Publication number: 20130316152Abstract: There is herein described a method and apparatus for photoimaging. More particularly, there is described a method and apparatus for photoimaging a substrate (e.g. a web) covered with a wet curable photopolymer wherein a rotatable phototool is pressed and rotated against the substrate to create an imaged substrate which is used to form images suitable for forming electrical circuits such as for printed circuit boards (PCBs), flat panel displays and flexible circuits. There is also described a method and apparatus for directly photoimaging a substrate covered with a wet curable photopolymer, wherein the photoimaged substrate is used to form images such as electrical circuits and a method and apparatus for exposing at least part of a solder mask on a printed circuit board (PCB) using a wet curable photopolymer wherein an imaging process may thereafter occur on the area above the solder mask.Type: ApplicationFiled: November 11, 2011Publication date: November 28, 2013Applicant: RAINBOW TECHNOLOGY SYSTEMS LTDInventors: Charles Jonathan Kennett, John Cunningham, Robert Gibson

Patent number: 8157715Abstract: A fluid supply assembly for a shaft mounted device, such as an oscillating roller, is disclosed having a fluid powered apparatus comprising a shaft comprising a first fluid passageway extending through a portion of the shaft and exiting at an exit point on the shaft wall; a connector arranged on the device having a bore for receiving the shaft comprising a first seal spaced apart from a second seal within the bore along an axis parallel to the shaft, the first seal, second seal, the bore and the shaft wall defining a fluid annular chamber, and a second fluid passageway leading from the fluid annular chamber to the fluid powered apparatus wherein, in use, the exit point on the shaft wall remains between the first and second seals. The fluid supply assembly allows quick release application of fluid powered rotating devices.Type: GrantFiled: June 27, 2008Date of Patent: April 17, 2012Assignee: ITW CS (UK) LimitedInventors: Sheila Hamilton, Charles Jonathan Kennett

Patent number: 7415747Abstract: The invention relates to surface cleaning apparatus for removing contamination from sheet materials such as phototools and liquid crystal display (LCD) screens. The apparatus comprises a base unit having opposing walls for supporting a removable roller cartridge containing at least one cleaning roller and one adhesive roller. Progressive insertion of the roller cartridge into the base unit causes a camming mechanism provided on the base unit and the roller cartridge to interact so as to move the cleaning and adhesive rollers from a non-operatinig position in which the rollers are separated into an operating position in which the adhesive roller is brought into abutment with the cleaning roller. The apparatus is held in the operating position by a latching mechanism, for example, an electromagnet which may be selectively activated and deactivated simultaneously with activation and deactivation of a driving motor.Type: GrantFiled: July 28, 2004Date of Patent: August 26, 2008Assignee: Teknek Holdings LimitedInventors: Shiela Hamilton, Charles Jonathan Kennett
