The first flow assembly tube includes a tube having an inner chamber, including a flow sensor comprising a paddle wheel and a sensor and a temperature sensor for measuring discharge water temperature. The second temperature assembly tube plugs the inlet and the outlet of a heat transfer tube immediately adjacent to the flow assembly tube and includes a plurality of spring loaded temperature sensors in the plugged empty heat transfer tube.

Abstract: A method of hydraulic dredging employing apparatus and a procedure for subsidence dredging for subsurface removal of sandy strata which results in subsidence, or drop in elevation of the bottom deposits of a body of water, wherein sand is mined laterally beneath the surface by a combination jetting/siphoning device and is transported from the site of dredging by pipeline apparatus connected to pumping apparatus to an adjacent beach location; and wherein the procedure employs removal of hydraulic pressure which results in subsidence or sinking of the upper layer of marine deposits where the amount of subsidence is directly related to the subsurface quantity of material removed and the removed material is used for beach nourishment with minimal damage to shellfish or finfish inasmuch as the surface beneath the deposits are left intact.

Abstract: An improved sidelighting arrangement, device and method of controlling sidelight illumination of a motor vehicle during cornering employing two sets of side lamps, one for each side of the vehicle. The sidelighting arrangement apparatus includes a steering wheel angle sensor mounted on the column of the steering wheel for detecting a change in steering angle, a turn indicator sensor for detecting actuation of the turn indicator, a microprocessor for outputting an electrical signal to selectively illuminate a set of side lamps mounted on the side of the vehicle for controlling illumination of the sidelights during cornering of the motor vehicle responsive to the steering wheel in actuation of the turn signal for improved visibility for the operator of the vehicle and for improved safety of operation thereof by providing notice to other drivers of the cornering condition of the vehicle.

Abstract: A portable dispenser for a roll of sheet material comprising an enclosure of rectangular shape having a rear wall, bottom wall, having a free forward edge and a cover having a rear edge hingedly mounted to the rear wall being movable between an open position and a closed position for an open position for insertion of a roll of dispensing sheet material and a closed position for dispensing sheet material including a front cutting edge and including a compressible support for supporting the roll of sheet material by compressing when the full roll is inserted and gradually expanding when the material is utilized thereby raising the roll upward and frontward toward the dispensing area of the box, including the cutting edge, said compressible support being fixed to the interior of the box, whereby frictional resistance of the sponge also diminishes reverse rolling of the roll and the resultant pulling back of the leading edge of the sheet material wherein the cutting edge is held close to the parting segment of th

Abstract: A navigational plotter consisting of a triangular shaped navigational plotter, having two angle members and a rounded third corner employing a compass rose and a central orientation point for use as a navigation aid in combination with LORAN computerized navigational system or alternative Global Positioning Navigational Systems. This navigational plotter enables a navigator to easily locate the position of his ship on a chart by using input from the LORAN/GPS systems and by the use of this true course chart calculator which provides a course for checking the computerized course information and assists in avoiding obstacles in the path of travel not shown by the LORAN or GPS systems. When used with a LORAN or GPS system, the navigational plotter allows the navigator to plot a course on a chart or map and then to quickly locate the current position, orient the plotter correctly and get an overview of the true course.

Abstract: A shading device including an umbrella-like canopy comprising a collapsible frame and a flexible light-proof covering with a anchoring device for supporting the shade device above ground so that the canopy will serve as a sun shade, particularly for blocking the rays of the sun wherein the anchoring device including an offset support arm for overhanging the canopy and a anchoring helix adapted to be driven into the ground for providing support to the shading device, said anchoring device is mounted to the other end of a crankshaft with a hand crank for rotating the crankshaft in screw fashion to drive the anchoring helix to impart rotational force to drive the helical member of the anchoring device into the ground for anchoring.
