Title: Multiple jet liq sprayer - auxiliary chamber with valves in parallel with jets ensures constant pressure for reduced number of jets
IPC: B05B9/04
Filed: 1974-12-19
Abstract: The liquid spraying arrangement, e.g. for applying bitument to a road surface, with a set of jets carried by a delivery pipe through which the liquid is forced by a constant delivery pump has the liquid connection at the centre of the pipe and the return flows from the two ends are connected to an intermediate chamber for eventual return to the supply tank. This chamber is divided into two compartments by a partition (12). In this partition is embedded a set of valves (21) equal in number to the jets and having the same capacity. each time a jet is closed when the number of jets is reduced, the corresponding valve is closed, thus interrupting the return flow through the intermediate chamber, so that pressure remains constant whatever the number of jets employed.

Title: Grape hopper with archimedean screw - which rotates in one direction or the other according to the must hydrometric degree
IPC: A23N1/00
Filed: 1975-02-10
Abstract: Hopper for grapes has a V-shaped cross-section with a rounded base which houses an Archimedean screw driven by the electric motor through a reducing gear. The two ends of the screw each form the shafts of two pumps so that they are driven by the same motor; each pump has an inlet while the outlets are connected to rigid pipes and to diaphragm valves each of which is connected to the pipe system respectively, which leads to a collecting tank. When the valves are fed with compressed air, the pipe systems remains connected; when the air supply is stopped, as during the weighing operation, all connection with the hopper is broken. The hopper is suspended by the girder from a conventional weighing device, indicated by the rectangles. A crusher for the grapes is arranged above the hopper and below the funnel it is provided with a probe for a hydrometer for use with must. This probe is linked to the motor control so that the motor rotates in one direction when the must degree does not attain a pre-determined level and the grape juice leaves by the outlet, and in the opposite direction when the must degree exceeds the threshold. The hopper associated with a weighing device takes up a reduced amt. of space; operation is partic. efficient and the cost low. According to the quality of the grapes the prod. can be directed in two different directions, depending upon the direction of rotation of the screw.
