Abstract: The present disclosure is related to techniques for the inspection of joints and repairs in pipelines. In this scenario, the a method is provided for the inspection of joints in composite pipes and of composite repairs in metallic pipelines, comprising the steps of (i) emitting a series of acoustic wave pulses, at different frequencies, from a collar of acoustic transducers positioned at a predetermined distance from a joint or repair to be inspected, (ii) recording, in a time interval subsequent to the emission, echoes of wave displacements to the repair or joint in each of the transducers in the form of an A-Scan, and (iii) generating a flattened C-Scan image, through a CSM, for each frequency of pulse emission from the collar of acoustic transducers. The disclosure further provides a system for inspection of joints in composite pipes and of composite repairs in metallic pipelines associated with the provided method.

Abstract: A printing apparatus includes a print head to print a print material on a support; a feed device feeding the print material to the print head; and a recirculating unit generating a recirculation of the print material through the print head and having a first container of the print material placed upstream of the print head, a second container of the print material placed downstream of the print head, a first recirculating sub-unit generating a first flow of the print material from the first container to the print head and the second container, and a second recirculating sub-unit transferring the print material from the second container to the first container, wherein the first and second containers are both maintained under two distinct negative pressures.

Abstract: A printing apparatus on a print support includes a print head to print on said print support a print material; a feed device to feed the print material to the print head; and a recirculating unit to generate a recirculation of the print material through the print head and having a first container of the print material placed upstream of the print head, a second container of the print material placed downstream of the print head, a first recirculating sub-unit to generate a first flow of the print material from the first container to the print head and the second container, and a second recirculating sub-unit to transfer the print material from the second container to the first container, wherein the first and second containers are both maintained under two distinct negative pressures.

Abstract: A printing apparatus includes a support plane to support at least a print support; at least two printing groups aligned along a longitudinal axis, and each provided with at least a printing head; a support structure provided to support said printing groups above said support plane, at least a moving device to move said printing groups towards/away with respect to said support plane, at least two containment devices each associated with respective positioning means, and configured to collect printing liquid form said printing heads.

Abstract: Printing unit comprising at least a printing head, a support plate to which said printing head is associated, and at least one positioning member associated to the support plate and to the printing head to adjust the reciprocal position of the latter two; the support plate defines an adjustment plane with respect to which the printing head is positioned; the positioning member comprises at least an actuation device which can be selectively actuated above the adjustment plane and a kinematic conversion device configured to convert the actuation of said actuation device into an adjustment of the position of the printing head with respect to the support plate in at least one direction lying on the adjustment plane; the actuation device is associable with a cam element able to engage in a suitably shaped seating made in the printing head.

Abstract: A printing apparatus comprising a support plane on which a substrate to be printed can be positioned and a plurality of printing units provided with at least one printing head; each of the printing units is housed on at least one support plate positionable in proximity to the substrate to be printed and crossed by the printing head of the printing units; the apparatus also comprises removable positioning devices of each printing head and therefore of each of the printing units on the support plate; the removable positioning devices are able to hold the printing head on the support plate and allow their possible removal from the support plate; the printing units are configured to be aligned in a modular manner in at least a determinate direction, so as to form at least a printing battery.

Abstract: The following description sets forth antisense (AS) oligonucleotides (ODNs) complementary to the primary transcript of the human c-fes protooncogene and their use to inactivate said transcript. All-trans retinoic acid (ATRA) is reported to be used as a differentiation inducer on cells pretreated with said AS-ODNs to induce apoptosis of leukemic blast cells.

Abstract: A nuclear imaging device comprising a plurality of scanning heads spaced apart in a predetermined configuration with the aid of a support member that permits the individual scanning heads to scan in parallel, antiparallel, and tomographic modes. The support member which is driven in both X and Y directions is mechanically connected with the stylus of a graphical X-Y plotter via a backlash linkage. Displays are provided wherein the color of the ink dot on printed paper or the intensity of the light projected on photographic film are related to the nuclear particle count in a preselectable manner.
