Title: Internally insulated extrusion die
Inventor: WOLFE JOHN R JR
IPC: B29C48/06
Filed: 1987-05-21
Granted: 1991-04-23
Abstract: INTERNALLY INSULATED EXTRUSION DIE                 (Abstract of the Disclosure) A die assembly for plastic pelletizing apparatus of the type including a cooling bath into which the plastic is extruded.  The die assembly includes a heated main body having first and second oppositely disposed exterior faces connected by a plurality of relatively small extrusion passageways.  A layer of thermal insulation material overlies the second face, and a cover member having an outer surface adapted to be exposed to the cooling bath is positioned over the thermal insulation material and joined to the main body.  Wear resistant insert members formed from a material having a higher coefficient of thermal conductivity than the material from which the cover member is made extend from the outer surface of the cover member through the layer of insulation into the main body.  Extrusion outlet orifices are formed through the insert members and define continuations of the extrusion passageways of the main body.  The relationship between the inserts, the cover, the insulation, and the main body produces an increased heat flow from the main body to the outer die face in confined areas about the orifices.  This heat flow advantageously reduces the possibility of freeze-off and plugging of the orifices due to premature solidification of the extruded plastic.

Granted: 1994-04-12
Abstract: ABSTRACT OF THE INVENTION         A process and apparatus are provided to increase the retarding horsepower of a compression release engine retarder driven from the exhaust valve pushtube or the fuel injector pushtube.  The mechanism includes a plenum communicating with the exhaust valve slave piston and the master piston driven by a remote exhaust valve pushtube or the fuel injector pushtube.  A trigger check valve is located between the master piston and exhaust valve slave piston so that the initial motion of the master piston delivers energy to the plenum.  At a predetermined point in the travel of the master piston, the trigger check valve is opened by the master piston to permit the delivery of the energy stored in the plenum to the valve piston.  Additional pumping capability is pro-vided by a second master piston while a control check valve communicating with the second master piston limits the intake of hydraulic fluid into the system after working pressures have been attained to that hydraulic fluid which may leak from the system.  The process includes cyclically storing energy in the plenum, releasing the stored energy from the plenum at a predetermined point in the travel of the master piston driven by the exhaust or fuel injector push-tube and directing the stored energy to the slave piston whereby the exhaust valve is opened rapidly at a predetermined time.

Inventor: PODSOBINSKI PAUL A
IPC: B25B23/145
Filed: 1988-01-08
Granted: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE The air tool of the present invention includes a torque shut-off valve totally enclosed within and substantially coaxial with the body housing of the tool. The torque shut-off valve includes a valve member reciprocally sliding in and guided by a bore and counterbore in the valve body. The valve member is biased by a reset spring to its open position before the tool cycle is initiated. In operation, the valve member is axially biased toward its open position by supply line air pressure in an air inlet chamber in conjunction with controlled reduced air pressure in an associated compartment and is axially biased toward the closed position by motor inlet pressure. A preselected motor back pressure resulting from achieving the desired tool torque operates to overcome the opposing pressure to close the valve member to block air flow to the motor.

Abstract: ABSTRACT OF THE DISCLOSURE   A solid state imager has a substrate with a plurality of light receiving areas, with vertical registers to transfer charges accumulated in the light receiving areas either through the vertical registers to a horizontal register section and an output terminal, or to a drain region.  The transfer is accomplished by use of externally supplied driving pulses.  By use of a high-speed normal-transfer operation, charges which are trapped by potential barriers and/or potential dips, and which would normally appear as noise in the form of black spots or bright spots, can be eliminated prior to the read out if the charge signals via the vertical registers and the horizontal register, whereby the output signal is produced free of such noise.
