Title: Water borehole ageing monitoring procedure - monitoring set parameters in static and pumping modes to detect deterioration of borehole apparatus
Inventor: MICHEL SEGUIN
IPC: E21B47/00
Filed: 1992-04-17
Abstract: The procedure, for use on a borehole with a sleeve (5), a strainer (1) in the water-bearing rocks, and a motor/pump unit (6), consists of producing a diagraph in a static mode of the boreholes flow and physical-chemical parameters such as temperature, electrical conductivity, dissolved oxygen content and turbidity, putting the borehole into operation in controlled conditions and monitoring the same parameters, and constructing a new diagraph. The two diagraphs are used to produce a relationship between the depth of the borehole and the measured parameters. The control parameters are measured during pumping, at a fixed flowrate which is close to the operating rate of the borehole, with variations in the parameters indicating borehole ageing, e.g. as a result of corrosion, abnormal circulation, sleeve micro-perforations or a breakdown of cement. ADVANTAGE - More reliable detection of borehole ageing and deterioration.

Title: Box for video cassettes - uses moulded flexible tongues projecting across opening at edge of box to retain cassette.
Inventor: BRUNO MATHIEU
IPC: G11B23/023
Filed: 1992-04-24
Abstract: The video cassette box has a flexible blade (1d) across the opening of the box to temporarily retain the cassette (2) when the box is opened. The box opens so that the cassette can be extracted from the side of the box rather than the face. The flexible blades (1d) that retain the cassette are formed as the box is moulded. The retaining blades normally project across the edge of the cassette, and bend down as the cassette is extracted. The blades are shaped with a dual curvature to give a spring action. ADVANTAGE - Simply manufactured retainers that prevent video cassette falling out of its storage box regardless of position of box when it is first opened.

Title: Position stabiliser, esp. for landmine - comprises flat rigid ring, disc or cross, attached to mine by twisted cables or folded strips which deploy on launching
Inventor: FRANCIS LEDYS
IPC: F42B10/02
Filed: 1992-06-26
Abstract: The stabiliser consists of a flat rigid member (20) with smaller outer dimensions than those of the sub-munition, to which it is connected by semi-rigid suspension elements (211, 212). The suspension elements are folded on launching or scattering and are deployed by aerodynamic effect or the nature of the material from which they are made so that the sub-munition occupies a satisfactory position when on the ground. The suspension elements can be attached to the sub-munition by rivetting, welding or similar, and they can be made from twisted cables of a material such as a polyamide, or from metal or plastic straps which can have thin zones to facilitate folding. The flat member can be made in the form of a thin ring, disc or cross. USE/ADVANTAGE - Sets mine in correct position on deployment. Design is simple and operation is efficient.
