Patent number: 5163287Abstract: In order to optimize ignition capabilities, while at the same time enhancing the life span of an igniter, a stored energy combustor (10) has an igniter (34) disposed within a fuel injector (26). The fuel injector (26) is disposed in a tubular extension (16) leading to a combustion chamber (20) and has a discharge end (28) communicating with a point of entry into the combustion chamber (20). An oxidant inlet port (24) is provided upstream of the combustion chamber (20) for directing oxidant into the combustion chamber (20). The oxidant inlet port (24) directs oxidant through the tubular extension (16) leading to the combustion chamber (20) in surrounding relation to the fuel injector (26). With this arrangement, the igniter (34) is disposed within the fuel injector (26) along a longitudinal axis (22) of the stored energy combustor (10).Type: GrantFiled: December 22, 1989Date of Patent: November 17, 1992Assignee: Sundstrand CorporationInventors: Jack R.

Patent number: 5103632Abstract: Difficulties in accommodating thermal growth in a combustor for providing hot gases of combustor to drive, for example, a turbine wheel (10) are avoided in a combustor construction, including a housing (36) defining a combustion chamber having a relatively narrow inlet (38), an enlarged combustion area (42) and a relatively narrow outlet (40) opposite of the inlet (38). A fuel injector (46) is disposed in the inlet (38) for injecting fuel (50) at least into the combustion area (42) and a plenum case (56) surrounds the housing (36) in generally spaced relation. The plenum case (56) is adapted to be connected to a source (62) of oxidant under pressure and is in fluid communication with the inlet (38) to provide oxidant thereto to support combustion of fuel in the combustion area (42). A conduit (44) extends from the outlet (40) to be connected to a turbine nozzle (16) and a diaphragm (122) is interposed and sealingly engages both the housing (36) and the plenum case (56) near the outlet (40).Type: GrantFiled: January 29, 1990Date of Patent: April 14, 1992Assignee: Sundstrand CorporationInventors: Steve Heitz, Robert W.

Patent number: 5024058Abstract: Improved performance in a hot gas generator 10 is achieved by providing a liner 21 positioned within a wall 14 of a vessel 12 so as to be disposed about a combustion chamber 20 therein. The liner 21 is positioned relative to the wall 14 to define a relatively uniform gap 26 therebetween and is adapted to thermally expand under heat for controlling heat transfer from the combustion chamber 20 through the liner 21 and the wall 14 entirely throughout a preselected temperature range. With this arrangement, the gap 26 is selected to accommodate thermal expansion of the liner 21 in a manner producing relatively little stress thereon.Type: GrantFiled: December 8, 1989Date of Patent: June 18, 1991Assignee: Sundstrand CorporationInventors: Jack R.

Patent number: 5022348Abstract: A livestock feeding apparatus provides continuous flow of feed to an elongated bunk utilizing a traveling hopper supported for movement along rails on an elongated frame over the bunk. The hopper includes a gate extending substantially along the full length of the bottom opening of the hopper for bulk dumping of the feed when the hopper is over one of the two dumping stations adjacent the two ends. The gate is actuated during opening and closing so as to travel along a sliding path to assure efficient delivery of the feed with a clean cut-off. Preferably, the gate moves at an acute angle to the longitudinal axis of the hopper and along an arc defined by pivotal support links. Cam wheels adjacent the ends of the hopper engage ramps for opening and closing the gate as the gate moves along an arcuate path defined by the parallelogram linkage. In the preferred embodiment, the wheels drop off the top of the ramps providing sudden release for rapid and secure closing of the gate. A 20.degree.Type: GrantFiled: October 30, 1989Date of Patent: June 11, 1991Assignee: Badger Northland Inc.Inventors: Gerald J. Bruecker, Robert W. Smith

Patent number: 4970865Abstract: A spray nozzle including a body having a fluid inlet at one end thereof and an exit orifice at the other end thereof. The fluid inlet communicates with the exit orifice through a fluid flow path extending through the body. The exit orifice is adapted to atomize the fluid as the fluid leaves the body. The spray nozzle also includes a separate portion for atomizing the fluid independent of the exit orifice. The separate portion communicates with the fluid flow path upstream of the exit orifice. The separate portion produces a flat spray of the fluid as the fluid leaves the body. With these features, the spray nozzle is well suited as a fuel injector for a gas turbine.Type: GrantFiled: December 12, 1988Date of Patent: November 20, 1990Assignee: Sundstrand CorporationInventors: Jack R.

Patent number: 4713929Abstract: In the operation of certain agricultural and industrial pursuits an excess of various chemicals results. For example, an excess of phosphorus results from the use of fertilizers in the general farming operations of stimulate the growing of grass in the dairy rich areas of central Florida. This excess quantity of phosphorus finds its way into the streams and rivers, and contaminates any of the streams and bodies of water that receive the outflow of these chemically rich waters. For example, the Kissimmee River flows through the dairy rich lands of central Florida and contaminates Lake Okeechobee into which they flow. Many other chemicals used as lubricants and additives in industrial operations that also are discharged into the various bodies of water are harmful to the fish and aquatic plants whose presence is necessary to recycle and purify the water.Type: GrantFiled: March 9, 1987Date of Patent: December 22, 1987Assignee: Colony Services Inc.Inventor: Robert W.

Patent number: 4685555Abstract: A hook line includes a hook portion and a link portion contained in two different planes substantially perpendicular to one another. A projection tip is provided on a distal end of the hook portion to provide secure locking action between adjacent hook links; the normal clearance between the tip and the connected link portion being insufficient to allow coupling/uncoupling action. A tip receiving groove extends substantially laterally across the elongated ring forming the link portion. The ring defines a longitudinal slot for receipt of said hook portion. The groove of one hook link receives the projection tip of an adjacent hook link to allow coupling/uncoupling action. In the preferred embodiment, the groove extends along an arc between a transverse midline of said longitudinal slot and an end of said longitudinal slot opposite said hook portion. The groove and tip structure substantially eliminates uncoupling during normal conveyor operation even when subjected to incidental slackening.Type: GrantFiled: November 14, 1985Date of Patent: August 11, 1987Assignee: Badger Northland, Inc.Inventor: Robert W.
