Abstract: A labeling machine for prism-shaped bottles having an axially-offset neck, comprising a first carousel, which conveys the bottles to a first labeling assembly, which applies the labels to one of the faces, and a second carousel, which conveys the bottles to a second labeling assembly, which applies the labels to an opposite face; the carousels are connected in series by at least one pair of bottle transfer devices.

Abstract: A bottle labeling machine, comprising a rotating carousel provided with a supporting structure for pans on which the bottles rest and comprising input and output star conveyors, the input and output star conveyors being arranged at a fixed elevation, the rotating carousel being provided with means suitable to change the elevation of the pan supporting structure.

Abstract: A device for centering a container provided with a reference on a pan in a labeling machine, comprising elements adapted to determine, by making contact with the reference provided on the container, the locking of the container in the direction of rotation of the resetting motion, leaving the container free to rotate together with the pan when the pan rotates in the direction of the motion that occurs during labeling.

Abstract: A bottle labeling machine, comprising a rotating carousel provided with a supporting structure for pans on which the bottles rest and comprising input and output star conveyors, the input and output star conveyors being arranged at a fixed elevation, the rotating carousel being provided with means suitable to change the elevation of the pan supporting structure.

Abstract: A device for orientating bottles in labeling, filling, capping machines and the like, comprising a turning element which is adapted to turn the bottles about an axis perpendicular to the conveyor belt until the intended position is reached, by making contact with the body of the bottles, and coordinated devices which are adapted to keep the head of the bottles in position during the orientation operation.

Abstract: Operation control device for photography printing and developing machines, wherein the images of negatives are projected on photographic paper, by exposing it, and wherein the exposed paper is then developed and printed. Device comprising central control means (23) communicating with the control unit (19) of each printing and developing machine (6, 7) and displaying means (monitor 17) for the negatives of each machine, contained into magazines (25), wherein such central control means (23) are adapted to set the data of the characteristics of the operative cycles to be carried out in the different machines and to control such cycles, independently from those of the other machines, and to activate at random every machine as soon as one operative cycle is ended, in order to permit a subsequent cycle to be carried out.

Abstract: On a plant for continuous development of photographic material, comprising a plurality of operative units (6, 7, 8, 9, 10) for the photographic material treatment, there are provided a first and a second autonomous and independent adaptation units (12, 15), which can be interposed removably among these operative units so as to compensate the different photographic material advancement speeds between the one and the other unit, by controlling suitably the photographic material advancement devices of each adaptation unit and the operative units adjacent thereto. Advantages of the invention system include that the dangers of damagings and/or breakages of the photographic material are avoided during the advancement thereof among the various plant operating units and adaptation units, while promoting a rational and reliable arrangement and operation of the same plant.

Abstract: Transfer storage buffer apparatus for interconnecting processing machines for the development and printing of continuous-strip photographic material includes a plurality of rollers arranged on a fixed upper carriage and a movable lower carriage, respectively, at such positions that the material is alternately conveyed over the upper and lower rollers. The lower carriage is driven in both its upward and downward movement by an actuatable and adjustable elevating mechanism in the form of a pulley arrangement. The pulley arrangement includes a bracket sliding vertically on a fixed vertical support and locked to a flexible continuous-transmission element, and a lower pulley and an upper pulley over which the continuous-transmission element extends. A motor supplies power to the elevating mechanism to control the force under which the lower carriage is moved, to thereby regulate the tension on the photographic material.

Abstract: A device in cludes two mechanisms mounted beside the two longitudinal sides of an adapter supporting the customary feelers of a test apparatus. Each mechanism is adustable transversely on the adapter, and includes a number of pulleys having coplanar parallel axes and engaging a respective edge of the printed circuit plate of an electronic module for testing. The mechanisms are activated by a common actuator against the action of springs so as to bring the plate into contact with the feelers. The pulleys of each mechanism are rotated simultaneously by a belt activated by a toothed drive roller so sized as to mesh with the respective mechanism regardless of the position of the same.

Abstract: The invention relates to a self-assembling telescopable structure comprising a plurality of members which can be slipped and unslipped into and from each other. For the assemblage and disassembling of the structure releasable fastening members are provided for the several component parts and reversible lifting means acting between the internal component part and its next intermediary component part.By outstretching such means it is possible to effect the unslipping of the internal component part from its next. By subsequently fastening the internal component to the external one or to an intermediate component and binding mutually the other intermediate components, it becomes possible, by contraction of said lifting means to have the mutually bound intermediate components into the unslipped internal component part. By repeating these steps, the structure is assembled, whereas, by reverting the step sequence the disassembling of the structure is obtained.
