Patent EP-0091724-A1 (EP)
Inventor: HICKS JOHN MERRILL
IPC: H05B41/282
Filed: 1983-02-11
Abstract: Starting and operating method and apparatus for discharge lamps comprises a current-limiting and rectifying means which provides at its output a low-ripple current-limited direct current. To effect lamp starting, a series-connected inductor and capacitor form a high "Q" resonant circuit with the capacitor connected and across the lamp to be operated. This starting circuit connects through a blocking capacitor and charging resistor across the low-ripple source of DC. A pair of transistors which comprise an oscillator are connected emitter-to-collector across the source of DC, with the common-connected emitter and collector connected to the blocking capacitor. A drive air-core transformer has separate feedback windings in the starting and operating circuits and drive windings are associated with the transistors. A trigger diode is used to initially pulse one of the transistors which initially oscillate to generate square waves having a frequency corresponding to the resonant frequency of the starting circuit. After the lamp strikes, the transistors operate in a self-oscillating mode with the operating frequency determined by the rate of current flow into the operating feedback winding.

Abstract: 1. A process for determining the dissolved and precipitated concentrations of an element, such as aluminum, in a metallic analysis sample (4) by Optical Emission Spectrometry, in particular a steel sample, comprising the steps of determining said concentrations on the basis of the spark erosion profile in time (18) of said element and reading on calibrating charts set for known samples, characterized by the steps of - submitting the sample (4) to mild spark erosion conditions for the entire duration of the analysis in such a way as to avoid any phenomenon of local refusion of the sample ; - dividing the spark erosion profile (18) thus obtained for the element under analysis into at least two successive parts : an initial part formed by a peak (19) and a terminal part formed by a horizontal flat portion (20) ; - considering a standardized value I3 of the intensity of the complete spark erosion profile and determining on the basis of I3 the total concentration [M]t of the element under analysis by reading on the corresponding calibrating chart constructed on the basis of said standardized value, - considering a standardized value I2 of the intensity of the horizontal flat portion (20) and determining on the basis of I2 the concentration in the dissolved state [M]d of the element under analysis by reading on the corresponding calibrating chart constructed on the basis of said standardized value ; - and calculating on the basis of the values I3 and I2 and of the total concentration [M]t the concentration in the precipitated state [M]p of the element under analysis with the aid of the relation : [M]p =[M]t J-I2 /I3 -I0 wherein I0 is the value at the origin of the intensity on the calibrating chart giving the total concentration [M]t and J is the standardized value of an intensity of the spark erosion profile representative of the sum of concentrations in the dissolved and precipitated states of the element under analysis.

Abstract: Au cours de la fabrication de toute sorte d'articles, des substances contaminantes organiques se fixent aux surfaces de ces articles et doivent en être ultérieurement retirées. Le procédé décrit est efficace pour retirer des substances contaminantes organiques de toute sorte d'articles et pour permettre de retirer rapidement de telles substances contaminantes sans endommager l'article. Ce procédé est spécialement utile pour nettoyer les composants utilisés dans le domaine aérospatial. Dans le procédé décrit, un composant structural portant la substance contaminante est mis en contact dans un récipient à pression avec un gaz dans des conditions de température et de pression surcritiques, ce qui entraîne l'absorption de la substance contaminante par le gaz. Le gaz, ayant absorbé la substance contaminante, est ensuite évacué du récipient afin d'obtenir un composant nettoyé.

Abstract: 1. A transmission system for high bit rate digital signals comprising intermediate regenerators and line terminal devices, each of which includes phase regulating loops with a clock generator (G), wherein, in order to form a transmission channel for additional signals (ZSE), at the transmitting end a phase modulation of the clock pulses for the outgoing digital signals takes place, in which the control input of a clock generator included in the transmitting-end line terminal device is supplied with the additional signals via an adder stage (AS), where the first input of the adder stage is connected to the output of a phase discriminator (PD1) included in the transmitting-end phase regulating loop, and the other input of the adder stage is connected to the input for the additional signals, where at the receiving end the additional signals are filtered out of the regulating voltage of the phase regulating loop of the receiving-end line terminal device, and where the intermediate regenerators are conductive in respect of the phase fluctuations, produced by the additional signals, of the digital signal pulses, characterised in that for the block-by-block recoding of the digital signals, the line terminal devices each comprise a transmitting-end and a receiving-end code converter and these code converters respectively include, between a receiving-end series-parallel converter (SP) and a transmitting-end parallel-series converter (PS), a recoding logic unit (UL) and an intermediate store (ZS) in a freely selectable sequence, that the additional signals are input-coupled into the transmitting-end code converter (CUS) via a pre-emphasis stage (PES), where the modulation frequency (fMOD ) at which occur the additional signals which are to be transmitted, corresponds at least approximately to the geometric mean between the cut-off frequency fg (CUS) of the narrow-band phase regulating loop in the transmitting-end code converter (CUS) and the cut-off frequency fg (REG) of the phase regulating loop of the following intermediate regenerators, that for the restoration of the additional signals the phase discriminator is included in a receiving-end code converter (CUE) and that the quality of the phase regulating loop in the two code converters (CUE, CUS) is substantially greater than in a transmission system which has no transmission channel for additional signals.

A non-rating watertank (35) mounted within the cylinder (12) collects the water discharged from the troughs (30) when each reaches a certain height. In a further embodiment the layer (18) includes funnel-shaped apertures (50) which communicate directly with respective apertures (17) in the cylinder (12), and the outer surface of the layer (18) is covered with a non-porous rubber sheet (60) except at the entrance (62) to the apertures (50) in the layer (18). In this case the resilient layer (18) may not be of open cell structure.

Abstract: This invention relates to an emulsion flowable formulation of 2-chloro-2', 6'-diethyl-N-(methoxymethyl)acetanilide (commonly known as alachlor) and 2-chloro-4-athylamino-6-isopropylamino-1,3,5-triazine (commonly known as atrazine). An emulsion flowable formulation consists of three phases: an organic phase (discontinuous phase) dispersed in an aqueous phase (the continuous phase), i.e., the oil-in-water emulsion, and a solid phase dispersed throughout the continuous phase. In the formulation of this invention, alachlor dissolved in organic solvent forms the organic or discontinuous phase which is dispersed throughout the aqueous or continuous phase; the solid phase, atrazine, is also dispersed throughout the continuous phase.
