摘要:
The reusable cartridge assembly for dispensing at least one component comprises at least one cartridge cylinder (20A, 20B, 43A) having a rigid wall, a cartridge outlet having an outlet tube and a package assembly (11A, 11B, 42A), the package assembly comprising at least one container having a thin, flexible membrane wall with an open end and a front outlet (5, 5A; 47) to which the open end (15, 44E) of the flexible membrane wall (12, 44) is secured, said front outlet having an outlet tube (4, 51). The open end of the flexible membran wall (12) is secured by a ring-shaped sealing element (6, 6A, 6B, 34) to the front outlet tube and the closed back end of the membrane container (12) has, at it's center, a compressible plug (14) and a closure element (13) over it's outer diameter. This membrane container outlet end allows conventional filling of the container and a perfect seal at the front outlet (5).

Le moteur électrique (1) fait partie d'un ensemble comportant deux connecteurs (5, 6) posé sur le moteur. Les connecteurs (5, 6) sont muni de conducteurs (8, 9) surmoulés ou sertis et des broches (10, 11, 12) pour établir le contact électrique entre le moteur, un câble de commande et d'alimentation et un circuit électronique associé au moteur. Le montage de l'ensemble est réalisé par simple pose des connecteurs (5, 6) sur le moteur (1).
摘要:
A device for packaging a chip shaped carrier having an active surface which is adapted to be read by an electro-optical reading device, e.g. a surface which carries an array of DNA oligonucleids. The device comprises: a cartridge (12) having an opening (13) for receiving a liquid sample and including casing parts (14, 15); a casing part (14) having an inner surface (16) and outer surface (17), a first cavity (18) for receiving a chip shaped carrier (21), and means (22) which provide visual access to that first cavity and thereby to the active surface of the chip shaped carrier; a sealing frame (26) which is part of a casing part (14) and which is made of a compressible material, sealing frame (26) being connected to said flat bottom surface (23) of the first cavity (18); and a locking frame (31); the shape and dimensions of first cavity (18), chip shaped carrier (21), sealing frame (26), and locking frame (31) being so chosen that chip shaped carrier (21) fits into the space delimited by sealing frame (26) and a gap (27) which exists between sealing frame (26) and inclined side wall surfaces (24) of first cavity (18), and locking frame (31) is larger than gap (27), but locking frame (31) is however insertable into gap (27) by exerting pressure on locking frame (31) against casing part (14), that pressure causing a compression of sealing frame (26) and a corresponding pressure on a substantial part of the outer surface of the lateral periphery of chip shaped carrier (21), which outer surface is in contact with sealing frame (26).
摘要:
The method includes disintegration of the initial information into separate streams, coding each stream as a sequence of signals and transmitting the signals of each stream to the separate fixed areas situated on the integument of a person forming in total skin sensitive information zone, the function of coding being cyclically changed in the process of conveying information, i.e. conveying the visual information is carried out with electrical signals discretely frame by frame with cyclical frame by frame changing the dependence of current intensity and/or voltage of signals from the brightness of corresponding fragments of the frames ensuring integration of perceiving frames within the limits of a cycle with choosing time characteristics of the cycles; the dependence of current intensity and/or voltage of the signals from the brightness of the corresponding fragment is direct in a part of the cycle (positive frames) and is inverse in the other part of the cycle (negative frames), the number of the positive cycles can be more or less than that of the negative ones, the frequency of the signals' current in the negative and positive fragments of the cycle may be different.
摘要:
A thermal cycler for performing amplification of nucleic acids, comprising
(a) a thermal block (71) having a plurality of chambers; (b) a movable cover (14) having heating means (15) positioned within it; (c) transport means for moving said cover (14) from said first position to said second position and viceversa, the path followed by the cover (14) comprising: a first path segment which lies above and at a predetermined distance from said thermal block (71) and along which said cover (14) is moved towards a stopper (16) until it abuts against it and a second path segment along which said cover (14) is moved away from said stopper (16) and downwards until it is vertically aligned with said thermal block (71) and exerts a predetermined pressure on reaction vessels (13) positioned in said chambers (72) of said thermal block.
