Preparation of the Joints

First, use only enough to do the job Spread it thinly along the upper part of the joints, only. Push the joints together with a twisting motion. The joint should turn clear from one third to one half of the way down the joint. At no time should the entire joint clear This means you have too much grease and must start back at Preparation of the Joints.

The cost of circumferential welding, C , including the it of preparation of the joint, is usually expressed in ms of dollars per foot of weld and is given in Table 5.2. e fabrication cost per tarcumferential weld will be... 

Disappointing results may occur in spite of careful selection of the correct adhesive for the material in question and proper joint design if attention is not given to preparation of the joint surfaces prior to application of the glue. 

Good preparation of the joint before executing the finishing bead the underlying bead must be uniform, perfectly clean and leave 1mm from the pipe surface to permit the voluminous pool of the last bead to rest smoothly and create a 1-1.5mm seam for the widest part of the Joint. 

The author is grateful for discussions with D. E. Manolopoulos. The hospitality of the Joint Institute for Astrophysics at the University of Colorado during the final preparation of the manuscript is gratefully acknowledged. 

The authors thank Y. Oono and M. Balsera for invaluable contributions to the joint development of SMD and J. Gullingsrud for many suggestions in the preparation of the manuscript. Images of molecular systems were produced with the program VMD (Humphrey et al., 1996). This work was supported by grants from the National Institute of Health (PHS 5 P41 RR05969-04), the National Science Foundation (BIR-9318159, BIR 94-23827 (EQ)), and the Roy J. Carver Charitable Trust. 

Branch Welds These welds eliminate the purchase of tees and require no more weld metal than tees (Fig. 10-127). If the branch approaches the size of the run, careful end preparation of the branch pipe is required and the run pipe is weakened by the branch weld. See subsection Pressure Design of Metallic Components Wall Thickness for rules for reinforcement. Reinforcing pads and fittings are commercially available. Use of the fittings facilitates visual inspection of the branch weld. See subsection Welding, Brazing, or Soldering for rules for welded joints. 

Once again the first step is the adequate preparation of the surfaces to be joined. First the side arm should be prepared, as for butt-sealing two tubes, by blowing out the end (p. 59). A hole is then blown in the side of the tube at the position required (see p. 59 for details). Care should be taken not to make this hole too large. Both ends of the tube should then be blocked since it is best to blow through the side arm so that the whole joint can be seen while blowing. Some workers, however, prefer to blow through the cross-piece. 

Welding rod is employed when necessary, but if the parts are prepared satisfactorily the flares should provide sufficient glass to alleviate the need for rod. With care it will also be unnecessary to hold the inside tube in position since only part of the joint is heated to... 

The only difference between this type of joint and a normal butt joint is in the preparation of the capillary tube first the end of this is sealed off and a small fairly thin-wall bulb btown equal in diameter to the hole in the wide tube. The end of this bulb is then blown out and the joint made by the normal method. The flame must be directed so that the capillary is not collapsed. If the capillary has a very fine bore some difficuhy will be found in blowing through it. This may be overcome by connecting it to a compressed air line while the smaU bulb is btown the end of the bulb can then be pulled out with a rod and cut off to give the prepared end. 

In this method the internal tube is in two pieces and there is less likelihood of making a joint with pinholes in it. The first step is the preparation of the internal tube a length of tubing is drawn off, the end blown out and polished smooth in the flame. The projecting part of the internal tube should be prepared in the same way. The outer tube should be prepared by closing one end to a round end.

We also express our gratitude to Pierre Potier, member of the French Academy of Sciences, President of the Foundation of Maison de la Chimie for having honored us by his presence at the opening of the Conference and his warm welcome to his "house". We also express our appreciation to Pascale Briand, who was the joint Director of Ecole Normale Supdrieure for Sciences during the preparation of the meeting, for her support and her heartening and visionary talk at the opening session. Let both receive our warmest thanks. 

The long range objectives of the joint program are the investigation and development of a concrete-polymer composite as a new construction material. The program includes the development of techniques for preparing concrete-polymer material, measurement of the physical and chemical properties, preparation of full-scale concrete products, and the conceptual design and evaluation of various specific applications. 

A 65-year-old man with bilateral osteoarthritis of the knees developed an effusion in the left knee. The swollen joint was treated with an intra-articular injection of triamcinolone hexacetonide 40 mg. The next day, he developed acute arthritis in the injected knee the joint was swollen and tender and he was unable to walk. Examination of the joint fluid showed 35 ml of a thick, turbid, yellowish synovial fluid with a leukocyte count of 13 x 106/1 (95% neutrophils). Gram and acridine orange stains were negative. Wet preparations of...

The original edition of this book, written in Chinese for students in mainland China, was published in 2001 jointly by Chinese University Press and Peking University Press. The second edition was published by Peking University Press in 2006. During the preparation of the present English edition, we took the opportunity to correct some errors and to include updated material based on the recent literature.
