摘要： The present invention discloses a method of preparing an electrode material for lithium-ion batteries comprising the steps of preparing a mixture of precursors taken in predefined stoichiometric ratios for synthesis of lithium iron phosphate (LiFePO4), adding niobium pentoxide as a precursor for doping of niobium at Li+ site of LiFePO4 for synthesis of niobium doped LiFePO4 and ball milling operation provides nano sized powder particles. Now, a precursor of carbon is added to said mixture of precursors for synthesizing and obtaining carbon coated niobium doped LiFePO4 nano sized powder particles. Pellets of required size are prepared and sintered. The obtained pellets are structurally characterized.

摘要： An automated projectile loader and a method of loading projectile for a vehicle is disclosed. The automated projectile loader includes a carousal projectile unit mounted on a hull of the vehicle. The carousal projectile unit includes a carousal storage adapted to store a plurality of projectiles oriented in a vertical direction. The automated projectile loader includes a bustle projectile unit disposed at a rear end of a turret of the vehicle. The bustle projectile unit includes a bustle storage adapted to store a plurality of projectiles and propellants oriented in a horizontal direction. The automated projectile loader includes an automated arm disposed below the turret and adapted to load the plurality of projectiles from one of the carousal storage and the bustle storage in a barrel orientated in any angle in the turret.

摘要： A full-body protection gear is disclosed. The protection gear includes a torso protector, an arm protector, and a lower body protector. The torso protector includes a protective vest defining a neck opening, a first arm opening, and a second arm opening. The torso protector includes a front shield, aback shield, a first pair of side shields, a second pair of side shields, a first shoulder shield and a second shoulder shield fixedly disposed on the protective vest. The arm protector includes a first part adapted to cover an upper arm region of a user extending from a shoulder to an elbow, and a second part adapted to be removably coupled with the first part and to cover a lower arm region of the user extending from the elbow to a palm. The lower body protector includes a first part adapted to cover pelvic region and an upper leg region of a user, and a second part removably coupled with the first part in a partial overlapping manner, and adapted to cover lower leg region of the user. The lower leg region is indicative of a region extending from above a knee joint to above an ankle joint of the user.
