Abstract: Multilayer structure comprising, in sequence, metal or metallized substrate layer (5), layer of polypropylene-based binder (6) extruded at speed higher than 100 m/minute and optional polypropylene layer (2), is new. The binder layer (6) is rendered non-separable from metal/metallized layer (5) by thermal treatment, but it can be peeled off polypropylene layer (2). Multilayer structure comprising, in sequence, metal or metallized substrate layer (5), layer of polypropylene-based binder (6) extruded at speed higher than 100 m/minute and optional polypropylene layer (2), is new. The binder layer (6) is rendered non-separable from metal/metallized layer (5) by thermal treatment, but it can be peeled off polypropylene layer (2). Thermal treatment rendering layers (5) and (6) non-separable can be conducted using infra-red irradiation, or by passing through a hot air tunnel, or by induction method, to bring metal layer (5) to temperature higher than that of melting point of binder layer (6). The layer of binder (6) is sandwiched between metal layer (5) and polypropylene layer (2) whose melting point is higher than that of binder, and the structure can be peeled off using force of separation between layers (6) and (2) equal 8-15 N/15 mm. Independent claims are also included for (1) a lid (4) (of bowl or box -shaped container), comprising structure as claimed, where the metal of metallic or metallized substrate layer is aluminum; (2) container made of polypropylene or polypropylene-coated material and closed with lid (4) as claimed; and (3) container made of structure as claimed (both containers sterilizable and resistant to food acids, fats and technical solvents.

Abstract: L'invention concerne des méthodes et compositions de production d'ADN complémentaire simple brin dans des cellules eucaryotes et plus particulièrement une cassette d'ADN produisant un ADN complémentaire simple brin in vivo. La cassette contient le gène codant une transcriptase inverse du virus de leucémie murine de Moloney/ribonucléase H, un gène endonucléase de restriction bactérienne et une séquence intéressante produisant une matrice d'ARN à partir de laquelle la transcriptase inverse synthétise un ADN complémentaire simple brin d'une séquence particulière. On modifie ensuite l'ADN complémentaire simple brin pour retirer toutes les séquences de vecteurs flanquantes en profitant de la structure  </=  souche-boucle >/=  de l'ADN complémentaire simple brin qui se forme suite à l'inclusion d'une répétition en tandem inversée qui permet à l'ADN complémentaire simple brin de se replier pour former une souche d'ADN double brin dans la séquence intéressante. La souche double brin contient un ou plusieurs éléments génétiques fonctionnels tels qu'un site de reconnaissance d'endonucléase de restriction et la boucle, qui reste comme un ADN complémentaire simple brin, est composée de n'importe quelle séquence nucléotidique voulue. Cette configuration permet à la souche double brin de la souche-boucle intermédiaire d'être clivée par l'endonucléase ou les endonucléases de restriction correspondants spécifiques du site dans la souche, et la boucle, ou séquence intéressante, est ensuite libérée comme une partie d'ADN linéaire, simple brin. Cette partie d'ADN simple brin libérée (ou clivée) contient des informations de séquences minimales, s'il en est, en amont à 5' ou en aval à 3' à partir de la souche double brin antérieure qui contient le site de coupure d'endonucléase de restriction. L'utilisation de ce système pour produire de l'ADN simple brin dans des cellules hôtes est illustrée par les transfections in vivo réalisées grâce au système vectoriel d'ADN selon l'invention.

Title: Electrical connector capable of exerting a selectively variable contact force
Inventor: HAMILLA BRIAN J
IPC: H01R13/115
Filed: 2001-05-15
Abstract: An electrical connector for mating with a male contact of a mating connector is capable of exerting a selectively variable contact force. The electrical connector includes a conducing member having a lead and a contact beam electrically coupled to the lead. The contact beam is adapted to resiliently engage the male contact. The electrical connector further comprises a contact housing. At least a portion of the lead is disposed within the contact housing. At least a portion of the contact beam is disposed within the contact housing so that the contact beam is urged into and restrained by the contact housing when the contact beam resiliently engages the male contact. A contact force is thereby generated between the contact beam and the contact pin. The contact housing is capable of being selectively positioned in relation to the contact beam so that a point of restraint on the contact beam is selectively variable. The contact force between the contact beam and the male contact can thereby be varied on a selective basis.

Abstract: There has been explained a composite, particulate feed for fish larvae or fry, and larvae of other aquatic organisms. This dry feed, so-called formulated feed, shall be of such a high quality and condition and otherwise exhibit such properties as to make it suitable for replacing live feed (for example Artemia Salinas), which is very expensive and which may be hard to obtain, at least periodically, and which has a generally very low percentage of hatching (Artemia Salinas) some years. To this end a feed according to the invention excels in that the feed particles consist of a matrix containing water-insoluble nutrients, phospholipids/biomembranes being embedded in said particles, which biomembranes contain fat-soluble components and pack water-soluble nutrients. Also, there has been explained a method of manufacturing such feed, whereby a matrix material which contains water-insoluble nutrients, phospholipids/biomembranes containing fat-soluble and water-soluble nutrients, further nutrients and water is mixed together, comminuted in a nozzle or similar and then cross-linked in a suitable solution.

Abstract: A differential displacement electromagnetic device providing forward thrust over water of a watercraft. This electromagnetic device includes an elongated rigid rail member anchored against the watercraft bilge, a first magnet module, slidingly carried by one end portion of the rail member, and a second magnet module, slidingly carried by another end portion of the rail member. The second module has the same mass as the first module but has a pivot mount at a central portion thereof. A pair of elongated rigid arms are pivotally mounted at their inner ends to the second module member pivot mount, while a pair of electromagnets are fixedly mounted to corresponding outer ends of the rigid arms. An electric battery generates an electromagnetic field of force about the magnets and electromagnets, such that upon energizing the battery, magnetic repulsive sliding displacement of both modules occurs, wherein the speed achieved by the second module is greater than that of the first block so that forward thrust of the watercraft over water may occur.

Abstract: A cell-based assay is provided for screening substances for the capacity to inhibit COX-2 activity. The assay utilizes as a screening reagent a cell line which has been engineered to achieve constitutive or inducible expression of COX-2. In one embodiment, the cells express a GTPase-deficient, constitutively-activated mutant form of the .alpha.-subunit of protein G12 which induces the production of arachidonic acid and COX-2. Decreased cell proliferation in the presence of test substance indicates that the substance has COX-2 inhibitory activity.
