In a still greater number of mines, the dust produced during leading and transportation is not being allayed effectively.

The increased body temperature leads to in creased cell metabolism, and in turn to still greater heat production.

These deposits all re tard heat transfer and so tend to pro duce a high temperature in the tube walls, leading in turn to overheating or corrosion or both.

This new information was based on work done by the Titanium Pigment Corporation, a subsidiary of Rational Lead Company.

In other words, it would be unreasonable to expect the Bureau to endorse Aroclor or any other E.P. lubrloating agent which may be regarded as being safe or relatively safe for the subject purpose as such endorsement would easily lead to complications rela tive to the position of competitive manufacturers of such agents.

The exact equivalent length of the various fittings cannot now be determined since the pipe sizes of the building main, riser, and branch leading to the highest fixture are not known as yet, but a first approximation is necessary in order to make a tentative selection of pipe sizes.

, Supply Mains: The pipes through which the heating medium flows from the boiler or source of supply to the run-outs and risers leading to the heating units.

A comparison between the performance of two designs,, unless based on such tests on each, may lead to entirely erroneous conclusions.

The material presented leads to an illustrative procedure for a cooling-load calculation, and a numerical example is given to demonstrate the calculations involved.

The oil industry is trying to solve this problem, which is now apparently becoming a serious one, and the idea that they are taking up is that of using either tetramethyl lead itself or a mixture of TML and TEL.

The tempe-ature of the "Dow Them" was noted to be 600F which leads to the conclusion that final drying is conducted at this temperature.

The inadequate blood supply and oxygen deficiency may lead to tissue death , or gangrene.
