Title: Cleaning poultry feathers with chlorinated hydrocarbons - with reduced cost and without polluting environment with waste water
Inventor: KRUCHEN ERNST
IPC: B68G3/10
Filed: 1976-03-25
Abstract: Cleaning of poultry feathers is carried out by washing them with an organic cleaning liquid consisting mainly of chlorinated hydrocarbons to which may be added bleaching or brightening agents or dyes, pref. at 60 degrees C. The cleaning liquid is circulated in a closed circuit. The feathers are then dried at =130 degrees C in >=1 drying chamber of which the vol. comprises 3-10 times that of the washing chambers. The mass of feathers to be cleaned may comprise only 5-20% of the nominal capacity of the washing chamber. The cleaning liquid used is pref. a C2 hydrocarbon derivative. The process may be applied to poultry wings, which are cleaned and then completely or partially coated with a synthetic material to provide permanent elasticity or to take an electrostatic charge which provides the feathers with a therapeutic effect for persons suffering from rheumatism.

Title: Coupling for cold formed pipe ends - has flange around pipe end hardened and drilled for passage of pin
IPC: E04G7/30
Filed: 1976-12-01
Abstract: The end of a metal pipe (1) is reduced in dia by cold forming till it has an outside dia, which is only slightly less than the inside dia. of the pipe to which it is to be connected. A mandrel is placed inside the pipe during cold forming. The end of the tube is at the same time given a chamber (11), so that it can be fed easily into the tube to be connected. As the material in the shoulder (19) between the two pipe sections is compressed, the hardness is increased. This can otherwise only be achieved by a hardening process. Holes are provided in the reduced section and are used for a pin which is passed through the pipe ends which are to be connected to lock them together.

Title: Use of waste heat from power station boilers for drying gypsum - saving energy input and cooling water
Inventor: HOELTER HEINZ
IPC: C01F11/46
Filed: 1977-06-18
Abstract: Gypsum is converted hemihydrate using the exhaust gases from coal fired power stations. Dust is removed from the gas stream by a filter. The gas is then passed to a drying system into which the gypsum dihydrate is fed and changed to the hemihydrate. The pref. drying system is a fluidised bed. The exhaust gases are cooled at the same time. SO2 is removed from the cooled gases by scrubbing and converted to gypsum. There is a saving in additional energy for the drying process and less water is required for the gas scrubber.

Title: Nuclear fusion using synthetic plasma beams - which circulate, in opposition, around reaction chamber after plasma enters chamber
Inventor: NOWAK KARL ING
IPC: H05H1/10
Filed: 1977-12-12
Abstract: Controlled nuclear fusion, as in parent patent, is by means of synthetic plasma, using a closed annular reaction chamber, in which the two plasma beams can circulate in opposite directions. Teh chamber is maintained at a high vacuum. In the addition, while the plasma beams are being projected intot he chamber, a portion of the contracting magnetic field coils of the reaction chamber co-operates with contraction coils of the firing path for the plasma. After the plasma has been injected into the chamber, the contracting magnetic field coils are closed by a further coil completing the circuit around the chamber, so that the plasma beams continue to circulate in opposite directions along an annular path. By using an annular path with the beams continuously circulating in opposite directions, a more compact construction is obtd. c.f. a previous reaction chamber of 3-30m. length.
