Abstract: TEST SET AND METHOD FOR THE DETERMINATION OF FREE SPECIES            Abstract of the Disclosure Disclosed is a process for determining the con-centration of an unbound species, e.g., thyroxine, cortisol, testosterone, or digoxin, in a liquid sample containing the species and protein.  The sample is incubated with antibody spe-cific to the species to be detected and a distinguishable analo-gue of the species, both of which are separated from the sample by semipermeable membranes capable of excluding the passage of natural protein and antibody but which allow passage of the spe-cies and its analogue.  Preferably, the antibody and analogue are contained in semipermeable microcapsules.  Free species in the sample permeates the membranes and competes for sites of attach-ment to the antibody with the analogue.  The antibody and free species are then separated.  The amount of analogue present either in association with the antibody or in the remainder of the reaction system is indicative of the level of free species originally present in the sample.

Abstract: INTEGRALLY CHANGEABLE KEY COMBINATION TRANSVERSE              PIN TUMBLER LOCK                 ABSTRACT OF THE DISCLOSURE         A pin tumbler lock employs elements which allow the key combination to be selectively changed without removing the lock from its installed position or disassembling or replacing any part of the lock.  The lock comprises a housing member, a sleeve member axially and rotationally positioned within an interior opening of the housing member and a plug member rotatably received within an interior opening of the sleeve member.  Operation of the lock requires release of the two shear surfaces defined by the contact surfaces of the sleeve, housing, and plug members.  Transversely parallel extending bores formed through the three members receive elements of a locking stack assembly.  The locking stack assembly includes tumbler pins, driver pins, change wafers and locking pins.  Upon insertion of a proper key, the interfaces between tile locking stack elements are positioned at the two shear surfaces thereby allowing operation of the lock.  The sleeve member additionally includes chambers containing change wafers, and the relative position of the locking pins can be selectively changed in the locking stack assembly upon positioning the sleeve member in a combination changing position.  Means inter-connecting the housing, sleeve and plug members releases one of the shear surfaces by relative rotational movement prior to the release of the second shear surface by relative axial movement. Magnetic elements of the locking stack assembly resist separation of the locking stack elements during insertion and removal of the key.  A set key having a reciprocating projection member may be employed to change the lock combination.

Abstract: ABSTRACT OF THE DISCLOSURE           In a coal liquefaction process including recyle of a product slurry comprising normally solid dissolved coal and mineral residue, the minimum slurry recycle rate is determined by a pumpability constraint on the solids level of the slurry contained in the feed coal mixing vessel.  If the solids level in the feed coal mixing vessel rises above the constraint level, the slurry recycle rate must increase.  For coals which generate a high mineral residue content, adequate dilution of the slurry in the feed coal mixing vessel requires the slurry recycle rate to rise to an economically impracticable level.  In the present process, a portion of the product slurry is passed through a hydroclone to produce a second recycle slurry comprising hydroclone overflow.  It is shown that deployment of the second recycle slurry accomplishes selective recycle of relatively small mineral particles.  The process is performed with an extraneous catalytically active mineral whose particles upon recycle under the conditions of the process develop a mediam diameter as small as or smaller than the particles of recycle mineral residue generated from the feed coal, even though the extraneous particles as fed may have a larger diameter than the particles of mineral residue generated from the feed coal.  The reduction in size upon recycle of the extraneous particles will tend to increase the concentration of these particles in the hydroclone overflow slurry.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides head-coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators.  The apparatus provides a display projected onto the inside of a part-spherical shell which surrounds the pilot and carries a retro-reflective screen.  The displayed scene covers an area of interest dependent upon craft position and heading and viewer's instantaneous line of view.  The image generator may be of the computer generated image, laser-scanned model or closed-circuit television type.  Multiple images are required for stereoscopic viewing or for more than one viewer.          Line scanning apparatus is cockpit-mounted; line image is trans-mitted by fibre optic light guide ribbon and frame scan apparatus is mounted on a helmet worn by the viewer.  A sensor measures heat/helmet movement to permit voluntary scanning of a wide angle simulated view from the craft.  The projected image is divided into zones each zone using separate 1ine-scanning means and fibre optic light guide.  The frame scanning projector means provides simultaneous frame scanning of each zone.

Abstract: Abstract An inverter-motor combination is regulated in accordance with this invention to minimize deterioration of the power factor as the inverter is reduced from 100% load.  This is accomplished by sensing the motor current and providing a control signal to regulate the inverter output frequency in accordance with a first function, representing virtually linear decrease in frequency as the load is reduced from 100% to substantially 70% of full load.          A constant voltage stage is connected to regulate the d-c bus controller to provide a modified control signal for regulating the d-c bus level according to a second function, maintaining the d-c bus voltage at virtually 100% while the load is reduced to 70%.  Thus the d-c bridge is not phased back and the power factor of the complete system is not degraded over this described operating range.  This invention differs from earlier systems in that as the motor speed is reduced below base speed or 100% load, the frequency of the inverter output voltage is reduced but the amplitude of this voltage remains substantially constant in the region from about 70% load to 100% load.
