International Classification:

F01L 902

US Classification:

123 9012, 123 9015, 123 9011

Abstract:

The reciprocating valve actuation and control system includes a poppet valve moveable between a first and second position; a source of pressurized hydraulic fluid; a hydraulic actuator including an actuator piston coupled to the poppet valve and reciprocating between a first and second position responsive to flow of the pressurized hydraulic fluid to the hydraulic actuator; an electrically operated valve controlling flow of the pressurized hydraulic fluid to the actuator; and an engine computer that generates electrical pulses to control the electrically operated valve. The electrically operated valve includes a linear latching motor, which includes a solenoid coil associated with a permanent magnet, wherein the coil is energized to create a central axial repelling magnetic field relative to the permanent magnet field, and to generate concentric repelling and attractive fields to produce secondary repelling and tertiary attractive forces on the permanent magnet.

US Classification:

123/090120, 123/090150

Abstract:

The reciprocating valve actuation and control system includes a poppet valve moveable between a first and second position; a source of pressurized hydraulic fluid; a hydraulic actuator including an actuator piston coupled to the poppet valve and reciprocating between a first and second position responsive to flow of the pressurized hydraulic fluid to the hydraulic actuator; an electrically operated valve controlling flow of the pressurized hydraulic fluid to the actuator; and an engine computer that generates electrical pulses to control the electrically operated valve. The electrically operated valve preferably comprises a three path rotary latched magnetic motor actuating a rotary valve portion having a housing, a rotor, and a stator receiving and supplying hydraulic fluid pressure to the rotor, which alternately directs the hydraulic fluid pressure to the valve cylinder for opening of the valve, or to return to the engine oil sump, for closing the valve. In a presently preferred embodiment, the hydraulic actuator comprises a self-contained cartridge assembly including an actuator piston with dampers for damping motion of the actuator piston, limiting the actuator stroke to assure soft seating of the actuator, and to avoid overshoot during the engine valve opening stroke and the engine valve return stroke. The electro-hydraulic valves are electrically controlled by the engine computer, which generates electrical signals carried to the electro-hydraulic valves. The engine computer typically senses conventional engine variables, and optimizes performance of the valve actuation and control system according to preestablished guidelines, with information being supplied to the engine computer by sensors. The engine computer controls all aspects of engine performance, interfaces with all of the peripheral sensors, and calculates fuel parameters, ignition timing and engine valve timing based upon prior mapping of the engine. In this manner the engine can be controlled so as to provide maximum fuel economy, minimum emissions, maximum engine torque, or a compromise between these parameters.

International Classification:

US Classification:

181/292000, 181/210000

Abstract:

An acoustic absorptive splitter consisting of two absorptive faces separated by a single on-quarter wavelength cavity support is disclosed as an equal substitute for a multi-layered splitter containing a central septum. This construction takes advantage of the reflective properties of the absorptive face sheets to support standing waves in the tuning cavities and in the duct cross modes. The utilization of these design principles permits significant silencer size and weight reduction. It also permits reduced splitter manufacturing costs by elimination of two layers of materials, difficult internal bonding and improvements in quality.

Abstract:

A Feeding tube spike set with integrated Y-port is disclosed. The preferred spike set includes a spike, a drip chamber, a y-port fitting, a stepped connector, and tubing connecting these components to one another in series. The y-port fitting further includes a body, a plug assembly and an undulating retaining member connecting the plug assembly to the body. The plug assembly further includes a plug from which a pair of tabs extend. The body also includes a flushing port formed within it; the preferred flushing port includes a plurality of ridges formed along it's bore to assist in retaining a secure seal between the inserted plug and the body.

International Classification:

US Classification:

123 9011

Abstract:

An internal combustion engine valve actuating device located directly above each cylinder which has a co-axial venturi shaped duct (20) that is removably attached with threaded capscrews (24) and sealed with an o-ring (28). The interior of the duct contains a number of inwardly facing vanes (30) that hold an electromechanical valve actuator (48) complete with an engine intake valve (50). When a pulsed electrical signal is received by the actuator, opposed electromagnetic fields are developed reciprocating the valve. A fuel injection system introduces combustible fuel into the duct at the trailing edge of the vanes. The valve actuating device may also be applied to the exhaust system, less the fuel injection, and the valve actuator may be cooled by interconnecting cavities (60) within the vanes using engine coolant or oil.

US Classification:

Abstract:

An improved insertion set is provided for transcutaneous placement of a sensor such as a glucose sensor at a selected site within the body of a patient. The insertion set comprises an insertion needle extending through a mounting base adapted for mounting onto the patient's skin. A flexible thin film sensor includes a proximal segment carried by the mounting base and adapted for electrical connection to a suitable monitor or the like, and a distal segment protruding from the mounting base with sensor electrodes thereon for transcutaneous placement. The distal segment of the sensor and a distal segment of the insertion needle are positioned within a flexible cannula which extends from the mounting base, whereby placement of the mounting base onto the patient's skin causes the insertion needle to pierce the skin for transcutaneous placement of the cannula with the sensor therein. The insertion needle can then be withdrawn from the cannula and the mounting base to leave the sensor distal segment at the selected insertion position, with the sensor electrodes being exposed to patient blood or other extracellular fluid via a window formed in the cannula. The cannula is carried by the mounting base to insure alignment of the sensor electrodes with the cannula window.
