摘要:
An apparatus and method for the installation and removal of permanent magnets in a permanent magnet electromechanical machine, for example a wind turbine power unit generator. A magnet holder is mounted on a magnet carrying structure such as a rotor. Permanent magnets may be inserted into and removed from the magnet holder after the electromechanical machine is assembled. In this manner, permanent magnets may be installed on the magnet carrying structure by an interference fit, without using bolts or adhesives, to facilitate both assembly and removal for maintenance and repair.

A water-based concrete or masonry sealant includes an acrylic- or silicone-modified reaction product of an unsaturated drying oil and an alkyd, the reaction product being dispersed in aqueous solution; and a dispersion of metal salt catalyst in aqueous solution. A method of treating a previously sealed concrete or masonry substrate, includes the steps of applying to the previously sealed concrete or masonry substrate a sealant comprising an acrylic- or silicone-modified reaction product of an unsaturated drying oil and an alkyd, the reaction product being dispersed in aqueous solution; an aqueous dispersion of metal salt catalyst, and water; and allowing the sealant to cure.

The disclosure relates to a composition, comprising: (a) at least one organohydrocarbyloxysilane represented by the formula wherein R1, R2 and R3 are independently hydrocarbyl groups containing from 1 to about 8 carbon atoms, and R4 is a hydrocarbyl group containing from 1 to about 22 carbon atoms; and (b) at least one polymer derived from styrene and/or at least one styrene derivative, and at least one comonomer comprising one or more of acrylic acid, (meth)acrylic acid, acrylonitrile, and/or at least one alkyl (meth)acrylate. In one embodiment, the composition further comprises (c) at least one fluid, the organohydrocarbyloxysilane (a) and polymer (b) being dispersed in the fluid. This composition may be used for treating concrete surfaces.

A communication system can utilize a STANAG 5066 profile and include a data rate link mechanism. The data rate link mechanism can reside in a linking layer, such as, a subnetwork management sublayer according to the STANAG 5066 application. The mechanism allows data rate change functions of HF messages to increase throughput upon link establishment. Link quality can be determined by LQA signals generated according to MIL-STD-188-141B profiles.

A refill is provided that is packaged in a recyclable assembly of recyclable plastic and recyclable paper or cardboard. The refill is further constructed from recyclable plastic and uses soy resins for the ink. On a barrel of the ink refill is a graduated scale indicative of the amount of writeout of ink remaining in the pen. In addition, a follower, such as a floating ball or chemical chaser, clearly identifies the level of ink remaining in the refill. The assembly may further include a scale corresponding to the scale on the refill and may further include information relating to the recyclability utilization of the assembly and refill.
摘要:
A packaging card holding a device, such as a refill for a pen, and a method for packaging such a device are provided. The card has a front panel, a center panel and a back panel. The center panel may be transposed with respect to the front panel and the back panel. The center panel includes information related to the device on the card. The center panel may be rotatable or may be transposed parallel to or perpendicular to lengths of the front panel and the back panel. Preferably, each of the front panel and the back panel have an aligned aperture for suspending the card from, for example, a display hook.
摘要:
A water-reducible curing and sealing compound for coating concrete substrates is formed by combining a water-soluble salt of an acrylic polymer resin with an alkanolamine. The resulting compound is low in volatile organic compounds (VOC) and achieves the appearance and performance characteristics of traditional curing and sealing compounds containing petroleum-based solvents. In particular, the compound comprises a polymer resin that comprises three monomers, namely a vinyl aromatic monomer, an ester of acrylic or methacrylic acid, and acrylic or methacrylic acid, in a water-miscible solvent; an alkanolamine; and water.
摘要:
A pressurized refill and a method for pressurizing a refill are provided. The refill has a plug secured at an end of the refill having multiple seals between the plug and an interior wall of the refill. A valve extends through a channel of the plug allowing pressurized gas to be forced into an interior of the refill to pressurize or re-pressurize the interior of the refill. A spring loaded stem maintains the valve in a closed and sealed position when pressurization is not being effected.

A pressurized refill and a method for pressurizing a refill are provided. The refill has a plug secured at an end of the refill having at least one seal and preferably two seals between the plug and an interior wall of the refill. A valve extends through a channel of the plug allowing pressurized gas to be forced into an interior of the refill to pressurize or re-pressurize the interior of the refill. A spring loaded stem maintains the valve in a closed and sealed position when pressurization is not being effected.

A method for allowing independent viewing of web conference content may include enumerating a plurality of windows of content of a web conference to allow caching of visible and non-visible portions of each enumerated window by a client computer device of a participant to provide independent viewing of each enumerated window by the participant in the web conference. The method may also include forming a bitmap of visible and non-visible portions of each enumerated window. The method may further include transmitting the bitmap of each enumerated window to the client computer device of the participant in the web conference.
