Abstract: ABSTRACT           It has been found that the origin of crack(s) in the Ta2O5 anti-abrasion layer of a thermal printing head results from the crystallization of Ta2O5 in the layer, and that the crystallization can be suppressed by an addition of SiO2 to the layer.  Thus, the anti-abrasion layer is kept from the crack(s) even under the high speed printing conditions using pulse width of 1 ms or less, and also under high colour density printing requiring input power density like 50 mj/mm2.  Also, the thermal wearing life of the printing head can be extended to more than 10 folds of a conventional thermal printing head employing pure Ta2O5 anti-abrasion layer.  The thermal printing head is subject to an appropriate annealing to stabilize the resistivity of the heat elements.  The anti-abrasion layer is provided in a uniform mixture of Ta2O5 and SiO2 throughout the layer by sputtering a target composed of a mixture containing tantalum and silicon ingredients.

Abstract: "Error Correction Apparatus Using a Viterbi Decoder"     ABSTRACT     In an error correcting apparatus, an add-compare-select circuit is provided for each state in a given time slot of a Viterbi trellis diagram.  The ACS circuit includes first and second pairs of adders coupled to a source of sequentially updated path metrics and to a branch metric generator which generates sums of branch metrics over successive time slots.  The updated path metrics of states two time slots prior to the given time slot and the branch metric sums are added up in the adders.  The outputs of adders in pairs are compared respectively by first comparators to determine the highest of the adder outputs.          The determined highest values are passed through first selectors to a second comparator to further determine the highest of the selected adder outputs, the further determined value being passed through a second selector to the path metric source to update the previous value.          Control signals indicating the determinations taken by the first and second comparators are coupled to a path memory for storing data indicating the paths of the selected values.

Abstract: ABSTRACT A multiplier for multiplying the modulated sound and picture carriers to produce an intercarrier sound signal in a quasi-parallel sound channel of an IF section has a pair of anti-parallel connected diodes in a limiter for generating an amplitude limited version of the picture carrier.  It has been discovered that the varying capacitance of the diodes with picture amplitude can cause phase shifts and hence phase modulation interference in the intercarrier signal.  The latter is especially troublesome for stereo sound reproduction.  To reduce such interference, a low value resistor is shunt coupled to the diodes to inhibit the capacitance variations of the diodes and resulting undesired phase modulation in the intercarrier sound signal.

Abstract: ELECTROSTATIC ISOLATION APPARATUS AND METHOD          Abstract of the Disclosure An isolator for electrically isolating an electro-statically charged, electrically conductive coating material supply line from a grounded source of conductive coating material while continuously transferring coating material from the source to the supply line.  The isolator includes a recep-tacle for a charged coating material reservoir and an insula-tive housing surrounding the charged coating material recep-tacle.  The coating material in the receptacle is fed through an outlet to the supply line for an electrostatic coating device, which is electrostatically charged.  Due to the conduc-tive nature of the coating material, the electrostatic poten-tial at the coating device is coupled through the coating material, and the reservoir of coating material in the recep-tacle is likewise electrostatically charged.  The coating material from the grounded coating material source is coupled to a grounded nozzle assembly in a housing which is positioned above the charged coating material receptacle.  The grounded coating material nozzle assembly includes a nozzle in a bottom portion thereof, and the coating material in the grounded nozzle assembly is mechanically vibrated to produce a pulsed jet droplet flow of electrostatic coating material from the nozzle into the charged coating material receptacle.  A grounded metallic shield is mounted in the housing between the two coating material receptacles to substantially electrically shield the grounded nozzle assembly from electrical potentials below the shield, including the electrical potential of the charged coating material reservoir.  The shield is apertured to permit the passage of the pulsed jet droplet flow of coating material.

Abstract: ABSTRACT OF THE DISCLOSURE    A low-cost, full-function container includes a tubular convolute, spiral-wound, continuously formed, or die-cut formed paperboard or composite material structure of various geometric shapes to enclose a thin-walled vessel of material constituting a barrier for enclosing and protecting a product, the structure having sufficient thickness and rigidity for supporting and protecting at least the enclosed sides as well as the bottom of the vessel.  The vessel material wall thickness is inadequate for permitting the vessel conventionally to serve alone as a container for the product and to withstand the stresses of processing, filling, merchandising, distribution, storage and handling.   A closure for the vessel at its upper end seals the product hermetically or atmospherically with the product being protected from the air, other gases, moisture and light.  The material for the vessel is of such thinness that it alone would be unable to withstand such stresses.  The material is selected from one of various resins and polymers having minimum required barrier characteristics against water vapor, oxygen and/or gas permeation, as dependent upon the product to be contained.  Metal or glass may be also used for the vessel.  The vessel may be formed in situ within the structure.  Various interrelationships between the vessel and structure enhance package integrity and strength.  One such arrangement provides for a tamper proof container.  The container achieves lowest possible cost of materials, maximizing the functional characteristics of the materials used and minimizing the amount or thickness used, thereby effectively producing a significantly lower cost rigid or semi-rigid package. A variety of materials including carbonated beverages and other perishable liquids and foods may be packaged in the container.

Abstract: ABSTRACT     IMPROVEMENTS IN REGENERATIVE HEATING SYSTEMS     A regenerative heating system comprises two heat regenerators 1 and 2 of the type which are operable so that while one is being heated by waste gas the other is heating air for the combustion of fuel.     The regenerators 1 and 2 communicate with each other adjacent one end to form a chamber 11 into which fuel gas is injected by means of a fuel pipe 3.  The waste gas enters its respective regenerator by way of end 8 and passes through the bed 5 of the regenerator which stores the heat.  Air travelling in the opposite direction is heated in the bed 5 and entrains the fuel gas.  The steps 12 provide a venturi or choke effect on the air causing the pressure in the regenerator heating air to be lower than that in the regenerator being heated by waste gas.  Fuel gas is thereby drawn into the air stream for admixture therewith and ignition for combustion by means of a pilot light 14.
