Patent DE-2819346-A1 (DE)
Title: Boiling reactor with moisture separators in annular array - around central space for passage of vertical control rods
Inventor: LINDNER JOHANN
IPC: F22B37/30
Filed: 1978-05-03
Abstract: A boiling reactor comprises a reactor pressure vessel with a removable top closure. Steam-water mixture leaving the core passes through a number of moisture separators before leaving the pressure vessel. Each moisture separator is of box-like shape contg. packages of vertical plates between which the steam flows. These moisture separators are arranged in an annulus adjacent the inner wall of the vessel. The steam-water mixt. flows downwards through them and the steam leaving the separators at the bottom passes into an annular duct defined by the wall of the vessel, the bottom of the steam separators and a circular plate, typically of conical form, which is connected to the steam separators and leads to the vessel wall. all the control rods coupled to control rod fingers in the core pass up through the central region of the vessel inside this conical plate to control rod drive mechanisms mounted above the top closure of the vessel. The steam from the annular duct leaves the vessel through a number of radial outlets around its periphery. The control rod drive shafts do not need to pass through the steam separators and thus considerable sealing problems are eliminated.

Title: Hair-like plastic thread for implantation - has several filaments and anchoring loop through which skin tissue grows
Inventor: MILLER PAUL W
IPC: A61F2/10
Filed: 1979-03-27
Abstract: An open loop forms an anchoring section of a thread resembling natural hair. From the anchoring loop, elongated filaments extend, and these stand out from the surface of the skin, when the loop is implanted. The skin tissue grow through the loop so that at each implantation point, the filaments attached to the loop and to the skin are held securely. The hairlike thread is natural or synthetic but is pref. polyester or polyamide, and the loop is formed by an adhesive. The thread can be pulled out after breaking the bridge of the loop. The loop may form an integral part of the thread with its branches, and the secure holding which results, positively separates the outer from the inner section of the thread. If the implanted hair is dyed, subcutaneous penetration of the dyestuff is prevented.

Title: Continuous washing machine for batches of linen - retains batch by scoop-like surface permitting prefabrication before assembly
Inventor: STEINORT HANS
IPC: D06F31/00
Filed: 1979-03-28
Abstract: Surface winding spirally over 180 degrees, forms a transport channel through each separate compartment of the rotary, reversible drum in a continuous washing machine for linen in batches, which, rotated in one direction washes within a chamber, and rotated in the reverse direction moves the batch of linen from chamber to chamber. A guiding surface divides each outlet through a partition into an inlet side of the drum mantle and an outlet side away from the drum mantle. The winding surface starts at the one partition between guiding surface and inlet side and extends to the opposing partition between guiding surface and outlet side. In the zone of the common outer mantle of the drum and the transport channel, from a winding point where four part-surfaces meet to form the spiral surface, it is inclined towards and blends into the partition. The drum is designed so that the chambers can be prefabricated for subsequent assembly, without detracting from the washing effect or from the throughput.
