The holder has a guide frame at the first side and a support frame at the second side. The guide frame has a first bottom surface and the support frame has a second bottom surface. The first and second bottom surfaces are vertically offset from each other. The grinding wheel has an axle supported by the guide frame and the support frame. The grinding wheel has a grinding surface located below the first bottom surface and above the second bottom surface.

Abstract: An improved pallet that is easy to assemble and disassemble. In particular, the pallet includes a plurality of stringers with bores, a plurality of deck boards with openings, and a plurality of dowels that attach the stringers and boards at an acute angle. The dowels can have protruding portions for aligning with dimples in the bottoms of neighboring pallets, thus vertically orienting stacked pallets with respect to each other, for efficient and secure stacking of the pallets. The protruding portions can be configured so as to deflect random blows and to minimize damage to the pallets when stacked. The dowels can also be positioned so as to reduce the likelihood of stress fractures to the pallets when the pallets sustain potentially damaging forces.

Abstract: Hydrocarbon processing systems and a method for liquefied natural gas (LNG) production are described herein. The hydrocarbon processing system includes a fluorocarbon refrigeration system configured to cool a natural gas to produce LNG using a mixed fluorocarbon refrigerant and a nitrogen rejection unit (NRU) configured to remove nitrogen from the LNG.

Abstract: A system and apparatus for interrupting the life cycle of sperm includes a seat upon which a user sits in a coupling position on the seat. The seat includes one or more acoustic transducers that are driven by a controller to emit acoustic waves to a region of the user's anatomy responsible for producing sperm. The user is subjected to the acoustic waves such that sperm in the user are rendered immotile.

Abstract: In various examples, a system comprises a first plurality of power supplies comprising a first plurality of external electrical connectors, and a second plurality of power supplies comprising a second plurality of external electrical connectors. The first plurality of power supplies may be symmetric with the second plurality of power supply about an axis of symmetry. The system further comprises a common fan module. The common fan module comprises a fan to cool the first plurality of power supplies and the second plurality of power supplies, a power inlet, a third plurality of electrical connectors, a fourth plurality of electrical connectors. The third plurality of electrical connectors are capable of being electrically coupled to the first plurality of electrical connectors, and the fourth plurality of electrical connectors are capable of being electrically coupled to the second plurality of electrical connectors.

Abstract: A method of interrupting the life cycle of sperm that includes subjecting a user to a first and a second treatment session in a male birth-control cycle. The first treatment session including a mature-sperm inhibition step of emitting, through at least one transducer, an amount energy for a predetermined period of time that is directed to the entire male reproductive system including but not limited to at least one of an epididymal tubules and an ejaculation ducts of the user, via a constant coupling configuration of the transducer with the user, to render a plurality of sperm transported therein to be immotile. The second treatment session includes subjecting the user to the mature-sperm inhibition step before a sperm-maturation time whereby sperm carried by the user are in a mature state.

Abstract: A sealing assembly has an expansion band having an arcuate band portion and a pair of threaded end portions formed at opposing ends of the arcuate band, in which the arcuate band and threaded end portions are monolithically formed as a single piece. Fixed within respective threaded end portions are a pair of oppositely threaded nuts adapted to receive a bolt having correspondingly oppositely threaded ends. Rotation of the bolt causes the threaded end portions to be simultaneously driven apart or drawn toward one another (depending on the rotation direction of the bolt) to thereby expand or contract the overall outer profile of the arcuate band portion. The monolithically formed expansion band may be made of an inexpensive, non-rusting material such as nylon 66, and glass fibers and/or additives may be employed to impart strength and flexibility.

Abstract: An embodiment of the present disclosure provides a compression seal configured to be disposed about a pipe. The compression seal includes a cylindrical body made of a resilient material. The cylindrical body includes a hollow bore extending a longitudinal extent of the cylindrical body, and inner and outer surfaces. The inner cylindrical surface faces the hollow bore. The outer surface is located on the cylindrical body opposite the inner cylindrical surface. The cylindrical body also includes primary and secondary lobes. The primary and secondary lobes extend longitudinally as at least part of the outer surface of the cylindrical body. The primary lobe also has an inclined plane surface. This inclined plane surface of the primary lobe ascends in a direction away from the secondary lobe.

Abstract: Described are methods for the high-throughput discovery and genotyping of nucleotide polymorphisms in DNA, including single nucleotide polymorphism (SNPs) and short deletions and insertions. These methods take advantage of the fact that differences in DNA sequence result in the differential presence of restriction endonuclease digestion sites. Approaches involve isolation of short DNA fragments (“tags”) near restriction endonuclease sites. The presence of one (or two) of these tags indicates that a site was present. Regions of DNA with a restriction site in only one individual create an opportunity for primer extension to produce labeled material, which can be assayed on a platform that employs a collection of nucleic acids. Efficient variant detection microarrays and bead libraries are provided that contain genomic tags with different representations between two populations, so that most elements in the collection of nucleic acids contain a SNP between populations of interest.

Abstract: The present techniques are directed to a flexible liquefied natural gas (LNG) plant that may be tied to an external electric grid for importing or exporting electric power. Exemplary embodiments provide a method for producing LNG that includes producing a base load capacity of refrigeration capacity for LNG production from a first compression system. Electricity may be produced from a second compressor string if electricity is needed by an external power grid, or a second amount of refrigeration capacity may be provided by the second compressor string is natural gas feed is available and the external grid does not need power.
