Abstract: A servovalve pilot stage (100) comprises a piezoelectric actuator (130) joined to a flow guide (132) and feedback wire (136) for connection to a main stage spool valve. The flow guide (132) and the piezoelectric actuator (130) may be integral.

Abstract: A compressor adapted to compress a working fluid includes a housing surrounding a compressor wheel and a backplate connected to the housing and enclosing the compressor wheel within an interior space of the housing. A cooling fluid conduit is fluidly connected between a cooled and compressed source of working fluid downstream of the compressor and the interior space of the housing of the compressor at a location between the compressor wheel and the back plate. A pressure differential created when the compressor is operating draws a flow of cooled, compressed charge into the interior space of the housing, which flow passes over and convectively cools said compressor wheel before mixing with a main compressor flow and being provided back through the compressor outlet.

Abstract: A security document or device (30) is provided which has a substrate (31) including at least one layer (35,37) of polymeric material and an optical component formed by at least one orientating (PPN) layer (34) and at least one liquid crystal polymer (LCP) layer (36) in contact with the orientating layer (34). An intermediate prime layer (38) is provided between the optical component and the substrate (31) which improves the adhesion of the optical component to the substrate (31). The prime layer (38) may include a hydroxyl terminated polymer which is cross-linked by a multifunctional isocyanate. A security document with such a prime layer between the optical component and a polymeric surface of the substrate is more robust and able to withstand rough treatment without significantly affecting the optical properties of the optical component.

Abstract: A method of producing a security document or article including a substrate (100), which is transparent at least to visible light, and a diffractive optical microstructure (112). The method includes applying an opacifying layer (102) to at least one surface of the transparent substrate (100). An area of the opacifying layer (102) is exposed to laser radiation (108) to ablate apertures (110) in selected portions of the opacifying layer (102), thereby forming a diffractive optical microstructure (112) on the surface of the substrate (100). The laser radiation may be patterned prior to exposing the opacifying layer (102), for example by passing the radiation through a mask (104). Alternatively, a focussed or collimated laser beam (206) may be directed onto the selected portions of the opacifying layer (102). Laser radiation may be directed onto the opacifying layer (102) either directly, or through the transparent substrate (100).

Abstract: A security document (1) comprises a substrate (10) including at least one layer of. polymeric material (12, 26) and containing an upconverting fluorescent material (18), and at least one coating (14) containing a refractive pigment applied to the substrate (10). When the security document is exposed to electromagnetic radiation of a particular wavelength, e.g. infra-red, the upconverting material (18) emits a signal of electromagnetic radiation of a shorter wavelength, e.g. visible light, and the coating (14) containing the refractive pigment enhances the signal.

One method includes applying an opacifying layer (102) to at least one surface of a transparent substrate (100). An area of the opacifying layer (102) is exposed to laser radiation (108) to ablate apertures (110) in selected portions of the opacifying layer (102), thereby forming a diffractive optical microstructure (112) on the surface of the substrate (100).

The composition is coated on a substrate then optionally treated to initiate a free radical reaction.

Abstract: The invention is a composition made by mixing a multifunctional acrylate with an aminofunctional silane and an ethylenically unsaturated acid to form a reaction product, optionally dissolved in a solvent, characterized in that the multifunctional acrylate has a molecular weight of from about 100 to about 3000. The composition can be coated on a substrate, then optionally exposed to moisture and treated to initiate a free radical reaction. The invention can be applied to a variety of substrates used in packaging applications. The reaction mixture can further be cured by heating in the presence of moisture. The free radical reaction can be initiated by electron beam irradiation, ultraviolet radiation, gamma radiation, and/or heat and chemical free radical initiators.
