Abstract: Abstract - Centering device of  this  invention  is  particu-larly  useful  when  mounted on casing which must be run into wellbores to assure uniform clearance  between  the  wellbore and  the  casing.   The  outstanding  difference between this centering device and other non-welded  centering  devices  is that this unit does not require any bending or deformation to any  of  its  elements  during  the  assembly  or disassembly procedure,   yet   incorporates   stand-off   characteristics necessary  during  the  utilization  of  the unit within the wellbore.  The design  and  construction  of  this  invention allows  for  the secure attaching of the elements to form the centering device through the use of an independent  retaining ring which is unique to this invention.

Abstract: ABSTRACT           A gaseous fuel delivery system for a gasoline engine having a gaseous fuel delivery valve means comprising an idle fuel delivery valve and an acceleration fuel delivery valve.  Means responsive to air flow through the carburetor throat controls operation of the idle fuel delivery valve.  Means responsive to intake manifold vacuum controls operation of the acceleration fuel delivery valve.  Electrically operable alternately open idle and acceleration solenoid valves are interposed in separate delivery conduits from the idle and acceleration fuel delivery valves.          Means responsive to the opening of the acceleration fuel delivery valve opens the acceleration solenoid valve and closes the idle solenoid valve, reversing the respective valve positions on closing of the acceleration fuel delivery valve.  An idle switch responsive to idle position of the throttle prevents opening of the idle solenoid valve except when the throttle is in the idle position. The engine carburetor is arranged such that no gasoline is delivered for idle operation.          Idle needle valves are closed, or eliminated.  Transition slots are sized to be operational only as the throttle moves from the idle position and supply no fuel when the throttle is at idle.

Abstract: ABSTRACT OF THE DISCLOSURE    A pressure swing adsorption process is provided for the direct production from ambient air of a moderately enriched oxygen product gas.  The production of a product gas having an oxygen concentration of 23 to 30% is effected by a three step cycle wherein (1) the feed air is charged to a bed of nitrogen selective adsorbent until the bed is brought from atmospheric pressure to a pressure in the range of up to 4 atmospheres, (2) reducing the bed pressure to an intermediate level by withdrawal of oxygen enriched product gas therefrom and (3) finally venting the bed to restore atmospheric pressure.  By an alternative mode including a fourth step of purging the bed following the venting step, a product of 23 to 45% oxygen concentration is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of preventing the precipitation of proteins, such as hormone preparations, within drug delivery systems that depend on the fluidity of the infusate for proper function while extending and maintaining the biological activity of the protein during its period of storage in the drug delivery system.  A polyol, such as glycerol, is mixed with the protein solution prior to the introduction of the solution into the drug delivery system.  The polyol is added in amount between about 10 and 90% by volume sufficient to prevent precipitation of the protein dur-ing long-term storage in the drug delivery device.  A physiologi-cally compatible buffer system in concentration between about 1 mMolar and 1000 mMolar sufficient to maintain the pH of the solu-tion within about one unit of the optimum pH of the protein is added to maintain the bioactivity of the protein during its extended period of storage.  According to one form of usage, the protein-polyol-buffer solution is injected to the pressurized drug storage reservoir of an implanted infusion pump by injection through the patient's skin.  As the solution is discharged from the delivery device by the constant pressure exerted upon the storage chamber, its low rate of flow is controlled by a restricted fluid passage.  The solution is conveyed to an infu-sion site and diluted by the blood stream.

Abstract: ABSTRACT     A capacitive pressure transducer whose diaphragm is formed of single crystal, highly doped silicon by etching in opposite sides the recesses which define the deflecting region of the diaphragm,  This deflecting region serves as one electrode of the transducer.  Two support plates of silicon are anodically bonded to opposite sides of the diaphragm along its periphery using thin layers of borosilicate glass to form with the etched recesses pressure receiving cavities.          These Thin layers of borosilicate glass are interposed between the diaphragm and a support plate, and extend over the entire surface of the support plate facing the diaphragm to provide for electrical isolation as well as the bonding between the diaphragm and the support plates.  These layers of glass are made as thin as possible consistent with the need to maintain the stray capacitance below a certain value.     The transducer is mounted to a pressure receiving assembly by using a silicon stub having a passage for communicating one pressure to be measured to the transducer.  The stub is joined at one end to the transducer by anodic bonding using a thin layer of borosilicate glass.          A weldable tube is attached to the stub.  This tube is long with respect to the stub and has a reduced diameter at one end which fits into the passage of the stub,  The reduced diameter is kept at a minimum.  The tube is welded to the pressure receiving body at its end to provide mechanical isolation for the transducer.
