Title: Pellet lenght and end squareness inspection apparatus
Inventor: WILKS ROBERT S
IPC: G01B7/28

Abstract: PELLET LENGTH AND END SQUARENESS       INSPECTION APPARATUS     ABSTRACT OF THE DISCLOSURE         Apparatus for determining pellet length and end squareness which includes a base supporting a pair of linear variable differential transformers (LVDT) between which a pellet is placed for measuring end squareness.  The LVDT's are perpendicularity detectors and each includes appropriate windings contained in a housing and an arma-ture axially slidable therein.  The armature is mounted on a shaft having extensions on opposite ends thereof.  A swivel plate is attached to one end, while the other end is supported in a framework for the inspection apparatus, the arrangement being such that the housing containing the windings moves axially relative to the stationary armature.          When a pellet is placed in position, each detector is advanced toward the pellet until its swivel plate contacts the pellet ends.  If the pellet ends are not square, the swivel plates cock at an angle, thereby displacing the windings with respect to the armature.  The relative dis-placement will be proportional to the tangent of the angle between the pellet ends and a plane perpendicular to the pellet axis.  The pellet length is measured by a second LVDT which includes windings in a stationary housing.  The armature moves relative to the windings and measures the relative distance between the swivel plates so that as the perpendicularity detectors sense the end squareness, the third LVDT senses pellet length along its axis.  The output from the LVDTs is supplied to conventional readout circuitry and an indicating device which shows pellet length and end squareness.

Abstract: VEHICULAR REPEATER     ABSTRACT     In a two-way communications system involving portable-mobile-base station transmission, a priortization method prevents interference caused by more than one mobile repeater at a single location relaying simultaneously, or by a lowband transmission skipping in from another location.          When a repeater enters the system at a location, it monitors the base and portable channels, and if there is transmission activity on either channel it goes to a non-priority state.      If there is no activity, a silent carrier burst is momentar-ily transmitted on the base channel, then the repeater goes to a non-priority state.  Unless a repeater at the scene is in the priority state, each other mobile unit, upon detecting the burst, begins to repeat it out on the portable channel.          When interrupted by its interrupt clock, the repeater listens for a short interval on the portable channel and if any transmission is heard, remains inhibited or in "receive" mode.  The last mobile repeater to be interrupted will, of course, hear no other transmission and will return to "transmit".  This unit will be established as the only unit in the priority state at that location.  Any portable channel transmission will prevent base channel transmission from being repeated out on the portable channel, thus a portable-to-portable or portable-to-base transmission will have priority over base-to-portable or "skipped-in" trans-mission.  When the unit in priority leaves or switches channels it is removed from the priority state and transmits a momentary silent carrier burst so that a new priority unit is established as before.

Abstract: ABSTRACT       Playback apparatus for television signal recorded on a record carrier in oblique signal tracks, the television signals containing synchronizing pulses. The apparatus for scanning the tracks consists of a rotary transducer arrangement with two magnetic heads whose effective gaps have mutually dif-ferent azimuth angles.  There is provided a detection circuit for phase shifts between consecutive pulse trains.  The cir-cuit receives the trains of synchronizing pulses separated from the reproduced signal as an input signal and supplies a pulse-shaped output signal whose magnitude and polarity correspond to the instantaneous phase-shifts.  This output signal is applied to a circuit for the formation of the difference between the out-put signals of the phase-shifts detection circuits whose output signal in its turn serves as and additional control signal for a servo system which is adapted to control the phase relationship between the signal tracks recorded on the record carrier and the tracks on the record carrier which are actually scanned by the magnetic heads.

Abstract: Abstract The present method and apparatus are believed to be the first to achieve, at least in a practical manner susceptible of widespread use on large numbers of joints, both proper engagement and proper makeup torque between tapered threaded members such as sections of pipe in an oil well or pipeline.           In accordance with one embodiment, presently preferred, gage means are employed to determine the actual hand tight plane of each tapered threaded member, and a mark is made on each such member in predetermined relationship to the hand tight plane.  Such marks are then employed for field inspection of joints which have been made up to a predetermined, measured, desired makeup torque.           In accordance with another embodiment, the members (for example, casing and tubing sections and collars) are made up until the marks on the collar and the pipe are at a predetermined axial distance from each other at a predetermined makeup torque or pre-determined desired range of makeup torques.  In accordance with another embodiment, not preferred, only one of the two members is gaged and marked.  Gaging and marking may be effected rapidly, even under adverse field conditions.  The apparatus and method employ automatic centering means and associated elements which make it possible to power-screw a gage onto a pipe section rapidly, with no substantial start-up problems.  Furthermore, the apparatus and method employ a precision pipe-marking means, and preferably employ a gage card having a predetermined relationship to the marking means.

Abstract: ABSTRACT OF THE DISCLOSURE            Method and apparatus are described for automatically loading film transparencies into pre-closed slide mounts either of plastic or of cardboard material and having an internal pocket for receiving the film transparency which is inserted through an openable region near one edge of the mount.   In loading operation, wedge means temporarily spread the openable portion of the slide mount, defining a passageway for the film transparency to pass through into the mount, and then the two sides of the mount are allowed to spring back to their closed position after loading.   Advantageously, the film transparency is cut off from the filmstrip before loading, with the freshly cut end of the strip serving as pushing means for pushing the film transparency into its mount, and thus low inertial forces are involved, because the individual cut trans-parency has only a small mass to be accelerated and moved.   The film strip is bowed into a longitudinally extending arch for providing longi-tudinal stiffness for pushing the transparency.   A common drive assembly performs the multiple functions of advancing the preclosed slide mounts from the stack station, through loading and printing stations and into the outlet, while also transporting the filmstrip to push the cut film transparency into the internal pocket in the slide mount, and thus a compact machine of relatively low power consumption can be constructed to embody this invention.   In this embodiment, the edgewise movement of the pre-closed slide mount into the loading station achieves the slot spread wedging action, while the apparatus provides a convenient view of the advancing film strip and of the cut transparency during actual loading into the slide mount. An improved pre-closed slide mount is described.
