Patent EP-0808820-A1 (EP)
Inventor: RAMPRASAD DORAI
IPC: B01J31/16
Filed: 1997-05-16
Abstract: Ethylidene diacetate is produced by the reaction of acetic anhydride, acetic acid, hydrogen and carbon monoxide at elevated temperatures and pressures in the presence of an alkyl halide and a heterogeneous, bifunctional catalyst that is stable to hydrogenation and comprises an insoluble polymer having pendant quaternized heteroatoms, some of which heteroatoms are ionically bonded to anionic Group VIII metal complexes, the remainder of the heteroatoms being bonded to iodide. In contrast to prior art processes, no accelerator (promoter) is necessary to achieve the catalytic reaction and the products are easily separated from the catalyst by filtration.
Patent EP-0834489-A1 (EP)
Inventor: CAMILLETTI ROBERT CHARLES
IPC: H01L23/58
Filed: 1997-09-25
Abstract: Thick opaque ceramic coatings are used to protect
delicate microelectronic devices against excited energy
sources, radiation, light, abrasion and wet etching
techniques. The thick opaque ceramic coating are prepared
from a mixture containing phosphoric anhydride, i.e.,
phosphorous pentoxide (P 2 O 5 ) and a pre-ceramic silicon-containing
material. It is preferred to also include
tungsten carbide (WC) and tungsten metal (W) in the coating
mixture. The coating is pyrolyzed to form a ceramic SiO 2 
containing coating. A second coating of plasma enhanced
chemical vapor deposited (PECVD) silicon carbide (SiC),
diamond or silicon nitride (Si 3 N 4 ), can be applied over the
thick opaque ceramic coating to provide hermeticity. These
coatings are useful on patterned wafers, electronic devices
and electronic substrates. The thick opaque ceramic coating
is unique because it is resistant to etching using wet
chemicals, i.e., acids such as H 3 PO 4  and H 2 SO 4  or bases.

Filed: 1997-08-01
Abstract: The system (1) for the packaging of two separate components (A,B), their mixing and subsequent dispensing comprises a container (2) with two compartments (4,5). A removable plug (8) separates the two compartments before use. The container has a dispensing ferrule (18) and a rotating operating part (17) able to prevent, in its initial position, opening of the ferrule. An axially movable coupling (20) causes rotation of the operating part to act on the plug and give communication between the compartments. The coupling has the shape of a tubular skirt fixed to the dispensing ferrule. The skirt screws on the container and is connected by a sliding channel to the operating part.

Abstract: An improvement is disclosed for a boiler leak system that (a) measures fluid input into the recovery boiler system, (b) measures fluid output from the recovery boiler system, and (c) calculates fluid leakage loss based on an average difference between the measured fluid input and output values. The improvement increases the accuracy and responsiveness of calculating and interpreting the difference between the input and output fluid flow of the boiler. One aspect of the invention is an improved method which includes (1) compensating for the effects of boiler drum swelling and shrinking; (2) using multiple time frames to calculate the average differences between input and output such that a balance is struck between a highly responsive leak indication (short time frame) and a highly accurate leak indication (longer time frame); and/or (3) indicating a leak only after a predetermined certain sequence of significant differences between input and output is reached. Other aspects of the invention involve an apparatus and system for performing the above method.

pump structure (14) to the engine. An outlet of the engine is constructed and arranged to
communicate fluid coolant with the inlet to the heat exchanger module (18). The outlet of the heat
exchanger module (18) is fluidly connected with an inlet to the pump structure (14) to return the fluid
coolant to the pump structure (14). The cooling circuit includes bypass structure (43) constructed and
