Abstract: Methods of braiding using a braiding mechanism are described. The braiding mechanism includes a disc defining a plane and a circumferential edge, a mandrel extending from a center of the disc that is adapted to hold a plurality of filaments extending radially from the mandrel toward the circumferential edge of the disc, a plurality of catch mechanisms positioned circumferentially around the edge of the disc, a plurality of actuators adapted to move the plurality of catch mechanisms in a substantially radial direction relative to the circumferential edge of the disc, and a plurality of filaments extending radially from the mandrel towards circumferential edge of the disc. A middle portion of each filament of the plurality of filaments contacts an end of the mandrel.

Abstract: A pneumatic dispenser gun for two part viscous materials comprising two parallel containers containing the two materials and a pneumatic cylinder 12 whose axis is parallel to the axes of the two containers and which contains a piston 15 having symmetrically mounted piston rods 17, 18 extending through the end wall of the cylinder into the containers to expel the contents of the two containers simultaneously through a common outlet passage. A further rod 19 extends from the piston parallel to the piston rods but outside the containers to provide an indication of the amount of contents remaining in the containers and a handle for returning the piston to its initial position.

Abstract: A gun for dispensing viscous material, for example a mastic caulking material, and comprising a holder for a cartridge projecting from one edge of a generally plate-like stock in which a rod is mounted for movement longitudinally of itself, and a mechanism for advancing the rod longitudinally of itself to express material from the cartridge. The rod is mounted in the plate-like stock by being passed between bridge portions integral with the stock and deformed out of the general plane of the stock in opposite directions.
