    摘要： A plurality of circuit boards having male pin connectors are connected to a mother board having female pin receptor connectors, each circuit board being supported by a pair of grooved edge guide means. After the circuit boards are inserted into the device, a cover having a resilient foam pad on the inside surface thereof is closed wherein the foam pad resiliently presses against the upper edges of the circuit boards to hold them into position and maintain good electrical integrity with respect to the aforesaid connectors at the bottom portions of the circuit boards. Edge connectors may be plugged into the sides of the boards for further electrical access, and the heights of the edge guide means are high enough so that lower portions of the edge connectors are blocked and held in position by upper portions of the edge guides to prevent the edge connectors from being dislodged or loosened from the sides of the circuit boards.

    摘要： An optical sensor is positioned at the output of a variable magnification optical system which focuses differing character size images upon a photosensitive medium. A reference voltage, which is a function of the proper exposure for a particular photosensitive medium, is compared with the photosensor voltage. The system automatically tests for the correct light flux before each size change by projecting a reference image through the optical system at the photosensor, such image having a relatively low intensity level, so that no output signal is produced by the above-mentioned comparator. The intensity of the reference image is iteratively increased until such output signal is produced by the comparator, thereby to maintain the light intensity at the last level attained, until a character size change is effected, wherein the comparison process is repeated. Upon the substitution of another photosensitive medium having a different sensitivity, the comparator threshold voltage is altered accordingly to produce the proper illumination intensities for various character sizes tailored to the sensitivity of the second photosensitive medium.

    摘要： A brake mounted upon a moveable phototypesetter lens carriage is in continuous braking contact with a stationary flat elongated way member positioned along the path of motion of the carriage. A central portion of a brake shoe member is rigidly affixed to the moveable carriage and has first and second flexible arm members spring biased against the way member, and the entire brake shoe member consists of a single homogeneous mass of material.

    摘要： A plurality of outwardly and radially extending font segment support arms are coupled to a central hub which is rotated to sequentially present the letters formed upon the segments to an optical imaging station which selectively projects optical images of the letters upon a photosensitive medium. Vertical shoulder portions are precision machined upon outer portions of the radially extending support members for precisely positioning the arcuate character tracks on the segments with respect to the imaging station. Horizontal plates are affixed to the radially extending support members to support the segments against gravity and centrifugal force is employed to precisely seat the segments against the vertically oriented shoulder portions upon rotation of the hub.

Vertical shoulder portions are precision machined upon outer portions of the radially extending support members for precisely positioning the arcuate character tracks on the segments with respect to the imaging station. Horizontal plates are affixed to the radially extending support members to support the segments against gravity and centrifugal force is employed to precisely seat the segments against the vertically oriented shoulder portions upon rotation of the hub. A stationary stage plate together with a ramp element provide for easy and rapid insertion and removal of font segments from the front of the phototypesetter.

    摘要： Wire for repairing or changing circuit elements such as printed circuits has heat-resistant insulation surrounded by a hot-melt adhesive. The wire is attached to the surfaces of printed circuit boards easily by applying a hot iron to the adhesive layer on the wire and melting the adhesive which then adheres to the board surface. The hot iron has a tip with a groove in it so that when the iron tip is pressed onto the wire, the tip embraces the wire to melt the adhesive quickly and to make the bond relatively quickly. The coating is applied by passing insulated wire vertically through a length of molten adhesive and then through a die. A cleaner/holder device is used for cleaning the tip of a hot iron used for melting adhesive, or a soldering iron, and for holding the hot iron when it is not in use. The preferred cleaner is anti-combustion treated absorbent cotton string wound on a spool which is mounted in the holder, or adhesive tape with a soft clutch backing. A fresh cleaning surface can be provided simply by rotating the spool, or unwinding a layer of the cleaning material and removing it.
