  • Patent number: 4898747
    Abstract: A method for applying rubber-to-metal adhesives to metal parts, such as tubular metal sleeves, employs electrostatic disc-type coaters includes the employment slow solvents which maintain the adhesive in a wet or liquid condition from its atomization at the disc to its deposition on the parts. The adhesives are diluted with a solvent which contains cyclohexanone and petroleum solvents.
    Type: Grant
    Filed: November 21, 1988
    Date of Patent: February 6, 1990
    Assignee: Ken-Koat, Inc.

  • Patent number: 4357528
    Abstract: This machine includes a header card receiving compartment and a plurality of bill receiving compartments and is adapted to reconcile the notes rejected by a high speed counting and sorting machine. The machine includes reconciling means comprising a platen adapted to receive a batch printout sheet from the high speed counting and sorting machine, actuating means for imparting a step in movement to the platen, and operating means operable upon certain header cards being fed into the header card feeding compartment for advancing the platen and the batch printout sheet one step to position the next line of print in alignment for view by the operator.

  • Patent number: 4296708
    Abstract: Metal parts are coated with one or more layers of a solvent-based adhesive using a roller coating procedure. The adhesive solution is transferred from a supply reservoir to the metal part by a natural fiber felt covered roll. The freshly coated part is then dried and the coating and drying procedure repeated until a layer of adhesive of desired thickness is built up. The use of a natural fiber felt covered roll permits uniform transfer and application of the adhesive at efficiencies above 90% (ratio of adhesive on the part to total adhesive used).
