Abstract: ABSTRACT OF THE DISCLOSURE         Wall structure for a smelting stack is comprised of a cooling fluid flow pipe membrane layer comprised of a series of vertical, parallel arranged pipes extending between upper and lower manifold members.  The pipe membrane completely sur-rounds a hot zone in the smelting stack.  The upper and lower manifolds extend interiorly of the pipe wall membrane to define an alcove in which there is positioned a series of vertically arranged lengths of insulation cladding which are spaced from one another by gaps filled with fire-proof materials.  The gaps contain elements of the pipe membrane layer directed in-teriorly of the pipe membrane.  A waste-gas stack may be mounted directly adjacent the smelting stack with a common wall there-between.  The waste-gas stack wall comprises only a pipe mem-brane.  The primary function of the stack wall structure in the waste-gas stack is to remove heat from the waste gases; whereas, the primary function in the smelting stack is to retain heat within the stack and enable the furnace wall structure to withstand the smelting heat.  A common wall serves both these functions.  Since the load-bearing elements of the wall struc-ture are the pipe membranes, the stack wall structures may be supported in a blast furnace system by suspension from the upper manifold or erection upon the lower manifold.

Abstract: CENTRAL OFFICE INTERFACE CIRCUIT          Abstract of the Disclosure An interface circuit for interconnection between a central office line and a telephone apparatus (e.g. telephone set, automatic telephone answering machine, etc.) is disclosed.  The interface circuit includes a rectifier which allows the interface circuit to be connected across the central office line, in parallel with other interface circuits, without the use of isolation switches.  The rectifier rectifies any AC signal that may be present (e.g. voice signals) and applies the rectified signal to a normally present capacitor.  These AC signals, now rectified, cause the capacitor to become charged; once charged, the current path via the capacitor is effectively blocked.  As a consequence, AC signals are not passed by the capacitor.                             - i -

Abstract: ABSTRACT           NOVEL ANALOG FIBER FORMATION      The  object  of  the  present  invention  is  to provide a meat analog having a highly distinct fibrous structure.     The successful simulation of natural meats from texturized  proteinaceous  materials  depends  to  a great extent on its appearance, mouthfeel and chew. Prior art meat analogs prepared by simultaneously elongating and heating a dough containing a heat-coagulable protein have shown good fibrosity.  The present invention improves the fibrous structure of products of this type by employing in the dough a modified cellulose which is soluble at a temperature below the heat-coagulation temperature of the pro-tein  in  the dough but  is  insoluble  at  the heat coagulation  temperature.   The  resulting  product exhibits a more distinctly fibrous structure.     According to a preferred embodiment, the dough contains hydroxypropyl cellulose and is elongated by means of a heated auger-fed extruder.

An indexable insert having front and rear planar surfaces is receivable in the insert pocket, along with at least one locking wedge, which is interposed between the insert and the pocket walls for securing the insert within the pocket.  In accordance with the subject invention, an adjustable locating wedge is provided for regulating the axial location of the insert.  The locating wedge, a portion of which is disposed in abutting relationship with the axially lowermost cutting edge of the insert, is received within a groove located in the rear wall of the insert pocket.  The receiving groove is aligned with the insert and extends radially inwardly from the periphery of the cutter body.  In addition, the receiving groove is disposed at an angle relative to the rear wall of the insert pocket such that as the position of the adjustable locking sedge is varied within the groove, its axial position relative to the cutter body is also varied.  By this arrangement, the axial position of the insert, which resets on the locating wedge, can be adjusted.  More specifically, as position of the locating wedge is varied within the groove, its axial position is varied, thereby varying the axial position of the insert.  In a preferred embodiment, an adjustable insert seat is provided to vary the radial position of the insert.

Abstract: Abstract A current limiting field effect resistor device consists of a substrate and a layer of monocrystalline semi-conductive material overlying the substrate.  This layer comprises adjacent n+n-n+ regions, whereby the device operates with a linear current characteristic relative to small voltage signals and with a non-linear current characteristic relative to large overvoltage signals.  A voltage gradient occurs in the n- region in response to a large overvoltage signal applied to the device to thereby cause current pinchoff and constant current operation.  A dielectric layer covers at least the n- region of the layer of semiconductor material, and a pair of spaced apart electrically conductive gate regions are disposed over the dielectric layer to control the resistance of the device when a large overvoltage signal is applied to it.  As a result, the device is relatively insensitive to overvoltage signals.

Abstract: HEAT EXCHANGE SYSTEM     Abstract A plurality of parallel heat exchange tubes are grouped together and connected at the ends to form a bank.          One or more banks are positioned so that one end lies in a supply air stream and the other end lies in an exhaust air stream.  Each bank of tubes is sealed and contains a working fluid of the type having a liquid phase and a vapor phase. At one end of each tube, the working fluid absorbs heat from one of said air streams to effect vaporization of said fluid, the vaporized fluid flows to the cooler end of said tube where said vaporized fluid gives up heat to the cooler air stream and condenses in the tube.  The condensed fluid then flows back to the warmer end by means of gravity.  One end of the lowest tube in each bank includes a reservoir connected thereto which communicates with the normally cooler air path and in-cludes a heating coil operatively associated therewith for providing a modulated control of the system responsive to the temperature of the enclosed space being ventilated.  Additionally, a second control system turns selected banks of heat tubes on and off to prevent frost from forming thereon.
