Abstract: HIGH CONCENTRATION ENCAPSULATION               OF WATER SOLUBLE MATERIALS                 ABSTRACT OF THE DISCLOSURE         This invention relates to a process for encapsulation, and particularly to the production of small or minute capsules constituted by a skin or thin wall of polymeric material e.g., polyurea, polyamide, polysulfonamide, polyester, polycarbonate, or poly-urethane, which involves first providing an organic liquid (continuous phase liquid) containing an oil soluble alkylated polyvinylpyrrolidone emulsifier A discontinuous (aqueous) phase liquid containing a water-soluble material, which is the material to be encapsulated, plus a first shell wall component; is dispersed in the continuous phase liquid to form a water-soluble emulsion.  The second shell wall compo-nent is added to the water-in-oil emulsion whereupon the first shell wall component reacts with the second shell wall component to form a solid polymeric shell wall about the material to be encapsulated.  The capsules formed may be directly used as in the form of an organic suspension, i.e., a suspension of microcapsules in the organic liquid.

Abstract: ABSTRACT:           The head-mounting plate of a cassette apparatus is positioned, in part, through the operation of a servo having a motor-driven servo wheel whose rotation is ini-tiated by pulsed operation of an impulse relay.  The servo wheel has teeth around its circumference except for two portions defining wheel rest positions.  In the rest posi-tion of the wheel, a starting torque is applied by pres-sure on a cam on the wheel, rotation being prevented by a latching arrangement.  The impulse relay is engaged by a relay-armature member which has an elastically deflectable arm and a rigid arm, the end of the elastically deflect-able arm having a rigid support for a soft iron element which can be attracted to the impulse relay, and a coupling element which couples the elastically deflectable arm to the rigid arm, so that movement of the rigid arm in one direct is prevented by the engagement with the relay. Deflection of the deflectable arm permits movement of the relay-armature member through an additional pivotal move-ment toward the latching relay.  In the latching position of the relay-armature member, a stop on the member abuts a latching projection on the servo wheel to keep the wheel in a latched position.  An impulse energization of the impulse relay releases the soft iron element, and a spring pivots the relay-armature member to an inoperative posi-tion in which the servo wheel is freed to rotate under the influence of the starting torque, so that the circum-ferential teeth mesh with a drive pinion connected to a drive motor which may be constantly rotating.  A reset protection on the relay-armature member is actuated by the latching projection for pivoting the member back to the latching position so that the latching projection can abut the stop when the servo wheel has again reached the rest position.

Abstract: NON-ORGANIC/POLYMER FIBER COMPOSITE, METHOD OF MAKING SAME AND USE INCLUDING DIMENSIONALLY STABLE SEPARATOR                 ABSTRACT OF THE DISCLOSURE      The present invention relates to a new and useful composite fiber and its use, especially its use as a dimensionally stable separator.  The composite fiber is comprised of non-organic particulates bound to an organic polymer in fiber form and prepared by vigorously grinding or shearing a mixture of non-organic particulates and organic precursor particles for the polymer at elevated temperature.  Many non-organic substances are serviceable and valve metal oxides are highly suitable.  The organic polymer fiber is advantageously derived from fluorine-containing polymer.  The composite fibers can serve as a filter, for instance as a filter-packing material for column chromatography, or can be suitable for separations, e.g., battery separations.  The fiber may be compressed, or compressed and sintered, and thereby be useful as bearings or gaskets.  When used as a separator, the separator is preferably a diaphragm for use in electrolytic cells for the production of chlorine and caustic, and the method of its preparation is preferably by direct coating onto a foraminous cathode of an electrolytic cell from a slurry or paste of composite fibers, followed by drying and heating.

Abstract: ABSTRACT             A fence having security wires fastened to posts via sensors and having an electronic evaluation circuit connected to the sensors, which releases an alarm signal when one of the sensors signals a contact of the security wire which is connected to it.  Each sensor has a housing fastened to a post, a holder connected to a security wire and a transformer placed between housing and holder, which produces a signal which is approximately proportional to the position of the holder.  An alarm signal is generated when one or only a few security wires move slowly, yet such slow movements are ignored when caused by environmental factors.  A highly reliable security fence is thus obtained.

Abstract: An answer supervision method which has the steps of (1) Initialize and test all RAM and programmable hardware, (2) Establish software threshold for each channel and store in a Status Control Block, (3) Begin state driven analysis of cadences, (4) Analyze cadences without reporting results (Reset C), (5) Upon Reset A, try to detect specified duration of "heard" signal, (6) Immediately following detection, verify specified duration of silence, (7) Upon Reset B, sample PCM and determine if tone or silence is present, using software threshold. Save history of samples (in all cases of detection) and continuously analyze in order to detect tone cadences or presence of voice, send report to SBD when analysis is complete, (8) Return to Reset C state. Analysis is done by obtaining a "count" of "heard" or "quiet" samples. Based on the duration of the sample, it can be determined if the sample corresponds to a known cadence or if it would most likely be voice. By storing a history of both counts and the corresponding cadence, it is possible to accurately detect any of the possible tones (busy, reorder, dialtone...) and the occurrence of voice.
