A transportable modular building includes a shipping container having shipping container frame members defining an outer periphery of the shipping container; shipping container periphery walls extending between the shipping container frame members, and an entry wall unit. The entry wall unit is recessed from the shipping container frame members that form a first side. The entry wall unit includes a door; a solar panel power interface to interface with a solar panel. The shipping container is suitable for national and international conveyance using conventional transportation networks.

A capacitor arrangement which is especially suited for use in an electronically tunable narrow band tuned cavity filter includes two capacitor plate portions which are juxtaposed one another to form a capacitor. One of the capacitor plate portions may be provided with a recess and with an internally threaded bore which opens into the recess, and an externally threaded trimmer slug may be received in the bore and extend to a greater or lesser degree into the recess and thus to contribute to a greater or lesser degree to the total capacitance of the capacitor. A dielectric spacer may be interposed between the capacitor plate portions to determine the size of the gap therebetween and to maintain the gap size constant. One of the capacitor plate portions may be mounted on a support for movement toward and away from the other capacitor plate portion and be urged toward the latter in a yieldable manner so as to avoid undue stressing of the dielectric spacer resulting either from vibrations or from thermal expansion. When the capacitor arrangement is to be used in a tuned cavity filter including a plurality of resonator bars which are mounted in a cantilevered fashion, a portion of the respective resonator bar may be used as one of the capacitor plate portions, and a set of the capacitor arrangements of this construction may be arranged around the respective resonator bar so as to suppress oscillations of the latter in all transverse directions.

Capacitor arrangements, especially for an electronically tunable band

An electronically tunable narrow band tuned cavity filter includes a housing which bounds a tuned cavity, a plurality of resonator bars secured to the housing, extending across the tuned cavity and having respective extensions that pass through respective openings of the housing to the exterior of the tuned cavity, and a set of tuning capacitor plates for each of the resonator bars. The tuning capacitor plates associated with the respective resonator bar are arranged outside the tuned cavity around the extension in a compartment surrounding the opening, together with respective switching networks driven by an electronic drive and operative for including the capacitor plates in or excluding the same from electric circuit with the respective resonator bar. The capacitor plates may be directly juxtaposed with associated facets of the extension to form respective tuning capacitors therewith. Dielectric spacers may be interposed between the capacitor plates and the associated facets of the extension to determine and maintain the size of the gap therebetween, and to suppress mechanical vibrations of the cantilevered resonator bar. The capacitor plates may be yieldably mounted on the support and urged toward the extension by respective springs. The extension of the resonator bar may be provided with a recess opening onto the respective facet, and an internally threaded bore opening into the recess, and externally threaded trimmer slug may be received in the bore and extend to a greater or lesser degree into the recess to thereby contribute to a greater or lesser degree to the total capacitance of the respective tuning capacitor.

A luminous aid for indicating a pre-selected emergency number disposed in proximity to means for indicating the appropriate digits to be used on a telephone dial serves to permit the telephone to be operated without requiring additional illumination. A marking assembly for so preparing the telephone includes a pliant sheet of coated material carrying both a label indicating the emergency number as well as continuously luminous markers for use in marking two digits on the telephone dial.
