an inlet for receiving fuel gas from the fuel gas source, and at least one outlet for producing an auxiliary jet of fuel gas in the direction of the stream. The burner further has two bluff-body devices in  front of the outlets of both the auxiliary feed pipes respectively. Each of the bluff-body devices has a hole aligned with each corresponding outlet in order to produce a stable pilot flame adjacent to the main jet of fuel gas for ignition thereof. This burner is useful since it allows for a better mixing of the fuel gas with the stream of combustion supporting gas. Such in turn allows for a better combustion  of  the  fuel  gas  and,  hence,  a  reduction  of pollutant emissions.

Patent CA-2175294-A1 (CA)
Inventor: SEWELL FREDERIC D
IPC: F24F6/00
Filed: 1996-04-29
Abstract: A water spray-based air purification system having a humidification portion and a dehumidifying portion is operatively installed in an air handling unit used to recirculate air within a conditioned space. A blower within the air handling unit housing operates to draw return air into the housing, flow the air across the entire air purification system, and then discharge the purified and humidified air back into the conditioned space. A water spray portion of the purification system is served by a pump forcing water from a sump structure through a filter, with the spray water draining back into the sump after cleansing air traversing the purification system. Upon a sensed demand therefor, an additive injector adds suitable chemical treatment material to the sump water, and a water pollutant monitor structure operates to backwash the filter upon sensing an undesirable pump back pressure increase or a buildup of particulate and gaseous pollutants in the sump water. The operation of the air handling unit and its associated air purification system are automatically monitored and regulated by a programmable air quality and monitoring and control system which is coupled to multi-parameter sensing apparatus that continually detects temperature, humidity and gaseous and particulate pollution levels present in the conditioned space or the air being delivered thereto from the air handling unit.

Title: Turbulence inhibiting tundish and impact pad
Inventor: SAYLOR KARL J
IPC: B22D41/02
Filed: 1994-10-17
Abstract: A tundish and, more specifically, an impact pad is formed with a bottom impact surface and includes an outer side wall extending upwardly therefrom which fully encloses an interior space or cavity having an upper opening into which molten metal is directed from a ladle shroud. The outer side wall of the pad includes an inner surface extending from the bottom impact surface to the opening of the pad. The inner side wall surface includes an annular portion which extends inwardly and upwardly toward the opening of the pad. In the preferred embodiment, the inner side wall surface curves continuously from the bottom impact surface to a vertical wall defining the opening of the pad. The pad redirects the pouring stream back into itself causing the counter current flows to slow each other down thereby minimizing turbulence and inhibiting high velocity flow within the tundish. The upward flow is further is advantageously directed away from the incoming pouring stream toward the surface of the bath.

Title: Methods for sub-surface fluid shut-off
Inventor: WEHUNT CLYDE D
IPC: E21B33/138
Filed: 1995-11-08
Abstract: Methods for reducing or eliminating undesirable in a producing well by releasing a plugging material below an obstruction (35) placed in the producing zone. The obstruction (35) is placed near the base of a desirable fluid-producing interval. The plugging material flows outward to form a barrier to the flow of undesirable fluids into the desirable fluid-producing interval. For most applications, a buoyant plugging material is used so that undesirable fluid crossflow carries the plugging material to the location where it is needed to form a barrier to the undesirable fluid production. The present invention can be used in gravel-packed wells, open hole wells, or cased-hole wells. The present invention can also be used with a pair of obstructions (28, 30) with a plugging material released between them to shut off multiple intermediate intervals producing undesirable fluids. In some circumstances, the present invention can be used with a pair of obstructions (29, 30) without the need for a plugging material to be released between the obstructions (29, 30). Likewise, the invention can be used in vertical, inclined, or horizontal wells.

Patent CA-2184018-A1 (CA)
Title: Method for logical network design in multi-service networks
Inventor: MITRA DEBASIS
IPC: H04L12/56
Filed: 1996-08-23
Abstract: A method is described for network optimization based on a multirate, circuit-switched analysis. Network loss probabilities are determined as a solution of a set of fixed point equations and the sensitivity of network performance, as a function of offered load and loss probabilities, is determined as a solution to a set of linear equations. Because the numerical complexity of solving both the fixed point equations and the sensitivity equations is of an order which renders an exact solution computationally intractable, an asymptotic approximation is applied which yields a solution to the network loss probabilities and network sensitivities. A global optimization procedure is then applied using an iterative, steepest ascent optimization procedure to yield a set of virtual path routings and capacity allocations.

Title: Overpull shifting tool
Inventor: GOMEZ ALFREDO
IPC: E21B47/09
Filed: 1996-03-05
Abstract: A shifting tool is disclosed which allows movement of a shifting sleeve, to be followed by an additional force applied to ensure complete stroking of the shifting sleeve. This is accomplished by a shifting key to normally shift the shifting sleeve, followed by an overpull key which engages while the shifting key is still engaged. Once a predetermined force has been applied to the overpull key, the force applied from the surface is removed so that the tool may disengage from the sleeve. Subsequent manipulation, without necessarily any removal from the wellbore, if it does not result in a reengagement, provides feedback that the shifting sleeve has, in fact, shifted its full stroke. An emergency release is available which actuated by an overpull force beyond a predetermined level, applied while the overpull key is engaged for an emergency release from the shifting sleeve.
