Patent GB-2467168-A (GB)
Title: A gas bearing and a method of manufacturing such a gas bearing
Inventor: DUPONT RALF
IPC: F16C32/06
Filed: 2009-01-26
Abstract: A gas bearing 100 has pressurised axially extending chambers 110 in a housing 102 which has a shaft bore 104 therein, the axially extending chambers 110 being in fluid communication with a bearing surface 108 that defines the bore via laser-drilled capillaries 118. The end 122 of each laser-drilled capillary 118 at the bearing surface 108 is flared such that the narrowest portion of the capillary is set back from the bearing surface 108. This shape can ensure that the load carrying function of the bearing 100 does not fail during shaft eccentricity by ensuring that pressure restriction must happen within the capillary and not the gap between the shaft and the bearing surface 108. The bearing surface 108 may face in an axial and/or radial direction with respect to the shaft. The axially extending chambers 110 may be pressurised axially such that the outer circumference of the housing 102 is unbroken and hence usable for other purposes.

Title: Tracer Logging Tool
Inventor: OJUKWU KELECHI ISAAC
IPC: E21B49/00
Filed: 2009-04-15
Abstract: A tracer logging tool for diagnosing water and oil entry zones in oil well comprises a hollow mandrel with a tracer material 7 coated on the inside thereof, an impeller 10 to impose a rotation on the fluid flowing through the tool to maximise the contact between the fluid and the tracer as the fluid flows through the mandrel, and a torque balance to prevent the logging cable from turning. The tool may further comprise a connector head 1 for attaching the tool to any logging cable 12 via a rope socket connection 13. The connector head attaches to protective flow barrel 6, which houses an oil-tracer stem 5 and the water-tracer mandrel. Hydrophobic 4 and hydrophilic solid-state tracers 8 are pasted onto the exterior of the stem and the interior of the mandrel. Both oil and water phases will absorb the tracers as well fluid flows through the barrel. Flow ports 2 act to balance the torque induced by the spinning fluid.

Title: Frac pack casing saver
Inventor: CLEM NICHOLAS J
IPC: E21B43/04
Filed: 2009-04-29
Abstract: A deflection device keeps high velocity gravel slurry flow from directly impinging the wellbore wall in open hole and breaking loose the filter cake coating on the wall or, in a cased hole, prevents the direct impingement of gravel slurry on the casing which can cause wear from erosion. The slurry exist from an intermediate annulus in a crossover that is fitted with movable members that can be pivotally mounted for rotational displacement by the pumped slurry to act as a deflector to prevent or minimize direct impingement on the wellbore wall or casing. When the flow stops the deflectors can pivot back to their original positions. The deflectors can be simply replaced when worn.

Filed: 1975-03-11
Abstract: 1485700 Comparator HUGHES AIRCRAFT CO 11 March 1975 [11 March 1974] 10169/75 Heading G4M A comparator circuit contains a plurality of cascade switching circuits each of which receives a respective input from corresponding stages of two binary numbers, e.g. f 1  and g 1 , f 2  and g 2  &c. The g and f signals control the "tree" formed by transistors 41-46 so that a current I 0  flows on line 26 if the two bit values are identical and on line 28 if they are different. If f 1  is high transistors 41 and 45 are enabled and if g 1  is high transistor 46 is enabled. If f 1  and g 1  are low transistors 42, 44, 43 are enabled. A programmable current source 70 contains switching circuits 71, 72, 73 arranged to have switching current values that are multiples of the current I 0 , e.g. 71 may be I 0 , 72, 2I 0  and 73, 4I 0  so that a binary signal Z 0 , Z 1 , Z 2  can control the currents Ip 1 , Ip 2 . The currents Ip, Ic are supplied by common base transistors 64, 66 the collectors of which feed two inputs of a difference amplifier 24<SP>1</SP> which produces an output signal if the input at terminal 69 is more positive than that at 70. The current source 70 contains a source 75 providing an offset of 0À5 I 0  between transistor 64, 66. The source 70 provides a threshold value such that a signal is only produced from the difference amplifier if the number of bits in the two numbers that correspond with each other differ from the bits that do not correspond by more than the threshold value, e.g. if Z 0 , Z 1 , Z 2  equal 0, 1, 0 then Ip 2  - Ip 1  =2 À5 I 0  and so Ic 1  must exceed Ic 2  by a value of 3I 0  for amplifier 24<SP>1</SP> to produce a signal.
