Abstract: Abstract of the Disclosure A negative resistance device is formed by a series-connection of a complementary pair of insulated gate type FETs (field effect transistors), the sources of the FETs being connected to each other and the gate of each FET being connected to the drain of the other FET.  At least one of the FETs has a double layered gate insulating film under the gate electrode, thereby forming a non-volatile memory element. The device acquires or loses a negative resistance character-istic by responding to signals on the gates, thereby memorizing the signals.  A highly efficient memory which requires little power during writing-in, erasing and memory-holding, can be achieved in this way.

Additionally, an improved construction provides an expansion joint so as to allow axial longitudinal move-ment of the inner high-voltage conducting elements relative to the outer grounded metallic sheath, or casing due to differences in temperature and coefficients of thermal expansion therebetween.           An additional feature of the invention is the improved connection of the supporting insulator structure with adjacent high-potential components.           Another important feature of the present invention is the truncated configuration of the supporting insulator assembly.

Abstract: Abstract A process for making an integral one piece rotor liner for use with a high speed rotor.  The liner has an inner chamber and an annular chamber designed to operate in conjunction with the rotor operation to automatically allow fluid communication between the respective chambers during centrifugation and automatically establish a seal between the respective chambers subsequent to the centrifugation operation.  The process for making the one piece rotor liner generally comprises a first step of molding the liner in an intermediate elongated configuration wherein the inner cham-ber portion is integrally joined to and spaced from the annular chamber portion of the liner by a reversing section.  The general configuration of the inner chamber is located at one end of the elongated liner shape and the general configuration of the annular chamber is located at the other end of the elongated liner.  While the annular chamber portion is held in a generally fixed and rigid position, an external force is placed on the inner chamber portion of the elongated flexible liner in a direction toward the annular chamber, causing the reversing section to roll back on itself and move the inner chamber into a fixed recessed position within the annular chamber to establish the convoluted liner configuration with a dividing wall between respective inner and annular chambers.

Abstract: CONTROL SYSTEM FOR REFUSE PELLETIZING PROCESS                       Abstract Disclosed herein is a control circuit employing instantaneous and delayed action bistable switching elements for use in controlling the flow of refuse in a multiple channel, extrusion type briquetting or pelletizing system wherein the refuse is supplied from a conveyor to a common chute feeding a pair of extrusion-type compactors.  A vane arrangement in the common chute is driven in a reciprocating cyclical manner to feed the refuse in an alternating manner to the compactors.  The control circuit disclosed herein senses the cyclical action of the reciprocating vane and con-trols in turn the conveyor system which supplies refuse to the chute.  Certain deviating actions of the vane system indicate conditions signalling an incipient jam in the system flow.  The control circuit, in sensing such actions and in concomitantly interrupting the feed of refuse, corrects the feed rate to alleviate the potential jam-producing conditions.  Provisions are also included for interrupting refuse feed by excessive compactor pressure sensed by the control circuit.
