Publication number: 20040215346Abstract: An improved lower leg prosthesis is disclosed for providing an improved performance, including improved stability and improved multi-axial compliance. The prosthesis includes upper and lower foot plates and an elastomeric layer disposed between and attaching them together. The elastomeric layer extends substantially across an upper surface of the lower foot plate. The elastomeric layer preferably being narrower in width than the upper and lower foot plates in a middle portion of the layer. The prosthesis alternatively includes upper and lower foot plates and an attachment device coupled to the upper foot plate and adapted for connection to an external prosthetic component. The attachment device includes a lower surface that conforms to a sloping portion of the upper foot plate and preferably includes a generally horizontal mounting portion having a mounting protrusion, such as a pyramid adapter.Type: ApplicationFiled: March 19, 2004Publication date: October 28, 2004Inventors: Eric W. Rubie, Larry J. Hansen, Nathan A. Williams, David J. Wall, John B. Merlette

Patent number: 6712860Abstract: An improved lower leg prosthesis is disclosed for providing an improved performance, including improved stability and improved multi-axial compliance. The prosthesis includes a two-part lower foot plate, incorporating a forefoot plate and a heel plate, and an upper foot plate that is attached to the forefoot and heel plates by a two-part intermediate elastomeric layer. Forming the lower foot plate and the elastomeric layer each in two parts ensures that the forefoot plate and heel plate function substantially independently of each other, which leads to substantially improved cushioning at heel strike and to improved stability throughout the gait cycle.Type: GrantFiled: February 9, 2001Date of Patent: March 30, 2004Assignee: Otto Bock Healthcare LPInventors: Eric W. Rubie, Larry J. Hansen, Nathan A. Williams, David J. Wall

Patent number: 4249464Abstract: A meal rack is constructed in order to double the usable oven space in a microwave oven. The meal rack has a grid frame with open space allowing for the dissipation of moisture. The legs used to elevate the meal rack frame are easily engaged and disengaged.Type: GrantFiled: February 9, 1979Date of Patent: February 10, 1981Inventor: Larry J. Hansen

Patent number: 4196169Abstract: A system for disposing of radioactive mixed liquid and particulate waste material from nuclear reactors by solidifying the liquid components into a free standing hardened mass with a syrup of partially polymerized particles of urea formaldehyde in water and a liquid curing agent.Type: GrantFiled: September 20, 1976Date of Patent: April 1, 1980Assignee: Nuclear Engineering Company, Inc.Inventors: Kenneth A. Gablin, Larry J. Hansen

Patent number: 4168243Abstract: A system for disposing of radioactive waste material from nuclear reactors by solidifying the liquid components to produce an encapsulated mass adapted for disposal by burial. The method contemplates mixing of radioactive waste materials, with or without contained solids, with a setting agent capable of solidifying the waste liquids into a free standing hardened mass, placing the resulting liquid mixture in a container with a proportionate amount of a curing agent to effect solidification under controlled conditions, and thereafter burying the container and contained solidified mixture. The setting agent is a water-extendable polymer consisting of a suspension of partially polymerized particles of urea formaldehyde in water, and the curing agent is sodium bisulfate.Type: GrantFiled: March 24, 1976Date of Patent: September 18, 1979Assignee: Nuclear Engineering CompanyInventors: Kenneth A. Gablin, Larry J. Hansen

Patent number: 4167491Abstract: A method of disposing of wet radioactive waste materials such as those generated in the water used to cool atomic reactors, comprising combining the waste material with a hydrophilic resin in proportions sufficient to provide a solid mass of the resin with the radioactive waste component distributed within. In its preferred form, the waste material is concentrated by separating water from the radioactive portions thereof by methods such as evaporation, taking up the waste components with an ion exchange resin and separating the resin from the bulk of the water, or by the addition of flocculating agents or the like and filtering. The preferred hydrophilic resinous material is a conventional urea-formaldehyde dispersion, which is partially polymerized and capable of taking up water and fully polymerizing upon the addition of an acidic curing agent.Type: GrantFiled: June 7, 1976Date of Patent: September 11, 1979Assignee: Nuclear Engineering CompanyInventors: Kenneth A. Gablin, Larry J. Hansen

Patent number: 4100860Abstract: A shipping container overpack for safe transportation of radioactive and other hazardous materials provides a leakproof receptacle for containing and protecting the material to be shipped against accidental release and dispersal into the surrounding environment. The receptacle is of conventional size and shape for shipping containers and has spaced inner and outer shells with a layer of foamed polyurethane occupying the space therebetween to provide sealing, insulation and reinforcement. The polyurethane foam is rigidly compressible and adheres to and reinforces the spaced inner and outer shells to provide a stress skin structure. Gusset plates are secured to the inner surface of the outer shell in covering relation to the corners and edges, defining a reinforcing framework of triangular cross-section tubular elements. Relatively rigid polyurethane foam is containd within the tubular elements to add further reinforcement and redundant sealing capacity.Type: GrantFiled: November 26, 1973Date of Patent: July 18, 1978Assignee: Nuclear Engineering Co., Inc.Inventors: Kenneth A. Gablin, Larry J. Hansen
