Abstract: The invention concerns a spacecraft propellant tank designed for storing and supplying fuel to the propulsion system, as well as its application method, which is related to space technology and particularly to the design of tanks for storing liquid propellants within rocket engines. The tank in question comprises a body featuring at least one convex edge that creates a corner capillary and an intake port positioned on one of these convex edges. Additionally, the tank's interior surface is treated to be hydrophilic. The objective of this invention is to develop a spacecraft propellant tank characterized by its lightweight and straightforward design. It facilitates the creation of various propellant tank shapes while minimizing the quantity of internal components that reduce useful volume. It also ensures consistent and reliable functionality of the propellant system with continuous supply of propellant to the intake port, even in the absence of gravity and during multiple activations of the propulsion system.

Abstract: An electrothermal subassembly of a steam thruster for nanosatellites. The subassembly has an inlet port for the supply of the working mass, heat exchangers with containing ducts, at least one heating element, a supersonic micro-nozzle, and a plurality of rods forming a truss structure.

Abstract: A weighing device for a multi-head weighing machine and comprising a load cell configured to generate a first signal representative of the weight force exerted by a bucket, and at least one accelerometer configured to generate a second signal representative of the vibrations induced on the bucket at least during a use configuration of the multi-head weighing machine. Furthermore, the weighing device comprises a control unit configured to compare and process the first signal and the second signal and to generate a rectified signal representative of the weight of at least one product contained in the bucket.

Abstract: A vertical packaging machine (10) comprises a carcass having a substantially quadrangular plan, a forming tube (12) mounted on one side of said carcass and adapted to create packages of a product through the use of a continuous advancement film (13) supplied by a reel (14) mounted on a shaft (16) and arranged in a housing provided in a side of the carcass adjacent to that on N which said forming tube (12) is mounted, the unwinding of said film from said reel being performed by a motor (17) equipped with an appropriate means for controlling the unwinding of said film (13), said carcass being further equipped with a horizontal flat surface (21) on which the film (13) unwound from said reel is made to transit and change direction by 90° for being then directed towards said forming tube (12).

Abstract: Measuring device (1; 15) for determining the composition of the liquid phase of a liquid-gas mixture includes a duct (2) defining a flow direction (X) of the mixture parallel to the longitudinal development axis (Y) of the duct (2) and a measuring element (4) arranged in the duct (2) and suited to determine the composition of a liquid layer that flows in contact with the internal surface (3) of the duct (2). The internal surface (3) of the duct (2) includes an intercepting surface (5, 5?) suited to convey part of the liquid layer towards the measuring element (4), arranged so that it is incident on the flow direction (X) and developed according to a conveyance trajectory that has a helical section and whose tangent to the outlet end (7, 7?) intersects the measuring element (4).
