Title: Security document with embedded security element with visually and mechanically verifiable distinguishing signs.
Inventor: KAULE WITTICH
IPC: G07D7/20
Filed: 1990-05-11
Abstract: PCT No. PCT/EP90/00765 Sec. 371 Date Mar. 7, 1991 Sec. 102(e) Date Mar. 7, 1991 PCT Filed May 11, 1990 PCT Pub. No. WO90/13878 PCT Pub.

Abstract: A photo-curable resin laminate composed of a support and a photo-curable resin layer on one of the surfaces of the support, wherein the photo-curable resin layer has: (a) a viscosity of 10⁴ to 5 x 10⁵ P at 90°C, (b) a thickness of 30 to 150 µm, and (c) an UV transmissivity of 40 to 95 % at a wavelength of 365 nm. This photo-curable resin layer is laminated under pressure on both surfaces of a metal-coated insulating plate having small through-holes having a 0.5 mm or smaller inner diameter in such a manner that the side of the photo-curable resin layer comes into contact with both surfaces of the metal-coated insulating plate, the photo-curable resin layer enters partially inside the inner peripheral edge of the open portion of each through-hole so as to define a photo-curable resin layer extending from this edge along the inner wall of the through-hole in a predetermined depth on the inner wall surface. The curable resin layer which is in close contact from the inner peripheral edge of the opening of the through-hole to the inner wall is formed by exposure and development to give the coating of the opening of the through-hole free from any coating defect. When an unnecessary conductor layer other than the conductor layer of a desired pattern is thereafter removed with an etchant, a printed wiring board having the small diameter through-holes and extremely high reliability of conduction between both surfaces by the through-holes can be produced.

Abstract: Un canon à électrons (40) comprend une cathode (41) et trois électrodes (42, 43, 44) plates espacées successives. Chaque électrode comprend une ouverture (45, 56, 58) alignée avec une ligne (x-x) normale par rapport à un point de la surface d'émission (58) de la cathode. Une alimentation (60) applique des tensions respectives (Vc, V1, V2, V3) à la cathode et aux trois électrodes. Les électrons sortent de la surface d'émission en un flux essentiellement laminaire et sont focalisés sur un point de croisement (59) situé au-delà de la troisième électrode, une fois que les électrons ont été accélérés jusqu'à leur vitesse maximale. La vitesse des électrons au point de croisement est sensiblement supérieure à celle atteinte avec des canons de l'état antérieur de l'art. Le point de croisement a une résolution accrue à cause de la réduction de l'effet de charge d'espace. Le point de croisement reste à un endroit essentiellement fixe par rapport à la surface d'émission à tous les niveaux du courant de faisceau. Un procédé amélioré d'exploitation d'un canon à électrons comprend la commutation dynamique des différentes tensions appliquées à la cathode et aux trois électrodes, de façon à maintenir la résolution d'un point d'image reformé sur l'écran dans une largeur de bande prédéterminée dans toute la plage possible de courants de faisceau.

Title: Method of producing fusion proteins.
Inventor: GILLIES STEPHEN D
IPC: C07K16/30
Filed: 1990-08-01
Abstract: Disclosed are methods of producing fusion proteins including those with dual biological activities. These methods include the provision of first and second DNA sequence encoding a first and second polypeptide, respectively, the digestion of the first DNA sequence at a restriction site adjacent its 5' terminus, and the ligation of a linker/adapter sequence (1/a) to the restricted end of the first DNA sequence, thereby forming a cassette. The 1/a includes, at one end, that portion of the first DNA sequence extending from its terminus nearest the restriction site to the restriction site, and at the other end, one side of a splice site. A eucaryotic host cell is transfected with the cassette and the second DNA sequence having, at one end, one side of a splice site compatible with the side of the splice site on the 1/a. The transfected host cell is cultured to express the transfected DNA as a single chain fusion protein. <IMAGE>

Abstract: The flexographic printing machine, in particular a single-cylinder flexographic printing machine, is provided in a coaxial arrangement with its main drive central gear (12) towards the outside of the machine with a second independently rotatable auxiliary gear (22) with the same toothing, the gap between the auxiliary gear (22) and the central gear (12) being smaller than the width of the impression cylinder gear (14). Provided for this separate auxiliary drive track (Z) is a dedicated drive (25) which can be operated independently of the main drive (21) of the printing machine and thus independently of the main drive of the back pressure cylinder (2) and of the printing units. Since this auxiliary drive can, on the one hand, be stopped independently of the main drive and, on the other hand, be driven up to a synchronous speed with the central gear (12) for all machine speeds, it is possible to disconnect or add any desired number of printing units during running production. A partial pattern change is thus possible in running production with a minimum time requirement and a minimum of waste paper, but even when used on tandem printing machines a change in format is possible virtually without stoppage of the machine and production. <IMAGE>

Abstract: A process for forming a prosthesis related to bone structure internal to a body using CT scan data corresponding to the radiological density of the bone structure to derive the inner and outer bone surface contours. The density and the density gradient of discrete points in the bone structure is compared to threshold density levels and to threshold density gradient levels and points are selected to form a series of interim outer contours. A contour shape factor is derived for each interim outer contour, and that interim contour is chosen in which the contour shape factor is maximum denoting less fluctuations in the contour circumference. The bone surface contour data is used to develop a graphic model from which a set of digital data is generated for a surface model representing the graphic model. A set of numerical control machine instructions are generated to make the prosthesis.

Abstract: A fluid controller (11) is disclosed for controlling the flow of fluid from a source (73) to a steering cylinder (77), especially for use on large, articulated vehicles. The controller includes a fluid meter (17) and a valving arrangement including a spool (33) and a sleeve (37). The housing and the valving define a main fluid path (113) including a main variable flow control orifice (A1), and the fluid meter (17) in series flow relation between an inlet port (23) and the first control fluid port (27). In accordance with the invention, the main variable flow control orifice is formed by a first fluid passage (93R; 123L) defined by the spool, being in fluid communication with a first fluid port means (101R; 131R) defined by the sleeve. The first fluid port means extends circumferentially to provide continuous fluid communication between the inlet port and the first fluid passage of the spool, as the spool rotates relative to the sleeve from the neutral position to the first operating position. The relative rotation of the spool and sleeve extends at least about 45 degrees, and in the subject embodiment, extends about 60 degrees. The substantially greater rotational displacement between the spool and the sleeve substantially reduces the incidence of lateral jerk without the need for a cushion valve or an accumulator within the system.

The drill shaft passes through an interior passageway connected to the aspiration conduit and the irrigation conduit is connected to an annular passageway concentric to the interior passageway. The drill head can be inserted into contact with the cataract through an opening in the capsule surrounding the lens and as it rotates it churns the cataract material into an emulsion which is aspirated, along with irrigation fluid from the vicinity of the rotating drill head.
