摘要:
A tube cleaner (42) for removing deposits from the inner wall of condenser and other types of tubes has scrapers (20) for contacting the inner wall of the tube. The scrapers (20) are adapted to contact the wall so as to form an angle of 90 degrees or less rearwards of the scrapers (20) when the cleaner travels through the tube, so as to achieve more effective cleaning. The scrapers (20) may consist of one or more split rings mounted in incomplete transverse channels (44) on a central core (32).
摘要:
A connector system is disclosed. The connector system includes a single-pin plug that has at least two conductors electrically isolated from one another to provide two separate electrically conductive surfaces to facilitate simultaneously transmitting two different electrical signals through the pin at the same time. The connector system further includes a socket to receive the single-pin plug. The socket includes electrically isolated conductors to independently contact different conductive surfaces of the plug.
摘要:
A reconfigurable ADD/DROP multiplexer/demultiplexer apparatus is implemented by connecting a multiplexer/demultiplexer apparatus to a serializer/deserializer (SERDES) apparatus having a loop-back capability. By selectively activating the loop-back functionality of the SERDES apparatus the combination can be made to function as a reconfigurable ADD/DROP multiplexer/demultiplexer apparatus.
