Patent CA-2116344-A1 (CA)
Title: Mass spectrometry method using supplemental ac voltage signals
Inventor: KELLEY PAUL E
IPC: H01J49/42
Filed: 1992-08-28
Abstract: A mass spectrometry method in which a supplemental AC voltage signal having at least one high power frequency compo-nent, and at least one low power frequency component, is applied to an ion trap. Each high power component has an amplitude sufficiently large to eject one or more selected ions from the trap, by resonantly exciting the ions. Each low power component has an amplitude sufficient to induce dissociation (or reaction) of one or more selected ions, but insufficient to resonate the ions for detection. The frequency (or band of frequencies) of each high and low power frequency component is selected to match a reson-ance frequency of ions having a desired mass-to-charge ratio. Each low power component is applied for the purpose of inducing dissociation or reaction of specific trapped ions, which may be parent, daughter, reagent, or product ions, and each high power component is applied to eject undesired products of each such dissociation or reaction process from the trap. In accordance with the invention, a supplemental voltage signal having appropriately selected high and low power frequency components is applied to a trap during an (MS)n or Cl, or combined Cl/(MS)n, mass spectrometry operation.

Title: Retrievable whipstock anchor assembly
Inventor: DINHOBLE DANIEL E
IPC: E21B7/08
Filed: 1995-01-13
Abstract: A retrievable whipstock/anchor assembly is used to allow drilling of additional wellbores from an original or primary wellbore (which may be a highly deviated or horizontal open wellbore). The retrievable whipstock assembly is comprised primarily of two sections, an anchor section and a whipstock section. The anchor section provides resistance to compression and rotation forces, and provides rigidity for the whipstock. The whipstock provides a support face for drilling the additional wellbores. The whipstock can be oriented radially to allow drilling at any radial angle, and can be set at any depth. Anchoring of the retrievable whipstock assembly is provided by means of an inflatable element which expands to grip the inside wall of the wellbore. Radial orientation can be provided by rotating the retrievable whipstock assembly from surface or other means until the whipstock is at the desired orientation. Radial orientation can also be provided by an orienting guide in the top of a lower completion into which the retrievable whipstock assembly can be landed. In accordance with an important feature of this invention, the retrievable whipstock assembly is run-in the wellbore using a novel run-in tool while the retrievable whipstock assembly is retrieved from the wellbore by means of a novel retrieving tool, both of which attach to the whipstock.  Both the run-in and retreiving tools include a novel cylindrical housing which acts as a protective shroud over the whipstock thereby precluding or minimizing damage during run-in and/or retrieval.
