Abstract: An oil skimming water vessel having a hull and deck forming one or more interior compartments, wherein the hull comprising a bow or forward section, a mid-section, a stern or aft section, and an oil skimmer assembly, and wherein either or both of the bow or aft section constructed having a rake bottom shell. The oil skimmer assembly having first and second separated side walls (SKEG) extending vertically down from the rake bottom shell, a skimmer bottom plate extending between and affixed at the lower end sections of each of the side walls (SKEG) wherein the skimmer bottom plate having at least one discharge opening in its leading edge section, and a weir plate assembly. The rake bottom shell having at least one standpipe opening to which a standpipe attaches and extends vertically to a corresponding vessel deck opening.

Abstract: A cyclonic chamber for use in air filtration devices. The chamber includes an apex opposite a base with sidewalls extending therebetween. The cyclonic chamber is preferably parabolic in cross-section or tubular with a hemi-spherical cap. The base contains an outflow passage and a conical filter extending therefrom. An inflow passage is provided proximate the apex. The inflow and outflow passages are parallel but not aligned. The chamber interior is smooth. The smooth interior and offset relationship of the inflow and outflow passages causes air to take a cyclonic path between the inflow passage and the filter. Debris in the airstream is pushed outward—away from the filter—by centripetal force. Eddies form proximate the base. Debris escapes the airstream there, where it either remains or, depending upon the chamber's orientation relative to gravity, falls back into the airflow where it is again directed away from the filter.

Abstract: An emergency alert system and method are disclosed. The invention employs an emergency alert message, which directs end users to take some particular action like evacuating an identified geographic area. The invention further employs a geographic area message, which is based on a particular geographic area within which all persons should receive the emergency alert message. The invention utilizes an emergency alert enabled device that receives both the emergency alert message and the geographic area message. The emergency alert enabled device determines whether it is located within the geographic area of concern, and if so, presents the emergency alert message to the end user.

Abstract: An improved action for a bolt action rifle. The action includes a receiver containing a bolt; the bolt having two to three locking lugs surrounding a bolt face; and a threaded insert that joins the rifle barrel to the receiver. The insert also includes a series of locking lugs that mate with the locking lugs on the bolt. The position of the insert lugs relative to the barrel will position the bolt face relative to the barrel's chamber when the bolt is closed. Thus, the insert and barrel can properly set the rifle's headspace. The insert and receiver are preferably each provided with a locking lug, that serve to align the axes of the insert and receiver. The threads of the insert and the barrel are co-axial which serves to align the axes of the insert and barrel. Thus, assembled, the receiver, insert and barrel will be substantially co-axial.

Abstract: Disclosed in this specification is a range of push up bras. The range comprises different bra cup sizes, and offers a different amount of padding for different cup sizes in the same range. The different padding provided facilitates a better tailoring of the bra to the body type of the wearer. The padding occupies a decreasing area of the cup as the cup size increases. The centre of the padding is also gradually lowered with increasing cup size.
