Abstract: A system for coupling a conduit to a valve is disclosed. The valve includes at least one coupling, wherein the coupling includes an inlet leading to an internal chamber of the valve, a collar positioned within the inlet, a gripper positioned partially within the inlet and in contact with at least a portion of the collar, and a wiper seal positioned within the internal chamber. The system further includes a conduit, wherein the conduit is insertable through the gripper via a first force, and wherein the conduit is subsequently insertable through the wiper seal via a second force that is less than the value of the first force. The conduit may optionally be labeled with a set of visual markings to provide proper cutting angles and to indication proper positioning of the conduit into the valve to effectuate a tight seal.

Abstract: A float actuated valve assembly for battery electrolyte replenishment is disclosed. A housing engages an opening in a battery cell. An inlet in the housing is connectable to a water source. A valve in the housing controls the water flow to the cell. The valve is connected by a link to a four bar mechanism that is attached to a float. The float is buoyantly supported and rises and falls in response to the electrolyte level within the cell opening and closing the valve to admit or halt the flow of water to the cell. A baffle prevents fouling of the mechanism by splashing electrolyte. A flash arrester is positioned between the valve and the inlet to quench hydrogen-oxygen explosions between cells. The float is adjustable for different sized cells. A side viewable electrolyte level indicator is provided in the housing. Flash arresters for venting gas are also mounted.

Abstract: A trampoline system is described. The trampoline includes a frame, a jumping mat and elastic means for connecting the jumping mat to the frame. The jumping mat includes a substantially horizontal jumping region between two arcuated shaped jumping regions at opposing ends of the horizontal jumping region when connected to the frame. The frame may include two opposing ends formed from a pair of substantially parallel arcuated tubes each having a substantially vertical end, a substantially horizontal end, and a mid-point along its curved length, a support bar connecting the arcuated tubes at their substantially vertical ends, a pair of end footings, wherein each end footing is connect to the support bar and to the mid-point of one of the arcuated tubes, and a pair of side footings, wherein each side footing is connected to a leg of one of the end footings and to one of the arcuated tubes at its substantially horizontal end.

Abstract: An automatic shut-off valve suitable for watering of batteries is disclosed. The valve is formed by a chamber having an inlet and an outlet. A seat surrounds the outlet. A spring biased piston within the cylinder is movable into and out of sealing engagement with the seat to open and close the valve. A flow deflecting surface is positioned between the inlet and the piston. Water flow is directed around the piston to eliminate drag that would force the piston into engagement with the seat. A second deflector surface directs flow against the piston to bias it open. An actuator cup, fed by a nozzle extending from the outlet, draws the piston into engagement with the seat when the cup is sealed by engagement with the electrolyte surface. The valve may also employ a float actuator connected to the piston.

Abstract: A quick connect coupling for a battery watering system is disclosed. The coupling has a housing with inlets and outlets, each having a collar with a tapered bore. A collet having flexible fingers attached to a ring is axially movable within the collar. The fingers have inwardly pointing teeth positioned distally to the ring. The collet receives a conduit coaxially. The teeth engage the outer surface of a conduit when it is inserted into the housing through the collet. The teeth grip the conduit and are forced into engagement with it by engagement of the fingers with the tapered bore of the collar when force is applied to withdraw the conduit from the housing. The teeth are preferably made of plastic.

Abstract: A method and device for filling a container with liquid up to a predetermined level. The device includes a cylinder and a piston movable within the cylinder between a rest position and a fill position. A supply of liquid for filling the container is provided to a first end of the piston at alternating pressures to cycle the piston back and forth between the rest and fill positions. Each time the piston reaches its fill position, supply liquid is added to the container. With each cycle the device draws fluid from the container and then attempts to compress the drawn fluid with a second end of the piston. When the fluid drawn is gas, the piston can compress the gas to continue moving to the fill position. When the drawn fluid is liquid, the piston can not compress the liquid and thus is stopped to prevent further filling.
