Patent number: 4640043Abstract: An explosive trap for burrowing rodents is comprised of an elastic sack and an associated support frame which are placed in a tunnel that is formed adjacent to the rodent's run. The frame includes a pointed spike which punctures the sack when it expands to a predetermined size upon inflation by the pressurized gas. The resulting explosion provides a concussive shock which kills the rodent. The sack is fluidly connected to an above ground container which can be filled with the pressurized gas through a length of hose, and a valve located at the outlet of the container normally prevents the gas from flowing from the container into the sack. A trigger located outside of the rodent run above its clean-out hole causes the valve to be opened and release the gas from the container, so that it will inflate the sack, when the rodent pushes more dirt out of the clean-up hole.Type: GrantFiled: June 14, 1985Date of Patent: February 3, 1987Inventor: Perry J.

Patent number: 4620662Abstract: A process for brazing a sleeve within a tube which is resistant to longitudinal expansion is disclosed herein. In the first step of the process, a thermally induced radial expansion is induced in the tube in a first longitudinal section of the tube which does not include the ring of brazing alloy which circumscribes the sleeve. In the second step of the process, a brazing heat is applied across the longitudinal section of the tube which does include this ring of brazing material. The residual tensile stress created by the thermally induced radial expansion in the tube avoids the creation of gaps in the braze joint between the sleeve and the inner walls of the tube. This process is particularly useful in creating high-quality braze joints in sleeving operations in nuclear steam generators, where the heat exchange tubes which need to be sleeved may be partially or completely prevented from expanding in the longitudinal direction due to sludge deposits in the generator.Type: GrantFiled: July 25, 1984Date of Patent: November 4, 1986Assignee: Westinghouse Electric Corp.Inventor: John M. Driggers
