Abstract: A process for producing a multi-use cleansing agent basically harmless to human skin from d-Limonene, a natural citrus peel oil derivative. The d-Limonene extract, having the basic formula C10H16 is high in citric acid, carbon, and isopropyl compounds and exhibits similarities in organic structure to turpentine, dipentine compounds. The d-Limonene is mixed with a liquid detergent containing ionic and anionic surfactants in a ratio of two parts detergent to one part d-Limonene. To this mixture is added a fifty (50%) percent mixture of bicarbonate of soda and slaked lime solution in a ratio of three parts soda/lime solution to one part d-Limonene to serve as a buffer for the high acid content of the d-Limonene. Water is then added under pressure in a ratio of three parts water to one part of the total mixture to create turbulence and a complete mixing by surface aeration.

Abstract: A bilge pump switch apparatus for activating and deactivating the bilge pump of the vessel in response to predetermined water levels in the bilge area comprising a housing defining a chamber therein and provided with a fluid port for receiving and discharging bilge water, a mercury tilt switch suspended within the chamber and being responsive to tilting for opening and closing a circuit including a battery, the mercury tilt switch and the bilge pump, and a float responsive to the water level in the chamber for positioning the mercury tilt switch in its normally open position and its normally closed position.
