Normally hydroelectric dam powerhouses use river flow once before discharging it as turbulent tailwater, ineffective to spin turbines. The present invention uses tapered channels to confine and constrict turbulent tailwater into laminar flow that drives turbines both submersible and floatable utilizing the same water three times concurrently to generate new electricity. Channels originate adjacent to draft tube outlets, constrict in the downstream direction to create narrow necks where turbine / generators benefit from debris free, increased velocity and laminar flows to generate electricity. Hydroelectricity uses zero fuel, creates zero waste and has zero carbon dioxide emissions. Structures are uncomplicated, construction is within project boundaries minimizing environmental impacts and speeding projects coming online. New facilities are protected by existing dam security. Hydroelectricity replaces less dependable renewable energy systems.

The handhold of an exercise handgrip turns freely while seated between the open ends of the upwardly extending prongs. It can be easily removed by moving the specially formed end part of the handhold into an access opening wide enough to slip the end part through. In positioning the handhold's end part for this removal, it must be forcibly snapped through a narrow opening. By reversing the procedure, the handhold can easily be returned to its place of rotation. The specially formed end part of the handhold must, therefore, have a narrow neck-like portion to fit through the narrow opening but the end part must also be enlarged to keep it in place for rotation. Preferably, there is also a stem and ball unit in one of the prongs which swings into place to trap exercise sheeting, cord or other media within an opening at the handgrip's bottom portion.

A housing for a thin active probe has two identical molded housing-halves that when assembled form a cavity that encloses the chassis upon which is carried the active circuitry of the probe. The parts exhibit complementary self-symmetry about a longitudinal axis, such that when one is rotated about that axis it performs the mating functions needed to interlock with another part representing its un-rotated self. Interlocking is accomplished by circular tabs and sockets that interfere and prevent the parts from separating once the tabs are in the sockets. The circular tabs are joined to the balance of the housing-half that carries them by a narrow neck and can be sprung over the other housing-half to return to their natural position and fit into a circular socket in that other housing-half. A tapered edge or ramp portion on the underside of each circular tab allows it to automatically spring out of the way as the two parts are moved toward each other in a direction generally perpendicular to the longitudinal axis of the parts. Each circular socket contains a stop that prevent its tab from completely passing through the socket. Each housing-half has a straight tab between its circular tabs that enter an interior recess on the other housing-half to support its circular sockets as they receive their tabs. Each housing-half contains in a front surface an entire aperture for a detachable probe lead, and each contains in a rear surface at least one half-aperture that, when the two housing-halves are joined, forms a larger aperture whose perimeter engages a corresponding groove in a strain relief for a cable. The exterior surface of the mated housing-halves has, on each side through which runs the line of the mating edges, a flat shallow recess. The interlocking circular tabs and sockets are located within the extent of this shallow recess, which can receive an adhesive label that may conceal and stiffen the interlocking circular tabs and sockets.

A seal for a regenerative air preheater. The seal is comprised of two members that each have a plurality of tabs and slots. The tabs and slots interlock so that the tabs on one member are positioned adjacent the slots on the other member. The tabs have a narrow neck section and a wider sealing section. The wider sealing sections overlay and the narrow neck sections are positioned within a recessed region of the notch on the opposite member so as to interlock the two members. The seal is mounted either to the rotor or to the inner wall of the housing so as to extend through the bypass gap between the rotor and the inner wall of the housing. As the tabs are flexible, the tabs may resiliently deform as a result of the tabs making contact with the sealing surface of the heat exchanger. The air preheater further comprises a reinforcing section that stabilizes the tabs when the tabs resiliently deform.
