Title: Laser device for transmyocardial revascularization procedures
Inventor: MUELLER RICHARD L
IPC: A61B17/00
Filed: 1997-04-03
Abstract: An   apparatus   for   performing   a   laser   myocardial revascularization of a human heart comprises a hand-held device with an elongated flexible lasing assembly including an axially movable fiber bundle which can be placed into the chest cavity of a patient.  At the distal head end of the device laser energy from the distal end of the fiber bundle is initially reduced to form a relatively small opening in the epicardium of the heart.  The fiber bundle is moved through the opening so that lasing with full laser power takes place beneath the epicardium to form a larger channel through the myocardium that extends into the left ventricular cavity.   After the channel has been formed,  the optical fiber bundle is retracted from the channel and back through the small epicardium opening so as to minimize operative bleeding and allow sealing of the epicardium after the apparatus is removed.

Title: Arc-resistant switchgear enclosure
Inventor: KARNBACH ROBERT S
IPC: H02B13/025
Filed: 1996-09-06
Abstract: An improved arc-resistant switchgear enclosure is disclosed. The disclosed arc-resistant switchgear enclosure provides a cost effective structure to collect and channel the pressure and hot gases through the switchgear enclosure. In preferred embodiments, an internal arc chamber (30') is formed by assembling modules and creating a void within the center of the switchgear enclosure. As multiple compartments or modules (10, 12', 14, 24) for a switchgear enclosure are connected, an arc chamber is created within the enclosure. Upon initiation of an arc fault within a particular compartment, a relief flap (40, 42) or cover (42) for that particular compartment opens to channel the pressure and the gases into the internal arc chamber or directly through the top of the enclosure (100). Pressures and gases are vented into the internal arc chamber and flow horizontally through the arc chamber until a path to the top of the switchgear enclosure is reached. These pressures and hot gases are then channeled upward and safely out of the switchgear enclosure. Also disclosed is a ventilation system for an arc-resistant switchgear enclosure that provides natural ventilation while preventing any arc gases from entering the lower, ventilated compartment or compartments. This ventilation system permits the proper venting of pressurized gases originating in the lower ventilated compartment or compartments.

Title: A method of predicting tire performance on rain groove roadways
Inventor: SCHLABAUGH LARRY L
IPC: B60C19/00
Filed: 1998-04-23
Abstract: A method of testing a tire for rain groove wander is provided which allows a tire to be objectively tested in a laboratory wherein the objective test resultsclosely correlate with subjective field analysis type data, thereby allowing for the subjective tire performance to be predicted while precluding the need for subjective field analysis of the particular tire. The method also allows objective testing of a single tire size by varying the radial loading in the laboratory test set, thereby precluding the construction of multiple tire sizes each having the same tread design. The method simulates rain groove road conditions and correlates objective analysis data obtained via the laboratory test methodology with subjective field analysis data of rain groove wander tire performance of other tires, thereby providing a substantially accurate technique for identifying the subjective performance of the tire without having to conduct the field testing to obtain such subjective field analysis data. The method substantially reduces the cost required to design and test a prototype tire design and the time required to implement tire design testing.
