Abstract: The invention provides a disconnectable band saw joint assembly for connecting together in axial alignment end portions of a bandsaw. The joint assembly does not require welding, and as such can be easily separated to permit threading of the bandsaw through a hole drilled in a plate to permit sawing of a closed ended cut or loop within the plate. This eliminates the normal practice of breaking and rewelding a band saw for cutting a closed loop within a plate. Furthermore, because the joint is cold, it does not affect temper of the saw portions adjacent the joint. The assembly has male and female connections, the female connections having a neck recess and a head recess, and the male connection having a head portion and a neck portion which fit within the neck recess and the head recess respectively. The recess has at least one main recess edge, and the head portion has at least one main head edge, both edges being disposed normally to longitudinal axis of the saw.

Abstract: This invention relates to a coupling device for tubular members (11 and 12), of large truss structures, with a locking collar 20 being the only moving part. Each tubular member is constructed with an end bell section 15 that has a belled flange 17 with a mating face 18, and a necked area 16 which is smaller in diameter than the tubular members to be joined. A split ring 30 is affixed to each tubular member and is constructed so that then two tubular members are laterally moved into axial alignment and collar 20 is rotated thereover, the split ring loads the joint with axial force by pressing the belled flange mating surfaces together, and a preloading force is provided by the collar 20 mating with a taper on the outside of the split rings. All free play is thereby removed by preloaded force. A major object of the invention is to provide an ability to remove and replace individual tubular members without disturbing other structural parts of a truss structure.

Abstract: A delayed restraint releaseable device utilized to restrain and controllably release the lower end of an inflating escape slide at a predetermined pressure, orientation and time. The device combines two distinct restraint mechanisms into one combination unit. The primary release is accomplished by means of shear pin or pins located at the first end of the device. Under normal conditions, the release is accomplished by shearing of the pin or pins under the load provided by the tied back inflating slide. The back-up release, in series with the primary release, occurs when the pressure of the reduced load causes a piston within the restraint to move against both a spring and captive fluid. As the piston moves, the fluid transfers through a precise sized orifice in the piston, from one side of the piston to the other. The piston moves eventually to a point at which the interlocking leg of the piston support shaft is released, thus allowing the ends of the mechanism to separate.
