Abstract: An apparatus for measuring the inner volume of a cavity. According to one embodiment the apparatus comprises a hollow body coupleable to the cavity, such that the inner volume of the cavity and the inner volume of the hollow body are communicated. A solid body is housed in the hollow body. A detector monitors the position of the solid body. A processor determines the inner volume of the cavity which is calculated from the oscillation of the solid body according to the volume of gas inside the cavity.

Abstract: Container capacity control system, which is comprised of a first horizontal linear guide (3) where there is a clamp head (13), which can move horizontally and rotate on the horizontal plane and which holds a first clamp (1) and a second clamp (2) for the input and output of an empty container (b1) respectively; a second horizontal linear guide (4) where means for the total filling or predetermined partial filling move; some weighing scales (5), which weigh the container (b1) empty and totally full or partially full with the predetermined amount, sending the weight data to a microprocessor, which controls the programmed system, so that it distinguishes between full-to-the-brim containers and containers partially filled, calculating the capacity based on the weighing data.

Abstract: Bottle extractor for hollow glass moulding machines, of the type that have bottle handling fingers comprising, a head joined to a fixed position spin axis and which includes at least one fluidic action cylinder, whose rod is joined to the fingers, the head having a mobile head supporting the fluidic action cylinder(s); a head base joined to the fixed position spin axis and nut-screw means to move the mobile head with respect to the head base.

Abstract: Container palletiser, of the type that have an arm equipped with n degrees of freedom, which sustains a head equipped with m degrees of freedom respect to the arm, and an accumulation table for the containers to be palletised, the head being a drawing head, which is comprised of a drawing frame equipped with a device to move horizontally with respect to the head and a supporting platform placed under the drawing frame; equipped with a device to move horizontally with respect to the head. Applicable in the glass industry.

Abstract: Improved programmable sequencer for electric valves used in a hollow glass manufacturing installation, consisting of a processor and a power source connected respectively by optic fiber and conventional cables with a distributor provided in the vicinity of the installation, which consists of a converter of optic fiber signals to electrical signals, in communication with an electronic block provided in the installation which consists of a series/parallel, parallel/series converter that communicates with an electronic power block abutting against the electric valve block that it is desired to sequence.
