  • Patent number: 11333980
    Abstract: The overall mechanism for creating the exposure may comprise a table having an outer frame 1110 that holds a transparent (e.g. glass) inner portion 1112. The upper 1120 and lower 1122 linear radiation sources (e.g. banks of LED point sources, optionally mounted inside a reflective housing) are mounted on a gantry system or carriage 1130. The radiation sources are connected to a power source, such as an electrical power cord having sufficient slack to extend the full range of motion of the carriage. Tracks (not shown) disposed on the outer frame portion provide a defined path for the gantry system or carriage to traverse. The carriage may be moved on the tracks by any drive mechanism known in the art (also coupled to the power supply and the controller), including a chain drive, a spindle drive, gear drive, or the like. The drive mechanism for the carriage may comprise one or more components mounted within the carriage, one or more components fixed to the table, or a combination thereof.

  • Publication number: 20210318620
    Abstract: Systems and methods for exposing photopolymer printing plate material located within a target area having first and second dimensions. A light source having LEDs arrayed coextensive with the first dimension moves relative to the second dimension, and emits different light intensities over the target area in at least one of the first dimension or the second dimension. The systems and methods may be used to determine exposure parameters for curing a selected plate by causing different sample units to receive different amounts of total energy exposure, exposure energy per exposure step, or a combination thereof, and visually evaluating each sample unit against a reference plate of the same type and thickness. The sample unit embodying a minimum acceptable total exposure energy and a maximum acceptable exposure energy per exposure step is then identified.

  • Publication number: 20200341378
    Abstract: A method and apparatus to expose photosensitive printing plates with a predetermined radiation density from the main side (top) and a predetermined radiation density from the back side (bottom). The method comprises executing the main exposure with a time delay after the back exposure. The time delay between back exposure and main exposure is optimized to create smaller stable single dot elements on the photosensitive printing plate after processing and smaller single element dot sizes printed on the print substrate. The plate floor may be adjusted by performing a back-side-only exposure prior to executing the combined back and main exposure with the time delay.

  • Publication number: 20080030028
    Abstract: A reach out lock for a sliding door is disclosed. The reach out lock includes keeper having a keeper latch and a locking mechanism having a hook to engage the keeper latch. The reach out lock further includes a mechanism which prevents actuation of the locking mechanism if the locking mechanism is out of alignment with the keeper.

  • Publication number: 20070144072
    Abstract: The present invention provides a window operator for a casement window assembly that has secure and moveable linkage of pivoting parts of the operator. The linkage of the moveable operator parts is provided by a rivet having a rivet head with a plurality of fingers or petals extending radially outward of the center of the rivet, and wherein the petals are formed of thickened rivet material. The rivet head is formed in a conical configuration by the force of bending the rivet head with a conical shaped recess in the forming die, thus providing the method of forming the rivet connection in a smooth and progressive force of deforming the rivet head into a domed shape with the thickened petals extending radially outward and downward due to the conical die surface.

  • Patent number: 6840011
    Abstract: A window having a window panel that slides in a frame and at least one balancer that is secured to the window panel is disclosed. The window is of the tiltable hung type having a vertical operating position in which the balancer slides with the window panel in the frame and a tilted position in which the balancer remains secured to the window panel. The balancer includes an extensible member having a first end operatively coupled to the balancer and a second end operatively coupled to a frame so that the balancer can exert a force on the window panel to assist against the force of gravity when the window panel is in the vertical operating position. A method of constructing a tiltable hung window with a balancer secured to the window panel is also disclosed.
