Patent BR-9912720-A (BR)
Inventor: TESSIER DAVID FLORIAN
IPC: B01D61/48
Filed: 1999-06-25
Abstract: A method and apparatus for inhibiting scaling in an electrodeionization system or in a combined reverse osmosis/electrodeionization system for water treatment and, more particularly, for increasing tolerance to hardness in the feed water to an electrodeionization unit to inhibit precipitation of metal cations contained in the feed water and for increasing efficiency of the electrodeionization system. Water to be purified is passed through a electrodeionization unit in which a concentrate stream recycling through concentrating compartments and anode and cathode compartments contains effective amounts of an antiscalant to inhibit precipitation of scale. One or more preliminary reverse osmosis units in series with the electrodeionization unit preferably receives a portion of the antiscalants in the concentrate stream. The antiscalant in the water fed to the reverse osmosis unit can be supplemented and adjusted. Electrolyte can be provided to the concentrate stream of the electrodeionization unit from products of the reverse osmosis.

Title: Heat setting polymer filaments by h f heating
Inventor: PETER KNOBLOCH
IPC: D06M10/00
Filed: 1967-08-07
Abstract: A process for continuously heating, drying and heat-setting wet tows of filaments comprising synthetic high molecular weight polymers, in which the tows of filaments are passed continuously through a high frequency electric field. The intensity of the field used is preferably 0.2-5 Kv/cm. and particularly 1-1.5 Kv/cm. with a frequency 5-25 Mc. The tows of filaments are passed continuously between plates generating such a field. The H.F. power of the generator is somewhat greater than that calculated from the specific heat of the fibres and the water to be vapourized. The process enables heating, drying and heat-setting bundles of wet fibres a few cm. thick to take place without expansion and after crimping. Higher dye absorptions and a closer tow can be achieved.

Title: Timing control circuit of AC type plasma display panel system
Inventor: KIM SE-YONG
IPC: G09G3/28
Filed: 1998-12-29
Abstract: Disclosed is a timing circuit which produces control signals by which a data interfacing section can simultaneously implement input and output operations of a video data from a frame memory to an address electrode driving section, respectively. A first pulse signal (110c) whose pulse duration corresponds to a whole horizontal line time, a second pulse signal (120c) which is identical to a delayed first pulse signal by one horizontal line time and a third pulse signal (130c) whose pulse duration is one horizontal line time longer than that of the first pulse signal are produced by using a system clock signal of a 2 MHz frequency. During the pulse duration of the first and second pulse signals (110c, 120c), first and second clock signals (110e, 120e) which contains 480 numbers of clock pulses with a period of one horizontal line time are produced by counting another system clock signal of a 25 MHz frequency. During the pulse duration of the third pulse signal (130c), a third clock signal (130e) which contains 481 numbers of clock pulses with the period of one horizontal line time is produced by counting the system clock signal of the 25 MHz frequency. The first, second and third clock signals (110e, 120e, 130e) are provided to the frame memory, the address electrode driving section and the data interfacing section, respectively. By means of operations of these three clock signals, the data interfacing section can simultaneously implement the input operation of the video data of one horizontal line from the frame memory and the output operation of the video data to the address electrode driving section.
