Patent number: 4079926Abstract: An energy absorbing support formed of a composite coil defining a core and a tubular sheath with the sheath being formed of a material having a higher elastic yield strain limit than that of the core. The coil defines a first portion and a second portion with a support of the coil disposed intermediate the first and second portions. Structure is provided for applying a preselected preload to the coil. The coil materials are preselected to maintain elastic and damping characteristics at cryogenic temperatures, such as below -150.degree. F. The support is adapted for use in rigorous environments such as encountered in the space shuttle and the like, and provides lightweight, long life, resilient support of critical elements, such as piping and the like, therein.Type: GrantFiled: January 5, 1976Date of Patent: March 21, 1978Assignee: Brunswick CorporationInventor: John Nunes

Patent number: 4054521Abstract: The invention relates to a continuous and controlled filter device that filters gases and liquids while maintaining a low differential pressure across the filter element. The device automatically advances clean filter medium into the filter seat or window when the differential pressure rises to a predetermined level replacing dirty filter medium with clean filter medium. The advance of the filter medium is effected by a fluid pressure operated expansible device cooperating with an indexing device for positioning the filter medium as a function of the pressure differential extending thereacross. The indexing device may include a ratchet structure for positively positioning preselected portions of the filter medium across the flow passage through which the fluid being filtered is passed.Type: GrantFiled: September 22, 1975Date of Patent: October 18, 1977Assignee: Brunswick CorporationInventor: John P.

Patent number: 3997098Abstract: A thin perforate, helically wound welded edge tubing is used as a filter core for a roving wound filter. The slightly roughened external edges of the spirally formed welded joint greatly adds to the ability of securing the fiber roving to the tube and prevents relative slippage therebetween. Also, the invention comprehends an apparatus for, and a method of making the helically seamed tube by first drawing a sheet metal from a supply and raising two lateral edges thereof to form flanges. The material can be guided in a helical path by engaging the inside of the flanges so that the trailing edge abuts the leading edge. The abutted edges are heated so that the flanges themselves provide the filler for a weld on the exterior surface thereof. Drive rollers are provided to move the welded tube from the welding area and to torque the tube to prevent edge separation prior to the cooling of the weld.Type: GrantFiled: April 23, 1975Date of Patent: December 14, 1976Assignee: Brunswick CorporationInventor: Louis B.

Patent number: 3977847Abstract: A particle laden gas stream is cleaned by passing it through an all metal fabric including a base with pile fibers connected to the base. The flowing gas forces the pile fibers to lie down upon each other to form a depth filter media adapted to entrap fine particles. This depth filter media is cleaned to remove entrapped particles by passing air through the fabric in a direction counter to the direction the particle laden gas flows through the fabric. Consequently, the pile fibers tend to open and extend outwardly from the base, permitting entrapped particles to be carried by the air from the fabric. Apparatus including a tubular element made of an all metal pile fabric is also disclosed. The tubular element has associated with it one or more nozzles adapted to blow air through the fabric along an incremental portion of the tubular element. Consequently, a small portion of the fabric is cleaned while simultaneously the remainder of the fabric filters particles from the gas stream.Type: GrantFiled: August 8, 1975Date of Patent: August 31, 1976Assignee: Brunswick CorporationInventor: Raymond C. Clark
