摘要:
The present invention relates to a stud including, a first end and a second end, a torque transferring structure located at the first end, a shaft provided with an axis and including a threaded surface that is provided with a locking thread located adjacent to a Vee shaped thread, the threaded surface is dimensioned to engage a plurality of threads on a nut body, wherein the plurality of threads on the nut body are provided with a diameter greater than an M12, and the locking thread on the shaft is provided with a root surface located between a first angled surface and a second angled surface, wherein the root surface is angled relative to the axis of the shaft.
摘要:
A polyolefin composition containing elastomers (plasticizers), crystalline polypropylene, modified by mixing with polybutene-1 and a coupling agent and a bicyclic dicarboxyl acid salt nucleating agent and/or a lubricant which comprises an unsaturated fatty acid ester which acts as a surface modifier in a molded article is described. The composition is adapted to be used with pigments to make finished molded articles which have an appearance of paint covered by a clear coat and which are scratch resistant and have good low temperature (−30° C.) impact properties.
摘要:
An optical amplifier system is disclosed comprising a span of dispersion compensating fiber (DCF) and a temperature control system. The temperature control system is positioned proximate to the DCF span. The DCF span is configured to carry optical signals. The temperature control system is configured to control the temperature of the environment directly surrounding the DCF span to reduce polarization mode dispersion (PMD) fluctuation in the DCF span.
摘要:
Methods and compositions are provided for transgene expression in target cells. Expression constructs using an inducible amplification system to drive expression of a therapeutic gene or other gene of interest in mammalian host cells are provided, as well as methods therefor. Inducible expression of the transgenes at high levels under physiologic conditions results from induction by hyperthermic conditions relative to the basal temperature of the host cells.
摘要:
A bicomponent fiber wick is provided for use in processing an analyte fluid. The bicomponent fiber wick comprises a self-sustaining, fluid transmissive body comprising a plurality of bundled, crimped, bicomponent fibers bonded to each other at spaced apart contact points. Each bicomponent fiber has a fiber structure comprising a first fiber component formed from a polyamide material and a second fiber component. The fibers collectively define tortuous fluid flow paths through the fluid transmissive body, the fiber structure being configured for controlling flow of the analyte fluid through the fluid transmissive body with at least a portion of the first fiber component in contact with the analyte fluid.
摘要:
Isolated polynucleotides encoding histatin polypeptides expressed in bovine tissues, including mammary gland and paratoid salivary gland tissues, are provided, together with genetic constructs and host cells comprising such isolated polynucleotides. Methods for the use of such polynucleotides and polypeptides are also provided.
摘要:
A system and method for delivery of complete hard drive erasing software to a client computer via Internet and Windows operating systems. Hard drive erasing software is installed into a software program which simulates the booting of a floppy disk, the integrated software is subsequently installed into a software installation program and is delivered to the customer computer over a computer network by a vendor server connected to the computer network (Internet). At the customer computer, the hard drive erasing software is executed on the customer computer hard drive by executing the boot simulation software.
摘要:
A trimmer head for use with rotary vegetation cutting devices is disclosed. The head has a wear guide that indicates when the body of the trimmer head is worn down and needs replacement. In an embodiment of the invention, the body comprises two plates that are molded to fit together. The plates have bores for holding connecting pins. The connecting pins not only hold the plates together, but also pivotably support cutting blades, by fitting into openings in the blades.
