Abstract: An electroplating system has a vessel assembly holding an electrolyte. A weir thief electrode assembly in the vessel assembly includes a plenum inside of a weir frame. The plenum divided into at least a first, a second and a third virtual thief electrode segment. A plurality of spaced apart openings through the weir frame lead out of the plenum. A weir ring is attached to the weir frame and guides flow of current during electroplating. The electroplating system provides process determined radial and circumferential current density control and does not require changing hardware components during set up.

Intermediate bodies and joints can be provided in certain surgical tool assemblies and architectures.

Abstract: Disclosed herein are organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).

Abstract: Disclosed herein are novel drug carriers including a non-aqueous pH dependent release system and a non-aqueous pH dependent reassembly/assembly and reabsorption/absorption system.

Abstract: Surgical tools and assemblies are employed for use in minimally invasive surgical (MIS) procedures. A handheld surgical tool assembly includes a handle assembly and a frame assembly, among other possible components. Intermediate bodies and joints are provided in certain handheld surgical tool assemblies and architectures. A yaw rotational degree of freedom is furnished between certain intermediate bodies, and a pitch rotational degree of freedom is furnished between certain intermediate bodies. Amid use, a mechanical advantage generated about the yaw rotational degree of freedom is unequal to a mechanical advantage generated about the pitch rotational degree of freedom.

Abstract: A metal ionic antimicrobial surface configured for external use on a surface location in an indoor environment. A surface structure includes a pair of opposed major surfaces, one surface forming an exposed layer having a pattern of conductive strips and corresponding insulative spacings with a power pod structure secured to the surface structure. The power pod structure houses a battery and a power control circuit electrically connected to the conductive strips. In embodiments, the battery has an amp-hour capacity of 150-1500 mAh, an average width of each conductive strip of copper and silver metallic ions and each insulative spacing is between 0.1 to 0.5 millimeters, and the power control circuit includes a voltage booster circuit that maintains a constant low voltage of 2.5V-4.5V.

Abstract: A method may comprise: exposing a substituted chromone dissolved in a solvent to a sample; taking a fluorescence measurement of the sample after exposure to the substituted chromone; and determining a presence or absence of one or more ions in the sample, a concentration of the one or more ions in the sample, or both based on the fluorescence measurement.

Abstract: A feeding system for feeding individual animals of a herd feed, supplements, and combinations thereof. The feeding system includes one-to-many feed bin assemblies or feeding stations such that the system is able to dispense a specified mass of feed to specific animals at user-defined intervals. In this way, each animal of a herd is provided with optimal, individualized amounts of feed or feed material. Multiple feed bin assemblies in a single pasture, for example, can automatically form a network of feeders so that regardless of the specific feed bin assembly or feeding station within the feeding system that an animal visits, the specified amount and type of feed or feed material is delivered. Each feed bin assembly or feeding station can also be equipped to download, archive/store, and/or synthesize data into an individual animal record and/or to transmit data from additional onboard animal sensors such as activity and rumination sensors.

Abstract: A surgical instrument for applying a rotational force to a structural element during a surgical procedure. The instrument may be designed for increasing an input force to produce an enlarged output force adequate for fracturing an excess section of the elongated element from a remainder of the structural element. The instrument may include an input mechanism that receives an external rotational input force, a planetary gear system that multiples the input force, and an output mechanism that attaches to and delivers the multiplied rotational output force to the excess section of the structural element. The output mechanism may also be configured to capture the separated excess section. The instrument may include a housing and a handle for grasping and manipulating during the surgical procedure.

Abstract: A process and apparatus are disclosed for hydrocracking a hydrocarbon feed in a hydrocracking unit and hydrotreating a vaporous hydrocracked stream. The hydrotreated effluent stream can be separated and stripped to produce a ULSD stream fit for storage without further processing. The hydrocracked liquid stream can be stripped and fractionated to produce a diesel stream that can be transported to the hydrotreating unit.

Abstract: A livestock feed system adapted to be modular and readily scalable from one bin assembly to multiple bin assemblies that can be communicatively networked together. The system includes a stainless steel feed bin with an opening on a first surface of the one or more sidewalls for receiving an animal head. The feed bin further includes an access door on a second surface of the one or more sidewalls that is pivotally, slidably, or removably coupled to adjacent portions of the one or more sidewalls to allow easy cleaning of the bin. The system includes a portable support frame supporting the feed bin, and a controller mounted on the support frame. The controller includes a self-contained computer with a processor executing code (programs or software) to provide an animal monitoring and management module that causes the controller to determine intake by an animal accessing the feed bin through the opening.

Abstract: Processes and apparatuses are disclosed for removing heavy polynuclear aromatic compounds from a hydrocracked stream comprising passing at least a portion of the hydrocracked stream to a fractionation column to provide a plurality of fractionator product streams and a fractionator bottoms stream comprising unconverted hydrocarbons. A first stream and a second stream are taken from the fractionator bottoms stream. The first stream is passed through a heavy polynuclear aromatic adsorption zone to obtain a treated bottoms stream having a reduced concentration of heavy polynuclear aromatic compounds. The second stream is bypassed around the heavy polynuclear aromatic adsorption zone. Finally, the treated bottoms stream and the bypassed second stream are hydrocracked.
