The invention is a rod to rod connector that can be used to interconnect two generally parallel spinal rods of a spinal rod and anchor system. The connector comprises a transverse rod and two pairs of clamping bodies, one for each spinal rod. Each pair connects one of the longitudinal spinal rods to the transverse rod in infinitely adjustable angular relationship. One of the two clamping bodies of each pair comprises a C-shaped channel for accepting the spinal rod. The channel is in communication with a slot that defines a hinge. A threaded screw hole passes transversely through the slot and permits a screw to squeeze the hinge, thereby causing the C-shaped channel to close around and clamp the rod. The second clamping body is similar to the first except that there is no slot or hinge and the screw hole preferably is not threaded, but includes a countersink for seating a chamfered screw head. Also, an angular portion of the screw hole intersects the C-shaped channel. The two clamping bodies are aligned with each other so that their screw holes are coaxial so that a single screw can pass through both holes thereby clamping both rods in the C-shaped channels and fixing the angle between the two clamping bodies and, hence, the two rods. The first clamp clamps the spinal rod by squeezing the hinge to cause the C-shaped channel to squeeze around the rod. The second clamp clamps the transverse rod by virtue of the bottom of the screw head bearing down on the transverse rod over the portion of the screw hole that intersects the C-shaped channel.

A fluid tank valve assembly of the type employed for water tanks for toilets has a tank refill valve located atop a fluid inlet supply tube. The refill valve has a lever that is raised and lowered to open and close the valve. An inverted, cup-shaped hood is positioned atop the valve and a float is located about the skirt of the hood and secured thereto by the force of friction. The float can be moved longitudinally along the skirt of the hood in order to vary the water level at which the hood bears down upon the lever arm or is lifted from the lever arm, thereby varying the water level at which the valve is actuated. The valve itself is equipped with a metering pin that is configured to reduce the likelihood of clogging in the longitudinal passage of the core of the valve diaphragm. A unique coupling between the water inlet supply tube and the hollow mount at the bottom of the tank prevents complete separation of the water inlet supply tube relative to the mount, but permits longitudinal adjustment therebetween so as to vary the height at which the refill valve is mounted within the tank.
