Abstract: Increasing the chromium content of an electrical steel substrate to a level greater than or equal to about 0.45 weight percent (wt %) produced a much improved forsterite coating having superior and more uniform coloration, thickness and adhesion. Moreover, the so-formed forsterite coating provides greater tension potentially reducing the relative importance of any secondary coating.

A second cutting profile of the second rotatable cutting structure extends only from the gage region of the earth-boring tool and to an innermost boundary of a nose region of the earth-boring tool.

Abstract: Increasing the chromium content of an electrical steel substrate to a level greater than or equal to about 0.45 weight percent (wt %) produced a much improved forsterite coating having superior and more uniform coloration, thickness and adhesion. Moreover, the so-formed forsterite coating provides greater tension potentially reducing the relative importance of any secondary coating.

Abstract: A packaging system and/or storage arrangement for limited life optical media that includes a provision to indicate the presence of oxygen and/or the amount of oxygen present. An oxygen-sensitive material is placed inside a sealable container. The oxygen-sensitive material will undergo a detectable change in the presence of oxygen and/or a detectable change occurs that will correspond to the amount of oxygen present in the sealable container. The detectable change provides an indication of the presence of oxygen and/or a measure of the amount of oxygen inside the sealable container.

Abstract: A method for dynamic service activation, including receiving a service item, including a target component and a corresponding target service level. The target component is at a current service level. It is determined if the service item can be dynamically applied to the target component. The determining is responsive to the corresponding target service level and to the current service level. The service item is applied to the target component in response to a determination that the service item can be dynamically applied to the target component. The applying is performed in a non-disruptive dynamic manner.

Abstract: There are disclosed certain novel compounds identified as benzo-fused lactams which promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to increase the stature of those afflicted with a lack of a normal secretion of natural growth hormone. Growth promoting compositions containing such benzo-fused lactams as the active ingredient thereof are also disclosed.

Abstract: A process for producing petroleum from subterranean formations is disclosed wherein production from the formation is obtained by driving a fluid from an injection well to a production well. The process involves injecting into the formation via the injection well asphaltenes as sacrificial agents to inhibit the deposition of chemical recovery agents such as surfactant on the reservoir matrix. Normally the process would be carried out by first injecting the asphaltenes into the formation through the injection well and following them with a chemical recovery agent. The chemical recovery agent would then be followed by a drive fluid such as water to push the materials to the production well.

Abstract: Apparatus and method for measuring oil flowing in a pipe include continuously sampling the cil to provide a stream of sample oil. The temperature of the sample oil is changed by a predetermined amount. The acoustical velocity of the sample oil is determined prior to the temperature change and after the temperature change by sensors providing corresponding signals. A circuit provides a signal corresponding to the water content of the oil in accordance with the acoustical velocity and the known temperature change.
