Abstract: COMPUTER OPTIMIZED ADAPTIVE SUSPENSION SYSTEM HAVING COMBINED SHOCK ABSORBER/AIR SPRING UNIT            ABSTRACT     A vehicle suspension system in which a computer controls damping and spring forces to optimize ride and handling characteristics under a wide range of driving conditions,  A combined shock absorber/air spring unit is connected between the wheel and frame of a vehicle. The shock absorber includes a hydraulic sensor which provides signals to the computer which are representative of the position of the piston within the shock absorber.  The computer utilizes these signals to control compression and rebound  hydraulic  pressure  regulators  to  produce preprogrammed compression and rebound damping forces that will yield the desired ride and handling.  The air spring may be connected in series with the shock absorber for compression and rebound along the same axis.  Pressure sensors and air pressure inlet and outlet valves are connected to the computer for adjusting the pressure within the air spring to provide the desired spring rate.

Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus and method for identifying individuals through the ocular reflectance pattern from the fundus of the eye.  A fixation target is provided for positioning and focusing the eye of an individual along its visual axis, being centered on the fovea of the eye.  An infrared source provides a substantially collimated source beam of infrared radiation.  A scanner directs the infrared radiation into the fixated eye from a plurality of sequential angularly divergent positions forming a substan-tially circular locus of points substantially centered on the fovea.  The light is reflected in part out of the eye and forms a reflected beam.  A detector measures the intensity of the radiation reflected from the eye at each sequential location, the intensities being recorded as an identification pattern.   At a later date the eye may be presented again to the apparatus in a different rotational position about its visual axis and another pattern generated.  The two patterns will be substantially the same, varying only in the relative start points of the data sequences.  One pattern may be rotated with respect to the other pattern to ascertain that the two patterns match, thus verifying the identity of the individual.

Abstract: IMPELLER PUMP WITH SELF-PRIMING COLUMN ATTACHMENT     Abstract of the Disclosure The combination of a motor-driven impeller pump assembly and a self-priming column attachment.  The column attachment is detachably secured to the pump assembly and includes an elongate shaft exterior which is attached to an impeller in the pump assembly with a detachable connection.  An axial flow inducer is located at the bottom end of the column attachment and serves to lift a fluid in the column towards the impeller.  A balance line conduit extends from a balance chamber located behind the impeller downwards on the extension of the column to the level of the axial flow inducer, thereby serving to lessen axially imbalance forces acting on the impeller pump assembly.  The column also includes a set of straightener vanes to reduce rotational flow through the length of the column.  A double-volute chamber surrounding the impeller serves to radially balance forces acting on the impeller, the motor and their associated bearings.

Abstract: CONTROLLING VISCOSITY OF FABRIC SOFTENING HEAVY DUTY LIQUID DETERGENT CONTAINING BENTONITE            ABSTRACT OF THE DISCLOSURE:         A fabric softening heavy duty liquid detergent compo-sition of controlled viscosity, which does not thicken exces-sively on aging, includes certain proportions of sodium linear higher alkylbenzene  sulfonate, sodium alkyl polyethoxy sulfate, builder salt (highly preferably a mixture of sodium tripoly-phosphate and sodium carbonate), finely divided swelling bentonite, low molecular weight polyacrylate and water. Such product is a stable pourable liquid of desired viscosity, density and pH, convenient for use in washing machines, for hand washing of laundry and for pre-treatment of badly soiled portions of items to be laundered.  The presence of a small percentage of the polyacrylate in the composition prevents the viscosity thereof from increasing on storage to such an extent as would interfere with pourability.

Abstract: ABSTRACT OF THE DISCLOSURE      The front and rear wheel steering device of the present invention not only has a means for allowing the manual selection of a mathematical function which determines the steering angle ratio of the rear wheels relative to the front wheels from a plurality of mathematical functions but also has a means for limiting such a manual selection depending on the condition of the vehicle.  Since manual selection of a mathematical function for the steering angle ratio may not be appropriate under certain vehicle conditions, the device of the present invention limits such a manual selection when the vehicle speed, the vehicle acceleration, the shift position of the transmission, the steering speed or the steering acceleration is greater than a certain value. Thereby, the convenience of the manual selection of the steering angle ratio is preserved yet any undesirable vehicle response from improper manual selection of the steering angle ratio is prevented.
