Embodiments of the invention comprise methods and systems for optimizing coagulant dosing of raw water in a water treatment process. First, the embodiments determine the optimum dosage of pH adjusting chemicals to be added to the raw water based on a measurement of dissolved organic content, alkalinity, and pH of the raw water. Then, the embodiments perform a flocculation test of a mixture of the optimally-pH-dosed raw water and a hydrolyzing metal salt (HMS) wherein the dosage of the HMS salt in the mixture can be calculated based on a measurement of the charge demand of the optimally-pH-dosed raw water. The results of this flocculation test are compared to the results of at least one previous test of a combination of optimally-pH-dosed raw water and HMS to determine if the hydrolyzing metal salt dose is optimized. Once the HMS is optimized, the optimally-HMS-dosed optimally-pH-dosed water is tested with at least two different dosages of a polymer coagulant to determine the optimal polymer coagulant dosage to be used with the optimally-HMS-dosed optimally-pH-dosed water.

A wheel for a bicycle, or other human powerable vehicle, has a hub that includes: (a) an axle for attachment to a bicycle frame; (b) a set of bearings that connect the axle to a rotating sleeve; and (c) at least three connection points fixedly connected to the rotating sleeve. The connection points are used to detachably attach an annular module to the hub using attachment elements that each comprise conical frustum surfaces. The attachment elements are configured to axially press a portion of the hub to a portion of the annular module, as well as radially aligning the hub to the annular module. The annular module also has a set of spoke attachment points configured for tensioned spokes that connect the annular module to a wheel rim. The spoke attachment points are in a circular configuration on two parallel offset planes that are perpendicular to the axis of rotation of the rim.

A system and method for ballistically cutting a multi-link metal chain comprises a chain alignment module that comprises three pins and attaches to the barrel of a firearm. A first pin and a second pin of the module fit on opposite sides of a target link of the chain. A third pin of the alignment module goes through a link adjacent to the target link of the chain. The three pins align the target link so that a bullet exiting the barrel of a firearm impacts a semicircular region of the target link to cause the target link to open.

A bicycle frame system comprises a connection module that rotatably connects a front frame section to a rear frame section. The connection module comprises a hinge section and a clamp section. The hinge section is below the clamp section when the bicycle frame system is in a ridable orientation. The connection module hinge section has a horizontal axis of rotation configured for rotating a front bicycle frame section approximately 180 degrees downwards and rearwards relative to a rear bicycle same frame section to convert the bicycle frame system from a ridable configuration to a folded configuration. The connection module clamp section comprises a front clamp block, a rear clamp block and a fastening device. The fastening device is configured to secure the front clamp block to the rear clamp block when the bicycle frame system is in a ridable configuration. The interface between the front clamp block and the rear clamp block comprises at least one v-shaped feature configured to prevent the front clamp block from moving laterally relative to the rear clamp block when the front clamp block is pressed against the rear clamp block.

System and method for packing a human-powerable wheeled vehicle

A system and method for packing a human-powerable vehicle uses two frame sections that pivot about a horizontal axis parallel to the central axis of the bottom bracket housing cylinder to convert from a rideable configuration to a packed configuration. The pivot axis for folding the two frame sections is located forward of a main seat tube and above a bottom bracket housing that are permanently and rigidly attached to each other and to rear stays for holding a rear wheel. The bottom of the main seat tube is located forward of the bottom bracket housing on the rear frame section. The front frame section rotates downward and clockwise, when looked at from the starboard side, through a rotation of approximately of about 180 degrees to convert from a rideable configuration to a packed configuration. A detachable connection located above the pivot axis rigidly secures the front frame section to the rear frame section when the frame is in a rideable configuration.

A system for packing a human-powerable vehicle uses an inner annular module that can be incorporated into a wheel. The inner annular module has a open central region, attachment points for steel spokes in tension that radiate out from the annular module, and a feature to facilitate the detachable attachment of a hub by a user, so that a user detachable hub can be installed in the open central region when the annular module is used as part of a vehicle wheel. Removal of the hub facilitates the placement of the module over the axle of a second wheel. The attachment points for the spokes that radiate outward are in a circular configuration that is concentric with the center of the annular module. The attachment points for the spokes are on two parallel planes.
