    • A method and device for raised letter or graphics printing, by means of a sprayed wet ink deposition on a print substrate. Subsequent dispensed thermographic powder thereon, with adherence of the powder only to the wet ink and heating thereafter, to a fixing temperature of the powder, results in the raised lettering or graphics. A standard portable ink jet printer (20) of the bubble jet type, controlled, with graphics software control, by a personal computer, provides the requisite non-contacting ink deposition. The dispensing cartridge (s) (23) of the ink jet printer is (are) provided with non-contacting-drying ink formulations for the portion of graphics or printing which is to be in raised form. A thermographic powder dispenser (33) and heating member (35) is connected to the output of the ink jet printer (20) for completion of the raised printing process. The device is particularly useful in providing non-impact formed braille lettering.
    • 一种用于凸字母或图形印刷的方法和装置,其通过在印刷基底上的喷墨湿墨沉积。 随后分配的热成像粉末,其中仅将粉末粘附到湿墨水并随后加热到粉末的定影温度,导致凸起的字体或图形。 通过个人计算机控制的具有图形软件控制的气泡喷射型的标准便携式喷墨打印机(20)提供必要的非接触墨水沉积。 喷墨打印机的分配盒(23)(其)设置有用于图形或印刷部分的非接触干燥油墨配方,其将是凸起形式。 热成像粉末分配器(33)和加热构件(35)连接到喷墨打印机(20)的输出端,以完成升高的印刷过程。 该设备在提供非冲击形式的盲文字体中特别有用。

    • A method and device for raised letter or graphics printing, by means of a sprayed wet ink deposition on a print substrate. Subsequent dispensed thermographic powder thereon, with adherence of the powder only to the wet ink and heating thereafter, to a fixing temperature of the powder, results in the raised lettering or graphics. A standard portable ink jet printer of the bubble jet type, controlled, with graphics software control, by a personal computer, provides the requisite non-contacting ink deposition. The dispensing cartridge(s) of the ink jet printer is (are) provided with non-contact-drying ink formulations (with two or more separate colors, if desired) for the portion of graphics or printing which is to be in raised form. A thermographic powder dispenser and heating member is connected to the output of the ink jet printer, or integrated therewith for completion of the raised printing process. In operation, the non-contact drying ink is dispensed from the ink jet printer onto a print substrate, with program controlled bit-mapped instructions of graphics and text, via the personal computer. Simultaneous inking of the substrate with separate colored non-drying inks permits single pass multi-colored raised printing. Raised and non-raised printing is also possible by use of separately dispensed drying and non-drying inks. The device is particularly useful in providing non-impact formed braille lettering; and graphics, with full or partial raised portions and separated color segments.

    • A thermodynamic constant volume vapor compression heat pump system including a method and apparatus wehrein a closed fluid loop having first, intermediate and second treatment stations, is employed. A liquid refrigerant fluid under low pumping pressure is introduced to a first treatment station (100) following initial expansion, accelerating propulsion, and atomization thereof, precedent to evaporation of the refrigerant fluid through a divisive containment of the accelerated refrigerant fluid. A counterflowing of a warm contained fluid under treatment occurs in heat-exchange conduction relation to the refrigerant fluid, proximal the vaporizing refrigerant of the laminar flow thereof is disturbed at no greater than one atmosphere; thereafter the vaporized refrigerant fluid is compressed at an intermediate station (200) while diverting no greater a measure than 10% thereof to sequentially augment propulsion of oncoming liquid refrigerant through said first station; thence, the remaining bulk of compressed refrigerant fluid is passed under high pressure through a second treatment station (300) wherein the compressed refrigerant vapor is sequentially condensed by reverse-evaporation, the compressed refrigerant fluid being subjected at said second station to external conductive influence of a coolant fluid, said respective coolang fluids being divisively confined in counterflow conduction relation, and the steps aforesaid are repeated seriatim, cyclically.
