Abstract: Methods are provided for improving the yield of distillate products from hydroprocessing of gas oil feedstocks, such as vacuum gas oils. It has been unexpectedly found that stripping of gases or fractionation to separate out a distillate fraction during initial hydrotreatment of a feed can provide a substantial increase in distillate yield at a desired amount of feedstock conversion. The improvement in yield of distillate products can allow a desired level of conversion to be performed on a feedstock for generating lubricating base oil products while reducing or minimizing the amount of naphtha (or lower) boiling range products. Alternatively, the improvement in yield of distillate products can correspond to an improved yield during a single pass through a reaction system, so that distillate yield is increased even though a lubricant boiling range product is not generated.

Abstract: A double-sided bonding process using transient liquid phase (TLP) bonding structure. A first side of an electronic device is processed to partially complete bonding. A second side of the electronic device is processed to complete bonding. The first side completes bonding during the processing of the second side. This reduces the time needed for the bonding process of both sides. This process allows for various TLP bonding parameters while being compatible with conventional fabrication systems.

Abstract: An method for automatically testing an arc flash detection system by periodically or continually transmitting electro-optical (EO) radiation through one or more transmission cables electro-optically coupled to respective EO radiation collectors. A test EO signal may pass through the EO radiation collector to be received by an EO sensor. An attenuation of the EO signal may be determined by comparing the intensity of the transmitted EO signal to an intensity of the received EO signal. A self-test failure may be detected if the attenuation exceeds a threshold. EO signals may be transmitted according to a particular pattern (e.g., a coded signal) to allow an arc flash detection system to distinguish the test EO radiation from EO radiation indicative of an arc flash event.
