摘要:
Localization radiographic films containing rhodium-doped, cubic grain, high silver chloride emulsions can be used in radiographic imaging assemblies comprising intensifying screens for therapy imaging. The average silver halide grain size is from 0.20 to about 0.30 &mgr;m, and they comprise at least 80 mol % chloride based on total silver. These films provide colder image tones and reduced processing non-uniformities.

There is described a method of manufacturing a digital radiography panel. The method includes providing a scintillator screen and spray coating an acrylic adhesive composition on the scintillator screen. A flat panel detector and the scintillator screen with acrylic adhesive composition are compressed together at a force of about 5 psi to about 15 psi, at an atmospheric pressure of about 0.3 Torr to about 100.0 Torr for a time sufficient to affix the flat panel detector to the scintillator screen to form the digital radiography panel.
摘要:
A process for degassing a continuously flowing liquid stream is executed using an apparatus that comprises an air-tight housing, in which is mounted for rotation a centrifuge bowl of circular cross-section and having an inner surface for spreading centrifugally impelled liquid to be degassed and an annular peripheral trough for retaining centrifugally impelled degassed liquid. The liquid stream is fed into the bowl and the degassed liquid is withdrawn through a tube extending from an exit line outside the housing to an open end of elongate cross-section which is positioned within the trough of the bowl and is immersible in the degassed liquid. The pressure of the exiting degassed liquid is measured, the pressure measurement being used to regulate the flow of liquid into the bowl so as to maintain a substantially constant level of the liquid therein. Gas is withdrawn to maintain a sub-atmospheric pressure within the apparatus housing, and the flow of the degassed liquid stream is regulated so that the liquid level in the bowl remains substantially constant.

Processes are disclosed and claimed that allow either purification of nanowire slurries or exchange of liquids in such slurries or both. Such processes avoid the drawbacks of other known methods and are readily scalable to larger production volumes.

An ink jet recording element, prior to image recording, comprising a substantially transparent support having thereon an image-recording layer comprising a polymeric binder, a colorant, and porous, colorless aggregates of particles having a primary particle size of from about 7 to about 40 nm in diameter and being aggregated up to about 300 nm.
摘要:
While preparing a photographic emulsion a conductivity reading is continuously or periodically taken from the batch during creation. The conductivity of the batch is compared to a standard plot of conductivity versus time representing an ideal batch preparation process. When conductivity of the batch deviates from the standard plot by more than a pre-determined level, an operator can discard the batch, compensate for the deviations, identify the cause of the deviation for use in correcting existing processes and procedures or optimizing future procedures, or compensate for the deviations.
摘要:
An apparatus for degassing a continuously flowing liquid stream comprising an air-tight housing, in which is mounted for rotation a centrifuge bowl of circular cross-section and having an inner surface for spreading centrifugally impelled liquid to be degassed and an annular peripheral trough for retaining centrifugally impelled degassed liquid. The liquid stream is fed into the bowl and the degassed liquid is withdrawn through a tube extending from an exit line outside the housing to an open end of elongate cross-section which is positioned within the trough of the bowl and is immersible in the degassed liquid. The apparatus further provides for measuring the pressure of the exiting degassed liquid, the pressure measurement being used to regulate the flow of liquid into the bowl so as to maintain a substantially constant level of liquid therein. The apparatus also provides for the withdrawal of gas to maintain a sub-atmospheric pressure within the apparatus housing, and for the regulation of the flow of the degassed liquid stream.
