Title: Process for the production of reactive calcium hydroxides for purification of gas and exhaust gas
Inventor: SUCHENWIRTH HERMANN DIPL CHEM
IPC: B01D53/64
Filed: 1988-05-10
Abstract: In the production of Ca(OH)2 from burnt lime (CaO) by slaking, to improve the properties of calcium hydroxide, salts, inter alia, are added to the slaking water. Chlorides and nitrates accelerate the slaking process, for example, sulphates, hydroxides, phosphates and carbonates prolong it. According to the invention, to prevent excessively short and excessively long slaking times, accelerating and prolonging salts are used in combination. For example, the accelerating action of iron(III) chloride can be removed again with iron(III) sulphate.

Abstract: For cultivations of row crops, tractor-drawn seed drills having a plurality of discharge members arranged transversely to the direction of travel at the spacing of the rows are used, the tractor track serving as a travelling corridor for subsequent cultivation operations, such as fertilisation. An apparatus for the distribution of fertiliser in such a cultivation of row crops consists of a tractor and of a spreader received or drawn by the latter and having a fertiliser container and a plurality of spreading members which are arranged transversely to the direction of travel at an approximately equal spacing and which spread out between the plant rows the fertiliser fed to them from the container in a respective metered quantity. In order to use the travelling corridors made available by the sowing for fertilisation and to allow satisfactory subsequent travelling during fertilisation, with n discharge members on the seed drill the spreader has (a . n + 1) spreading members, a being a whole number. Furthermore, a fertiliser quantity m is fed to the two outermost spreading members and the fertiliser quantity 2m is fed to all the spreading members located between them.

Title: Motor-driven indoor model aircraft
Inventor: BAUER REINHARD
IPC: A63H27/04
Filed: 1988-07-07
Abstract: The invention relates to a motor-driven indoor model aircraft. At the free end of a rod, which is mounted to pivot about a horizontal axis, a floating axle is provided which extends transversely to the rod. Suspended in an oscillating manner on the floating axle is an air screw with a drive motor, the axis of rotation of the air screw intersecting the floating axle perpendicularly. In order to prevent uncontrolled tilting of the model aircraft, the weight of the drive motor acting below the floating axle is greater than the lift of the air screw. An additional compensating torque, engaging on the rod and at least partially compensating the torque because of the weight, permits lift-off of the model aircraft.

Title: Load selector for varying the transformation ratio of three-phase transformers having windings connected in delta
Inventor: WIDMANN WERNER
IPC: H01H9/00
Filed: 1988-09-28
Abstract: In the case of such load selectors, the stationary selector contacts (8) of each of the three phases normally lie in in each case one plane (1, 2, 3), (located at right angles to the apparatus axis), distributed over the circumference of an insulating cylinder (6), and a preselector having stationary preselector contacts (8.1) is provided on planes (4, 5, 4') (which likewise lie at right angles to the apparatus axis) in order to enlarge the range of variation which can be set. According to the invention, a further chamber (18) for accommodating the preselector contacts (8.1) is provided coaxially underneath a chamber (17) for the selector contacts (8) on the insulating cylinder (6) whose diameter is the same over its entire length, and mutually corresponding preselector contacts (8.1) of the three phases in each case lie on a plane (10) (which intersects the apparatus axis at an acute angle) on an ellipse and at the same time form the corners of an approximately equilateral triangle. Advantageous solutions result especially in the case of an arrangement of the preselector contacts (8.1) of in each case at least one phase at an apex of this ellipse. A structure of load selectors according to the invention also makes it possible (if the cylinder diameters are relatively small) to provide a sufficiently large distance between the preselector contacts (8.1) to be insulated from one another, for rated voltages up to at least 400 kV, and said structure is thus particularly suitable for load selectors for high output voltages. <IMAGE>
