Abstract: ABSTRACT OF THE DISCLOSURE         In a long vertical shaft activated sludge bio-reactor for the treatment of waste water and the flotation/ separation of solids therefrom, an improvement is provided whereby fluctuations in flow through the bioreactor are maintained level without the use of complex control mecha-nisms and whereby separation from the effluent of dispersed air bubbles occurs directly in the flotation/separation vessel rather than in the shaft or an auxiliary vessel.          The improvement provides for the installation of a holding reservoir between the shaft and the flotation/separation vessel.          Influent passes through the reservoir on its way to the bio-reactor and some make-up effluent from the flotation/separa-tion vessel is directed into the holding reservoir as the level of liquid in the reservoir falls.  In addition, means are provided in the separation/flotation vessel to split off large dispersed gas bubbles which would otherwise disrupt sludge flotation.

Abstract: 11.               OPTICAL FIBERS CONTAINING         ALUMINUM METAPHOSPHATE          Abstract of the Disclosure This invention relates to optical fibers containing aluminum metaphosphate.  In a specific embodiment, aluminum metaphosphate, doped with from 10 to 30 mole percent of diboron trioxide, is found to yield an optical fiber which combines the desirable properties of both high numerical aperture and low material dispersion. The fiber is nonhygroscopic and has a high melting temperature.  The index of refraction of the glass may be lowered by doping with silicon dioxide.  Consequently, a graded fiber may be made by increasing the concentration of silicon oxide from the core to the cladding.  [FIG. 2].

Abstract: LAY-IN LUG WITH CONDUCTION PAD            Abstract A lay-in lug which may be sued for a grounding connection by securing it to a conductive bushing, or the like, is disclosed.  The lug comprises a body member for providing strength and rigidity and a conducting member, supported by the body member, for providing a low resistance conduction path.  The conducting member is in direct contact with both the laid-in wire and the bushing, or the like, whereby a low resistance conduction path is provided between the wire and the bushing.  First and second clamping means secure the lug to the bushing and hold the wire in contact with the conducting means, respectively.  The conducting member may be selectively removable from the body member and may include a turned-up lip for helping to retain a wire in contact therewith.  The conducting member may also include means for inducing slight deformation of a wire compressed there against to increase the pull out force required to extract the wire.  The conducting member adjusts, by mild deformation, to bushings of various configurations.

Abstract: Abstract:         A voltage conversion and regulation system and method of same utilizing pulse-width modulation to vary the periodic energization of a tuned circuit employed to drive a transformer and an associated rectifier.  The tuned resonant circuit is periodically energized from a DC source at a fixed rate but for alterable periods of time during each cycle so as to produce in the tuned circuit an alternating current of fixed frequency for subsequent transformation and rectification into a DC voltage of predetermined, regulated level.  A pulse-width modulator is connected in feedback-loop fashion between the system output terminals and switch circuitry employed to effect the periodic energization.  Varying the length of time during which the switch circuitry is activated responsive to changes in the level of output voltage produces the desired regulating control.

Abstract: ABSTRACT OF THE DISCLOSURE          A distributed CBX system which provides a virtual network between remotely located CBXs is disclosed.  The CBXs are connected to both a voice network and a packet network.  A first CBX may interrogate a second CBX to determine, by way of example, the status of a called station at the second CBX over the packet network.  The second CBX not only provides the status of the called station but also provides, if the called station is clear, the number of a free incoming line at the second CBX.   In this manner, the first CBX can place a call to both an available line and station at the second CBX.  Alternatively, because of facility availability or tariff structures, the call may be originated over common carrier facilities in the reverse direction originating over common carrier facilities from the called party end.

Abstract: Arrhythmia Detection System And Method Abstract The invention relates to an arrhythmia detection system and method for defibrillating the heart of a patient experiencing abnormal cardiac rhythm, wherein the abnormal cardiac rhythm (comprising one of fibrillation, high rate tachycardia, and low rate tachycardia) is first detected, the heart rate is sensed so as to distinguish between fibrillation and high rate tachycardia, on the one hand, and low rate tachycardia, on the other hand, and automatic defibrillation of the heart of the patient is implemented when one of fibrillation and high rate tachycardia is determined.  In one embodiment, base and apical electrodes are connected to a probability density function (PDF) circuit and a rate circuit. When both abnormal cardiac rhythm and excessively high heart rate are detected, defibrillation of the heart of the patient is implemented.  In a second embodiment, a sensing button is also connected to the heart, and a switch is interposed between the electrodes and sensing button, on the one hand, and the interface, on the other hand.  During monitoring of cardiac rhythm by the PDF circuit, the switch automatically connects the electrodes to the PDF circuit, while, during sensing of the heart rate, the switch connects the sensing button to the heart rate circuit. Upon detection of the need for defibrillation, the switch automatically connects the defibrillation pulse generator to the electrodes. Further features include a timed reset capability.
