Abstract: A circuit for reduction of energy consumption and improved per­formance of single- and three-phase asynchronous motors is pro­vided in the form of a merely electronic circuit varying in de­sign dependent on its purpose. With a single-phase asynchronous motor it is used to increase the secondary starting torque, to actuate a starting switch by auxiliary phase inductivity, to reduce energy consumption as compared with the typical con­ventional consumption, and to increase the starting torque during motor startup without the requirement of a centrifugal starting switch. With a three-phase asynchronous motor the cir­cuit of the invention achieves a reduction of energy con­sumption as compared with the typical conventional consumption. 
     The respective circuit includes an oscillating assembly con­sisting of a triac (T1), a diac (D1), a capacitor (C1) and a resistor (R1), to which other electronic elements may be added. The energy consumption reduction as compared with the typical conventional consumption of single- and three-phase asyn­chronous motors is effected by reduction of reactive motor currents thus to establish more natural operation conditions for the motor. As a byproduct, an increase of the starting torque during startup is obtained at lower energy consumption from the grid.

Abstract: Process for the noncontinuous polymerisation of vinylidene fluoride in an aqueous suspending medium with the use of an oil-soluble radical polymerisation initiator in the presence of a suspending agent in which the polymerisation takes place at supercritical temperature with delayed injection of a fraction of the vinylidene fluoride, the weight ratio of the fraction of vinylidene fluoride injected after a delay to that introduced initially into the polymerisation charge varying between 0.30 and 1.10. The process results in vinylidene fluoride polymers being obtained in the form of spherical particles whose apparent density is higher than 0.55 g/cm<3> and which can be varied at will up to approximately 0.90 g/cm<3> as a function of the ratio chosen. The vinylidene fluoride polymers obtained are suitable for powder-coating of articles, in particular for electrostatic spraying and rotational moulding.

Abstract: To improve forming properties of laminated structures comprising two sheets of a non-ferrous metal alloy connected by an adhesive, which hardens at heating and between which an adhesive layer is bonded to the metal sheets, a new sequence of heat treatments is proposed. The alloy of the sheets is in soft condition before the sheets are bonded to each other. The bonding temperature and time are selected such that it remains substantially in soft condition and only after forming further heating is applied to obtain hardening of the alloy sheets.

Abstract: An infrared detection device, e.g. for the 8 to 14 micrometre waveband, comprises a Langmuir-Blodgett or other very thin film (10) having pyroelectric or other temperature-dependent characteristics. At least one detector element having opposite electrical conductors (21 and 22) is formed in the film (10). The film (10) which may have a support layer (15) is mostly free of contact with a mount arrangement (25) which supports the film (10) in a very low thermally-conductive manner. In accordance with the present invention, the film (10) is very thin, but very efficient absorption of the radiation (31) is obtained in the following manner: the facing surface (26) of the mount arrangement (25) is reflective for the radiation (31); the sum of the optical thicknesses (n.t) of the film (10), (N.T) of any support layer (15) and (d) of a gap (28) forming the multiple layer detector-element structure along the radiation path to the reflector (26) is approximately one quarter of a selected wavelength (e.g. 9.6 micrometres) in the range to be detected; and the conductors (21 and 22) each comprise a resistive layer providing a sufficient resistance per square (Z1 and Z2, e.g. of twice the characteristic impedance of free space) as to absorb a substantial proportion of the incident radiation (31) and reflected radiation (32) in the wavelength range. Spaced supporting elements (252) below the film (10) can support the film (10) over the reflector (26) with a well-defined small gap (28) and carry an electrical connection to the second conductor(s) (22) below the film.

Abstract: A method for the destruction of halogenated organic compounds contained in a contaminated medium comprises adding an aqueous solution of polyethylene glycol to the contaminated medium in an amount to provide from about 0.1 to about 20 weight percent of polyethylene glycol, based on the weight of the contaminated medium. An alkali metal hydroxide is then added in an amount of from about 2 to about 20 weight percent, based on the weight of the contaminated medium. The medium is then heated to substantially dehydrate the medium and then further heated at a temperature between about 100 and 350°C to effect destruction of the halogenated organic compounds. An acid is then added to the medium in an amount sufficient to neutralize the same.

Abstract: A semiconductor radiation image detector consists of a semiconductor base (1) having its one surface plated with a common bias electrode (2) and its other surface plated with a plurality of two-dimensionally arrayed pixel-corresponding signal-takeout electrodes (3). The signal takeout electrodes (3) are provided with respective signal lead-out bumps (4). These bumps (4) are connected by a flip-chip joining technique with corresponding pads (6) provided on one side of a separately prepared base plate (5). The signal takeout electrodes (3) are thus free from many intertwining lead wires, making the detector free from problems caused by short-circuits forming across lead wires. 
     The detector receives a radiation image with the common bias electrode (2) directed to incident radiation rays, resulting in an increase in the image detection efficiency. 
     In manufacturing this radiation image detector, photoprocessing and metal-plating techniques are used.

L'analyse du rayonnement de sortie est effectuée par spectrosocopie, par exemple dans un interféromètre de Michelson balayable (13, 14, 15) associé à un détecteur (16). La détection par l'interféromètre permet d'identifier les dispositifs M1 à Mn qui sont soumis à des contraintes. Le même type de dispositif peut être utilisé pour détecter simultanément les contraintes et/ou les températures. L'invention s'appplique notamment à la surveillance de toute installation dans laquelle des contraintes sont à détecter. <IMAGE>
