All fasteners (nuts, bolts, etc.) and other unpainted structural elements to be 316L or 304L stainless steel depending on the application. Protective coating for structural steelwork and carbon steel or ductile cast iron plant items—to be developed. All spill containment to be 304L stainless steel. 

Tellurium—copper alloys are recommended for situations demanding a high production rate with no significant sacrifice in conductivity. These alloys can be soldered, brazed, or welded without incurring embrittlement. They are used in vacuum applications, forgings, screw-machine parts, welding-torch tips, transistor bases, semiconductor heat sinks, electrical connectors (qv), motor and switch parts, and nuts, bolts, and studs. Addition of tellurium significantly improves the surface of machined parts. 

Tighten all nuts, bolts, and screws periodically check hooks regularly— open hooks may allow mattress to fall. 

In a study of skin disease among workers at an automobile factory, 230 workers with skin disease and 66 controls were patch tested with potassium dichromate (0.175% chromium(VI)). Sensitivity to potassium dichromate was seen in 24% of the patients and 1% of the controls. Most of the sensitive patients were assemblers who handled nuts, bolts, screws, and washers, which were found to have...

Fig 38 39. Here are some pictures to help you make an easy self humidifying chamber, most things to make the chamber can be obtained from local hardware shops the plastic car registration plate nuts bolts from car accessory shops. All that is needed to keep the tank humid is an air stone some tube a small aquarium air pump, Simply make a small hole near the top of the tank feed the pipe through to the water container, attach the air brick pump. The inner angled drip lids are simply shaped 2mm plastic sheet. 

Spray the inside of the mold with a casting release agent. Hix and pour liquid casting plastic into the mold until It Is approx. I/A inch deep. Now pour in 3/16" or l/A" Steel ball bearings until you have a layer of them covering the bottom of the mold. Add casting plastic If needed so that the layer of balls is barely covered. Set Che mold a-Slde and let the plastic cure. N0T Plaster of Paris or body putty can also be used to cast the balls in. The ball bearings are the easiest to work with but any metal can be used (nuts, bolts, screws, nails, etc.).

After the bowstring Is strung.you can test the thing with a variety of ammo. Regular arrows can be used.but the feathers may need to be trimmed to fit the barrel. The best ammo to feed it Is 1/2 steel ball bearings, but you can even use nuts, bolts, marbles, etc. When shooting any kind of round ammo, cotton wadding Is tucked in to hold the pellet In place... 

Attach 1 nut (N) to 1 bolt (B) to assemble a nut-bolt (NB) model. Make as many NB models as you can. Record the number of models formed, and record which material was used up. Take the models apart. 

It is a common (and desirable) fabrication practice to supply loose nuts, bolts, and clamps and to have these fastened inside the column. 

It is a good practice to order about 10 percent spares on nuts, bolts, or clamps in case some become damaged or lost. In some fouling or corrosive services, a larger percentage of spares is often stocked. In such services, spare trays are sometimes justified in order to minimize downtime (268). 

The risk of accident due to dropping nuts, bolts, or tools must be minimized. This is most important when two or more crews are working in the column at the same time at different levels. Loose articles in the vicinity of the upper manholes must be eliminated. Ropes and cables going into the tower must be secured in place. Guideline 10 in Sec. 10.5 elaborates on the preferred practices when more than one crew works inside the column.
