摘要:
An intermodal transportation simulation system comprising a ground transportation simulation node, a rail transportation simulation node, a maritime transportation simulation node and an air transportation simulation node. Each of these simulation nodes are interactive, interconnected and designed to provide a manned multi-sensory, e.g. visual, auditory, olfactory and tactile simulation.
摘要:
Resins and waxes made by reacting selected nucleophiles, including alcohols and/or amines, with an isocyanate are disclosed. The order of addition of the isocyanate and the different nucleophiles can tailor the distribution of di-urethane, mixed urethane/urea, and/or di-urea molecules in the final resin product. The isocyanate-derived resin and wax materials are useful as ingredients as phase change ink carrier compositions used to make phase change ink jet inks.
摘要:
A phase change ink composition is disclosed wherein the ink composition utilizes polymeric dyes in combination with a selected phase change ink carrier composition.
摘要:
An aqueous phase change ink contains a water dispersible sulphonated polyester gloss agent and a selected concentration of hyperthermogelling component that causes the ink to gel when its temperature is increased to its thermo-inversion point or when the concentration of the hyperthermogelling component is increased by evaporation, or substrate absorption, of water from the ink. The ink may be jetted directly onto a heated and/or absorptive substrate or jetted onto a cooler and/or hydrophobic surface before being transferred to the substrate. The thermo-inversion point is preferably about ambient temperature, and the preferred hyperthermogelling component is a nonionic surfactant, such as an ethylene oxide propylene oxide block copolymer surfactant.

A machine-readable serial number is formed on a CD-ROM by using a laser to selectively remove a reflective layer from the CD-ROM. Removal of the reflective layer creates defects in addressable information storage locations on the CD-ROM. The serial number is read by detecting the defects. The serial number is used in a software distribution system in which many different software programs are distributed on a single CD-ROM and an access code based on the desired software program and the serial number of a particular CD-ROM is used to "unlock" the desired program on the particular CD-ROM.

A collapsible, foldable container with reduced deflection and increased strength and convenience is provided. A door can be provided in the lower portion in one or more of the sidewalls, opening upward and outward without unduly loading the door hinges. A latch is provided to hold the door in the open configuration engageable by slamming open and disengaging by jerking close. In one embodiment, the base of the container includes a plate having ribbing extending upwardly therefrom. When a smooth-bottomed surface is desired, a plate may be installed on top of the upwardly extending ribbing. Ribbing on the bottom surface and/or sidewall surfaces can include close-loop or circular ribs with integral ribbing extending radially therefrom. Preferably, containers are configured so that they can be stacked, one upon the other, either with or without a top or lid. Preferably, the lid, when provided, avoids pooling of liquids such as rainwater by having a domed-shape and by providing channels in a peripheral ridge. Sagging in the components of the container can be at least partially avoided by providing ribbing in regions extending from the center of the bottom of the container towards peripheral portions, preferably corners.
摘要:
An apparatus is disclosed for preparing a quantity of individual treated fibers from one or more fiber mats. The apparatus comprises a fiber treatment zone, and a conveyor for conveying each mat through the fiber treatment zone. In the treatment zone each mat is impregnated by an applicator with a treatment material, such as a crosslinking substance, and conveyed directly to an attrition device. The attrition device fiberizes the mats to form a fiber output having a low nit level, such as no more than about three, and a dryer both dries the fiber output and cures the crosslinking substance. The fiberizer is configured to minimize the accumulation of fiber at locations therein. Fiber is transported from the attrition device to the dryer at a high velocity under reduced pressure to promote drying. A heated retention bin is provided after drying to increase curing time in the system. A thermobonding agent may be added to the dried and cured fibers to enhance the wet strength of webs made from the fiber.

An ultrasonic diagnostic imaging system is provided which scans an image region to receive a plurality of spatially arranged lines of ultrasonic image information signals. These ultrasonic line information signals are used in an interpolater to interpolate one or more lines which are spatially interlineated between each pair of spatially adjoining received lines. These interpolated lines are produced using either the received RF or demodulated IF ultrasonic image information signals. The interpolated lines are produced prior to scan conversion, and preferably prior to nonlinear processing such as detection or log compression to reduce spatial aliasing artifacts. In one preferred embodiment the interpolater comprises a transversal filter of four taps which is responsive to received line information signals from a common range or depth. In a second embodiment the interpolater is adaptively responsive to motion to select samples for interpolation which would be spatially at the same range in the absence of motional effects.
摘要:
A fiberizer is described having a rotor to which plural hammers are mounted for fiberizing a sheet of fibers delivered to the rotor as the rotor is rotated. A feed mechanism utilizing a pair of seal rollers, at least one of which is driven, is configured for effective delivery of both wet or dry sheets to the fiberizer. The hammers are configured to minimize dead spaces within the fiberizer. In addition, air flow is directed through the fiberizer to minimize accumulations of fibers therein. Furthermore, an optional liquid flushing mechanism is provided for periodically cleaning the fiberizer during use.
