Abstract: A push button of a keyboard includes a cap movably supported on a base plate by two link members which are pivotally attached to each other and pivotally attached to both the cap and the base plate. A rubber cone is arranged between the cap and the base plate whereby when the cap is depressed, the rubber cone is deformed to trigger a switching circuit for generating a signal associated with the depression of the push button. Pairs of projections are formed on the cap defining a gap between each pair for rotatably accommodating upper pivot pins of the link members. Each projection forms an inclined face opposing each other for guiding and facilitating insertion of the upper pivot pins therein. Tabs are stamped on the base plate and define spaces for rotatably accommodating lower pivot pins of the link members. The tabs form inclined edges for guiding and facilitating insertion of the lower pivot pins into the spaces thereof.

Abstract: A picnic cooking assembly includes a skillet, a cooking pan, and a kettle. The cooking pan nests within the skillet and the kettle nests within the skillet over the cooking pan. The cooking pan, inverted, fits over the skillet to form a food storage container. Moreover, the kettle is formed with a spout covered with a cap which is also securable to the kettle as a handle. Attached to the skillet is a handle which, when the cooking assembly is assembled, fits over and around the kettle, locking the cooking assembly together.

Abstract: A process and an apparatus for laser printing multicolored images are described. The printer includes means for feeding a paper sheet or other recording medium continually with predetermined pauses through a transfer zone and means for moving a recording drum across the surface of said paper sheet in a direction perpendicular to the direction of the paper feed. The recording drum has associated therewith an exposure system and a developer means for applying a latent image and toner, respectively, to said drum. The drum containing toner is rolled across the surface of the paper to effect printing during the periods when the paper feeding means pauses. An erasure means is provided to remove residual toner from the drum after the printing operation. Preferably the exposure system constitutes a plurality of zones, each capable of imaging contiguous areas of the drum and a corresponding plurality of developer zones, each positioned to apply toner to one of the discrete areas of said drum.
