Abstract:

A hydraulic grapple apparatus and method for use of the same are disclosed. In one embodiment, the hydraulic grapple apparatus includes a support frame for attachment to a skid steer loader. The support frame has upper and lower guide tracks arranged in vertical alignment with each other and spaced apart in order to define an open channel therebetween. First and second grapple jaws are mounted on the upper and lower guide tracks for lateral movement along the support frame. First and second double-acting hydraulic cylinders are disposed in the open channel and coupled to the support frame. The first and second double-acting hydraulic cylinders independently actuate the first and second grapple jaws, respectively.

Abstract:

A beam separating prism system for an imaging system having two pairs of prisms, each prism having a 30, 60, and 90 degree triangular cross section and being provided with a partially reflecting region situated between the common boundary of the pair. A nonreflecting entry surface of one pair receives light which is both not focused and not parallel as reflected from a document. The light received at the entry surface is separated into three light components by the prism system. The exit axes of two light components are parallel and the exit axis of the third light component is at an angle of approximately 60 degrees to the other exit axes. The light is received by the pair of prisms having the entry surface and intercepted by the partially reflecting region of the pair. The remaining light is transmitted by the partially reflecting region to form a first component which is then reflected along an exit axis. The light reflected by the partially reflecting region is deflected by the rear of the entry surface toward the other pair of prisms at an angle of approximately 60 degrees to the partially reflecting region of that other pair of prisms.
