Abstract: In a travelling wire EDM apparatus in which a workpiece is cut by an electrode wire by electrical discharges between the wire and the workpiece, a detector circuit detecting each electrical discharge occuring in each sector along the length of the wire in the machining zone. The information detected by the detector circuit is supplied to a circuit simulating the increase of heat of the wire, and the convection of heat into the ambient and into adjoining wire sectors. A control signal for modifying a machining parameter is supplied when the simulator circuit provides an indication of abnormal heating of the wire in one of the wire sectors. Accidental rupture of the wire is thus avoided while assuring that machining is effected at maximum efficiency.
Abstract: A mute made of a block of sound-deadening thermoplastic elastomer having a longitudinal slot for placing over the top edge and portions of the surface of a string musical instrument bridge. Cut-out portions are provided forming slots for passage over the strings, the end of the cut-out portions or slots following generally the contour of the top edge of the bridge. The mute dampens the bridge vibrations and deadens the sound transmitted from the strings to the musical instrument soundboard via the bridge.
Abstract: The invention is addressed to a degasifier for a liquid separated from a gaseous fluid in a gas/liquid separator, such as a degasifier for removing air in suspension in oil after separating the oil entrained in the compressed air, the oil separated from the compressed air being returned to the air compressor. The oil separated from the compressed air in the gas/liquid separator collects in a sump at the bottom of the separator housing. A vessel is disposed in the sump below the level of the oil in the sump. The vessel is open at its bottom and closed at its top, and is partially filled with the oil in the process of being degasified. The top of the vessel is connected by a conduit to a source of reduced pressure, for example a venturi tube disposed in the inlet to the gas fluid separator. The gas collecting below the top of the vessel, air in the example of application described, is continuously evacuated through the conduit and reinserted into the compressed air flow into the separator.
Abstract: An electronic device controlling the intake manifold heater and priming fluid injection system in diesel engines. The device automatically energizes the intake manifold heater and enables the priming fluid injector in response to electrical signals received from a coolant temperature sensor and a lubricating oil pressure sensor so as to improve cold starting, cold driveability, fuel consumption, gas emissions, and to eliminate white smoke at the exhaust. The device prevents the priming fluid injector from being operated until after the intake manifold heater has cooled to a level preventing ignition of the priming fluid, such as ether, in the intake manifold.
Abstract: Improvement in a hydraulic control apparatus for actuating a remotely located mechanism having a shipping and installation restraining strap for an actuator having a housing and a linearly moveable output member projecting from the front end of the housing, the strap being non-elastic and rupturable and having a part thereof engageable with the free end of the output member and another part projecting rearwardly toward the rear end of the housing, the improvement comprising an elastic anchor arrangement for the restraining strap to allow full extension thereof without rupture thereof, a stop and positioning arrangement for the elastic anchor arrangement which predetermines the retracted position in which the output member is yieldably held, and an override arrangement to selectively debar functioning of the elastic anchor arrangement whenever it is intended to rupture the restraining strap.

Abstract: A fluid separator for separating a liquid, such as an oil mist from a gaseous fluid, such as compressed air, the oil mist having been introduced into the compressed air in a compressor. The separator comprises a coarse separation section provided with an inlet directing the oncoming stream of gaseous fluid upon a surface causing coalescence and condensation of the mist of the liquid upon impact, in the form of droplets flowing by gravity to a sump. The stream of gaseous fluid is caused to flow away from the coarse separation section into a fine purification section in which the stream is passed through a fine filter cartridge, causing final condensation of the liquid and separation from the gaseous fluid. A fluid distributor is located at the inlet of the fine purification section and causes further condensation of the liquid by impact of the stream upon the wall of the fluid distributor.
Abstract: An apparatus and method for separating sheets or plates from a bundle and for placing said sheets or plates spaced-apart on a support rack. The bundle of sheets or plates is inclined to a position causing the sheets or plates to slide relative to each other by gravity and to abut at their lower edge on a substantially horizontal surface. The bundle of sheets or plates is subsequently erected to an approximate vertical position causing the sheets or plates to separate at their bottom. The sheets or plates are then separated at their top by means of a "comb" member, and a rack provided with support and separating pins is lifted into engagement with the bottom of the spaced-apart sheets or plates. The apparatus may be used in reverse for rebundling spaced-apart sheets or plates.
Abstract: A stop-leak sealant composition for an internal combustion engine cooling system, hot water heating systems and the like consisting essentially of ginger rhizome flour, ground nut shells, boric acid, with or without additives to improve performance and more particularly with a fluorescent water-soluble leak detectng additive to detect leaks that cannot be stopped by the sealant composition.
Abstract: In a travelling wire EDM apparatus for effecting a cut by electrical discharges on a workpiece blank by an electrode wire, the workpiece blank is supported by two support members mounted on a rotary table, one support member being disposed in the interior of the perimeter of the cutting path and the other support member being disposed exteriorly to the perimeter of the cutting path such as to support the two portions of the workpiece blank severed from each other during the cutting operation. A partial cut is first effected through the workpiece blank and the workpiece blank is subsequently angularly oriented to a different position by rotating the rotary table such that collision between any one of the electrode wire support arms and the workpiece blank support member disposed within the perimeter of the cutting path is prevented.
