Filed: 1991-11-05
Abstract: The subject of the invention, a hydroactive separator of solid particles and liquids from air currents, eliminates filtering of the air current by means of a paper or textile filter sack or any other kind of filters. Removing solid particles (dust) and liquids (water) from the air current is achieved by a liquid presenting the medium which traps the particles or liquid droplets from the air current. In vacuum cleaners, a constant suction power during the whole time of operation is achieved. Abrasive materials, hot and incandescent fragments (ashes, glow, cigarettes, weld butts), as well as other materials may be removed without preliminary preparation of the vacuum cleaner. An important saving of paper or textile filter sacks is effectuated.

Abstract: Disclosed is a fiber amplifier system including a gain fiber (10) having a single-mode core containing dopant ions capable of producing stimulated emission of light at wavelength λ s  when pumped with light of wavelength λ p . Absorbing ion filtering means (17) is operatively associated with the gain fiber (10) to alter the gain curve. If the absorbing ions are the same as the gain ions of the gain fiber, the system further includes means for preventing pump light from exciting the gain ions of the filtering means (17). The excitation prevention means may take the form of means for attenuating pump light. If the absorbing ions are different from the dopant ions of the gain fiber, such absorbing ions can be subjected to light at wavelength λ p , but they will remain unexcited. Such absorbing ions can be used to co-dope the gain fiber, or they can be incorporated into the core of a fiber that is in series with the gain fiber.

Inventor: CLARKE JOHN ROBIN PAUL
IPC: G01F1/84
Filed: 1991-05-29
Abstract: Fluid flow is measured by exciting a vibratory system 11 with a sinusoidal driving force with a frequency corresponding to the natural frequency of the system and exposing the system to vibration induced by the fluid flow, eg. by passing the fluid through ducting 11 forming part of the vibratory system. A spectral representation of the vibration of the system is obtained by means of a detector 18 located at a pseudo-node of the system, eg. a nodal plate 14a, and the signal is analysed to derive the fundamental frequency component and a harmonic component, typically the first even harmonic, which is favoured by the design of the system. The ratio of the harmonic and fundamental components is computed and provides a measure of the fluid flow to which the system is exposed. The technique may be used as a check facility for a Coriolis mass flow meter.

Abstract: A method of protecting casing during high pressure well stimulation. An annulus between the casing and tubing is loaded with water via a small volume of nitrogen to partially displace annular fluid down the annulus and up the tubing. This loading takes place prior to setting a packer. Loading in this manner results in a gas "cushion". If the tubing should burst during high pressure stimulation, compression of the "cushion" will prevent the casing from rupturing.

Abstract: The invention relates to a low voltage-high voltage convertor of the flyback type. This convertor comprises a transformer (T) whose primary is connected to the supply voltage UA via a switch (Q) and whose secondary is connected to the terminals of a capacitor (C) via a rectifying diode (CR). Conventionally, this convertor comprises a secondary regulating loop comparing the output voltage, via a divider bridge (R1, R2), with a setpoint voltage in order to regulate the off time (Toff) of the switch. There is provision for keeping constant both the primary energy stored in the transformer, regardless of the voltage UA, and the total charging time for the capacitor. To do this, use is made of digital control means (11, 8', 90 to 92) in order to govern, in open loop, the on time (Ton) of the switch (Q) with the value of the supply voltage and with the temperature provided by a sensor (10). The invention applies in particular to high-energy ignition systems. <IMAGE>
