Abstract: A method for detecting flaws and surface defects in metal workpieces, particularly in non-magnetic steel workpieces. The surface of the workpiece (2) is heated by passing the workpiece is in its longitudinal direction through an induction coil (3), scanning the surface of the workpiece with an infrared camera (4) transversely across the surface of the moving workpiece immediately after induction heating and recording a streaked pattern temperature profile in which the streaked pattern repeats itself where there are flaws in the surface. An induction coil (3) is used which has a current frequency which gives a penetration depth of the induced current in the workpiece which is greater than the depth of the flaws which are to be detected. The flaws and surface defects are detected by recording a lower surface temperature than the rest of the surface of the workpiece by scanning the temperature profile immediately after induction heating.

Abstract: Un générateur de signaux vidéo met en oeuvre un sous-système de processeur central (11), un système de commande d'affichage (18), un sous-système de générateur d'affichage (20), un sous-système de mémoire de régénération (24), et un système de données vidéo (28) pour traiter des données de pixels en parallèle en vue d'obtenir des cadences élevées de fréquence de pixels permettant de grandes images sans scintillement. Pour obtenir des fréquences de pixels élevées, on maintient un traitement parallèle depuis la mémoire en mode point (36) jusqu'au traitement des données par le convertisseur numérique-analogique (54). Le sous-système de générateur d'affichage (20) produit un signal d'adresse de données numériques multibit (35) qui sert à adresser une pluralité de réseaux (36) de mémoires en mode point (BMM). Ces réseaux (BMM) (36) fonctionnent en parallèle, et les données (35) sont mémorisées dans une portion de chaque réseau BMM (37, 39) jusqu'au remplissage de ce dernier. Les données sont extraites des réseaux (37, 39) en parallèle (32) et introduites dans une pluralité de multiplexeurs de sortie BMM (MOM) (38), de nouvelles données étant mémorisées en continu dans chaque réseau BMM (37, 39). Le multiplexeur MOM (38) assure le multiplexage temporel du signal de données (32) en quartets (26), d'une quantité inférieure de bits, représentant l'intensité chromatique des signaux de données (32). Les quartets (26) sont multiplexés par une pluralité de multiplexeurs vidéo (40) en vue de produire un code d'intensité chromatique multibit qui sert à adresser une pluralité de tables de consultation chromatiques (40). Ces dernières sélectionnent les données de réseau pour affichage, et génèrent des codes chromatiques (48). Ces codes chromatiques (48) sont multiplexés à la fréquence de pixels désirée et sont introduits dans des convertisseurs numériques-analogiques (54) pour commander un moniteur (58).

Abstract: In dryers with gas heating, it is a particular problem uniformly to mix the combustion gases produced with the burner with the treatment air which is circulated in the circuit. In order to achieve this, a special construction of the air mixing device is envisaged, which consists of three parts arranged one behind another, the treatment air being in each part of different construction in each case deflected to the centre of the treatment duct and in this connection mixed with the air flows which originate from the sides. It is advantageous, firstly by means of a funnel-shaped air mixing part and then by means of such with sheets arranged parallel to one another, which are first arranged vertically and then transversely thereto, to create swirling in each case.

Abstract: The present invention involves a novel tripyrrole dimethine-derived "expanded porphyrin" (texaphyrin), the synthesis of such compounds, their analogs or derivatives and their uses. These expanded porphyrin-like macrocycles are efficient chelators of divalent and trivalent metal ions. Metal complexes of these compounds are active as photosensitizers for the generation of singlet oxygen and thus potentially for inactivation or destruction of human immunodeficiency virus (HIV-1), mononuclear or other cells infected with such virus and tumor cells as well. A variety of texaphyrin derivatives have been produced and many more are readily obtainable. Various metal (e.g., transition, main group, and lanthanide) complexes with the texaphyrin and texaphyrin derivatives of the present invention have unusual water solubility and stability which render them particularly useful. These metallotexaphyrin complexes have optical properties making them unique as compared to existing porphyrin-like or other macrocycles. For example, they absorb light strongly in a physiologically important region (i.e. 690-880 nm). These complexes also form long-lived triplet states in high yield and act as efficient photosensitizers for the formation of singlet oxygen. These properties, coupled with their high chemical stability and appreciable solubility in polar media such as water, add to their usefulness.

Abstract: Blood bag system for separating whole blood into upper, middle, and lower components which can then be isolated from each other in an automated manner. The system comprises a primary or main blood bag (3) having first and second outlet ports. The first outlet port communicates via tubing with a first satellite bag (21). The second outlet port communicates via tubing with a second satellite bag (35) at one end and at the other end communicates with a tubular member (17) extending into and toward the bottom of the main bag (3). In use whole blood is drawn into the main bag (3) through an inlet port and centrifuged to form an upper, less dense plasma portion (9), a lower, more dense red blood cell (11) (RBC) portion and an intermediate portion of buffy coat (13) (including platelets). Pressure is then applied to the bag (3) with the first outlet open and the second outlet closed to express all of the upper plasma (4) through the first outlet port after which the first outlet port is closed and the second outlet is opened. The lower RBCs (11) are expressed by pressure through the tubular member and second outlet, leaving only the intermediate buffy coat (13) in the main bag (3). The system may be automated with sensors to monitor and control the flow of fluids through each outlet and from the main bag (3).

Abstract: In the manufacture of a multi-coloured skin by the powder slush moulding process, one-piece slush skins (24, 26) are respectively formed in successive process steps, the said skins extending over the entire mould (10), which is divided into individual colour zones (14, 16) by means of dividers (18). Once the first slush skin of the first colour has been manufactured, the area assigned to a different colour is separated off and partially demoulded, the other part of the slush skin remaining behind in the mould. After that, a complete second slush skin is formed both in the previously demoulded subarea and in the area of the first slush skin remaining behind, and so on. Viewed from the textured side, a multi-coloured slush skin (32), which is distinguished by an exact and visually clear parting line (34) between the individual colour areas, is then obtained after final demoulding.
