Title: Harmonic reciprocating heat engines
Inventor: PATTAKOS EMMANOUEL
IPC: F02B75/02
Filed: 1991-04-02
Abstract: 2083592 9217694 PCTABScor01 Main characteristics of the suggested type of engines are the harmonic reciprocation of the pistons and the slider free motion of the relevant connecting rods. The invention also pertains to the full balancing of such engines, to the scavenging of two-stroke internal combustion harmonic engines, to the sealing or isolating between crankcase and cylinder walls of harmonic engines (independent lubrication in the crankcase and on the cylinder wall) and special architectures for carrying out the suggested engines. This invention faces the problems of the heat engines by acting separately on the thermodynamical function using a different time-function of the volume of the working medium during the cycle and on the mechanical function introducing mechanisms of lower inertia, lower friction and of full balance. In general, the harmonic engines are similar to the conventional engines as regards the "upper" part (that is: cylinder head, piston head and rings, cylinders, intake and exhaust systems, ignition system etc). The difference is in the kinematic mechanism, that is the components and the way they cooperate to change the reciprocating motion of the pistons into a rotary motion of the shaft. The use of the invention: at least where a conventional reciprocating heat engine is used.

Abstract: STORAGE BATTERY AND METHOD OF CONNECTING CASE SEALED TERMINALS TO INTERNAL ELECTRODE PLATES                 Abstract of the Disclosure In this invention, lead based battery terminal units are molded in a fluid tight manner into the main body of a polypropylene battery case so that only the outer ends of the terminal units are external to the case.  The terminal units have elongated straps internal of the case slotted to receive the projecting lugs integral with positive and negative lead based electrode plates, which are interleaved with one another and with glass mat separators.  After the plates and separators are installed in the main case, and with the extending electrode plate lugs appropriately fitted in the slots of the straps, flux and glass beads are inserted in the void areas in a strap-lug amalgamation zone.  This zone is accordingly cleaned by the flux while the lugs are laterally supported with respect to one another by the glass beads.  The case is subsequently closed by a polypropylene cover plate which is heat sealed thereto to form a substantially water tight assembly, but having  amalgamation gas escape vent holes strategically located therein.  The closed case is partially inserted in a tank containing a level of circulating cooling water supplied thereto without water leakage into the sealed case.  With the polypropylene case being cooled by the circulated water to prevent heat damage thereto, a low voltage magnetic induction welding head assembly mounted within the tank can be electrically energized to provide a high frequency welding field that heats the strap and the lugs in a burn zone so that the lugs and strap metals fuse together.  The battery is subsequently completed by the addition of electrolyte through the vent holes to saturate the mats and these vent holes are then sealed.
