Title: Frequency-scan microwave antenna
Inventor: EVANS DAVID HILLARY
IPC: H01Q21/06
Filed: 1991-02-13
Abstract: A frequency-scan microwave antenna, e.g. for an electronically-steerable phased array in a radar, comprises an array of antenna elements (1) and a feed connection comprising dispersive elements (20) forming a delay line (2) between adjacent antenna elements (1). In accordance with the invention each delay-line (2) comprises at least two dispersive elements (20) which are coupled together along at least a part of their length so as to provide a phase (a) versus frequency (fo +/-  DELTA f) characteristic whose gradient is increased by the presence of the coupling (compare (20) with 2a in Figure 7 for the same physical length of uncoupled line 2). This parallel-coupled arrangement of dispersive elements (20) permits a desirably long electric delay to be obtained in a compact structure with acceptable signal losses. The parallel-coupled elements (20) may be formed in microstrip technology. High coupling can be obtained using a Lange coupler configuration, closely spaced lines (20), a local dielectric overlay spanning adjacent lines (20) or overlapping lines (20) may even be used. <IMAGE>

Title: Method of determining compressibility of an offshore reservoir bed
Inventor: DEAN GRAHAM ANDREW
IPC: E02D1/02
Filed: 1991-08-23
Abstract: A method of determining compressibility of an offshore reservoir bed comprises measuring pressure (Pz) within the reservoir and pressure (Pp) at the seabed above the reservoir at a sufficiently high frequency to detect cyclic change due to tidal effect. The reservoir and seabed pressure measurement values are correlated to allow derivation of a tidal effect ratio (dPp/dPz). This is used together with data specific to the reservoir, such as compressibility of the reservoir fluid and porosity of the reservoir solid material, to obtain a value for compressibility of the reservoir bed. The compressibility is used to calculate oil flow and predict possible subsidence of offshore platforms. <IMAGE>

Patent GB-920367-A (GB)
Abstract: 920,367. Geophysical prospecting. JERSEY PRODUCTION RESEARCH CO. Nov. 18, 1960 [Nov. 25, 1959], No. 39699/60. Class 40 (7). [Also in Group XXIV] A device comprises a plurality of pairs of rotatable eccentric weights, each weight of each pair being rotatable about parallel axes which are rigidly connected to a base member, the eccentric weights of each pair rotating in counter directions, and each pair of eccentric weights rotating at different pre-selected rotational speed from that of any other pair. The device is used to create seismic impulses A, Fig. 5, in the earth in a system of geophysical prospecting, Fig. 6 (not shown). By selection of eccentricities, weights and speeds, the wave shape of the seismic impulse may be controlled. In one embodiment a motor 22, Fig. 1, drives gears 24a ... 24u of linearly-decreasing diameters, and these mesh with gears 26a ... 26u of equal diameters each weighted eccentrically with masses 30a, inversely proportional to gear revolutionary speed; gears 27a ... 27u are identical to gears 26a ... 26u. Non-vertical forces substantially cancel and vertical force impulses ensue at intervals corresponding to the rotational speed difference between successive gears 26. It is stated that the maximum deviation of shaft 12 should be within five degrees of shaft 10. To counteract the tendency of base-plate 20 to rise when the vertical impulse is upward the plate is sealed to the ground by, e.g., clay or an elastic apron 34 and a pump 36 creates a partial vacuum between the underside of the plate and the ground; alternatively mass-and-spring means having a resonant frequency less than the frequencies generated by the device, may be used, Fig. 3 (not shown). In another embodiment, pairs of eccentrically weighted and counter-rotating masses are on separate sub-chassis on the base-plate, each pair being rotated at a speed different from any other pair, Fig. 2 (not shown). The invention affords seismic pulse duration short enough to enable detection of thin beds of reflecting sub-strata.

Abstract: A washing machine in which an erroneous detection of the amount of water discharged from a tub of the machine is determined is disclosed. Preferably the signal from a pressure responsive water level detector is monitored and the time interval for a signal change indicative of a predetermined amount of water discharge is measured and compared with a preset time. Such an erroneous detection may occur with a tub having dehydration holes (or clearance) at its upper boundary and a drain hole at its bottom, when the drain hole becomes blocked by laundry, causing a reduction in pressure in an air trap. The machine may be provided with a lint filter (49, figure 9). The tub may have a tapered peripheral wall having a taper ratio of 1/60-1/40 with grooves which have a taper ratio which is different to that of the wall (see figures 10 and 11). The ratio of the total width of the grooves to the inner circumference of the tub is 1/9 or more.

Title: Method of automatically controlling the space charge in ion traps
Inventor: FRANZEN JOCHEN
IPC: H01J49/42
Filed: 1994-08-04
Abstract: The invention relates to a method of automatically controlling the space charge in ion traps when they are used as a mass spectrometer. If ionization conditions remain the same, space charge is proportional to the measured concentration of a substance; if there are rapid changes in substance concentrations, as can be found in coupling with gas chromatography for example, the space charge must be controlled to obtain spectra of consistent quality. The invention is based on the possibility of performing rapid consecutive scans and consists in utilizing the integrated ion currents of consecutive spectra to forecast by calculation the value of the ion generation rate at the time of the ionization phase for the next scan. Calculation may be based on linear, quadratic or cubic extrapolation but also on assumptions regarding the function of change of the concentration, and an adaptation of the function parameters.

Title: Correcting formation density measurements for non-source gamma radiation
Inventor: PLASEK RONALD E
IPC: G01V5/12
Filed: 1994-08-09
Abstract: A method for measuring formation density corrects for activated gamma radiation caused by other logging equipment that induces gamma radiation, e.g. accelerator neutron sources, and for naturally-occurring gamma radiation. The formation adjacent the borehole is irradiated with low energy gamma radiation from a density tool source. At least one gamma ray detection means is spaced longitudinally from the source. A gamma ray spectrum containing gamma rays that result from density source radiation and also activated gamma rays is detected by the detection means. The activated gamma rays are identified and subtracted from the total number of detected gamma rays which results in the gamma ray count from the density tool source. This gamma ray count can then be used in conventional density calculation processes to determine formation density.
