Abstract: The invention provides micro-optical and fiber based solutions to the problem of reflective telescopes with secondary or tertiary obscurations, and further, it ameliorates secondary or tertiary obscurations in compact reflective fiber-coupled telescopes configured as optical transmitters. One solution uses a custom hollow optical fiber and lens system to generate an annular beam that would not be obscured by the telescope secondary obscuration. Another solution uses a fiber coupled micro-axicon lens assembly to achieve the same result.

Abstract: An aqueous alkaline developer for use with an imaged lithographic printing precursor comprises an aqueous alkaline medium, sodium metasilicate, a steric or electrosteric stabilizer, and a rinse aid or a phase stabilizer. It is suited for developing a lithographic printing precursor comprising, on a substrate, a coated and dried layer of a radiation-sensitive composition comprising one or more acetal resins. The developer may further contain a moderator, a dispersing agent capable of solvating a hydrophobic image colorant, and a wetting agent. The acetal resin of the precursor may be derived from polyvinyl alcohol by condensation with aldehydes. The imageable element is imageable by radiation, preferably infrared radiation, and provides good sensitivity for use in lithographic applications, such as conventional imaging systems, computer-to-plate systems or other direct imaging elements and applications when treated with the developer.

Abstract: A saturable absorber Q-switch includes a monocrystalline lattice having the formula Mg1-xCoxAlyOz where x is greater than 0 and less than 1, y is greater than 2 and less than about 8, and z is between about 4 and 13. The lattice has tetrahedral and octahedral positions, and most of the magnesium and cobalt occupy tetrahedral positions. In one embodiment, the molar ratio of aluminum to the combined amount of magnesium and cobalt in the monocrystalline lattice can be controlled during growth of the monocrystalline lattice to thereby form a saturable absorber Q-switch that exhibits a 4T1 spectrum for the cobalt ion of at least about 1544 ?m.

Abstract: A static mixer conduit comprises a longitudinally elongated conduit having tabs that are arranged with respective first edges adjacent the conduit wall and respective opposed second edges that are spaced radially inward from the conduit wall. These tabs are operable as fluid foils so that with fluid flowing through the conduit, greater fluid pressures manifest against the tab's upstream faces relative to reduced fluid pressures against their downstream faces. The resultant pressure difference in the fluid adjacent, respectively, the mutually opposed faces of each of the tabs causes a longitudinal flow of fluid through the conduit over and past each said tab to be redirected. As a result of the redirection, there is introduced a radial cross-flow component to the longitudinal flow of fluid through the conduit.

Abstract: A flow-through photochemical reactor includes a reactor body, that circumscribes a longitudinally extending channel having a generally annular cross section. This channel accommodates fluids passing between an inner wall of the reactor body and an outer wall of a photon-transmitting tube that is housed internally thereof. In addition, the reactor includes mechanically static, fluid-dynamic elements for passively inducing substantial turbulent flow within a fluid as it passes through the channel. This arrangement substantially increases the uniformity of the fluid's exposure to photons radiating from a source within the tube into the fluid an it is conducted through the channel.
