Abstract: A personal formulation device for mixing and dispensing customized formulations from ingredient reservoirs carried by the device. The device may include a plurality of miniaturized progressive pumps with a flexible coupling between the motor and the pump. The coupling may include a spring (40). The device may include a spacer sleeve (62) having an internal diameter tapered to closely follow the motion envelope of the spring (40). Each pump may include a retainer (60) that is threaded into the interior of the pump body (52) to retain the spacer sleeve (62) and the drive end (120) of the rotor (34). Each pump may include a stator with an integrated flange seal (36). The flange seal (36) may extend around the circumference of the stator and be sandwiched between portions of the pump body (52). The stator may have a noncircular shape that keys the stator within the pump body. The pump may include an optical metering system.

Abstract: Device for the control and regulation of the feeding unit (60), as well as for monitoring of impressed current cathodic protection systems in reinforced concrete in order to avoid any risks of reinforcement (10) over-protection and to prevent hydrogen embrittlement problems, while assuring full protection of reinforcements.

Abstract: Method for the realization of soil reinforcement by means of cathodically polarized stainless steel units fearturing high corrosion resistance. The method applied foresees the use of stainless steel and carbon steel strips.
