Title: Furnace and conveyor method for heating glass sheets.
Inventor: DEB SUGATO
IPC: C03B5/00
Filed: 1991-02-20
Abstract: The invention comprises a tunnel-type heating furnace of modular construction for heating glass sheets carried therethrough in succession on a series of aligned rollers. The furnace enclosure includes a lower section of generally rectangular cross-section beneath the rollers and an upper section, which is of generally elliptical configuration in cross-section, above the rollers. The upper enclosure section is vertically retractable by means of a jack mechanism to facilitate maintenance and changing of the rollers. The rollers include shafts at their opposite ends having bearings adapted to be received and supported in upwardly opening recesses in roll support plates extending along either side of the furnace. A toothed gear or sprocket is affixed to the end shaft at one end of each roller. The rollers are driven in groups by timing belts whose upper flights extend over and engage the toothed gears. Hold down assemblies removably carried by the roll support plates include cam rollers positioned intermediate each pair of toothed gears for urging the timing belts downwardly into driving engagement with the toothed gears. A differential heating assembly may be provided for modifying the heating pattern beneath the elliptical upper enclosure section.

Title: Process and apparatus for analysis of hydrocarbons by near-infrared spectroscopy.
Inventor: MAGGARD STEVEN M
IPC: G01N33/28
Filed: 1991-03-05
Abstract: Certain selected wavelengths in the near infrared spectra permit analysis of weight percent, volume percent, or even mole percent of each component, e.g. PIANO (paraffin, isoparaffin, aromatic, napthenes, and olefins), octane (preferably research, motor or pump), and percent of various hydrocarbons, e.g. alpha olefins. Analysis can be nearly continuous analysis on-line or at-line, as well as batch analysis, e.g. in a quality control laboratory. Preferably the NIR data is converted to a second derivative of the spectra and multiple linear regression performed to model the individual PIANO concentrations, and to predict physical properties of fuel blending components, e.g. research octane of reformate, etc.

Title: Electronic package using closed pore composites
Inventor: LAU JOHN WING-KEUNG
IPC: H01L23/498
Filed: 1992-05-06
Abstract: The electronic packages of the invention all employ the general materials scheme of a low dielectric constant material (low K material) mounted on a dense, high thermal conductivity (high TC) ceramic base. In this way, the low K material provides the signal transmission paths to and from the I.C. chips housed in the package and thus allows for higher signal transmission speed. The high TC material allows for heat dissipation out of the package. The dense base and/or the low K material may contain metallization in any desired pattern. The low K material is preferably a composite of closed pores in a glass-containing matrix.

Abstract: According to the state of the art, refuse dumps (1) which are already closed are made tight and sealed and their mummification is awaited. However, as a result of small leaks from outside and chemical and biochemical processes inside, a certain amount of seepage water nevertheless arises, which has to be pumped off and disposed of. In the case of the described method according to the invention, the old refuse dump (1) is left open on the upper side so that rainwater (34) penetrates, and the seepage water collecting at the bottom is pumped off (13) and after a certain cleaning treatment (14, 18) is preferably sprinkled (24) over the refuse dump again. As a result, numerous harmful substances can be broken down biologically in an economical manner and other harmful substances can be mineralised and thus bound insolubly. This treatment of the old refuse dump is carried out for 30 to 100 years until its complete harmlessness. <IMAGE>
