Title: Colloid decomposition method and apparatus for electrochemically resolving emulsions
Inventor: SCHREMMER ISTVAN
IPC: C02F9/10
Filed: 2010-04-08
Abstract: Decomposition is performed with the application of the method and apparatus by separating solid contaminants from the emulsion, absorbing CO2 gas in the emulsion, thereby switching the emulsion type from W/O to O/W, pre-heating the emulsion utilizing a heat regenerator (32), setting the stability minimum of the emulsion by adjusting the pH, resolving the emulsion in an electrochemical decomposition reactor (38) by passing it between an anode made of electrochemically active material and a cathode made of electrochemically inactive material, while the colloid particles of the emulsion are bound in flocks forming a foam utilizing as a flocculant the compound produced in situ from the electrochemically active anode, - discharging the foam produced in the above step, and - discharging the decontaminated water through a final settlement tank (47) and/or a final filter (44) and a heat regenerator (32).

Abstract: A Roots-type blower comprises a housing defining a rotor chamber and an inlet and outlet to the rotor chamber. First and second rotors are mounted in the rotor chamber, each rotor defining a plurality of lobes, adjacent lobes and the housing cooperating to define gas transport chambers. The blower is configured so that a net flow rate of gas into a gas transport chamber is generally or approximately constant, whereby a change in gas pressure in the gas transport chamber is generally or approximately linear, as the gas transport chamber approaches the outlet. In one embodiment, this is accomplished by providing flow channels extending from the outlet towards the inlet, and from the inlet towards the outlet, corresponding to each rotor. The flow channels permit gas to flow from the high pressure outlet to a gas transport chamber and from the gas transport chamber to the low pressure inlet.

Abstract: A method of controlling electrosurgical power delivery based on a comparison of sensed tissue impedance to various impedance threshold values is provided. Energy is delivered to tissue in a sealing cycle as a series of pulses. An initial pulse has a profile with a preset energy starting value that increases at a ramping rate to a preset end value. Sensed impedance data are monitored throughout each pulse and compared to each of an impedance threshold value for RF setpoint, an impedance threshold value for cumulative time, and an impedance threshold value for energy cutback. Based on sensed impedance during a pulse, the profile of a subsequent pulse can be modified. In the event of a high impedance event that reflects low tissue presence, energy may be cutback. A sealing cycle is stopped when a cumulative amount of time with an impedance value over the impedance cumulative time threshold value reaches a sealing cycle duration limit.
