Abstract: A valve or nozzle device for atomizing a liquid into very small drops comprises a valve member (21) having an annular surface part (24) diverging in a direction downstream of the valve seat (32). The valve member is reciprocatingly moveable between open and closed positions. The valve member (21) is opened very rapidly by an impact member (38) driven by magnetic forces generated by a solenoid (41). The vibrating frequency is controlled by an electric control circuit so as to obtain the desired small droplets and the desired dosage. The atomizing nozzle may, for example, be used to atomize a liquid medicament or to atomize liquid fuel.

Abstract: An atomizing nozzle device comprises a housing in which an inner chamber is defined. Fluid is introduced into the chamber and is discharged therefrom through an orifice of a metallic screw cap of the device. Within the chamber a stem is arranged, which stem is connected to a closing head cooperating with the orifice through a rod. A spring acts on the stem for causing the head to close the orifice and consequently prevent the discharge of fluid from the device. A solenoid coil is provided and supplied with a current through a current path in which a switch contact is established through the cooperating closing head and the end cap. By the supply of an energizing current to the solenoid coil, the stem is caused to move causing the closing head to move relative to the orifice for opening the orifice and consequently discharging fluid from the nozzle device.

Abstract: A disposable maximum reading thermometer comprises a body (40) in which a capillary passage is defined, a reservoir (41) communicating with the passage and a heat expansible indicator medium (46) contained in the reservoir. The reservoir and the passage are adapted to allow expansion of the medium in the passage when the medium is subjected to heating. At least a part of the passage wall exposable to the indicator medium is adapted to undergo a detectable and irreversible change of its light penetration characteristics when brought into contact with the medium. The capillary passage is defined by a rod (48) arranged in a longitudinally extending bore (42) of the body (40). The surface of the rod is frosted (matt) or opalized, preferably by a mechanical treatment, and adapted to be deopalized when brought into contact with the medium.
