Title: Method and apparatus for reducing operating and maintenance costs and emissions in a chemical and/or fluid injection system
Inventor: LEE ROBERT E
IPC: F17D3/01
Filed: 2002-06-17
Abstract: A method and apparatus for reducing operating and maintenance costs and emissions in a chemical and/or Fluid Injection System. A first step involves providing an electronic flow controller system. The electronic flow controller system consists of three main components: 1. Electronic monitoring and control system making up control box 2. Metering chamber and 4 solenoid actuated valves making up valve assembly 3. Power supply The invention sends a series of pulses from the control box to the valve assembly by means of an electrical cable. The signals cause the valves to open and close first filling the metering chamber with fluid and then discharging fluid into desired injection points this then constitutes one cycle. The number of cycles per day would determine the amount of fluid that would be discharged into the injection point. The fluid for the system would be provided by a tank or vessel mounted on a stand to provide a gravity feed to valve assembly. Power for the system could be supplied by A.C. where available or D.C. by means of batteries and solar power. Operation of the chemical and/or Fluid Injection System is in response to external inputs such as temperature or flow monitors.

Patent CA-2407106-A1 (CA)
Inventor: NICOLA THOMAS
IPC: B32B25/00
Filed: 2001-03-16
Abstract: The invention relates to an elastic, substantially non-stretched film produced from olefinic materials that is completely free of PVC and that is yet adapted to the requirements of a film, such as a film for medical purposes, for example for heat sterilization. The inventive film has elastic properties up to a certain point that depend on the film's thickness, that means no permanent deformation can be observed. When the tensile stress is further increased, the film is deformed, that is it shows a plastic behavior until it finally tears or breaks. The transition is fluid since, unlike conventional films, the inventive film has no negative increase in the yield point. The increase in the yield point is >= 0. The invention further relates to the use of the inventive films, for example in the field of medical engineering, and to bags for medical purposes that comprise at least one film according to the invention.

Title: Method and electronic apparatus for reversing the rotation of an engine
Inventor: VENTUROLI ALESSANDRO
IPC: F02P11/02
Filed: 2002-12-12
Abstract: A method and an electronic apparatus for reversing the rotation of a two-stroke internal combustion engine, provided with an ignition system powered by a permanent magnet voltage generator. The electronic apparatus comprises a microprocessor control unit programmed for controlling the sparking both during forward and backward rotations, and for controlling the reversal rotation procedure of the engine. The reversal procedure is controlled on the basis of information obtained from a first binary signal emitted by a bistable magnetic sensor activated by the magnetic flux of the generator, and from a second binary signal correlated to the polarities of output voltage of the voltage generator. The original forward or backward rotation is made to reverse by providing a sparking delay, and subsequently generating an advanced spark while the engine is still rotating in the original direction.

Abstract: A low-noise directional microphone system includes a front microphone, a rear microphone, a low-noise phase-shifting circuit and a summation circuit. The front microphone generates a front microphone signal, and the rear microphone generates a rear microphone signal. The low-noise phase-shifting circuit implements a frequency-dependent phase difference between the front microphone signal and the rear microphone signal to create a controlled loss in directional gain and to maintain a maximum level of noise amplification over a pre-determined frequency band. The summation circuit combines the front and rear microphone signals to generate a directional microphone signal.
