摘要:

ABSTRACTA report is presented of preliminary tests in an investigation to determine the effects of various factors in the manipulation of the autoclave for testing wall tile. The effect of porosity. pressure, duration of test, slow versus rapid release of pressure, and the number of repetitions of the test have been investigated.

摘要:

ABSTRACTThe relation of impact tests on tableware to impact properties as determined on small test pieces, breaking with transverse, shearing, and compression blows are discussed. Data are given for compression impact covering the field of china bodies. The relation of impact resistance to the elastic properties of bodies is also discussed.

摘要:

ABSTRACTA series of tests to determine the relative tensile strength of mortars containing hydrated lime and finely‐ground raw clay used as plasticizing agents have been conducted. These tests reveal no distinct ditrerence between the two materials in this respec

摘要:

ABSTRACTA lubricant for car bearings was desired which would furnish maximum protection for the bearings and decrease power consumption as much as possible. The maximum operating temperatures reached by the bearings were ascertained and a suitable lubricant compounded, effecting the desired results. A plan for using the lubricant is presented.

摘要:

ABSTRACTThe manufacture of opal glass in day tanks has made it necessary to study the corrosion of tank blocks. Opacifiers have to be used in larger quantities than in batches for opal glasses melted in covered pots because of the loss of density due to higher melting temperatures and shorter melting times, and exposure of batch to reactions from the direct flame heat.Experiments have been conducted to ascertain the factors which will allow the use of the lowest amount of opacifiers, the shortest practical melting time with the highest practical melting temperature, and also to minimize the corrosion of the bottom blocks of tanks by application of a cooling system, as well as prevention of separation of batch by practising certain “filling‐in” methods of the batch, and as a final result to reduce block stones in the glass. The experiments have resulted in the successful operation of day tanks for opal glass and in prolonging the life of the tanks, and have made possible the manufacture of thin blown dense opal glasses of almost as good quality from tanks as can be produced in
