Abstract: ABSTRACT OF THE DISCLOSURE There is provided a continuous  steady state process for the preparation of nonrandom ethylene/.alpha. .beta.-ethylenically unsaturated carboxylic acid copolymers in at least 2 constant environment, stirred autoclaves in series wherein the first autoclave is maintained at the pressure in the range of 800 to 3000 atmospheres (11.8 to 44.1 kpsi) and at a temperature in the range of 120° to 200°C in a single phase reaction mixture at the given concentration of copolymer in the reaction mixture and at the given acid comonomer content of the copolymer and wherein each suceeeding autoclave is maintained at a temperature of at least 30°C in excess of the preceding autoclave.  The copolymers thus obtained have a ratio of percent adjacent acid to weight percent acid in the copolymer of from above 0.44 to about 1Ø These copolymers have improved stiffness and are par-ticularly useful in sheeting, blow molding, and packaging applications and for conversion to ionomers which are also useful for similar applications.

Abstract: Abstract of the Disclosure A preferred bundle geometry providing a tight winding of filaments interlaced in such a manner that there is an even distribution of interfilament voids in connected tortuous paths and evenly distributed throughout the bundle, so that the fluid flow outside the filaments will have equal access to the surfaces of all the filaments is accomplished by helically winding the filaments with a rapid traverse, so that they enter from one end of the bundle to the other while passing around the circumference of the bundle.  Successive passes of winding turns will cross each other, with only a point contact at the cross-over, and with a network of fluid passages between the filaments.  This winding technique can be employed to wind the filaments around a central core or winding mandrel, and if this core is hollow, it can also be designed as a fluid exit or entry port into the interior of the bundle of filaments.

Abstract: ABSTRACT OF THE DISCLOSURE A direct current power supply is provided that supplies a relatively high current at low voltage to a load requiring a constant value of real power over a predetermined range of output voltages. The supply includes a three phase diode rectifier bridge connected across the load in parallel with a three phase thyristor rectifier bridge also connected across the load. The thyristor bridge has its alternating current inputs connected to secondary winding output terminals of a three phase transformer. The diode bridge has its alternating current inputs connected to intermediate tapped portions of the three phases so as to provide a predetermined minimum value of voltage for the range of voltage. The remaining voltages in the range are attainable by phase control of the thyristor bridge. The novel power supply results in an improved power factor and reduced reactive power requirements for the supply.

Abstract: LOOM STOP MOTION SYSTEM AND METHOD                    ABSTRACT     A precise, accurate and sensitive control method and system for actuating the stop motion mechanism of a weaving loom equipped with a weft yarn storage feeder unit is disclosed. The storage and feeder unit includes a device for applying tension to the weft yarn being delivered from a weft yarn supply to the storage and feeder device. The tension device is equipped with a switch which provides a first electrical signal when the weft yarn being supplied to the storage and feeder device becomes slack or interrupted. That switch is connected with the weft yarn storage and feeder unit motor circuit. The weft yarn storage and feeder unit may be intermittently driven as the need occurs for feeding a weft yarn length or pick into the loom. The loom is stopped only in the presence of two concurrent signals, namely (1) a signal generated upon the detection of slack weft yarn or the absence of yarn in the tension device and (2) a simultaneous signal indicating operation of the motor to drive the weft yarn storage and feeder device. By the operation of the loom stop motion mechanism only the presence of the aforementioned simultaneous signals, short picks, i. e., insertion of weft yarn lengths less than that required  to extend from one side of the fabric being woven to the other, is precluded.          Further, false signals which might arise from simple slackening of the yarn in the zone of the tension device are not operative to halt the loom.

Abstract: ABSTRACT OF THE DISCLOSURE         Hydrofluoric acid compositions and methods for dissolving siliceous materials in subterranean formations to stimulate the production of fluids therefrom are provided.          The compositions have a pH value of no more than 2 and are comprised of at least one mineral acid, at least one fluoride compound which is a source of hydrofluoric acid in the mineral acid, and an aluminum compound which is soluble in the mineral acid, and which upon dissolution in the mineral acid produces aluminum III ions.  The fluoride compound is present in the compositions in an amount sufficient to produce a fluoride ion concentration of at least 0.05 gram-moles of fluoride per liter of solution.  The aluminum compound is present in the compositions to produce a molar ratio of fluoride ions to aluminum III ions of from about 1 to 1 to about 6 to 1.          The presence of aluminum in the compositions retards the reaction rates thereof to thereby enable deeper penetration of formations by the acid compositions.

Abstract: VAPOR STRIPPING PROCESS     ABSTRACT OF THE DISCLOSURE     Protective and residual organic coatings are stripped from a surface by substantially sealing the surface from the atmosphere to provide a stripping zone, forming a stream of gaseous stripping composition in an evaporation zone, contacting the surface with the stripping composition in the gaseous state at about ambient temperature and recirculating the gaseous mixture from the stripping zone to the evaporating zone and back to the stripping zone to rapidly increase the concentration of gaseous stripping composition in the stripping zone. Optionally the surface may be rinsed by raising the temperature of the gaseous stripping composition slightly above ambient temperature, whereby the gaseous stripping composition condenses on the surface and flushes the surface free of adhering particles.  This process is useful for objects which can be placed in a stripping zone and substantially sealed from the atmosphere, especially objects having an irregular surface, and also for interior surfaces which can be substantially sealed from the atmosphere, including extensive surfaces such as those of storage tanks, tank cars and the holds and ballast tanks of ships .

Abstract: Abstract A low alloy steel composition having a medium carbon content which is capable of use as a forging die in closed die forging and in which surface problems, such as panel cracking, in the manufacturing process have been eliminated, or the frequency thereof very greatly reduced as contrasted with conventional steels.  The invention provides such a steel in which the reduction of area transverse is in the range of from about 15% to about 30%, and in  which the ratio of reduction of area transverse to the reduction of area longitudinal closely approaches 1Ø         The steel has from about .50 to about .60 percent by weight of carbon and significant nickel, chromium, molybdenum, vanadium and aluminum constituents, and a small but effective quantity of titanium.  The method of producing such steel includes the feature of adding titanium to the molten steel at a point in the processing cycle in which oxygen content of the molten steel is at a low point whereby relatively harmless titanium carbo nitride is produced instead of aluminum nitride which is recognized as being deleterious to the attainment of the above-described properties.

Abstract: ABSTRACT OF THE DISCLOSURE           A suspension system supports a plurality of high voltage electrical conductors forming part of a transmission line in a predetermined spaced pattern relative to one another. The system includes a rigid compression strut arranged to extend generally horizontally between a pair of spaced primary support points.  A flexible tension member is suspended below the compression strut and has its opposing ends connected at said primary support points.  When the tension member is loaded it applies compression forces lengthwise of the strut.  An array of insulators is disposed below the flexible tension member for supporting the plurality of electrical conductors in the preselected pattern relative to one another.  At least certain of these insulators are connected to the tension member so that the latter bears a portion of the total loading imposed by the conductors.
