Abstract: UPRIGHT FOR LIFT TRUCK            ABSTRACT   A lift truck upright having a fixed upright section, a telescopic upright section, and a load carrier mounted on the telescopic section.  A pair of main lift cylinder assemblies are located adjacent opposite sides of the upright, and a second pair of relatively short free-lift cylinder assemblies are located inwardly adjacent the main lift cylinders, said pairs of lift cylinders being mounted from the fixed upright section and being hydraulically connected in parallel and of such relative size that the free-lift cylinders and main cylinders always actuate in the proper sequence to first elevate the load carrier in free-lift and then the load carrier with the telescopic section.  maximum fork height is attained following travel of the load carrier until it contacts stops at the top of the telescopic section, whereupon continued pressure supplied to the pairs of cylinders causes extension of the free-lift cylinders to transfer hydraulic fluid to the main cylinders to aid further extension of the telescopic section until the main cylinders have traveled full stroke.  The upright is designed such that the free-lift cylinders are readily interchangeable with fixed anchor rods for applications in uprights in which the free-lift feature is not required. These cylinders and the associated hydraulic components can be readily provided as a kit for interchangeable in the field.  A high visibility upright is thus provided in a design which provides substantial free-lift and which is readily interchangeable with an upright having little or no free-lift.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for measuring parameters relating to the stability of joints in a patient's body includes the steps of securing a reference portion of the joint (that portion of the joint closest to the body) to a fixed location.  A three dimensional digitization of the size, shape, position and coordinate system of the two portions is performed.  A soft tissue compensation procedure is per-formed by applying forces to the reference portion of the joint to thereby determine the amount of reference portion motion, in the soft tissue surrounding the reference portion, due to these forces.  A variety of forces are applied to the relative portion of a joint, which is movable relative to the reference portion thereof, and the total motion of the reference and relative portions associated with the forces are measured.  By subtracting the motion determined in the soft tissue compensation from motion as determined by applying a variety of forces, the motion of only the relative portion relative to the reference portion is determined.

Abstract: PARALLEL CYLINDER INTERNAL COMBUSTION ENGINE          ABSTRACT OF THE DISCLOSURE          The  engine  disclosed  herein  comprises a number  of  pairs  of pistons, the two pistons in each pair acting in unison. The pairs are  arranged  parallel  to each  other,  and  the   pistons  are positioned parallel to and in a circle around the mainshaft which has  a cam lobe located at a convenient part of the mainshaft and encircling  the  mainshaft.  The cam lobe has  opposite  surfaces which  have  sinusoidal rises and dips  and are in  contact  with pairs of bearings attached to connecting rods.  The bearings  are on opposite sides of the cam lobe,  and at one time are driven in one  direction  by one of the two pistons in each pair  and   at another  time  in the opposite direction by the other  piston  in that pair,  the two pistons of that pair being connected to  each other  by  the  same connecting rod carrying the  bearings  which press  against the cam lobe.  The pressure exerted first  by  one bearing  and then by the opposite bearing in concert with similar thrusts  from  other  pairs of bearings  and  pistons,  causes  a steady, even rotation of the shaft on its linear axis. The action of  the  pistons  and  bearings is arranged  and  timed  so  that pressure against the surface of the cam lobe exerts vector forces against the curved surface of the cam lobe to effect rotation  of the main shaft. Centerline thrust of the bearings against the cam surface  and special desing of the cam surface to avoid  friction or  binding between the bearings and the cam are special features of  this engine.  The pistons may be driven by combustion  fuels, including  gasoline,  diesel,  etc.,  and may also be adapted  to steam operation.
