Abstract: A still for distilling an alcoholic liquid such as wine. The still includes a chamber with a copper wall, which is intended to receive an alcoholic liquid, the capacity of the chamber representing a certain volume. The liquid which occupies the volume at the start of the distillation and the chamber wall define, by mutual contact, a first interface with an area to volume ratio that is at most equal to 27 square centimeters per liter. The still also includes one or more copper plates which are disposed inside the chamber and which are submerged in the alcoholic liquid. When the volume is occupied by a liquid, the liquid together with the copper plates define a second interface with an area and the ratio of the total area of the interfaces to the volume is at least equal to 30 square centimeters per liter.

Abstract: A street sweeper comprising a frame adapted for travel over the ground and having at least two transversely spaced wheels, a spring suspension means mounted between each wheel and the frame, a rubbish receptacle mounted on the frame, an elevating conveyor fixed to the frame and having a lower end situated in the region of the two wheels, therebetween, and an upper end situated above the receptacle, and an elongated pick-up rotary brush extending transversally adjacent to the lower end of the elevating conveyor for sweeping the rubbishes on the ground and projecting them into transporting elements of the elevating conveyor, an actuating means associated to each spring suspension means and connected on the one hand to the frame and on the other to a spring of the corresponding spring suspension means, and which, in a first position, compresses the spring to its maximum static load and, in a second position, leaves the spring free of strain, said elevating conveyor being fixed to the frame in a position such tha

Abstract: In this pick-up sweeper, the dirt distributing device (8) is formed by a rotary disk (21) whose axis is substantially vertical and by means (22) for rotating the disk. To improve the filling of the truck (7) the disk (21) may be driven selectively in one or other direction of rotation. Furthermore, the disk (21) is mounted on a support (22) which is itself pivotably mounted about a horizontal axis (23; 27) perpendicular to the longitudinal axis of the pick-up sweeper, and actuating means (26) are connected to said support for causing this latter and the disk (21) to pivot about said horizontal axis.
