Tester and method for testing test environment controllable multi-directional fine motion fatigue

The invention discloses a tester and a method for testing test environment controllable multi-directional fine motion fatigue. The tester comprises a vertical fine motion mechanism and a transverse fine motion mechanism, wherein the vertical fine motion mechanism consists of an electromagnetic excitation actuator, a force transducer I, an upper clamp for clamping a spherical upper test piece and the like; the transverse fine motion mechanism consists of a lower clamp for clamping a planar lower test piece, a force transducer II, a piezoelectric ceramic actuator, a longitudinal and transverse two-dimensional moving platform and the like; the vertical fine motion mechanism and the transverse fine motion mechanism are covered by a lower atmosphere cover and an upper atmosphere cover to form an atmosphere control space; and the periphery of the lower clamp is provided with a liquid medium groove higher than the planar test piece. Through the tester, a tightly matched friction pair can carry out multi-directional fine motion in a specific atmosphere and/or a liquid environment controlled artificially, thus the multi-directional fine motion frictional wear performance of a material under the specific environment condition is tested really and accurately, an accurate and reliable proof is provided for related design, use and maintenance of machinery and bioengineering, the properties of equipment and apparatuses are improved, and the service lives of the equipment and the apparatuses are prolonged.

Dual Action Scooper for clumping and non-clumping cat litter

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. A further aid to performance of the tool being shoved through soiled cat-litter, includes acutely up-turned blade sides; both set slightly back from the actual frontal-sides of the scooping-blade. This particular formation being discovered to function most effectively, providing minimal disturbance to surrounding cat-litter, while very precisely shaving away waste cat-litter. Generic-variations include a preferred 2-piece construction, embodying a stainless-steel blade portion, permanently locking into a retention-groove formed into the aftward injection-molded plastic-body forming the side-walls of the essential containment-bowl; including an integral handle member thereto.
