Abstract:
An engine (10) which can deliver mechanical work for an extended duration in comparison to the duration of energy input into the engine. The engine (10) includes a drive shaft (11) through which it delivers mechanical work. The drive shaft (11) is drivingly connected to an electrodynamic machine (13) for generating electrical energy. The drive shaft (11) is driven by a drive system (15) which incorporates various drive mechanisms (16), power means (17) for operating the drive mechanisms (16) and gearing (18) for drivingly connecting the drive mechanisms (16) to the drive shaft (11). The various drive mechanisms (16) are operated in a pre-determined sequence by the power means (17). Each drive mechanism (16) is in the form of a rack and pinion mechanism. The power means (17) for operating the drive mechanisms (16) comprises spring structure associated with each rack of the rack and pinion mechanisms. The power means (17) also comprises a hydraulic ram for loading each of the spring structures.
Abstract:
An internal combustion engine includes a slide body having a plurality of rigidly mounted pistons on opposite ends of the slide body. The slide body reciprocates and is connected to a flywheel by shaft and bearing which extends through an angled track in the slide body. As the pistons impart linear movement to the slide body, the flywheel and a drive shaft rotate. Both the slide body and the flywheel are mounted on the interior of the engine. Magnets on the flywheel rotate relative to stationary coil conductors to induce a current. The housing includes four panels, which can be easily assembled and disassembled, which form a housing compartment in which the linearly movable slide piston subassembly and the rotating flywheel are positioned.
Abstract:
A hydraulic actuating mechanism, comprising a casing (1) which contains a piston (3) with a tractive guiding element (7) passing through it and a means for alternate coupling of the piston (3) with the element (7). A cable serving as the tractive element (7) is passing hermetically through the butt-ends (2, 2') of the casing and the piston (3) in which a means (8) for coupling with the cable is mounted and so arranged as to couple with and uncouple from the cable when a fluid medium is fed under pressure to one of the chambers of the casing (1).
Abstract:
A shape memory alloy step drive mechanism comprising at least one shape memory alloy element (1) with a fixed end and the other end being connected to one end of a lever (2). The lever (2) is provided with a pawl (4) which is located to move on the teeth of a ratchet wheel (5) mounted on a main shaft (6) along with the lever (2). A stopper pin (7) is provided which also guides the pawl (4) on the ratchet wheel (5). A bias spring (9) is provided on a mandril on the main shaft (6) for returning the lever (2) to its original position. A detent wheel (8) with at least one detent lever (10) is mounted on the main shaft (6) to provide the detent torque required to hold the main shaft (6) in position when the lever (2) returns to its original position. A pair of support brackets (11) are provided for supporting and holding the said components together in an assembly.
Abstract:
A driving mechanism transforms continuous longitudinal reciprocation of a piston (3) in a chamber (2) into unidirectional rotation. The mechanism utilizes a closed wave-shaped groove (8) defined in either the cylinder (1) or chamber (2) and adapted to receive guiding members (9) projecting from the other of the piston (3) and chamnber (2). When the piston (3) is forced to move longitudinally in either direction, the groove (8) slides over the guiding members to force rotation. The apices (13) of the wave-shaped groove (8) are either contoured or provided with a gating structure (21) to assure that the guide members do not backtrack but instead move in one direction through the groove (8).
Abstract:
The stepping drive mechanism comprises a toothed wheel (5) and an operating member which advances the toothed wheel each time by one tooth, the plane wherein said member moves being perpendicular to the plane of the toothed wheel (5). The operating member is a twin arm pawl (3) which is mounted pivoting on a slide (1) which has a reciprocating motion, the pawl presenting a tooth guiding surface (4) which is inclined with respect to the displacement direction of the slide (1) and which passes from one inclined position to the other upon each switching cycle.
Abstract:
An internal combustion engine includes a slide body (50) having a plurality of rigidly mounted pistons (56A-D) on opposite ends of the slide body. The slide body reciprocates and is connected to a flywheel (70) by shaft (74) and bearing which extends through an angled track in the slide body. As the pistons impart linear movement to the slide body, the flywheel and a drive shaft rotate. Both the slide body and the flywheel are mounted on the interior of the engine. Magnets on the flywheel rotate relative to stationary coil conductors to induce a current. The housing includes four panels, which can be easily assembled and disassembled, which form a housing compartment (10) in which the linearly movable slide piston subassembly and the rotating flywheel are positioned.
Abstract:
An apparatus (10) for rotating a drum (12) employs a plurality of drive sprockets (20) disposed about the outside surface (14) of the drum (12) and spaced-apart along the length of the drum (12). Each drive sprocket (20) has a first flange (22a), a second flange (22b) and a plurality of pins (24) interconnecting the first flange (22a) and the second flange (22b), spaced-apart about the drum (12) and parallel to the axis (16) of the drum (12). Spaced-apart hydraulic rams (30) each exert a force on one of the drive sprockets (20) so as to cause rotation of the drum (12). Each ram (30) is movable between a linearly retracted first state (A) and a linearly extended second state (A') and has a first end (34) and an opposite second end (32). The first end (34) is secured to the base (18), the second end is engageable with the pins (24) of a selected drive sprocket (20) so that as the ram extends from the first state (A) to the second state (A'), the ram exerts force on a pin (24) in the first direction (B), the first direction (B) being tangential to the outside surface (14) and perpendicular to the axis (16) of the drum (12). Force from the rams (30) is transferred to the drum (12) through the pins (24), the first flange (22a) and the second flange (22b). A plurality of spaced-apart ratchet stops (40) prevent movement of the drum (12) in a direction opposite the first direction (B). Torque applied to the drum (12) by the rams (30) is distributed along the length of the drum (12) at each of the plurality of drive sprockets (20).
