Title: A flotation process for the formation of metal matrix composite bodies
Inventor: DWIVEDI RATNESH K
IPC: C04B41/51
Filed: 1989-10-13
Abstract: The present invention relates to a novel method for forming metal matrix composite bodies. Particularly, a permeable mass of filler material is formed into a preform. The preform material can then be placed onto the surface of or into a matrix metal alloy, whereupon the matrix metal alloy spontaneously infiltrates the preform. After substantial complete infiltration of the preform, the preform begins to at least partially sink into the matrix metal alloy supply. The matrix metal Which has infiltrated the preform is then allowed to cool, thus forming a metal matrix composite body.

Title: Electro-pneumatic actuator
Inventor: RICHESON WILLIAM E JR
IPC: F01L9/20
Filed: 1990-01-03
Abstract: PHA. 40-558                                          08-08-1989 ABSTRACT:          ELECTRO-PNEUMATIC ACTUATOR     A bistable electronically controlled pneumatically powered transducer for use, for example, as a valve mechanism actuator in an internal combustion engine is disclosed. The transducer has a piston which is coupled to an engine valve, for example. The piston is powered by a pneumatic source and is held in each of its extreme positions, and air control valves are held in their closed positions by pressurized air and/or permanent magnet latching arrangements and the control valves are released therefrom to supply air to the piston, and the piston is released therefrom to be pneumatically driven to the other extreme position by an electromagnetic neutralization of the permanent magnet field. The piston forms a part of the magnetic latching circuit and that magnetic circuit also includes a radially slotted ferromagnetic member to both complete the magnetic circuit and provide a good air communication path from a high pressure air inlet to the control valve. A pair of auxiliary pistons movable with the piston compress air to a pressure above the pressure of the pneumatic source for aiding reclosure of the control valves as well as aiding maintenance of those control valves in their closed positions thereby reducing the size and cost of the latching permanent magnets.

Title: No bounce dart
Inventor: BOTTELSEN WALTER E
IPC: F42B6/00
Filed: 1990-02-09
Abstract: NO BOUNCE DART            Abstract of the Invention A no bounce dart comprising a barrel having an axial cavity in its forward end.  A point is mounted at the forward end of the barrel with the rearward portion of the point being slidably disposed in the barrel cavity.  The point is afforded slidable movement between an extended position wherein the rearward end of the point is spaced apart from the bottom wall of the barrel cavity and a hammering position wherein the rearward end of the point contacts the bottom wall of the barrel cavity.   An O-ring is mounted in the cavity in surrounding relation  to  the  point  to  continuously  frictionally  impede movement of the point from its extended position to its hammering position.  The time delay in the hammering action of the dart provided by the O-ring avoids bounce backs.

Title: Slurry mixing apparatus
Inventor: BERRYMAN LESLIE N
IPC: B01F7/16
Filed: 1990-04-17
Abstract: Abstract Of The Disclosure A mixing apparatus is provided for mixing slurries, par-ticularly high density, high viscosity fracturing fluid slurries containing a large proportion of proppant material.          A mixing tub has a generally round horizontal cross-sectional shape.  A relatively large, low-speed rotating agitator is utilized to mix the slurry.  The design of the agitator is such that a radially inwardly rolling toroidal shaped slurry flow zone is created adjacent the upper sur-face of the slurry within the tub.  A stream of clean frac-turing fluid is introduced into the tub near the center of the toroidal shaped flow zone.  Dry proppant material is introduced into the tub and carried by the radially inwardly rolling flow into contact with the clean fracturing fluid.          Foraminous baffles, preferably constructed from expanded metal sheets, are radially oriented within the tub to reduce rotational motion of the slurry within the tub without causing dropout of proppant from the slurry.  A double suc-tion vertical sump pump is utilized to pump the slurry from the tub.

Title: Inflation valve with actuating lever interlock
Inventor: KELSALL GERRARD
IPC: B63C9/18
Filed: 1990-05-29
Abstract: INFLATION VALVE WITH ACTUATING LEVER INTERLOCK                   ABSTRACT An inflator according to the present invention com-prises a valve body having a replaceable pressure cartridge that is pierced by a piercing pin is operated by an actuat-ing lever to inflate an attached object.  The valve body is mounted in a protective housing, and a lanyard carried by the actuating lever extends through an opening in the hous-ing.  The lanyard carries an indicia member that emerges from the housing when the handle is pulled to actuate the valve to provide a visible reminder that the cartridge has been discharged and needs replacing.   The piercing pin slides in a sleeve slidable in a piercing pin chamber.  A spring biases the piercing pin into engagement with the actuating lever. The lever is pivotable from stored to actuated positions to force the pin to pierce the pressure cartridge.  An interlock comprising interengageable locking surfaces on the actuator lever and on the pin prevent movement of the lever from actuated position unless the discharged cartridge has been removed.  Once the cartridge has been removed, a lockout pin projects into the cartridge chamber to obstruct the insertion of a fresh cartridge until the actuator lever retracts the pin upon return to its stored position.  The actuator lever is retained in its stored position by a spring mounted to the actuator lever which releasably engages the housing, and the lanyard is looped through the spring.
