Title: Fluid quantity gauging system
Inventor: ATKINSON HARRY
IPC: G01F23/296
Filed: 1996-09-10
Abstract: An ultrasonic fuel gauging system has several ultrasonic transducers 5, 6 mounted on the bottom 4 of a tank 1 which propagate diverging energy upwardly to the fuel surface 3. Each transducer receives a reflection of its own propagated energy from a region A, B of the fuel surface directly above, and also receives energy from reflections produced by energy propagated by other transducers in regions C of the surface midway between the transmitting and receiving transducer. The transducers are connected to an electronics unit 10, which includes transmit/receive units 15, 16 and a calculating unit 17, which calculates the heights of the liquid level at various regions by measuring the transit times of the pulses. Using two transducers, the heights of three different regions of the fuel surface can be computed, and the fuel quantity indicated on a display 11. In alternative embodiments, three or four transducers (figs 2 & 3) are used to make six or ten height measurements respectively.

Title: Flow restriction device for use in producing wells
Inventor: COON ROBERT JOE
IPC: E21B43/12
Filed: 1997-06-26
Abstract: The present invention provides a fluid flow control device 10 for controlling the formation fluid flow rates through a production string. The device 10 includes a generally tubular body 20 for placement into the wellbore. The tubular body 20 has a screen 22 at an outer surface for preventing sand from entering into tubular body 20. The fluid flowing through the screen 22 passes through a labyrinth 35. A slidable sleeve 38 on the labyrinth 35 controls the fluid velocity there through. The slidable sleeve 38 is moved by an electrically-operated device 45, such as a motor placed into the production string. The fluid leaving the labyrinth 35 passes to a tubing in the tubular body 20 for carrying the fluid to the surface. The flow control device 10 further may include a control circuit 50 in the production string for controlling the operation of the electrically-operated device 45. The control circuit 50 may communicate with a surface control unit, preferably a computer based system, which may provide commands to the downhole control circuit for causing the electrically-operated device 45 to adjust the position of the sleeve 38. The sleeve 38 may be positioned at any place on the labyrinth 35, providing accurate control over the flow rate. The surface control unit may communicate with the downhole control circuit 50 via a data communication link 48, which may be a cable or a transmitter/receiver system.

Title: Radiant heating device for use in repairing asphalt surfaces
Inventor: HUTCHINSON PAUL
IPC: E01C23/14
Filed: 1998-11-06
Abstract: A radiant heating device suitable for use in repairing asphalt surfaces comprises a closed frame (1) containing a downwardly-directed radiant heating surface (19) and at least four supporting legs (2) for the frame, the legs being slidably mounted whereby the extension of each leg below the frame may be varied individually.

Patent GB-2333913-A (GB)
Title: Control system for a plurality of fluorescent lamps
Inventor: SLOAN ALBERT EVERETT
IPC: H05B41/36
Filed: 1999-01-25
Abstract: Closure of a master switch 8 enables a common inverter 6 to supply a plurality of fluorescent lamp circuits 2 via a screened cable 10. The inverter 6 initially operates at a higher frequency (eg. 46 KHZ) for a short period (up to 5 seconds, eg. 500 msec.), after which the frequency is reduced to a lower running frequency (eg. 23 KHz). Each lamp circuit 2 has a switch 20 to connect a fluorescent lamp 12 to inverter 6 via a DC blocking capacitor 22, the lamp 12 being connected across a capacitor 26 of an L-C circuit 24, 26 which is resonant at the higher frequency. A further capacitor 28 connected in series with lamp heaters 14, 16 is effectively in parallel with capacitor 26, the L-C circuit formed by inductor 24 and capacitors 26, 28 being resonant at the running frequency. If a lamp switch 20 is closed before the main switch 8 is closed and the heaters of the corresponding lamp are intact, the lamp will not strike until after the inverter has switched to the running frequency, the heaters being preheated while the inverter is operating at its higher frequency. However, if either of the lamp heaters 14, 16 is burnt out, the lamp will strike during the initial period when the inverter operates at the higher frequency, the absence of a delay in striking the lamp giving a visual indication of a faulty heater. A lamp with intact heaters can also be struck by closing its switch 20 even after the inverter has switched to its running frequency. The arrangement allows a standard wall switch to be used for the switch 20, because high voltages do not appear across the switch 20, and the running frequency voltage appearing across capacitor 26 and lamp connection terminals 18 when a lamp is faulty or has been removed can be kept within safe limits. A faulty lamp can be replaced without affecting continued operation of the other lamps.

Title: Traction apparatus
Inventor: SIMPSON NEIL ANDREW ABERCROMBI
IPC: E21B37/04
Filed: 1997-08-15
Abstract: A traction apparatus (1A) includes at least one traction member (51) which engages a surface (10A) against which traction is to be provided. The traction member can move relatively freely in one direction over the surface but has high resistance to movement in the other direction.

There are preferably a large number of traction members which are in the forms of bristles in a brushlike part of the apparatus. The apparatus is suitable for use in down-hole tools. The bristles are bent in a first direction by being constrained in a hole facilitating movement in the opposite direction but preventing movement in the first direction.

Title: Single cycle two stage bypass valve
Inventor: MCGARIAN BRUCE HERMANN FORSYTH
IPC: E21B21/10
Filed: 1999-03-12
Abstract: A bypass valve (2) for selectively isolating the interior of a downhole assembly from its exterior comprises a body with a wall with at least one opening (20), a piston (30) slidably mounted adjacent the body such that a first position of the piston establishes a passage from the interior to the exterior of the body via the at least one opening (20), and a second position isolates the body's interior from its exterior, where means are provided for increasing, in response to a predetermined fluid pressure differential across the piston, the force exerted on the piston by a flow of fluid through the valve such that the resultant force on the piston is insufficient to move it to the second position. The force increasing means may be a second piston (36). Pistons (30) and (36) may abut compression springs (32) and (38) respectively. The predetermined fluid pressure is then the pressure sufficient to overcome the bias of spring (38), moving piston (36) to block a bypass passage (48) causing an increase in fluid pressure in bore (40), which may be detected at the surface, but which is insufficient to overcome the bias of spring (38).
