Abstract: ABSTRACT OF THE DISCLOSURE:     Process for the manufacture of discontinuous fibrils by the abrupt pressure release through an orifice of a two-phase liquid mixture of molten polymer and solvent which is at elevated temperature and pressure so as to bring about the instantaneous vaporisation of the solvent and the solidification of the polymer, the solvent not dissolving more than 50 g/litre of polymer under normal conditions of temperature and pressure and possessing a normal boiling point of more than 20°C lower than the polymer melting point.  The process is characterized by the fact that a make-up fluid is introduced into the two-phase liquid mixture before the pressure release is complete.  The fibrils obtained are parti-cularly suitable for the production by the usual methods of non-woven textiles and synthetic papers.

Abstract: ABSTRACT OF THE DISCLOSURE           A time-base error correction system for a video signal employing a plurality of serially connected delay lines.  Circuit means are conditio ed to detect the closest timing match between a reference synchronizing signal and the video signal as it appears at various points along the delay path and to connect the appropriate delay line point or junction to an output at which the correctly delayed video signal appears.  Featured circuitry provides for eliminating the erroneous leading edge of a video synch-ronizing pulse distorted by changes in the selected delay point and for compensating for variations in d.c. offset of the video signal introduced by differential delay line path effects.

Abstract: ABSTRACT OF THE DISCLOSURE      A metal cover has a hole into which an insulating resi-lient T.F.E. bushing is force fitted.  A metal terminal is pushed into the hole in the bushing.  These three parts are essentially coaxial and form a cover-terminal assembly that is subsequently placed between and compressed by a pair of coining dies to deform the cover metal adjacent to the periphery of the cover hole.  This coining step forces metal tightly against and into the resilient bushing subsequently compressing the bushing about the terminal. This terminal-cover assembly is particularly suitable for closing the housing of a hermetically sealed electrolytis capacitor.

Granted: 1978-10-17
Abstract: ABSTRACT OF THE DISCLOSURE           The specification describes an inserter for delivering soft, deformable tampons into body cavities and the combination of the inserter with a suitable tampon.  The inserter is made up of a pair of telescoping elements.  The outer element is in the form of a tube.  The inner element may also be in the form of a tube and has a main portion slidably disposed within the outer tube and a front portion comprising a smaller diameter frontal extension axially disposed on the forward end of the main portion and having a length substantially as long as the outer element when the inner element is slidably disposed therein.  In the inserter and tampon combination, the tampon is made from single or multiple sheets of resiliently deform-able material in various shapes.  The resilient tampon is disposed within the outer tube to provide a forward head portion and a trailing drape-like portion with at least the trailing portion being deformed and held in releasable compres-sion between the frontal extension and the outer tube.  In this arrangement, the leading end of the frontal extension bears against the inside of the head portion of the tampon and when the inner element is advanced inside the outer tube to deposit the tampon in the vagina, the head portion of the tampon is urged from the outer tube while the trailing portion is drawn from the outer tube.  Upon ejection the resiliently deformable nature of material from which the tampon is made permits the tampon to expand as far as the restrictive walls of the cavity permit and thus generally conform to the irregular shape of the cavity.

Abstract: Abstract Of the Disclosure An undervoltage trip coil and armature, with a pivotal member biased against and riding on the latch pin of the armature to sense its position.  On occurence of a low voltage condition, a trip lever causes the latch mechanism of the breaker to trip.  The pivotal member then interferes with the latch and prevents reset.  The undervoltage trip coil is normally energized to normally attract the undervoltage armature.  On occurrence of a specified undervoltage condition the armature releases causing the trip lever to trip the latch mechanism and allowing the pivotal member to interfere with the latch of the breaker.  During such condition, the breaker cannot be reset until the armature is attracted to the under-voltage coil under proper voltage condition.

Abstract: ABSTRACT Novel single film bipolar membranes, of substantially improved efficiency and durability, i.e. having an ion selectivity above 80% in an electrolyte medium of about one mole, are prepared from pre-swollen films containing a relatively high amount, i.e. at least 15% of an insoluble cross-linked aromatic polymer. Under controlled conditions, highly dissociable cationic-exchange groups are chemically bonded to the aromatic nuclei to a desired depth of the film from one side only; subsequently, highly dissociable anion-exchange groups are chemically bonded to the unreacted aromatic nuclei on the other side of the film. The functionalized, densely structured single film ion exchanged membrane undergoes negligible degradation, is blister free, and is uniquely suited for electrodialysis particularly water-splitting operations due to its low electrical resistance and low salt leakage. The mem-brane operates with improved current efficiencies at both high electrolyte concentrations and high current densities, for the periods not previously achievable.
