Tape looping

If further resolution is necessary one-third octave filters can be used but the number of required measurements is most unwieldy. It may be necessary to record the noise onto tape loops for the repeated re-analysis that is necessary. One-third octave filters are commonly used for building acoustics, and narrow-band real-time analysis can be employed. This is the fastest of the methods and is the most suitable for transient noises. Narrow-band analysis uses a VDU to show the graphical results of the fast Fourier transform and can also display octave or one-third octave bar graphs. 

Attach one tape loop to each balloon. On the pear-shaped balloons, put the tape on the end opposite where the knot is tied. 

Push two of the round balloons together so that the tape loop on each balloon sticks to the other balloon, as shown in Figure A. This is a model of the hydrogen molecule, H2. Describe the shape of the model in Data Table 1. 

Somatovisceral reflexes produce unmeasured changes on the internal organs. Sympathetic stimulation may promote or maintain a disease process. Relief of this source, if performed early enough, should alleviate the symptoms and the disease process. The viscerosomatic reflex is less amenable to cure. Manipulating the affected soma should have a beneficial effect in reducing symptoms, but the overall effect on the visceral component is indeterminable at this time. If we postulate a "tape loop" that promotes the whole process, then anything that breaks the cycle is of importance. 

Fibers. Polypropylene fibers are extensively used in carpeting. Bulked continuous filament yams are commonly used in carpet facing in the level loop carpets used in commercial buildings however, nylon remains the dominant face yam in tufted household carpets. The advantages of polypropylene carpeting are superior stain resistance and low moisture absorbance. Polypropylene sHt tape fibers are heavily used in carpet backing. 

A loop tack (Fig. 2c) test consists of allowing a tear-shaped loop of conditioned tape to drape into contact with a test surface of specified area (usually 25.4 x 25.4 mm), with the force of contact limited to the weight of the tape itself (ASTM Ref. D-6195). The ends of the loop are held in a tensile tester. After a momentary contact time the tester is engaged and the tape is removed at a specified speed. The maximum in the removal force is ordinarily observed just at the point where the two peel fronts Join. The value is reported in a force per area of tape width, or lb in. -. While this tack test has some popularity, it is perhaps more of a very short dwell time peel test, and it has variables more associated with that test, especially backing effects, since heavier backings lead to higher tack values. 

Pressure-sensitive adhesives (PSAs) based on acrylic, natural rubber and silicone are employed primarily for ease of application. To name Just a few applications, PSAs bond decals to surfaces, interior decorative surfaces to interior panels, interior trim pieces in place directly or hook and loop tape for the same purpose, structural shims in place during manufacturing and acoustic (sound deadening) materials to body skin interior surfaces. Tape products with pressure-sensitive adhesive on one or both surfaces are used for such functions as cargo compartment sealing, as a fluid barrier to prevent spills and leaks in the lavatories and... 

An extension I of I to PCS) is called "useful" if either is infinite and t, = Pj or Pj is finite and t, = p -t for some tape t thus tj is a record of the pushdown store contents of the machine executing (S,I). Otherwise I is "useless". The scheme PCS) is built to loop whenever I is "useless" so that we need only consider the effect of useful free interpretations of PCS). ... 

Fig 19. Here we see 4 bags that have had their supports added, it can be helpful to stand them in some kind of container, this will make things easier for you to prepare inoculate them, it also makes sense at this point to add tape to the inoculation points, 1 on each side of the bag 2 inoculation Points per bag this piece of tape stops the hole from enlarging upon inoculation an additional piece of tape is placed looped back, so that when you have inoculated the bag, you can quickly roll the tape down over the hole as you remove the needle from the bag. 

Filter Stick. A typical filter stick for solution filtration is shown in Figure 4. A section of teflon tubing (2-3 ft) is pushed over the Luer fitting of an observation port (Popper Sons), and conventional filter paper is then attached to the end of the observation port as shown. Half inch teflon sealing tape (Aldrich - this may also be available from a local plumbers supplier as pipe dope) is first wrapped around the base of the observation port, filter paper is then wrapped around the outside of the teflon tape, and one or two loops of nichrome wire (20 gauge, 32 thou) are used to secure the filter paper in place. The teflon tape provides a bed into which the wire can bite and seal the system. Any filter paper may be used, but we have found water resistant fine filter papers such as Whatman s 50 to be most satisfactory, except for gummy solids which may require a faster paper. 

On a length of leg wire twist on uninsulated loop around the leg wire hanging above the weight Thread other end through other uninsulated loop and fasten to top clamp. Tape wire to window weight Test circuit with galovonnKter first, then insert batteries between brackets. 

Insulate inside of case from contact with loop with friction tape. 

Schedule 40, 347 SS, 4-inch pipe, a 500-gallon-per-minute sodium pump, a corrosion test section, and a 35-gallon expansion tank. Each and every part was electropolished, pipe ends were taped dust-tight before welding, inert arc gas back welds were made, and every effort was made to complete, in the field, a chemically clean sodium system. Figure 22 shows the dirty sodium surface which resulted after clean sodium was filled into the loop. This experience demonstrated very conclusively the importance of being practical in sodium system construction. 

Nylon fibers are used to make hook-and-loop fastener tape. 

The discovery of nylon is another example of an accidental discovery. In 1930, Julian Hill, an employee of E.I. DuPont de Nemours and Company, dipped a hot glass rod in a mixture of solutions and unexpectedly pulled out long fibers similar to those shown in Figure 1.16. Hill and his colleagues pursued the development of these fibers as a synthetic silk that could withstand high temperatures. They eventually developed nylon in 1934. During World War II, nylon was used as a replacement for silk in parachutes. Today, nylon is used extensively in textiles and some kinds of plastics. It is also used to make hook-and-loop tape, as shown in Figure 1.16. 

For each balloon, make a loop of tape by wrapping the tape around two fingers. The adhesive side of the tape should face out. 

Velcro now has an amazing array of uses. On each space shuttle, there are ten thousand inches of Velcro tape it s made of Teflon loops, polyester hooks, and glass backing. Inside the helmet of each astronaut is a small Velcro patch — it serves as a nose scratcher during space walks. Manufacturers have... 

COLOSSUS was not strictly a stored program machine for the program was set by wiring plug-boards. The machine contained over 1500 thermionic valves (vacuum tubes), and it surprised everyone by its reliability and speed. It did not hold its data internally either, but on a loop of paper tape that was reread as necessary. Although the secrecy, required by the state for security...
