Abstract: Disclosed is a device to repair ruptures in the wall of a flexible pressurizable enclosure. The device has an apertured plate on the wall's outer surface, and has a threaded fastener protruding through the aperture and rupture into the enclosure. A butterfly member threaded to the fastener within the enclosure has clamping members swingable out from the fastener so that engagement surfaces on the clamping members face the ruptured zone of the wall. A layer on the engagement surfaces has a curable adhesive resin initially segregated from a setting agent therefor, which is also in the layer. The segregation of resin and setting agent is achieved by enclosing at least one of these substances in capsules distributed within the layer. Once the clamping members swing away from the fastener, turning the fastener moves the clamping members to press them on the inner surface zone of the enclosure wall. The wall is thus sealingly pressed between the clamping members and the plate on the wall's outer surface.

Abstract: An electric power measuring system wherein the watt-hour measurements are adjusted to account for the economic effects of harmonic currents and voltages. Well known techniques are used to acquire frequency spectra that represent the voltages and currents present at the measuring point. These spectra are used to calculate power flow direction and magnitude at various frequencies. Weighting functions are applied to power flows at frequencies other than the fundamental frequency. The weighted power flow is used to calculate an harmonic-adjusted watt measurement, which is then accumulated to form a harmonic-adjusted watt-hour measurement. The weighting functions can be selected to provide an economic incentive for a power consumer to consume power in a way that matches the goals of the power provider.

Abstract: A miniature outdoor cooking unit includes a base that can be positioned on a ground surface to support a can containing flammable fuel. A protective tube is removably supported on the base to provide wind protection for the flame that is generated by the fuel. Horizontal bars on the upper edge of the tube provide a support for a pot or pan that is to be heated by the cooking unit.
