Abstract: A wearable robotic exoskeleton system and method is provided to offer mobility to a user wherein the exoskeleton system implements at least a safety state and an operational state, and wherein when in the operational state, the user is enabled to control the gait implemented by the exoskeleton system by varying gripping pressure applied to external supports.

Abstract: A control valve which includes a main body, a stop valve, a spring-loaded control rod, a support rod and a corresponding shaft, a lid with a fixing element on it, a guide rod and a float cylinder. The float cylinder is restrained only to mover vertically on the guide rod. The stop valve moves vertically in a valve chamber on the upper end of the main body under the influence of water pressure. As water is flushed from the reservoir, the float descends along with the water level and causes the control rod to allow water flow from the upper part of the valve chamber, so that water can flow into the reservoir.

Abstract: A flow test stand system comprising a plurality of like test table units arranged in a head-to-tail manner to form an endless test-unit-chain to enable testing work to be carried out by only three operators in a minimum amount of time.

Abstract: A faucet valve comprising a removable cartridge which snaps into place, a taper-shaped insert that keys into a valve body and which fits tightly into a tapered annular ring. The lower portion of the cartridge has an external stop spanning over 90 degrees for stable stoppage of the faucet handle. The cartridge snaps together with the insert so that it can't fall out or become disengaged during assembly or normal usage. The insert has two straight projection keys which lock it into place on the valve body (i.e. prevent it from rotating on the valve body). The insert is tapered on its lower end so as to fit securely into a tapered annular ring. A locking cap secures the insert, and the pieces therein, in place vertically on the valve body.
