Abstract: An electrical force and/or deformation sensor includes a support structure constituted by a rigid plate in one face of which a recess is formed. The bottom wall of the recess is thin and is resiliently deformable under the action of a force or pressure to be measured. At least one piezoresistive sensitive element constituted by a thick-film resistor is applied to the other face of the plate in correspondence with the recess. Electrical conductor elements connected to the sensitive element or elements are also applied to this face of the plate to enable its connection to supply and processing circuits.

Abstract: A large compressor has a four throw crankshaft, four connecting rods, four crossheads, and four horizontally opposed pistons. As usual, each piston is offset from its opposing piston and this causes the usual inertia force couples (primary couples and secondary couples). The crankshaft has counterweights thereon. A parallel oppositely rotating countershaft has balance weights thereon. These rotating weights balance the two primary inertia force couples. The crank sequence and the crosshead/piston locations are such that the two secondary inertia force couples counteract each other and no other secondary balancing device is needed. Further, the same counterweights also serve to balance the four crankpins and the large ends of the four connecting rods. Thus, the whole machine has near perfect balance with no unbalanced reciprocating primaries, reciprocating secondaries, primary couples, secondary couples, or rotating unbalance.

The crank disc meshes with a pinion of a driven shaft. By this development the characteristics of the crank drive can be chosen within a wide range. Combustion and efficiency can be increased upon employment in a piston combustion motor.
