Abstract: A system monitors the stability of fats and oils especially having the capacity of simultaneous analysis of a multitude of samples making it convenient for use to monitor a production plant. A plurality of probes (made from a metal taken from a group consisting of nickel, chromium, rhodium, titanium and stainless steel) have spaced parallel electrodes immersed in a liquid carrier (deionized water) through which an effluent of heated fats or oils is bubbled. A common conductivity meter responds to signals from each of the probes, in turn, for measuring the induction time of the fats or oils samples. The instrument features a power failure recovery system that utilizes a battery-power clock, so that short duration power failures do not cause a loss of data. A long duration power failure does not cause loss of data to the point of failure, however incomplete analyses are stopped.

Abstract: Polymeric compositions having resistance to impact comprising (a) from about 50 to about 90 percent by weight of a polyamide having a number average molecular weight of at least 10,000 and (b) from about 10 to about 50 percent by weight of a maleic anhydride adduct of a hydrogenated polymer of one or more conjugated dienes or a hydrogenated copolymer of a conjugated diene and a vinyl aromatic hydrocarbon, said hydrogenated polymer or copolymer having a residual unsaturation content of from about 0.5 to about 20% of its original unsaturation content prior to hydrogenation; wherein at least 5 percent by weight of components (a) and (b) are present in the form of a graft copolymer containing at least 20 percent of polyamide. The compositions exhibit especially advantageous properties, particularly high impact strength and are useful in a variety of molding applications such as molded bushings, gears, cams, valves and a variety of other products.
