Patent number: 11123752Abstract: An example of a species collection system includes a plurality of spaced-apart electrically conductive collectors and a plurality of emitter electrodes. In some embodiments, at least one emitter electrode is disposed between adjacent ones of the collectors. In some embodiments, the at least one emitter electrode extends beyond the collectors (e.g., in at least one dimension). Collectors may be aligned to a direction of gas flow from an outlet (e.g., of a cooling tower) to facilitate collection while minimizing interference with the gas flow. Different emitter electrodes may be maintained at different voltages. In some embodiments, collectors are attached to a collector frame and emitter electrodes are attached to emitter frame(s) that are electrically insulated from the collector frame. Collectors may span a gas outlet (e.g., of a cooling tower) and emitter frame(s) may be positioned outside of the collectors (e.g., and outside of a periphery of the gas outlet).Type: GrantFiled: June 30, 2020Date of Patent: September 21, 2021Assignee: Infinite Cooling Inc.Inventors: Maher Damak, Karim Khalil, Carl Frederik Brasz, Kripa Varanasi

Patent number: 5366540Abstract: A mechanism for rapping the electrodes of an electrostatic precipitator for the purpose of dislodging dust deposited on the electrodes is disclosed. The rapping mechanism incorporates a pair of impact beams (1, 1') between which collecting electrodes are suspended. The impact beams are so arranged that the beams slide on the upward-facing edges of a pair of support carriers (2, 2') secured to the precipitator housing. A drop hammer (7) rotatable about a horizontal shaft raps an anvil (6) secured to the impact beam pair (1, 1'), thereby causing a horizontal vibration of the impact beam pair (1, 1') without imparting any impact energy to the precipitator housing. A pair of springs (12) secured to the precipitator housing, one at each end of the impact beam pair, act against the horizontal movement of the impact beam pair and restore the impact beam pair to its original position.Type: GrantFiled: August 26, 1993Date of Patent: November 22, 1994Assignee: FLS MILJO A/SInventor: Erik M. Bojsen

Screens suitable for use in photo-engraving and photo-lithographic processes and in color television
Patent number: 4114982Abstract: This invention is concerned with light transmitting screens which can be used in printing of half-tone illustrations such as photographs and in color television. The screen is formed on one face with a plurality of projections or depressions which so adjoin one another that the face is free of interstices, light incident on the contoured surface so formed being refracted as it passes through the screen to break up the image being transmitted into a pattern of dots. For use in color television, the projections or depressions are defined as triangular pyramids whose surfaces are subtended from their bases at different angles to be in sympathy with the wavelengths of the different colors being transmitted.Type: GrantFiled: April 15, 1976Date of Patent: September 19, 1978Inventor: Raymond Buckley -

Patent number: 4012257Abstract: A method of producing gravure printing surfaces is disclosed. The method utilizes a separately produced screened negative made on orthochromatic film and a continuous tone negative. Both negatives are superimposed to produce a positive with variable size dots and variable tone densities which are then utilized to expose the carbon tissue resist used to etch the printing surface. Alternatively, the negatives are utilized to produce corresponding positives each of which is used to expose the carbon tissue.Type: GrantFiled: February 13, 1976Date of Patent: March 15, 1977Inventor: Frank T.
