Title: Introduction of particulate material into a borehole
Inventor: CHAMP JAMIESON E
IPC: E21B33/13
Filed: 1993-06-18
Abstract: Bentonite, and other water-sensitive materials in granulate form, are introduced into boreholes. The material is borne into the borehole through a conduit, in which a flow of air (or nitrogen) not only transports the material but also keeps water that may be present in the borehole from entering the conduit. The materials are contained, above ground, in hoppers arranged to feed in parallel into the conduit. Material from a selected hopper enters via a respective valve into the conduit. The hoppers are pressu-rised to ensure the moving gases in the conduit do not enter the fall pipe. Having turned the air on, the technician lowers the con-duit to the bottom of the borehole; then he opens the valve to admit the selected filler material; then he withdraws the conduit gradually and progressively up the borehole, depositing the material. The conduit is of flexible material, and can be held in the hand, to assist in sensing the flow of material.

Title: Containment systems for insulation, and insulation elements employing such systems
Inventor: SLOAN FRANK P
IPC: B64D13/00
Filed: 1995-06-13
Abstract: Acoustic and thermal insulation for an enclosed space, particulary the passenger cabin of an aircraft, comprises insulating elements lining the interior wall. Each element is enclosed in a bag of thin flexible moisture impervious material and each bag is provided with an aperture at a lowermost point at which moisture condensed from humid air within the bag will pool under gravity. A duct connects each element interior to the exterior of the enclosed space, so that air pressure in the bag can be equalised with that in the space without using air from the enclosed space. Any condensate in the bag can flow to the exterior, and only air from the exterior can enter the bag interior.The elements are formed in appropriate shapes, such as rectangular to fit in the cells formed between the frames and stringers of an aircraft fuselage, or so as to be wrapped around the frames. All of the elements in a column can be connected in series, so that each element in the column comprises part of the flow duct for the element above it. When the enclosed space is subject to a fast reduction in its internal air pressure the resultant air flow out of the bags carries with it any condensed liquid.
