Title: A cover for a laryngoscope
Inventor: MOURKIDOU SOTIRIA
IPC: A61B1/273
Filed: 1996-02-21
Abstract: This invention is a cover (110) for a laryngoscope (112) which includes a generally elongated cylindrical handle (114), a branch member (118) and an insertion member (116). The cover (110) generally comprises an end sheath (128), a Y branch portion (130) connected to the end sheath (128) and two cylindrical sleeves (132, 134) connected to the Y branch portion (130). The end sheath (128) covers the insertion member (116) and has a closed end (136). The Y branch portion (130) covers an area adjacent the joint between the handle (114) and the branch member (118) and preferably comprises an expandable structure (137). Each of the cylindrical sleeves (132, 134) covers the handle (114) and the branch member (118), respectively. As a result, the laryngoscope (112) itself is shielded from contact with the interior of the mouth and the larynx. Once the cover (110) is used, it may be discarded. Accordingly, cleaning and sterilization of the laryngoscope (112) are substantially facilitated and hygienic operation of the laryngoscope (112) is improved.

IPC: A62C2/00
Filed: 1996-07-15
Abstract: A fire resistant industrial water cooling tower (20) is disclosed having normally closed passive vent structure (28) which vents the interior of the tower (20) above the area which is undergoing combustion to enhance suppression of the fire. The vent area is dependent upon the location and extent of the fire.

Title: Axial ejection in a multipole mass spectrometer
Inventor: HAGER JAMES W
IPC: H01J49/42
Filed: 1998-06-02
Abstract: A method of operating a mass spectrometer having an elongated multipole rod set, in which a two dimensional RF field radially contains trapped ions in a mass to charge range of interest, and in which the ions are contained axially by a barrier field on an end lens and to which a low voltage DC is applied. Trapped ions are axially mass selectively ejected by taking advantage of the mixing of the degrees of freedom induced by the fringing fields and other anti-harmonicities in the vicinity of the end lens. Thus, ions can be mass selectively ejected at the exit end at the same time as ions are being admitted into the entrance end of the rod set, thereby taking better advantage of the ion flux from a continuous ion source. The axial mass selective ejection is performed by applying an auxiliary AC voltage to the end lens, or to the rods themselves, or both, and by scanning either the auxiliary AC voltage or the RF voltage on the rod set. Trapped ions can be concentrated near the exit lens by applying an axial field in the direction of the lens, or can be depleted by applying the axial field in the opposite direction. The axial field can be oscillated to dissociate trapped ions.

Title: Pulse sequences and interpretation techniques for nmr measurements
Inventor: PRAMMER MANFRED G
IPC: G01R33/46
Filed: 1997-03-14
Abstract: An NMR pulse sequence and signal processing method is disclosed for measurement of fast decay response signals from materials containing a fluid state. The proposed pulse sequence and processing method are applicable in borehole NMR logging as well as measurements of attributes of man-made or natural materials. The disclosed pulse sequence comprises a series of short NMR pulse trains separated by intervals which are shorter than the time required for polarization of nuclear magnetization in bulk fluids of the fluid state. By stacking response signals to increase the signal to noise ratio, time domain data is obtained that generally corresponds to transverse decay components as short as about 0.5 ms. Various attributes of the materials being investigated can be derived in a single measurement.

When the hypertext mark-up language employed is HTML, text files are converted to an HTML representation. An HTML file is represented by a linked list of objects. Comment insertion markers and comment display objects are inserted at predefined points in the HTML linked list representation. The linked list is stored as a binary file and has a comment file associated with it. Access to the HTML file by reviewers and authors causes the regeneration of the HTML document by a Common Gateway Interface which recreates the linked list representation of the document from the binary file and which then generates HTML code from the linked list.
