Patent CA-1118071-A (CA)
Inventor: BOBICK THOMAS W
IPC: H03K17/96
Filed: 1977-10-25
Granted: 1982-02-09
Abstract: ABSTRACT OF THE DISCLOSURE A human touch on an etched copper electrode produces a capacitive change to vary the time constant of an RC network as a part of an oscillator.  The variation in the capacitance of the sensor changes the time constant of the RC network which results in a change in frequency of the output signal of the oscillator.  This change in frequency thus varies with the human touch to the copper electrode.  To develop a directional indication of the touch position, four electrodes are arranged in opposed pairs along orthogonal axes.  Each electrode is part of an RC network connected to an oscillator with each of the four oscillators identified with one of the four positions along the orthogonal axes.  The output signal from each of the oscillators is transmitted to timing and control circuitry that generates four separate pulse trains, one pulse train identified with each of four positions along the orthogonal axis.

Abstract: ELECTROCHEMICAL CELL HAVING ENHANCED-SURFACE NON-CONDUCTING SOLID ELECTROLYTE         AND METHOD OF MAKING SAME                        ABSTRACT           A layer of porous ion-conducting solid electrolyte material is applied to a dense substrate of the same material and then coated with a catalytic electrode to provide additional surface area in ionic continuity with the conduction paths for ion transport in the bulk lattice.  For a yttria stabilized zirconia electrolyte, the enhanced surface area results in an oxygen sensing cell of a particular dimension having a much lower output impedance than a similarly dimensioned cell having only a dense electrolyte.  Furthermore, the improved cell can operate at much lower temperatures than prior art cells.  The catalytically coated porous high surface area electrolyte coating provides, in an automotive oxygen sensor, a dual function.  Firstly, it provides a catalyst support in its outer extremities to provide thermodynamic equilibrium to the exhaust gases. Secondly, it provides reactivity deep in the matrix of the coating between oxygen ions and the thermodynamically equilibrated gases.  Further, a method is disclosed for lowering the output impedance of an electrochemical cell having a dense substrate of an ion-conducting solid electrolyte which is of a predetermined thickness.  The invention would also be useful for fuel cells.

Abstract: LONG FOLD SUPPORT STRUCTURE FOR     ZIGZAG WEB-FED FOLDER                   ABSTRACT OF THE DISCLOSURE            An improved spiral-type zigzag web folding unit is provided which includes an inexpensive, replaceable, constant tension recoil spring coupled to the shiftable web feeder chute of the folding unit for individually and successively supporting relatively long web sections as they are fed, in order to prevent excessive gravity-induced sagging thereof and consequent failure of the spirals to engage and receive the fed sections.  Use of an oscillating recoil spring permits high-speed folding operations with automatically timed support for the web sections, notwithstanding the fact that the spring requires no adjustment in use and can be easily installed and replaced using readily available materials and tools.  Furthermore, coupling of the spring to the feeding chute ensures that the spring does not impede web feeding but rather moves in timed relationship therewith for support purposes.  The support spring assembly hereof is also advantageous in that inertia problems are minimized and support is provided along a substantial portion of the web sections in timed relation to the feeding thereof.

Abstract: PIVOTING BLADE EXTENSION FOR A VERTICAL MIXER  Abstract of the Disclosure An improved mixing blade assembly is disclosed that reduces torque requirements and impact loading in a mixer.  The assembly is particularly useful in conjunction with a mixer-grinder having an upright cylindrical tank with a substantially flat bottom and centrally located vertical mixing auger.  The assembly includes a blade mounted on the auger for rotation therewith.          The blade is generally parallel to and spaced above the floor and terminates inwardly from the tank wall so coarse material can slide off its end.  The floor-to-blade spacing eliminates shear forces and impact loads that would otherwise occur as the blade sweeps over openings in the tank bottom.  An extension member is pivotally connected to the blade about a vertical axis and is freely swingable between the blade and the floor.  The extension member extends radially outwardly by centrifugal force to sweep close to the floor near the tank wall as the tank empties.  When the tank is full, the member trails behind the blade to avoid packed material near the outside of the tank.

Abstract: ABSTRACT         The printer is provided with a single tracing element for tracing characters under the control of stored digital instructions corresponding to a set of segments of the character.  The tracing element is moved on the printing surface according to a pair of coordinates, within the limits of each character.  To this end it is carried by a frame including a pair of hinged elements directed according to the two coordinates and moved by a pair of electromagnets.  These latter are controlled by feed back circuits including a pair of position  sensors.          The frame is mounted on a carriage transversely movable according to other instruction for letter spacing.  A movement of the printing element according to a third coordinate causes the tracing element to press the paper with a pressure corresponding to the thickness of the sign.          The instructions of each segment include the speed of the tracing element along the two coordinates, whereby by altering either the time interval of operation or the amplitude of signals, the character can be altered in sizes along one or two coordinates.  The instructions of one or more alphabets or type fonts are stored in a pluggable ROM addressable by input signals.  The printer is particularly adapted for electronic typewriters, word processing apparatus, as well as for running hand and ideographic characters, for example, characters of Arabic, Urdu, Chinese, Kanji, etc. languages.
