Abstract: System of unmanned underwater vehicles with multiple variable-geometry internally pressurized flexible hulls (that enable the underwater vehicle to submerge/emerge and change submersion depth by varying hull's buoyancy and not the vehicle weight) and possibly at least one pressure hull housing e.g. accumulators and electronic steering system. Each flexible hull is composed of a number of flexible hull segments modules.

Abstract: Continuously variable hydro-mechanical transmission includes an input shaft and an output shaft, a torque converter and an eccentric gear set including at least one main gear, a planet gear, a main eccentric and an auxiliary eccentric of adaptable eccentricity, wherein the input shaft is connected to the turbine rotor and one member of the eccentric gear set, the pump rotor is connected to another member of the eccentric gear set, and the output shaft is connected to yet another member of the eccentric gear set. This arrangement introduces strong positive feedback between the pump rotor and the turbine rotor, which results in large maximum torque ratio and large rate of growth of torque ratio, as well as large ratio spread, which can be adapted by changing eccentricity of the auxiliary eccentric.

Abstract: Split power hydro-mechanical transmission includes an input shaft and an output shaft, a torque converter and a planetary gear set, wherein the input shaft is connected to the turbine rotor and the ring gear or the sun gear, the pump rotor is connected to the sun gear or the ring gear, and the output shaft is connected to the planet carrier. This arrangement introduces strong positive feedback between the pump rotor and the turbine rotor, which results in large maximum torque ratio and large rate of growth of torque ratio, as well as large range of (naturally automatic) torque ratio variation.

Abstract: A sliding friction-free gear has cams of specific profiles, rollers separating cooperating cams that roll over the cams of the gears, thus eliminating the sliding friction between the gears. The rollers are mounted rotatably e.g. in sliders or eccentrics, wherein the sliders, resp. eccentrics, are mounted slidingly, resp. rotatably, in a yoke attached rigidly to a shaft. The rollers are free to execute oscillating motion relative the yoke while rolling over the cam profiles of the cams of the gears. The cooperating members of the gear contact along a line like in conventional evolvent gears, and unlike in the Wildhaber-Novikov's gear (where the momentary contact between teeth of cooperating toothed wheels is pointwise); therefore the gear according to the present invention offers much larger transmission capacity and is much less prone to seizure than known gears.

Abstract: Rotary positive displacement internal combustion two stroke engine with only one major moving part, i.e. engine's eccentric shaft, with cylinders encompassing eccentrics of the shaft, with said eccentrics being suitably sealed in said cylinders, wherein combustion gases exert force directly on said eccentrics of said eccentric shaft. Gas forces can be nullified by suitably phasing shaft's eccentrics, thus nullifying gas forces loading shaft's bearings. The engine is naturally perfectly balanced. The engine possesses natural self-cleaning capability, and is capable of being fueled by coal dust. Units of the type developing 2 000 MW and 3 000-3 6000 rev/min, intended to replace steam turbines in power stations, can be built.

Abstract: A positive displacement internal combustion engine with the strongest mechanism for converting thermal energy of combustion gases to rotational motion, being composed of a body with spherical combustion chamber, and three spatial eccentrics being placed in said spherical chamber. The mechanism is particularly suitable for heavily loaded detonation and homogeneous charge compression ignition engines.

A fluid handling system therefore, method and apparatus are also disclosed.

Abstract: The invention relates to heat engines and more specifically to positive displacement internal combustion engines, and is particularly concerned with oscillating engines i.e. engines, in which piston executes oscillating motion. The invention provides the optimal, “canonical” form for the two stroke oscillating engine of unique strenght and compactness.

Abstract: The invention provides the proper form for the rotary positive displacement internal combustion engine. The construction of the engines according to the invention is based on a specific form of four bar mechanism and features unique simplicity (only three moving parts, no valves or camshafts, no gears to transfer piston movement to rotary movement), compactness and strength that make the engines according to the invention similar in these and some other aspects (e.g. power density) to gas turbines.

Abstract: The invention solves the problem of designing and manufacturing springs made of elastic materials, particularly steel springs, with prescribed characteristic (dependence of flex on external load) given by a smooth (i.e. differentiable) non-linear function. The method according to the invention consists in forming an elastic body with suitably shaped regions of diversified stiffness and (possibly) diversified initial internal stresses (this suitable shape of the regions lies at the hart of the invention and is covered by separate patent claims).
