  • Patent number: 4313535
    Abstract: An excited frame, vibratory conveying apparatus is described for efficiently conveying particulate material. The apparatus has an elongated conveying member mounted by beam springs on an excited frame means. The excited frame means has a balanced vibratory drive means for vibrating the excited frame along a line of force that passes through the center of mass of the apparatus and preferably through the center of masses of conveying member and the excited frame means. The ratio of the weight of the conveying member to the weight of the excited frame means should be between 1.5 and 3.5 and preferably between 2.5 and 3.5. Such an arrangement provides for minimum transmission of vibration both horizontal and vertical into the stationary supporting structure and further minimizes rocking motion.

  • Patent number: 4143458
    Abstract: A method of making a thin film magnetic head assembly having a spaced substrate and superstrate with a thin film magnetic transducer mounted therebetween by the steps of positioning at least one spacing member between the substrate and superstrate, placing a quantity of insulating bonding material of selected characteristics adjacent the spaced substrate and superstrate and controllably heating the substrate, superstrate, thin film magnetic transducer and spacing member sub-assembly to a bonding temperature located in a bonding temperature range and maintaining the sub-assembly at a bonding temperature to enable the bonding material to substantially fill the space by capillary action thereby encapsulating the thin film magnetic transducer bonding the substrate, superstrate and thin film magnetic transducer into an integral assembly is shown.

  • Patent number: 4136781
    Abstract: A can sorting apparatus is described for processing over 600 filled metal cans per minute. An infeed conveyor moves alongside a main conveyor in which the main conveyor is moving at a speed greater than the infeed conveyor. A transverse diverter directs the moving cans from the infeed conveyor to the main conveyor causing the cans to be automatically spaced as they move from the infeed conveyor to the main conveyor. The cans move past a sensing station to individually identify the cans and determine which cans are to be separated from the others. An overhead separating conveyor extends across the main conveyor at a separating station. An overhead electromagnet is positioned at the separating station to selectively lift a can from the main conveyor and bias the can upward against the lower flight of the overhead conveyor. The overhead conveyor then directs the lifted can transversely from the single line of filled cans to perform the separation of the cans.

  • Patent number: 4081846
    Abstract: A multi-channel magnetic head-slider assembly having a ceramic member having a bottom slider face which is adapted to ride on a thin fluid film a predetermined distance above a moving media wherein the slider face has a hollowed out, central area having a wedge shaped inner surface formed in the interior of the bottom slider face which defines a first and second parallel planar fluid bearing support rail which extend in spaced parallel alignment along the side of the ceramic member and each of which have one end which terminates in sloped surface defining a leading edge relative to the moving media and each of which terminate in and are integral with a third flat fluid support surface forming a trailing edge which is perpendicular to said first and second fluid bearing support rails and a plurality of magnetic transducers having a preselected gap width and predetermined spacing are mounted on the end of the ceramic member at the trailing edge of the ceramic member with the gap of each head adjacent to and in
