Abstract: The present invention provides a template book to assist an individual in drawing images or shapes on a drawing surface more accurately than if the individual were to attempt to draw the same images or shapes by freehand. A number of template pages are provided in the form of a template book wherein each template page includes a plurality of foldably attached template sheets which form a drawing template when folded out over a drawing surface.

Abstract: The present invention provides a high-efficiency water pump and heater assembly for use with a pool or spa as a device that facilitates the filtering and heating of the pool water. A water pump and turbine engine are combined using an inventive linkage assembly that incorporates a revolutions per minute (rpm) reducing device. The rpm reducing device is operative to reduce the rpm speed associated with the turbine engine substantially to a revolutions-per-minute speed commonly associated with pool water pumps. A heat exchanger is disposed in the exhaust path of the turbine engine whereby water flowing through the heat exchanger coils is heated to a predetermined threshold as monitored by a temperature-monitoring device. The temperature-monitoring device causes a bypass device to redirect the flow of exhaust air once the predetermined temperature threshold has been reached such that the heat exchanger coils are bypassed as long as the water temperature is at or above the predetermined threshold.
