For the fabrication of a fibre by drawing a preform, the latter is obtained by sinking a thick silica tube (2) to which a vacuum is applied and which is heated by successive passes.
After the seed crystal (14) comes into contact with the melt (5), the single crystal silicon is pulled up without performing a necking process.
Then the stranded inner conductor (1) is rotary swaged by means of a rotary swaging device (10).
The electrodes (12a, 12b) are jointed with the outer circumferential surface of the large diameter portion by the rotary swaging process.
The striking forces are also greater than with a conventional swaging machine, and the operator must therefore be extra vigilant.
The hot swaging process is very specific in our company because the work is done in pairs with a robot!
We use hot or cold swaging processes to spread the material according to the restrictions set out in the specifications.
A projectile (20) has a boatail (24) defining a cavity (32) opened at the rear end of the boatail (24).
A recess- forming member is providing in the cap member to form a recess for receiving the recording liquid attracted from the nozzle.
A method for shrinking the exhaust volume is also disclosed.
In some versions, the connecting member comprises a recess (190; 204; 222), and the probe assembly comprises a protrusion (188; 210) configured to selectively engage the recess.
The present invention is directed to a necked laminate and a process for making the laminate.
The compositions exhibit reduced neck-in when used in extrusion coating and the neck-in is independent of melt strength, thereby facilitating improved extrusion processes.
With the new valve, laser welding of the components at a point of reduced cross-section, e.g. point 40, not only reduces the size of the valve but also gives a reliable, crack-free join.
One or more holes may be provided to allow a supply of gas to flow into the recess, and those holes optionally may be tapered such that they narrow towards the recess.
A first projection or recess is formed in the protective cap, and a second projection or recess is formed in the piercing instrument.
The tapered bore of the pilot tip is swaged with a gas inlet tube by application of force.
The invention is applicable to bellows with lugs fixed by swage-crimping of a closed ring.
Walls of the recess optionally may be insulated using, for example, ceramic.
In a further step, the rotary swaged stranded inner conductor (3) is enclosed with a dielectric (4).
The top portion of the container side wall has a torus above an inward necked area, and the cover has a flange shaped around the outside of the torus and extending into the necked area.
The rocking member or resilient arm may bias the protrusion to enter the recess.
