  • Patent number: 11045812
    Abstract: An autogenous impact mill (10) is operative to size reduce friable material particles processed through operation of the mill. At least one impeller (58) rotatable within an interior area (44) of a housing (12) of the mill is operative to produce one or more air jets. The air jets are operative to suspend material particles using the Coanda Effect. Other particles moved by the air jets bounce off ricochet bars (74) and impact suspended particles so as to break and reduce the particles to a suitable size to pass through a screen (110) to an outlet opening (42).

  • Patent number: 10994124
    Abstract: An external defibrillator apparatus (10, 74) operates to deliver electrical shocks to the heart muscles of a patient using a self-contained piezoelectric power source. The apparatus has a body (12) which includes a handle portion (26) in fixed operative connection with disposed paddle portions (14, 16). Each paddle portion includes a respective electrode (22, 24). Manual movement of a trigger (28, 78) is operative to cause circuitry (32, 82) which includes a piezoelectric crystal (34) to develop sufficient electrical potential between the electrodes to deliver the electrical shocks to the heart muscles through external contact with the patient's chest.

  • Patent number: 10844765
    Abstract: An improved catalytic converter includes a Coanda chamber assembly connected upstream of a catalytic reaction chamber, where the exhaust pipe is to be connected to the Coanda chamber assembly. The Coanda chamber assembly forms a Coanda chamber that has at least one narrower section and at least one wider section immediately downstream of the narrower section, with openings formed at the narrowest point of a narrower section. In operation, when engine exhaust gas is fed into the Coanda chamber, the gas pressure increases at the narrower section, and drops when the gas enters the wider section. As a result, air is sucked into the Coanda chamber via the openings and mixes with the exhaust gas. This lowers the exhaust temperature and enhances the efficiency of the catalytic reactions in the catalytic reaction chamber.

  • Patent number: 7931814
    Abstract: An alloy is created by melting aluminum, zinc, rare earth metals such as erbium and/or tellurium, and optionally vanadium. During cooling, the molten alloy is exposed to ultrasonic waves in order to prevent separation of the alloy into layers. The alloy is used for one electrode and a separate conductive element such as stainless steel or carbon is used for the other electrode in a water filter. A constant potential difference and electrical current is created between the two electrodes across the water. In an embodiment where carbon or zeolite is used as the filtration medium, the constant voltage and current increase bonding of ions in the filtration medium with pollutants in the water. In an embodiment wherein a mixed bed resin containing sodium ions and potassium ions is used as the filtration medium, the constant voltage and current increase the bonding of the sodium and potassium ions with residual chlorine ions in the water.
