Abstract: Provision is made in an organic rankine cycle power plant for modulating the flow of hot gases from a thermal source to the evaporator. The modulation device may be a blower on the downstream side of the evaporator or a valve on the upstream side thereof. The modulation device is controlled by generation of a digital signal to enable or disenable the modulation device and an analog signal for adjusting the position of the modulation device.

Abstract: The shaft (20) of an engine (19) is coupled to a turbine (28) of an organic Rankine cycle subsystem which extracts heat (45-48, 25) from engine intake air, coolant, oil, EGR and exhaust. Bypass valves (92,94, 96, 99) control engine temperatures. Turbine pressure drop is controlled via a bypass valve (82) or a mass flow control valve (113). A refrigeration subsystem having a compressor (107) coupled to the engine shaft uses its evaporator (45a) to cool engine intake air. The ORC evaporator (25a) may comprise a muffler including pressure pulse reducing fins (121, 122), some of which have NOx and/or particulate reducing catalysts thereon.

Abstract: A tee assembly for use between horizontal raceway sections and a vertical raceway has a divider that separates the cables running between separate wireways in these raceways. The divider has unique ramps to guide fiber optic cables around generous radii, and is also reversible to lend a degree of flexibility to the divider.

Abstract: A modular faceplate assembly having a faceplate and at least one modular panel received and supported within a frontal opening in the faceplate and releasably secured to the faceplate by concealed latches hingedly connected to the modular panel rearward of the faceplate for flexure between latching and releasing positions relative to keepers carried by the faceplate and resiliently biased to said latching positions. When the latches are in latching positions latch operators carried by the latches form closures for latch operating apertures opening through the frontal surface of the faceplate assembly. Cam surfaces on the latch operators facilitate operation of the latches to release the panel from the faceplate in response to insertion of an operating tool into the latch operating apertures.
