Title: Arrangement for inspecting the bottom of the reactor vessel of a boiling-water reactor
IPC: G21C17/08
Filed: 1984-09-17
Abstract: The novel development relates to an arrangement for inspecting the bottom of the reactor pressure vessel of a boiling-water reactor. Since this area is radioactive and therefore cannot be used directly, an arrangement which does not require the removal of essential parts of the reactor core for the inspection is expedient. Allowance is made for this by an arrangement which has a guide tube (10) which extends over the bottom (20) and is for a flexible tube (12) which protrudes out of the mouth and encloses a flexible shaft (16) for turning and swivelling an underwater camera (13) arranged at the end. For this purpose, the flexible tube (12) can be adjusted in its position from outside by a shaft (17) or a hauling cable, so that the entire bottom region above the lower crown of a reactor pressure vessel can be inspected without requiring the removal of all the fuel rods and control tubes. <IMAGE>

Title: Device for producing prefabricated building units from concrete
Inventor: MATHIS HUGO
IPC: E04G7/16
Filed: 1984-11-09
Abstract: In order to avoid lateral buckling of the load-bearing column 7 of a vertically adjustable working platform 2 for producing peripherally-closed prefabricated building units 1, said load-bearing column 7 is supported with respect to the prefabricated building unit 1 by means of struts 9, the latter being fastened on the load-bearing column 7. In order that these struts 9 do not in each case have to be cut exactly to the length of the distance between the prefabricated building unit 1 and the load-bearing column 7, rather that struts 9 which are longer than the above-mentioned distance can also be used, a bushing 8 is fastened on the load-bearing column 7. Said bushing comprises two cylinder shells 10, 11 which can be clamped together and are connected by a hinge 12. On its outer side, each cylinder shell 10 and 11 bears, via a simple cardan joint, a pipe clamp 14 of a conventional type, and the struts 9 are clamped in said pipe clamps. These struts 9 can project beyond these pipe clamps 14 in an unobstructed manner. <IMAGE>

Title: Arrangement for the electrical connection of low-voltage lamps or lights, especially halogen lamps
Inventor: LEUCHTMANN GUENTER
IPC: F21V21/096
Filed: 1984-12-18
Abstract: The arrangement for the electrical connection of low-voltage lamps or lights 10 to corresponding low-voltage supply leads 4, 5 makes use of a permanent magnet 13a, 13b in order to provide a force-fitting mounting or suspension of the lamp or light on the supply leads 4, 5 (which consist of material which can be magnetised) and at the same time ensure production of the electrical connection. The permanent magnets can either themselves be electrically conductive or they can consist of electrically non-conductive material, so that one conductor part must then be connected to the permanent magnet. Two electrically conductive permanent magnets, which are electrically insulated from one another, or two conductor parts and an electrically non-conductive permanent magnet, which isolates the two conductor parts from one another, can in each case be combined to form a structural unit which can then be adjusted as desired on a corresponding rail which is formed by the low-voltage supply leads. <IMAGE>
