Title: Manually programmable robot with power-assisted  motion during programming

Abstract: Abstract:         A robot is disclosed having a plurality of movable links or members interconnected end-to-and in series.  Associated with each is an actuator and position transducer.  Some of the links are relatively massive and cannot be readily moved without power assistance when the robot is manually programmed, while other links or members, namely those constituting the wrist, are relatively lightweight which permits movement thereof without power assistance during manual programming.  A force transducer is connected in series with the output element of the robot in association with one of the massive links located between the wrist and the station-ary base on which the robot is mounted.  The transducer senses forces during programming applied to the massive links via the wrist when manual programming forces are applied to the robot output.  The force transducer provides an output signal for each of the massive links correlated to the component of the manual programming force transmitted thereto via the wrist.  These force transducer output signals are all compensated for inertial forces applied to the massive links due to acceleration of the wrist mass, while only those force transducer output signals associated with massive links moving in a vertical plane are compensated for gravita-tional forces applied thereto resulting from the effects of wrist mass.   During programming, the inertial and/or 1,125,892 gravitational force compensated force transducer output signals are applied to the actuators of their respective-ly associated massive links to move the massive links in power-assisted fashion, while the lightweight links of the wrist move in unpowered fashion in response to the manual force applied thereto during programming.  The power-assisted motion provided to the massive links by their respectively associated actuators, coupled with the unpowered motion of the lightweight links constituting the wrist, collectively produce motion of the robot out-put element in the direction to which the manual force is applied thereto during manual programming.         The transducer outputs can also be compensated for nonuniform acceleration of the wrist by modifying the force transducer output in accordance with the third derivative with respect to time of the displacement of the wrist.  This enhances the "feel" of the robot during manual programming.

Abstract: ABSTRACT OF THE DISCLOSURE            A reference pulse signal is applied to both a detector multiplier and a gate circuit by utilizing the same trans-mission path, i.e., same circuit.  More specifically, the reference pulse signal is supplied to the detector multiplier and gate circuit through a transistor and a resistor.  Therefore, the reference pulse signal received at the base of the transistor constituting the detector multiplier is substantially identical in level and pulse width to the reference signal received a-t the base of the transistor constituting the gate circuit. Owing to the use of the same transmission path described above, the timing of pulse detection coincides very accurately with the timing of gate control.  Therefore, a signal can be detected accurately and the efficiency of phase detection is improved.

Abstract: ?-???? METHOD AND APPARATUS FOR INDUCTIVELY HEATING VALVE SEAT INSERTS               Abstract A method and apparatus for heating a conical valve seat surface of a valve seat ring insert which has been previously press fitted or molded into an engine component such as an engine head.  The method and apparatus includes mounting an inductor for reciprocal movement axially toward and away from the valve seat of the engine head and biasing the inductor toward the valve seat, encircling the induc-tor with an axially biased electrically conducting hollow ring-shaped magnetic flux shield through which a coolant is circulated, and moving the inductor and conducting ring shield toward the valve seat of the engine head to locate the inductor in a preselected position providing the neces-sary magnetic coupling gap between the inductor and valve seat surface of the valve seat insert while the conducting ring shield is maintained in heat transfer surface contact with and stray flux shielding relation to the portion of the engine head immediately around the valve seat surface of the insert.  Energization of the inductor results in inductive heating of the valve seat surface of the insert preparatory to the quench hardening thereof.  During the inductive heating of the insert, the cooled conductive ring shield acts to prevent excessive heating, by induction and by heat conduction from the heated insert, of the aluminum metal of the engine head around the valve seat insert such as would normally destroy the pressure fit therebetween and damage the surrounding aluminum metal.

Abstract: ABSTRACT OF THE DISCLOSURE A well casing cutter which includes a plurality of cutting well blocks and associated cutting wheels movable radially outwardly through apertures in a cylindrical housing of the cutter for engagement with a well casing.          Upon rotation of the cutter the cutting wheels cut into the casing in response to fluid pressure applied to a pressure chamber above a piston.  The piston is slidable along an axis of the housing.  When the cut is complete valve means releases the pressurized fluid into the well casing exterior of the cutter housing through the apertures.  The movement of the pressurized fluid past the outting wheel blocks blows out any cuttings, dirt and other accumulated material which might otherwise jam movement of the cutting wheel blocks. A check valve means prevents blow back of sand, dirt, and other material into the pressure chamber.

Abstract: Abstract of the Disclosure In a process for deaerating and purifying both the water which is recirculated in a coolant loop through a stack of fuel cells and the make-up water for the coolant loop, a portion of the water from the coolant loop is blown down into a deaerator water reservoir to which make-up water is added as required by the coolant loop.  Water is withdrawn from the reservoir, purified, and then introduced into the coolant loop at a rate sufficient to maintain the desired amount of water circulating in the coolant loop.  The blowdown provides some of the heat for deaerating the water; and the rate of blowdown flow into the reservoir is sufficient to maintain an acceptable level of impurities in the recirculating coolant loop water.  Preferably, the blowdown f low rate is controlled as a function of the amount of make-up water required to be added to the coolant loop.

Abstract: ABSTRACT           A change speed transmission device using gears employs a shift drum mounted parallel to the driving and driven shafts.  The shift drum is turned one-quarter revolution at a time to cause a shifting mechanism to produce a low speed drive, and an intermediate speed drive, and a high speed drive between the shafts, and then back to neutral.  A pivoted pawl engages an abutment on the shift drum to limit turning movement of the drum.  An element frictionally engages a member fixed to rotate with the driven shaft and serves to bias the pawl to engage the abutment so that the shift drum is prevented from turning directly from a high speed shift position to a low speed shift position.

Abstract: Forging Process for the Manufacture of Track Chain Links Abstract The invention described herein concerns a forging process for the manufacture of track chain links, especially for worksite machines and vehicles; this process produces links that conform to the tolerances required by the dimensions and the surface quality of opposed attachment mounting and link contact surfaces and nut seats of finished links without it being necessary to machine these surfaces or nut seats.         This process includes heating a metal billet in an electric furnace, the billet having a mass that is approximately equal to that of a finished link, preforming the billet, then flat stamping the heated billet.  A combined shaping and levelling step carried out on the stamped piece forms parallel opposed sides and nut seats in predetermined spaced relationship to each other.  The resulting link is controllably sized and then subjected to a heat treatment.         At the end of this process, which requires no machining, a link is obtained whose opposed surfaces and nut seats have geometric and dimensional relationships that are conform to the limits of the required tolerances.
