Abstract: A water-insoluble polymer powder that can be redispersed in a liquid phase is obtained by proceeding as follows: first prepare a two-phase liquid-liquid system from a concentrated aqueous solution of a solute and a solution of the polymer in an organic solvent which is at least partially miscible with water, and then add water to it until all of the organic solvent has diffused into the aqueous phase. The polymer microparticles are then washed and dried. When resuspended in water, they result in a pseudo-latex.

Title: Semiconductor field oxide formation process
IPC: H01L21/762
Filed: 1988-05-31
Granted: 1993-09-15
Abstract: An integrated circuit fabrication process for creating field oxide regions utilizes a relatively thick pad oxide layer (2) below a masking nitride layer (22), and a second, very thin, sidewall masking nitride layer (9) formed on the sidewalls of a recess which extends through the layers (2, 22) and into the substrate (1). The thin sidewall masking nitride layer (9) does not utilize an underlying pad oxide layer. Upon oxidation, the thin sidewall nitride (9) is concurrently lifted and converted to oxide, the materials and dimension being selected to ensure that when the field oxide level approaches the level of the thick pad oxide layer (2) stresses at the corners of the active silicon region are relieved through various oxide paths and accentuated oxidation effects.

Abstract: A transmission antenna (4) radiates a microwave field, through a rectangular waveguide-shaped aperture applied against the separating surface (12) between a first medium (1), in which it lies, and a second medium (2), in which an object (3) is sunk or concealed. The microwave radiation reflected by the object (3) is collected by the aperture of a receiving antenna (5), also rectangular waveguide, shaped, juxtaposed with the radiating aperture of the transmission antenna (4). The radiation collected is measured at a plurality of points by virtue of a series of point-like antennas disposed in the collecting aperture. By virtue of the arrangement of the antennas, the collected radiation is usable as it stands, without having to subtract therefrom the result of a reference measurement. 
<??>The invention is applied, in particular, to obtain, nondestructively, pictures of the metal reinforcements concealed in reinforced concrete.

Abstract: Of the three potential ways of preventing limescale deposition     a) by ion exchangers,   b) a feeding unit or   c) an electronic descaling apparatus the last is the most expedient, since the change in the separation behaviour of calcium and carbonate is carried out prior to entry into the system in a purely physical manner; amorphous, that is, structureless, lime particles result which are in equilibrium with the carbon dioxide contained in the water. The quantities and the quality of the water remain unchanged. Influence is directly exerted on the flow through a measured section of tube (13) which is equipped at each of the two ends with a wound induction coil (13.1, 13.2), the magnetic lines of which are orientated identically. <IMAGE>

Abstract: Continuous manufacture of 1,1,1-chlorodifluoroethane from 1,1,1-trichloroethane and hydrofluoric acid by liquid phase reaction in the presence of at least one fluorination catalyst. According to the invention the operation is carried out at an absolute pressure of between 6 and 30 bars and at a temperature of between 50 and 120 DEG C, the catalyst content of the reaction mixture, expressed as weight percentage of metal, being between 0.05 and 10% and its content of organohalogen by-products outside 140 series being regulated at a value of less than 40% by weight. This process makes it possible simultaneously to obtain a high degree of conversion of hydrofluoric acid, to minimise the coproduction of 1,1,1-trifluoroethane and of organohalogen by-products, and to make it easier to recover the hydrochloric acid formed.

Abstract: A torsional tightener (101) is used, inter alia, for anchoring elements (108) in implants (103) anchored in bone. The tightener is releasable at a previously set torque and comprises an electric motor (406), a unit (403) changing the speed down, and a torsional tightening part. For the purpose of achieving a well-defined set torque value, the energy supply circuit of the electric motor can be interrupted at a certain current value in the energy supply circuit. The interruption and the rotational energy in the rotating parts of the torsional tightener after interruption are designed to cause a torsional tightening moment which is situated at or near an optimal or desired point on the particular moment curve for the tightening in question. Alternatively, a disconnection part is used, which interrupts the tightening function at or near the desired point on the moment curve. <IMAGE>

Abstract: On décrit un système de détection et de saisie de données sismiques générées par des sources de signaux sismiques classiques.  Le système comprend un capteur électrooptique et un processeur de signaux (10). Le capteur électronique émet de l'énergie lumineuse qui, après avoir été reflétée par la surface balayée de la mer (4), subit un décalage en fréquence par des mouvements d'eau de surface dus aux ondes de pression sismiques qui arrivent. Les différents signaux lumineux sont reçus séparément de chaque partie de la surface (12) par le capteur électrooptique, traités dans le processeur de signaux et enregistrés dans l'enregistreur de données (11). Grâce à ce sytème, la cartographie des formations sous-marines en mer peut être réalisée sans l'utilisation de câbles sismiques remorqués.
