In a first aspect, a process for forming deodorant or antiperspirant sticks by continuously forming a mobile composition for dispensing into containers or molds at a rate matched with the rate at which it is dispensed, and in other aspects a process in which a mobile deodorant or antiperspirant composition is dispensed by injection molding, i.e. a process in which the deodorant or antiperspirant composition is dispensed under pressure. The composition at the time of injection moulding is preferably either in the vicinity of its regular set temperature, particularly in the range of about 0-3° C. below the regular set temperature and/or partially structured at the time of its delivery it into a container or mold. The deodorant or antiperspirant composition is preferably continuously produced in a screw extruder, especially a twin screw extruder, which is controlled to deliver the composition in a substantially semi-solid state, at a temperature close to its regular set temperature and is injected into the container or barrel at a pressure at the point of injection that is often greater than 15 psi. and in many instances from 200 to 400 psi in the injection head. Apparatus for forming deodorant or antiperspirant sticks by injection molding is also described.

The objective of this invention, on demand hydrogen enhancement system for internal and external combustion engine, is to develop a continuous non pressurized water electrolyzer from clean water (not pure water or distil water) generator system. The mixed hydrogen gas and oxygen gas called “Oxyhydrogen”. Oxyhydrogen use as catalyse for internal and external combustion engine to increase fuel flame speed. It can use with variety fuels such as Ethanol, Methanol, Gasohol, Gasoline, Diesel, Bio Diesel, LPG, CNG, and LNG. This system can reduce fuel consumption, increase fuel efficiency, increase torque, reduce emissions, and reduce engine temperatures. The system required no cooling fan and electrolytic solution circulating pump. The system has less heat loss and very low electrical consumption. Oxyhydrogen will produce on demand as the engine RPM and load of generator. The control unit detects signal frequency from the alternator. Gas production rate low at low RPM and use less current and gas production will high at high RPM and use higher current. This can save lot of energy for the electrolysis process. In the past, water electrolysis use direct current (D.C.). In this invention the inventor uses D.C. with Frequency Modulate (FM) pulse width modulator (PWM) instead of Amplitude Modulator (AM) to control the electrolyzer (FMPWM). This circuit had current detector for automatic current adjustment and over current protection.
