  • System for filling a baitwell in a fishing boat
    Patent number: 4832073
    Abstract: A distribution system for filling a baitwell in a boat includes a low pressure pump and a dual check valve. The fluid flow into the system is divided so that the pressure on the pump is reduced, thus enabling the use of an inexpensive pump. The check valve permits the influx of fresh water without the need for recirculating the existing water in the baitwell and also prevents backflow from the baitwell.

  • Fluid flow indicator
    Patent number: 4819577
    Abstract: An inexpensive fluid flow indicator capable of use in low flow conditions in a variety of environments, including but not limited to laboratory, industry, and medical applications. Flows are visually indicated by the rotation of balls loosely retained in a longitudinal passageway of the indicator's transparent housing by a flow guide and an outlet port. The flow guide imparts a circumferential or transverse direction to the axial flow of the fluid which causes the balls to revolve about the center line of the indicator.
