An enhanced uplink user equipment is in soft handover. A radio network controller selects a primary Node-B out of a plurality of Node-Bs supporting the soft handover. The radio network controller receiving successfully received enhanced uplink data packets from the plurality of Node-Bs. The radio network controller reordered the successfully received enhanced uplink data packets for in-sequence deliver. The primary Node-B sends specified scheduling information to the user equipment that the other Node-Bs does not transmit. At least the primary Node-B transmits acknowledgements and negative acknowledgements to the user equipment.

According to one embodiment, an information viewing system includes an ontology viewing engine coupled to a client and a knowledge store that stores records organized according to a domain ontology. The ontology viewing engine receives requests for records from the client, filters the domain ontology according to a display ontology, generates a graphical user interface (GUI) according to the display ontology including the requested records, and transmits the GUI to the client through an application programming interface of the GUI.

The invention includes apparatus and method for lubricating and cooling a workpiece, dies or ironing rings, and punch at the interface between the workpiece and such dies or ironing rings and punch in forming a workpiece into a hollow closed end cylindrical article.A lubricant liquid phase is injected into a coolant liquid phase to form a "dispersion" prior to application to the metal-tool interface. Providing the lubricant as a dispersion in the coolant liquid phase rather than as an emulsion provides several advantages. The quantity of lubricant and the time of lubricant injection can be varied to control lubricity and, thus, friction. The invention makes it possible to achieve differential friction in the ironing process by having higher lubricity on the ironing die (low friction) and lower lubricity on the punch surface (high friction). Lubricities and cooling are controllable for the specific metal forming process employed to produce closed end hollow body containers. After applicaiton, the lubricant and coolant are separated, the lubricant filtered to remove debris, stored, and then reinjected to provide lubrication for the process.

A novel and improved method of deforming elongated hollow members so as to maintain uniform cross-sectional profile, uniform section thickness reduction, and minimal springback characteristics which includes superimposing in the forming process an internal fluid pressure support for the hollow member which imposes a circumferential tension thereon, a longitudinal tension which plastically elongates the member, and a transverse bending load which plastically bends the member.

In a gas turbine engine of the type wherein the fuel is injected through apray injection nozzle into a combustion chamber, the improvement is a method and apparatus for modifying the characteristics of the fuel spray from the fuel injection nozzle so that fuels of higher aromatic content can be efficiently used in the engine. An electrode is disposed within the combustion chamber to provide a high strength electrostatic field in the vicinity of the injection nozzle so that the fuel spray from the nozzle becomes charged as it leaves the nozzle. The strength of the electric field is adjusted to provide a spray characteristic which produces optimum engine performance as determined by measuring an operating parameter of the engine such as the temperature of the gases exiting from the combustion chamber. An electrode structure is disclosed in which a central conductor is covered by two concentric layers of high density insulating material except at an exposed end surface which faces the injection nozzle and is disposed on its longitudinal axis. An annular passage is provided between the two layers of insulating material through which passage an inert gas is directed to provide a protective layer to insulate the exposed conductor from the flame.

A lever operated switch actuator has a resilient lever secured at its lower end to a bracket and having a control knob at its upper end. The bracket is secured to a supporting surface. A pair of switches having plungers are secured to the bracket on opposite sides of the lever. A lever stop member is secured to the bracket and has stops positioned on opposite sides of the lever and immediately above the switch plungers. The stops of the lever stop member are adjustable with respect to the switch plungers. The lever can be manually grasped at the control knob and deflected forwardly or rearwardly to depress a plunger which activates a switch. A lever stop contacts the lever once a plunger is depressed.

A direction control valve for controlling a reversible hydraulic actuator includes a valve body in which a pair of valve stems and a pair of float control pistons, respectively axially aligned with the valve stems, are reciprocally mounted. To establish a float condition in the actuator, the pair of valve stems are simultaneously shifted to respective active positions by engagement of the pair of float-control pistons to which pressure fluid is routed upon selective energization of a solenoid-operated valve by manually closing a first normally open switch. A second normally open switch is connected in parallel with the first switch and is closed by a switch-control piston mounted in the valve body between and in fluid communication with the float-control pistons and shiftable concurrent therewith whereby the manually operable switch may be released without effecting de-energization of the solenoid-operated valve. A control rod is rockably mounted in the valve body for selective movement to opposite sides of a neutral position for respectively initiating independent shifting of the pair of valve stems to their active positions for respectively effecting extend and retract conditions in the actuator. A cam is fixed to the control rod and is operable, when the control valve is in its float-effecting condition and the control rod is moved from its neutral position, to move the switch-control piston to release the second switch and de-energize the solenoid-operated valve whereby the control valve is released from its float effecting condition.

A flexible thin film battery including a film layer and a porous cathode deposited on a portion of a film and a porous anode deposited on a portion of the film, with an electrolyte and separator layer positioned between the porous anode and the porous cathode. The electrolyte is preferably dried so the battery is activated when liquid contacts the electrolyte and separator layer. In a preferred embodiment, water swellable particles are included in the cell. The film layers are least partially sealed around the edges, confining the anode, cathode, and electrolyte and separator layer. The method of producing such a battery preferably includes printing various inks in a pattern on a polymeric film.

A hinged vertical exhaust pipe is provided to allow easy adjustment of the height of the exhaust pipe. The upper and lower sections of the exhaust pipe are hinged together by a stiff joint, e.g., a spring-loaded hinged friction joint, and are positioned in line with one another with a slight gap between them. The lower section is double walled, and the inner wall extends somewhat up into the upper section. The upper section is single walled, with its wall aligned with the outer wall of the lower section. Air is drawn into the space between the inner and outer walls at the base of the lower section and also at a gap at the joint between the upper and lower sections. This air is drawn in both due to the aspiration caused by the higher speed exhaust flow through the inner exhaust pipe, and due to thermal rising of heated air. The space between the inner wall of the lower section and the wall of the upper section acts as a venturi, directing the air in a uniform fashion up into the upper section of the exhaust pipe. This cools the pipe and minimizes blow back at the joint between the upper and lower sections of the pipe.
