Title: Method and apparatus for gravel packing of wells
Inventor: MCQUEEN ROBERT W
IPC: E21B41/00
Filed: 1991-10-15
Abstract: ABSTRACT       A well penetrator has a housing moveable down a well casing with a radially moveable punch being supported in the housing for movement between retracted and extended positions; a fluid jet is discharged from the outer end of the punch with liquid for the jet coming from a tube fixedly positioned at one end in the housing and held in slightly bowed condition when the punch is retracted to permit movement of the punch to its extended position from its retracted condition without the creation of excessive force on this metal tube.   The jet creates a bulbous drumstick shaped cavity in the earth which is packed with a gravel slurry which hardens and cannot move into the casing due to the bulbous shape of the hardened slurry mass.   Similar procedures are employed using a hose or lance with a nozzle at its outer end; one nozzle embodiment includes radial jets activated to transversely enlarge the cavity at a location spaced from the casing.

Title: Extruder for Poorly Miscible Extrudates
Inventor: CAPELLE GERD
IPC: B29C48/50
Filed: 1991-12-13
Abstract: An extruder for poorly miscible extrudates is presented,  in which the pin-lined barrel section and transfer mixing section, known per se and until now only used individually,  are used together in an extruder.          Restricting pins arranged in the transfer mixing section in the region of the greatest barrel channel volume permit universal use of the extruder with respect to the extrudate.  The combination of the two mixing systems allows in a surprising way an increase in the material throughput of 60% to 100% with the mixing quality remain-ing the same and a halving of the drive torque. Due to a constant number of channels of the barrel channels and screw channels, the number of barrel flights and screw flights  remains  independent  of  the  channel  cross-sectional area of barrel and screw. A helical barrel groove in the feed zone of the extruder barrel addi-tionally improves the mixing quality of the extrudate and the output of the extruder.

Title: Determining the diuretic potency of candidate drugs
Inventor: HARRIS H WILLIAM
IPC: G01N33/74
Filed: 1990-12-31
Abstract: A method for determining the diuretic potency of candidate drugs as inhibitors of ADH-elicited water channels is disclosed. In a preferred embodiment, such diuretic potency of candidate drugs is determined by suspending vesicles containing ADH water channels in an aqueous suspending medium, incorporating the candidate into the suspension, rapidly changing the pH of the suspending medium and thereafter detecting the proton permeability of the water channels. The proton permeability in the presence of the candidate drug can then be compared to the proton permeability of water channels under similar conditions without the presence of the candidate drug to determine the diuretic potency of the candidate drug to inhibit ADH-elicited water channels.

Title: Fatigue resistant eutectic solder
Inventor: WONG BOON
IPC: B23K35/26
Filed: 1992-09-17
Abstract: The fatigue resistance of lead-tin eutectic solder is increased by doping the solder with less than about 1.0 weight % of a dopant selected from cadmium, indium and  antimony.    The  doped  eutectic  solder  exhibits increased  resistance  to  thermally  or   mechanically induced cyclic stress and strain. As a result,  the fatigue resistance of the solder joint is increased. Combination of dopants, such as indium and cadmium, in combined  amounts  of  less  than  0.5  weight  %  are especially   effective   in   increasing  the   fatigue resistance of the lead-tin eutectic solder.

Abstract: The method and apparatus of this invention transform naturally occurring or synthetic waxes into a state characterized by the fact that when the waxes solidify, they do so in forms different from those forms into which they would solidify except for the transformation. The transformation is achieved by subjecting the waxes to force. As examples of apparatuses which can supply the force to effect the transformation, a piston apparatus and an ultrasonic apparatus are disclosed. The triglyceride waxes are one type of wax which may be transformed by the method and apparatus of this invention. Transformed triglyceride waxes form superior shells when the waxes are used in an encapsulation process.

Title: Washing machine
Inventor: HOSSFIELD ROBIN C
IPC: D06F37/24
Filed: 1993-05-10
Abstract: Abstract of the Disclosure A washing machine having the cabinet decoupled from the suspension system in order to eliminate undesirable resonance mode walking conditions.  The cabinet is frictionally attached to the washer supporting feet. With this arrangement, the effect of the cabinet on the washer/floor natural frequency is eliminated, thereby increasing such natural frequency above the spin speed of the washer.  In this way, walking typically occurring at the natural frequency (i.e. when the spin speed matches the natural frequency of the washer and floor system) is prevented.  This arrangement further provides decreased cabinet vibration and noise during operation at typical spin speeds.
