摘要:
The invention concerns in particular a protective coating chemically fixed on a metal substrate, comprising an amorphous mineral silicate at least 1 νm thick and having the following adhesive properties: passes the adhesive test after being folded at 180°, passes the adhesive test of the 160 shock with the equipment as per the ISO/TR 6272-1979 standard, passes the adhesive test after thermal shock. The invention is applicable to coated substrates, in particular, as goods or parts of goods subjected to aggressive environment and/or mechanical and/or thermal stresses.
摘要:
Viral recombinant pseudo-particles characterized in that they are formed by self-assembly of at least one protein having a viral structure, in that they have a size comprised between about 20 and 60 nm, in that they form an approximately icosahedral structure, an in that said protein is modified by the presence of at least one epitope comprising a sequence from 8 to 25 amino acids which is susceptible of association to at least one molecule of class I and/or II of the major histocompatibility complex, with the exclusion of the epitope C3:T, said association being recognized by cytotoxic lymphocytes TCD8+ and/or TCD4+. Said pseudo-particles may be used as anti-viral vaccines or as medicaments.
摘要:
A sorting machine with a standard operator work space containing a compact and ergonomic assembly of a hopper (5) for a horizontal stack of envelopes (3) between a control panel (6) and an extraction head (9), and a set of pigeonholes (11) for receiving a large enough number of sorted envelopes to prepare, e.g., a postman's round, said pigeonholes being arranged behind a transparent panel above the hopper, and supplied by a conveyor moving along a path in such a way that the orientation of the envelopes remains the same as they are delivered from the hopper (5) to the pigeonholes (11) before being simply tipped therefrom into the hopper. Said machine is similar to an office machine and is compact mainly because letters are conveyed widthwise and a suitable monitoring and control system is used.
摘要:
A winch consisting of a drum (2) in the form of a cylinder (3) axially rotated under the control of a power unit (7) combined with a reduction unit (8), said drum (2) having a rotational locking assembly (20), e.g. a band or disk brake, separate from the power unit (7). At least one part of the motor-reduction unit (7, 8) is housed in the cylinder (3) of the drum (2) and the motion output by the reduction unit (8) goes in two directions, i.e. towards the drum (2) and, externally to the drum, towards an adjacent or complementary rotary device (25, 26, 30, 33, 35, 42, 43, 46). The output (10) of the power unit and the input (10) and output(s) (12, 13) of the reduction unit (8) are centred on the axis of said drum (2).
摘要:
A method and equipment for determining the stability of an emulsion placed in an analyser cell and produced by mixing two non-miscible primary phases (6, 7), namely a conductive continuous phase and a non-conductive dispersed phase. The method comprises a step of measuring changes in conductivity within said emulsion in a portion of the cell which corresponds to the space occupied by one of said primary phases (6, 7) (either the conductive phase or the non-conductive phase) when they are at rest. The equipment for carrying out the method consists of an analyser cell (1) provided with conductivity measurement electrodes (3) connected to a conductivity meter. The electrodes (3) extend vertically through a portion of the cell column (1) and measure the conductivity of the sample being analysed therein, which portion corresponds to the space occupied by one of said primary phases (6, 7).
摘要:
Process and device for the treatment of polluting molten meltable and electrically conducting materials consisting in feeding the waste materials into an induction furnace (11, 40) comprising an inductive circuit (1, 39), directly induction heating said materials in the furnace to melt them, the induction being created by the inductive circuit (1, 39) galvanically connected to an energy source (6), discharging the molten products form the furnace and after cooling, collecting them in a form unable to be lixiviated.
摘要:
Novel alteromonas-type bacteria capable of producing polysaccharides and differing by a certain number of parameters from known alteromonas. The corresponding polysaccharides are useful in forming gels and emulsions and are characterized by certain orginal properties, in particular, their capacity to retain ions in solution and their biological activity.
摘要:
Protéines de Mycobactérium, et en particulier de M. Bovis présentant un poids moléculaire compris entre 44,5 et 47,5 kD environ. Ces protéines peuvent posséder des poids moléculaires d'environ 45 kD ou d'environ 47 kD et des pH isoélectriques d'environ 3,7 (protéines 45 et 47 kD) et de 3,9 (protéines de 47 kD). Ces protéines ou des protéines hybrides comprenant une partie de leurs séquences peuvent être utilisées comme vaccins ou comme médicaments, ou pour la détection et le suivi de la tuberculose en particulier chez l'homme et les bovins.
摘要:
Procédé pour l'obtention de produits laitiers, en particulier de fromages, hyposodés, comprenant une étape de coagulation enzymatique du lait, caractérisé en ce qu'on incorpore un sel de magnésium au lait avant coagulation sans ajouter de chlorure de sodium.
摘要:
Procédé de préparation de chair de poisson communément appelé Surimi comprenant la combinaison d'étapes ci-après: (1) obtention d'une chair de poisson haché, (2) lavage à l'eau de cette chair, (3) essorage de la chair lavée jusqu'à obtention d'une pulpe titrant au moins 92 % d'humidité, (4) raffinage à l'état humide de ladite pulpe, (5) décantation-centrifuge de la pulpe raffinée, sans pressage de celle-ci, jusqu'à obtention d'une pulpe titrant environ 80 % d'humidité, (6) transformation en Surimi de la pulpe. Les produits obtenus par ce procédé présentent des teneurs faibles en impuretés, en muscle rouge ainsi qu'en tissu conjonctif ce qui leur confère un aspect général amélioré par rapport aux produits conventionnels. Les produits obtenus à partir de poissons gras présentent de plus une faible teneur en matières grasses.