Abstract: An arrangement for applying an electromagnetic force on the electrode wire of a travelling wire EDM apparatus by passing through the workpiece an auxiliary current parallel to the current flowing through the electrode wire, in one direction or the other. The points of application of the auxiliary current on the surface of the workpiece are disposed opposite to the front of a cut relative to the electrode wire in order to obtain a resultant force which either pulls the electrode wire away from the front of the cut or draws it closer to the front of the cut.
Abstract: The portable refillable inflator for air mattresses, inflatable balls, pneumatic tires and the like, in the form of a tubular vessel provided at each end with an inverted domed wall. One wall is provided with a conventional tire inflation valve for filling the vessel with compressed air, and the other domed wall is provided, with an outlet valved nozzle having a flexible tubular body through which extends a stem attached to a disk disposed within the vessel and normally fitting against an annular seat. Upon deflection of the flexible nozzle body, lateral displacement of the stem causes the valve disk to uncover a portion of the seat thus permitting air to escape from the vessel through the outlet nozzle.
Abstract: In a travelling wire EDM apparatus the thermal stresses of the electrode wire are substantially reduced by detecting the position of the triggering electrical discharges preceding the machining electrical discharges, and by controlling the supply of the machining electrical discharge current at one end of the machining zone, at the other end of the machining zone or at both ends of the machining zone. When a machining electrical discharge is located between one end of the machining zone and a first reference position, the machining current is applied at that end. When the electrical discharge is located between the other end of the machining zone and a second reference position, machining current is supplied at that second end. When the electrical discharge is located between the two reference positions, the machining current is applied simultaneously at both ends of the machining zone.
Abstract: A method and apparatus for threading the electrode wire of a travelling wire EDM apparatus through an aperture in a workpiece. Prior to automatically threading the wire through the aperture in the workpiece, the wire is continuously straightened by pulling longitudinally on the wire, and the wire is passed through a guide tube and through a nozzle to which fluid under pressure is supplied for forming a jet stream at the outlet of the nozzle. Prior to a threading or rethreading operation the wire is cut off proximate to the outlet of the nozzle. The nozzle outlet is brought in close proximity to the aperture in the workpiece and the jet stream is aimed at the aperture in the workpiece for guiding the wire through the aperture, while being maintained coaxially by the jet stream.
Abstract: An EDM electrode wire changer has a plurality of conduits, one for each available electrode wire, all conduits converging towards the threading axis of a selected electrode wire through the workpiece or, alternatively, disposed substantially parallel on a slide that is indexable such as to dispose the outlet of a selected one of the conduits in alignment with the threading axis. A common motor-driven threading roller is disposed proximate the inlet of the conduits in a stationary position relative to the conduits, and a pinch roller for each wire co-operates with the threading roller for feeding the selected one of the wires through its corresponding conduit by forcing the selected wire against the peripheral surface of the common threading roller, while the other pinch rollers are remaining in a position away from the threading roller.
Abstract: A motor vehicle steering knuckle and kingpin assembly comprising a kingpin fixedly mounted through the motor vehicle front axle or beam with the end portions of the kingpin projecting above and below the front axle or beam. A wheel spindle knuckle is pivotally mounted relative to the kingpin, the spindle knuckle having an upper yoke having a bore disposed around the kingpin upper end portion and a lower yoke having a bore disposed around the kingpin lower end portion, a bushing being installed in each of the yoke bores. The kingpin end portions have a frusto-conical peripheral surface and the yoke bushings have a cylindrical internal surface such that, under load, the bearing surfaces in engagement and capable of transmitting the load are along the whole length of the bearing surfaces. Alternatively, the kingpin end portions are provided with a peripheral cylindrical surface co-operating with an appropriate frusto-conical internal surface for the bushings.
Abstract: A beverage container lid made of relatively thin, flexible and sound resounding material, provided with cross-slits at its center with a sound reading member in the form of a sharp projection engageable with an in-depth recording soundtrack linearly embossed on the peripheral surface of a coacting drinking straw. By pushing the drinking straw through the cross-slits in the lid, the sharp projection engages the linear soundtrack on the straw thus causing the lid to vibrate and emit a sound corresponding to that recorded on the straw soundtrack.
Abstract: In certain motor vehicles having six cylinder internal combustion engines, the excessive use of lubricating oil after the vehicle has been driven 50,000 miles is stopped by inserting a drive rivet into the radial oil passageway in the intake valve rocker arms; such passageway connecting with an internal lubricating oil groove in the rocker arm.
Abstract: A hot water distribution system for providing almost instantaneous supply of hot water at a hot water usage outlet. The system of the invention comprises a closed loop and a pump circulating hot water in the closed loop from a supply of hot water and back to the supply of hot water. One or more usage outlets are connected to the closed loop each by a relatively short length of pipe. A one-way check valve prevents drawing water from the return line of the closed loop. Heat insulation of the closed loop is provided to prevent unnecessary heat losses, and a thermally operated switch may be used to control the operation of the closed loop circulation pump to maintain the water in the closed loop at a predetermined temperature.
