    摘要: An expandable piston rotary engine includes a core having a substantially circular periphery and central axis, and a rotor/flywheel mounted concentrically for rotation relative to the core. The core defines a plurality of cylinders spaced symmetrically about, and open at, the periphery of the core. Each cylinder contains a radially expandable, substantially cylindrical piston formed of a relatively thin web of material, such as sapphire or amorphous steel. The piston web material is coiled about its associated cylinder axis, and defines an internal combustion chamber whose diameter, and volume, vary in response to a relative coiling and uncoiling of the web in its cylinder. The inner surface of the rotor/flywheel defines with the periphery of the core, the cylinders and the outer surfaces of the pistons a closed space for a hydraulic fluid. Intake and exhaust valves and fuel igniters are associated with each of the cylinders. The core and other engine components are formed of lightweight ceramic materials capable of withstanding very high operating temperatures. By driving the rotor shaft relative to the core, and changing the valving to the piston chambers, the engine may be converted for use as a compressor or fluid pump.

    摘要: A printing ink comprises a clear, transparent, polymeric carrier material and uniform, colloidal size charged color particles evenly dispersed therein. The carrier and the particles are adhesively bonded to one another so as to form a matrix which can collectively respond to an externally imposed electrostatic field to promote co-movement of a "bite" of ink to an imaging medium without change of the bulk particle/carrier ratio. During the printing process, the ink is melted and exposed to electrostatically charged latent image areas on a heated image cylinder, resulting in the transfer of the ink thereto in proportion to the electrostatic field strength. The ink exhibits a relatively sharp liquid-to-solid transition, thereby enabling rapid ink solidification and complete transfer from the imaging medium to the relatively cool printing substrate. Also disclosed is a printing method and apparatus that facilitate continuous, variable and on-demand color printing in conjunction with the ink. Use of essentially monodispersed, color-coated, colloidal size, spherical particles in the ink results in excellent color purity and chromaticity range.

    摘要: A method of delivering particles into a cellular specimen such that there is minimal disruption or damage to the specimen. In accordance with the method, a monodispersion of tiny acicular magnetizable particles is formed and that dispersion is placed in contact with the specimen. Then the dispersed particles are subjected to a nonuniform converging magnetic field having an axis of convergence which intersects a selected target area in the specimen and whose field lines converge to a focal point proximal to the specimen. Under the influence of the field, the particles align themselves with the field lines and travel into the specimen toward the focal point beyond the specimen. The method may be used to deliver particles at the cellular, microbial, tissue and organ levels and the agents that are deliverable by the method run the gamut from radiation, heat, DNA and diverse biological and chemical materials. Apparatus for practicing the method at these different levels are also disclosed.

    摘要: An optoelectronic signal recording and storage medium including a base layer, a conductive layer, a photoconductive layer and storage layer has a coherent crystal morphology throughout, even though the chemical and electrical properties of its layers are by choice dramatically different. The base layer is preferably made of monocrystalline sapphire grown in a manner as to allow the growth of the other layers directly on a surface of the base layer without the need to grind and polish that surface, thereby minimizing internal defects in the medium. The monocrystalline base layer also allows the acceptance of exeptionally uniformly distributed charges over wide areas of the medium, thereby enabling the medium to locally record and store minutely differing optoelectronic signals on a background of minimal noise, thus facilitating low light level electronic or optical recording and long term storage of signals and minimal energy readout of those stored signals. The medium base layer can be thin enough to be flexible and transparent and yet to have great strength to provide a firm foundation for the other medium layers. A method of making the medium is also disclosed.

    摘要: Apparatus and a method are disclosed that can be selectively operated with equal advantage to strip sheet material from either the top or the bottom of a stack. A translatable member having a generally planar surface formed of an electrically insulative material is disposed proximate to either the top or bottom of a stack of sheet material. A pair of electrodes in the form of an electronic grid is secured to the planar surface. A DC voltage is applied to the electrodes selectively to effect a highly intense electric field only close to the surface of the member. The intensity of the electric field can be varied in predetermined relation to the applied DC voltage so as to determine the number of sheets simultaneously removed from the stack. The electric field exerts an attractive force only on the end-most sheet or sheets of the stack so that said end-most sheet or sheets only will be stripped from the stack.

    摘要: A method of electrophotographic color reproduction by forming sequentially superimposed toner images of each color successively on the photoconductive surface of an electrophotographic recording member. The photoconductive surface is charged uniformly by a corona generator to a predetermined charge level. The charged surface is exposed to a first color radiation pattern from a source thereof to form a latent electrostatic charge image on said surface. The resulting latent charge image is toned with one color toner to produce a first toner image. The resulting toner image is dried. Thereafter, a charge is applied uniformly to the same photoconductive surface including those portions thereof carrying the dried first toner image in a manner so that the generated charged ions effectively tunnel through the dry adjacent toner particles defining first toner image to reach the photoconductive surface. The resulting charge potential is uniformly distributed over the entire photoconductor surface, including the toned and untoned areas thereof.Thereafter, the entire charged surface is exposed to a second radiation color pattern from a source thereof, the radiation penetrating the first toner image to produce a second latent electrostatic charge image on said overall surface. Toning is effected with a second color toner to define a second toned color toner image superimposed in proper registry. The second toner image is dried and the aforementioned steps are repeated until the desired number of color toner images superimposed one upon the other are completed to form a desired composite color toner image. The complete image is transferred to an image receptor in a single transfer step to achieve the desired print reproduction.

    摘要: Documents are encoded with at least one thin, transparent coating, normally invisible, but having a readily detectable physical characteristic such as, electrical conductivity, electrical impedance, electrical capacitance, electroluminescence. Each document consists of a substrate on which is applied (1) at least one of the thin coatings, and (2) conventional printing, preferably intaglio. The thin coating may be applied before or after the printing. The coating includes particles driven into the surface to a substantial depth. The uncoated substrate is free of the detectable physical characteristic. The coating is confined to a limited area of the substrate surface and itself constitutes a code or is laid down in a pattern for identification. A second coating can be applied so that all areas of the surface have the same appearance to mask visual detection of the first coating. The first coating can be of such a nature as to defeat electrostatic copying, particular, color copying, by effecting a discernible difference between the original and the copy. Each coded coating is detectable by a machine which is capable of quickly distinguishing a genuine document from a counterfeit document.
