Patent number: 7708960Abstract: A dry heat sterilization system having a housing and a number of plenums to guide the flow of hot air. Hot air is forced to flow through the plenums, the intake slide duct and into the bottom of the containers. The hot air will rise and exit from the top of the container through the exhaust slide duct. Furthermore, the external surfaces of the container are also sterilized through the use of semi-pierced duct walls with adjustable diffuser panels. Hot air will re-circulate until it reaches a pre-determined temperature. The container and its contents can be safely handled once the exhaust air blower removes hot air from the system.Type: GrantFiled: March 31, 2006Date of Patent: May 4, 2010Assignee: SPX CorporationInventors: Gary C.

Patent number: 7710342Abstract: A dual-port corporate-feed broadband antenna uses two pairs of crossed dipoles in each bay, fed by a single hybrid coupler in each bay, to support hybrid-mode IBOC® VHF-band broadcasting. Each 3 dB quarter-wave coupler receives a share of an analog FM broadcast signal on a first input and a digital OFDM broadcast signal, 20 dB down, on a second input. The respective coupler output ports drive coaxial lines to tees feeding respective quarter-wave-separated crossed dipoles. The dipoles in each bay are arranged in a square to one side of their coupler, making side mounting practical. The resultant omnidirectional analog and digital radiation patterns have the same circular polarization and opposite phase rotation. Bay spacing for vertical null is a function ((n?1)/n) of the number of bays in the antenna.Type: GrantFiled: May 24, 2007Date of Patent: May 4, 2010Assignee: SPX CorporationInventors: John L.

Patent number: 7683849Abstract: A vertically polarized traveling wave antenna forms peanut-type directional lobes without significant nulls between the lobes. A self-supporting coaxial line feeds quad-dipole bays coupled around the coaxial line, with opposed dipole pairs spaced along the coaxial line. Matched-layer spacing provides substantial cancellation of the reactive components of the loads. Dipoles are oriented parallel to the coaxial line axis, with opposite “hot” (center coupled) elements oppositely oriented. Radiated signals have rotating phase. Changing the spacing within quads from a quarter wavelength or rotating the second dipole pair of each quad away from a right angle causes the antenna to radiate strongly on one axis and weakly at right angles thereto, without the nulls of back-to-back panel antennas.Type: GrantFiled: July 12, 2007Date of Patent: March 23, 2010Assignee: SPX CorporationInventors: John L.
