  • Patent number: 4683359
    Abstract: A switch assembly having a pushbutton actuator with graphics backlit by an electroluminescent light source deposited upon a mylar substrate. A separate indicator lamp is provided to be lit when the function selected by the switch is activated. The indicator light is visible through a small window in the pushbutton. In order to prevent light from the indicator lamp from impinging upon the graphics area, a portion of the mylar substrate is opaquely coated to block the light transmission, while the remainder of the mylar substrate is clear to insure proper registration and prevent degradation of the electroluminescent phosphor.

  • Patent number: 3937355
    Abstract: In a trash compactor which includes a ram for compacting waste materials deposited in the compactor, a two-piece, reusable liner is positioned within the compactor to receive the waste material and facilitate removal of the waste material after compaction thereof. Each of the sections is formed of a fairly rigid material, such as polyethylene, and each is provided on its outer surfaces with ribs which serve to both strengthen the liner sections and prevent the liner from sticking to the interior surfaces of the drawer. Each of these sections is constructed of intergrally formed, upstanding sidewalls and a bottom wall with one side wall of each of the sections being just high enough to retain liquids within the liner while permitting their ready assembly and disassembly.
