摘要:
A cleaning system for cleaning the inside of fluid conduting tubing (14). The cleaning system includes a plurality of balls (26) entrained by a fluid flowing through the system, separation apparatus (28) for separating the balls (26) from the fluid downstream of the tubing (14), accumulator apparatus (60) for accumulating the balls downstream of the separation apparatus (28), storage apparatus (62) for storing a volume of injection fluid and a compressor (64) for selectively providing a supply of compressed air into the storage apparatus (62) such that a portion of the volume of injection fluid passes through the accumulator apparatus (60) for entraining some of the balls (26) therewith for injection upstream of the tubing (14).
摘要:
A system for automatically calling the drivers attention to the upcoming need to bring his vehicle to a stop, which includes a transmitter (12) located at a fixed location along the roadway in the vicinity of the area where the vehicle is to come to a stop. The transmitter (12) transmits signals directed at oncoming vehicles. The system further includes a receiver (14) connected to an incoming vehicle for receiving the above signals. Finally, the system includes a mechanism (16) for outputting a warning message to the driver which is related to the signals received by the receiver (14).
摘要:
An extendible-retractable device, which is made up of a number of interconnected members (10, 12, 14) and to which a suitable tool (44) may be attached. The device makes it possible to continually change the position of the tool (44) as a task is being performed. The device includes members (10, 12, 14) which are attached to each other through flexible cables (16, 22, 30, 32) so that relatively small movements of a handle (20) or similar device in the hand of the user results is relatively large extension or retraction movements of the farthest member (14) which carries the tool (44).
