Abstract: A tri-functional cannula combines the functions of tissue Plasminogen Activator (tPA) solution delivery, illumination and venous pressure measurement. The cannula utilizes a tapered hollow-core optical fiber having an inlet for tPA solution, an attached fiber optic splitter configured to receive illumination light from an optical source such and a LED. A window in the cannula transmits the light to and from a central retinal vein. The return light is coupled to an optical detector to measure the pressure within the vein and determine whether an occlusion has been removed.

Abstract: A sealing device for providing a seal between two relatively rotatable bearing components includes an annular ring having a radially inner and a radially outer flange. The flanges extend axially to define an annular channel. An annular wiper element is disposed in the channel so as to axially extend beyond the flanges. The annular ring is positioned axially adjacent to the rotational interface between the two bearing components so that the annular ring rotates with one bearing component and the wiper element is in surface contact with the other bearing component.

Abstract: A pneumatic tool has a one-piece metal tube forming an air motor cylinder and an associated air inlet plenum. Air passages are formed between an inner housing, molded in situ about the motor cylinder tube, and an outer housing separately molded. The inner and outer housings are both formed from a non-metal composite material which contributes to operator comfort by its light weight, thermal insulation, vibration damping, and noise suppressing properties. The tool may be assembled to provide forward exhaust, rearward exhaust, or combined forward and rearward exhaust.

Abstract: An energy efficient steam rolled grain mill includes a preheater chamber, a steam chest, a roller mill and a cooler and dryer chamber. The cooler and dryer chamber is in direct head exchange relationship with the preheater chamber.

Abstract: When tensioning a gasketed joint, the drive system applies rotational force to a threaded fastener while the monitor and control unit continuously compares a torque-related variable to a shutoff point. When the shutoff point is reached the control system reduces the drive system power, preferably to zero. After a preselected time pause the drive system is re-energized and applies another torque application until the torque-related variable again reaches the shutoff point. When the gasket is adequately compressed so that further torque applications cause insignificant increases in gasket compression, the tensioning operation is terminated. Feedback is provided by tension-related variables such as incremental angle of turn and/or incremental elapsed time of the torque application to determine when the tensioning cycle is complete.

Abstract: A roller element for a powered-roller tarnsfer system has a plurality of lubricant pressure relief areas about or in the bearing surface to increase and provide consistent rotary drive power transmitted from a powered axle to the roller.

Abstract: A rotor assembly for a vane motor has a cylindrical rotor body having front and rear shafts extending axially from the front and rear rotor faces, respectively. The rotor is rotatably supported in front and rear bearings and has radial slots extending axially along the rotor body. Radially slidable vanes are provided in each radial slot, and a rear end plate is fixed to the rear face of the rotor body so as to rotate with the rotor and to completely close the slots on the rear face of the rotor. A spacer is provided at the front face of the rotor body to provide clearance for a front end plate which radially circumscribes the front spacer so as to close the radial slots at the front face while still permitting relative rotation between the spacer and the front end plate. The spacer may be integrally formed with the shaft or may be of a separate piece fitting to the shaft.

Abstract: A radical flow mechanism is provided having a symmetric housing assembly defining a hollow rotor chamber. A symmetric shaft and rotor assembly is supported for rotation in the rotor chamber. A plurality of radial flow paths are defined by the rotor and the housing assembly. The assembled module may be powered by a pressurized motive fluid that flows radially inward to rotate the rotor. Alternatively, the rotor may be driven by an external power source so that a working fluid increases in potential energy as it moves centrifugally outward. The assembled module is symmetric about the rotor member so that the rotor can be orientated for either direction of rotation and so that power takeoff or power connection can be to either side of the module. Also, the module is constructed so that the seals are located at an interface having a low pressure differential and the bearings are located adjacent an area encouraging heat dissipation.

Abstract: A tilt valve cartridge for a pneumatic mechanism has a cylindrical housing having two open ends, an annular valve seat secured in one open end, a valve member in tiltable contact with the annular seat and having a valve stem which extends through the valve seat and protrudes from the end of the cylinder, a spring to hold the valve member in a normally closed relationship with the valve seat, a sealing element secured to the cylindrical housing on its exterior surface so as to seal the interface between the cartridge and the mechanism, and retention feature to capture the valve member and valve biasing spring within the cylindrical cartridge. The modular cartridge feature simplifies installation and replacement of the valve in the inlet air passage of the pneumatic mechanism.

Abstract: The powered ratchet wrench 10 is constructed of several components. A throttle lever 20 controls the air flow to a rotary air motor 30. The rotary output of the motor is transmitted to the hammer assembly 40 of an impact clutch mechanism. A spring 50 biases an anvil shaft 60 into association with the hammer assembly 40. The anvil can be directly driven by the motor through the hammer assembly or can be driven intermittently by a series of rotational impacts from the hammer assembly. The rotation of the anvil shaft causes the reversible ratchet mechanism 70 to rotate in the desired direction, thus tightening or removing a threaded fastener. Only a small reaction force is transmitted by the tool to the operator once the fastener is tightened.

Abstract: A rotary drum filter has a plurality of longitudinally extending division grids mounted about the outer circumference of a drum. A plurality of corrugated sheets are provided, with the leading and trailing edges of each sheet mounted to circumferentially adjacent pairs of division grids to define filtrate compartments. An equivalent number of perforated filter plates are also provided. Each filter plate is attached to the top of a corrugated sheet and has a leading edge that is set back from the leading edge of the attached sheet. A seal member is positioned at the leading edge of each corrugated sheet and has a first leg extending between the filter plate and the corrugated sheet. The seal member further includes a second leg which abuts the leading edge of the corrugated sheet so as to block the open ends at the leading edge of the corrugated sheets.

The piston-cylinder assembly is hydraulically actuated.

Abstract: A Rankine cycle turbine drives an electric generator and a feed pump, all on a single shaft, and all enclosed within a hermetically sealed case. The shaft is vertically oriented with the turbine exhaust directed downward and the shaft is supported on hydrodynamic fluid film bearings using the process fluid as lubricant and coolant. The selection of process fluid, type of turbine, operating speed, system power rating, and cycle state points are uniquely coordinated to achieve high turbine efficiency at the temperature levels imposed by the recovery of waste heat from the more prevalent industrial processes.
