Abstract: ABSTRACT OF THE DISCLOSURE      PROCESS FOR ISOMERIZING ALKYLAROMATICS      A process is disclosed for producing a selected C8 alkylaromatic isomer from a feedstock containing a less than equilibrium concentration of the selected isomer and a low C8 naphthenes concentration, in which the feedstock is first contacted with a platinum-halogen catalyst at low temperature isomerization conditions to form an intermediate reaction mixture containing a substantial amount of C8 naphthenes and a partially isomerized mixture of C8 alkylaromatics; the inter-mediate mixture is then contacted with another platinum-halogen catalyst at higher temperature dehydrogenation conditions to form a final product mixture with a very low naphthenes content and a substantially equilibrium concentration of the selected isomer; and the selected xylene isomer is recovered from the final product mixture.

Abstract: ABSTRACT    A method and apparatus is disclosed wherein simultane-ous logs may be made at different lateral distances through a formation from a borehole by guard electrode systems located on a sonde which is lowered into the borehole by a logging cable.  A single oscillator controls the frequency of two formation currents flowing through the formation at the desired different lateral depths from the borehole.          The armor of the logging cable acts as the current return for one of the guard electrode systems, and a cable elec-trode in a cable electrode assembly immediately above the logging sonde acts as the current return for the second guard electrode system.  Two embodiments are also disclosed for measuring reference voltages between electrodes in the cable electrode assembly and the guard electrode systems.

Abstract: ABSTRACT OF THE DISCLOSURE          A picture viewer is disclosed for the alternate exposure of individual rectangular sheets from a pile of sheets.  It comprises an enclosure having a viewing window and a compartment with sufficient depth to accommodate such a pile, one end of the compartment being disposed at the window to display a sheet through the window, another side of the compartment having an access opening, and means permitting separation of one sheet from one end of the pile and adding it to the pile at the other end thereof.  Such means includes:  pile support means opposite the viewing window and pile suppression means adjacent the window, a separator bar extending parallel to congruent edges of the sheets in the pile and having a first edge opposite the window and a second edge adjacent thereto, the separator edges being spaced from each other such that removal and insertion slots are defined between respective separator edges and compartment walls confining the access opening.    The pile support means and the pile suppression means are spaced from each other by a distance exceeding the distance by which the separator edges are spaced from each other, the separator bar further having a first oblique face confronting the congruent sheet edges and a second oblique face opposite the first face.  Both of the separator faces extend between the first and the second separator edge, whereby a sheet to be separated from the pile and thrust edgewise against the separator is deflected away from the pile permitting it to be fed through one of the slots and whereby a sheet when added to the pile after being fed through one of the slots will be retained by the separator bar at its edge adjacent the latter.

Abstract: ABSTRACT       An improved shim arrangement for adjusting the camber of a wheel in a steerable driving axle assembly, such as a front axle assembly of a four wheel drive vehicle.  The shim arrangement involves a large number of tapered shims of resilient non-metallic material of high compressive strength at yield, each of which has a different maximum dimension and each of which preferably has a color corresponding to the maximum dimension of the shim.  In use, a shim of the required thickness is in-serted between two sections of the axle housing to adjust the angle between them and hence the camber of the wheel. Because the shims are colored, it is possible to identify the particular shim that has been used after the axle assembly has been reassembled after insertion of the shim. The shims are of a resilient plastic material such as 40% glass filled nylon.  Each shim preferably has an annular rib adjacent its inner wall which engages the adjacent surfaces of the housing, or an adjacent shim, and acts as a seal.

Abstract: Abstract of the Disclosure A disc valve includes a seat ring having a butt portion anchored to the body of the valve and a seal portion which ex-tends axially from the butt portion.  The disc of the valve is axially aligned with the seal portion of the seat ring so that the valve is sealed via engagement of the seal portion with the periphery of the disc.  An annular cavity is formed about the seal portion of the seat ring and opposite ends of the cavity are vented to the valve chamber on opposite sides of the disc.  An elastomeric seal disposed in the cavity is responsive to pressures of opposite ends of the cavity to close the vent to the low pressure side of the disc such that the higher of the fluid pressures on opposite sides of the disc is exerted on the outer periphery of the seal portion of the seat ring to force the seal portion against the disc when the valve is closed.

Abstract: SINGLE SOLENOID UNIT INJECTOR                       ABSTRACT       A fuel injector (10) is provided for each cylinder of an internal combustion engine, the injector including an electronically  operated  control  valve  (146)  disposed between supply passage 42 and a timing chamber  (98)  to control the admission of fuel into and out of the timing chamber.  A primary pumping plunger (62) and a secondary plunger (90) are axially spaced within the central bore of the injection body, and a normally closed injection nozzle (14)  is situated at one end of the injector body.   A mechanical linkage (27, 28, 30) associated with the cam-shaft of the engine drives the primary pumping plunger (62) against the bias of a main spring (18).  The timing chamber (98) is defined between the plungers (62, 90) and a metering chamber (128) is defined between the secondary plunger (90) and the nozzle (14).      An electronic control unit (52) responds to engine operating conditions, and delivers a timing and metering signal to the control valve (146) to close the valve and seal the timing chamber for a controlled period of time. The sealed timing chamber forms a hydraulic link, so that the plungers (62, 90) move in concert during the injection and metering phases of the cycle of operation.  When the signal from the ECU is  terminated,  the  control  valve opens, and breaks the link so that the primary plunger (62) moves independently of the secondary plunger  (90) which is biased in a set position by a spring (96) after termination of the control signal.      The timing function can be adjusted by the ECU rela-tive to any preselected position of the crankshaft to optimize engine performance, while the metering function is achieved in a proportionate manner relative to the degree of camshaft rotation.  A cam (22), having a linear portion, controls the mechanical linkage, and thus the primary pumping plunger (62), to produce the proportional metering function.
