Patent GB-2291706-A (GB)
Title: Method and apparatus for producing a porosity log of a subsurface formation
Inventor: ALLEN LINUS SCOTT
IPC: G01V5/10
Filed: 1993-08-09
Abstract: A borehole logging tool (10) is lowered into a borehole traversing a subsurface formation and a neutron detector (19) measures the die-away of nuclear radiation in the formation. Intensity signals are produced representing the die-away of nuclear radiation as the logging tool (10) traverses the borehole. A signal processor (17), employing as least one neural network, processes the intensity signals and produces a standoff-corrected epithermal neutron lifetime signal to correct for standoff from the borehole wall (24) encountered by the detector (19) as the logging tool (10) traverses the borehole. The signal processor further generates a porosity signal from the standoff-corrected epithermal neutron lifetime signal derived from measurements in borehole models at known porosities and conditions of detector (19) standoff. A log is generated of such porosity signal versus depth as the logging tool (10) traverses the borehole. <IMAGE>

Patent GB-2293060-A (GB)
Title: Equalization of charge on series connected cells or batteries
Inventor: PACHOLOK DAVID R
IPC: H02J7/00
Filed: 1995-09-08
Abstract: A charge equalizer has a transformer 65 with windings 67 - 70 which have equal numbers of turns and are connectable across respective ones of series connected cell units 11, 12, 60, 61 by means of respective switches 72 - 75. An oscillator 80 operating at a high frequency (eg. 25 or 30 KHz) turns all the switches 72 - 75 on or off simultaneously, so that when the switches are on the voltage appearing across each winding 67 - 70 will be that of the cell unit having the highest charge and energy will be transferred from that cell unit via the transformer 65 to cell units of lower charge, with the energy transfer rate being proportional to the difference in the voltages between the respective cell units. The equalization is accomplished without requiring comparison of voltages across individual cell units. Each cell unit may be a single cell or a battery of connected cells. The cells may be, for example, alkaline manganese, lithium, or lithium-ion. The switching devices may be MOSFET's having self-capacitance between drain and source forming a resonant circuit with the associated winding, whereby resonant recovery of the energy stored in the transformer when the switches are on is effected when the switches turn off. The transformer may additionally include a second set of windings respectively connectable across the cell units by second switches, the second switches being all off when the first-mentioned switches are on, and vice versa (Fig. 5). Transistors 91, 96 respond to a control signal 90 so that the equalizer is only on when a battery charger (14, Fig. 1) is charging the cell units; alternatively the equalizer may be switched on by a charging current responsive relay (126, 129, Fig. 5). <IMAGE>

Title: Tachograph with phase correction
Inventor: BORLAND WILLIAM GRAHAM
IPC: G07C5/12
Filed: 1995-09-15
Abstract: A tachograph has a chart carrier 2 such as a turntable, driven by a motor 9, such as a stepper motor and the turntable is synchronised with the time shown on a clock 8. Means 16-18 are provided for correcting any phase error between the turntable position and the actual time, which means rotates the turntable to the correct position at which markings on a tachograph chart correspond with the time shown on the clock. Phase displacement can occur as a result of disengaging the drive from the turntable, e.g. when inserting the chart.
Patent GB-2294592-A (GB)
Title: Superconducting coils
Inventor: MORIYAMA HIDESHIGE
IPC: H01F41/04
Filed: 1995-10-03
Abstract: A superconducting coil 10 is formed by winding a superconducting wire 13 covered with an insulating material 12 around a winding frame 2a composed of such a material that its modulus of longitudinal elasticity is 50 (GPa) or greater, and its thermal contraction rate between room temperature and a temperature of 77 (K) is 0.35 % or above, while applying a tensile force to the wire. A bonding material 14 between the superconducting wires is then solidified by a heat treatment to reduce the contact surface pressure between the coil and the winding frame, thereby preventing the transition of the coil to normal conductive state due to heat generated by friction between the coil and the frame. The bonding material may be an epoxy resin. <IMAGE>

Title: Transporting offshore structures
Inventor: GIBSON PAUL FRANCIS
IPC: E02B17/00
Filed: 1996-07-23
Abstract: A transport structure 1 comprises a barge 2 supported by two pontoons 3,4. The barge 2 is a flooded barge having a ballast system, and is pivotably connected to the pontoons 3,4.

The structure to be decommissioned may be attached to the barge when the barge is in a substantially vertical position. The barge loaded with the structure may then be pivoted to a position lying in the horizontal plane just below the surface of the water in which position the structure 1 may transport the offshore structure to the appropriate location.

Title: Method of and apparatus for feeding sheet material
Inventor: WATKISS CHRISTOPHER ROBIN
IPC: B65H3/12
Filed: 1996-03-18
Abstract: A suction device for feeding sheets of material comprises a housing (38) connectable by a pipe (40) to a vacuum device and having apertures (54a, 54b, 54c, 54d, 58) through which a suction effect can be created. An eccentric roller (46) imparts a corrugation to the attracted sheet.

Title: IGBT with integrated control
Inventor: NADD BRUNO C
IPC: H01L29/739
Filed: 1996-11-15
Abstract: A monolithic IGBT and control circuit therefor are integrated into a common chip. The IGBT (19) is formed in a first area of the chip and the control circuit (30) is formed in a second laterally spaced area and in a P well (40). Hole injection from the P + substrate (50) into the P well (40) is prevented during IGBT operation, e.g. by providing a sufficient spacing between the areas; a P + collection region (80) between the areas; or an N + diffusion between the areas which is connected to the P + substrate. In the last case the areas may be surrounded by a common field termination structure, leaving a small surface bridge between, the two areas. Control conductors from the control area (30) to the IGBT area (19) cross over the bridge and not over the field termination. A lateral PNP transistor may be integrated in the chip and be connected to the central N + diffusion between IGBT and control areas to permit its connection to the P type substrate only when the IGBT area conducts.

Title: Method and apparatus for regulating flow of liquid
Inventor: MOLLER CARSTEN VEJBY
IPC: G01F15/08
Filed: 1998-07-14
Abstract: The invention relates to a method for filling liquid on and drawing off liquid from a collecting tank. The invention relates furthermore to an apparatus to be used by the method. The apparatus is provided with a by-pass in the shape of a pipe line 15 or a penetration in a valve body. The by-pass makes it possible to reduce a flow of liquid on commencing a filling and on terminating a drawing off. This causes that a flow of liquid through a flow meter 2 is much more calm and that the risk of air being led through the flow meter at the same time is substantially reduced. However, it is possible during most of a filling and during most of a drawing off to establish a higher flow to maximise the filling and the drawing off flow and thereby minimise the filling and the drawing off time.

The cracking point of each valve spool is determined by slowly opening the valve, with an appropriate setting of the other valves, and recording the spool position at which fluid flow through the valve commences. This spool position is then used as a control offset valve for the particular valve.
