Abstract: The invention relates to a method for producing knitted goods in general, hose in particular, with tridimensional effects or shaped goods, preferably fitted with at least one pocket automatically produced with the continuous motion of the needle cylinder. The usual knitted fabric production is modified by excluding, according to a preestablished order, sequences of needles (retaining the last loop or stitch) that are preferably alternated (1:1-2:2-3:1-etc.), even by groups. The knitted tube production goes on, even over several courses, with a differentiated growing, i.e. regions having full needles or ribs and regions having non-full needles or ribs, forming knitted layers or tubes (5, 6) concentric with the inner knitted tube folded upwardly and only partly interstitched or closed in the horizontal direction. The remaining part, which is open, corresponds to the two-layer pouch-like pocket, being the object of the invention.

Abstract: For the continuous manufacture of a twin-wall pipe having a pipe socket and consisting of a smooth internal tube and an external tube, which is welded together therewith and provided with transverse grooves, two extruders are provided, which extrude an external tube and an internal tube via a joint crosshead. Switches are provided for the production of a pipe socket, by means of which the speed of the extruder is modified in such a way that the mass flow of the melt of plastic material for the production of the external tube is reduced during the production of the pipe socket and/or the mass flow for the production of the inner tube is augmented.

Abstract: A method is disclosed for controlling a multi-nozzle CIJ printhead having a pressure modulator for causing streams of ink emitted from the nozzles to be broken up into individual droplets, and charge electrodes 6 and charge electrode controllers for controllably applying a charge to individual ones of the droplets in each stream. The method involves generating a modulation waveform to operate the pressure modulator to cause droplets to be generated in each stream and operating the charge controllers to supply a charge signal waveform to each charge electrode. The charges applied to the streams of droplets are compared to a reference or threshold value. The number of droplet streams in which the droplet charges exceed the reference or threshold value is determined plural times and an average value for the number is calculated. This step is repeated a number of times and if the average is less than the average previously calculated then the threshold or reference value is reduced.

The punch (15) can be actuated with vibratory motion by means of a solenoid valve (21) controlled by the electronic control unit (3), mounted directly on the punch head (14).

Abstract: A test interface between cable testing apparatus and a coaxial cable for testing the coaxial cable over a frequency range of interest. The test interface comprises a coupler having a cable lead-in opening at a first end and a threaded, connector contact portion near a second end, an insert that abuts an interior shoulder of the coupler proximate the connector contact portion, the insert having a wall portion that projects outwardly toward the second end of the coupler, and a pin constructed and arranged to abut a center conductor of the coaxial cable, the pin substantially centrally positioned within the outwardly projecting wall portion of the insert. The coupler, insert, and pin mechanically and electrically interconnect with a mating electrical connector to provide a reusable electrical connection between the cable testing apparatus and the coaxial cable.

Abstract: An apparatus for conveying conveyable material. The apparatus includes a plurality of cars joined together by a plurality of spacers. The spacers couple the cars a fixed distance apart to form a shuttle. The shuttle is guided along a track between a first position and a second position. In the first position, the shuttle is aligned with a first group of supports. The shuttle in the first position receives conveyable material from the supports. The shuttle in the second position is aligned with a second group of supports. The shuttle disposes the conveyable material from each of the cars carrying the conveyable material to the second group of supports. A drive means repeatedly drives the shuttle between the first position and the second position. The cars remain the fixed distance apart during the driving between the first position and the second position.
