Abstract: Abstract of the Disclosure A method and machine for applying a configura-tion of reinforcement/stiffening or decorative material in powder form to a receiving surface, for subsequent fusing, cooling and pressing to a substrate such as a shoe upper.  The machine comprises a deposition sta-tion, a heating station and a press station.  A ten-sioned receiving belt receives the configuration of powder through a cut-out in the bottom of a swept screen frame.  The receiving belt is supported from beneath during the deposition activity to control the thickness of the powder deposit.  The receiving belt is shuttled in a displaceable frame in a series of steps to the successive stations for melting the powder and subse-quent cooling and adhesion of the melted powder to the substrate such as an unreinforced shoe upper.          The cut-out may have a peripheral gasket arranged partially therearound to displace  at least a part of said cut-out from said receiving surface, leaving sufficient volume therebetween for filling by the pow-der as a three-dimensional (tapered) configuration.

Abstract: ABSTRACT OF THE DISCLOSURE        A rectangular wafer thermistor comprises a piece of ceramic thermistor material having electric contact material covering its opposite surfaces.  A contact defining score mark with an open geometric shape other than a straight line extends across the thermistor through one layer of the con-tact material for separating the contact material on that surface into two contacts.  The ends of the contact defining score mark intersect the opposite edges of the thermistor at different locations along the thermistor.  The contact defin-ing score marks may be V or U or otherwise shaped, and the intersections between the different sections of these score marks are preferably rounded, but may be sharp corners.  The shape of the contact defining score mark prevents the ther-mistor from breaking at the contact defining score mark when the thermistor is broken off a large sheet of thermistor material.  A sheet of ceramic thermistor material, coated on its opposite surfaces with contact material, has a grid of thermistor defining score marks defined in one surface, and the sections of the sheet surrounded by the grid lines form individual thermistors.  A bending moment of force applied to the sheet will break the sheet along the thermistor de-fining score marks, but the geometric shape of the contact defining score mark in each thermistor will prevent the thermistor from breaking on the contact defining score mark.

Abstract: ABSTRACT OF THE DISCLOSURE   ELECTROMAGNETIC INTERFERENCE SUPPRESSION FOR                ELECTRICAL DISCHARGE PRINTERS     Disclosed is a system and method for reducing the level of electromagnetic emissions radiated by electrical discharge type printers.  Such printers utilize one or more styluses which are scanned across the width of a roll of electrosensitive paper and are selectively energized to vaporize small areas on the paper's coating to thereby form characters.  When the coating vaporizes, a spark is produced which generates a broad band of electromagnetic energy which is conducted into the environment due to the conductive coating of the previously printed paper acting as an antenna.         In order to reduce the effective antenna length and/or propagation capability to thereby reduce the energy radiated, the present system creates isolation bands at preset intervals as the printing occurs.  The isolation bands are produced by continuously energizing all styluses as they scan across the full width of the paper, thereby causing an entire band of the paper's conductive coating to be burned off across the entire width of the paper.  Each isolation band severs the conductive surface of the paper, thereby reducing the effective length and/or propagation capability of the antenna created by the printed paper and lowering the level of radiated energy.
