Title: Produits corroyes en alliages d'aluminium a caracteristiques mecaniques ameliorees et procede pour les obtenir
Inventor: BOUVAIST JEAN M A

Granted: 1979-04-17
Abstract: L'invention concerne des produits corroyés en alliages à base d'aluminium, à très faible teneur en hydrogène.  Ces produits sont dotés d'une structure isotrope à grains équiaxes, donnant des caractéristiques mécaniques sensiblement égales dans toutes les directions, et possèdent une vitesse critique de trempe particulièrement basse.  Ils sont obtenus par traitement thermique à une température un peu supérieure à la température de solidus.  Ils permettent un allègement sensible de certaines pièces, en particulier en construction aéronautique, et la mise en oeuvre d'une trempe à l'eau bouillante ou même à l'air sans diminution sensible de caractéristiques mécaniques.

Abstract: ABSTRACT OF THE DISCLOSURE        It is known to enzymatically hydrolyze gelatine into low molecular proteins which are easily wettable and resorbable.  Such products have a low content of essential amino acids.  It has been proposed to add to the hydrolyzed gelatine, hydrolyzed whey.  Hydrolyzed whey has a bitter taste.  The present invention seeks to overcome this drawback by providing a process for the preparation of easily wettable, water-soluble protein products by enzymatic treat-ment of natural proteins, characterized in that the protein substances are hydrolyzed in an aqueous suspension by proteolytic enzymes of low activity at a temperature between 40 and 60°C and at an optimum pH value for the activity of the proteolytic enzyme so that the end protein product has a flocculation temperature of over 80°C and no bitter taste.

Abstract: ABSTRACT OF THE DISCLOSURE           The finished surface of a metal sheet is protected with a removable film of thermoplastic material bonded to the finished surface along a grid-like pattern of lines that form hermetic seals for a plurality of discrete gas pockets between the finished metal surface and the film.  The product is formed by preheating the metal to bonding temperature, by then bringing a discrete film of thermoplastic material into contact with the finished surface, and by pressing the film against the heated metal sur-face with a resilient pattern of ridges to form the aforesaid pattern of seal lines.

Abstract: Abstract of the Disclosure An automatic titration system and method in which the titrant is generated electrolytically and a two-position slider type ceramic sample valve, reliably, accurately and repetitively obtains a volumetric sample from a process loop and introduces it to a titration cell containing a generator or working compartment and an auxiliary compartment separated by a porous frit.  The system also includes a two-position slider type ceramic reagent valve for introducing reagent into the titration cell.  Titrant created at a generator electrode surface is dispersed into the bulk of the solution by a magnetically coupled impeller in the working compartment which mixs and also pumps the contents of the cell through the reagent and sample valves in a closed loop.  Generator and auxiliary electrodes are connected to a current source which provides the electrolysis current.  The progress of the titra-tion is monitored by indicating and reference electrodes in the titration cell connected to an appropriate endpoint indicator, output of which is com-pared to a known set point corresponding to the titration endpoint.  The total charge delivered to the generator and auxiliary electrodes during titration is measured by a time or integrator and read out as a trend output signal. The automatic titration system and method of this invention advantageously lends itself to microprocessor control over the titration reaction and titra-tor sequencing, and thus finds application in on-stream process monitoring and control systems.

Abstract: ABSTRACT       The apparatus for isolation of Trichinella larvae has a vessel formed by the upper cylindrical part and the lower conical part. The upper and the lower parts of the vessel are separated by a gauze having the openings through which the larvae can pass. The apparatus has a conical lid inside which an electric motor, operating the stirrer installed in the cylindrical part of the vessel, is mounted. A settling vessel intended to collect Trichinella larvae is attached to the lower conical part of the vessel.  According to the invention several such apparatuses can be installed on a common frame and placed inside a com-mon thermostatio chamber. This makes it possible to examine samples taken from several groups of animals. It is recommen-ded to load the apparatus with a sample comprising specimens of a group of carcasses, and if  trichinae are detected in the settling vessel, each carcass should be examined sepa-rately.

Abstract: ABSTRACT           Medical specimens suspected of containing harmful microorganisms are diluted in saline solution and the dilution so formed is vacuum loaded into a cuvette or card containing viewing wells having dried selective culture media therein.  The dilution rehydrates the culture media, each of which is selective in the sense that its optical characteristics will change when the organism to which it is specific metabolizes within it. A plurality of the cards are loaded into a tray, and the tray is placed on a rotatable carousel of a card holder unit along with other trays.  The carrousel is indexed at periodic intervals, and each time that it is indexed a different tray moves to a reading position facing a card reader unit.  The carrousel has a center stack from which heated air is discharged such that it passes along both major surface areas of the cards in the tray, thus maintaining the cards at a temperature suitable for incubating microorganisms in them.  The reader unit includes a reader head which moves vertically along that tray which is in the reading position, and this head has extractor and locator slides which move horizon-tally.  The extractor slide engages each card and withdraws it individually from the tray, while the locator slide, which is spring loaded with respect to the extractor slide, bears against the card as it is withdrawn so as to maintain it in the proper orientation with respect to arrays of light emitters and corresponding detectors on the reader head.  The emitters and detectors are arranged in pairs, with the detector or each pair being illuminated by the emitter, unless otherwise obscured.  The card as it is withdrawn by the extractor slide moves between the pairs of emitters and detectors, and as it does some of the pairs register with identification segments on the card while other pairs register with the viewing wells.  The former "read" identification numbers marked on the card with opaque ink, while the latter determine the light transmitting characteristics of the wells, this being achieved by projecting the light from the emitters through the wells and measuring the intensity of the light falling upon the detectors.  A change in the light transmitting characteristics of a well indicates the presence of the specific microorganism in the well.  That change provides a unique signature for the specific microorganism
