Abstract: The transport, that carries the material to be scanned to and from scanning position, is held against its support by suction. After the transport has been moved into scanning position the suction is applied progressively starting at one end of the transport and continuing to the other end. A squeegee roller presses the transport against its support. This roller passes over the portion of the transport to which suction has just been applied, but prior to the time that suction is applied to the next section of the transport.

Abstract: A simulated flame torch which gives a student the opportunity to light a simulated furnace using the simulated torch without actually starting a fire and incurring a potential fire hazard. The apparatus comprises a hollow shaft that is attached to a handle; a plurality of light pipes connected to the shaft near its bottom; a source of electric power contained within the shaft; a plurality of electric lamps coupled to the power source; and means for turning the lamps on so that light will be transmitted through the light pipes simulating a flame when the light moves through the air. Thus, the device can be used to teach a student the proper procedure for handling a lighted torch.
