A neutron tube or generator is based on a RF driven plasma ion source having a quartz or other chamber surrounded by an external RF antenna. A deuterium or mixed deuterium/tritium (or even just a tritium) plasma is generated in the chamber and D or D/T (or T) ions are extracted from the plasma. A neutron generating target is positioned so that the ion beam is incident thereon and loads the target. Incident ions cause D-D or D-T (or T-T) reactions which generate neutrons. Various embodiments diff...

Discharge tubes for a lamp include a body portion with a first end, a second end, and a tubular member defining an interior area. The tubular member extends along an elongated axis between the first end and the second end. The discharge tube further includes a first end portion provided at the first end of the body portion. The first end portion includes a first tubular extension having a first through passage in communication with the interior area. The first end portion further includes a firs...

The invention relates to a machine for producing a tube provided with a nipple in each end controlled by a process-computer. The machine comprises a plurality of stations where machining of the tube shall be made, the tube primary product being rolled up on a roll which is arranged in a tube roll stand. According to the invention, the machine includes transport of the tube to and from respective stations wherein the tube is fed from the roll up to a measuring and cutting station, where the tube ...

A tracheostomy tube has a sealing cuff inflated by an inflation tube extending in a channel along one side of the tracheostomy tube. A suction tube extends in a channel along the opposite side of the tracheostomy tube. The suction tube extends to the upper end of the sealing cuff and opens into a recess on the outside of the tracheostomy tube through a side opening oriented at right angles to the radius of the tracheostomy tube. The recess extends around about 90.degree. of the tube towards its ...

There is provided telescoping tube apparatus including an outer tube 11, an intermediate tube 12 and an inner tube 13. The tubes can be telescoped together to provide a single tube of variable length by use of joining sleeves 21 and locking sleeves 31. The joining sleeves 21 include jaw means 24 which is acted upon by the locking sleeves 31 to lock the tubes in the desired position.

The lipstick tube (20) has a cap (5) to be coupled by pressure on a collar (4) emerging axially from the tube body (1), characterised in that it comprises a ring of material (6) having a flexible free end (16), said ring (6) being provided with an external rabbet or recess (9) around the periphery close to its free end defining an annular void (10) between the free end (16) of the ring (6) and, respectively, the cap (5) or the collar (4), towards which the ring (6) may be elastically deformed wh...

Reinforced, cuffed tubes are made by winding a plastic reinforcing filament around the outside of tubing and then applying a flexible layer on top of the tubing to just cover the filament and form a smooth outer surface. The filament is then removed from regions of the tubing using a pick to form a series of reinforced regions and unreinforced regions along the tubing. A second layer is then coextruded over the reinforced and unreinforced regions, which includes a longitudinal lumen. The tubing ...

In an electron tube including vibration absorbers for linear members such as filaments, a vibration absorbing means that is made of a vibration absorber with a large vibration absorption effect, has a simple configuration, and is attachable easily to filaments is provided. The vibration absorbing means is formed of a holder 231, a vibration absorber 241, and a getter shielding member 251. These three members are attached to a shielding electrode S overlying the front substrate 111 to dispose the...
