    摘要: A recorded technique for teaching a target language to a student having a home language in which each expression in the home language is presented and, under control of the student, time is provided for the student's oral translation thereof. Subsequent to the student's oral translation, a first example student translation of the expressions to the target language is provided and subsequently a second example student's translation of the target language is provided. One ID of the example students is preferably male and the other is preferably female. Then a teacher's translation of the expression into the target language is provided. The sequence is repeated for a series of expressions. To facilitate student comfort and reduce anxiety, the student can provide pauses wherever convenient and in particular the system gives the student time to translate the expression provided from the student's home language into the target language.

    摘要: Process for recovering a solvent from a gas coming from a treating process using the solvent, the gas having a low temperature Ta and a high temperature Td, the difference Td-Ta being sufficient to carry out an adsorption step and a desorption step. The process is characterized in that/ a) a first solvent-containing gas stream is sent to an adsorption step, this gas being at a temperature Ta, at the end of this step the gas is practically solvent-free and the solvent is collected in a first adsorber, b) a second gas stream at a temperature Td, this gas being solvent-free, is sent to carry out desorption of a second adsorption means loaded with solvent during a previous step a), and c) the solvent is sent at least partly to a step of the treating process using the solvent.

    摘要: A medical apparatus for the extracorporeal treatment of blood or plasma comprises a semi-permeable membrane consisting of at least one electronegative polymer, such that the surface of the semi-permeable membrane has negative electric charges. Before the sterilization of the apparatus, and before or after the formation of the membrane, at least one cationic and anti-protease agent is incorporated in at least one part of the membrane, this agent undergoing bulk adsorption or semi-bulk adsorption in the membrane and/or being bound by an ionic interaction with the electronegative sites of the membrane.

    摘要: An acidic aqueous cleaner, preferably in emulsion or microemulsion form, which is of a pH in the range of one to four and is useful for cleaning hard surfaced items, such as bathtubs, sinks, tiles and porcelains and even some such items which are not acid resistant, such as those of a European enamel known as zirconium white enamel, comprises synthetic organic detergent, such as a mixture of anionic and nonionic detergents, e.g., sodium paraffin sulfonate, higher fatty alcohol ethoxylate sulfate and higher fatty alcohol or phenol ethoxylate, organic acids, e.g., mixture of succinic, glutaric and adipic acids, phosphonic acid, e.g., aminotris-(methylenephosphonic acid) and phosphoric acid in an aqueous medium. The acidic cleaner is useful to remove soap scum, lime scale and grease from surfaces of the mentioned items without adversely affecting such surfaces, and removals of the scum, scale and grease are easy, being effected by applying the microemulsion to the surface to be cleaned, followed by wiping it off. Although the cleaned surfaces may be rinsed, that is often not necessary and the surfaces will be left clean and shiny after wiping, even without rinsing, or with minimal rinsing. In the described emulsions, the organic acid components effectively remove soap scum and lime scale, the detergents remove greasy soils and promote effective contact between the acid and the surfaces to be treated, and the combination of phosphoric and phosphonic acids prevent acidic attack by the organic acid(s) on the European enamel surface being cleaned.

    摘要: A process for the thermal conversion of various fossil organic materials such as heavy crude oils, heavy petroleum fractions or refining residues, is described. According to the invention, the charge is subjected to thermal processing in the presence of a minor proportion of at least one radical-generating monooxygenated compound, containing at least one heteroelement selected from sulfur, and nitrogen and in which the oxygen is borne by said heteroelement. The conversion is improved with a composition comprising a hydrogen donor diluent and this monooxygenated compound in a weight ratio of 0.2:1 to 400:1. The invention is useful in the petroleum industry and the coal industry and particularly in the process of hydrovisbreaking.

    摘要: The invention concerns the reading by optical means of data recorded along a track on a disc; an address code, which increases one unit at each step, is recorded on the disc at the same time as the data. The optical reader contains a device for the fast movement of the reading head in a direction radial to the disc, a device for counting the number of track grooves thus crossed, a device for automatic access to some given data which contains a device for detecting addresses recorded and a programmed control circuit which triggers fast movement or a step by step movement of the reading head depending on whether the reading head is far from the track groove whose address has been recorded or is near to this track groove.
