Abstract: ABSTRACT         A telephone switching system comprising a central office switching unit and a remote field switching unit controlled by the central office unit.  The field unit provides controlled connections between a number of trunks extending from the central office unit and a greater number of subscribers connected to the field unit.  The field unit additionally contains a number of intracall lines for establishing a connection between two sub-scribers without the need for sustained trunk connection after the call is established.  The central office unit includes a system controller comprising a microprocessor and associated memory units.          The system controller receives information interrupts from both the central office unit and the remote field unit as to subscriber calls, subscriber identity, trunk availability and overall system condition alarms.  Appropriate control signals are sent from the central office unit to the remote unit to establish the appropriate connections between the units for subscriber connections.  Control and data words interrupts travel between the central office unit and the remote field unit over a voice grade, duplex data channel.          Control and data words are in binary and serial encoded on PSK carriers transmitted through the data channel.  Each unit transmits a distinct carrier, and each unit contains a filter network to separate the incoming and outgoing carriers.  The control and data words include parity lists and error correction bits for correction of errors in the transmitted words by the system controller.  A phase lock loop in each unit demodulates the carrier to remove the serial words.

Abstract: ABSTRACT OF THE DISCLOSURE An elongated downrigger system having a relatively long extension arm for safely positioning the downrigger lines far from the propeller and hull of a boat.  The elongated downrigger system is equipped with a movable carriage assembly to permit the weighted end of the downrigger line to be readily grasped when it is desired to attach a fishing line, bait or lure, even though the extension arm is much longer than the average length of a human arm.  The carriage assembly has a glide member, such as a roller, to ride upon the long extension arm and has at least one cable guide, such as a pulley, to guide the carriage assembly on the cable.  A drive member is secured to the downrigger cable and engages a driven member on the carriage assembly to drive and move the carriage assembly to an inward attachment position when the cable is wound upon the downrigger reel.

Abstract: ABSTRACT OF THE DISCLOSURE   A lift truck has a log handling carriage head carried by a verti-cally movable boom.  The boom is pivoted to the truck frame below the opera-tor's cab to provide a clear line of sight from the cab along the top of the boom to the carriage head in any position of the boom.  The carriage head com-prises a pair of independently operable, vertically disposed, transversely separated, articulated claws.  The claws are pivoted to opposite side exten-sions of the outer end of the boom for improved visibility to the load.  Each claw includes a generally upstanding main carriage member, a fork extending forwardly from a lower end of such member, and a tusk curving forwardly and downwardly from the upper end of such member.  The fork and main carriage member of each claw pivot about a common transverse axis, and the vertical angle of each fork is adjustable independently of the other by pivoting its associate main carriage member independently of the other such member.  Each fork is free floating within limits relative to its main carriage member so that when the fork contacts the ground, its main carriage member may be piv-oted without moving the fork.  A tandem hydraulic cylinder and crank mechanism pivots each tusk relative to its main carriage member between open and closed positions.  Each tusk is operable independently of the other.

Abstract: 1.            Abstract of the Disclosure A temperature gradient zone melting process is disclosed wherein the temperature gradient is established substantially across only the molten zone by preferen-tially heating the molten zone.  In a specific embodiment, the mechanism for inputting heat to the molten zone involves exposing a substrate to optical radiation of a wavelength and magnitude for which the molten zone is absorptive and the remainder of the body is transparent. The molten zone thereby migrates through the body toward the source of optical radiation.

Abstract: ABSTRACT     A power Factor Monitoring and Control System for controlling the quality of a spot weld made in the automotive industry on assembly line welders.  The quality and strength of a spot weld can be correlated to a drop in resistance during the fusion process.  Rather than measuring this resistive drop at the welding electrodes by attaching external sensing means thereto, the control system of the present invention makes use of the phenomenon that a resistive drop also causes a change in the total load power factor further resulting in a change to the current extinction angle of a weld half cycle.  By determining the amount of increase or decrease that has occurred in the current extinction angle during a weld or a group of welds, a basis for the control of the welding heat is obtained.

Abstract: NITROGEN LIQUID TO GAS CONVERTER               Abstract A flameless nitrogen liquid to gas converter for providing high pressure nitrogen gas to treat oil and gas wells.  A diesel engine prime mover drives hydraulic pumps and motors to pressurize nitrogen and actuate an air fan.  Heat for converting the liquid nitrogen to gaseous nitrogen is obtained from the engine jacket water, the engine exhaust, and the hydraulic oil from the hydraulic pumps and motors.  Additional heat can be obtained from the hydraulic oil system by increasing the hydraulic system pressure with a hydraulic pressure control valve.  At least one of the hydraulic pumps and its driven hydraulic motor is in a hydraulic circuit which includes variable means for increasing the pressure in the hydraulic circuit, a hydraulic oil-air heat exchanger, and a hydraulic oil reservoir.  Hydraulic fluid from the other pumps and motors is transmitted through the hydraulic oil-air heat exchanger.          The system includes an in-line heat exchange system in series in the air flow from upstream to downstream in the following order:  hydraulic oil-air heat exchanger, engine water-heat exchanger, engine exhaust-air heat exchanger, nitrogen-air heat exchanger, and an air suction fan.

A follow up control system adjusts the transmission throttle valve cable according to the accelerator pedal position except under engine operating condi-tions associated with reduced fuel efficiency at which time the follow up control system is inter-rupted and the throttle valve cable is adjusted to initiate a downshift in the transmission.  The follow up control system is reestablished when the available power output in the higher gear is suffi-cient to satisfy the requested power output in an efficient manner.
