On réalise un mammographe dans lequel le tube 2 à rayons X et le plan 1 de travail sont maintenus en vis-à-vis l'un de l'autre par un étrier 21, 22 permettant un accès aisé d'une opératrice sur le sein à radiographier. L'étrier 22 a une forme de couronne circulaire et est susceptible de tourner sur lui-même en coulissant sur une couronne 21 complémentaire de manière à réduire l'inertie des mass...

The mechanical strength of structural adhesive joints to the formation of microcracks is increased by exposing the adhesive joint to controlled accelerated ageing at a temp. below the glass transition temp. of the adhesive and in a humid environment having a relative humidity of greater than 40%. USE/ADVANTAGE - The ageing treatment relieves concentrations of strain existing e.g. in heat cured epo...

A lifting mechanism for the pressing roller of the feed mechanism of a crusher for scrap. The rotor of the crusher, via a lifting mechanism that acts upon a mounting bracket of the rotor mounting, can be removed from a split housing after an upper part of the housing has been raised about a horizontal pivot axis and has been secured in position relative to a lower part of the housing, whereby pivo...

L'invention concerne un procédé et une installation pour la commande automatique d'un véhicule guidé 2, et propose un nouveau concept de sécurité qui empêche, en cas d'urgence et/ou de défaillance, que le véhicule soit stoppé dans des tunnels, sur des ponts ou dans des terrains impraticables. L'invention réside en ce que le véhicule, entre des zones d'arrêt présélectionnées 11, 12, 13, munies d...

Mécanisme d'alimentation pour une machine à photocopier ou similaire, qui dirige le support de copie 12, notamment un support de grand format, dans un plateau récepteur 30 le long d'un trajet 32 sensiblement parallèle au trajet initial du support, mais dans la direction opposée. Ceci permet l'enlèvement du support par le devant de la machine à photocopier. Le bord avant du support est amené dir...

A device for discontinuing and automatically restoring the operational function of a spring brake actuator comprises a piston (9) with a piston rod (10) and a spring (13) actuating the piston and piston rod in a working direction for brake application at falling brake fluid pressure on the piston, a slitted, resilient locking ring (15) being arranged in grooves (16, 17) facing each other in the pi...

A read/write storage system for reading/writing data to and from a flexible optical or magneto-optical media (disc or tape eg helically scanned by rotating drum) includes an optical read/write head and a fine movement stabilizer 64 positioned proximate the flexible media for stabilizing the flexible media in a desired position so that the optical head providing focussed light need not be moved sub...

A process for packaging a product, including the steps of applying a foamed composition to the product to be packaged; and encasing the product in an outer package. The foamed material can be applied in liquid or semiliquid form at a point-of-contact temperature less than about 54 DEG C and solidifies substantially on contact. The foamed material is, preferably, applied selectively to cover the s...

Bol centrifuge travaillant en continu pour concentrer des substances solides en suspension, dans lequel les substances solides concentrées sont dirigées depuis une enceinte à produit solide extérieure du bol, par l'intermédiaire de canaux, dans une chambre intérieure du bol centrifuge, à partir duquel les substances concentrées peuvent être extraites en continu. Une enceinte de rejet à vortex 5...

Le système de traitement des expéditions de paquets comporte un ensemble de mémoires 2 dites fichiers d'une part contenant des identifications de transporteurs, d'expéditeurs, de services de chaque transporteur, de documents devant accompagner chaque expédition et d'autorisations de chaque expéditeur en regard des transporteurs et des services, et d'autre part recevant des caractéristiques rela...

L'invention concerne un système de mémorisation par lecture/écriture, destiné à lire et écrire des données, pouvant être détectées optiquement, sur un support optique ou magnéto-optique souple.

Il comprend une tête de lecture/écriture optique pouvant être amenée par un bras 30 au-dessus d'un support souple sur lequel elle applique une lumière focalisée et de laquelle elle reçoit la lumièr...

Liquid bitumen at a temperature of 120 - 160C is mixed with 1-3% by weight of water in a mixing device (8) at a pressure which is higher than the saturation pressure of water vapor at the temperature of the hot bitumen. From the mixing device the mixture is allowed to expand through a valve (10) such as a throttle valve, the resulting evaporation of the water in the mixture causing the desired ...

An appts. for filtration and purificn. of fluids, esp. liqs. such as water, by means of membranes or by tangential filtration and an adsorbent, esp. active carbon, operates as a sealed loop circuit, with the adsorbent being introduced into the stream of fluid to be treated and fed with this to a filtration unit comprising at least one membrane or a tangential filtration unit, through which part of...
