  • Cropping mechanism for surface mount placement machine
    Patent number: 5125307
    Abstract: A cropping mechanism for a surface mount machine is disclosed which cuts the feed tape supplying electronic components. The displacement of an actuator in one direction between end positions cycles the cropping blade from a start location to the cutting location and back to the start location. The actuator has a cam which rides in selectively configured slots defined in opposed, pivotally supported levers which support a pin received by the cutting element and controlling its displacement.

  • Glassware making machine
    Patent number: 5122179
    Abstract: An H-28 machine is a glassware making machine having a plurality of glass making sections which rotate about a vertical axle. The complete process takes one revolution. Individual section mechanisms are controlled by electronically setable cams on a central timing drum and whenever two mechanisms sequentially occupy the same space in a section, machine speed is determined and the cam settings are checked to make certain that the mechanisms will not interfere.

  • Blind fastener
    Patent number: 5120169
    Abstract: A blind insert having a compressible plastic bushing having a flange at one end which merges into a first cylindrical portion and a second reduced diameter cylindrical portion at the other end. A metallic end cap is secured on the free end of the plastic bushing and is spaced from the first cylindrical portion and the dimension of the first and second cylindrical portions are selected so that as a screw is inserted into the fastener the first cylindrical portion will bulge outwardly and rearwardly to extend over the open end of the cap to forcefully center the cap to prevent tearing of the bushing.

  • Linear energy communicator
    Patent number: 5113962
    Abstract: A linear energy communication system which allows a stationary device to communicate with a device moving along a predefined path through the use of radiated energy. An electronic signal generated by a transmitter is converted into energy in the opto-electromagnetic frequency spectrum by means of an appropriate transducer. The energy is then focused into a line. A receiving device moving along the path of the line receives the linear energy and converts the received energy back into the original electronic signal. The system will allow for the communication and guidance of a remote moving vehicle along a predefined path without the encumbrance of wires, buss bars or broad band communications.

  • Metal weld stud and plastic clip
    Patent number: 5111557
    Abstract: The combination of a metal stud having a projecting head for welding to a receptor surface and a resilient clip for mounting on said stud and retained by said projecting head is characterized in that the underside of said head has a tapered shoulder which reduces progressively to the diameter of said stud, in that said clip has a retaining hole of which the internal diameter increases correspondingly from a diameter equal to that of the stud whereby it engages the tapered shoulder under said head when the clip is applied to the stud and in that said clip is provided with at least two retaining members which contact said receptor surface to urge the clip into close engagement with the tapered shoulder under the head of the stud.The clip is easily mounted on the stud by direct pressure and provides a more positive location of the clip on the stud.

  • H-28 machine having an adjustable neck ring lever
    Patent number: 5110339
    Abstract: A neck ring mechanism of an H-28 glass forming machine is operated by a neck ring lever which is pivotally supported and controlled by a cam roller which is displaced along a timing cam. To precisely define the timing of the lever, the lever is displaceable relative to a sleeve which is secured to the shaft and a control knob operating through an adjuster plate assembly adjusts the axial location of the lever.
