Abstract: Aspects described herein are directed to compositions, systems, and methods of manufacturing a polymer-based construction material comprising polymeric resin and filler such as calcium carbonate (CaCO3). A surface of the polymer-based construction material may be treated such that the surface energy is increased from the material's inherent value to a predetermined value of at least 40 dynes/cm2. Further, the surface energy of the treated surface may persist within 20% of the predetermined value for at least three days.

Abstract: A bulk high performance permanent magnet comprising a neodymium-iron-boron core having an outer surface, and a coercivity-enhancing element residing on at least a portion of said outer surface, with an interior portion of said neodymium-iron-boron core not having said coercivity-enhancing element therein. Also described herein is a method for producing the high-coercivity bulk permanent magnet, the method comprising: (i) depositing a coercivity-enhancing element on at least a portion of an outer surface of a neodymium-iron-boron core substrate to form a coated permanent magnet; and (ii) subjecting the coated permanent magnet to a pulse thermal process that heats said outer surface to a substantially higher temperature than an interior portion of said neodymium-iron-boron core substrate, wherein said substantially higher temperature is at least 200° C.

Abstract: The present invention provides a rear gun rest that can be attached to a stock of a firearm in a permanent fashion. The rear gun rest remains on the firearm with minimal interference with the use of the firearm. The rear gun rest includes a main tube pivotally connected to said stock. The main tube includes a pivot pin as part of the main tube, a retaining pin as part of the main tube and at least one tension spring connected between said pivot pin and said retaining pin. The pivot pin allows the pivoting of the main tube. The tension spring aids in retaining the main tube in a desired position. The rear gun rest also includes an extension tube and a fine adjustment rod for adjusting the height of the stock. The extension tube is extendible from the main tube. The fine adjustment rod is extendible from the extension tube.

Abstract: A magnet piece and armature are arranged around a circuit breaker load strap having a bimetal strip attached thereto. The magnet piece is formed in a U-shaped configuration and is attached to the load strap. A corresponding U-shaped armature is pivotally mounted to the magnet piece in a partially overlapping relation. The U-shape armature presents a larger magnet pole surface to the magnet piece for enhanced magnetic interaction.

Abstract: A selectable rating plug allows a standard molded case circuit breaker design to be used over a wide range of ampere ratings. The rating plug is used to control the thermal load on the thermally responsive trip element within the breaker. Movement of the thermally responsive element articulates the breaker trip mechanism in response to predetermined overload conditions to interrupt circuit current.

Abstract: Sampling equipment is provided for sensing and controlling the settling rate of a flocculated slurry suspension in a settling tank, the sampling equipment comprises a metering device (23) including a vertical settling chamber for repeatedly taking a sample of the suspension from the settling tank. Means (33, 35, 19) are provided for temporarily retaining the height of the sample at a preselected level during a settling period and detector means (40, 41, 42) are provided for detecting when a boundary level defined by the settling solids reaches a further preselected level. Timer means determine the actual settling period elapsing between the start of the settling period and the time when the boundary level has reached the further preselected level.
