Title: Zirconium alloy for use in boiling water nuclear reactors - subjected to soln. and ageing heat treatments to improve corrosion resistance
Inventor: URQUHART ANDREW WILLART
IPC: C22F1/00
Filed: 1976-11-13
Abstract: Zirconium alloy component contg. Sn, fe, Cr, and particles of an intermetallic phase, has improved resistance to accelerated pustular or bubble corrosion in boiling water nuclear reactors. The novelty is that the component microstructure has a segregation of particles with dia. 100-400 angstroms in two-dimensional rows along the grain- and subgrain-boundaries, and distributed throughout the entire component. The alloy pref. contains (a) no Ni, 1.5% Sn, 0.2% Fe, 0.1% Cr, 0.1% O2, rest Zr; or (b) 1.5% Sn, 0.15% Fe, 0.1% Cr, 0.05% Ni, 0.1% O2, rest Zr; and is esp. used for fuel cans or channels contg. a bundle of fuel cans. The component is pref. heated to convert the alpha-phase into the beta-phase and dissolve all intermetallic particles, then quenched to room temp. to avoid pptn. of intermetallic particles; reheating is used to obtain the particles of 100-400 angstroms dia. round the grain boundaries. An esp. pref. treatment is heating 3-60 seconds at 1000-1100 degrees C., water quenching at >800 degrees C/second, then reheating 2-4 hours at 400-600 degrees C. The working life of the components is at least doubled due to the reduced corrosion.

Title: Wind operated power generator - has vertical shaft with several rings of pivoted and counterbalanced blades rotating in horizontal planes
Inventor: LANDSIEDEL EDMUND
IPC: F03D3/06
Filed: 1977-04-28
Abstract: The turbine has a vertical shaft on which several rings of blades are assembled one above the other. Each ring contains six blades equally spaced round the ring. Each blade is carried at the end of an arm projecting radially from the shaft. The blade can swing about the arm and is counterbalanced by a weight which swings about the radial arm in a vertical plane. The mechanism brings the blade down to catch the force of the wind and swings it to a horizontal position on the return part of its motion so that it offers no resistance to the wind. The vertical assembly of several rings enables the full power of the wind to be caught.

Title: Screening arrangement against disturbing incident light - has solid elements surface coated for partial light absorption and reflection
Inventor: HANSTEIN FRIEDRICH
IPC: F21V11/00
Filed: 1977-05-18
Abstract: The light screening arrangement is used to screen a given space against disturbing incident light, consists of combined transparent solid individual elements and it can be used in the design of light exposure meters or equipping headlights. It ensures that light is not radiated to a human eye. The transparent solid individual elements are surface treated and joined so that their composite surfaces partly absorb light and partly reflect it. These surfaces are arranged at ninety degree to the plane of the maximum surface expanse of the arrangement, at such intervals that they form a geometrical grid. The absorbing effect is obtained by surface coating. This arrangement can be fitted in front of a motor vehicle headlight unit by a swivelling arrangement.

Title: Sausage suspension loops - for mechanised feed to clip closure machine in continuous twin strand with buttonhole stitches
Inventor: MUENZ HANS
IPC: A22C15/00
Filed: 1977-05-28
Abstract: The cord loops with a knot for suspending sausages are normally fed by hand into the machine to close the ends by a clip which also fixes the loop at the knotted end. This labour can be saved by feeding to the machine a continuous strand. The strand consists of two cords side-by-side which have pairs of buttonhole-stitches ot join them at distances corresp. to the length of the loop. On entering the machine, a loop is cut to length by a cutting between the stitches. The thickened end, caused by the button hole stitch, prevents the loop from slipping out of the clip.

Title: Washing machine fluid level control - uses a computer with stored filling times according to wash programs
Inventor: BREITBACH HEINER
IPC: D06F39/08
Filed: 1978-04-25
Abstract: In the water level control system for a washing machine, the intervals between the minimum level and further filling levels are registered as filling times. These time scales are stored in a computer to develop washing programs for the washing machine. The process gives a simple method of controlling the water level in the washing machine, according to a variety of programs, without requiring further control units. As the washing machine is being filled with water, the filling times are monitored and controlled by the computer unit, according to the standard filling time for the washing program in force. This allows fluid flow control and fluid level corrections against the min. level standard.

Title: Storage system for solar energy - consists of storage body with two flow passages in contact, one connected to solar heat source the other to the user
Inventor: HANSEN UWE
IPC: F28D20/00
Filed: 1978-06-30
Abstract: Heat from a heat source is led into a heat storage vessel using a heat transfer medium. Flowing countercurrent to this stream is a second heat transfer medium connected to the user. If the supply of heat balances the rate of use, no heat is accumulated in the store. If the supply exceeds the use, then heat begins to be stored. Similarly if the supply is less than the rate of use, heat is removed from the store. Used with solar energy systems. Arrangement allows energy to be stored or released irrespective of whether the sum is stirring or not.
