Abstract: A machine for the orderly storage and delivery of banknotes comprises an input of banknotes (11), an output of banknotes (19), a path (12, 14, 15, 18) of sequential flow of banknotes between the input and the output, devices (13) for detecting the characteristics of the banknotes along said path and a plurality of compartments (20) for the internal storage of the banknotes. Each compartment (20) of the plurality is a sequential drum compartment and winding belts and the compartments of the plurality are divided into two series of compartments (16, 17). The internal path of the banknotes between input and output comprises a sorting section (15) along which the inputs/outputs of the two series of compartments of the plurality face each other alternately on two opposite sides, each input/output being associated to sorting means (25) that can be commanded for the deviation of the banknotes between the sorting path (15) and the compartment (20) associated.

Abstract: The automatic banknote selection and delivery safe consists of an armored boxed frame in one upper zone of which is mounted a first banknote acceptance device from which departs a first banknote grasping and conveyance means paths towards a first screening station thereof with associated detection means followed by a second station for sight sensing of the banknotes collected and alternate sending to a restitution door or to a third station of withdrawal from said first path and routing towards an underlying second path of sorting in a containment storage unit divided in preselectable modular tanks with there being provided inspection means for the correct positioning of the banknotes, removable cartridge means for accumulation of banknotes and at least one door directly opening on the exterior equipped with the usual electronic selection means for access to the automatic banknote delivery.

Abstract: A diffuser (D) for atomizers or mist blowers of treatment liquids in agriculture, includes a large tube (1) fed with air under pressure, ending into a narrow fan-shaped opening (2), and elements to cause the treatment liquid to flow into the fan-shaped opening (2) at a very low pressure. The elements include a plurality of sectors (3) for liquid distribution, each of them consisting of two straight tube lengths (4) of synthetic plastic material, provided with gauged holes (5) and mutually connected so as to form a very wide angle between them, and substantially at 90.degree. with a feeding duct (6). The sectors (3) are positioned in succession, in one or more side-by-side rows, along the narrow fan-shaped opening (2), substantially at its center.

Abstract: Equipment and method for automatically changing tools on hobbing machines. The machines are of the type equipped with a bedplate to which are connected a pair of uprights, the first of which for supporting a work head and the second of which for supporting a cutter head. The cutter head is rotatable around a horizontal axis and supports horizontally a hob at the extremities thereof. The equipment includes guide means provided in the cutter head, parallel to the axis of the hob, and a support for at least one extremity of the hob is slidable inside the cutter head along the guide means. The support is also displaceable, without being withdrawn from the cutter head, by an amount sufficient to free the two extremities of the hob from the cutter head. The equipment includes also an independent frame fixable to either one of the pair of uprights, and supporting grasping means located above the cutter head.

Abstract: Disclosed herein is a gear cutter that comprises a bedplate, a first block or column mounted on the bedplate, designed to carry a tool, and a second block or column also mounted on the bedplate, designed to carry in an axis of rotation a piece to be cut, and wherein provision is made for a device for detecting variations, due to the thermal expansion of the bedplate, in the distance the first block is apart from the second block, and for drive means interlocked to the said detection device and connected to at least one of the said blocks in order to compensate continuously for variations in the spacing in between the said blocks.

Abstract: Gear cutting apparatus comprises a hob 9 carried by a radial slide 1 and an axial slide 16, which are moved by independent d.c. motors 20 and 17. A main variable-speed motor 2 on the radial slide 1 is kinematically connected to the hob 9 and to a turntable 10 for the workpiece. The speed of movement of the axial slide is controlled by an electronic circuit which receives signals from dynamo-tachometers kinematically connected respectively to the turntable 10 and to the motor 17 moving the axial slide 16. The movement of the radial slide 1 is controlled in accordance with that of the axial slide 16 by another electronic circuit.
