One of the crenellated rims has a peripheral groove in which is disposed an expandable resilient ring, and the other crenellated rim has a corresponding peripheral groove and is provided at the leading edge of its projecting portion with a ramp for expanding the ring when the one of the crenellated rims is pushed into the other crenellated rim for coupling the bearing carrier with the tubular member during assembly of the bearing carrier with the tubular member.

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: 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: 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 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: A method and apparatus for polishing a workpiece by electrical discharges by way of an electrode tool, machining pulses of relatively low power being obtained from a machining pulse generator. A cross-slide table provides the workpiece with a translation cyclical motion during polishing. Input control circuits enable the machine operator to program a chosen speed of translation for the cyclical motion, the radius of circular translation and the time of duration of machining. A counter counts the number of cycles being effected and a discriminator stops the pulse generator as soon as the chosen number of desirable cycles is obtained, such number being inversely proportional to the amplitude chosen for the translation motion.

Abstract: An electrical switch for sensing operation of a hydraulic cylinder, the switch being normally open and closing an electrical circuit when the cylinder is pressurized to effect a desired operation only when there is fluid at a predetermined pressure in the cylinder. The hydraulic cylinder is the slave cylinder of a motor vehicle clutch hydraulic control and the electrical circuit controlled by the switch is, for example, the motor vehicle engine starter motor relay circuit, such that the starter relay circuit is inhibited unless sufficient pressure is present in the cylinder, corresponding to the pressure necessary to cause the slave cylinder output member to fully release the clutch.

Abstract: An interlock switch mounted in the end of a hydraulic slave cylinder adapted to operate the release mechanism of a motor vehicle mechanical clutch, the slave cylinder being hydraulically connected to a master cylinder having an input member operable by the motor vehicle clutch pedal. The switch is adapted to close the motor vehicle starter relay circuit for a position of the slave cylinder output member corresponding to full release of the clutch, such that the clutch must be fully released in order to allow starting the motor vehicle engine. Preferably, the switch takes the form of a pair of concentric sleeves, each carrying appropriate contacts for closing the circuit, one of the sleeves being reciprocable in unison with the slave cylinder output member, and the other sleeve being automatically adjustable for initial position adjustment and for subsequent readjustment to compensate for wear of the clutch, such that closure of the switch always corresponds to a full release of the motor vehicle clutch.

Abstract: A bearing assembly having bearing surfaces pre-loaded towards each other, the bearing surfaces being originally made in slightly non-conforming geometry and dimensions over the majority of their surface areas in sliding engagement, the areas of the bearing surfaces in engagement being thus less than the total available areas. During use, and through progressive wear-in of the bearing surfaces in engagement, the bearing surface areas in engagement are progressively enlarged with progressive conformity in geometry and dimension, the conforming surface areas being constantly kept in engagement by the elements in the assembly adapted to provide bearing pre-load.

The top of the bracket or clip is provided with an angularly inwardly projecting integral portion terminating in a slightly downwardly bent flange forming a hook. The clamp is used principally for holding a sink bowl, or the like, in an opening in a counter top by cooperating with a generally L-shaped angle-iron strip welded to the underneath of the sink bowl flange. For removably holding the sink bowl in the opening in the counter top, the hook end of the clamp bracket body is engaged behind an inwardly bent flange portion of the angle-iron strip and the threaded member is tightened against the lower surface of the counter top proximate the opening.

Abstract: A travelling wire EDM apparatus wherein a workpiece is cut by electrical discharges by a travelling wire electrode, relative motion of the workpiece and the wire electrode being controlled by a numerical control unit which, in addition, controls transverse oscillations of the electrode wire relative to the workpiece along the cutting path. The energy of the electrical discharges is varied as a function of the amplitude of the transverse oscillations of the electrode wire relative to the workpiece such as to obtain maximum electrical discharge energy when the amplitude of vibration of the electrode wire is at a minimum and minimum energy when the amplitude of vibration of the electrode wire is at a maximum.

Abstract: An apparatus and method for transferring parts travelling in a single row on a first conveyor to a receptacle travelling on a second conveyor, the parts being placed in the receptacle in consecutive rows of a plurality of the parts. A part loader, comprising an elbow-joint arm having a pivotable first arm and a second arm mounted on the end of the first arm pivotable relative to the first arm, supports a part pick-up member mounted on the end of the second arm which picks up a row of parts from the end of the first conveyor and transfers the parts to the receptacle on the second conveyor. The part pick-up member is adapted to pick up a row of parts from the first conveyor and to place the row of parts in the part receptacle in the same position, or to rotate the parts about 90.degree. or 270.degree. during transfer from the first conveyor to the part receptacle on the second conveyor.

Abstract: An apparatus and method for displacing a linear output member by wrapping at least a pair of flexible strands around the periphery of the linear member. The flexible strands are each attached at each end to spaced-apart rotatable members. Rotation of the rotatable members in opposite direction causes engagement of the flexible strands with the linear member as a wrap around the periphery of the linear member. After a grip is effected on the linear member, rotation of the rotatable members in the same direction causes the linear member to be linearly displaced.
