TL;DR: In this paper, a self-contained gas powered endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue, which includes an anvil member and a surgical fastener cartridge member mounted to the distal end of an elongated endoscopic portion.
Abstract: A self contained gas powered endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes an anvil member and a surgical fastener cartridge member mounted to the distal end of an elongated endoscopic portion. A tubular collar of the endoscopic portion moves distally to engage the anvil member and bias the anvil member and the cartridge member into cooperative alignment, thereby clamping body tissue to be fastened between the anvil member and the cartridge member. A self contained pneumatic system is disposed in the surgical apparatus and is actuable to eject and/or form the surgical fasteners in the clamped body tissue. The apparatus further comprises a locking mechanism for preventing approximation of the anvil member and the cartridge. In one embodiment, a clamping interlock is shown which prevents approximation of the jaws when the jaws are either misaligned or improperly inserted into the instrument. In a second embodiment, a clamping interlock is shown which directly engages the tubular collar preventing approximation of the jaws when a cartridge member is not fully inserted. In a third embodiment, a clamping interlock is shown which directly engages the tubular collar when an unfired cartridge is not present or properly inserted into the instrument.

TL;DR: Pfeffer et al. as discussed by the authors investigated the effect of alternate sources of information on the relationship between interlocks and corporate acquisitions and found that most alternate sources (e.g., CEO membership in the Business Roundtable) reduce the impact of the interlock, but one source (business press coverage) increases it.
Abstract: We would like to thank Jeff Pfeffer, Joel Podolny, and seminar participants at Stanford University, UCLA, and the Johnson School at Cornell for helpful comments on earlier versions of this paper. The purpose of this study was to investigate when director interlocks affect corporate behavior, and how much influence they exert, by studying the conditions under which their influence varies. Existing theory supports the view that interlocks provide information, which affects firms' adoption of strategies and structures. If interlocks provide information, their influence should diminish to the extent that alternate sources of information are available. We measured the effect of alternate sources of information on the relationship between interlocks and corporate acquisitions. Results show that most alternate sources (e.g., CEO membership in the Business Roundtable) reduce the impact of the interlock, but one source (business press coverage) increases it. Also, information from similar interlock partners is more influential than information from dissimilar interlock partners. Our findings suggest a theory of interorganizational information: the substitutability and complementarity of multiple information sources affect their influence. The implications of our study for interlock and information theories are discussed.'

TL;DR: In this paper, a surgical fastener applying apparatus is provided with a shipping interlock to prevent premature actuation of the apparatus by the jostling and vibrations which normally occur during shipment of the device from the supplier to the user.
Abstract: A surgical fastener applying apparatus is provided with a shipping interlock to prevent premature actuation of the apparatus by the jostling and vibrations which normally occur during shipment of the apparatus from the supplier to the user. The shipping interlock includes a projection extending from the cam bar retainer and initially disposed through an elongated aperture in an interlock plate having an open distal end. The aperture has a narrow neck portion through which the projection can pass only with sufficient force applied to the cam bar retainer. The shipping interlock is adapted to permit passage of the projecting member when the force exceeds the normally expected forces from jostling of cargo to insure that actuation of the apparatus is intentional.

TL;DR: In this article, a model for aggregate interlock based on the behavior of micro scale is developed, where the relation between displacements and stresses across the crack faces is defined to be a function of deformation and sliding at particle level.
Abstract: A model for aggregate interlock has been developed based on the behavior of micro scale. The relation between displacements and stresses across the crack faces are defined to be a function of deformation and sliding at particle level. This relation is derived for one particle projecting from one of the crack faces with an arbitrary diameter and an arbitrary embedment depth. The most probable distribution of aggregate particles, crossed by the plane of cracking and their positions with regard to this plane are assessed by a statistical analysis. The general relations between stresses and displacements for a unit crack area are obtained by integrating all particle contributions. The model proves to give adequate results, compared with experiments, carried out on several types of (cracked) concrete. Using this model, further analysis of the mechanism of aggregate interlock has been carried out, explaining tendencies observed in tests of other investigators.
