Patent CA-2434075-A1 (CA)
Inventor: KRASILCHIKOV YEHEZKEL
IPC: G01F3/22
Filed: 2001-11-05
Abstract: A fluidic gas metering system interposed in a line running from a gas source to a user site to meter the gas stream being supplied to the user in a broad flowrate range defined by a low flowrate band at the lower end of the range, a medium band at the middle of the range and a high band at the upper end thereof. The system includes an input chamber which receives a stream of pressurized gas from the source and an output chamber from which the gas is supplied to the user. Intercoupling the chambers are three gas flow channels.  The first channel is defined by a first fluidic generator operative only when the flowrate of the gas lies in the low band to yield periodic pulses whose frequency is proportional thereto. The second channel is defined by a second fluidic generator operative only when the flowrate of the gas lies in the medium band to yield periodic pulses whose frequency is proportional thereto.  The third channel is defined by a bypass passage operative only when the stream lies in the high band, the bypass acting to divide the gas stream between the second and third channel whereby the second generator then meters flowrate in the medium band. The periodic pulses yielded by the first and second generators are processed and totalized to provide accurate readings of the gas consumed by the user throughout the full range.

Filed: 2002-06-28
Abstract: A method and a device involving an electric iris diaphragm/shutter are disclosed for controlling particle transfer of electrically charged medicati on powder particles from a source to a defined area, the target area, of a substrate. Spatial distribution of particles onto the target area or dose be d is achieved by means of electro-dynamic field technique (320) applied to the distribution and deposition of particles in a dose forming process. An electric iris diaphragm/shutter (130) is located between a particle generato r (110) and the substrate (140) such that all particles must pass the iris diaphragm for being transferred to the substrate. By adjusting amplitude and frequency of a superimposed AC potential (136) charged particles will oscillate in the created AC field such that only small light particles will emerge from the iris diaphragm/shutter for further transfer in the dose forming process. Furthermore by the adjustment of amplitude and frequency a majority of charged particles emerging are accelerated and retarded in synchronism with the AC field, such that they impact on a defined target are a of the substrate with a low speed and momentum resulting in a desired dose porosity.

Title: Aluminium production cells with iron-based metal alloy anodes
Inventor: NGUYEN THINH T
IPC: C25C3/12
Filed: 2002-08-02
Abstract: An iron-based metal anode for the electrowinning of aluminium by the electrolysis of alumina in a molten fluoride electrolyte has an electrochemically active integral outside oxide layer on an iron-based alloy that consists of 75 to 90 weight % iron; 0.5 to 5 weight % in total of at least one rare earth metal, in particular yttrium; 1 to 10 weight % aluminium;  0 to 10 weight % copper; 0 to 10 weight % nickel; and 0.5 to 5 weight % of other elements. The total amount of aluminium, copper and nickel is in the range from 5 to 20 weight %; and the total amount of rare earth metal(s), aluminium and copper is also in the range from 5 to 20 weight %. The electrochemically active surface layer is predominantly of iron oxide that slowly dissolves into the electrolyte during operation and is maintained by progressive slow oxidation of iron at the interface of the bulk metal of the alloy with the oxide layer. This progressive slow oxidation of iron corresponds to the dissolution of iron into the electrolyte which remains at or below saturation level at the operating temperature, the operating temperature being maintained sufficiently low to limit the contamination of the product aluminium to an acceptable level, and the electrolyte being circulated to maintain a sufficient concentration of alumina in the anode cathode gap.
