Abstract: An apparatus for purifying air comprising two electrodes having a dielectric material such as glass extending therebetween. The dielectric material is air permeable, for example in the form of a bed of discrete particles such as glass beads. The electrodes are also air permeable, allowing the air to flow through the electrodes and dieletric.  Ozone is generated by discharge at points of contact of the dielectric particles. Airflow through the device is improved, allowing greater cooling, and higher volumes of airflow but at lower concentrations of ozone production than with prior art devices, thus reducing toxicity.

Abstract: A method for preparing a highly crystallized metal powder, comprising: supplying at least one heat-decomposable metal compound powder into a reaction vessel using a carrier gas; and forming a metal powder by heating the metal compound powder in a state in which the metal compound powder is dispersed in a gas phase at a concentration of no more than 10 g/liter, at a temperature that is over the decomposition temperature of the metal compound powder and at least (Tm - 200)°C when the melting point of the metal contained in the metal compound powder is Tm°C. The method provides a high-purity, high-density, highly dispersible, fine, highly crystallized metal powder consisting of spherical particles of uniform size, which is suited to use in thick film pastes, and particularly conductor pastes and the like used in the preparation of multilayer ceramic electronic parts.
Patent CA-2347162-A1 (CA)
Title: System and method for frequency up-conversion
Inventor: BULTMAN MICHAEL J
IPC: H04L27/20
Filed: 1999-10-18
Abstract: A method and system is described wherein a signal with a lower frequency is up-converted to a higher frequency. In one embodiment, the higher frequency signal is used as a stable frequency and phase reference. In another embodiment, the invention is used as a transmitter. The upconversion is accomplished by controlling a switch with an oscillating signal, the frequency of the oscillating signal being selected as a sub-harmonic of the desired output frequency.  When the invention is being used as a frequency or phase reference, the oscillating signal is not modulated, and controls a switch that is connected to a bias signal. When the invention is being used in the frequency modulation (FM) or phase modulation (PM) implementations, the oscillating signal is modulated by an information signal before it causes the switch to gate the bias signal. In the amplitude modulation implementation (AM), the oscillating signal is not modulated, but rather causes the switch to gate a reference signal that is substantially equal to or proportional to the information signal. In the FM and PM implementations, the signal that is output from the switch is modulated substantially the same as the modulated oscillating signal. In the AM implementation, the signal that is output from the switch has an amplitude that is a function of the information signal. In both embodiments, the output of the switch is filtered, and the desired harmonic is output.
