Abstract:
A long-term storage container (1) for storage of radioactive material to inhibit radioactive radiation therefrom to the outside of the container, the top of said container to be closed by a screw-on radioactive radiation inhibiting lid- (7), said container having an integral inner container part (2; 34; 62; 62') of a first material, e.g. plastic material, an integral outer container part (3; 43; 69) of a second material, e.g. plastic material, and radioactive radiation inhibiting material (4; 38; 68) in an inter-space between the walls and bottoms of said inner and outer container parts. To fill the inter-space an inter-space container part (4; 38; 68) is integrally moulded through injection or pressure moulding and then fitted onto the inner container part (2; 34; 62; 62') to subsequently mould the outer container part (3; 43; 69) onto the outside of the inter-space container part (4; 38; 68). A specially made container lid (7) is provided. A preferred twin-mould moulding apparatus (61) provides for simultaneous pre-casting of the inner container part (62') and the outer container part (69) in a respective mould of the apparatus.
Abstract:
A method, and apparatus for performing the method, is provided for the purpose of forming and inserting seal pieces into a container cap of a type which comprises an integral cup-like member having a top panel, a skirt depending from the top panel, and a plurality of cap lugs formed in the rim and extending partially inward from the rim. A quantity of such caps is supplied onto a surface, preferably with the caps inverted resting on their top panels. The caps are gathered into a plurality of rows and forwarded to screw conveyor mechanisms for advancing the caps to seal inserting stations located substantially coplanar with said assembly surface. The screw conveyor mechanism includes a table with at least two slots therein and conveyor screws extending beneath and along the slots and carrying caps along the table to a discharge location where the caps are temporarily located. A supply strip of flexible seal material is directed into proximity to the inserting stations and precisely cut seal pieces from the strip are inserted into the caps.

An apparatus for performing this process is also provided. By the process and apparatus of the invention sealed vials with a sterile interior may be made.
Abstract:
A dispensing system (10) for use in an area of interest (12), the system comprising at least one device (18) for sanitize conditioning a medium, a sentry (14) for detecting an object and for communicating with the at least one device (18), the sentry (14) itself comprising a detector (24) for detecting the object and a controller (26), operatively coupled to the detector (24), for maintaining a count of the number of objects detected by the detector (24), wherein the controller (26) transmits one or more variables, based on the count, to the at least one device (18) to cause the at least one device (18) to sanitize condition the medium in accordance with the one or more variables.
Abstract:
A method of forming a metallic container (14) by placing body and lid portions (10,12) together, keeping parts of the body and lid portions in contact with one another, and vibrating the lid with respect to the body, thereby generating frictional heat to form a friction metallic weld therebetween. Apparatus for attaching the lid and body portions of the metallic container includes a body supporting base (18) , an assembly (24) to support a flange of the body, a sonotrode (32) to contact a flange of the lid so that wherein the flanges of the lid and body are held together between the support assembly and the sonotrode. A motor (52) vibrates the sonotrode relative to the support assembly to thereby move the flanges relative to one another generating sufficient frictional heat to create a friction metallic weld therebetween.
Abstract:
Procédé de production d'un réservoir, notamment un réservoir cryogénique, comportant deux enveloppes concentriques (1, 3) respectivement intérieure (1) et extérieure (3) délimitant entre elles un espace inter-paroi (2) destiné à être soumis à une pression de travail dite basse, l'enveloppe intérieure (1) étant destinée à être soumise à une pression de service interne positive, le procédé comportant : - une première étape calcul d'au moins une dimension minimale caractéristique de l'enveloppe intérieure (1) pour satisfaire au moins une première contrainte de sécurité, - une seconde étape calcul d'au moins une dimension minimale caractéristique de l'enveloppe extérieure (3) pour satisfaire au moins une seconde contrainte de sécurité, - des étapes de fabrication des enveloppes intérieure (1) et extérieure (3) satisfaisant respectivement aux dimensions minimales calculées lors des première et seconde étapes de calcul, caractérisé en ce que la seconde contrainte de sécurité est la tenue en pression et la résistance à l'éclatement de l'enveloppe extérieure (1) pour la pression de service prévue pour l'enveloppe intérieure (1) selon au moins une norme ou un code de construction.
Abstract:
Zum Herstellen von Dosenkörpern (24') mit einem Dosenmantel (24) und einem bei einer Stirnseite des Dosenmantels (24) festgesetzten Abschlusselement (31b, 32, 31a) wird ausgehend von einem Metallband (1) mittels eines Umformschrittes, gegebenenfalls mindestens eines Schneidschrittes, und eines kontinuierlichen Schweissschrittes ein Rohr (11), gegebenenfalls aus direkt aneinander anschliessenden Abschnitten (112), hergestellt, von dem dann Abschnitte als geschlossene Mantelflächen für Dosen verwendet werden. Die Abschnitte werden von einer Mantelformvorrichtung so geformt, dass Dosenmäntel (24) bereitstehen, an denen ein Abschlusselement (31b, 32, 31a), insbesondere ein Dosenboden (31b), eingesetzt werden kann. Beim Schweissschritt kann die Dosenlängsnaht (11a, 124) im Wesentlichen als ununterbrochene Naht mit grosser Präzision kostengünstig und mit einfachen Anlagen hergestellt werden.
Abstract:
A method and apparatus are disclosed for detachably joining two members (21/22; 51/52) at a plurality of points along their corresponding edges (23/24; 53a/54) and without longitudinal displacement of these edges during and after closure of the joint. A movable wedge means (44; 61) is advanced between pairs of force receiving points (35-38/41, 42; 55, 58) connected to each of the two members. As the wedge means is advanced in the apex direction, the pairs of points are forced apart and, in direct response, the corresponding edges are drawn together. Variations on two fundamental embodiments are disclosed, one is linear and the other is circular. In the linear embodiment, two doors, panels or bars are joined. In circular embodiments, round tubes or rods are joined or a circular cap is secured to a container or enclosure. The invention may also be embodied in kits for joining linear or circular members. In other embodiments, a gasket material (59) and/or other component is placed and retained between the corresponding edges.
Abstract:
A method and apparatus for covering and identifying a container utilizing a thin film material and a frame. The thin film material covers a through hole in the frame and has a perforation that defines an outer detaching surface an inner covering surface commensurate with the container opening. The method comprises the steps of attaching the thin film material to a frame having the through hole; disposing the frame onto an open top surface of the container; depressing a portion of the frame to detach the thin-film from the frame along the perforation and further sliding the frame coaxially to circumscribe the base of the container where it identifies information about the container.
