Abstract: IMPROVED PROCESS FOR THE EXPEDITIONS FORMATION AND STRUCTURAL MODIFICATION     OF POLYMERIC FIBERS AND FILMS                      Abstract of the Disclosure An improved process is provided for the production of polymeric filamentary material or film. Molten melt-spinnable polymeric material capable of undergoing crystallization (e.g., a polyester) is extruded through a shaped orifice to form a filamentary material or film under high stress conditions, quenched to below its glass transition temperature to form a solid filamentary material or film, and sequentially passed for a brief residence time through a thermal conditioning zone at a temperature between its glass transition temperature and its melting temperature wherein the internal structure thereof is modified and substantial crystallization of the previously solidified filamentary material or film takes place. The filamentary material or film is withdrawn from the conditioning zone at a rate of 1000 to 6000 meters per minute while under a relatively high stress of about 0.1 to 1. 0 gram per denier.          The process is conducted while exerting a constant tension upon the filamentary material or film in the absence of stress isolation. The melt extrusion process yields a product wherein the tensile strength and modulus are improved and the shrinkage characteristics are diminished.

Abstract: METHOD AND APPARATUS FOR THE CONTROLLED GENERATION    OF WALL-ENCODED MAGNETIC BUBBLE DOMAINS          Abstract of the Disclosure A magnetic layer is exchange coupled to a bubble medium in an area where bubble domains are nucleated, and is used together with or with-out an externally applied in-plane magnetic field to controllably generate bubble domains with either one pair (S = 0) or no Bloch lines (S = 1), respectively.  The exchange coupled magnetic layer can be either an ion-implanted layer, a thin garnet film with planar magnetica-tion, or a thin permalloy film.  The exchange coupled magnetic layer may be positioned either on top of or below the bubble film used for storage. An information store utilizing domain interaction for bubble domain Storage such as lattice array is accomplished by having each bubble domain representing either binary bit according to its domain wall state.  The controlled switching of bubble domain wall states from any state to either one of two known states can be achieved by sub-jecting the wall of the bubble domain to a critical velocity, depend-ing upon the application or not of the external in-plane magnetic field to the exchange coupled magnetic layer.

Abstract: Abstract of the Disclosure Method and apparatus are described that are operative to elevate the temperature of superheated vapor delivered to a turbine, especially during startup of a power plant.  A bypass circuit containing a heat exchanger is interposed in the main steam generator evaporative flow circuit whereby regulated amounts of heat are extracted from the plant operating fluid thereby subcooling the same prior to its passage to the evaporator section of the unit.  Reduced amounts of steam are thus produced in the evaporator section for a given amount of heat input to the unit and a concomitant increase realized in the temperature to which the steam passed to the superheater is heated. Economies as well as operational advantages are achieved by the production in the heat exchanger of low pressure steam that is usable in the plant to augment steam flow to the low pressure section of the turbine, for soot blowing purposes, and/or for other low pressure steam needs during startup and normal operation of the plant.

Abstract: ABSTRACT OF THE DISCLOSURE           A coupling capacitor voltage transformer or potential transformer has its secondary winding tapped to provide a predetermined voltage across a portion of the secondary winding.  The transformer is improved by an inductive reactance added in series with the secondary tap.  The magnitude of the added inductive reactance is selected so that the sum of the added reactance and the leakage reactance between the transformer primary winding and the portion  of the secondary winding referred to the primary is equal to the leakage reactance between the primary winding and the full secondary winding referred to the primary.  Under this equality condition, the phase relation between the primary and secondary voltages will be the same for a standard type burden or equivalent burdens connected either across the portion of the secondary winding or across the full secondary winding.  The added inductive may also be used with a separate secondary winding having a lower referred leakage reactance to provide a phase relation for that secondary winding that is the same as the phase relation for the secondary winding having a higher referred leakage reactance.

Abstract: SYNCHRONOUS, NON RETURN TO ZERO                BIT STREAM DETECTOR                      Abstract Signals over a data channel are detected for the pre-sence of a non return to zero, psuedo random coded bit stream which is synchronized to a clock frequency and con-tains submultiple harmonics thereof.  The submultiple fre-quencies occur at discrete integer intervals ranging from 1/2 to 1/N of the clock frequency, where N is an integer dependent upon the data generation scheme.    The detection system employs an improved quadrature detector which compares narrow width window pulses, derived from the clock signal, which occur in quadrature to the encoded bit stream, with narrow width transition pulses generated at data signal transition time.  In response to the synchronous occurrence of a given number of window-transition pulses per time interval, the quadrature detector produces an inhibit signal, thus indicating the absence of a detected data stream.    One system refinement is a minimum bit width detector which produces an inhibit signal if a 1/2 clock frequency submultiple is not detected within a given time interval.    A further refinement is a maximum bit width detector which produces an inhibit signal upon detecting a number of bits whose width exceeds N/2.

Abstract: Abstract of the Disclosure A cathodic protection system for a buried, fluid pipeline that has an electricallead or coil electrically coupled between the pipeline and a sacrificial anode. As the anode deteriorates by electrochemical reaction with its environment, a current flows through the lead or coil, producing an electromagnetic field that permeates the pipeline. The strength of this magnetic field can be correlated to the condition of the sacrificial anode and/or the condition of a protective coating on the pipeline. An apparatus for detecting the strength of the electromagnetic field travels through the pipeline in a scraper or similar device, senses the magnitude of the field, and generates a signal indicative of the condition of the cathodic protection system.
