A magnetic auger in the form of a cylinder having one or more magnetic helices in the surface thereof is disclosed for transporting ferromagnetic particles such as toner particles used in magnetography.
摘要:
An elongated pile article having a support strand for attachment to a plurality of yarn bundles, the yarn bundles including a dense portion with the filaments bonded to each other and bonded to the support strand, pile surface structure comprised of a plurality of elongated pile articles placed one next to the other, and a method and apparatus for making the elongated pile article.
摘要:
The method of taking a blood sample utilizes a cannula having a penetrating point at its distal end and an elongate lateral opening through the cannula wall on the side opposite the point. The steps of the method include sealing the lateral opening with a slidable sleeve which has an outwardly-extending base, sealing the base against the patient's skin, aligning the cannula with a blood vessel and inserting the cannula to a depth sufficient to pierce the blood vessel, and applying a slight vacuum on the cannula to withdraw blood therethrough.
摘要:
Magnetic printing apparatus for forming on a substrate a colored print of an original colored design, said apparatus comprising a ferromagnetic printing means which is imposed on an electrically conductive support; means for forming on the ferromagnetic printing means a magnetic image of a photocolor-separated film positive of the original colored design; means for developing the magnetic image on the ferromagnetic printing means with a toner comprising a ferromagnetic component, a dye and a resin; means for transferring the developed image to the substrate, and means for neutralizing static electricity on said toner. Optionally, the apparatus may include: means for transferring the developed image from one substrate to another; means for fixing said dye on and/or in an ultimate substrate; and/or means for removing said ferromagnetic component and said resin.
摘要:
A method of drilling and blasting a field is disclosed. By use of a certain combination of blasting agents, it is possible to expand the bore hole pattern by 30 to 50%, thereby decreasing the number of bore holes per unit of area to be blasted.
摘要:
A process for reproducing graphic information wherein a magnetic image is formed in a premagnetized layer of acicular chromium dioxide by heating the chromium dioxide selectively to above its Curie point. Uncharged ferromagnetic toner particles are then applied uniformly to the chromium dioxide layer, but adhere only in the magnetized areas. The toner particles are then transferred electrostatically to a substrate.
摘要:
Transparent sheet for use with ink jet printers and pen plotters which utilize hydrophilic solvent-based inks. The sheet comprises a transparent backing bearing on at least one major surface thereof a transparent coating formed of a blend of at least one hydrophilic polymer containing a carbonylamido functional group and at least one hydrophobic polymer substantially free of acidic functional groups, hydroxyl groups, >NH groups and --NH.sub.2 groups.
