Abstract: MULTIPLE SLOPE IGNITION SPARK TIMING CIRCUIT                 ABSTRACT       A multiple slope ignition spark timing circuit for an internal combustion engine is disclosed which electronically provides a spark timing signal having a piecewise linear advance angle versus engine speed characteristic.  A mag-netic pick-up sensor produces an AC signal having a frequency proportional to the rotational engine speed.  This AC signal is coupled to a programmable voltage slope generator which generates a variable slope voltage that is used to produce the phase difference (advance angle) between a spark timing signal and the AC input signal.  An independent timer apparatus produces various timing pulses which result in changing the advance angle versus engine speed character-istic at various predetermined engine speeds.  An engine vacuum sensor adjusts the slope produced by the voltage generator and thereby results in a fixed amount of vacuum advance angle being added to the spark timing advance angle versus speed characteristic. The spark timing signals pro-duced by the multiple slope ignition spark timing circuit are then used to ignite the fuel mixture in the cylinders of the internal combustion engine when the pistons are at desired predetermined positions in accordance with the engine speed and vacuum pressure.

Abstract: VAPOR PRESSURE REGULATOR FOR A  VAPORIZED LIQUID FUEL SYSTEM     ABSTRACT OF THE DISCLOSURE         A vapor reservoir adapted for use in conjunction with a vaporized liquid fuel system for an internal combus-tion engine is disclosed.  The reservoir includes a movable wall member cooperative with means defining a housing to establish a variable volume vapor storage space.  The movable wall member is referenced to the pressure of the air immediately upstream from the intake to the air and fuel metering portion of the engine.  The housing includes a generally downwardly depending condensate collecting and return section.  Vapor delivery conduits are positioned within the housing and support a thermally floating finned member operative to disperse vapor delivered to the vapor reservoir.  The movable wall member is provided with position sensing means operative to provide an input to an electrical circuit for controlling the rate of vapor delivery to main-tain a predetermined quantity of vapor within the vapor space.         The electronic circuitry is operative to control a liquid fuel delivery means to provide quantities of liquid fuel to a liquid fuel vaporizer for changing the vapor storage space of the vapor reservoir.  The electrical circuit is operative to vary a threshold voltage in response to the sensed position of the movable wall member.  The variable threshold voltage is compared to a saw tooth wave train to generate a variable duration voltage pulse in order to selectively control the coarse liquid fuel delivery means.

Abstract: ABSTRACT OF THE DISCLOSURE          A self-expanding low density catamenial tampon made up of intermeshing loops of resiliently deformable strip material.  The intermeshed loops are arranged in the form of an openwork spheroid with the strips crossing at the top and bottom of the vertical axis of the spheroid.  The strips at the bottom crossing area are secured together by a with-drawal string.  A special inserter for the tampon is also described, the inserter is comprised of a tubular tampon-containing member and an internal pusher element in slidable association with the tube member and having an axial tampon-supporting frontal extension thereon.  When combined with the inserter the spheroidal tampon is collapsed with the top and bottom crossover areas juxtaposed.  The elongate tampon-supporting pusher element is positioned at the bottom crossover point and the rest of the tampon is folded down around the element to form the tampon into an inverted cup shape.  The cup-shaped tampon is then pushed into the other tubular member by the pusher element.  The tubular member is of lesser diameter than the uncompressed folded tampon and therefore holds the tampon in resiliently compressed condition therein.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for, and a process of, sector engraving metal elements is disclosed. The apparatus includes an engraving roller having a particular pattern formed thereon and a workpiece mounting system which is capable of translational movement within two mutually orthogonal directions. When the engraving process is to be performed, the engraving roller is held in contact with the workpiece, and as a result of a first translational movement of the workpiece mounting system in a first direction, a predetermined sector of the engraving roller is caused to contact a predetermined portion of the workpiece whereby a predetermined portion of the roller pattern is reproduced upon the workpiece. Movement of the workpiece mounting system in the second direction causes another sector of the engraving roller to be aligned with another portion of the workpiece whereupon repeated movement of the workpiece mounting system in the first direction serves to reproduce a new portion of the pattern upon the new portion of the workpiece.

Abstract: ABSTRACT OF THE DISCLOSURE         A vibrating machine, such as an oscillating conveyor, vibratory feeder, or vibratory screen, is mounted to a plurality of supports by a suspension that isolates machine vibrations from the supports.  The sus-pension includes a plurality of U-shaped stirrups extend-ing transversely beneath the machine at intervals spaced longitudinally of the machine.  Each U-shaped stirrup extends between a pair of opposed supports to which the stirrup is mounted for pivotal movement about an axis of rotation that extends transversely of the vibrating machine.  This axis of rotation is along or near the axis of the instantaneous center of rotation of the stirrup. The stirrups support the vibrating machine at points spaced below the axis of rotation, and vibrations in a direction longitudinal of the vibrating machine impart a rotational motion to each stirrup.  Thus, such vibrations are not transmitted to the supports.  In a preferred embodiment, resilient bushings are fitted within the U-shaped stirrups coaxial with their axis of rotation, vibration dampening resilient means are provided for mounting the vibrating machine upon the stirrups, and the stirrup surfaces supporting said resilient means inter-sect an axis that is parallel to the axis of rotation and that passed through the region of the center of percussion of the stirrup about the axis of rotation.                             -1a-
