Comparative laboratory performance of air brake cylinder lubricants

A test method for measuring the low temperature release time and the high temperature cup we ar preventive properties of air brake cylinder lubricants is described. The results of comparative trials of reference and various proprietary lubrlcants are given. Again, a non- soap thickened polyglycol grease containing MoS2 was best at 150°F. ...

The performance of prorietary and AAR specification brake cylinder lubricants at 150ºF. and -50ºF.

The performance of AAR Specification 914 -42 and 914 - 62 and proprietary lubricants , in IQ - in. air brake cylinders, was compared at 150°F . and at - 50°F. A proprietary non- soap thickened polyglycol grease, containing MoS2, was best in endurance tests at 150° F. and in piston release time comparisons at - 50°F . AAR 914 -42 Specification...

n-Decanoic acid as a vapour space inhibitor for turbine steam oils

Previous work has shown that n- decanoic acid is a potentially good vapour phase corrosion inhibitor. The effects of the addition of 0.05 and 0 .10 percent of the acid on the other proper ties of steam turbine oils have been further studi ed. It is concluded that Total Acid Numbers are increased , foaming characteristics are changed and the load...
