Abstract: BALLOON CATHETER            ABSTRACT        Disclosed is an embolectomy catheter for insertion in a vascular passage, the catheter adapted to be pulled through the vascular passage to remove material therefrom.  The catheter comprises an elongated support member having a diameter sized to fit within the body passage and a distal end, the support member including an elongated coil spring and an extensible tubular sheath disposed around the coil spring. A strain relief collar has a first end securely affixed to the distal end of the support member and has a second end, the strain relief collar being movable between a rest position and an extended position.  An inflatable balloon sized to fit within the body passage has an end securely affixed to the strain relief collar, the balloon having a lower inflation pressure than the strain relief collar such that for inflation pressures less than a first value the balloon inflates but the strain relief collar remains in its rest position, and that for inflation pressures greater than a second value, no less than the first value, the strain relief collar moves to its extended position in order to receive fluid from the balloon to increase the length and reduce the diameter of the balloon.

Abstract: ABSTRACT OF TEE DISCLOSURE                 Treatment of viscous crude oils Asphaltenes and/or wax and/or water are removed from crude oil by contacting the crude oil with an organic solvent to dissolve the crude oil and precipitate asphaltenes and/or wax and separate the oil and water. Solvent is then separated from the deasphalted and/or dewaxed and/or dehydrated crude oil.    Removing asphaltenes, wax and/or water reduces the viscosity of the crude oil and it can then be transported, eg by pumping through a pipeline, with less expenditure of energy.

Abstract: ABSTRACT OF THE DISCLOSURE    A control system for a refrigeration heat pump having an outdoor coil through which air is blown by a fan for extracting heat from outdoor air with means to defrost the coil periodically has a differential pressure responsive means responding to the differential air pressure across the outdoor coil.  A time control means periodically operates the heat pump for a time controlled operation for predetermined time period (such as 90 minutes of elapsed operating time) and measures and stores the value of the differential pressure across the coil at the end of the time period in memory.  A control means controls the heat pump between the periodically time controlled operations for normal operations for a total elapsed time operation in a pressure controlled operation until the pressure differential as previously stored occurs at which time a defrost cycle is initiated. Periodically a time controlled operation is initiated to update the pressure stored in toe memory.

Abstract: HYDROCARBON GAS SEPARATION            ABSTRACT OF THE DISCLOSURE           A cryogenic process for separating methane from ethane and heavier hydrocarbons in which a high pressure gas feed is divided into two gas streams.  The gas is cooled either before or after it is divided and this step may include some condensation in which case the condensate is separated from the gas.  One of the divided gas streams is expanded through a work expansion machine down to the pressure of the fractionation column.  Any separated condensate is also expanded to the column pressure.  The second divided gas stream is further cooled by heat exchange and then expanded down to an intermediate pressure whereby a portion is condensed.  This condensate is separated from the remaining gas and then expanded to the column pressure.  The remaining gas is further cooled and expanded and fed to the column as the top feed.

Abstract: ABSTRACT       The rivet comprises a tubular body having a shank having a rivet head at one end and an end portion of which is tapered externally and internally towards the other (tail) end.  A stem, disposed in a bore of the body, has a stem-tail which projects from the head end and breaks off when the rivet is set, a plug in the bore, and a ter-minal head abutting the tail-end.  The diameter of the plug is reduced progressively and stepwise towards the terminal head, providing an abutment and an annular groove between the terminal head and the abutment.  Material of the end portion extends into the groove to maintain the body and stem assembled, and enters further into the groove during setting of the rivet.  The rivet is set by pulling the stem tail while supporting the body, causing the shank to collapse into a bulge which provides a blind head.  The external tapering of the portion promotes bulg-ing at a lower applied force than would otherwise be required.  Loss of the plug is prevented by the abutting of body material in the groove against the abutment, assisted by friction between the body and splines on the plug which embed in a locking region of the body during setting.

Abstract: Abstract of the Disclosure A coherent frequency, velocity responsive elec-tronic surveillance system detects the motion of a trans-ponder relative to two receiving antennas on opposite ends of a surveillance zone positioned at the exit of a retail store.  Motion in opposite directions relative to the two antennas indicates that the transponder is within the surveillance zone.  As a means of reducing false alarms, motion of a transponder proximate to, but outside the zone is distinguished from motion inside the zone because motion outside the zone is in the same direction relative to both antennas.  False alarms are reduced even further by re-quiring detection of motion through a selected distance before indicating an alarm.

Abstract: Abstract of the Disclosure This invention is directed to a process and a novel composition for forming a conductive thermoset material which comprises admixing (a)  particles of a polymeric material crosslinked to at least its gel point and swellable at its plasticization temperature, (b)  at least one liquid reactive plasticizer for (a) (c)  optionally and preferably a curing agent for the reactive plasticizer, and (d)  heat or electrically conductive particles, and thereafter heating the admixture for a time sufficient to flux and cure same to obtain a conductive thermoset material. The crosslinking of the thermoplastic polymer can optionally be carried out in a solvent for the polymer.  Upon heating, above the plasticization temperature, the liquid reactive plasticizer plasticizes the lightly crosslinked polymer particles.  This results in the swelling of the polymer particle, forcing the conductive filler to pack tightly and orderly, thereby increasing the conductivity of the plasticized conductive thermoset after curing.
