Title: Sensor system with tunable narrow band filter.
Inventor: PRANCE ROBERT
IPC: H03F1/34
Filed: 2007-07-19
Abstract: The sensor system comprises a sensor or amplifier 12 with input 20, output 22, feedback path 16 from the output to the input, and a narrow band filter 14 in the feedback path. The bandpass or bandstop filter is tuned or tunable to either wanted signals or interference signals. The sensor and the filter are arranged so as to alter the relative amplitudes of the wanted signals and the interference signals in order to increase the relative amplitude of the wanted signals and reduce the relative amplitude of the interference signals. The reduction in dynamic range achieved permits the use of 16 bit rather than 24 bit A/D converters with sensitive sensors such as an induction magnetometer with search coil (122, figure 15) or electric potential sensors. The filter may comprise a plurality of filters. The filter may have variable quality factor Q, may comprise a twin T network, and/or be tunable using switched capacitors (figures 7,8). A delay may be included in the feedback path to give a comb filter characteristic.

Title: Variable displacement air hybrid vehicle
Inventor: MA THOMAS TSOI HEI
IPC: B60K6/12
Filed: 2008-06-18
Abstract: An air hybrid vehicle is described powered by a variable displacement internal combustion engine 16 which may or may not be equipped with a supercharger or turbocharger for boosting the engine 16. In the invention, power is taken from the vehicle to drive the engine 16 during deceleration or coasting of the vehicle. The engine 16 absorbs energy from the vehicle and produces boost air which is transferred and stored in a separate air storage tank 34 in the vehicle and this boost air is immediately available during acceleration or cruising of the vehicle for boosting the engine 16 set at a reduced effective displacement or at a maximum effective displacement according to the load demand from the vehicle. The vehicle achieves fuel saving and high performance by not driving any air charger when this boost air is used to supply the engine 16. To accommodate a large air storage tank 34, the body of the vehicle is adapted with air-tight volumes linked together including the trunk of the vehicle serving both as a general luggage space and a very large boost pressure air storage volume as soon as the trunk is closed.

Title: Method and system for determining coating performance
Inventor: HATTELAND KJELL
IPC: G01N17/02
Filed: 2008-06-24
Abstract: The present invention relates to a method and system for determination of coating performance of a nonconductive coating 3 applied to a metal structure 2 (e.g. a pipe) connected to a common terminal. The system comprises a first electrode 5 at a first location, a second electrode 6 at a second location axially displaced by a length, L, in relation to the first location, each electrode being in contact with a conductive fluid 4 (e.g. water electrolyte) with a specific (known) conductivity. A low-frequency voltage Vin is applied to the first electrode by means of a voltage source and the resulting potential Vout at the second electrode is measured by means of the voltage meter. According to the method, the mean leakage resistance Rle can be computed based on the low frequency voltage, the resulting potential at the second electrode, the specific conductivity of the fluid and the length, L, between the first and second electrodes. The mean capacitance, C, may also be determined by additionally measuring the resulting potential and phase difference at the second electrode. The mean capacitance may be determined from the applied AC voltage, the resulting potential and the phase difference at the second electrode, the specific conductivity of the fluid (electrolyte), the length L and the calculated mean leakage resistance. In further embodiments the mean leakage resistance Rle and mean capacitance C may be determined with the use of an equivalent simulation model 10 in which the simulated values are varied until they correspond with those measured at the second electrode. The disclosed method allows calculations for mean leakage resistance to be carried out for large leakage resistances (for modern coatings) which would previously been outside the range of previously known technology.

Title: Automatic level compensator
Inventor: FLETCHER JOHN KENNEDY
IPC: E02B17/02
Filed: 2009-11-04
Abstract: The invention relates to an automatic level compensator as a means of providing a stable relationship between the seabed and any buoyant surface vessel. The compensator comprises an inner member 5 secured under a flotation platform 28 and an outer member 7 secured to the sea bed 22 via base 16 in shallow water or an elevated structure 36 in deep water. As members 5 and 7 are expanded or compressed by the tidal influence on platform 28, water 15 is slowly drawn into, or discharged through aperture 12. As water is not compressible, the present arrangement provides a solid bond between seabed 22 and flotation platform 28. This union cannot be influenced by surface turbulence or tidal movement as the water inlet/outlet aperture 2 is too small and will only function with the prolonged time cycle of the ebb and flow tides. Water turbulence or any surface movement is too rapid to bring about any water discharge from within the unit.

Title: Separation of a mixture of molecules having different weights
IPC: B01D59/10
Filed: 1964-03-11
Abstract: 1,055,192. Separating molecules of different weights. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. March 11. 1964 [March 14, 1963], No. 10261/64. Heading B1L. A stream of molecules of different weights is fed from a moving aperture across a space to a moving collector means, whereby heavy and light molecules reach different parts of the collector by virtue of their low and high average speeds due to thermal agitation. Fig. 3 (not shown) illustrates a section through a slot shaped nozzle co-axial with collectors defined by walls (T). The curves represent the paths of molecules of various speeds, from the central nozzle to the surrounding cyclinder on which the collectors are situated, as the nozzle and cylinder rotate as one unit. The mixture collected by the collector opposite the nozzle will be enriched in light molecules, and the mixture collected 180‹ behind the nozzle depleted, relative to the mixture delivered to the nozzle Fig. 4 illustrates a similar arrangement, in which the stream emerges from a nozzle (E) at an angle to its axis of rotation (OX), which enables nozzle (E) to rotate slower than the nozzle in Fig. 3, to achieve the same result. In Fig. 7 a disc D forms an aperture L and rotates with a separator cylinder S on a common axis. Molecules are fed from a container R 0  through axially extending ducts, formed by co-axial cyclindrical and radial walls in a stationary cylinder C, and consequently move axially of the enclosure G through aperture L. Fast and slow molecules reach the left hand end wall of cylinder S at different angular positions therearound (Figs. 5, 6, not shown) and therefore enter different sectional apertures therein. Dividing walls in cylinder S deflect molecules entering three such apertures to two peripheral and one end wall aperture e 1 <SP>1</SP>, e 3 <SP>1</SP> and e 2 <SP>1</SP> respectively. Thus, the fast (light) molecules enter annular passage S 1  and container R 1 , the slow, heavy, molecules enter container R 3  and the intermediate mixture, of similar composition to the initial mixture, is returned to container R 0  for re-cycling. A vacuum (10<SP>-4</SP> m.m. of mercury) is maintained in enclosure G, and the flow of molecules from container R 0  to R 1 , R 3  is effected by heating R 0  and cooling R 1 , R 3 .
