Abstract: Abstract of the Disclosure An externally cooled, absorption engine apparatus and method,  the  apparatus including a closed cycle system having a first fluid and a second fluid, the first fluid  constituting  a working  fluid  and  having  a relatively lower boiling point while the second fluid constitutes a solvent for the first fluid and has a relatively higher boiling point and a relatively high degree  of  absorptivity  for  the  first  fluid.   The apparatus further includes a distillation column,  a superheater,   a  mechanical   expansion  engine,   an externally cooled absorption column, and heat exchange apparatus.  The distillation column separates the first fluid or working fluid from the solvent with heat energy supplied  by  an external  combustion source and the superheater increases the thermal energy thereof prior to passing the working fluid through the mechanical expansion  engine.   The  mechanical  expansion  engine converts thermal energy in the working fluid vapor to mechanical energy. Importantly, the backpressure to the mechanical expansion engine is significantly lowered by absorbing the working  fluid with solvent  from  the distillation column and the efficiency of the same is substantially enhanced by cooling the solvent and also by removing heat  of absorption through an external coolant source.

Abstract: ABSTRACT OF THE DISCLOSURE   An optical system for a copying device is disclosed which scans a document lying in an object plane by means of a pivoting mirror and projects an image of the document onto the surface of a photoreceptor drum. By rotating the projection lens while simultaneously moving an aperture slit in a direction of movement opposite to the movement of the drum, a condition is constantly maintained wherein the object plane, lens plane and image plane are maintained parallel thereby eliminating field tilt. With this configuration, the image is also precessed onto the drum providing a precession distance which can be used to relax constraints normally imposed by scan return conditions.

Abstract: TITLE CROSS IDENTIFICATION SYSTEM AND LOCK        ABSTRACT OF THE DISCLOSURE       The system described is a positive cross identification system finding use in assuring that the proper medicaments are used for the proper patient.  In this system, a patient's identification (I.D.) number is read by an optical scanner.  Next, the I.D. number of the intended recipient on medicament container label is read by the optical scanner and the identification numbers compared in an electronic comparator.  If comparison is indicated, an electronically actuated lock on the medicament container is unlocked.       The lock described includes a lock body with a receptacle into which a split locking pin is introduced.  An actuating pin spreads the members of the locking pin such that the locking pin cannot be removed.  The locking pin can be removed only by withdrawing the actuating pin from the split members so that they are allowed to come together and be withdrawn from the aperture.  Withdrawal of the actuating pin is accomplished by a solenoid actuated by the output of the comparator.

Abstract: ABSTRACT OF THE DISCLOSURE      A nuclear radiation actuated valve for a nuclear reactor.  The valve has a valve first part (such as a valve rod with piston) and a valve second part (such as a valve tube surrounding the valve rod, with the valve tube having side slots surrounding the piston).  Both valve parts have known nuclear radiation swelling characteristics.          The valve's first part is positioned to receive nuclear radiation from the nuclear reactor's fuel region.  The valve's second part is positioned so that its nuclear radiation induced swelling is dif-ferent from that of the valve's first part.  The valve's second part also is positioned so that the valve's first and second parts create a valve orifice which changes in size due to the different nuclear radiation caused swelling of the valve's first part compared to the valve's second part.  The valve may be used in a nuclear reactor's core coolant system.

Abstract: ABSTRACT           A pipe connector comprises a tubular box member which is telescopically engageable with a tubular pin member, the members having corresponding frusto-conical inner and outer peripheral surfaces which over-lie one another when the members are fully engaged together.  To axially lock the members together, the frusto-conical surfaces are provided with pairs of interengageable annular projections and grooves.  The projections and grooves have varying axial extents and spacings so that, as the members are telescoped together, in all intermediate positions of the members, there is sufficient contact between crests of the grooves and surfaces between the projections to prevent inadvertent engagement of a projection with a groove.

Abstract: DIESEL ENGINE FUEL LIMITING SYSTEM          Abstract of the disclosure:          A fuel limit controller includes a computer supplying a commanded absolute EGR control pressure that is a measure of fuel supplied per diesel engine revolution.  An absolute EGR control pressure equal to the commanded absolute pressure is generated from a subatmospheric pressure source and atmospheric air so that the absolute EGR control pressure is limited to atmospheric pressure.  Fuel per engine revolution is limited to the value represented by the absolute EGR control pressure so that the fuel limit is auto-matically compensated for altitude variations.  The rate of change in the fuel limit in response to changes in the absolute EGR control pressure is limited to delay increases in fuel to match the time to purge excess exhaust gases from the engine intake manifold.
