Even when the time comes to make a purchasing decision, an energy-efficient motor purchase is not a certainty. Sometimes an energy-efficient motor will be the economically efficient choice at other times, not. The capital investment decision is based on the cost in relation to performance, efficiency and reliability. Moreover, the decision depends on the application and the amount of time the motor is in operation. It can be the major component of a product (drill or mixer), or a minor component (computer disk drive) it can be the major component cost of a product (fan), or it can be a minor component cost (stereo tape deck) it can run almost constantly (fan, pump, and machinery), or only a few minutes a day (vacuums and power tools). For example, contractors purchase circular saws almost solely based on performance and reliability. Time is money, and since the saw is operating only a few minutes a day and the contractor is often not responsible for the electricity costs to run the motor, energy efficiency is not a consideration performance and reliability are what matter most. On the other hand, an industrial user, who runs huge electric motors twenty-four hours a day to work pumps, machinery, and ventilation equipment, is very concerned tvitli energy efficiency as well as performance and reliability. 

The main applications of coated cemented carbides are tips and blanks, indexable inserts, milling tools, turning, and boring tools and circular saws. 

Bovine lower jaws were obtained from a local slaughterhouse. Teeth were extracted, adherent soft tissue was removed with a scalpel, and the teeth were incubated in a sodium hypochlorite solution (technical grade) for 2-3 hours. The tooth crowns and roots were separated with a water-cooled circular saw and the roots were kept in tapwater at 4°C until further use.

After cotton has been harvested, the seeds must be removed. Essentially the same method devised by Whitney in 1793 is used. The seed cotton is fed into a gin consisting of a series of circular saws that separate the fiber from the seeds. The fiber is then compressed into bales weighing about 478 lb (217 kg). A second ginning separates out the short fibers leaving the more desirable longer fibers. 

Blades are tensioned. In this process the metal a little back from the tip is stretched thus allowing the blade to run straight when centrifugal forces (with circular saws) and the heating of the teeth cause the metal on the outer edge of the blade to expand. 

Tensioning of circular saw blades involves carefully hammering or squeezing the blade between narrow rolls in a zone about half to two-thirds of the way from the centre to the periphery so that the metal there is very slightly thinner with the metal being spread out sideways. The blade is pre-strained. However the metal in the... 

Figure 7.9. Distortion is a consequence of the release of growth stresses (Figure 6.16) on sawing. In a scragg null two circular saws cut synumetrically about the centre so it is possible to produce an undistorted central cant. Unforttmately the centre of the log has the lowest grade material maximizing recovery from the centre of the log may be less desirable than cutting round the log and accepting the distortions that arise (Haslett, 1988).

Specimen Preparation. The demolded castings were cut using a circular saw with a diamond cutting wheel to provide specimens for the various tests. 

Fig. 12. First put on the head. A number of different ones can be purchased, but for average target work the brass parallel pile head is most satisfactory. Cut the tenon on the end of the shaft by turning on a latbe, Fig. 14. If you arc careful, the head will be a drive fit and will hold securely. If the head is a bit loose, anchor it with a few ptmch taps as shown in Fig. 16. Cut the arrows to the required length and then cut the nocks. Plain nocks can be cut easily by running the shafts over a circular saw, as in Fig. 13. The nock should be across the grain. If you want more strength at the nock, insert a thin slip of fiber or plastic. Aluminum or molded-plasttc nocks are...

In the second frame of the cartoon, a brain surgeon uses a small circular saw to create an opening, a thin crack, all along the circumference of the man s head. The patient is pale and motionless. The doctor hands the medical saw to an assistant, opens the patient s cranial cavity by removing the skull cap, and then places this upper hemisphere of the skull in a bath of warm saline solution. 

Using the philosophical circular-saw of Occam s Razor to limit the entities, the Moreh-zedek or the Teacher of Righteousness can be seen as a common alchemical archetype with the dew or Bread of Life. In the same way Melchizedek, the King of Righteousness, is an archetype for the priest that manufactures the sacred bread. He provides this sacred bread to Abraham in a rite of kingship. 

Graves independent career risked all on the maintenance of reputation and he is highly respected for this. His non-fiction book The White Goddess and historical fiction novel King Jesus are prime examples of Graves straightforward semi-circular saw analysis. 

Saws, hand, jig-saw, or circular saws may be needed for trimming thicker moldings, both in TSs and TPs, where the trim is more than I mm thick. Precautions must be taken to protect workers against dust, with adequate extraction systems and wearing of masks.
