  • Retrofitted railway car and method of producing same
    Patent number: 4589348
    Abstract: A gondola tub type railway car having an arrangement for transferring payloads from the car side panels more directly to the bolsters. The car at each end has a lower bolster for support by a car truck, and an upper bolster secured to the lower bolster preferably through a shear plate. A center plate unit extends upwardly from the lower bolster into the upper bolster and is secured to the latter. The car, at each end, is provided with a reaction beam located inboard of the associated bolster, and is secured to the shear plate and to side members, and cooperates with the bolster in resisting the couple created by draft and buff forces acting in offset relation to the plane of the shear plate.

  • PLURAL HEAT PUMP AND THERMAL STORAGE SYSTEM FOR FACILITATING POWER SHAPING SERVICES ON THE ELECTRICAL POWER GRID AT CONSUMER PREMISES
    Publication number: 20170227299
    Abstract: A system and method for storing energy from an electrical grid utilizes a system heat pump at a premises for transferring energy from the grid to a thermal storage reservoir and a premises heat pump that can use the stored energy to provide, for example, heat to the premises. The system heat pump and premises heat pump desirably operate independently of one another so that energy can be transferred to the thermal storage reservoir regardless of whether energy is being withdrawn by the premises heat pump. Plural energy storage systems utilizing respective system and premises heat pumps and thermal storage reservoirs can form a part of the utility customer system with the system heat pumps being operable to shape the load on the electrical grid. A system heat pump can be operated to minimize a customer's bill, or the utility's cost and alternatively to achieve other purposes, depending upon the mode of operation of the system.

  • Rock treating method and compositions
    Patent number: 4256501
    Abstract: A method is provided for upgrading rock, for example building block, aggregate, preexisting stone structures, portland cement and bituminous concrete structures to render such rock more resistant to degradation resulting from environmental exposure. An organic condensation polymer containing rock treating composition in the form of a solution or dispersion is also provided based on the use of an organic condensation polymer, such as a silicone-arylpolycarbonate block polymer, an organic aliphatic polyamine and an organic solvent, as well as treated aggregate and improved cement and concrete compositions containing such treated aggregate.
