Abstract: PRIMARY ELECTRODE ARRANGEMENT FOR HIGH TEMPERATURE MELTING FURNACE              ABSTRACT Prior art high temperature electric furnaces of the type using two or more, usually three, primary electrodes positioned around an electrically conducting central outlet brought the electrodes in through a side or bottom wall of the furnace at points below the melt line causing many problems.  The present invention provides a primary electrode arrangement for such melting furnaces wherein the primary electrodes do not pass through the wall or bottom of the furnace below the melt line, but instead enter the furnace over the top of the melt line and then protrude through the top surface of the melt.  The primary electrodes of the present invention are provided with means for preventing wear and deterioration at the interface between the top surface of the melt and the unmelted batch and/or the oxidizing air atmosphere surrounding the top of the furnace.  The improved furnace of the present invention does not require the use of a purging neutral or reducing atmosphere to protect the primary electrodes.

Abstract: ABSTRACT OF THE DISCLOSURE       A generally cylindrical casing is hollow, and is supported by a base so that the axis of the casing is horizontal.  A vertical partition divides the casing into a fire chamber and a smaller exhaust chamber.  The smaller chamber is vented to the outside atmosphere by a chimney.  The partition does not completely isolate the chambers, but enables them to be interconnected through a small gap at its bottom.  Extending rearwardly along the curved portion of the casing are two oppositely disposed parallel horizontal elongated air intake slits at the level of the bottom of the partition.  The major portion of the section of the casing that surrounds the fire chamber is of glass.  The base can have a horizontal shallow half cylindrical shell at its top which supports the casing and a vertical hollow intake duct extending from a bottom opening in the base to the slits to feed air thereto.  Alternatively, one of the slits can be defined by the gap between a hinged lid and the casing providing access to the chamber.

Abstract: ABSTRACT OF THE DISCLOSURE          A coulometric titrator for determining, at high accuracy and without time delay problems, small amounts of a specific (chloride) ion in a solution by the addition of a reactive ion. A sensor provides a first voltage representing the logarithm of the specific ion concentration to a differential amplifier which also receives as an input a signal from a reference electrode. The differential amplifier produces an error signal applied to a comparator and referenced therein to a certain reference voltage representing a desirable range of rates of change of the error output voltage.  The comparator provides a sensor signal voltage representing the difference between the error signal and reference voltage.  This sensor signal voltage is applied to an antilogarithm, converter which produces an output signal that is proportional to the antilogarithm of the sensor signal voltage.  The output signal is received by a reactive ion (silver metal) source means associated with a current source passing a unidirectional current flow between an inert cathode immersed in the solution and the reactive ion source means as an anode for the introduction of the reactive ion (silver) into the solution. As a result, the second signal voltage changes at a constant rate with time, and the reactive ion addition changes in a logarithmically decreasing amount with time in the sample solution until the stoichiometric end point is approached.

Abstract: METHOD OF MAKING MOS DEVICE          ABSTRACT          The invention relates to a method of making MOS semiconductor devices.  A single crystal silicon substrate has the following layers formed thereon according to a pre-determined pattern: firstly there is an oxide film next to the silicon substrate, secondly a high-temperature-resistive film (such as a metal or polycrystalline silicon) overlies the oxide film and thirdly an oxidation preventing film overlies the high-temperature-resistive film.  The high-temperature-resistive film is eventually to become a gate electrode and should resist melting during the step of diffusing an impurity into the substrate at exposed parts thereof to form source and drain regions.  After the diffusion step the device is subjected to thermal oxidation so that the exposed side-end parts of the    high-temperature-resistive film and the exposed parts of the substrate are oxidized.  Further steps are then carried out in the preparation of the device. By this method the usual overhang of the edges of the high-temperature-resistive layer is avoided thereby improving the drain-breakdown voltage, lowering the gate leakage current and reducing the possibility of open circuit conditions in vapor-deposited metal wiring films.

Abstract: RESETTABLE, HEAT ACTUATABLE FIRE LINK                   Abstract of the Disclosure A resettable fire link is described comprising a releasable member, gripping means for engaging said releasable member in the normal position and for releasing said releasable member in the activated position.  Said gripping means comprises heat responsive means for causing said gripping means to move to the normal position in response to an ambient temperature and for causing said gripping means to move to the activated position in response to a preselected increase in said ambient temperature.  Mechanical activation means are also provided for movement from a first withdrawn to a second extended position.          In said first withdrawn position, the mechanical activation means allows said gripping means to move freely between its normal and said activated position, as aforesaid.  The mechanical activation means also may independently cause said gripping means to move to the activated position.  As a result, a novel heat and/or remote mechanically activated fire link is provided which is ideally suited for disposition in a "dirty" environment such as might be found in a poorly filtered ventilating system.         The fire link of the present invention maintains excellent heat response characteristics, is resettable, and will function under fail-safe conditions, that is, either in response to a preselected increase in ambient temperature, or in response to the remote activation of the mechanical activation means.  If a malfunction occurs in one of the alternate activation means, the other activation means is free to function.
