摘要:
A method of operation of a thermal power plant having an air separation system with a plurality of air storage unit (ASU) compressors and a liquid oxygen/liquid air (LOX/LA) storage facility for oxyfuel firing of fossil fuel and a power plant having a control system to perform the same are described. The method is characterized by the step of controlling the net power output of the plant in response to short term variations in grid demanded net plant output by dynamically adjusting the works power of the ASU compressors preferably in conjunction with co-ordinated changes in firing demand. The method is in particular a method to produce an improved primary and secondary response to transient changes in grid demand and to provide accurate response to load dispatch ramps.

A lamp (100) includes a main body (11) and a removable cover (10). The main body (11) includes a lamp housing (111), a printed circuit board (112), light emitting elements (113), and a threaded base (114). The lamp housing (111) defines a socket (115) receiving the printed circuit board (112) and the at least one light emitting element (113) therein. The printed circuit board (112) is electrically connected to the light emitting elements (113) and fixed in the socket (115). The removable cover (10) includes a light-transmission portion (101) and a connection portion (102) which connects to the end of the lamp housing (111) defining the socket (115). The light-transmission portion (101) is opposite to the socket (115). Light from the at least one light emitting element (113) emits through the light-transmission portion (101).

A safety helmet (1) having a fitment (150) for a fitment clip (120, 140) for fitting a helmet accessory configured to receive either a first clip (120) having: two downwardly-depending resilient arms (121); a clip portion at the end of each arm; a downwardly-depending tab (122); a support section to engage a surface of the helmet; and an outer surface for fitting an accessory thereto; or a second clip (140), having: a first tab (141); and a resilient projecting second tab (142); the fitment (150) comprising: a slot (151) to accommodate a tab (122) from the first clip (120) or a tab (141) from said second clip (140); a through aperture (153) on an outer surface to accommodate a projecting tab (142) of a second clip (142) and thereby fixing the fitment clip (140) in position; and an outer surface adjacent an edge of the helmet such that, when a first clip (120) is located in said fitment (150), clip portions of the arms (121)of the first clip (120) pass under the helmet (1) to hold the fitment clip (120) in position.
摘要:
A vehicle headlamp system (100) includes a lamp device (12; 22) and a control device (14) to control the brightness thereof while in operation. The lamp device includes at least a first light emitting diode unit (126; 226; 326) providing a first color temperature, and at least a second light emitting diode unit (128; 228; 328) providing a second color temperature different from the first color temperature. The control device is coupled to the lamp device for changing the brightness ratio of the second LED unit to the first LED unit and controlling the resulting color temperature of the lamp device.
摘要:
A filter assembly that includes a filter body defining a mouth, a filter element disposed in the filter body, and a seal disposed on the mouth. The seal has a seal body defining a center axis. The seal body has an axial surface perpendicular to the center axis and an outer annular surface revolved about the center axis. A portion of the outer annular surface defines at least one of an arcuate and a substantially frustoconical shape.
