Abstract: PRECIS DE LA DIVULGATION:           La présente invention se rapporte à de nouveaux fils, fibres et crins à base de polymère synthétique, ayant un aspect mat et un toucher analogue à celui des fibres d'origine naturel-le.  Ils sont formés de filaments possédant une structure coeur-peau telle que le coeur est constitué par du polymère compact orienté  et la peau, dont l'épaisseur est comprise entre 0,5 et 10 µ est constituée par le même polymère sous une forme fibreuse et vacuolée, coeur et peau étant liés sans discontinuité.  Procé-dé de fabrication de fils, fibres et crins par filage du polymè-re à l'état fondu, puis étirage, caractérisé par le fait que les filaments issus d'une filière, sont immergés, à l'état fondu, dans un milieu de refroidissement, dont la température est infé-rieure à 100°C et gonflant du polymère lorsque la température de celui-ci est supérieure à celle de son point de solidification, non gonflant lorsqu'elle est à la température du milieu de re-froidissement, le pouvoir gonflant diminuant progressivement avec la température du fil depuis la température de solidification du polymère jusqu'à la température d'équilibre du milieu de refroi-dissement.  La nouvelle structure des produits selon l'invention apporte des caractéristiques intéressantes touchant entre autre la voluminosité, la faible aptitude à l'électrisation et la fixa-tion rapide de l'humidité.

Abstract: ABSTRACT OF THE DISCLOSURE A PUT circuit compares a zener reference voltage with the voltage of an electronic flash storage capacitor, and starts and stops a battery powered d.c. to d.c. converter oscillator, which charges the capacitor, as necessary to maintain the capacitor voltage within desired limits.  A zener diode in the PUT cathode circuit provides the desired hysteresis.  A second PUT circuit compares a second zener reference voltage with the battery voltage, and stops the oscillator when the battery voltage drops to a pre-determined minimum value.

Abstract: BATTERY PLATE AND METHOD OF MAKING SAME                   Abstract of the Disclosure A storage battery plate is provided having a core of aluminum, for example, which has its oxide coating replaced by a thin film coating of a metal such as zinc.  The zinc in turn is coated with a thin layer of silver.  Lead is thereafter de-posited over the silver coating in the usual manner to form a battery plate.  Alternately the oxide coating is removed and a thin film of lead is deposited thereon.  Such a plate has a higher conductivity and is lighter in weight with superior per-formance characteristics than a conventional lead-antimony plate.

Abstract: ABSTRACT OF THE DISCLOSURE      A molded plastic pivot body is formed with an intergrally molded sleeve bearing for journaling a pivot shaft of a wind-shield wiper system for a motor vehicle.  The bearing includes concentric, radially spaced sleeves interconnected by webs dis-posed in the annular spaces between the sleeves.  The inner sleeve is slotted axially, the slots being circumferentially spaced from each other.  The annular spaces between adjacent webs form grease retainers and the slots serve as shaft lubri-cator as well as dirt collector grooves.  The thickness of the outer sleeve wall is of a value which permits the outer sleeve to yield.  The bearing is arranged on the pivot body support bracket unconfined so that the outer sleeve is free to flex. The segments formed by the slots in the inner sleeve are resilient and flexible.  Radial forces applied to effect flexing of the segments id transmitted through the web to the outer sleeve causing it to yield.  A shaft of larger dimension than the inner diameter of the inner sleeve may be accommodated.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus is disclosed for conditioning a charge of molten cast iron, which would normally solidify with a flake graphite structure, to produce partial or total spheroidal graphite cast iron.  In addition, the method and apparatus can be used to further condition a partially conditioned cast iron to yield a partial or fully spheroidal graphite cast iron.  A recess is provided in the metal flow system (within or without the mold system) leading to the casting cavity or cavities.  The recess has a shape and cross-section cavity or cavities.  The recess has a shape and cross-section (taken in directions normal to the direction of flow of the molten charge) such that the spheroidizing agent dissolves uniformly when the molten iron flows over it to achieve unprecedented homogeneity.  A relationship is disclosed between charge weight, charge flow rate, magnesium concentration in the spheroidizing alloy, and interface area so as to determine a desired degree of nodularity in the final casting and/or to design a solution rate compatible with a specific casting technique.  The residual magnesium can be reliably maintained at a level sufficient to consistently obtain full spheroidal graphite shape.  A preferred magnesium level is 0.20% to 0.040% by weight of the weight of the casting but higher or lower levels can be reliably obtained if required by base metal chemistry.  This is significant since the prior art has been unable to reliably obtain full nodularity with 0.020 to 0.025% by weight residual magnesium under commercial conditions.

Abstract: ABSTRACT OF THE DISCLOSURE           In a thermoforming machine for forming products from plastic sheets or the like, two shuttles or sheet-carrying frames shuttle interchangeably between a feeding station and a forming and loading station, with the shuttle which carries the sagging heated sheet passing under the oppositely moving shuttle.  At opposite ends of a transverse axis at the longitudinal center of each shuttle, pivotal connections are provided to vertically looped drive chains so that the shuttle can remain right-side up as it follows the looped path of its chains.  Rails are pro-vided which support the shuttles and maintain them horizontal as they move.  At the forming and loading station, snorkels engage the shuttle stopped there to provide suitable air pressure and discharge connections for operating sheet clamps by double-acting cylinders. The snorkels thrust the shuttle rearwardly against a ratchet, for accurate stop-positioning between snug side-cams.
