Title: Reactor ceiling brick suspension - by telescopic tie rods resting on compression springs outside
Inventor: WILL RUDOLF
IPC: F27D1/02
Filed: 1979-03-24
Abstract: Three layers of graphite bricks in the reflector ceiling of a nuclear reactor are kept separate by spacers. Retainer bolts are inserted in two of the layers and are threaded to the bottom ends of two telescopic tie rods. The tie rods transmit the load to the thermal shied, through compression springs. Each set of springs has an indicator pin, which will stand out higher above the lid than the other if a fracture has occurred. The movement of the pins can also be used to actuate warning signal contacts. This creates a simple visible indication whether the ceiling or its suspension is sound and which section is defective.

Patent DE-2928893-A1 (DE)
Inventor: GERBERT HEINZ DIPL ING
IPC: F24D3/18
Filed: 1979-07-17
Abstract: In conventional systems, the collector pipes for the heat transfer medium extend underground at a horizontal distance from one another, which is disadvantageous owing to the fact that the pipes have to be laid individually in a labour-intensive and space-consuming manner and to the unacceptably high cost of retrofitting such earth collectors to existing houses. The earth collector according to the invention eliminates these disadvantages in that it is designed to be placed in the ground upright, its pipes (5) extending parallel to one another and being situated one above the other. The earth collector shown in the Figure as an example is preferably designed as a prefabricated grid element and contains return pipes (5b) and flow pipes (5a) which are arranged one above the other, are combined to form groups and which open out into the common deflecting distributing pipe (7) and in groups into the return distributing pipe (9) or the flow distributing pipe (8) respectively. The pipes (5), which are made of flexible plastic, are held by means of spacers (6). The earth collector illustrated is arranged upright in a trench, the latter having a mean width of about 50 cm and the pipes having a diameter of 2 cm. <IMAGE>

Title: Settling tanks for rinsing liq. used on filing machines - which are employed to file graphite electrodes utilised in electroerosion machines
Inventor: HAGEMEIER AUGUST
IPC: B01D21/02
Filed: 1979-10-19
Abstract: After leaving the filing machine, the rinsing liq. contaminated with graphite sludge etc. is fed through a row of settling tanks, each of which is fitted with a weir upstream of an overflow, so the liq. flows in cascade through the tanks. The supernatant liq. in the last settling tank is returned to the filing machine. A row of four settling tanks is pref. used, the first three each contg. a weir made of sheet metal and located next to the overflow. During the filing of the graphite electrodes, the filing zone is flooded with water contg. detergents, corrosion-inhibitors and other substances. This aq. soln. removes the graphite sludge, which is collected in the settling tanks so the soln. can be re-used.

Title: Double toggle lever system for press frames - has intermediate lever hubs with teeth driven by rack or pinion
Inventor: KAENDLER PETER
IPC: B29C45/68
Filed: 1979-12-10

Title: Window turn and tilt mechanism - has blind frame pressure pressing locking pieces against wing frame, for movement
IPC: E05C3/36
Filed: 1980-04-24
Abstract: The conventional handle, normally exerting a pronounced effect on linear guidance, is eliminated, and operation is simplified in a window with turning, or turning and tilting action. The fittings consist of one or more bolting pieces (4a,4b,4c) activated by pressure. These are activated by the pressure of the blind frame (2) to bring them against the wing frame (3), so that pressure on the former permits the latter to tilt or swing upwards. Such a bolting piece is pref. located in the top, and bottom, and opening side. The one at the top can activate the turning lug via one transmission spindle (5a), while the one on the opening side activates the tilting lug via another (5b).
