en Method and apparatus for orienting magnetic flakes By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT The invention relates to a method of aligning magnetic flakes, which includes: coating a substrate with a carrier having the flakes dispersed therein, moving the substrate in a magnetic field so as to align the flakes along force lines of the magnetic field in the absence of an effect from a solidifying means, and at least partially solidifying the carrier using a solidifying means while further moving the substrate in the magnetic field so as to secure the magnetic flakes in the carrier while the magnetic field maintains alignment of the magnetic flakes. An apparatus is provided, which has a belt for moving a substrate along a magnet assembly for aligning magnetic flakes. The apparatus also includes a solidifying means, such as a UV- or e-beam source, and a cover above a portion of the magnet assembly for protecting the flakes from the effect of the solidifying means.

en Dampening fluid deposition by condensation in a digital lithographic system By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT A system and corresponding methods are disclosed for depositing of a layer of dampening fluid to a reimageable surface of an imaging member in a variable data lithography system by way of condensation. Dampening fluid in an airborne state is introduced proximate the reimageable surface in a condensation region. Conditions in the condensation region are such that the airborne dampening fluid preferentially condenses on the reimageable surface in a precisely controlled quantity, to thereby form a precisely controlled layer of dampening fluid of desired thickness over the reimageable surface. Among other advantages, improved print quality is obtained. Full Article
en Method and an apparatus having a compressible collar for thermally treating a photosensitive precursor By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT The invention pertains to a method and apparatus for preparing a printing form from a precursor, particularly a method and apparatus for preparing the printing form by thermally treating a photosensitive precursor having a photopolymerizable layer. The method and apparatus includes heating the photosensitive precursor to a temperature sufficient to cause a portion of the layer to liquefy, contacting the precursor with a development medium to remove the liquefied material, and supporting a development medium with a core member adjacent an exterior surface of the photosensitive precursor, wherein a compressible collar of a closed-cell foam having a Poisson's ratio of less than 0.4 is disposed between the core member and the development medium.

en PHASE NOISE IMPROVEMENT TECHNIQUES FOR WIDEBAND FRACTIONAL-N SYNTHESIZERS By www.freepatentsonline.com Published On :: Thu, 29 Jun 2017 08:00:00 EDT The disclosure provides a frequency synthesizer. It includes a PFD that generates an up signal and a down signal in response to a reference signal and a feedback signal. A charge pump generates a control voltage in response to the up signal and the down signal. A low pass filter generates a filtered voltage in response to the control voltage. An oscillator circuit generates an output signal in response to the filtered voltage. A feedback divider is coupled between the oscillator circuit and the PFD, and divides the output signal by a first integer divider to generate the feedback signal. A sigma delta modulator (SDM) generates a second integer divider in response to the feedback signal, the reference signal, the output signal and the first integer divider. A digital filter is coupled between the SDM and the feedback divider, and filters quantization noise associated with the SDM. Full Article
