Abstract:
The device for detecting, assessing and signaling thawing of deep frozen foodstuff includes a stratified disc (1), which can be applied to the product to be checked, and formed by a first support (3), a second support (7) and impermeable transparent films (8, 9). A pattern (4), made on the first support (3) and extending up to a central display zone (6), is obtained by application of water expansion facilitating substances. Coloring water-soluble substances, which assume a well seen color when in contact with liquid water, are also applied to the display zone (6). The second support (7) has printed thereon information about the disc (1) use, and allows to see the display zone (6). The transparent and impermeable films, respectively upper (8) and lower (9), are fastened to the upper surface (3b) and to the lower surface (3a) of this first support (3).
Abstract:
This invention concerns a magnetic stand for cell phones of any type and make and may be used for example on a car dashboard thanks to the attracting force of the magnet on the metal parts in the phone battery.
Abstract:
A reactor is described for sterilising and drying urban refuse at 120-130°C. The new reactor is essentially characterised by a certain number of retractable blades disposed on a central rotating shaft and possibly also on its peripheral wall. The purpose of these blades is to turn over the mass in order to facilitate its sterilisation and drying. Discharge is facilitated to a maximum extent by retracting them when the operation is terminated.
Abstract:
Plant for treating urban refuse includes a cylindrical sterilisation and drying reactor with a central rotary shaft fitted with retractable blades. Retractable blades may also be disposed on the peripheral surface of the reactor. The blades turn over themass to facilitate and accelerate sterilisation and subsequent drying. On termination of the operation the blades are retracted so as not to obstruct the discharge of the mass. Drying is pref. carried out under vacuum in order to reduce treatment time.
