Abstract: A document imprinter, especially for labels, tickets, tags, and the like, having an elastomeric platen with an outermost thin sleeve which is harder than the underlying platen material thereby resulting in sharper printing. The sleeve is preferably of a material which is smooth and glossy and non-adherent to adhesives, thus minimizing undesired transfer to the platen of adhesive from the web to be imprinted.

Abstract: An analog to digital wave shaping system comprising, a source of analog signals, adaptive threshold circuitry coupled to said source, said adaptive threshold circuitry having an output selected as a function of the intensity of said analog signal compared to a fixed intensity signal, and, comparator circuitry coupled to said source and to the output of said adaptive threshold circuitry.

Abstract: A baud or repetition rate generator for providing required clock rates from a oscillator utilizing a commonly available crystal by counting to an integer, N, a number of times, m, and then counting to N+1 the remaining number of times, n, within a cycle having (m+n) parts, and providing an output pulse after each count of N and N+1.

Abstract: A symbol decoding system for decoding symbols comprised of plurality of bars some of which representing characters, comprising, means for providing a series of pulses representative of said bars, means for counting the interval between positive transitions between adjacent pulses, means for counting the interval between negative transitions between adjacent pulses, means for storing said counted intervals, means for testing for certain predetermined relationships among said counted intervals, and means identifying particular characters whenever said predetermined relationships are satisfied.

Abstract: An article of seating comprises a shell member and a skin member in contact with the shell member, the skin member being attached to the shell member throughout substantially the entire surface area of mutual contact between the skin member and the shell member.

Abstract: A digital circuit and method for measuring magnetic tape skew of magnetic tape units by recording on two channels of a reference tape a digital bit pattern of alternate pairs of zeros and ones.Digital logic circuitry, which detects this information on a reference tape when read from a magnetic tape unit to be tested, feeds the digital information on one channel to a shift register which is sampled by a clocking signal derived from the other channel. The digital bit pattern indicated at the output stages of the shift register will identify the existance of any excessive lag or lead skew.

Abstract: A manually actuable keyboard switch is provided having two opposite relieved openings in its base portion so that when it is inserted into an aperture in a keyboard switch retainer having two tabs outwardly extending and depending from opposite sidewalls of the aperture, the tabs spring into their original positions and within said relieved openings to hold said keyboard switch therein.

Abstract: A phase-locked loop circuit for use in a printer which automatically compensates for speed changes in the print head due to changes in line frequency to maintain consistent character width print impressions.

Abstract: A storage unit divided into a plurality of stations, is rotatable about a vertical axis to allow any given station to be turned to a position where the articles at that station can be retrieved. A control circuit is provided to allow an operator to select a station, provide an input indicative of that selection, and have the unit rotate through the shortest distance to provide access to the selected station.

Abstract: A heat and pressure consolidated laminate in which the back most sheet has fused thereto a surface film composition of polyvinyl alcohol, animal glue or starch which serves a glue line to which conventional glues adhere, the film being adhered to the back most sheet during heat pressure consolidation of the laminate by transferring the same from a release layer to the back most surface of the laminate and fusing the transferred film to the thermosetting resin impregnated in the back sheet.

Abstract: A document imprinter, especially for labels, tickets, tags, and the like, including a rotary printing unit having several banks of printing means and corresponding respective setting mechanisms therefor the latter including viewing windows arranged so that the various windows for the different banks of printing wheels are all readable by the operator in a single angular home position of the rotary printing unit.

Abstract: A hanger bracket adapted to secure wire merchandise hangers to perforated board is disclosed. The bracket has a plurality of communicating vertical and horizontal channels which enable it to accommodate hangers of various diameters.

Abstract: Hot printing of hard copy i.e., human readable, characters to meet the strict, high quality dimensional and other standards required for automatic optical or other means of reading such characters. The printing is effected by a heat responsive ink means. In the present embodiment, the ink means is heated by the printing members.Documents, especially tags or labels, marked with such hot printed automatically readable characters. The documents may also contain punched encoded information; and may further have printed thereon conventional, human but not automatically readable characters.

Abstract: A document imprinter, especially for labels, tickets, tags, and the like, having a rotary printing unit and an inking roller, with novel means for adjusting the position of the inking roller relative to the printing unit, said adjusting means including locating means in the form of a plurality of flat surfaces each located at a different distance from the roller's axis of rotation.

Abstract: A portable calculator utilizing a solar panel array which can be either slidably moved within the calculator's housing or pivotly connected to it and which when exposed to incident light provide power for the calculator.

Abstract: A constant potential power supply with current overload protection having a series switching regulator including a series switching circuit controlled by both a Schmitt-trigger circuit controlled by an output voltage detector to maintain the output load voltage within a predetermined range during normal operation and a current overload protection circuit having a foldback characteristic which operates when the output current goes above a predetermined value. The Schmitt-trigger circuit is actuated by a signal from an output voltage detection circuit when the output load potential decreases below a certain value to enable the series switching circuit to conduct current to the load from an input voltage source and is disabled as the output load potential goes above a certain value. After actuation of the series switching circuit and until it is disabled, charging current passes into an integrating capacitor.

Abstract: A document imprinter, especially for labels, tickets, tags, and the like, having a rotary printing unit and an inking roller therefor, having a novel means for driving the inking roller at a constant rotational ratio relative to the rotary printing unit even though the distance between the two is changed, said novel means comprising a deformable cup-shaped member.

Abstract: An optical scanning station includes means for generating a predetermined scanning pattern along a given plane, and a member embodying said scanning pattern in the form of open slots substantially coincident with said given plane.
