Abstract: A self inking stamp is provided for use in making an image on paper. The stamp comprises a body having a base including portions lying in a plane for engagement with a flat piece of paper, and a marker having a self inking indicia. The maker is movable relative to the base generally at right angles to the aforementioned plane, and a coupling is provided attaching the marker to the base at a location spaced from the marker generally parallel to the plane. The coupling permits movement of the marker to a stored position inside the body and spaced from the plane, and an inking position with the marker in engagement with the paper.

Abstract: A structur for containing incorporation documents and a corporate seal embosser the structure including a top element of a selected width defining the top and an angled display wall for carrying a sample of a corporate seal to identify the contents of the structure, a fixed side wall dependent from the top structure and of a substantially selected width, a fixed side dependent from both the top and the angled display wall rectangular but for an angled edge shaped to meet the display wall a bottom hinged to the fixed side and of substantially the selected width, a lid hinged to the bottom for movement with the bottom into position in engagement with the fixed side wall and the top element, the lid being of a similar shape to that of the fixed side, a collapsable side wall hinged to the fixed side and of substantially the selected width for movement to meet the lid and the top element when the structure is closed, wall closure means coupled to the collapsable side wall and to the top element to releasably retai

Abstract: A fuel control for a gas turbine engine is operable in a training mode in addition to the conventional automatic and manual back-up modes. In the training mode the manual mode is simulated, with signals commensurate with operator action being delivered to the fuel metering valve actuator, while protection against exceeding the safe operating limits of the engine is provided.
