Abstract: A bullet proof vest which is resistant to penetration by a 0.22 caliber projectile and includes a fabric or clothing made of polybenzoxazole polymer fibers. The vest is lighter, more comfortable to wear and exhibits better ballistic-resistant properties than traditional ballistic-resistant vests of equal weight.

Abstract: A lubricant exhibiting enhanced properties, including improved load-carrying capacity and wear reduction, includes synthetic and/or mineral oil as a major ingredient, and a performance-enhancing amount of vegetable oil. In addition to providing improved performance characteristics, the vegetable oil additive reduces the need for certain other additives, including pour point depressants and viscosity index improvers, thereby simultaneously lowering the overall cost of the lubricant.

Abstract: An inexpensive process for depositing an electrically conductive material on selected surfaces of a dielectric substrate may be advantageously employed in the manufacture of printed wiring boards having high quality, high density, fine-line circuitry, thereby allowing miniaturization of electronic components and/or increased interconnect capacity. The process may also be used for providing conductive pathways between opposite sides of a dielectric substrate and in decorative metallization applications.

Abstract: Ballistic-resistant articles comprise a plurality of polybenzoxazole or polybenzothiazole polymer fibers and are lighter, more comfortable to wear and exhibit better ballistic-resistant properties than existing ballistic-resistant articles of equal weight.

Abstract: Thin film thermal oxidative engine oil or other oleaginous liquid deposit device has an oleaginous test liquid placement volume; a heatable depositor surface in liquid communication with the volume; a supply for at least one of an oxidant and another substance which can adversely affect the test liquid; and a relatively thin film forming unit which delivers the test liquid to the depositor surface in a relatively thin film. Thin film thermal oxidative engine oil or other oleaginous fluid deposit method is also provided, which includes providing an oleaginous test liquid in an oleaginous test liquid placement volume; providing a depositor surface and heating said surface; delivering the test liquid as a relatively thin film to the heated depositor surface; providing to the test liquid an oxidizing and/or other substance which can adversely affect the test liquid; and observing any deposits or other activity thereabout. The invention is useful in oil testing.
