Title: Power management system for battery powered computers
Inventor: YOUNG STEVEN JAY
IPC: G01R31/36
Filed: 1992-07-30
Abstract: The system can determine which one of a plurality of battery packs has boon coupled to the system, and thereafter, the system recalls from storage the recommended charging pattern for the particular battery pack 30 and begins to charge the battery. When the computer is running off the battery pack, a charge counter 35 measures the total amount of charge supplied to the computer. When the difference between the total amount of charge supplied to the computer and the total charge available from the battery reaches a predefined limit, a low power indication is given. The charge counter comprises an integrating capacitor (354), (Fig 4), charged by an amplifier (353) having an input connected across a current measuring resistor (351). At periodic intervals the voyage on the capacitor (354) is sampled to update a running total of charge level and then the capacitor (354) is discharged. The charging circuit may have a switch (204), (Fig 6), which chops a d.c. supply into a square wave of constant amplitude which is input to a transformer (207) providing a sinusoidal output of amplitude dependent on the duty cycle of the switch (204). The output of transformer (207) is rectified to charge the battery. A signal from a square wave generator (217) is averaged by a RC circuit (219) and compared (213) with the battery voltage to control the duty cycle of switch (204) 50 that the battery is charged at a gradually decreasing rate or its charge increases. <IMAGE>

Title: Analog to digital converter
Inventor: GOYAL RAMESH CHANDRA
IPC: H03M1/16
Filed: 1992-08-13
Abstract: A high resolution analog to digital (A/D) converter amplifies and filters a magnitude difference between a pulse width modulated offset voltage Voff and an input voltage Vin to produce an amplified filtered difference voltage Vo, the duty cycle of offset voltage modulation being adjusted such that the magnitude of the difference voltage Vo is within a narrow input voltage range of a recirculating remainder A/D converter 18. The amplified, filtered difference voltage Vo is converted to digital data D1 by the recirculating remainder A/D converter 18. A microprocessor 20, which controls the offset voltage, combines the result with the magnitude of the offset voltage to produce a comparatively high resolution digital representation of the input voltage. During a first pass an auto ranging circuit 12 divides the input voltage Vin by a factor of 1,000 and supplies the resulting voltage directly to A/D converter 18. In response to the output of the A/D converter 18 during the first pass the microprocessor 20 adjusts the gain of autoranging circuit 12 to provide a voltage which is a substantial portion of the input voltage range of the A/D converter 18 during a second pass. For the third pass switches S1 and S2 are closed and switch S3 opened; the offset voltage Voff represents the output of A/D converter 18 during the second pass less a fixed non-zero amount. The output is derived from the outputs of the A/D converter during the second and third passes and the gain factor supplied to the autoranging circuit 12. <IMAGE>

Title: Measurement of magnetic field by exposure of a magnetic crystal to the field    and an applied rotating field
Inventor: VERONKO ALEXANDER I
IPC: G01R33/02
Filed: 1992-09-15
Abstract: In the measurement of a magnetic field by placing a body of magnetic crystal material in the field to be measured, applying a further magnetic field of cyclically varying direction to the body and detecting cyclical fluctuations in the magnetic field in the body, the magnitude of which are proportional to the strength of the magnetic field to be measured, the crystal material (eg. LuxY3-xFe5-yScyO12 where y is 0.5 - 0.7, x is 0 - 1.2) defines a single magnetic domain (ie all the magnetic moments of the body are aligned) which remains constant. Body 3 is mounted on substrate 4 adjacent coils 1 and 2 so as to be exposed to a rotating field of fixed frequency established by passing current through the coils and to the field to be measured. The detecting means detects the cyclical fluctuations at twice the fixed frequency. The problem of noise swamping such fluctuations is alleviated. <IMAGE>

Title: Installing underwater storage tank
Inventor: NEDREBO OYVIND
IPC: E02D23/02
Filed: 1994-12-09
Abstract: In a method of installing a storage tank 1 for petroleum products on the seabed, a liquid less dense than water (eg a light petroleum product) is used as ballast and is transferred to and from the tank via a loading buoy 23 connected to a tanker 26. Initially the tank 1 is completely filled with a light petroleum product, and air is simultaneously ventilated from the tank 1 which assumes a stable, floating position. Valves are opened in the bottom part of the tank 1 to admit seawater while the light fluid ballast is simultaneously transferred from the upper part of the tank back to the source 26 through conduit 24. Descent is controlled by devices 12, 14 until the skirts 2 of the tank penetrate the seabed 21. Further penetration is carried out by replacing the light fluid in the tank with seawater, and final penetration is effected by providing an underpressure in the volume delimited by the seabed 21, the skirts 5 and the bottom face of the tank. After installation, the buoy 23 and flow line 24 are used in the normal operation of the tank. <IMAGE>

Title: Prestress grout bag
Inventor: HOWELL MARK
IPC: E21D15/48
Filed: 1995-12-20
Abstract: A prestress grout bag of the type suitable to apply a prestress force to a mine support, such as a pack or prop, when inflated with grout under pressure, the bag including a one-way filler valve 12, in a wall of the bag, through which grout can be pumped into the bag to inflate it. The filler valve has a poppet closure 36 and annular valve seats 30, 32, the valve seat 30 being more flexible than the valve seat 32. When the delivery hose of the pump is disconnected, and assuming that the bag has been inflated to the desired pressure, the force acting on the poppet closure from inside the bag forces the head 38 of the poppet closure through the opening in the flexible valve seat 30. The space between the valve seats 30, 32 fills with grout and the stem 40 of the poppet closure moves until the head 38 seats against valve seat 32 with the legs 42 extending out of the valve. The filler valve thus has the facility to provide a readily visible indication that the bag has been inflated to a predetermined pressure. <IMAGE>
