Filed: 1998-02-03
Granted: 2005-12-06
Abstract: A surgical instrument (10) is adapted to contact tissue of a patient, and to provide traction with the tissue in order to inhibit migration of the instrument relative to the tissue. The instrument may include a pair of opposing jaws (16, 18) with at least one of the jaws (16, 18) comprising a substrate having a particular surface facing the tissue, and a plurality of discrete elements (26, 28) disposed on the particular surface for increasing the traction of the instrument relative to the tissue. These discrete elements (26, 28) may include a multiplicity of granules, bristles, or projections, and may be formed of materials having various properties such as hydrophilic characteristics. The discrete elements in the form of bristles can be oriented too so that the column strength of each bristle provides increased traction in a predetermined direction.

Title: Recycling cooking oven with catalytic converter
Inventor: WINKELMAN EARL R
IPC: H05B6/80
Filed: 1998-05-27
Granted: 2004-03-30
Abstract: A recycling cooking oven (10) providing a substantially closed environment, includes a thermal plenum (20), for supplying a stream of hot air into a cooking chamber (22) and for receiving a stream of hot air from the cooking chamber, the thermal plenum (20) maintaining a reservoir of hot air therein. The cooking chamber (22) of the oven supplies a stream of hot air into the thermal plenum (20) and receives a stream of hot air from the thermal plenum, the cooking chamber (22) cooking foods therein at least partially with a stream of hot air and such foods adding oxidizable components to the hot air of the stream. A blower (24) and ducting (26) cause the stream of hot air to circulate in substantially a continuous travel path including the thermal plenum (20) and the cooking chamber (22). A catalytic converter (50) is disposed in the travel path of the stream of hot air, downstream of the cooking chamber (22) and upstream of the thermal plenum (20), for flamelessly oxidizing oxidizable components in the hot air of the stream leaving the cooking chamber (22), thereby both to remove them from the hot air of the stream and to release at least some additional heat energy into the hot air of the stream.

Abstract: A railroad track has a heavier rail section and a lighter rail section. Compromise rails join the heavier and lighter rails. Each compromise rail has a head with a heavier end to match the profile of the heavier rails and a lighter end to match the profile of the lighter rails. Each compromise rail is symmetrical about a straight center line extending from one end to the other. The width of the compromise rail tapers uniformly from the lighter end to the heavier end. This results in a slightly different gauge along the compromise rail section from the standard gauge. The different gauges are accommodated by adjusting the gauge at an end portion of the lighter rail section and at an end portion of the heavier rail section.

Abstract: This invention is directed to a downhole method and apparatus for simultaneously determining the horizontal resistivity, vertical resistivity, and relative dip angle for anisotropic earth formations. The present invention accomplishes this objective by using an antenna configuration in which a transmitter antenna (T1) and a receiver antenna (R1) are oriented in non-parallel planes such that the vertical resistivity and the relative dip angle are decoupled. Preferably, either the transmitter or the receiver is mounted in a conventional orientation in a first plane that is normal to the tool axis, and the other antenna is mounted in a second plane that is not parallel to the first plane. Although this invention is primarily intended for MWD or LWD applications, this invention is also applicable to wireline applications.
