Abstract: The invention concerns a water-saving mixer tap with a first water inlet, a second inlet for thermally conditioned water, such as a hot water inlet, at least one service water outlet for water coming from the first water inlet, from the second water inlet or from both, and remarkable in that it further comprises an auxiliary water outlet, and means for interconnection between the conditioned water inlet and the auxiliary outlet with a view to preparing conditioned water without losing water via the service outlet. The invention also concerns a flowing water system comprising such a mixer tap. The auxiliary outlet of the tap is connected to an auxiliary pipe provided with means for storing and/or means for discharging the water from the pipe for water which has lost the conditioning of same and flows towards the auxiliary pipe when the tap is in the position for preparing conditioned water.

Abstract: The invention relates to a mixing water faucet, comprising a hot water inlet, a cold water inlet, and a service water outlet. The faucet also comprises a service flow adjustment valve which comprises an interconnection position enabling at least one first passage between the hot water inlet and the cold water inlet to be opened.

Abstract: Device for a subject which is moving over the land is adapted to provide a mounting for a map of the immediate vicinity and having input signal means representing distance travelled and signal means representing changes of direction of travel, and responsive means which will move an object over the surface of the map to continuously represent the position of the subject with relation thereto.

Abstract: The invention is concerned with an improvement in a valve system comprising a fluid operated main control valve and adjustable servo valve means for controlling the main valve, the main valve including a main valve spool reciprocal therewithin and a first and a second main valve chamber, one adjacent each end of the main valve spool. The improvement of the invention comprises an adjusting means operating via fluid displacement. Briefly, the improvement comprises means for moving the main valve spool responsive to a first fluid being flowed in to a first main valve chamber at a first end of the spool and at the same time being flowed out of a second main valve chamber at a second end of the spool. Also part of the improvement are servo valve means operating on pressure from a pressurized pilot fluid source for controlling the first fluid flow to and from the first and second main valve chambers.
