Abstract: A color printing arrangement has a series of printing stations in each of which a different color is imprinted upon predetermined regions of a travelling band to form color images. A device for measuring the width of the band by sensing the edges thereof is located immediately upstream of each printing station. The width of the band at the first printing station is compared with the width at each of the following printing stations. As long as the widths at the latter printing stations are the same as that at the first printing station, the band is allowed to continue travelling unchanged. However, when the width of the band at a printing station downstream of the first printing station differs from the width at the first printing station, the band is operated upon to return the width to its original value. The reason is that a departure from the original width of the band causes the predetermined regions which are to be imprinted to be moved out of alignment with the printing devices in the printing stations. By returning the width to its original value, the alignment of the predetermined regions is restored.

Abstract: The sports shoe, in particular for use for long-distance runs on hard and/or uneven tracks, roads or the like, is to be designed in such a manner that a sufficient support effect is ensured in the inner region of the shoe even with inclined and/or cambered tracks, roads or the like, that the feeling of the track contact is thus guaranteed even with such unfavourable but nevertheless very common track conditions. To this end, it is envisaged that outsole regions of different flexibility are present only in the heel (4) and possibly also in the ankle (9). In this connection, the arrangement is made in such a manner that the heel region and possibly also the ankle region (4, 9) begin with lower flexibility on the inside (14) of the outsole (2) and extend at most as far as the central plane (13) of the outsole, which runs through the longitudinal axis (11) of the sole. <IMAGE>

Abstract: A transport system is provided in which a plurality of samples (SA) are introduced into a carrier stream flowing through a conduit (20), whose inner surface is coated with an immiscible liquid film (F). The carrier stream can be a sequence of alternating gas (A) and liquid (W) segments which are in direct contact with each other and, thus, not individually encapsulated by the immiscible liquid. Samples are introduced at various points along the conduit and, thus, the system allows for the collection and transport of samples from a plurality of remote locations to at least one central receiving station where they can, for example, by analysed. Carryover between successive samples to be transported is effectively eliminated.

Abstract: A friction welded fastening system comprises a thermoplastic fastener 40 having a primary fastening element 42, a base 44 carrying the fastening element 42, and having a surface 46 arranged to be fused to a workpiece by the heat of friction generated by the application of rotational and axial forces to the fastener when its base surface is in contact with the workpiece; and an application tool 10 for rotating and applying axial pressure to the fastener 40. Such a system includes means automatically to stop rotation of the fastener 40 when its base surface 46 has been heated to a predetermined degree to enable it to fuse to the workpiece. The means automatically to stop rotation of the fastener 40 comprises at least one heat-sensitive protrusion 50 adjacent the base surface 46, and at least one projection 19 on the tool 10. One of the protrusions 19 of the tool 10 engages the projection 50 on the fastener 40 to rotate the fastener 40 until the base surface 46 has been heated to a predetermined degree and then the protrusion 50 reaches a predetermined minimum strength at which point it yields under the applied load from the projection 19 of the tool 10 and the fastener 40 then stops rotating.

Abstract: Un protecteur de surtension est utilisé dans un appareil ayant deux pièces mobiles (1, 5). Les pièces sont en communication mutuelle par l'intermédiaire d'un palier (2, 3, 4), une pièce étant stationnaire par rapport à une sous-structure (13) à un potentiel électrique de terre. La partie mobile (5) peut être soumise à une tension et la partie stationnaire (1) est connectée électriquement à la sous-structure mise à la terre. Pour empêcher qu'un courant ne passe au travers du palier entre les pièces, un dispositif d'isolation électrique (6, 7) est monté dans le chemin d'écoulement du courant pouvant avoir lieu au travers du palier suite aux différents potentiels des pièces. La pièce mobile (5) possède une protubérance (9) à une distance d'un dispositif (8) connecté électriquement à la terre de sorte qu'un écartement de décharge d'étincelle (10) est formé entre les parties en mouvement relatif. Les paliers (2, 3, 4) sont protégés contre le courant par le dispositif d'isolation électrique (6, 7) jusqu'à un seuil de tension donné. De manière à ne pas dépasser ce seuil de tension, l'écartement de décharge d'étincelle (10) entre en fonctionnement à une valeur inférieure à ce seuil de tension et maintient à cette valeur inférieure la différence de tension entre les pièces.

Abstract: A positive photoresist metal ion aqueous developer is provided that gives a high contrast to the photoresist. 
     The developer disclosed comprises a formulation of aqueous alkali-base such as potassium hydroxide and a fluorocarbon surfactant. The incorporation of the fluorocarbon surfactant provides the unexpected increase in the contrast of the photoresist. The addition of the fluorocarbon surfactant increases the gamma from a typical photoresist gamma (y) of 3 or less to a gamma greater than 10. 
     The high contrast photoresist provides linewidth control and affords improved process latitude in photoresist imaging. The linewidth control is particularly critical in cases where fine lines are to be defined in the resist that covers steps or topography on the coated substrate. The higher the contrast, the less affected the resist by the topography, provided the exposure is adequate to expose the resist. The process latitude afforded by the high contrast is a result of the ability to over develop (develop longer) the exposed resist without affecting the unexposed resist in the adjacent areas.

Abstract: O A light three-wheeled vehicle has a single front wheel (31) supported on one side thereof by a single support supporting member (32). 
     The single front wheel (31) is included in a front body structure (34) to which there is connected, by a swing joint (38), a rear body structure (35). 
     The tendency of the vehicle to incline during running is reduced, and rectilinear running of the vehicle is achieved, notwithstanding the unbalanced weight of the steering structure resulting from supporting the front wheel (31) on one side only through a single support, by offsetting the front wheel (31) to one side of the centre line (N 3 -N 3 ) of the vehicle, being the same side as the supporting side of the supporting member (32) with respect to the centre line (N 3 -N 3 ), on which centre line the centre of gravity (G e ) of the rear body structure (35) lies.

Abstract: A signal is generated for producing a video display carrying superimposed images, at least one of which is derived from a system for detection of non visual signals, such as an ultrasonic or eddycurrent inspection device, or a backscatter detector of penetrating radiation. Accurate registration of the superimposed images is achieved by providing for the system for detection a moveable probe indicating the location of inspection by the detector system, a point source of light or other radiation to which a video camera (II) responds on the probe which point source is 'on' when the detector response is positive, and a comparator (14), and memory (16) system in which is built up a store of all bright points corresponding with those where the camera observed the point source 'on'. The memory stored bright points are mixed with the camera video signal to give the superimposed image.
