Abstract: An ink jet print head assembly includes a carrier body, plural pistons, and a printing plate. The carrier body has an ejection side configured to face an object to be printed upon. The pistons are coupled with the carrier body. The printing plate is coupled with the ejection side of the carrier body and includes a diaphragm plate. The printing plate is configured to hold a fluid to be printed on the object on a side of the diaphragm plate that is opposite of the pistons. The printing plate includes orifices through which the fluid is ejected from the printing plate and onto the object being printed upon. The pistons are configured to actuate in ejection directions in order to engage the diaphragm plate and cause the fluid to be ejected from the orifices of the printing plate along printing directions. The ejection directions in which the pistons are actuated are transversely oriented with respect to the printing directions in which the fluid is ejected from the printing plate.

Abstract: A Two-way valve for regulating and measuring the flow rate of a fluid through a header (1) and a branched duct (2,2a) inside the header itself. The valve (10a, 10, 11, 11c) which shuts off the aperture (2b) of the branched duct (2) is internally hollow and movable axially by an associated actuator (13). Discs (30, 130) for detecting the pressure exerted by the flow of the fluid are integral with elements (20, 40) movable axially against the opposing action of a spring (60, 160) and form part of an instrument (70, 170) for measuring the flow rate. The valve comprises a head (10a), on the side surface of which recesses (10d) are formed.

Abstract: A conformable marking tape having improved mechanical properties comprises a support base and a top-coat layer, the support base comprising a highly saturated acrylonitrile elastomer grafted with a zinc salt of methacrylic acid. The top-coat layer preferably comprises a polyurethane resin having about 50 to about 65% by weight of rigid segments and about 35 to about 50% by weight of flexible segments. The rigid segments are derived from diisocyanates and aliphatic and/or cycloaliphatic chain extenders, and the flexible segments are derived from polymeric compounds having at least two active hydrogen atoms and having weight average molecular weights ranging from about 400 to about 4000.

Abstract: A power driven valve actuator includes a thermostatic device which is movably supported in a housing to accommodate overtravel of a thrust member against the stem of the valve resulting from excess expansion of a thermostatic element enclosed in the thermostatic device and heated by a heating device. Movement of the thermostatic device trips a dust-tight switch to interrupt power to the heating device, and a spring engaging the thermostatic device returns the thermostatic device to a starting position, so that whenever heat is called for by the thermostat, the thermostatic device cycles in a reciprocating motion within the housing after the valve has been fully opened. The heating device comprises an electric resistance heating element placed in contact with a thermal enclosure of the thermostatic element and covered by an insulating material.

Abstract: The described method and apparatus are relative to the indirect measurement of thermal energy delivered to numerous heating elements, part of one or several zones, for instance all the radiators in an apartment or all the radiant panels of single family quarters. The apparatus consists of a temperature sensor which outputs an electric signal depending upon the temperature of the carrying fluid in which it is immersed and corrected as a function of the type of heating unit used (radiators, fan-coils, radiant panels, convectors, etc.
