Abstract: A cartridge casing comprises a casing tube having a first end and a head cap. The first end of the casing tube abuts and is joined with the head cap such that an orifice in the first end of the casing tube is aligned with a passage in the head cap to define a flash passage. The head cap and casing tube are held together by a deformable member.

Abstract: A cartridge casing comprising a casing tube formed substantially of metal with a closed end and an open end. The casing tube bounds at least part of a head cap entered into the open end of the tube. The head cap is fixed relative to the tube. An end wall defines the closed end opposite the head cap end of the cartridge. The end wall comprises a weakened region.

Abstract: Systems and methods of performing a seismic survey are provided. The system includes a seismic data acquisition unit having a transmitter window disposed in a first aperture of a lid, and having a receiver window disposed in a second aperture of the lid. A first gasket is positioned between the transmitter window and the first aperture to provide a clearance greater than a threshold to allow the transmitter window to deform. A second gasket is positioned between the receiver window and the second aperture to provide a clearance greater than the threshold to allow the receiver window to deform. At least one of the transmitter window and the receiver window of the seismic data acquisition unit are configured to pass at least one of optical and electromagnetic communications to or from an extraction vehicle via at least one of a transmitter window and a receiver window of the extraction vehicle.

Abstract: The invention relates to a conductive connection assembly (5), a method for manufacturing the same and a kit for a body (23) comprising carbon fibre-reinforced material, e.g. for a vehicle comprising a carbon fibre-reinforced body (23), with an electrical structural network for conducting electric discharges. The conductive connection assembly (5) includes a conductive interconnection element (1) with a conductive braid material (B). Furthermore, a kit is provided, the kit including at least two conductive connection assemblies (5) that are provided with differently shaped interconnection elements (1). Finally, a method that comprises the step of reshaping longitudinal ends (3, 4) of a braid material (B) is provided according to the invention.

Abstract: An pneumatic insulating device (20) is disclosed comprising: a load bearing body, top (24) and bottom parts connected to the load bearing body; and a coiled, insulating pneumatic line (14, 14?) connect to and passing though the top and bottom parts, characterised by both the top and the bottom parts have fixing means (21) for fixing the device between external fixtures.

Abstract: The invention relates to a conductive connection assembly (5), a method for manufacturing the same and a kit for a body (23) comprising carbon fibre-reinforced material, e.g. for a vehicle comprising a carbon fibre-reinforced body (23), with an electrical structural network for conducting electric discharges. In order to improve durability of the body (23) with the electrical structural network, the invention provides that the conductive connection assembly (5) comprises a conductive interconnection element (1) with a conductive braid material (B). Furthermore, in order to simplify installing the electrical structural network to the body (23), a kit is provided, the kit comprising at least two conductive connection assemblies (5) that are provided with differently shaped interconnection elements (1). Finally, a method that comprises the step of reshaping longitudinal ends (3, 4) of a braid material (B) is provided according to the invention.

Abstract: A connecting arrangement for connecting supply lines across a gap between railway vehicles is disclosed. The connecting arrangement electrically and pneumatically connects railway vehicles or pantographs of a train. The connecting arrangement may include at least one flexible electrical power line and at least one flexible fluid line. The at least one power line and the at least one fluid line may be preassembled to form an integral unitary structure.
