Abstract: A hard hat, including a hat base having a shell, a reservoir disposed within at least a portion of the hat base to store at least one liquid therein, a distribution system disposed within at least a portion of the hat base, the distribution system including an electric pump connected to the reservoir to extract the at least one liquid from the reservoir, and a flexible conduit disposed at a first end on at least a portion of the reservoir and at a second end on at least a portion of the electric pump to direct the at least one liquid from the reservoir to the electric pump, and a misting unit disposed within at least a portion of the hat base to receive the at least one liquid from the distribution system and create a mist therefrom.

Abstract: A vacuum motor assembly that includes a motor comprising a drive shaft; an impeller having a plurality of impeller blades spaced radially around a center portion of the impeller. An impeller cover that forms an air channel is spaced around the impeller and the impeller cover includes a front portion; a back portion engaged to the front portion; and a back support. The drive shaft of the motor passes through the drive shaft receiving hole of the back support and engages with the impeller. A front surface of the impeller defines a vertical plane and a first air channel interior distance from the front portion inner surface to the vertical plane within the airflow channel is greater than a second air channel interior distance measured from a back portion inner surface to the same vertical plane.

Abstract: A polymer processing aid (PPA) reduces melt defects in extruded polyolefins in the absence of fluoropolymers. The polymer processing aid comprises a polyalkylene glycol such as a polyethylene glycol together with a high pressure low density polyethylene (LDPE) and reduces melt defects well in a thermoplastic polyolefin such as a linear low density polyethylene (LLDPE).

Abstract: The present application relates to metal-organic frameworks (MOFs). More specifically, the present application relates to process for their preparation and uses thereof. The present application includes a process for preparing a chromium (III) phosphonate metal-organic framework (MOF) comprising: a) dehydrating a hydrogen-bonded metal-organic framework (HMOF) comprising chromium (III) hydrogen bonded to one or more organic polyphosphonate molecule by heating the HMOF at a controlled rate; b) cooling the dehydrated HMOF from a) to provide the MOF.

Abstract: A polymer processing aid (PPA) reduces melt defects in extruded polyolefins in the absence of fluoropolymers. The polymer processing aid comprises a block copolymer having polyamide blocks and polyether blocks and reduces melt defects well in a thermoplastic polyolefin such as a linear low density polyethylene (LLDPE).

Abstract: A biaxially oriented polyethylene film structure comprises at least three layers, including a core layer, wherein the core layer comprises: i) from 50 to 99.5 weight percent of a first polyethylene which is an ethylene copolymer having a density of greater than 0.940 g/cm3: and ii) from 0.5 to 50 weight percent of a second polyethylene which is a polyethylene homopolymer composition having a density of at least 0.950 g/cm3: wherein the polyethylene homopolymer composition further comprises a nucleating agent or a mixture of nucleating agents. The biaxially oriented film has very good optical properties.

Abstract: The present invention relates to a dry blend one-part pre-flush and spacer package for forming a water-based pre-flush and spacer on-the-fly for use in a subterranean well and a method of mixing a pre-flush and spacer on-the-fly for use in a subterranean well. The dry blend pre-flush and spacer package includes an anionic surfactant, a builder compound, and optionally, a defoamer, a dispersant calcium chelator, a density modifying agent, a viscosifying agent such as a solid, and preferably rapidly hydrating, gellant, salt and one or more lost-circulation materials. The dry blend pre-flush and spacer package is mixed on-the-fly with water at the subterranean well site to form the pre-flush and spacer at a pre-selected density and the pre-flush and spacer, when pumped into the subterranean well by a pressure pumper, converts the well from an oil-wet or substantially non-water-wet condition to a substantially water-wet condition.

Abstract: A hard hat having an integral misting system for directing a liquid from a stored reservoir onto a user's face and head as a cooling mist. The misting hard hat includes a hat base having a rigid shell and suspension system, a fluid reservoir attached to the interior of the rigid shell, a misting component for dispersing liquid as a mist, and a distribution system for delivering liquid from the from the reservoir to the misting component under pressure. In one embodiment, the misting component is formed from a clip on housing that includes a plurality of misting nozzles which each direct mist from a slightly different position and/or at a slightly different trajectory, thereby provided a large coverage area for mist.

Abstract: The present invention provides a gel composition intended for use as a drug delivery device, particularly for use in the sinus cavity. The gel composition can include a gelling agent that includes at least one polysaccharide, a propellant in the form of a sterile gas, and optionally, at least one active ingredient. The polysaccharide can be selected from the group consisting of hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, carrageenans, and combinations thereof.
