  • Patent number: 9606003
    Abstract: Method and apparatus for measuring temperature of a measured area of a surface without contacting the surface. The thermometer apparatus has an optical system which generates a correlative image of an infrared energy detector sensitive area at an image distance from the thermometer. A limiting aperture, having a size and a shape corresponding to those of the generated image, is between a mirror and the generated image. The measured area of the surface is between the generated image and the thermometer in use. With such a configuration, little infrared energy that does not originate from the measured area strikes the detector. Consequently, the energy reaching the detector is limited such that the size of the measured area remains constant, regardless of changes in the thermometer's field of view attributable to differences in the distance between the surface and the thermometer. A scan-and-integrate mode for practicing the invention is disclosed.

In a primary separation step, raw grains containing the lightweight grains are whirled upward with primary air along the inner wall of the cylindrical section for allowing raw grains and part of the lightweight grains to stay in a certain flow area by frictional resistance with respect to the wall surface generated by whirl, and to drop into the conical section on the downside by their own weight. In a secondary separation step, secondary air is blown toward the raw grains dropping into the conical section in the primary separation step to blow the contained lightweight substances upward to the space in the cylindrical section. In a discharging step, raw grains with the lightweight grains removed are taken out from the conical section. A tertiary separation step for blowing the tertiary air may be added.

  • Patent number: 5887725
    Abstract: A raw material is dispersed around a rotating separator main body having a plurality of classifying blades annularly arranged on the main body and is exposed on a rising flow of classifying air so as to sift off crude powder which cannot be entrained on the flow of the classifying air. The remaining raw material entrained on the classifying air is peripherally introduced into the separator main body for classification into fine and crude powders, the fine power being the powder which is allowed to pass through the classifying blades while the crude powder is the powder which is not allowed to pass. A dispersion plate is arranged between the separator main body and a raw material inlet above the separator main body to receive and disperse the raw material from the inlet. The dispersion plate is rotatable at number of revolutions different from that of the separator main body.

  • Patent number: 5557386
    Abstract: A toner recovering device for an electrophotographic apparatus, which includes: a dust collector connected to a device for cleaning untransferred toner remaining on a photosensitive body; a toner recovering filter having an inlet port for introducing an air-toner mixture from the dust collector side and an exhaust port for filtering the air-toner mixture and discharging the air from which the toner has been removed; a filter mounting section for mounting the toner recovering filter; a joint mechanism having a joint and a hose member, one end of the hose member capable of being connected to the dust collector and other end thereof being joint, the joint being disposed at the inlet port, the joint mechanism being arranged in the filter mounting section in such a manner as to be opened and closed; a detector for sensing that the toner recovering filter has been mounted or not onto the filter mounting section; and a pulling member for coupling the inlet port of the toner recovering filter to the joint in synchron

  • Patent number: 5511668
    Abstract: A pneumatic sifter includes a feeder for supplying sift material, optionally with sifting air, to a rotationally symmetrical sifting chamber which surrounds a centrally disposed air outlet chamber, and a coarse particle discharge. In order to keep the flow resistance low as air enters into the air outlet chamber, guide vanes are provided in the air outlet chamber, which are spaced from each other at uniform angular distances and extend approximately over the axial extension of the sifting chamber.

  • Patent number: 5452804
    Abstract: A machine for sorting recyclable matter includes a trommel for conducting and screening an input flow of recyclable matter and a magnetic mechanism coupled to the trommel for extracting magnetic material from the input flow while the trommel rotates. The input flow is dropped vertically from the trommel into a positive-pressure air separator which separates the flow into a first material stream including lightweight articles and a second material stream including relatively heavy articles. The heavy articles of the second material stream drop downwardly in the air separator. Padded baffles are provided in the air separator for reducing the downward velocity of the second material stream, which substantially lowers breakage of glass articles.

  • Patent number: 5451318
    Abstract: A filtration system for water or other selected liquids that includes an ozone mixing station, a primary solids and gas separator and, if desired, a second vortex particle separator and filter system. The ozone mixing station includes a high efficiency ozone generator and a channel arrangement, such as a spiral tubular treatment coil, through which the ozone/liquid mixture passes to assure thorough mixing and provide time for effective treatment. The primary solids separator includes an offset inlet jet through which the liquid from the ozone treatment station is injected into a first circular chamber. The resulting rotating liquid vortex moves to a narrowed co-axial second circular chamber to cause heavy particles to concentrate at the outer perimeter then to a coaxial larger third circular chamber. The liquid exits through an annular outlet located around the chamber axis to prevent buoyant particles in the axial region and heavy particles at the outer periphery from passing out with the liquid.

  • Patent number: 5366095
    Abstract: An air classification system comprises of dual cylindrical chambers mechanically separated, to allow a zone of atmospheric air in between. A primary classification chamber situated vertically below a concentric secondary classification chamber. A rotating parallel blade turbine is situated within the lower primary chamber in order to effect centrifugal particle classification upon a feed material intimately mixed in an air stream. A tubular rotary discharge connected to the turbine which passes through the zone of atmospheric air separating the dual chambers, and extends into the upper secondary chamber which exists to collect and discharge the classified product from the system. A classifier of this design is capable of separating ultra fine particles without stray amounts of oversize with extremely high fine product yields.

  • Patent number: 5341935
    Abstract: A method of separating solid waste materials, in the form of dried particles of substantially uniform size, into constituent materials on the basis of density, with primary stage processing utilizing a series of fluidized bed and cyclonic separator assemblies to separate materials on the basis of density, followed by secondary stage processing utilizing combinations of vibratory conveyors, melt separation assemblies, and the like, is provided by the present invention. As the waste materials move through the separator assemblies the initial stream is further refined into a plurality of streams of increasingly specific densities as a result of air flow separation of lighter particles from heavier particles in each assembly. Further refined separation may be achieved through the use of vibratory conveyors, melt separation, and the like.
