Abstract: ACCESSING MAGNETIC HEAD ARM ASSEMBLY AND SUSPENSION   Abstract of the Disclosure A magnetic head arm assembly has a suspension for an air bearing head slider that includes a substantially rectangular flexure with two parallel flexible narrow fingers and relatively stiff crosslegs, and a central finger to which the slider is attach-ed.  A load beam is fastened to the flexure so as to engage a load protuberance formed with the central finger. Flexibility of pitch around a longitudinal axis and roll around an orthogonal axis are provided thereby.  Stiffness and rigidity against radial, circum-ferential and yaw motions are also realized.

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention concerns a method of and a sensor for detecting the activity of gaseous anhydrides in an oxygen-bearing gas.  It comprises a solid state electrolyte element having oxy-anions of the element forming the anhydride to be detected, a re-ference electrode being in contact with the electrolyte element, a detection electrode remote from the reference electrode and also in contact with the electrolyte element.  A metal salt material is placed nearby the reference electrode, that metal salt being se-lected such that it evolves an anhydride gas identical to the an-hydride to be detected.  The electrolyte and detection electrode are arranged such that they are free to come into contact with the gaseous anhydride to be detected whereas the reference and detection electrodes are arranged such that a difference of poten-tial occurs therebetween when a sample of the anhydride to be detected is contacted with the detection electrode and with the electrolyte element.  The electrolyte element and the metal salt material are heated to a temperature such that a logarithmic va-riation in the concentration of the anhydride to be detected causes a proportional and substantially linear variation in the difference of potential, that temperature being below the fusion temperature of said electrolyte element.  A potentiometric measurement device is connected to the electrodes for measuring the activity of the anhydride to be detected by measuring the set difference of potential.

Abstract: ABSTRACT           Particulate graphite having a particle size not greater than about 1500 microns is impregnated with a poly-merizeable organic compound in liquid form.  The impregnated particles are treated with a hot aqueous acid solution to at least begin the polymerization reaction and remove excess impregnant from the outer surface thereof.  The treated particles are heated to complete the polymerization and then blended with particulate nuclear fuel.  A nuclear fuel body is formed by joining the blend into a cohesive mass using a carbonaceous binder.

Abstract: FLUID PRESSURE BRAKING SYSTEM                      ABSTRACT OF THE DISCLOSURE A fluid pressure braking system for an articulated vehicle is dis-closed.  The system includes valving which senses a failure in the brake service line connection between the tractor and trailer portions of the vehicle.  If a failure in the service line connection is detected, the valv-ing closes communication between the tractor and trailer portions of the vehicle and causes actuation of the trailer emergency brakes.  When the brakes of the vehicle are released, the valving automatically resets itself to release the trailer emergency brakes.

Abstract: INVENTOR:  Lecon WOO TITLE:  THERMOMECHANICAL ANALYZER     ABSTRACT OF THE DISCLOSURE        A thermomechanical analyzer is adapted to measure stress or spring in a sample material by the use of a flat, passive spring, having a known modulus of elasticity, in conjunction with an axially displaceable shaft which mechan-ically links the spring and the sample together.  The linkage is such that the sample under test and the spring are mechan-ically connected in parallel, i.e., each undergo equal dis-placement.  A transducer senses axial displacement of the shaft such that the magnitude of the shaft displacement is related to the stress in the sample.  The sample may be sub-jected to temperature variations during the test cycle.

Abstract: AUXILIARY INTERLOCK SWITCH WITH INTERCHANGEABLE     AND REVERSIBLE CHISEL-SHAPED CONTACTS AND         SPRING BIASING MECHANISM                  ABSTRACT OF THE DISCLOSURE           An auxiliary interlock switch for a DC contactor has a reciprocable one-piece insulating contact carrier and plural bridging contacts interchangeably mounted thereon in alternative positions to provide different desired arrangements of normally open and normally closed contact sets with the stationary contact posts.

The bridging contacts may be easily removed in the field and reassembled in desired contact configuration and are of resilient metal with bifurcated ends having "chisel" surfaces which provide high unit area contact pressure and plural points of engagement with each stationary contact post to thereby increase electrical reliability.

The remote electronics include a ringing generator and a supervisory circuit to implement normal telephone supervision over the carrier channel.          The ringing generator is a dc-to-dc converter for stepping the battery voltage up to the ringing voltage level.  In order to interrupt this unipolar ringing voltage and thereby to energize the telephone ringer, a switching circuit is provided including a transistor in shunt with the ringing voltage supply to provide a return path for alternate half cycles or ringing current  A constant current source from a low voltage supply connected to the base of the transistor provides bias current to saturate the transistor yet minimizes the amount of dissipated power.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention is directed generally to connectors, and more particularly to a connector for fiber optic cable segments.  Prior art connectors for fiber optic systems have not been completely satisfactory, particularly where frequent connects and disconnects must be made under adverse environmental conditions, or where multiple fiber optic circuits must be connected in a single connector, because of the difficulty of maintaining an accurate consistent alignment between the ends of coupled cable segments under such conditions.  The present invention is directed to a connector which provides more accurate and consistent alignment of the terminal ends of fiber optic cable bundle segments under these conditions.   The present connector comprises a mating plug and receptacle each including insert members having aligned passageways wherein the terminal ends of the fiber optic cable segments are disposed.  An alignment sleeve within the passage-ways fixed to one insert member and slidable received by the other receives the terminal ends at respective ends thereof to maintain the terminal ends in axial, transverse and angular alignment.
