Abstract: This patent discloses thrust vectoring ignition chamber engine. Thrust vectoring ignition chamber used in this engine is an annular cylinder having nozzles mounted in a way such that during fuel suction phase they are sealed and during ignition of fuel they are unsealed so that hot jets of ignited fuel escaping through nozzles cause coupled rotatory motion on the ignition chamber. Engine uses cam operated suitably modified 3-screw compressor for suction and compression of fuel and therefore do not require piston mechanism. Flywheel mounted on extension of ignition chamber functions as output of the engine. Each half rotation of flywheel completes three phases namely fuel/air suction, compression and combustion. Thus this engine fires for every half revolution and therefore can give improved power boost.

Thrust vectoring ignition chamber used in this engine is an annular cylinder having nozzles mounted in a way such that during fuel suction phase they are sealed and during ignition of fuel they are unsealed so that hot jets of ignited fuel escaping through nozzles cause coupled rotatory motion on the ignition chamber. Engine uses cam operated two transverse piston based mechanism for suction and compression of fuel which facilitates separation of fuel valve from ignition chamber with the help of which combustion process and suction-compression process can occur simultaneously. Flywheel mounted on extension of ignition chamber functions as output of the engine. Each half rotation of flywheel completes three phases namely fuel/air suction, compression and combustion. Thus this engine fires for every half revolution and therefore can give improved power boost.

Abstract: This patent discloses unicycle with drive mechanism providing gear ratio, ergonomic seat tube and steering mechanism and reverse torque braking system. Drive mechanism comprises of a pair of drive assemblies mounted on the ends of the hub of the wheel. Each drive assembly consists of a special type of planetary gearbox in which plurality of planetary gears and a gear ring are arranged in such a way that gear ring can be rotated via pedal which in turn rotates planetary gears along its direction of rotation. Hub of the wheel at each end is coaxially connected to top planetary gear via one way ratchet ball bearing. Planetary gear on rotation rotates the wheel. Larger radius of the gear ring than hub planetary gear accounts for gear ratio. Drive mechanism doesn't come in contact with clothing of the rider. Reverse torque brake system provides protection against tipping off.

Abstract: This non-tilting steering system for reverse trikes uses three cross axis helical gear set. Steerer rod at the center, and steerer rod controlling the wheels are connected to cross axis helical gear set. Central gear set as well as gear set on the wheel consist of one vertical helical gear meshingly engaged, on its front and rear side, with two transversely oriented horizontal helical gears. Steerer rod at the center upon rotation via handle rotates coaxial worm gear which in turn rotates pinion helical gears engaged with it. Pinion helical gears at the center then rotates transverse helical gears of the gear set of the steering system at each of the wheels via a transmission shaft which in turn rotates the vertical helical gears attached to steerer rods of the wheels, thus rotating the wheels. This steering system can also be used in a four wheeler.

Abstract: This patent discloses a single bilateral rotary-steering-torque transmission arm based light weight steering system for four wheelers, which can be optimally configured to provide close approximation to Ackermann condition. Ackermann (anti-Ackermann) condition requires wheels to turn by unequal steer angles for inner and outer wheel. Therefore left hand side mechanism and right hand side mechanism turns the wheel asymmetrically and reverses their role while steering other side. This steering mechanism accomplishes bifurcation mechanism of steering action in to two different modes of steering at each of the two front wheels by employing special assembly of two sets of elliptic bevel gears. Monotonic increase in transmission ratio of conjugate pair of elliptic bevel gears with respect to meshing point with unity transmission ratio in appropriate region of elliptic bevel gears is utilized to achieve pro-Ackermann condition (or anti-Ackermann condition depending on the installation).

Abstract: This patent discloses bicycle steering lock system which can lock steering rod with the wheel oriented in desired angle. It is small in size, lightweight by design, durable, frame embedded and difficult to tamper with. It requires small modification in the steering rod of installing on it a coaxial crown gear and a rectangular hole on the head tube to mount lever and bolt.

Abstract: This patent discloses bilaterally mounted multi-axis multi-chain drive mechanism for bicycles facilitating application of driving force on larger area. It consists of pair of drive assemblies with each consisting of a special type of planetary gearbox in which plurality of suitably modified planetary gears and a gear ring are arranged in such a way that gear ring can be rotated via pedal which in turn rotates planetary gears along its direction of rotation. Each planetary gear at its center is attached to coaxially parallel chain crank which in turn meshes with a separate sprocket wheel mounted on rear wheel hub. Larger radius of the gear ring than planetary gears accounts for gear ratio. Drive mechanism doesn't come in contact with clothing of the rider. Seat stays are replaced by rear wheel support mechanism which facilitates better bicycle kinematics.

Abstract: This patent discloses non-tilting duplex wormface gear set based steering system for reverse trikes. Steerer rod at the center, and steerer rod controlling the wheels are connected to duplex wormface gear set each set consisting of one special worm gear two special face gear and three spur gears. Steerer rod at the center upon rotation via handle rotates coaxial worm gear which in turn rotates vertical pinion face gears engaged with it. Pinion face gear at the center then rotates transverse worm gear of the gear set of the steering system at each of the wheels via a transmission shaft which in turn rotates the horizontal pinion face gears attached to wheels, thus rotating the wheels. This steering system can also used in a four wheeler.

Abstract: This patent discloses three improvements in thrust vectoring ignition chamber engine described in my indian patent 201821027867 which uses multipurpose double action scotch yoke actuator. First is substituting bilaterally operated bipartitioned slot with quad-laterally operated (quad-partitioned) H-slot in scotch yoke actuator. Second is employing multiple slots instead of single slot in the scotch yoke actuator in conjunction with appropriate modification in the operation mechanism. Third is making arrangement in the scotch yoke operation mechanism which can allow mounting of crank farther from cam gear mounted on ignition chamber without increasing the size of cam follower gear. This patent discloses four models implementing above mentioned improvements. These improvements overcome drawbacks like sideward thrust, wear due to friction, etc. prevalent in conventional scotch yoke actuator.
