Abstract: PROPORTIONAL SOLENOID VALVE            Abstract:           A  diaphragm operated  valve  assembly  is controlled by an electromagnetic valve assembly (10) A flat disc armature (22), which forms part of a flux path, is operable in an inner chamber (118) to modu-late the flow between the inner chamber (118) and an exit port (28) in response to an applied magnetic force.  The level of the effective magnetic force is a function of the armature (22) mass, and the pressure acting on the disc surface.   A pole piece (16) ad-jacent to the flat disc armature (22) is slidably adjustable to establish a specified force to actuate the armature (22) to the closed or sealing posi-tion.   This specified force is proportional to the current flow through the winding of the electromagnet-ic valve assembly  (10).   Thus the armature  (22) operates to seal communication between the inner chamber  (118)  and the exit port  (28)  at a given pressure differential as a function of current flow.          The travel distance between the armature and a non-magnetic seal seat (21) has been minimized by spring biasing the armature  (22)  in proximity to the seal seat (22).

Abstract: ABSTRACT OF THE DISCLOSURE     An audio speaker system is disclosed providing improve fidelity of performance from overdamped woofer drivers in small sealed enclosures.  At least two woofer drivers are employed, and are driven electrically in such a manner that the phase difference in the drive signal to the two drivers, or sets of drivers if more than two are employed, will be near zero at the lowest bass frequency and will increase to a value up to 180 degrees at the highest bass frequency which is generally taken as the woofer-midrange crossover frequency.  This aforementioned phase difference in the electrical drive signal to two sets of woofers common to one sealed enclosure improves over prior art by providing increased low-bass acoustic output, less wave interference between the woofers and the midrange drivers, and a smoother input impedance characteristic in the bass frequency region.

Abstract: ABSTRACT     A drilling and thread forming fastener comprising a trailing threaded shank and a pilot end having a trans-verse major axis and a transverse minor axis.  A pair of flutes extend longitudinally in the pilot end whereby to provide a pair of cutting surfaces.  Each of the cutting surfaces is formed arcuately in the longitudinal direction to provide proper rake for drilling the flutes being oriented such that the cutting surfaces lie generally along the plane defined by the major axis of the pilot end and are coterminal with the major axis whereby cutting edges associated with the cutting surfaces describe a circle having a greater diameter than the minor axis when the fastener is rotated.  Drag surfaces are formed by the flutes lying generally along the minor axis and coterminal there-with.  Lands are provided intermediate the drag and cutting surfaces of increasing width in a radial direction from the drag surface to the cutting surfaces whereby the lands will not engage the sidewall of a pilot hole formed by the cutting surfaces.  The improvement resides in that the drag surface is formed arcuately in the longitudinal direction of the fastener in substantially the same arcuate configuration as a said cutting surface to provide clearance for chips of material produced during the drilling process.  The arcuate surface has substantially a constant radius throughout its length and extends from a point adjacent the tip of the pilot end to a point adjacent the threaded shank and is formed at an angle with respect to the cutting surfaces to provide a smooth flow of material through the flutes.

Abstract: Abstract of the Disclosure:           A pair candidate list (73) is formed by selecting minutia pairs with reference to a minutia list (71) showing original position and direction data given for minutiae by principal coordinate systems preliminarily selected on a search and a file fingerprint and those relation data of the minutiae which are substantially independent of the coordinate systems.  It is very likely that the pair candidate list shows coarse pairs because the coordinate systems may not yet be optimally matched to each other.  One of the coordinates systems is transformed by those optimum amounts to provide transformed position and direction data which are decided by the original position and direction data of the minutia pairs of the pair candidate list.  A pair list (86) is formed by precisely selecting minutiae from the pair candidate list with reference to the transformed position and direction data and the original position and direction data given by the other principal coordinate system and to the relation data.  On forming the pair list, an additional minutia list (81) is preferably formed which shows the transformed position and direction data and the last-mentioned original position and direction data together with the relation data.

A push-pull signal having similar polarity voltage excursions is applied to opposite terminals of the load.  Alternate individual terminals of the load which are opposite to the terminals to which the non-idle phases of the push-pull signal are alternately applied are connected to a common terminal via a pair of transistors.  The pair of transistors are driven by an amplified representation of the push-pull input signal.  Since pulse signals are not used to drive the pair of transistors, capacitors need not be used to eliminate switching transients which would otherwise appear, and increased efficiency results.
