Abstract: A satellite system can include one or more satellites that orbit the Earth. The one or more satellites may have satellite buses that support antenna arrays. The antenna arrays may include space fed arrays. Each space fed array may have an antenna feed array and an inner array that is coupled to a direct radiating array. The direct radiating array may operate in the same satellite band as the space fed array, or upconversion and downconversion circuitry may be used to communicatively couple a direct radiating array that operates in a different satellite band to the space fed array. The satellites may have peripheral walls with corner fittings that can be selected to provide the satellite bus with particular leg strengths. This can reduce overall mass of the satellites in a payload fairing while accommodating different types of antenna arrays.

Abstract: A wall assembly for bearing a concrete slab has a wall framework including a bottom plate, a top plate extending parallelly to the bottom plate and vertically spaced-apart from the bottom plate. Vertically extending stud members are spaced-apart from one another along a length of the wall framework and extend between the bottom plate and the top plate. At least one of the top plate and the bottom plate includes vertical translation components, which are aligned with the vertically extending and spaced-apart stud members, and is engageable with the vertically extending stud members through the vertical translation components. The wall framework can facilitate vertical translation of the at least one of the top plate and the bottom plate relative to the vertically extending stud members upon application of a substantial weight on the wall framework. A concrete containment wall assembly is used in combination with a wall framework.

Abstract: A versatile container a versatile pipe section comprising a sleeve and a tube inserted into the sleeve, the tube being held in place using a first capping element at a first end, at least one mounting element in a middle portion and a second capping element at a second end. The first and second capping elements are provided with an opening of a diameter corresponding to the diameter of the tube for allowing liquid or gas to flow through the tube. Also, a versatile container comprising a sleeve, at least one liquid or gas holding compartment adapted to be positioned within the sleeve, the at least one compartment being held in place using at least one mounting element. The sleeves are adapted to hold the contents of the tube or the at least one compartment in case of a leak.

Abstract: An insulating wall assembly, including a framework having opposite interior and exterior sides and including a plurality of vertical and horizontal support studs defining an inner spacing within the framework, a substantially rigid insulating panel mounted to the framework, and an insulating material extending in the inner spacing and juxtaposed to the rigid insulating panel. Each one of the vertical and horizontal support studs has an outer stud member having a thickness t1 and an inner stud member mounted inwardly to the outer stud member and having a thickness t2 thinner than the thickness t1. The substantially rigid insulating panel is supported peripherally by the inner stud members with the outer stud member circumscribing the rigid insulating panel.

Abstract: A hot water tank comprising a sleeve, a removable top lid, at least one changeable water holding compartment adapted to be stacked vertically within the sleeve, stacked compartments being connected by a connecting pipe and at least one heating means provided with one of the compartments. The changeable compartments are configured to be removable from the sleeve upon removal of the top lid in case of failure and the space between the sleeve and the changeable compartments is adapted to hold the contents of the compartments during a leak.

Abstract: This invention relates generally to hot water tank but more particularly to a hot water tank having a removable top lid. The hot water tank comprises a sleeve lining the tank; at least one compartment housed within said sleeve, the compartment having walls for containing water; and a top removable lid; and wherein said sleeve and said compartment are removable from the tank upon removal of said top lid. The sleeve can be sealed or not and has as its particularity that it can be extremely versatile and can have changeable water containers with heating means or not. The sleeve can be adapted to any existing or future water container of any size or model, with or without heating means, and has the possibility of having one or many individual water compartments being exchangeable upon rusting/piercing/breakage, instead of changing the complete tank. The sleeve can also hold the entire contents of the hot water container, if it pierces.

Abstract: A water management and leak detection has a containment system to contain hot water tank leaks and and electrical circuits that manage water flow and electricity to the hot water tank.
