A memory which contains external contacts and is capable of counting and storing values is provided from which base units can be subtracted by the control unit of the machine depending on the amount of ribbon advanced. The novel ribbon cassette makes it possible to dependably determine and display either the amount of ribbon remaining or the end of the ribbon.

Abstract: In a dot matrix line printer in which a plurality of hammer springs mounted along the length of an elongated reciprocating hammerbank are selectively released or fired to impact dot printing impact tips mounted thereon against a print paper through a length of ink ribbon to print dots, the wear that would otherwise occur each time one of the hammer springs rebounds back into contact with a pair of pole pieces against which the hammer spring resides when in its retracted position is greatly minimized by chromium masses plated on the tip of the hammer spring and on the tips of the pole pieces. Chromium platings on each hammer spring are confined to the end of the spring and comprise either a pair of masses adjacent the different pole tips or a single mass encompassing both pole tips. The chromium masses are of convex contour and of hexavalent chromium composition to provide the masses with hard and smooth surfaces that slide over and do not abrade one another upon impacting.

Abstract: A function for an electronic typewriter is described which allows the operator of the typewriter to realign the print element of the typewriter to the prior adjacent, or the following adjacent line which contains textual material, even when the present position of the print element is other than a uniform line feed increment or multiple thereof, from the designated destination line. The electronic controls of the typewriter determine the present position of the print element and the vertical location of the line to which the print element is to move, and determines the distance and moves the record sheet to position the print element precisely over the designated line of text.

Abstract: A switchable printing couple particularly suited for use in newspaper and periodical printing is disclosed. A counter pressure cylinder and plate cylinder cooperate to print a moving paper web. An ink fountain, which does not require ink keys, supplies ink to a hard surfaced screen roller. Ink from the screen roller is transferred either directly to an elastic flexographic printing plate or indirectly through ink cylinders to a hard letterpress printing plate. The screen roller which dips into an ink fountain and from which excess ink can be removed by use of a doctor blade, is capable of being engaged with and lifted off the plate cylinder so that the printing couple can be used either in direct printing with an elastic flexographic printing plate or in indirect printing with a hard letterpress printing plate.

Abstract: A thermal printer includes a single thermal recording medium interposed between printing paper and a thermal head so that when predetermined energy is applied to the thermal head, colorant on the thermal recording medium is transferred to the paper to print out a desired letter or symbol, or alternatively the printed letter or symbol is removed and erased from the paper because the colorant once transferred to the paper is attached to the colorant on the thermal recording medium. A printing method using the thermal printer is characterized in originally setting printing energy and erasing energy the latter of which is equal to or larger than the former, applying the printing energy to the thermal recording medium to effect printing operation, and applying the erasing energy to the thermal recording medium to attach it to the printed letter or symbol on the paper to remove and erase it from the paper.

Abstract: A recording head of a current application type serial printer is provided with two independent recording electrode groups on both sides of its tip. The angle of contact of the recording head with a platen of the printer is switched between a forward printing stroke and a backward printing stroke of a carrier so that, usually, the electrode group on the right-hand side of the recording head is used during the forward printing stroke, and the electrode group on the left-hand side during the backward printing stroke.

Abstract: A hybrid composite material is constructed from woven reinforced fabrics of Kevlar 49 and biaxially reinforced fibers of graphite and E-Glass bonded together with a thermosetting adhesive, for the application of custom orthotics. The material is designed with the idea of introducing different fibers at different locations of the orthotic in order to take advantage of the unique properties of each reinforcing fibers. The resulting material creates a hybrid composite that exhibits a balance of properties, in both the longitudinal and tranverse directions, unavailable with any single reinforcing fibers. A method of orthotic manufacturing involves a hand lay-up and forming procedure. The constructed composite material is formed and pressed on a prescribed cast, then allowed to cure under pressure. The post-cured material is stripped from the cast, then cut and ground and finally finished to the required orthotic.
