  • Patent number: 6234549
    Abstract: An improved hand-held two-stage cat-litter scooper tool critically configured to more effectively segregate and lift-away wet cat-litter, without causing migration into, or disturbing clean dry areas. The planar leading-edge of the scooping-blade portion, is formed to either a 90-degree triangular, or transversely-square, plan-view shape; either shape thus able to project closely into the corners of a conventional cat-litter box. The rear portion of either scooping-blade includes an approximate 40-degree transverse-bend, creating an aftward containment-bowl area, effectively holding wet cat-litter when the rearward projecting handle is tilted down (the scooping-blade thus tilting upward) after a horizontal forward scooping motion. The handle is arranged along the medial longitudinal-axis of the tool, angling upward at approximately 45-degrees relative to the plane of the scooping-blade, facilitating the special “tilt-loading action” without dragging of one's hand into the cat-litter.

  • Patent number: 6107558
    Abstract: The notion of a reliable semi-automatic page-changer apparatus has heretofore been elusive to inventors, however with the event of a major new handling technique, a practical solution is herein introduced. Predicated upon the principle of establishing a modular standard for the viewed paper, facilitating either sheet-music for musicians or text-pages for speakers. This involves generally utilizing the US/81/2.times.11-inch format, or the european A4/29.7.times.21 cm format, whereby any pre-existing graphic-copy can be readily and economically transferred thereto via convenient photocopy machine process and via a special hangeer-hole device, overcoming the usual disfunctional predisposition toward inter-clinging of the stacked pages. Generally using a foot-operated sequencing-switch, the instant page is transferred via a novel spindle-conveyer to a holding-stack; enabling viewing of consecutive pages either at their originating elevated position or at their final landing position there below.

  • Patent number: 6025775
    Abstract: The notion of an easily retrofitable passive lighting-safety device designed to be generally installed into the existing rear lighting wiring-circuit of any motor-vehicle from motorcycles to cars and trucks, --so as to significantly boost a following driver's visualacuity cognition threshold of awareness regarding the state of a leading vehicle's sudden breaking procedure. The invention provides an intense quasi-precognitive white-light "flashback" alerting effect, preferably appearing (particularly under nighttime conditions) as a nearly subliminal approximate 100-200/millisecond flashback of visually non-deacclimating "white-light", emanating from a vehicle's existing back-up lights (or integrated with the DOT high-center brake-light). The effect being to essentially arouse a following motorist's attention to the simultaneous light-up of the preceding vehicle's stoplights. Regardless as to how long braking action continues, the so called STOPWHITES.TM.

  • Patent number: 5918881
    Abstract: The invention sets forth an improved procedure and facile supporting apparatus, enabling players in a game for example, to make unbias determination by sole virtue of chanch, (as a random pointer-device employed in place of a traditional spinner), as to whom shall be the player selected for virtually any imaginable purpose. The apparatus is a platonic-solid,--that is, having equal faces, equal vertices, equal dihedral-angles between the faces.
