Abstract: An apparatus is disclosed for attachment to a jack including a first axle. The apparatus includes a fulcrum wheel disposed on a second axle, the second axle being connected directly or indirectly to the first axle. A lever has a first end connected directly or indirectly to the second axle and a second end having a terminus. A first line intersects the first axle and second axle. A second line intersects the second axle and the lever terminus. The first and second lines meet at an obtuse angle. In another aspect, an apparatus is disclosed including a jack having a first axle, an extension member, and a fulcrum wheel is disposed on a second axle connected to the extension member. A lever has a first end attachable to the extension member proximate the second axle. A method of moving a jack relative to a ground surface is also disclosed.

Abstract: A device system includes a transmitter assembly and a receiver assembly. The transmitter assembly includes a frequency transmitter having an antenna and a first plurality of electrically conductive elements. The receiver assembly includes a frequency receiver having an antenna and an annunciator. Immersion of at least a portion of each of the first plurality of conductive elements in water causes the frequency transmitter to transmit a frequency via its antenna to the antenna of the frequency receiver, thereby causing a first annuciation by the annunciator.

Abstract: A reliable efficient rotary valve apparatus for internal combustion engines, configured for ease of installation and maintenance. Rotating valve apparatus controls transfer of intake and exhaust gases between intake and exhaust manifolds respectively of an internal combustion engine and the respective combustion cylinders thereof. Intake and exhaust portions of the rotary valve assembly are isolated by simple seal members. Activating means, responsive to rotation of the rotatable valve member, create positive fluid-flow transfer of gaseous currents through the rotating valve member. Spring biased, pressure equalizing plunger seal apparatus increases reliability and longevity of use of the rotary valve apparatus and maintains proper seals for fluid-flow passage between the rotating valve member and individual compression cylinders of the engine.
