Abstract: A system and method for the microbiological purification of a liquid. The system includes a high-efficiency plate heat exchanger connected to a coil recirculation chamber via a high-efficiency infrared electric liquid-heater. The liquid enters the system at an ambient temperature, the temperature is raised by the heater and maintained in the chamber via recirculation by a pump. An electronic controller redirects the liquid through the exchanger to cool it and supply to a plumbed outlet. In combination, the system can be used to monitor and control various temperatures, pressures, flow rates, and heat exchanges in order to purify the liquid. The method includes steps to produce, install, implement, and use the liquid purification system to eliminate, neutralize, kill, or otherwise exclude/minimize biological organisms and contamination from the liquid.

Abstract: A rack for holding and organizing hair extensions comprises a vertical stand upon which a cylindrical member is attached at the upper end. A plurality of rack arms radiate outwardly from the cylindrical member. Each rack harm comprises a plurality of parallel and spaced apart teeth, the teeth having a groove between them. The width of the groove is sized such that the individual strands of hair of the extension fit through the groove, but the protein polymer at the end of the extension is too large to fit through the groove, such that the extensions may be suspended from the rack arms. The rack arms may be angled to facilitate placing extensions within the grooves, and removing the extensions from the grooves.

Abstract: An arrangement for mounting a sliding door to a vehicle body for movement between an open position and a closed position. The arrangement includes a guide track mounted to the sliding door, a carriage support arrangement carried by the sliding door and a swing arm. The swing arm is connected to the carriage for pivotal movement about a first axis and to the body for pivotal movement about a second axis. With the sliding door unlatched, the swing-arm rotates the carriage support arrangement and the sliding door through an obtuse swing angle, thereby reducing longitudinal tipping forces on the sliding door. Further, when the swing-arm and sliding door are in the full-open position, the sliding door's center of gravity is only slightly offset aft of the carriage support arrangement, thereby reducing the force needed to remove the swing-arm, carriage support arrangement and vehicle sliding door to a fully-closed position.
