Abstract: An improved score or perforator bar device is adapted for use with certain printing presses having a blanket cylinder revolving upon an axle shaft and with an elongate slot for attachment of the blanket. The adapter device includes a bar of a length substantially the same as the cylinder with a working side having a longitudinal slot for mounting a knife blade. The knife blade has either a scoring edge or a perforation edge, depending upon the desired effect. The bar has an attachment side for connection to the blanket cylinder and has legs extending generally perpendicularly. The legs have recessed ends for bearing against the cylinder shaft so that the force of the blade is transferred to the axle shaft and not to the cylinder shell. Hooks selectively extend about the cylinder shaft. A screw arrangement retains the bar in a cylinder slot. A numbering device in lieu of the knife blade can be retained within the longitudinal slot.

Abstract: A switch probe, generally for use in testing cable harnesses, is for placement within a standard probe receptacle and can be removed and replaced as necessary.

A conductive second switch portion is received within the barrel and has an engagement tip positioned forwardly of the barrel open end for electrical contact with a test site. A second shaft extends rearwardly and into axially spaced relation to the first shaft. An elongate hollow insulator extends fully between and provides a guideway for reciprocatory contact between the first and second shafts and fully shields the second shaft from electrical leakage prior to conductive contact of the second shaft with the first shaft.

Abstract: A module attachment for testing a linear high density array of test sites on a printed circuit board having such circuit test sites where an integrated circuit chip (IC) is to be mounted. Present IC's may have wire lead spacings as close as 0.010 inch with integrated chip development utilizing even more compact and close center pad spacing, such as 0.004 inch. This spacing is too close to use even the thinnest of spring contact probes. The module carries an array of densely packed thin wires embedded in a small matrix block mounted on spaced supports, which may be conventional, large diameter spring contact probes. Electrical connection to the array of wires in the module is done by each wire being connected to a separate wire lead with the wires bundled and routed to a test computer. In its closest wire spacings, the module permits testing of the densest IC's and in wider spacings, provides a low cost alternative to spring contact probes.
