Abstract: ABSTRACT OF THE DISCLOSURE           A circuit detects the state of a heart by monitoring the continuous time average of the ratio of high slope to low slope ECG segments and effects cardioversion if a malfunction is indicated by such time average ratio exceeding a predetermined threshold.  The circuit comprises an ECG monitor for sensing ECG signals from the heart, signal shaping circuitry for generating the slope of the sensed ECG signals by providing an approximation of the derivative of the input ECG, circuitry for discriminating between high slope and low slope segments, averaging circuitry for continuously time averaging the ratio of high slope to low slope segments, a threshold detector for determining whether such time average ratio of high slope to low slope segments is within predetermined threshold limits indicative of normalcy and circuitry for effecting cardioversion if said ratio is outside such threshold.

Abstract: ABSTRACT OF THE DISCLOSURE         Individual coupling members, molded from synthetic resin onto a support tape and straddling an edge thereof are removed, e.g. to enable the mounting of a slider, the stitching of the tape to a fabric or other carrier or for the formation of end-stop members, by applying orthogonal to the stringer plane a pressure causing plastic deformation and flow of the material of the coupling member which results in a spreading of the fastening shanks thereof.  The tape is then withdrawn from between the legs or shanks which have been thus spread apart or the coupling member is with-drawn from the edge of the tape generally in the aforemen-tioned plane.

Abstract: ABSTRACT OF THE DISCLOSURE            The apparatus has a flat, flexible concave/convex tape retractably coiled into a spool having a housing which is mounted on a suitable gimble.  The gimble is fixedly mounted on the towing vehicle so that the spool axis is horizontal.  A suitable eyelet is provided on the end of the tape so that the eyelet is substantially above the ball hitch when the tape is fully retracted.  On the towed vehicle, a vertical rod is disposed aligned above the ball socket and the rod is adapted to receive the eyelet. the gimble allows the spool to rotate about a vertical axis and also allows the spool housing to pivot about another horizontal axis spaced above the spool's axis.  A micro-switch is provided which responds to tape tension when tape is withdrawn from housing, and a potentiometer is provided which relays responses to horizontal rotation of the housing.  A display, in the form of a meter, is provided in sight of the operator of the towing vehicle, which meter measures the potentiometer setting and a display in the form of an indicator light is provided which responds to the micro-switch to indicate when the tape is fully retracted or withdrawn, i. e., off when retracted, on when withdrawn.

Abstract: A METHOD OF FORMING AN INTEGRATED        CIRCUIT REGION THROUGH THE COMBINATION OF          ION IMPLANTATION AND DIFFUSION STEPS               Abstract A region in an integrated circuit substrate is formed by first ion implanting impurities of a selected conduct-ivity-determining type into a semiconductor substrate through at least one aperture in a masking electrically insulative layer, and then diffusing a conductivity-determining impurity of the same type through the same aperture into said substrate.     The method has particular application when the elec-trically insulative layer is a composite of two layers, e.g., a top layer of silicon nitride and a bottom layer of silicon dioxide and the aperture is thus a pair of registered openings respectively through said silicon nitride and silicon dioxide layers, and the aperture through the silicon dioxide layer has greater lateral dimensions than that in the silicon nitride layer to pro-vide an undercut beneath the silicon nitride ion implanta-tion barrier layer.

Abstract: SEMICONTINUOUS LARGE ROUND  BALING METHOD AND MACHINE     ABSTRACT OF THE DISCLOSURE           Semicontinous formation of round bales is permitted by positively capturing material introduced into the bale-forming chamber of a round baler after ejection of the last-formed bale and while the web normally defining the chamber remains displaced from its forming position.  In one embodiment, the crop-capturing function is performed by a grid comprising a plurality of parallel, upwardly arcuate, elongate bars forwardly mounted on the baler for swinging movement about a transverse axis toward and away from the lower apron of the chamber.  Another embodiment employs rearward-ly mounted, vertically swingable grid of parallel, substantially rectilinear,elongate bars to positively retain crop material in the chamber.

Abstract: ABSTRACT OF THE DISCLOSURE        Most valve assemblies used in water closet tanks are relatively bulky and often interfere with the operative action of the tank.  Furthermore, such valve assemblies are noisy in operation and "wire drawing" effects cause consider-able wear of the valve seat and/or valve.  This device in-cludes a flexible diaphragm engageable with an annular valve seat and acting as a valve between the water intake and the interior of the tank.  A spherical segment cam is mounted in the assembly operatively connected to a float and connecting rod moving reciprocally.  The cam operates a plug sliding reciprocally in the body of the valve assembly, said plug en-gaging the diaphragm and controlling the opening and closing of the diaphragm with the valve seat.  The mechanical advan-tage of the spherical segment cam gives a positive closing action plug minimizing the "wire drawing" effect and the construction of the diaphragm and associated parts eliminates thumping and hissing during the closing action.  An adjust-able volume water trap feed is incorporated in the valve assembly so that the amount of water passing through to the water trap is adjustable within limits.

Abstract: ABSTRACT        An automatic heat control apparatus for use with an electric heating element in a kiln or the like comprises a first power controller having a plurality of on and off intervals. The first controller supplies electric current to the kiln heating element during its on intervals, and further includes means for adjusting the duration of the on intervals relative to the off intervals. A constant speed electric motor is mechanically coupled to the first power controller for gradually increasing the duration of the on intervals and decreasing the duration of the off intervals; such control ensures that the temperature inside the kiln increases very gradually to lessen the risk of breaking the ceramic material being fired. Furthermore, the average speed of the motor may be controlled by means of a second power controller, similar to the first controller, having a plurality of on and off intervals which intermittently energize the motor for rotation thereof. By adjusting the duration of the on interval relative to the off intervals of the second controller, the average speed of rotation of the motor may be selectively varied to control the rate of increase in the duration of the on interval in the first controller.

Filed: 1978-10-05
Granted: 1979-07-31
Abstract: ABSTRACT       A particular range of glass compositions in the soda-boro-silicate glass system has been found to be particularly suitable for ultra-low loss dielectric optical waveguides. The composition range is indicated in Fig. 1 of the specification.  By preparing such glasses in a reducing atmosphere (0-2% CO in CO2) and adding about 1% As2 O3 to the melt attenuation coefficients due to copper and iron can be minimized.  The water content of the glass can be reduced by bubbling dry CO in CO2 through the molten glass.  Glasses containing less than 30% Na2O by weight have the lowest losses.  Using glasses of this type dielectric optical wave-guides having an insertion loss of less than 14 dBKm-1 have been made.
