Abstract: A vehicle motion detector and control device arrangement includes a casing, a rotor rotated with the transmission line of the cable of the mileage meter of the motor vehicle in the casing, a rotary driven member revolvably supported on a damping oil in an annular end chamber of the rotary member and maintained in the middle position by magnetic expulsive force, and switch means mounted outside the casing and induced by a magnet at the rotary driven member to turn on a control device of the motor vehicle upon operation of the motor vehicle.

Abstract: A cloth take-up device for a circular knitting machine includes first and second vertical side panels, a cloth-transfer cylinder connected between the vertical side panels adjacent a top side of the vertical side panels, and two impression cylinders connected in parallel between the vertical side panels and peripherally disposed in contact with the cloth-transfer cylinder at two opposite sides for guiding a finished piece of knitted fabric over the cloth-transfer cylinder. Two parallel support arms are respectively pivoted to the vertical side panels. A cloth take-up cylinder is connected between the support arms. A transmission shaft is coupled to a main bevel gear by an auxiliary bevel gear. A gear train is coupled to the main bevel gear by another auxiliary bevel gear, and a belt transmission mechanism is mounted on the second vertical side panel.

Abstract: An automatic motorcycle stand including a gear box fastened to a motorcycle to hold a reduction gear set, a reversible DC motor controlled by a manual switch to turn the reduction gear set, a steering gear driven by the reduction gear set to turn a rocker shaft, a rocker arm driven by the rocker shaft to move the stand of the motorcycle between the operative position and the non-operative position, two limit switches alternatively triggered by an actuating screw on the rocker shaft to stop the reversible DC motor, a photoelectric sensor mounted in the speedometer of the motorcycle and triggered to cut off power supply from the reversible DC motor upon zero reading of the speedometer, a 2P manual switch switched to turn the reversible DC motor forwards or backwards alternatively, and a 2P limit switch mounted in the ignition switch of the motorcycle to lock the 2P manual switch from being operated to move the stand to the non-operative position when the ignition switch of the motorcycle is switched off, or to
