摘要:
An X-ray inspection system in which a thin X-ray absorber is placed upstream of an object under investigation so as to remove low energy X-rays, typically below 0.5MeV. The absorber may be a sheet of lead 10mm thick. Where the X-ray inspection system which incorporates a detector which relies on the electro-magnetic cascade effect produced in suitable materials when bombarded with X-rays so that energy is transferred into the material at different depths depending on the energy of incident X-rays, and the first component on which the X-rays impinge comprises a relatively thin crystal this unwanted background may be reduced by placing a vessel containing a fluid whose density is less than that of air, in front of the detector crystal array. Typically the fluid is helium at atmospheric or slightly greater than atmospheric pressure. The background can be reduced by applying a magnetic field in the region in front of the detector crystal array so as to sweep away electrons from that region.

The invention relates to a shredder device intended to be connected to a toilet bowl, which consists of a vessel (1) into which the water and matter from said toilet bowl are conveyed and in which there is a motor (3) equipped in its upper part with a disintegrating means (5) contained in a basket (4) and at its lower part with a pump (7), said motor (3) connected to a capacitor (12) and a miniswitch (11) being switched on by a membrane-type pressure switch that controls the miniswitch, in which shredder device the control unit (10) is situated underneath an access hatch formed in the lid (2) of said vessel and closed by a removable cover (8) and the miniswitch (11) and the capacitor (12) are accessible at the top of the control unit (10) and/or the motor/pump/disintegrating means assembly (3,7,5,6) is situated under an access hatch formed in the lid (2) of said vessel and closed by a removable cover (8a). This shredder device through its design offers ease of intervention by non-professionals in the event of breakdown.

The invention relates to a dryer that comprises a lower tunnel (110) and an upper tunnel (120) connected at each end by a well (130, 140) and through which extends a chain conveyor (150) with baskets (155) for receiving the products to be dried. The chain (150) goes from a horizontal path to a vertical path (or conversely) at the junction of a tunnel (110, 120) or a well (130, 140) by angle transmission (151-154) and at a well (130, 140), the transmission pulley (151A-154A) at the end of the horizontal path is completed by a bypass pulley (151B-154B) installed in the well so that the chain follows an inclined path substantially corresponding to the hypotenuse of the triangle taken in the rectangle having a vertical side equal to the height of the basket (155) up to the suspension point to the chain (150) and a horizontal side equal to half the width of the basket (155).

L'invention concerne un procédé de détermination de la présence de pectines dans une solution aqueuse, caractérisé en ce que :
a) un échantillon de ladite solution aqueuse est mélangé avec de l'acétone dans un rapport en volume allant de 1:10 à 10:1, b) le nombre de phases du mélange obtenu est ensuite déterminé. Un colorant spécifique des pectines peut être ajouté audit mélange afin de faciliter l'interprétation du résultat. Le procédé selon l'invention est plus particulièrement destiné à la détermination de la présence de pectines dans des jus de fruits, des moûts de raisins et autres liquides alimentaires, avant ou après traitement par des pectinases.
Il peut également être appliqué au criblage de micro-organismes à activité pectolytique.

Feuille bitumineuse d'étanchéité destinée à recevoir une couche d'asphalte coulé, constituée d'une armature imprégnée d'un bitume modifié par des charges et des polymères, caractérisée en ce que la face sur laquelle sera coulée la couche d'asphalte comporte une couche fusible d'un matériau fondant à une température inférieure à la température de coulée de l'asphalte en absorbant une part suffisante de cette chaleur de coulée pour empêcher la fusion du bitume sous-jacent. On utilise avantageusement une couche fusible constituée par un non-tissé de 20 à 60 g/m² en matière plastique et plus particulièrement en polyester.
