Abstract: A system, a computer readable storage medium including programs, and a computer-implemented method for displaying objects in a graphical user interface of a device are described. A vision test is presented in the graphical user interface of the device, the vision test including vision test objects used to test a visual acuity level of a user of the device. Input is received from the user identifying the user's ability to see at least one vision test object in the vision test. Display settings corresponding to the input received from the user are identified. Objects in the graphical user interface are displayed based on the display settings.

Abstract: A system, computer-readable storage medium storing at least one program, and a computer-implemented method for presenting information to a user are presented. Information to be presented to the user is received, where the information has a predetermined format. An identifier for the user is obtained. A visual acuity for the user is obtained using the identifier for the user. The predetermined format is adjusted based on the visual acuity of the user to produce an adjusted format. The information is presented to the user using the adjusted format.

Abstract: A fluid delivery device for a printing machine includes a rotating roller having a roller surface with a roller radius of curvature, the roller surface carrying a fluid film, and a metering element having an edge for splitting the fluid film and a first concave surface facing the roller surface. The metering element is movable with respect to the roller surface.

Abstract: A process for removing water from sludge has the steps of passing the sludge through a chamber, injecting carbon dioxide gas under pressure into the chamber as the sludge passes through the chamber, and flashing the carbon dioxide-injected sludge through an orifice into a vessel so as to release carbon dioxide gas from the sludge. The flashed sludge is returned to a digester or is dewatered to remove water from the sludge. The carbon dioxide gas is injected at no less than 14.7 p.s.i.a. of pressure.

Abstract: A device for controlling delivery of an amount of fluid has a first rotating device having at least one peripheral first fluid transfer section, a second rotating device having at least one peripheral second fluid transfer section, and a device for setting a phase between the first and second fluid transfer sections. The device may be used for providing ink or dampening solution in a printing press.

The flashed sludge is dewatered to remove water from the sludge. The carbon dioxide gas is injected at no less than 25 p.s.i.g. of pressure.

Abstract: A method for controlling a chill roll system in a web printing press includes calculating, based on a web inlet temperature of a web entering a first chill roll of the chill roll system, a dew point temperature of an ink solvent vapor of ink printed on the web is calculated. The inlet coolant temperature of coolant entering the first chill roll is set to temperature value near the calculated dew point temperature. Using a heat transfer model, the flow rate of the coolant through the first chill roll needed to maintain a temperature rise of the coolant through the first chill roll below a predetermined value is determined. The method prevents post-chill marking by sufficiently cooling the web, and sets chill roll temperature profiles to avoid solvent condensation on chill roll surfaces and thereby avoid condensate marking.

Abstract: Apparatus for removing piping from the ground comprises a cable (1) which has pipe engaging means (2) disposed along its length. The pipe engaging means (2) are arranged such that the cable (1) is insertable into a pipe (3) in one direction but that attempted withdrawal of the cable (1) in the opposite direction relative to the pipe (3) causes the pipe engaging means (2) to jam the cable (1) in the pipe (3). The pipe (3) can then be pulled from the ground, the pulling force being distributed along the length of the pipe (3).
