Abstract: ELECTRONIC TRACK CURRENT SWITCHING RELAY SYSTEM     Abstract of the Disclosure An electronic system which emulates the operation of a polar relay for -applying coded pulses to railway tracks has separate signaling circuits having signaling devices responsive to a separate inputs which provide operating power to the circuits. The circuits are interlocked by connecting the inputs to the signaling devices in inverse relationship. One input excludes the other. The signaling devices may be light emitting isolators with switching transistors which control the application of current pulses through the rails of the track while isolating the track battery which supplies the current for these pulses from the local battery which provides the inputs to the signaling circuits. The signaling circuits establish current paths through the light emitting signaling devices at predetermined times after the inputs are applied to emulate the pickup and drop away time of the polar relay. The switching circuits use complementary symmetry power transistors which provide fail safe operation in the signaling system in the even of a short-circuit failure mode throughout.

Abstract: Title AXLE DRIVE ASSEMBLY       Abstract A full-floating axle drive assembly  for propelling a vehicle includes a shaft having   a splined end to which a splined drive member is axially and non-rotatably secured.  The drive member is secured to the splined end of the shaft between the bottom of the shaft splines and a forged flange end.  In a preferred embodiment, the shaft extends through an axle tube on which a wheel hub is fully supported by bearings.  The drive member is secured to the wheel hub which is rotated thereby about the axle tube.                            Background This invention relates to vehicular drive assemblies, and particularly to fully floating drive axles.  Prior construction of axles in the light to medium truck category has involved the forging of a one-piece axle and axle shaft flange r and has necessitated flange machining to rather close tolerances to provide the finished drive axle.  The production of various shaft lengths has been relatively cumbersome and expensive, since production line changes involving resetting of equipment has been required.  Even where such axles have been of two-piece construction, viz. axle shaft flanges splined to axle shafts, as for example in certain off-highway construction and industrial equipment, the flanges have in general been axially secured to the shafts by snap rings, or simply left unsecured. When left unsecured the axles have been subject to chucking under load changes and/or to end thrust damage which occurs upon the cornering of the vehicle as result of relative axial movement of the shaft within the axle flange. Summary of Invention The drive assembly of this invention contains a drive axle shaft having a splined portion at one end, over which a splined drive member is axially and non-rotatably secured between (1) an inner extremity of the splined portion and (2) a forged flange formed at the end of the axle shaft.  The axle shaft end is not subject to chucking or end thrust, as the axle shaft does not move axially relative to the drive flange.  Moreover,

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus is disclosed for quantitating relatively small amounts of a clinically significant compound which had been fluorescently tagged.  The apparatus has a transparent cell for holding a prepared liquid sample (which includes fluorescent particles).  A light source generates a stable light beam that is focused on -the sample in the cell so that the beam causes fluorescent emissions by the particles in the sample. The intensity of the emissions is a function of the intensity of the light beam and the concentration of the fluorescent particles in the sample.  A detector in optical communication with the cell receives and senses photons defining the fluorescent emissions.  The number of sensed photons is counted and the total count from the sample over a fixed time period is a measure of the number of fluorescent particles in the sample.  A microcomputer system is further disclosed including a primary microproces-sor which is interfaced via latches and buffers on a data bus to a system memory, system peripherals, and major system subassemblies.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus measures the thickness of a tube wall while the tube experiences motion relative to the apparatus.          A radiation beam is generated and positioned relative to a tube so that the beam sequentially passes along at least three selected beam paths.  Each beam path passes through at least two distinct measuring points within the cross section of the tube wall.  At least three measuring points are passed through by at least two different radiation beams.  The beam intensity of the transmitted beam after it passes through the tube wall is detected to produce a detected value of the intensity that is supplied to a processor that determines the tube wall thickness based upon the detected value after it has been transmitted through the tube and the known intensity value of the beam before it was transmitted through the tube.  The result is apparatus that is more compact and versatile in adapting to tubes of different diameters.

Abstract: ABSTRACT OF THE DISCLOSURE     METHOD AND APPARATUS FOR  SURFACE HARDENING CAMS     This invention relates to a method and apparatus for simultaneously surface heat treating the wear surfaces of a multiplicity of cams on a cam shaft by transferring to the cam surfaces the energy of a concentrated beam of elec-trons. The electron beam is directed for a predetermined time to a desired spot on the surface of the said cams and is caused to move incrementally from one to the next of a predetermined matrix of spots on the work surface as the cam shaft is being rotated.  After the predetermined matrix pattern has been repeated one or more times, the beam is then directed sequentially from one cam to the next and the process repeated until all wear surfaces on the cams have been treated.          The predetermined pattern is projected over the desired surface of all the cams a predetermined number of times so that the material to be heat treated at the intersection of the plane described by the beam's motion and all the cam surfaces being, in effect, simultaneously heat treated is brought above the transformation temperature and maintained below the melting temperature by close control of the electron beam parameters. the beam power and dwell time of the beam at each print are programmed in accordance with the linear velocity of the par-ticular cam surface being, instantaneously treated in such a way that the instantaneous energy per increment of surface of each of the cams is made to follow a predetermined law of instantaneous energy input vs. angular position of the cam.          Each heated element along the surface of the cam as it moves from under the beam is rapidly cooled by the underlying mass of cold material to effect a quench.

Abstract: Abstract of the Disclosure A reciprocating traversing apparatus discharges material onto, inspects marks, or cleans a device that it is traversing is provided that has reduced requirements for a driving motor, and has smoother traversing motion.  A traversing mechanism has a driving motor with horsepower and torque requirements to maintain operational speed of the reversible tra-versing mechanism.  The driving force to overcome inertia of the traversing mechanism when it reverses to traverse in the opposite direction is pro-vided by a gas cylinder with extending arm.  The traversing mechanism mov-ing in a track has a gas cylinder at each end of the track.  The extended arm of the cylinder engages the mechanism as it approaches one end of its traverse.  The arm is depressed, and when the motor reverses the arm is extended by gas pressure to its original position.  By the extension  the arm accelerates the mechanism up to is operational speed.  The motor con-tinues to drive the mechanism to the other end of the traverse, where the mechanism engages the extended arm of the other gas cylinder.
