Abstract: VELOCITY SENSITIVE SEAT DAMPER SYSTEM                 ABSTRACT OF THE DISCLOSURE    A seat suspension system, which includes a height adjustment valve for positioning a seat at a desired height in response to manual positioning of a height adjustment lever by controlling the amount of hydraulic fluid supplied to a cylinder having a piston therein coupled to the seat, provides damping of vertical motion of the seat by an accumulator coupled to the cylinder via a conduit so as to receive the hydraulic fluid from the cylinder and two different valves disposed in the conduit.  A manually adjustable flow control valve has an adjustable orifice within the conduit for providing the seat with a nominal amount of damping.  The damping of the suspension system is increased be-yond the nominal amount in response to seat velocity in a down-ward direction by the second valve which responds to the pressure of hydraulic fluid flowing from the cylinder to the accumulator so as to restrict the flow of the fluid by an amount dependent upon the fluid pressure and thereby the rate of change of downward movement of the seat.  At the same time the second valve is generally unresponsive to the pressure of fluid flowing in an opposite direction from the accumulator to the cylinder so as to be unidirectional in nature.

Abstract: ABSTRACT OF THE INVENTION A dual chamber pacing lead requiring but a single transvenous pass for implantation.  The ventricular electrode has tines for sustaining acute and chronic fixation.  The ventricular electrode is coupled to a first conductor which is space wound having an insulation sheath.  The proximal end of the first space wound coil protrudes slideably from a first connector pin of a bifurcated connector assembly.  An optional stylet may be inserted into the first space wound coil to assist in ventricular placement.  A second space wound coil is slideably located over the first space wound coil.  The second space wound coil serves as a support means rather than a conductor.  The proximal end of the sec-ond space wound coil is fixedly attached to the connector assembly.  The first space wound coil protrudes near the distal end of the second space wound coil. A third space wound coil having an insulating sheath serves as a conductor having the distal end attached to the tined atrial electrode and the proximal end coupled to a second pin of the bifurcated cable.  The distal end of the third space wound coil is located coaxially within the second space wound coil. A stylet straightens the distal end of the third space wound coil which assumes a "J" shape upon removal of the stylet.  An outer sheath encloses the second and third space wound coils from the bifurcated connector to the atrial elec-trode.

Abstract: ADDITION OF MgC12 TO CATALYST                       Abstract A process for economically converting carbo-metallic oils to lighter products.  The carbo-metallic oils contain 650°F and material which is characterized by a carbon resi-due on pyrolysis of at least about 1 and a Nickel Equiva-lents of heavy metals content of at least about 4 parts per million.  This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900 to about 1400°F, and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50%. to about 90%. while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and lay-ins down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight.  The spent, coke-laden cata-lyst from the stream of hydrocarbons formed by vaporized feed and resultant cracking products is separated and regenerated in one or more regeneration beds in one or more regeneration zones by burning the coke on the spent catalyst with oxygen.          The bed density is in the range of about 25 to about 50 pounds per cubic foot and the bed or beds are sustained by fluidization gas containing combustion-supporting gas having a linear velocity in the range of about 0.2 to about 4 feet per second.  MgC12 is  added to the catalyst and is converted to MgO, which reduces sulfur oxide emissions, and a chlorine component, which reduces the CO2/CO ratio, thereby reducing the heat output of the regenerator.  The catalyst particles are retained in the regeneration zone or zones in contact with the combustion-supporting gas for an average total residence time in said zone or zones of about 5 to about 30 minutes to reduce the level of carbon on the catalyst to about 0.25% by weight or less.  The regenerated catalyst is recycled to the reactor and contacted with fresh carbo-metallic oil.
