摘要:
The present invention relates to systems and methods to facilitate replacement between runs of a kit or cassette from an automated radiosynthesis device located in a hot cell. The method and apparatus of the invention enable automated disconnection of the outlet line by sealing the tubing hermetically by means of heat and by cutting the tubing where it is sealed in such a way that there is no risk of environmental contamination with radioactive material. The invention enables disconnection of the outlet line without manual intervention before opening the shielded enclosure.

The displacement mechanism includes: an urging mechanism that urges an anvil roller toward an ultrasonic horn in such a manner that output surfaces and a welding surface move closer in the normal direction thereof; and a pressed member that has guide surfaces against which the outer surface of the anvil roller, positioned within non-welding areas, are pressed by an urging force of the urging mechanism, the pressed member being fixed to a sheet holding roller in a state where a pressed surface is disposed within the width-direction range of a slit. In response to the movement of the anvil roller from a welding area to the non-welding areas, the guide surfaces of the pressed member guide the anvil roller in a direction in which the output surfaces and the welding surface move away from each other.

摘要:
Dot Hot Stapling is provided wherein articles such as bags can be made of interwoven or knitted plastic material and wherein the interfitting or interwoven strips are adapted to be sealed together so as to prevent unraveling and to provide an economical method of making such articles. With the present invention, crossing points of tape type fabrics are attached together with dot sealing or dot hole edge sealing by any means that will accomplish this function. The dot heat sealing may be accomplished in any of plurality of ways such as by using heated needles, co-acting rollers with heated prongs, pulsed laser, interrupted heated air jets, a pulsed spark arrangement, intermittent ultrasound, ultrasonics, or the like.
