Title: Method and apparatus for acoustically investigating a casing in a borehole penetrating an earth formation
IPC: E21B47/08
Filed: 1980-07-04
Abstract: Methods and apparatus for acoustically investigating a casing 12 in a borehole to derive the quality of a cement bond 32 behind the casing and casing thickness are described. The techniques employ an acoustic pulse source 56, 36 having a frequency spectrum selected to stimulate a selected radial segment of the casing into a thickness resonance. The selected frequency spectrum enhances the reverberations between the inner and outer walls of the casing which traps the thickness reverberations with significant amplitudes for a duration depending upon the amount of acoustic energy leaked into adjacent media. Acoustic returns are formed by the reflections from interfaces between media of different acoustic impedances and acoustic energy leaked into the bore of the casing from the acoustic thickness reverberations stimulated within the casing walls. The acoustic returns are detected to generate a reflection signal which is processed (at 348 to 364) to determine casing thickness or to evaluate (at 21) the cement bond. The acoustic pulse has a frequency spectrum which is particularly effective in discriminating different cement bond conditions caused by small cement separations 30, known as micro-annuli, around the casing. Several signal processing techniques and tools are described to provide accurate and high resolution cement bond evaluation and casing thickness determination by processing a gated portion of the reflection signal representative of the thickness reverberations. <IMAGE>

Patent GB-2085283-A (GB)
Title: Cooking utensils
IPC: A47J36/36
Filed: 1981-09-18
Abstract: A cooking utensil, such as a kettle, a saucepan or a frying pan, comprises a base 12, a surrounding wall 14, upstanding therefrom, and a skirt 16 surrounding said wall and spaced therefrom to form an air space which is closed at the upper end and traps heat against the wall, thus providing more effective applications of the heat supplied. For a cooking utensil which is heated internally, e.g. an electric kettle, the lower end of the skirt is closed. As heat passes outwards through the kettle wall a percentage is trapped in the space between the skirt and the kettle wall and forms a heat barrier which slows heat loss from the water heating in the kettle. In consequence, the water in the kettle will boil more quickly than in a similar kettle without the skirt. <IMAGE>

Title: Precision current-source arrangement
Inventor: VAN DE PLASSCHE RUDY JOHAN
IPC: H03F3/347
Filed: 1983-12-20
Abstract: A current-distribution circuit (1) supplies a plurality of substantially equal currents (i1, i2, i3 and i4) to a permutation circuit (13), which transfers these currents to outputs (18, 19, 20 and 21) in accordance with a cyclic permutation. The currents in these outputs exhibit a ripple caused by the inequality of the currents (i1, i2, i3 and i4). A detection circuit (30) detects the ripple component of the currents (i1, i2, i3 and i4) and applies this ripple component to a associated control circuit of a block of control circuits (50). The relevant control circuit supplies a control current for correcting the relevant current (i1, i2, i3 or i4) in such way that the ripple component is substantially eliminated.
Patent GB-2142596-A (GB)
Title: Stabilizing semi-submersible structures
Inventor: LANGENBERG HANS
IPC: B63B35/44
Filed: 1984-06-14
Abstract: A semi-submersible structure for use in open water comprises a working platform 7; a plurality of columns 5 on which the working platform is mounted and buoyancy generating means for supporting the working platform above the surface of the water. The buoyancy generating means can either comprise the columns themselves or float means disposed, at least in the semi-submersed state of the device under water. Alternatively the buoyancy generating means can comprise a combination of buoyancy generating columns and float means. Stabilising chambers are formed on or attached to either the columns or the float means outside of the central area staked out by the columns. Each stabilising chamber has a vent 3 at its upper end and a remotely controllable device 2 at its lower end, and the stabilising chambers are freely flooded with water in the semi-submersed position of the structure. In this way, in the event of an undesired leakage in the semi-submersible structure leading to a substantial change in the trim angle thereof, one or more of the stabilising chambers surfaces and thereby changes the position of the centre of buoyancy of the structure in the sense of counteracting the change in trim angle resulting from the leakage. <IMAGE>
