Tube cutting

To cut tubing, you will need a cut-off saw with a steel cutting blade as listed in the tool list, and V-blocks with clamps to hold the tubing tight while cutting. A hacksaw can be used to cut the tubing, or the pieces can be cut at a machine shop. 

A bench grinder is handy to smooth out burs on the edges of cut tubing, but a hand file can also be used instead.

In one extractor (FMC Inc.), the fmit is located between two cups having sharp-edged metal tubes at their base. The upper cup descends and the many fingers on each cup mesh to express the juice as the tubes cut holes in the top and bottom of the fmit. On further compression, the rag, seeds, and juice sacs are compressed into the bottom tube between the two plugs of peel. A piston moves up inside the bottom tube forcing the juice through perforations in the tube wall. A simultaneous water spray washes the peel oil expressed during extraction away from the peel as an oil—water emulsion the peel oil is recovered separately from the emulsion. 

Use the fluid entering from twice the cross section of one tube as stated in API RP 520 (one tube cut in half exposes two cross sections at the cut). ... 

When making a seal the tungsten rod is first beaded as with Pyrex. The bead of the special glass may either be fused directly into Pyrex (Figure 38,1) or first fused into a tube of the same glass and this tube cut near to the seal and fused to a Pyrex tube (Figure 38, It). 

The dissolved substances (especially if the solution is very concentrated) often crystallises in the funnel on account of local cooling and in this way filtration is hindered. This trouble can be partially met by using a funnel (Fig. 3) with the delivery tube cut short (0 5-l-0 cm.). But it is much more satisfactory to use a so-called hot water funnel (Fig. 4) in which the filtering surface of the funnel is heated with boiling water in a metal jacket. When inflammable solvents are used, the flame must be extinguished before filtration. 

As described earlier, the RDM planned by AEA is derived from the baseline system design but has significant modifications. Tests performed to demonstrate the operability of these modifications would be done at the vendor s plant prior to shipment or during system-ization of a facility at Blue Grass. No Demo II or EDS tests were performed. Committee concerns include the reliability of tube cutting technology for this application and underlying assumptions about the impact of... 

This still needs to be evaluated. The technology provider plans to test the new RDM at the vendor s facility prior to shipment. No proof of principle prior to this time is anticipated, especially demonstration of the efficacy of the tube-cutting concept for concurrent cutting of firing tubes and contained rockets. Also, the capability of the punch-and-drain and rocket-cutting operations to prevent agent contamination of energetics has not been demonstrated. 

The release behavior of aquo-CDDP from the conjugates was investigated in PBS at 37°C in vitro. The conjugates (10 mg) were dialyzed in PBS (pH = 7.4,20 mL) containing IM NaCl using a cellulose tube (cut off =1.0... 

Dissolve the pellet in a minimal volume (approx 30 mL) of cold BBS (see Note 9). Prepare the dialysis tubing. Cut the dry tubing into strips of manageable lengths (approx 30 0 cm) (see Note 10). 

MHz) for spin decoupling and H (61 MHz) for field locking. The container for liquid samples is shown in Figure 2.5. It consists of a normal high precision 5 mm NMR tube cut to a length of 60 mm and closed with a piston and a cap made from the machinable ceramic Macor. These probes were successfully used to study solvent exchange on solvated metal ions and metal ion complexes [14, 15]. 

Pump tubing Cut 1 m of Marprene tubing, and fit a male adapter MTLI 250 into each end. Loosely attach plug R94 to each MTLI 250 for additional protection during manipulation Prepare several of these, since one is used for each hollow-fiber production unit and for the filtration circuit. 

Basic Glassworking Working with Glass Tubing Cutting glass tubing... 

Heat a 14- to 16-in. piece of 5- to 8-mm inside diameter glass tubing and pull out a constriction in the center of the tube. Cut the tube at the constriction and mount each of the 2 sections as shown in Figure 2-9. 

To Insert a Glass Tube into Rubber Tubing. —- Cut... 

From 10 mm tube cut a 15 cm length and an 8 cm length. Fire-polish both ends of the long piece and only one end of the short one. Stopper one end of the 15 cm length and mark it in the centre. After a preliminary warm up in a soft flame, heat the mark with a hot flame, about half the diameter of the tube in size, and blow up a small blister similar to that shown in Fig. 6.29a. 

To blow a 10 mm diameter bulb in a 5 mm diameter tube, cut off a 30 cm length of the tube and fire-polish the ends. Make two marks near the centre and 16 mm apart. Stopper one end with a rubber plug.
