Abstract: System for the recovery of washing liquids used in showers, wash basins, and/or baths, including a first decantation tank provided with at least one inlet connected to a downflow point of washing water, a second collection tank, an overflow partition wall adapted to separate the two tanks, a sewer drainage at the bottom of the decantation tank, adapted to be closed by a plug that can be raised by a float in the collection tank according to the liquid level therein, a drawing pump in the collection tank, controllable by a relay, or electrical float, indicating the liquid requirements of a fixture, a pipe connecting the pump of the collection tank with the fixture, the relay, or electric float, electrically connected with the pump and a valve of the fixture and controlled by a float in the collection tank for closing the electrical power supply to the pump and opening the electrical power supply of a valve for liquid flow to the fitting.

Abstract: System for the recovery of washing liquids used in showers, wash basins, and/or baths, characterised in that it includes a first decantation tank (1) provided with at least one inlet (100) connected to a downflow point of washing water, a second collection tank (2), an overflow partition wall (3) adapted to separate the two tanks (1, 2), a sewer drainage (101) at the bottom of the decantation tank (1), adapted to be closed by a plug (5) that can be raised by a float (4) in the collection tank (2) according to the liquid level therein, a drawing pump (7) in the collection tank (2), controllable by a relay (6), or electrical float, indicating the liquid requirements of a fitting (103), a pipe (104) connecting the pump (7) of the collection tank with the fitting (103), the relay (6), or electric float, electrically connected with the pump (7) and a valve (8) of the fitting (103) and controlled by a float (9) in the collection tank (2) for closing the electrical power supply to the pump (7) and opening the electr

Abstract: It is described a process and an apparatus in which the cure of the concrete is accelerated by raising the temperature and moisture values in the environment in which the cure is taking place. The process comprises the following steps: making up at least a test piece obtained through the casting of a predetermined amount of concrete to be tested into a hollow mold; introducing the made up test piece into a vessel; adjusting the chemico-physical parameters of the environment in the vessel, following predetermined operating steps; operating a device adapted to measure the compression strength of the test piece, which brings about the generation of signals depending upon the measured compression strength; processing and displaying the signals.
