    摘要: A roller-band device including an idler roller, drive roller and band, is mounted on a carriage movable linearly relative to the band so that the angle of rotation of the drive roller is related to the distance traveled by the carriage. The drive roller can be driven to convert rotary motion to linear motion or the carriage can be driven to convert linear motion to rotary motion. Means including a pulse generator coupled to the drive roller produces a very accurate readout of the position of the carriage.

    摘要: The invention is a new vent cap for a liquid acid electrolyte storage cell. The vent cap comprises a diaphragm or membrane that is permeable to oxygen and hydrogen gas and substantially impermeable to the liquid electrolyte. Means are provided for fixedly securing the diaphragm in the vent cap assembly.

    摘要: A buckle comprising a frame member formed with strap openings at its ends and a bridge intermediate its ends; and a clamping member pivotally mounted intermediate its ends to the frame member. The clamping member has a tongue at one end extending beneath the bridge for clamping a strap against the bridge and a strap slot near its other end bounded on one side by an edge overlying a strap opening in the frame. This slot edge is further from the pivot axis than the bridge so that a pivotal force applied to the clamping member at the edge by tension on the strap is multiplied to clamp the strap between the tongue and bridge. A spring is mounted on the frame for biasing the tongue toward the bridge and a lanyard is attached to the clamping member for pivoting it to release the strap.
