摘要:
A single point watering assembly for a monobloc battery having a plurality of cell access ports each have a top edge. The assembly includes a manifold and a plurality of valve cartridges. The manifold overlies the access ports and includes extensions each extending into one of the access ports. Each valve cartridge is supported by one of the manifold extensions and is located below the top edge of the respective access port. Consequently, the assembly presents a low profile extending above the battery.

Improved elastomeric valve seal members for use in a water distribution system between a water source and, for example, a baitwell or a livewell in a boat. The elastomeric seal members are made from material resistant to deterioration from engine exhaust gases, increasing overall reliability and longevity of the water distribution system.
摘要:
An improved aerator for oxygenating water and generating a circulating current within a livewell or baitwell while minimizing damaging turbulence. The aerator includes a downstream expansion area to reduce exit velocity, and an air intake conduit positioned to minimize stagnation of the liquid flow. The new aerator has an increased negative aspiration pressure, and can be operated at lower depths than previously possible.
摘要:
An automatic liquid dispensing apparatus including a container for holding a dispensable liquid, a flow regulator which permits liquid to flow out of the container at a controlled rate which is independent of the quantity of liquid within the container, and a timing and dispensing assembly. The timing and dispensing assembly accumulates a quantity of the liquid from the flow regulator, and periodically dispenses a constant volume of the liquid.
摘要:
A water distribution system for use between a water source and a livewell in a boat, capable of use with a boat in either moving or stationary states in the water source, and including means for operating the water distribution system in any one of three modes: a recirculate-only mode, a dual fill and recirculate mode, and a drain without refilling mode. Means are also provided, by utilization of an apparatus achieving tactile feedback, for apprising the operator of when the system is operating properly in a drip-tight, recirculation-only mode.

A pinch valve is provided for controlling the flow in a flexible wall tube. The valve includes a slotted saddle with female threading to receive a male threaded stem which is actuated within the saddle by a knob integrally connected to the stem. The slotted saddle may be installed onto an existing tube run without requiring disconnection. The stem has a spherical tip which contacts the tube to collapse to decrease the area flow therethrough. The knob and saddle are closely fitted to prevent spreading of the saddle during high thread loads. Calibration is also provided so that a desired flow control can be repeated with accuracy.
摘要:
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.
摘要:
A synthetic growing media, such as for a hydroponic growing system, includes a plastic body having multiple legs pointing in different directions. One or more of the legs has a bulbous tip. A synthetic growing medium comprising an aggregate of synthetic growing media and hydroponic system for plant cultivation are also disclosed.

The specification discloses a marine fluid connection system including a fitting and a connector. The fitting is cylindrical and includes a radially extending flange. The connector includes a cylindrical body, a plurality of levers on the body, and a locking ring on the body. The levers are movable between a latched position, in which the levers are closed on the flange to lock the connector on the fitting, and an unlatched position, in which the levers are open so that the connector may be removed from the fitting. The locking ring is axially movable with respect to the body to move the latches between their latched and unlatched positions.
摘要:
A battery vent cap capable of push-in installation and turn-out removal. The cap includes bayonet tabs. The tabs in turn each include a ramp portion to facilitate movement of the cap bayonet tabs past bayonet tabs in a battery vent port as the vent cap is inserted into the port axially without substantial rotation. The interfitting bayonet tabs retain the vent cap within the vent port and also permit the vent cap to be unscrewed and removed from the vent port. In a preferred embodiment, the vent cap includes a swivel connector to which a watering hose may be connected. The swivel enables the vent cap to be unscrewed from the vent portion without having to remove the watering hose from the swivel connector.
