Abstract: ABSTRACT         A new and useful particulate magnesium phosphate product (MGP) and method of use therefor are disclosed for removing ammonia from aqueous solutions, e.g., recirculating dialysate solutions and intragastrointestinal fluids as may result from the hydrolysis of urea.  This particulate magnesium phosphate product (MGP) acts as a remarkably effective scavenger wherein under equilibrium conditions only about six (6) grams of the novel product are required to bind the ammonia (more exactly, ammonium ions) liberated from one (1) gram of the urea, a result far superior to traditional zirconium phosphate (ZP) prior art materials which under ideal conditions require about 17 - 20 grams of ZP per gram of urea.  The novel particulate magnesium phosphate product can be exploited in one embodiment as a replacement for the older ZP materials used to remove ammonia produced by enzymatic hydrolysis of urea in recircul-ating dialsysis systems utilizing disposable cartridges.  In another embodiment, in a new encapsulated product (comprising a water-insoluble, membranous wall, permeable to urea and/or ammonia and water, while impermeable to urease enzyme, wherein the wall surrounds a core of urease and the novel particulate magnesium phosphate product) is disclosed, which can also be used as an in vivo or in vitro scavenger.  This particulate MGP product can also be used for the removal of ammonium ions either produced by enzymatic or non-enzymatic hydrolysis of urea or proteins or amino acids or available as NH4+ from its native source.  A new method is also disclosed for the prep-aration of the novel particulate magnesium phosphate product.

Abstract: TWO-PULSE TACHYCARDIA CONTROL PACER              Abstract of the Disclosure There is disclosed an improved pacer for con-trolling tachycardia.  Prior art pacers of this type generate a stimulus a short time, known as the "initial delay", after confirmation of tachycardia.  The initial delay is "scanned" from one extreme to the other until the condition is terminated.  In some pacers of this type, a second stimulus is generated at a fixed time, known a  the "coupled interval", after the first stimulus; the second stimulus sometimes terminates the condition even if the first does not.  In the improved pacer, the coupled interval is scanned as well as the initial delay.          Also, the time parameters which are successful in ter-minating the condition are stored so that upon confirmation of another tachycardia event, the previously successful time parameters are the first ones to be tried.  The unit also allows tachycardia to be induced by the physician so that the parameters which are programmable can be ad-justed for optimum performance following a subsequent naturally occurring tachycardia confirmation.

Abstract: APPARATUS AND METHOD FOR MEASURING              THE CONCENTRATION OF PARTICLES IN A GAS          Abstract of the Invention The invention provides an apparatus and method for measuring the concentration of particles in a gas using an electrode disposed within but electrically insu-lated from an electrically-conductive conduit member, a current measuring device and means for maintaining the conduit member and the electrode at substantially the same potential. Flow of gas containing charged particles along the conduit induces a current passing from the electrode through the current measuring device.   If the concen-tration of particles in the gas becomes excessive, the current measuring device activates a warning device or takes other action to prevent damage to any gas-consuming device attached to the apparatus.  The apparatus might include an optional ionizer up-stream of the electrode to charge the particles in the gas.

Abstract: ABSTRACT         A rolling mill roll assembly comprising an inner cylindrical mandrel and an outer cylindrical sleeve bonded thereto with glue containing grit particles.  Wire is spirally wound around the outside of the mandrel and secured thereto with the glue.  The sleeve has an inner diameter substantially equal to the outer diameter of the mandrel plus two times the wire thickness.  The grit particles are thicker than the wire.  The sleeve is heated to ther-mally expand the sleeve sufficiently to clear the grit particles when slipped over the mandrel.  As the sleeve cools, the wire acts to center the sleeve on the mandrel, and the grit particles, which are harder than both the sleeve interior and the mandrel exterior become embedded in both to enhance the glue bond.  The sleeve is substan-tially devoid of hoop stresses.

Abstract: ABSTRACT OF THE DISCLOSURE        A semiconductor hot electron transistor of the tunneling emitter type has an emitter layer, an insulating layer, a metallic or metallically conductive base layer, and a collector layer.  The emitter layer is formed by an inversion layer generated in the channel region of a field effect transistor integrated on a semiconductor substrate between the source and drain regions of the field effect transistor.  The base layer of the hot electron transistor includes at least one portion of the gate electrode of the field effect transistor.  The hot electron transistor is operated by forming a depletion zone between the source and drain region of the field effect transistor by switching a voltage source connected to the gate electrode of the field effect transistor (which forms the base layer for the hot electron transistor), the voltage source alternating between two values one of which is above the threshold voltage for the field effect transistor.  The hot electron transistor may also be operated by varying the source voltage as a function of an input signal.
