Abstract: Excellent development of planographic printing plates can be achieved by exposing an imaged, negative working, photopolymerizable coating to a high pressure stream of essentially untreated tap water, whereby the water completely removes only the less cohesive and adhesive (e.g., partially polymerized) regions to the substrate, thereby directly producing a printing plate having an image pattern of highly cohesive and adhesive, oleophilic regions of the coating and hydrophilic regions of the substrate. The coating removal mechanism appears to be due entirely to ablation. The high pressure stream is preferably delivered to the plate through at least one nozzle having a discharge pressure greater than about 200 psi. Each nozzle preferably has a spray pattern that impinges the plate over a substantially rectangular region of the plate, and the nozzle and plate translate relative to each other.

Abstract: Disclosed is an electronic device including a first and second housing. Each housing may include at least one display that may be on a front face or a rear face of the housing. A hinge may couple the first housing and the second housing and may be configured to allow the first housing and the second housing to change their orientation relative to one another with a twist motion around an axis defined by the hinge. With a twist motion, the housings can form a closed configuration and at least one open configuration. Multiple display screen and communication modes may be enabled based on a relative orientation of the housings. In this way, a “twist phone” form factor may provide the shape and function to add and/or improve features that may be desirable to a user.

Abstract: Excellent development of photosensitive coatings on planographic printing plates is achieved by directing a dynamic flow of fresh alkaline developer solution that impinges on a target area of the coating extending the width of the plate and floods the target area with a turbulent flow. At sufficient volumetric flow rate, the developer solution at the target area is constantly displaced during the development time, whereby no boundary layer forms on and travels with the plate during the development time and thus the target area is always in contact with fresh developer solution.

Abstract: An imaged plate processor for covering the imaged coating with a turbulent flow of fresh developer solution for a short dwell time, and which preferably can be modified by the end user for development of a wide range of plates. The processor comprises a flat support surface for the plate, a plate feeder to the support surface, a plate transporter, and a nozzle array oriented to discharge developer solution onto a plate as the plate moves along the support surface. A source of fresh developer solution is connected to a pump for pressurizing the developer in the nozzle array in the range of about 5 to 250 psi, whereby fresh developer solution is directed from the nozzles as a pressurized flow pattern transversely onto the plate. A continual flow of fresh developer solution impinges on successive areas of the plate. Adjustable variables for accommodating a variety of plates include at least one of spray pressure and plate transport speed.

Abstract: A process for developing an imaged lithographic printing plate, including the step of delivering developing fluid to the plate at a high volumetric flow rate for a short dwell time such that the non-image is completely solubilized while the image remains unaffected by the developing fluid. At sufficient volumetric flow rate, the developer solution at the target area is constantly displaced during the development time, whereby no boundary layer forms on and travels with the plate during the development time and thus the target area is always in contact with fresh developer solution.

Abstract: In a system and process for developing an imaged plate by contacting the plate with an alkaline developer, contained in a developer tank having a cover spaced over the developer level, the space between the developer level and cover is maintained at a concentration of carbon dioxide below ambient for a substantial portion of each day. Preferably, active carbon dioxide control is implemented in the space at least during idle periods, to maintain the concentration of carbon dioxide below about 100 ppm, preferably in the range of 0-10 ppm. The system has a first conduit with an extraction port in the space and a second conduit with a return port in the space. A canister of carbon dioxide scavenger material is fluidly connected between the conduits. A motorized air handling device fluidly connected with the conduits and scavenger material, draws air out of the space, passes the drawn air through the canister, and delivers the scavenged air back into the space.

Abstract: A susceptor composition that can bond two or more layers or substrates to one another and that can be used to coat or cut a substrate. The susceptor composition is activated in the presence of radio frequency (RF) energy. In one embodiment, the susceptor composition of the present invention comprises a susceptor and a carrier. The carrier and susceptor are blended with one another and form a mixture, preferably a uniform mixture.

The susceptor is an ionic or polar compound and acts as either a charge-carrying or an oscillating/vibrating component of the susceptor composition. The susceptor generates thermal energy in the presence of an RF electromagnetic or electrical field (hereafter RF field).

Abstract: A portable fluorescence scanner has single or multiple excitation sources at various non-visible wavelengths. If multiple non-visible sources are used, they are disposed in alignment with a selector controllable to select any of the sources. The selected beam illuminates a target article which, if authentic, has been marked with certain fluorescent material(s), and fluorescent light returns, along an optical path that may include a beam splitter, to a photodetector whose signal is processed and analyzed by a digital signal processor (DSP). The DSP also either controls the deflector or receives a signal from a transducer indicating the deflector's orientation, or both. The invention may be configured as a hand-held fluorescence scanner. Multiple UV laser diode or UV LED sources can be arranged in an array, which may be linear.

Abstract: A plunge-type router is disclosed which has a base and a head assembly that is vertically adjustable by an adjusting mechanism. The plunge router includes an electronic control system with a digital display and control functionality that enables the router to accurately determine a baseline or zero position for a router bit installed in the router and permits the user to input a depth of cut value or other predetermined command. The control system then automatically causes the motorized adjusting mechanism to go to the appropriate position. The electronic control system enables the storage of multiple depth settings as well as multiple step or macro operations. In this regard, macros may be run to provide incremental cutting necessary for performing multiple passes to achieve a relatively deep depth of cut.
