Abstract: A rotary drill bit for drilling a curved subterranean borehole.  In one embodiment, the drill bit comprises a side portion, a plurality of cutting elements that produce a lateral force on the drill bit in response to the rotation of the drill bit in the borehole, and bearing means. The bearing means is located on the side portion of the drill bit and contacts the borehole wall during drilling to receive a reactive force that is from the borehole, that is in response to the lateral force and that is directed to a location adjacent to the uphole end of the side portion of the drill bit. The reactive force and the lateral force form a downhole-moment that is about the drill bit and that is opposed by an uphole-moment having a force component that is directed at the flexible joint. The uphole end of the bearing means is located relatively close to the cutting elements such that the magnitude of the downhole-moment and the magnitude of the uphole-moment are minimized.

Title: Rod guide with enhanced erodable volume
Inventor: O'HAIR DAN E
IPC: E21B17/10
Filed: 1994-03-30
Granted: 1998-09-29
Abstract: A rod guide molded in intimate contact with a sucker rod increases the amount of rod guide material available for wear. Adequate bypass area is provided so as not to impede the efficient movement of the rod and guide in tubing, yet more material for wear significantly lengthens the useful life of the rod guide. In a preferred embodiment, the rod comprises two guide elements, each with two lobes or vanes. The vanes of the two elements are opposed by ninety degrees for smooth operation and stability of the guide. Each lobe has an exterior contact surface with a circular radius of curvature that matches that of the tubing into which the guide is to be inserted.

Title: Method of operating a fuel cell
Inventor: DUDFIELD CHRISTOPHER DAVID
IPC: H01M8/04
Filed: 1995-05-24
Granted: 1999-04-13
Abstract: A fuel cell which is operated at a temperature which is not greater than substantially 250°C, has an electrolyte which can be a solid polymer electrolyte, a liquid phosphoric acid electrolyte, or a liquid alkaline electrolyte, and a cathode and an anode each comprising a platinum catalyst.  Hydrogen fuel gas is supplied to the anode and a gaseous oxidant, for example oxygen is supplied to the cathode.  The cathode and anode are both connected to first and second circuits in parallel.  The first circuit includes a load to be powered by the fuel cell and a first switch.  The second circuit includes a battery and a second switch.  The switches are operated by a control.  When the first switch is closed the cell powers the load and second switch is open.  When the first switch is open the second switch is closed so the battery applies a reverse D.C. potential to the anode and cathode.  The first switch is closed and the second switch is open for a time period T1 which is substantially at least ten times greater than time period T2 for which first switch is open and the second switch is closed.  The time period T2 does not exceed substantially 0.25 seconds.  The switches can be relays or solid state electronic switch arrangements.

Title: Fugitive colour fire retardant composition for aerial application
Inventor: CROUCH ROBERT L
IPC: A62D1/00
Filed: 1995-07-18
Granted: 2005-02-22
Abstract: In a fugitive colour fire retardant composition, the colourant initially colours the composition to a hue which contrasts with the hue of ground vegetation. A non-fugitive component is included in the colourant, in an amount which is sufficient to provide improved aerial visibility when the composition is first aerially applied to the vegetation. However, the amount of non-fugitive pigment is less than an amount which would prevent the composition from fading after application to an acceptable hue.

Title: Method for increased sensitivity of radiation detection and measurement
Inventor: MILLER STEVEN D
IPC: G01T1/105
Filed: 1994-03-07
Granted: 2001-04-17
Abstract: Dose of radiation to which a body of crystalline material has been exposed is measured by exposing the body to optical radiation at a first wavelength, which is greater than about 540 nm, and measuring optical energy emitted from the body by luminescence at a second wavelength, which is longer than the first wavelength.  Reduced background is accomplished by more thorough annealing and enhanced radiation induced luminescence is obtained by treating the crystalline material to coalesce primary damage centers into secondary damage centers.
