Abstract: A device enables a user to selectively change the flow of water produced by a waterspout between aerated flow and non-aerated flow. The device is preferably implemented as an adapter that is threaded to or otherwise coupled to the end of a waterspout such as a kitchen or bathroom faucet waterspout or a bathtub waterspout. The device includes a closure mechanism that is operable by a user to permit or prevent aeration of water flowing through the adapter. The adapter may include a control ring that may be rotated by a user to selectively open and close bores for introducing air into the interior of the adapter. When the control ring is turned to an open position, air is introduced and an aerated water flow is produced. When the ring is turned to a closed position, air is not introduced and non-aerated or laminar flow is produced. A user is thereby enabled to select the desired type of flow.

Abstract: A spray head for a faucet or the like has a wand body defining a flow path from an inlet to first and second outlets. Diverter seats are provided so a face seal on a diverter spool can direct flow to the first or second outlet. The spool is positioned by a trigger acting on cam surfaces formed on a toggle. A spring biases the toggle to one of two stable states. Movement of the spool by the trigger causes the toggle to change states so subsequent actuation of the trigger causes the spool to move in the opposite direction. The wand body also has a pause button that reciprocates in a chamber that is part of the flow path. The chamber includes a valve seat and the pause button has a spool having a face seal that is engageable with the valve seat to shut off flow through the spray head. A return spring causes separation of the pause button's face seal upon release of pressure on the pause button.

Abstract: A control to enable a further degree of enhancement in combustion efficiency in an automobile by effectively performing temperature control of cooling water in an automobile engine in accordance with various states of operation. Parameters from a variety of sensors that detect the state of an automobile engine are input into an engine control unit. Then, when the engine control unit determines from values of the accelerator opening and engine rotation speed, which serve as parameters indicating the operating state of the automobile, that the engine load is about to decrease, control is performed in the electronic control thermostat to maintain the cooling water temperature at a high temperature. Conversely, when it is determined that medium or high loads are due to increase, the control method is switched such that the electronic control thermostat is controlled by reading a target temperature corresponding to these parameter values from the engine control unit.

Abstract: Water faucets that allow the user to manually mix hot and cold water until the desired temperature is felt have existed for a very long time. However, it typically can take up to a few minutes of various manual adjustments to get the desired temperature. Since the early 80's there existed also the possibility of doing the mixing automatically until a certain preselected temperature is reached, for example by an electric faucet with a temperature sensor. However, these patents did not solve the problem of the waiting time until the cold water in the hot water pipe gets out, and they did not solve the problem of reaching the desired heat if the hot water source is not hot enough and/or reaching the desired coldness of the cold water source is not cold enough. Clearly a more sophisticated system is needed.
