Abstract: ORGAN CAPTURE DETECTION FOR    ELECTRICAL STIMULATORS    ABSTRACT OF THE DISCLOSURE         A medical stimulator is disclosed in which a number of sensing electrodes are placed along the conductive path of an organ, for example, along the jejunum at a location remote from the natural pacemaker in the proximal duodenum.  The pacing electrodes are positioned adjacent the group of  sensing electrodes and pacing pulses of d frequency higher than the frequency of a natural pacemaker of the organ are applied to the pacing site(s).  In order to be effective, however, the physician using the apparatus must know that capture of the organ has been obtained by the pacing pulses.  The present invention achieves this result by evaluating the sensed pulse signals that are received at each of the sensing electrodes in a timed sequence to determine if pacing of the organ is under the control of the applied pacing pulses.

Abstract: CLOSED FCC CYCLONE SYSTEM     ABSTRACT          The present invention involves a fluid catalytic cracking (FCC) apparatus and process comprising a reactor riser zone, primary and secondary cyclones, connected in series to the riser zone, and a stripping zone.  The riser zone, the primary and the secondary cyclones, and the stripping zone, are placed within a single reactor vessel.  The primary cyclone is connected to the reactor riser zone by an enclosed conduit which prevents random post-thermal cracking of the hydrocarbons after they exit the reactor riser zone.  The secondary cyclone is also connected to the primary cyclone by an enclosed conduit.  Any one or both of the enclosed conduits contain a trickle valve to accommodate sudden increased surges of pressure and of flow of the hydrocarbons and catalyst mixture.  The reactor riser zone is equipped with an opening which allows stripping gases, from the stripping zone, to enter the riser.  The gases can be subsequently conducted through the primary and secondary cyclones to the downstream fractionation means.

Abstract: "ALKYLAROMATIC HYDROCARBON DEHYDROGENATION PROCESS"                              ABSTRACT           A hydrocarbon conversion process is disclosed for the de-hydrogenation of alkylaromatic hydrocarbons such as ethylbenzene or ethyltoluene.  A subatmospheric pressure is maintained in the reaction zone by the use of two separate compressors.  The first compressor pressurizes the vapor phase reactor effluent prior to the final indirect heat exchange step(s) used to partially condense this stream.  The second compressor maintains the vapor-liquid separator which receives the partially condensed reactor eff1uent stream at a subatmospheric pressure.  This facilitates operation of the reactor at a subatmospheric pressure.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides a magnetic bubble memory device comprising a magnetic layer in which magnetic bubbles can be moved and a bubble propagation path defined by a pattern of magnetically soft elements, each of the pattern elements having an asymmetrically crooked or curved shape with an entrance-side segment and an exit-side segment having different lengths.  The pattern elements are arranged on the surface of the magnetic layer at a predetermined period in such a manner that the exit-side segment of one of the adjacent pattern elements is opposed to the outer side of the entrance-side segment of the other pattern element, with a gap therebetween.  The difference in length between the entrance-side segment and the exit-side segment of the pattern element is 10 to 25% of the height of the pattern element.  This bubble propagation pattern has a geometry which is favourable for gaining an increase in density and which can provide a high propagation characteristic.
