Abstract: A cryo-cell assembly for biological material including a space for receiving the material, the space being at least partly enclosed by means suitable for conducting heat from the space to a heat sink and including heat generating means in heat conducting relationship with the space. Power is applied to the heat generating means according to a desired temperature cycle stored in memory. The power supply unit senses actual temperature in said space and compares this with the desired temperature. Power is supplied to the heat generating means whenever the actual temperature falls below the desired temperature.

Abstract: In a process for de-inking or removing printing ink from waste paper, the prepared suspension of fibres is initially given flotation treatment for a short period, i.e. for example for two minutes, in a single-stage flotation unit (2) and then subjected to washing in one or more washing stages (7) in such a way that a hydrocyclone (classifier) (6) can be connected in-line between the two cleaning stages. The rejects from all stages are led without intermediate cleaning to a common internal waste water cleaning unit (clarifier) (4), which separates the rejects into thick sludge, thick sludge filtrate and clarified water. The clarified water and also, if desired, the filtrate from the sludge press are used again in the system as process water. The process is particularly suitable for the removal of electro-static inks (laser inks), which are difficult to remove and permits the production in a simple way of a paper of particularly good cleanliness from waste paper, accompanied by the most sparing consumption of water. <IMAGE>

Abstract: A process for the catalytic treatment of a polysilazane containing an average of at least two, preferably at least three,  3BOND SiH groups per molecule with a catalytically effective quantity of a strong inorganic or organic acid catalyst. The other organic radicals in the polysilazane that are bonded to the silicon or nitrogen atoms are hydrocarbon radicals free from alkene or alkyne unsaturations. The polysilazanes treated in this manner can be characterized by good thermal behavior and can be used, in particular, as precursors of ceramic products with a high yield of inorganic products.

Abstract: Chlorine dioxide is increasibly used to bleach pulp and the like. Chlorine dioxide is produced in a reactor, which contains a plurality of superimposed bubble cap trays, which are provided with passages for the gas and with duct, which is independent of the gas passages and serves as an overflow for the liquid. In order to maintain a maximum ClO3/acid ratio for the longest time possible, the reaction chamber above each bubble cap tray is divided into a large number of reaction compartments by vertical partitions, which define openings for the passage of the reaction liquid. Acid can be supplied to each compartment. The partitions can be used to define in each reaction chamber any desired number of reaction compartments, which are connected in parallel for the flow of acid and are connected in series for the flow of the chlorate solution.

Abstract: The invention relates to a sailboat in which the hull is defined by cross-sections forming equilateral triangles standing on one tip with convex sides and which continuously decrease in size toward the bow and stern so that the keel line and the side edges coincide there and a substantially symmetrical ellipsoid is formed. The ellipsoid includes an extended bow cockpit and downwardly and outwardly slanting adjustable rudder vanes simultaneously forming rest feet. A central seat in the hull receives an adjustable mast of a profiled sail corresponding to a symmetrical airfoil profile having an adjustable airfoil cap at its front end. Several beams at the mast can be pulled up over each other and sail segments mounted in between can be reefed.

Abstract: In order that holes may be produced in a simple and safe manner in a plaster plate (1) to be used as sound adjuster in a room, holes (15) are punched out of the plate, e.g. in the shape of slits, by means of a cutting tool. Hereby the considerable dust and noise inconveniences caused by the hitherto known machining are avoided. By slits (15) that must lie close to each other, it is possible to punch in two stages, i.e. first with double distance and then in the space between. This prevents fracture of the plaster and tearing of any paper that may be on the surface. The cutting tool is provided with punches (7, 8), in a shape corresponding to the holes. Each punch is provided with an inclined blade (10) which forms an angle of the horizontal of 13 DEG . The cross sectional shape of the blade is V-shaped, with two blades (11) running along the sides of the punch. In this manner the material (9) is punched out in a gentle and even manner, whereby is obtained a perfect hole free from burrs and fractures of the plaster in the edge area.
