Abstract: R.ND 140 "ELECTRICAL GENERATING SYSTEM, PARTICULARLY FOR AUTOMOTIVE USE"                ABSTRACT     To prevent unusually high or low voltage output from an automotive-type alternator, in case of failure of connection from the alternator rectifier output to the automotive vehicle battery, a connecting network is provided connecting an auxiliary alternator output terminal to the voltage sensing circuit to control the voltage sensing circuit to in turn control the field current to the alternator to prevent excessive output voltages.  Addition-ally, a further voltage sensing circuit is connected to the auxiliary terminal to provide limited energization to the field for self-excitation of the generator if the vehicle engine, driving the generator  is started, for subsequent transfer of control to the main voltage sensing circuit, but to prevent continuous field current flow at full field current value to prevent burnout of the field in case the engine is not started, but the main vehicle switch, typically the ignition switch, is left closed.

Abstract: BETA-AMINO CARBONYL CATALYSTS FOR      POLYURETHANE PREPARATION              ABSTRACT OF THE DISCLOSURE         Provided as catalysts for the formation of cellular urethane polymers ranging from flexible to rigid foams, are beta-amino carbonyl compounds wherein carbonyl is present as an amido or carboxylic acid ester group ant the beta-amino group is present as dialkylamino or an N- morpholino or N,N'-piperazino heterocyclic nucleus.  Effective in the catalysis of the water isocyanate reaction, these beta-amino amides and beta-amino esters are used with particular advantage in the manufacture of water-blown flexible foams, both molded and free-rise, including high-resilience and flame-retarded foam. The beta-amino carbonyl catalysts allow for the formation of foam products essentially free of the odor associated with amines such as N-ethylmorpholine.  In view of this highly desirable characteristic and their other beneficial properties, the catalysts of the invention are advantageously employed as direct replacements for N-ethylmorpholine in high-resilience and other foam formulations.

Abstract: ABSTRACT The invention relates to apparatus for use in the production of mouldings of a plastics material which initially consists of at least two liquid components which have to be intimately mixed before introduction into a mould.  In a known form such apparatus comprises a mixing head, and for each component to be mixed, a reservoir tank, a pump for supplying the component from the reservoir tank to the mixing head, and a valve at the mixing head operable to direct the component either into the mixing head or back to the tank.  In such apparatus and according to this invention the valves are arranged within the housing of the mixing head, the reservoir tanks, the pumps and the mixing head are mounted on a metal block in good thermal contact therewith, and the metal block and the housing of the mixing head are formed with ducts through which the liquid components flow.    The metal block and/or the reservoir tanks, and if necessary the pumps, may be provided with thermostatically controlled electric heating elements to ensure that these parts are each maintained at the required operating tem-perature and by running the pumps for a time before a mixing operation uniformity of temperature of each liquid component throughout the system is ensured.

Abstract: GUIDE RAIL ASSEMBLY FOR THE EJECTOR OF A SCRAPER AND METHOD     A B S T R A C T   A scraper comprises a bowl structure having an ejector assembly reciprocally mounted thereon for selectively discharging material forwardly of the bowl structure.  In one embodiment, a guide rail assembly is secured interiorly on each sidewall of the bowl structure to engage a guide roller, rotatably mounted on the ejector, for guiding the same during its movements in the bowl.  Each guide rail assembly comprises a cylindrical guide rod secured on a respective sidewall by a pair of locating rods disposed on either side of the guide rod and welded between the guide rod and the sidewall. The guide rod is secured to the sidewall of the bowl structure by placing a first linear  portion thereof adjacent to the sidewall and then placing first linear portions of the locating rods on either side of the guide rod to space it from the sidewall at a first predetermined distance.  This procedure is followed along the entire lenghts of the guide and locating rods to compensate for any irregularities that may be formed in the sidewall whereafter the located rods are welded between the guide rod and the sidewall. In a second embodiment, the guide rail assemblies are secured to a push frame of the bowl structure to engage guide rollers rotatably mounted on a rear-ward extension of the ejector assembly.

Abstract: MINOR BIT REDUCTION ON A MAGNETIC HEAD  Abstract A magnetic head assembly for cooperating with a relatively moving medium, on which servo information and data information is recorded, and for reading and/or writing on said medium and for erasing said medium is fabricated so that the effect of pickup interference or unwanted signals during playback is reduced.  The magnetic head assembly incorporates a geometry which shifts the signal envelope of the interfering signal so that it is in phase with the signal envelope of the desired signal.  The preferred geometry is to dimension the head core so that the distance between two gaps or between a single gap and the edge of the core is equal to the distance between the servo tracks on said media. Additionally, the gap of the head has a gap null occurring at the frequency of the interfering signal.

Abstract: PHOTOTRANSISTOR            Abstract of the Disclosure A phototransistor is operated with a floating base but with the transistor operating point defined by prebiasing the base, typically by injecting the base current through a prebias emitter in the collector region outside of the depletion layer.  The phototransistor has a signal to noise ratio comparable to those of optimized avalanche photodiodes but operates at a significantly lower voltage and without need for temperature compensation.          The phototransistor is especially well-suited for optical communications at high data rates.

Abstract: ??     ABSTRACT     The disclosure illustrates an insulated composite piston comprising a crown of ceramic or other heat resistant material secured to an  aluminum piston body by a bolt of temperature resistant alloy.  A low conductivity interface between the crown and the body is provided by a series of stacked discs having low effective thermal conductivity.          The relative thermal expansion of the parts is compensated for by bellville washers on the bolt.  The above arrangement insulates the crown from the piston body thereby minimizing the temperature gradient across the crown so that its temperature can be maintained as high as necessary to increase efficiency and minimize noxious emissions.

Abstract: ABSTRACT OF THE DISCLOSURE An improved process for obtaining highly purified phosphatidylcholines (lecithin) including a high content of essential fatty acids is disclosed.  Raw lecithins are first extracted with a lower alcohol of 1 to 3 carbon atoms. The resulting two phases are separated and the alcohol-rich upper phase is treated with an aluminum oxide ad-sorbent.  Elution of the adsorbent with an alcohol (as in known processes) results in an oily phosphatidylcholine, free of cephalin and inositol phosphatides but possessing a high content of essential fatty acids.

Abstract: ABSTRACT     Two separate but identically shaped sections cooper-ate to form an electrical cord gripping device when they are brought together.  The sections are insertable into recesses in cooperating halves of an electrical housing, by wedging or snapping them into place, and, when the housing is closed, the sections form a restricted opening and provide a clamp around an electrical cord passing through the opening and into the housing.          The sections are readily removable from the housing, so that a single housing can be used with electrical cords of different sizes.  Further, each section contains a diagonal rib, and, when the sections are brought together, their ribs criss-cross one another to grip the cord from opposite sides.  The sections are also shaped to provide abutting surfaces which overlap each other to cam the sheathing of the electrical cord into the open-ing provided by the sections, and prevent crimping of the sheathing.
