Abstract: A turbine includes a rotor having at least two rotor members for rotating in a plane, the rotor members being substantially diametrically arranged and attached to an axis situated substantially transversely to the plane, and drive unit coupled to the axis, wherein the rotor members include a fluid contact member, that is hingingly connected to an arm which is attached to the axis, characterized in that the fluid contact members are adapted to hinge between a fluid-active position in which the members project transversely to the plane and a fluid-transparent position in which the members extend mainly parallel to the plane.

Abstract: A traffic device (1), such as roadside post, provided with an indication element (3) having a visible area (2) and with a cleaning device (4) for cleaning the indication element (3), in which the cleaning device (4) comprises a plurality of cleaning elements (5), in which each cleaning element (5) comprises an elongate and flexible body (6) which, at one end, is attached to the traffic device (1) and from there extends in an unsupported manner and in which the body (6) of the cleaning elements (5) in each case extends along the visible area (2) in such a manner that the body (6) can swish across the visible area (2) with its length in order to clean it.

Abstract: An installation for increasing the daylight yield in a stadium provided with a playing surface, stands, and optionally a covering, includes an essentially vertical light-reflecting body to guide the light incident on the body towards the playing surface in the stadium. Preferably the reflecting body is arranged along the free peripheral edge of the covering of the stadium. In one embodiment the reflecting body includes a multi-layer construction of two corrugated sheets with a light-reflecting foil between them. The installation can increase the light yield in a covered stadium by between 30% and 50%.

Abstract: Asthma is one of the most common chronic diseases (155 million people worldwide) and is rapidly increasing (20-50% per decade), particularly in children (currently 10% in The Netherlands). Asthma impairs the quality of life and is a major cause of absence from school and work. Asthma, if not treated properly, can be life threatening. The invention provides a nucleic acid library comprising genes or functional fragments thereof wherein the genes are essentially capable of initiation and/or progression and/or suppression and/or repression of an immune response.

Abstract: Polyfluorocarbon resin particles and metals are codeposition from electroplating baths to form coating layers of a very homogeneous structure, when said positively charged resin particles having a particle size of less than about 10 .mu.m are kept dispersed in said baths in the presence of both a cationic and a nonionic fluorocarbon surfactant in a molar ratio between 25:1 and 1:3.5 and in a total amount of at least 3 .times. 10.sup.-3 millimoles per m2 of surface area of said particles.

Abstract: A method of thermally treating glass products in which the products are conveyed through a number of heating zones and/or cooling zones of a tunnel furnace and are heated and cooled, respectively, by means of an airflow maintained in each zone in a direction transverse to the direction of transport; according the invention, the velocity of the airflow increases gradually both in the heating zones and in the cooling zones; for that purpose, two perforated partitions having gradually increasing flow apertures for the airflow are provided in each zone.

Abstract: Supporting means for a color selection electrode of a color cathode ray tube comprising metal pins sealed in the wall of the tube, and resilient clamping members secured to the electrodes and bearing upon pairs of the pins.

Abstract: Method of sealing glass objects to one another by means of comparatively low voltages, in which method the preheated seal joint is heated by passing current through it by means of a large number of electrodes which are in mechanical contact with the glass and belong to at least two current circuits which are periodically switched on and off and each comprise at least two series-connected current sources.
