Title: Hybrid high pressure pump for gas-liquid permeameters
Inventor: JONES STANLEY C
IPC: F04B9/105
Filed: 1988-07-18
Granted: 1991-10-29
Abstract: HYBRID HIGH PRESSURE PUMP FOR GAS LIQUID PERMEAMETERS                               ABSTRACT             A fluid pump for delivering accurate volumes of high-pressure  fluids  is  obtained  using  an intensifier to supply the majority of the motive power  required  to  displace  the  fluids.    The intensifier balances the forces between the output pressure of the displaced fluid (above a conventional drive piston) with a large diameter booster piston that is driven pneumatically by low-pressure gas.  A small  horsepower  motor  provides  needed  power  to overcome the friction of the high pressure gas pump, the differential pressure needed for the use of the pump, and to accurately control or trim the high-pressure output or rate to a precise value.  A ball screw and spur gears are used to transmit the power.       The pump is uniquely designed to reduce the stress from the motor to the components.

Abstract: Abstract A Method for Producing a Clean, Highly Conductive Surface for Mating Composite Articles A method is disclosed for providing a clean, highly conductive mating surface in a composite panel which includes an embedded aluminum wire mesh to achieve lightning and electromagnetic interference shielding.  The method includes the steps of laying a nonporous tape in a mold corresponding with the area requiring a highly conductive mating surface, laying one or more plies of aluminum mesh thereover to provide a conductive path, and then laying a nonporous barrier tape ply above the mating surface, sandwiching the metal mesh therebetween, with structural plies laid thereover.  During curing, the tapes prevent direct resin inclusion into the metal mesh.  After curing, the nonporous tape is removed to expose the clean, highly conductive mating surface.  Utilizing the above-described method substantially increases the ability to provide a clean conductive mating surface without utilizing extensive equipment or processing steps, providing enhanced EMI shielding in composite structures.

Abstract: Disclosed is an aerosol antiperspirant composition containing a silicone polymer (e.g., a silicone gum) and a volatile low-viscosity fluid in which the silicone polymer is soluble, in addition to at least a propellant and an active antiperspirant salt.  The silicone polymer is in the composition in an amount of at least 0.1% by weight based on the total weight of the composition, and is completely dissolved in the composition.  Use of the silicone polymer and the volatile low-viscosity fluid, with the polymer completely dissolved in the composition, avoids dustiness and clogging of the aerosol valve, and permits delivery of the composition at relatively low delivery rates.  Where the silicone polymer and volatile low-viscosity fluid are provided as a substantivity fluid, product bounce-back upon spraying is further reduced, product deposition is increased, and the deposited product has greater resistance to washing-off and rubbing-off.  By delivering the composition from the aerosol package at low delivery rates, product bounce-off is even further reduced, thereby further reducing dusting.

Abstract: CRANKSHAFT ASSEMBLY FOR VARIABLE STROKE ENGINE           FOR VARIABLE COMPRESSION     Abstract A crankshaft carried crankpin carries an eccentric inter-posed between the crankpin and the slider of a yoke type engine. The eccentric carries a gear to permit rotatable adjustment to to be imparted to the eccentric about the crankpin axis.  Position-ing of the eccentric includes the use of a gear train.  A gear set in the gear train has displaceable gears carried by a carrier re-sponsive to engine control means. The movable gear set serves to accelerate or decelerate the rotational speed of a pair of shaft mounted driven gears to momentarily alter their rotational speed so as to in turn rotate the eccentric mounted gear to reorientate the eccentric to the crankpin.  Such relocating of the eccentric serves to alter the piston stroke between high and low compression ranges.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention pertains to the containment of fire within ventilation ducts in a building.  To this end, a lattice consisting of highly thermally conductive material, such as expanded metal, is placed in the cross section of the ventilation duct, said lattice then conducting the heat to the walls of the ventilation duct and is thereby able to prevent or delay the passage of the flames.  Since such a lattice becomes fouled during operation of ventilation system, it must be easy to replace and clean.  For this reason, it is recommended that the particle filling, in the form of bulk expanded metal balls, be placed on a rigid midplane consisting of transverse supports or perforated plates, etc.

Abstract: METHOD AND APPARATUS FOR CONSTRUCTION OF GRAIN BINS          ABSTRACT OF THE DISCLOSURE         A circular base form is constructed from curved lengths  of  corrugated  steel  bolted  together  and  has apertured vertical brackets secured to the inside of the base form at spaced intervals around the inside of the form.   Vertical anchor pins slide within the apertures of the brackets and are driven into the ground once the circular base form is positioned correctly.   The upper edge of the base form is outwardly flanged horizontally and is successively leveled by transit or the like. As the sections are leveled, they are secured to the ground engaged anchor pins by ring bolts or the like until the entire form is leveled.   Gravel and concrete is then poured into the form, preferably with reinforcing bars, mesh or the like and leveled flush with the top flange by means  of  screening.   When set,  the lowermost wall section, the roof and then succeeding sections of the bin are assembled on the top flange of the base and are raised when each section is  completed by means  of  a crane, hoist or the like.  The lowermost wall section of the bin is provided with an out-turned horizontal base flange which engages upon caulking placed on the base wall flange and then the two flanges are bolted together thus completing the bin.
