The ink contains a coloring material and polymer fine particles which are a mixture of a crystalline polymer and an amorphous polymer.

Abstract: A system for deploying and selectively inflating a thoracic aortic balloon at a desired location within the thoracic aorta for resuscitative aortic occlusion, inferior to the left subclavian artery, without the aid of fluoroscopy is described. Using CT imaging data, a distance between readily identifiable and consistently located external landmarks of torso extent is measured. Next, using the same data, a second distance from the femoral artery to a desired aortic occlusion location inferior to the left subclavian artery is determined. A correlation between the external measure of torso extent and the desired intra-arterial (i.e. endovascular) distance within the torso is made. Using a nomogram, a calibrated endovascular resuscitative thoracic aortic occlusion system can be positioned to this desired location on any injured individual with end-stage shock and impending cardiovascular collapse or death without the aid of fluoroscopy for delivery or balloon inflation.

Erasure is caused by moving a magnetic field which enters and exits the media at a finite angle but stays parallel to the media in some region. A magnetic stencil comprising regions of dissimilar permeabilities is described. The magnetic stencil can be used in conjunction with the erasure means to simultaneously create alternating fields parallel and normal to the media thereby permitting information to be written over any previously recorded information without requiring a seperate erasure step.

Abstract: A rewritable recording/display apparatus using a rewritable recording medium in which color development reaction occurs by thermal energy at a predetermined temperature, and in which a color extinguishing reaction occurs by thermal energy at a temperature lower than the color development temperature, and which is capable of repeatingly performing recording and erasing of images. The apparatus also has a color developing heating device for recording an image on the rewritable recording medium by heating the rewritable recording medium, and an erasing heating device for erasing the image after the image has been recorded.

Abstract: The technology encompassed by the practice of this invention includes apparatus for ink jet printing under the control of electronic circuitry and ink jet printing under the control of an operator, for example, a typewriter. Broadly, the technology presented in accordance with the principles of this invention utilizes an ink eradicator which removes indicia of the ink by chemical reaction.

Specifically, practice of this invention is contemplated with means that applies the eradicator fluid over the location on a surface where printing has occurred by ink jet droplets as well as over an entire area thereon within which there is ink jet printing for which a change is to be achieved.

Abstract: This disclosure obtains printing and displaying of information stored as a pattern of orifices in a colored liquid film established on the interstices of a screen-mesh member. A laser beam is used to effect removal of the film at each selected interstice either by puncturing the film thereat or vaporizing a portion thereof so that reactive surface tension force displaces the remainder of the film. The screen is moved in coordination with the writing thereon of the information pattern so that the area upon which the information is established may be presented sequentially to a displaying station and to a printing station. At the displaying station, light is either transmitted through the orifices established in the colored liquid film or is reflected from the film left in the unwritten interstices onto a display screen as a pattern of information either as a positive or a negative image of the actual information content established in the screen-mesh.
