Abstract: Abstract of the Disclosure Perfluoroalkoxy (PFA) fluorocarbon resin is fusion bonded to polytetrafluoroethylene (PTFE) resin to provide united sections thereof and to provide a bonded or welded inter-connection between separate sections of PTFE resin.  An example of the latter is a PFA resin welded section joining the ends of the PTFE resin liner and jacket encasing a reinforcing core in a dip pipe.  The welds are obtained under minimal pressure, generally below about 40 psi, at a temperature above the gel point of the PTFE resin, generally between 635° F. and 710° F., with subsequent slow cooling under pressures somewhat higher and generally ranging between about 55 psi and 150 psi.

Abstract: FEED AND ALIGNMENT SYSTEM FOR PANELS          Abstract of the Disclosure A vertical stack of generally horizontal panels is contained within a bin structure and rests on several rollers. At the upstream end of the system an injector is operative to push a predetermined number of panels linearly from the bottom of the stack toward the downstream direction.  Once the injector shoes push the predetermined number of panels from the bottom of the stack, a powered roller acts to move the stacked panels toward an aligning station.  After the stacked panels clear the bin structure, a crowding chain operates to align the long edges of the panels such that they will be properly aligned when they enter the downstream work station.

Abstract: FIBER OPTIC CONNECTOR WITH AXIAL TOLERANCE RELIEF          ABSTRACT OF THE DISCLOSURE         An elongated hollow termination pin assembly for mechanically terminating a fiber bundle of a fiber optic cable. The pin assembly includes an elongated hollow pin with a coaxially slidable outer sleeve and an O-ring of resilient material mounted in a groove about the pin immediately adjacent to the end of the sleeve toward the terminal end of the cable. A backward facing shoulder is provided about the circumference of the sleeve so that a retaining clip within the connector shell can restrain backward axial move-ment of the sleeve. The pin can slide within the sleeve, however, and is resiliently constrained by the O-ring to provide a positive abutment force at the interface of the fiber bundles, dampen contact vibrations, and absorb axial tolerances. Alternatively, the O-ring may be positioned between a forwardly facing shoulder on the connector body and the retaining clip, with a tine on the clip engaging a rearwardly facing shoulder on the pin.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus is disclosed for determining the position of a focussing plans of an image within an optical device which includes an optical imaging system.  The apparatus is provided with a pair of optical deflecting systems so disposed and arranged in front of the optical imaging system that each half pupil of the optical imaging system receives light exclusively from a respective one of the deflecting systems of the pair.  An object viewed by the imaging system is imaged at or near an optical grating and relative motion between the image and the grating is effected.  Photo-electric receiver means are arranged to generate electrical output signals in response to respective ones of partial light fluxes received from the grating and the output signals are processed to provide further output signals indicative of the position of the focal plans.  Preferably, a reference beam is transmitted along paths traversed by the partial light fluxes corresponding to the respective pupil halves of the imaging system. Further electrical signals indicative of changes in transmission characteristics of at least one of the paths are generated photo-electrically in response to light from the reference beam.

Abstract: ABSTRACT OF THE DISCLOSURE   For welding pipeline pipe in the low ambient temperatures, encountered in extreme latitudes that may range from + 32°F to - 70°F and possibly lower, the induction heating of the pipe in the area of the weld joint prior to welding and at selected other times such as while the weld is being made, during quenching and for normalizing.  A split-ring pancake induction heater is used comprising a pair of separable jaws that may be opened for lateral application to the pipe and closed to circumferentially embrace the same and wherein each of the jaws constitutes a separate induc-tor.  Unlike the welding difficulties that would be caused by a ring induc-tor, the split-ring nature of the present inductor tends to break up unwanted eddy currents giving improved weld disposition quality and production speed. The unit is self-contained and readily movable along the pipe-line route. This method of induction heating comprises the steps of preheating the pipe in the area of the weld joint and heating it while the weld is being made. It provides also for further heating during the quenching and heating for normalizing.

Abstract: ABSTRACT OF THE DISCLOSURE       An electric trolling motor apparatus includes a solid state motor control housed within the lower propeller unit to establish a constant speed in combination with continuous monitoring to prevent damaging current levels.          The forward nose cone of the unit has an inner transverse platform with cast radial ribs and with a shape to receive the slightly smaller mounting frame of a power transistor with a pair of central lateral recesses.  A circuit board is formed with a corresponding configured opening.  The transistor is bolted to the platform for heat transfer and supports the circuit board.  The transistor is connected as a voltage regulator to maintain an essentially constant voltage and resulting speed of the motor.  A self-protecting, compensating means positively reduces the current under conditions which would tend to damage the control system.          A sensing amplifier has a summing input connected to in-dividual sensors of the voltage, current and temperature parameters of the power transistor and an output summed with the speed signal to the transistor and provide an overriding motor current control.  An extremely high level of any single sensed parameter effectively reduces the input to the tran-sistor regulator.  A somewhat lower sensed level of the com-bination of any two of the parameters similarly responds and sensing of all three parameters at a further reduced level also similarly responds to reduce the motor speed.
