Abstract: An electrical connector modularly arrayed for ease in manual and automatic fabrication and assembly of wire bundle assemblies. Increased structural strength, elimination of snap ring, straight bore inside diameter, the addition of an insert alignment key, and elimination of electrical contact retention clips are features of the present modular electrical connector assembly.

Abstract: A knife for cutting honeycomb core and other materials with a combination of safety features to prevent or minimize injury to operator. The blade used has a hole through which a fastening device e.g. threaded screw, locks it to a handgrip. A safety guard covers the blade when not in use and automatically retracts as the blade is removed from the workpiece. The guard cannot be accidently displaced from the blade. It must be purposely unlocked by a manually triggered self-locking release assembly located in the handgrip which also automatically relocks the safety guard when retracted. The safety features consist of an automatically retractable guard attached to a safety handshield working in conjunction with the safety self-locking release assembly to prevent accidental release.
