Patent FR-2431004-A1 (FR)
Title: Geothermal exchanger taking heat from ground air-conditioning - is installed by simultaneous drilling and casing of hole, partic. useful in loose ground
IPC: E02D7/28
Filed: 1978-07-12
Abstract: Geothermal exchanger constituting a source of heat of an air-conductioning installation is placed in the ground by simultaneously effecting the drilling and casting of a hole directly by the outer tube of the exchanger. The casing is effected by the advancing of the penetration tool so that the exchanger is in place in the ground when the drilling is finished.

Title: Tool for assembling extensible bellows of any length - using lapped crest joints for maximum extensibility
IPC: B29C65/18
Filed: 1979-04-10
Abstract: Extensible bellows are made from annular pieces of metal or plastics sheet or foil by prefabricating pairs of hoops joined at their outer rims, then assembling such single-bellows units by joining their inner rims. A two-part press tool with lips to support the bellows rims is used to consolidate the joints of bellows assemblies by fusion welding or adhesive bonding. For porous bellows, the joints may be discontinuous. The press tool may be fitted with alignment pads and/or a trimming knife. For making bellows of any required length, e.g. for covers for pistons or for lead screws etc. on tensile testing machines. The structure is less stiff and provides a higher ratio of extended to collapsed length than bellows made in one piece with radiused undulating inner and/or outer bellows crests.

Title: Water-ram actuated unit toilet flush unit - uses double slide distributor and slide over waste outlet with pressure cycle derived from nozzles (BR 2.12.80)
IPC: E03D5/012
Filed: 1979-04-27
Abstract: Water rams drive a slide valve distributor and an outfall slide valve, and ball valved nozzle chambers furnish drive pressures once the process is initiated. Depression of a push button effects the descent of a double slide valve distributor causing the water to flow into the pan through a nozzle chamber. At a given water level a float seals the chamber, the pressure rises and the primary slide valve ascends. The waste pipe is uncovered and flows are redirected to fill a reservoir. The ascent of the secondary slide valve closes the outlet and the reservoir contents is released immediately to the pand and the seal is re-established.

Title: Incendiary body, especially shell, missile or bomb, comprising an incendiary case-shot charge
Inventor: CO SOCIETE DITE BUCK CHEMISCH-
IPC: C06B33/00
Filed: 1979-05-16
Abstract: This device is composed of a casing 5, 7, 9 with a steel inner tube 11, an incendiary charge 13 located between the tube 11 and the casing tube 9 and of a splinter charge 19 in the tube 11. The incendiary charge 3 is formed from fragments of metal 23 having a high melting point, which are embedded in a metallothermal heating composition 25 which is ignited by at least one ignition mechanism 27. The mechanism 21 for delayed ignition of the splinter charge 19 is produced in such a way that this charge is ignited only after the end of the reaction of the heating composition 25, the tube 11 being produced in such a way that there cannot take place, at the very least until the end of the reaction of the composition 25, a transmission of heat from the chamber 13 to the explosive chamber 17 which is capable of causing a premature ignition of the splinter charge 19.

Title: Transferring water-cooled reactor fuel elements to storage pool - via hot cell to avoid external contamination of transport container
IPC: G21C19/32
Filed: 1979-09-10
Abstract: Used fuel elements are handled from water-cooled reactors by transferring the elements from a transport container into a water-filled cooling pool. The container is sealed with its opening to a hot cell for dry handling of the elements, the elements are transferred to the hot cell and are then moved from the cell into the storage pool, with controlled cooling during the transfer from the cell to the pool. Pref. suctional capture is used to keep the water away from the hot cell. A control quantity of water is pref. used for cooling. Used for handling of used fuel elements from water-cooled reactor. The method eliminates the need to submerge the handling container in the pool, with the consequent decontamination of its external surface.

Title: Heat exchanger for regenerated gas turbine systems - has bellows forming blind passages balancing out loads on core (NL 29.4.80)
IPC: F28D9/00
Filed: 1979-10-25
Abstract: A large number of compressed air flow channels extend in intimate proximity along selected parts of the head pipes of a heat exchanger of the plate-rib type, so as to lead the heat exchanging medium around selected zones of the circumference of the exchanger. Arrangements are provided to join the flow passages between the inlet and outlet header pipes, in heat exchanging contact with hot gas flow channels in the heat exchanger, as well as to connect the air flow channels with the interior of the header pipes at selected points around the circumference of the header pipers, so that part of the compressed air fed through into them passes through the flow channels. Used for high performance plate regenerators of great weight as used e.g. in gas turbine compressor systems for gas pipelines. The heat exchanging arrangement is designed so that the high mechanical and thermal loadings occurring during operation are diminished, to allow the heat exchanger core to absorb these loadings and avoid high degrees of stress. An optimal rigidity of the arrangement accompanied by great flexibility is thus achieved. Heat exchangers of this type are used in regenerated turbine systems in the range of 5,000 to 100,000 H.P. The exhaust gases have a temp. is approx. 590 degrees C and heat the compressed air to 480 degrees C. The regenerator runs for 120,000 hrs. and 5,000 cycles without planned overhaul and has a life of 15 to 20 years of normal operation.
