Abstract: ABSTRACT         The invention is concerned with a heating installation for home or industrial use, comprising a boiler enclosure containing an intermediate liquid to be heated and an internal combustion engine suspended in the boiler and at least partially submerged in the intermediate liquid for operating in the submerged condition so that heat generated by the operation of the engine is transferred directly to the intermediate liquid.  An exhaust pipe means for removing exhaust gases is connected to the internal combustion engine and is at least partially submerged in the intermediate liquid so that heat from the submerged portions of the exhaust is transferred directly to the intermediate liquid.  The installation further includes a heat pump having a condenser, an evaporator, and a compressor which is driven by the internal combustion engine, the compressor being the only load of the internal combustion engine, so that at lower temperatures the amount of required compression and resulting load increases, producing therefore a greater thermal dissi-pation from the internal combustion engine, while heat from the condenser is transferred to the intermediate liquid with-in the condenser.  Heating members are located in the premises to be heated and are supplied with a heating fluid heated by the intermediate liquid of the boiler.  The condenser is situated downstream from the heating members and upstream from the boiler so that the heating fluid flowing from the heating members to the boiler is heated during its passage through the condenser.  The invention is particularly useful as a boiler for a heating system.

Abstract: ABSTRACT OF THE DISCLOSURE        A circuit breaker having a latching mechanism for opening breaker contacts, and a solenoid for releasing the mechanism upon overload, includes means for sensing current through a circuit subject to interruption by the breaker.  The sensed current is converted to a voltage proportional thereto.  A current rating plug and recepta-cle system, responsive to the proportional voltage, pro-vides a standardized voltage.  The proportional voltage is applied across a resistor in series with parallel con-nected permanent shunt resistor and replaceable plug resistor.  The standardized voltage is obtained across the parallel connection.  A peak detector provides an approximate true peak value voltage of the standardized voltage.  An instantaneous trip circuit, including a threshold detector compares the approximate peak value voltage with a preset threshold value and, when it equals or exceeds the preset threshold value, a trip signal is generated.      A long term delay circuit squares the approximate peak value voltage.  The squared approximate peak value voltage is compared with a reference voltage.  A voltage controlled oscillator is responsive to a signal applied to a voltage controlled oscillator when the squared approximate peak value voltage exceeds the reference voltage.  A pulse counter is coupled to the voltage con-trolled oscillator for providing a trip signal when a predetermined count is achieved.  The pulse counter is reset when the squared approximate peak value voltage ceases to exceed the reference voltage.      A short term delay circuit means compares the approx-imate peak value voltage with a reference voltage. Similarly, a separate voltage controlled oscillator is responsive to a signal applied to a separate voltage controlled oscillator when the approximate peak value ,636 voltage exceeds the reference voltage.  A separate pulse counter provides a trip signal upon achieving a predeter-mined count, and is reset when the approximate peak value voltage ceases to exceed said reference voltage.      Upon detecting a ground fault condition, a trip sig-nal is provided.  Upon the presence of any trip signal applied thereto, an OR circuit provides a control signal to the gate of an SCR.      A thermal switch is coupled across an anode and a cathode of the SCR.  A supply voltage is applied across a serial connection of the anode, the cathode., and the solenoid.

Abstract: VEHICLE MIRROR ASSEMBLY               ABSTRACT OF THE DISCLOSURE         A day/night rearview mirror assembly for vehicles including a one-piece, molded, resinous mirror case having flexible, resilient portions and a substantially rigid pivot actuator which is biased by the case into either a day or night position.  Movement of the actuator changes the position of the case and mirror element thereby changing the amount of light reflected.  An interference fit between supports for the actuator within the case and the pivot actuator expands and pre-stresses the case to provide a predetermined biasing force which must be overcome by a pivoting force to move the actuator between its positions.          A continuous lip extending around the periphery of the case allows snap-in insertion and permanent retention of a preferably prismatic mirror element.  The retaining lip is sized to maintain coverage of the edge of the mirror element even during flexing of the case while the actuator is pivoted.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention provides an improved container loading mechanism for automated packaging machines.  In particular, a container loading mechanism is disclosed which has a fixed segment and a movable segment, which is positionable either for container loading or aligned with the fixed segment for urging containers to a container feeding position.  The mechanism is positioned relative to the packaging machine such that the movable portion is adjacent the discharge of the packaging machine, thereby simplifying the loading of containers as the operator is normally near the discharge end of the machine.  The mechanism includes biasing of the movable segment, preferably by a counterbalance arrangement, further simplifying the loading operation.  The mechanism also includes several design features which reduce the possibililty of containers jamming.  As the device allows for gravity feed of containers, both segments are angled relative to the horizontal to ensure the containers are gravity fed to the container feeding position.

Abstract: METHOD FOR INDUCTIVELY HEATING VALVE SEAT INSERTS    (Abstract of the Disclosure) A method for heating a conical valve seat surface on a ferrous seat ring insert which is fixedly received by a bore in an aluminum engine component.  The method involves high power induction heating including the steps of locating an inductor adjacent the valve seat surface and then energizing the inductor by a power source having some predetermined frequency and elevated power rating.  The method also includes the step of maintaining the inductor in an energized condition for some predetermined period of time to transform the metal forming the valve seat into an austenitic structure to a preselected depth.  The steps of energizing and maintaining are coordinated such that the desired transformation is obtained in a very short time interval.  This then advantageously prevents deleterious expansion of the insert heat transfer through the insert to the aluminum engine component which would otherwise adversely affect the close fitting relationship between the insert and bore.
