A chip pretreatment process which comprises conveying the feed material through a compression screw device having an atmosphere of saturated steam at a pressure above about 5 psig, decompressing and discharging the compressed material from the screw device into a decompression region, feeding the decompressed material from the decompression region into a fiberizing device, such as a low intensity disc refiner, where at least about 30 percent of the fiber bundles and fibers are axially separated, without substantial fibrillation of the fibers. Preferably, the fibers are axially separated with less than about 5 percent fibrillation, and subsequently the fiberized material is refined in a high intensity disc refiner until at least about 90 percent of the fibers are fibrillated. In another form the invention combines chip fiberizing with chemical treatments, for improving the pulp property versus energy relationships.

An oil separator for a compressor is shown, wherein an oil separating efficiency is maximized and a material cost, a weight, and an assembly time are minimized.

A condom having a first lubricating composition containing a male genitalia desensitizing agent on the inside surface thereof and a second lubricating composition on the outside surface thereof. The first lubricating composition has a higher viscosity than the second lubricating composition so that the first lubricating composition remains on the inside surface of the condom during packaging, shipping, storage, and use.

A radiation therapy system optimized for treating extremities such as the breast has unique geometrical features that enable the system to deliver an accurately located prescribed dose to a target volume while eliminating or reducing the collateral dose delivered to the rest of the patient. The patient lies in a prone position on a rotating, shielded table, with the anatomy to be treated protruding through an orifice in the table into the path of a radiation beam. An optional integral imaging system provides accurate target volume localization for each treatment session. Utilizing the effects of gravity on a prone patient maximizes the separation of a target volume within the breast to adjacent critical structures such as the chest wall, heart and lungs, thereby reducing long term complications not associated with the primary disease. A shielded interface surface between the radiation source and the patient reduces patient dose due to scattered or stray radiation. A shielded enclosure for the radiation sources combined with the shielded interface surface eliminates the need for primary shielding in the room and allows the therapy system to be used in a transportable, mobile facility.

The present disclosure relates to a medical catheter including an elongate catheter member defining a longitudinal axis and having a proximal end, a distal end, an outer wall, and first and second internal lumens. The outer wall of the catheter member includes a first opening in fluid communication with the first internal lumen to facilitate the establishment of a first flow stream, and a second opening in fluid communication with the second internal lumen to facilitate the establishment of a second flow stream. Each of the first and second openings includes proximal and distal tapered portions that are connected by an intermediate portion having a constant transverse dimension. The configurations, dimensions, and positioning of the first and second openings optimizes separation of the first flow stream from the second flow stream in order to reduce the likelihood of recirculation between the first and second internal lumens.

We describe a switch mode power supply having a power input, a switch, a transformer, and a power output. The transformer has a primary winding coupled to said power input via said switch, and a secondary winding coupled to said power output. The transformer further comprises an auxiliary winding and a coupling structure capacitatively coupled to said secondary winding of said transformer; wherein said coupling structure does not comprise a shield or screen between said primary and secondary windings. The switch mode power supply further comprises a coupling capacitor connected between said coupling structure and said auxiliary winding to provide a noise suppression voltage from said auxiliary winding to said secondary winding to at least partially cancel a common mode noise voltage on said secondary winding from unshielded coupling from said primary winding.

A memory includes a programmable resistance array with high ratio of dynamic range to drift coefficient phase change memory devices.

A cyclonic vacuum cleaner comprises a first stage 10 comprising a single cyclone separator for separating heavier dirt and dust particles and a second stage 11 comprising a plurality of cyclone separators 25 arranged in parallel in a plurality of groups, each group of cyclone separators 25 comprising a respective inlet duct 24, each inlet duct 24 being connected at its upstream end to the first stage 10 and at its downstream end to the cyclone separators 25 of its respective group.

The present invention relates to methods and systems for the analysis of the dissociation behavior of nucleic acids and the identification of determining whether a genotype is present in a biological sample. This includes methods and systems for determining whether a genotype is present in a biological sample, through generating a dynamic profile an unknown genotype, correlating the dynamic profile to an average profile for a known genotype to generate a correlation value, and determining whether the correlation value falls within an acceptable threshold to determine if the unknown genotype is the known genotype. The present invention also relates to methods and systems for generating a training set to allow a machine to recognize a known genotype from within a class of known genotypes. The training set generated by these methods and systems may be used to assist in identification of unknown genotypes.

A gasoline blending components production system useful for producing both aromatics and gasoline blending components from naphtha. The production system includes a light hydrocracked naphtha splitter, a medium hydrocracked naphtha splitter, a naphtha hydrotreater, an isomerization unit, a continuous catalytic reformer and aromatics complex. The production system is operable to produce both refined benzene and para-xylene products in addition to medium hydrocracked naphtha, isomerate, a C7s cut and a C9+ cut, which are useful for gasoline blending without additional treatment. A method for producing gasoline blending components while maximizing aromatic production includes introducing both stabilized hydrocracked naphtha to the light hydrocracked naphtha splitter and straight run naphtha to the naphtha hydrotreater. Operating the production system produces three types of hydrocracked naphtha: a light hydrocracked naphtha, a medium hydrocracked naphtha and a heavy hydrocracked naphtha. Light and heavy hydrocracked naphtha are directed to the naphtha hydrotreater.

The subject disclosure presents systems and computer-implemented methods for providing reliable risk stratification for early-stage cancer patients by predicting a recurrence risk of the patient and to categorize the patient into a high or low risk group. A series of slides depicting serial sections of cancerous tissue are automatically analyzed by a digital pathology system, a score for the sections is calculated, and a Cox proportional hazards regression model is used to stratify the patient into a low or high risk group. The Cox proportional hazards regression model may be used to determine a whole-slide scoring algorithm based on training data comprising survival data for a plurality of patients and their respective tissue sections. The coefficients may differ based on different types of image analysis operations applied to either whole-tumor regions or specified regions within a slide.
