Patent DE-2852019-A1 (DE)
Title: Catalytic recombination of hydrogen and oxygen - from boiling water reactor with recycling of cooled steam to recombination unit
Inventor: VEGEBY ANDERS UNO INGVAR
IPC: C01B5/00
Filed: 1978-12-01
Abstract: A method for the catalytic recombination of radiolytically formed hydrogen and oxygen in the treatment of the condenser gases from a boiling water reactor is carried out as follows: The steam contained in the gases is entirely or partly supplied to a cooler, then after cooling, is recycled to the recombination unit, where it serves as a temp. moderator during the oxidising process. More specifically, a steam ejector pump is used for circulating the steam; this produces a pressure rise to compensate the loss passing through the catalyst bed and the cooler. Used for recombining the oxy-hydrogen gas without risk of explosion. The method avoids the bypassing of the turbine with high pressure steam, as occurred in previous processes, and thus results in improved energy efficiency.

Title: Ozone generation in electric field - from turbulent oxygen-contg. mixt. followed by expansive cooling to stabilise ozone
Inventor: ADAM BRUNO DR
IPC: C01B13/11
Filed: 1978-12-11
Abstract: Ozone is produced by passing an oxygenous gas mixt. through an electric field and by cooling the mixt. in or directly after the electric field by expansion. A turbulent flow is created in the mixt. immediately before entering the electric field. Rapid cooling by expansion results in a stabilisation of the oxone and in a redn. of the recombination reactions of atomic oxygen to O2. The silent gas discharge remains stable and stays in the region which is best for the ozone generation.

Title: Elongated synthetic fluted strip for roof covering - having long edges turned over to form spigot and socket
Inventor: WEINHOLD JOACHIM DIPL ING
IPC: E04D3/40
Filed: 1979-02-09
Abstract: Curved over long edges of a synthetic strip for use in roof covering are arranged at a first height from the sole of the strip at one end. From there the turned over edges extend at the same height over a predetermined distance. From the end of this distance to the other end of the strip, the turned over edges are at a second height which is less than the first height. For pref. the first height is greater than the second height at least by the thickness of the strip, so that one end forms a socket whilst the smaller end forms a spigot. The length of the zone having the first height is about 160 mm. Used to improve the synthetic fluted strips so that they can be laid conveniently, esp. where two strips of synthetic material overlap. The thinner end of one strip can be inserted into the socket of another without any manipulation being necessary on site.
