  • Publication number: 20040226208
    Abstract: Window components are made by a fluid-assist injection molding process to reduce manufacturing costs and provide additional flexibility in the configuration of the window. In addition to the inventive product-by-process, two window configurations, a casement window and a picture window, are taught. The casement window has a frame with installation flanges and the window sash has integral mounting posts for handle hardware. Both the window frame and sash have encapsulated insulative air pockets. An acrylic window pane is taught that mimics a glass block window.

  • Patent number: 4143305
    Abstract: The invention relates to a camera tube arrangement utilizing a so-called H.O.P. (highlight overload protection) or A.C.T. (anti-comet tail) type of camera tube. In order to mitigate the problem of highlights appearing at the top of the picture, in addition to the beam being arranged to discharge overloads in the target area during line flyback, the beam is also arranged to operate in a highlight discharge mode for a predetermined number (for example one) of scanning lines after field flyback but before the end of field system blanking.
