Abstract: A method of incorporating small graphs on to pages of text or calculations by using small adhesive-backed appliques or labels which have been pre-printed with a graphical coordinate grid. These appliques eliminate the necessity of a separate piece of graph paper or the tedium of drawing or gluing a coordinate grid directly on the report or calculation page.

Abstract: A hydraulic circuit for pitch and tilt control of a dozer blade attached to push arms on a vehicle with a pitch ram connected between one push arm and the blade and a dual actuator consisting of a second pitch ram and a tilt ram connected at their head ends. A pitch valve directs hydraulic fluid to and from the pitch rams with a diverter/combiner valve interposed therebetween to assure a flow of fluid either to said rams or from said rams at equal rates. Pilot-operated check valves hydraulically lock the pitch rams until opened by pressure directed from said pitch valve. Tilt and lift valves directs fluid pressure to and from the tilt ram and a lift ram respectively with regeneration capability for both tilt and lift functions.
