Abstract: ABSTRACT OF THE INVENTION         In the improved operating mechanism of the instant invention there is associated with the rotatable contact-operating arm an abutment member, such as a plate, for example, which is associated with the contact-pressure spring, and a reverse-current loop arm pivotally mounted to the contact-actuating arm has a nose portion bearing on said abutment member or plate, and operable during the de-energized condition of the magnet to act in an opening direction against said abutment plate, and have its fulcrum point at the pivot-shaft location between the contact-actuating arm and the movable contact stem.  Thus, magnetic forces are brought into play to redirect the reverse-current loop effect, and to pry, in effect, the welded contacts apart, and thereby assist the opening accelerating springs of the circuit-interrupter or contactor.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and mechanism for determining forces on a casting as it solidifies in a continuous-casting machine.   A plurality of roll-pairs of an otherwise conventional curved roll-rack are equipped with means (e.g. load cells) which show the compressive load exerted  by the different roll-pairs on the casting. The roll-pair beyond which no further upward trend in compressive   load occurs  marks the plane at which the casting first solidifies throughout its cross section, since beyond this plane the  casting no longer has a liquid core tending to bulge the skin and separate  the rolls.  Whenever the load on a roll-pair departs substantially from the  norm, the indication is that  these rolls of this pair are improperly gapped (that is, the spacing between roll faces is  either too great or too little).

Abstract: ABSTRACT OF THE DISCLOSURE         A demand cardiac pacemaker is disclosed as comprising an input sensing circuit portion of improved sensitivity to heart beat signals of relatively low amplitude.  In particular, the input circuit portion includes a first sensing, bipolar transistor biased by a GaAsP light-emitting diode (LED), and a second amplifying, bipolar transistor whose base is coupled to the collector of the first transistor.  Further, the output of the second transistor as taken from its collector is fed back through a suitable shaping circuit to the emitter of the first transistor, whereby controlled high gain and desired frequency/amplitude discrimination characteristics are achieved from the first and second transistors, so that the input sensing portion of the pacemaker circuit is responsive to heart signals above a predetermined level without sacrificing gain.

Abstract: CODE OPERATED SWITCHING DEVICE FOR COMMUNICATION SYSTEMS AND THE LIKE     Abstract of the Disclosure The embodiment of the invention disclosed herein is directed to a code operated switching device having a receiver for handling RF frequencies in a superheterodyne fashion without the need of local oscillators, or the like at the receiver.  Input means is provided for receiving first and second RF frequencies having a predetermined frequency difference.  The RF frequencies are FSK modulated simultaneously, one frequency increasing and the other decreasing, so that the frequency difference will produce a control signal at the out-put of an FM audio discriminator circuit.  The control signal can be code modulated with series digital pulse information and applied to a code logic circuit that will detect if the proper code for the receiver has been received.  If the proper code is received the logic circuit will energize an active control element such as a relay or the like to allow data to be transmitted back through the switching device.

Abstract: ABSTRACT OF THE DISCLOSURE       Processing optical video discs may result in modulation of the duty factor of the pits and lands which constitute a spatial representation of a stored carrier signal frequency modulated with program information.  Such modulation of duty factor introduces spurious components that are detri-mental to image reproduction if the frequency of the stored carrier signal is not at least twice the highest video frequency component to be reproduced.  A correction signal is developed and used to at least partially cancel the effect of such spurious components.

Abstract: ABSTRACT OF THE DISCLOSURE           In a steam iron with a fill opening to an interior water tank above a heated soleplate with a steam generator and ports to direct steam through the soleplate, an improve-ment is provided for delivery of surge of steam by a generally slanted control/pump assembly from upper forward to lower rear and comprising a pump cylinder communicating through its top with the tank and through its bottom with the generator through a metering orifice.  A piston slidable in the cylinder moves between an upper position against a valve seat at the cylinder top to seal the cylinder from the tank for dry ironing, through an intermediate position establishing fluid connection between the tank and generator for continuous steaming, and into a lower position interrupting the fluid connection and trapping fluid below the piston.  A slidable control button on the forward iron handle moves and maintains the piston in a selected one of the above positions and the control is selectively operable to momentarily lower the piston to a bottom cylinder position to rapidly expel the trapped fluid into the generator for a surge of steam through the ports.  The ports are preferably so oriented that the iron is operable as a steamer in the vertical position as well as a standard iron in the normal horizontal ironing position.

