Abstract: An apparatus (10) for dispensing struts (11 and 12) for use by an astronaut in erecting a truss structure in extraterrestrial space comprises a frame to which a platform (16) is attached. The astronaut anchors himself to the platform (16) while erecting the truss structure. Pairs of retainer assemblies for securing opposite ends of struts of different lengths, i.e., the pair of retainer assemblies (22 and 23) for the struts (11), and the pair of retainer assemblies (22' and 23') for the struts (12), are also attached to the frame. One retainer assembly (22 or 22') from each pair is positioned within the astronaut's reach when he is anchored to the platform (16), and the other retainer assembly (23 or 23') from each pair is positioned remote from the astronaut's reach. Each of the remote retainer assemblies (23 and 23') comprises a plurality of spring-loaded receptacles (41) for receiving one end of the corresponding struts (11 or 12).

Abstract: A paper feeding mechanism for selectively advancing paper a predetermined distance past a printing station of an electronic business machine. The paper feeding mechanism is adapted to utilize a supply of fan folded paper, e.g., housed in a disposable cartridge, which may be readily inserted within the paper feeding mechanism to place the electronic business machine in readiness for operation. During the printing cycle, a contact mechanism maintains a portion of the paper in contact with the printing station of the electronic business machine. After the printing occurs, an actuation mechanism is energized to move the contact mechanism away from the printing station to free the paper for advancement. At the same time, the actuation mechanism moves an advancement mechanism to advance the paper a predetermined distance past the printing station of the electronic business machine.
