Abstract: On décrit un dispositif à maquette servant à mouler un élément profilé adapté à une cavité osseuse, et un procédé de fabrication d'un dispositif prothétique devant être implanté dans n'importe quelle cavité osseuse donnée et dérivé du profil de maquette moulée. L'élément profilé moulé correspond au moins en partie à la forme d'une cavité osseuse (12, 16, 14) destinée à recevoir une articulation prothétique, la cavité comportant une extrémité proximale élargie (12) et une extrémité distale plus étroite (14), et l'élément profilé moulé permettant de modeler le profil requis de l'articulation prothétique afin d'implanter celle-ci dans la cavité osseuse. Le procédé consiste à utiliser un modèle (10) comportant une partie proximale en maquette préformée (11) s'adaptant à l'extrémité proximale (12) de la cavité osseuse, et une partie d'extrémité distale (13) devant être reçue par l'extrémité distale (14) de la cavité, ainsi qu'un sac (15) servant à enfermer au moins la partie de tête de maquette (11) du modèle. Après l'insertion du modèle dans la cavité osseuse, l'espace entre la surface externe de la maquette (11) et la surface interne du sac (15) est rempli d'une composition de moulage qui élargit le sac de manière qu'il entre en contact intime avec la surface de la paroi de la cavité dans sa partie d'extrémité proximale (12), et on laisse alors prendre cette composition. La forme moulée est ensuite enlevée de la cavité pour produire un modèle moulé à partir duquel le profil requis de l'articulation prothétique peut être modelé, le procédé consistant à suivre la forme externe du modèle moulé (22) au moyen d'un détecteur de profil (21) et à faire en sorte qu'une machine modèle le profil externe d'une articulation prothétique (24) dans une forme correspondante afin que l'articulation puisse être implantée dans la cavité osseuse.

Abstract: A collapsible plastic IV container (1) is fitted with a sealable tube (4) which is provided with a female luer connector (5). A solution of a drug that is contained in a syringe can be diluted in the IV solution without the use of a needle, by direct coupling of the male luer connector (11) of the syringe to the female luer connector (5) on the container (1) with the IV solution. After the drug has been added, the tube (4) is sealed, producing a hermetically closed container (1) with the diluted, reconstituted drug solution. Use of this method and apparatus for the reconstitution or dilution of drugs increases the safety, by eliminating the use of needles and administration ports with rubber membranes and thereby reducing the chances of inadvertent exposure of hospital personnel to hazardous drugs.

Abstract: A plastic standpipe (38) for an adjustable-height support column (36) for a chair or the like to replace the conventional metal standpipe which supports the height-adjustable device, e.g., a pressurized fluid spring (40). The novel standpipe (38) is a unitary, molded generally tubular member (42) formed of high strength, and preferably low-friction, plastic material. A plurality of circumferentially-spaced, radially-extending support ribs (68), with flexible arc-like members (72) at their inner ends, are formed on the inner wall of the tubular member (42), such that the arc-like members (72) contact the spring cylinder (52) and form a floating circumferential support ring which allows for some lateral freedom of movement of the upper end of the spring cylinder. The interior ribs perform the dual functions of guiding axial movement of the spring cylinder with flexibility during height adjustment and providing sufficient rigidity to the column to support the loads placed on it. A representative composition of the plastic material is fiberglass-reinforced nylon and an impact modifier, such as a ter polymer, comprising ethylene, acrylic acid and maleic anhydride, or a rubber-like polymer.

Abstract: An apparatus for performing capillary electrophoresis comprises a housing (37) to which a sealing and electrode arrangement (36) is fastened and a removable cassette (22) which accommodates a capillary (1) in which electrophoretic separation of a sample takes place when an electric field is applied. When performing an electrophoretic separation, the end of the capillary (1) and a tube-shaped electrode (39) surrounding the capillary (1) dip into a liquid vial containing electrolyte or sample liquid. Liquid is injected into the capillary (1) by applying pressure on the liquid in the vial. An elastomeric seal (40) around the capillary (1) is provided to prevent escaping of the pressure during injection. The end of the capillary (1) depending from the cassette (20) is introduced through a funnel (41) and a central bore in the seal (40). When the cassette (20) is pressed downwards onto the funnel (41), the elastomeric seal (40) is squeezed so that the capillary (1) is sealed off. Since the seal (40) is arranged in the housing (37), no sealing is required in the cassette, resulting in a simpler construction of the cassette and facilitating replacement of the capillary in the cassette.

Abstract: Method for the preparation of a magneto-optical recording medium consisting of a transparent plastic substrate plate and layers successively formed thereon including a first dielectric layer, recording layer, second dielectric layer and reflecting layer by the sputtering method. Prior to the formation of the recording layer, the first dielectric layer on one surface of the substrate and a moisture release-preventing layer on the other surface of the substrate, which effectively prevents release of moisture from the plastic substrate are formed, which otherwise adversely affects the recording layer by oxidation, so that the time-consuming drying treatment of the substrate plate can be omitted to greatly improve the productivity of the recording media.

Abstract: Process for broadening the frequency response band of a voltage-controlled crystal oscillator (VXCO) to be inserted in a phase-locked loop (PLL) used for recovery of the clock signal from a string of data transiting on optical fibre. The process consists primarily of low-pass filtering of the control signal of the VCXO and using the filtered signal to control the VCXO and a phase modulator to which arrives the signal generated by the VCXO. The cut-off frequency of the filter and the gains of the VCXO and modulator have values such that the output signal from the modulator consists mainly of the signal generated by the VCXO, as long as the frequency response thereof holds constant, or of the signal generated by the phase modulated VCXO, otherwise. The circuit which achieves the above process is also described.

Abstract: A contour is determined in the X-ray image by means of an image processing unit (13) in an X-ray examination apparatus (2,5) so that arithmetic means (16) can determine the position of absorbing diaphragm slats (24,25;26,27) which enclose a minimum area situated around the contour. The diaphragm slats are moved to the correct position by way of a drive unit (17). As a result, overexposure of the X-ray image intensifier tube (5) is counteracted and the medical details in the image become more distinct. Image harmonization can be realised by using X-ray absorbing wedges (43-46), arrangement of the wedges in excessively light parts of the X-ray image enables the dynamic range to be increased at areas of interest. The position of the wedges is calculated on the basis of a dose calculation based on an exposure time and the voltage and current applied to the X-ray source (2), said quantities being applied to the arithmetic means  via  a control unit (15).