Abstract: TACHOMETER WITHOUT PHYSICAL CONNECTION     TO INTERNAL COMBUSTION ENGINE   Abstract of the Disclosure A tachometer includes a transducer for sensing pressure variations at the end of the exhaust pipe, or other easily-accessible point, due to explosions in an internal combustion engine.  The transducer produces a corresponding electrical signal having a prominent selected frequency component which varies in frequency in direct proportion with engine speed.  As the engine speed is increased and decreased, the electrical signal is passed through an amplifier with automatic gain control, and through a tracking filter to separate the prominent frequency component from other components.  The separated component may be applied to a frequency-measuring device calibrated to display the revolutions per minute of the engine, or to a computer which computes and displays the result of an acceleration burst test.

Abstract: ABSTRACT OF THE DISCLOSURE            A hitch extends between a towing vehicle such as a tractor, and a trailer includes an upper hitch and a lower hitch together with a releasable latch means holding one against the other.  When released, back up of the towing vehicle and, if necessary, applying the brakes of the trail-er, tilts the trailer rearwardly and continued backing up tilts the trailer over through nearly 180° for full dump-ing.  When the towing vehicle is moved forwardly the trailer returns to the towing position and the latch means may be re-engaged between the upper and lower hitches.  The latch means includes linkage means between a clevis and the lower hitch assembly normally held in the towing position and in engagement with the end of the upper hitch.  It is held in position by means of tension springs.  A cable release moves the clevis after engagement with the end of the upper hitch against pressure of the springs, thus releasing the upper hitch.  A roller in the clevis in conjunction with the end of the upper hitch enables the upper hitch to re-engage the clevis automatically when the trailer returns to the towing position.

Abstract: ABSTRACT             This invention relates to a mechanism for trans-forming rotary into translatory motion, or vice versa.  The mechanism consists of a curve follower which cooperates with a rotary cylindrical curve body in which is designed a curved guide in the shape of a wedge - shaped track in the body, and where the curve follower consists of a towards the centre simi-larly wedge - shaped ring with a larger diameter than that of the curved body.  The ring is located eccentrically in rela-tion to the latter so that the inner edge of the ring meshes with the track as the ring makes out the inner ring of a roller - or ball bearing or is incorporated with such an inner ring as the outer ring or parts connected therewith are retained against rotation in relation to the curved body or vice versa.  The mechanism is characterized in that the outer ring of the bearing has been pivotally mounted about an axis situated in the plane of the bearing in such a manner that the axis mainly goes through the point of engagement and preferably is at right angles to the axis of the curved body.

Abstract: ABSTRACT OF THE DISCLOSURE         The cover of a housing has one or more projections which extend into a slot or respective slots in the main body of the housing.  Each projection is spaced from the walls defining the slot so as to form a passageway from the interior of the housing to the outside.  This passageway is sufficiently long and narrow as to cool burning gases initiated within the housing by an arc, the cooling being sufficient to extinguish the flame before it reaches the exterior of the housing.  The passageways completely encircle the interior compartment of the housing so as to provide sufficient passageway area to relieve the internal pressure caused by an explosion within that compartment sufficiently that plastic can be used for the material of the housing.

Abstract: Abstract of the Disclosure The present invention relates to a process and apparatus for operating an internal combustion engine with a mixture of hydrogen, air, and a hydrocarbon type fuel.  The hydrogen is generated by electrolytic decomposi-tion of water and fed into the intake manifold of the engine where it is subsequently mixed with air and fuel.  The pressure of the hydrogen gas generated acts as a control on the production rate of hydrogen whereby the greater the pressure, the slower the production rate.  An alternator provides current to the hydrogen generator for its operation and also acts to control the production rate of hydrogen since as the engine operates faster, the alternator produces more current and causes the rate of hydrogen production to increase.
