Abstract: ABSTRACT OF THE DISCLOSURE A furnace vessel comprises a vertically oriented refractory lined cylindrical metal shell and a cover. The interior bottom of the vessel is dish shaped the vessel has external upwardly ending molten metal receiving and pouring spouts leading to the upper surface of the bottom. The inlet to the receiving spout is higher than the outlet of the pouring spout whether the vessel is untilted or tilted to enable addition of molten metal to the vessel at all times. Means are provided for tilting the vessel on an axis that is on the same side of a transverse mid-plane through the vessel as are the pouring and receiving spouts. The tilt axis is directed through the outlet end of the pouring spout so the level of its tip is substantially unchanged when the vessel is tilted. The temperature of the metal in the vessel is maintained by heat radiated from an electrically resistive rod which extends across the interior of the vessel above the metal level. The ends of the heating rod are provided with electrical connectors and supports which are mounted on carriages. The carriages are mounted on track sections which tilt with the furnace and align with cooperating stationary track sections on which the carriages may be traversed for servicing the rod when the vessel is untilted. The axis of the rod is aimed such that an extrapolation thereof will not cross over the tilt axis within the width of the furnace so that the carriages and tracks are clear of the working area around the receiving and pouring spouts at all times. The vessel is adapted for holding, reducing, alloying, degassing, vacuum treatment and introducing additives to molten metal during the interval between melting and utilization of the metal.

Abstract: A CLUSTER STORE APPARATUS FOR POST PROCESSING ERROR   CORRECTION OF A CHARACTER RECOGNITION MACHINE            ABSTRACT OF THE DISCLOSURE:          A cluster storage apparatus is disclosed for out-putting groups of valid alpha words as potential candidates for the correct form of an alpha word misrecognized by a character recognition machine.  Groups of alpha words are arranged in the cluster storage apparatus such that adja-cent locations contain alpha words having similar character recognition misread propensities.  Alpha words which have been determined to be misrecognized, are input to the cluster storage apparatus.  Numerical values assigned to the characters of which the input word is composed, are used to calculate the address of that group of valid alpha words having similar character recognition misread propensities.          The cluster storage apparatus then outputs the accessed groups of alpha words for subsequent processing.  The organization of the cluster storage apparatus minimizes the difference in address between alpha words with similar character recognition misread propensities by assigning high numeric values to highly reliable characters, as determined by measuring the character transfer function of the character recognition machine.

Abstract: PRINTED PATTERN AND EMBOSSED PATTERN      REGISTRATION CONTROL SYSTEM                    Abstract of the Disclosure A system is disclosed for securing registration of a patterned embossing roll with a similarly patterned printed moving web.  The pur-pose of the embossing roll is to indent the surface of the printed web in register with the printing in certain designated areas.  In one embodiment, a series of randomly spaced register marks on the printed web selvage edge and identically spaced register marks on the embossing roll are viewed by appropriate scanners.  Electrical signatures repre-senting the two sets of register marks are generated by the sensors and red to a signal correlator for comparison.  The correlator determines the degree of statistical error between the two signatures and displays this error in the form of a time delay on a CRT (Cathode Ray Tube).  If manual registration control is desired, an operator can manually adjust the speed or phase of the embossing roll by observing the peaked wave display on the CRT to bring the roll into a statistical best fit of the embossing pattern with the printed pattern.  Automatic control of embossing roll speed and orientation to achieve registration is also possible if the correlator is interfaced with a digital computer and servo correc-tion motors on the embosser drive system.  The disclosed system is an improvement over conventional benchmark oriented registration sensing and control systems in that it is capable of continuous error determin-ations and asynchronous error corrections on demand rather than period-ically at the end of pattern length intervals.

Abstract: ABSTRACT           In the production of an IMPATT diode a slice of semiconductor material having an epitaxial layer on an n+ substrate material is selected.  A p+ layer is diffused into the epitaxial layer to form an abrupt p+-n junction.  The diffused surface of the substrate is metallized with thin layers of titanium, platinum and gold in succession.  A relatively thick layer of gold is deposited by electroplating on to the gold layer.  The n+ plus substrate material is thinned to a desired thickness for the device.  A photolithographic mask is produced on the n+ plus surface of the substrate.  A succession of thin layers of titanium, platinum and gold are depoisted through areas defined by the photolithographic mask.  A thick gold layer is electroplated on to the thin gold layer and the photolithographic mask is removed so as to expose the surface of the n+ plus substrate material around a series of gold pads.  The zones of semiconductor material are passivated by high energy proton bombardment in depth through slice to create zones of semi-insulating material to isolate the semiconductor material directly below the gold pads.  The processed semiconductor material is mounted on a heat sink and one or more of the gold pads are connected to a connection block.

Abstract: A METHOD FOR PREPARING A MULTILAYER CERAMIC         Abstract A method for manufacturing a multilayer ceramic which is particularly suitable for carrying semiconductor chips.  In order to join a semiconductor chip to a multi-layer ceramic substrate, it is necessary that the projected site for the semiconductor chip be substantially flat.  If there is a bulge, it becomes difficult to make a good joint thereto.  The method involves depositing a particulate mix-ture containing a metal and the metal's oxide in a ratio of between 1:1 to 9:1 in a pattern on at least a portion of the plurality of ceramic layers.  The patterns are then dried.  The plurality of substrates or layers of ceramic are then laminated under substantial pressure and fired at an elevated temperature.  The addition of the metal oxide to the metal powder allows the shrinkage of the metallization compound so that it may more nearly match that of the ceramic it is coated upon during the firing step.  This matching of the shrinkage during firing pre-vents cracking of the ceramic.
