Title: Oligo(2-alkenyl azlactones)
Inventor: HEILMANN STEVEN M
IPC: C08F34/00
Filed: 1991-09-16
Abstract: This invention provides novel azlactone-functional oligomers of 2-alkenyl azlactones in which oligomerization has occurred predominantly via the 2-alkenyl group. Oligomerization of the 2-alkenyl group provides oligomers having 2 to 15 mer units with predominantly carbon-carbon backbone segments. Oligomerized in this fashion, the novel compositions possess azlactone groups which can be reacted with nucleophiles in the normal ring-opening sense. The oligomers are prepared by a novel process in which both Lewis and Bronsted acidic catalysts are effective. The reactive oligomers find utility as crosslinking agents for polymers containing azlactone-reactable nucleophilic groups.

Filed: 1993-11-05
Abstract: METHOD FOR THE REPAIR OF EXISTING MANHOLES        USING ELASTOMERIC MATERIALS               ABSTRACT OF THE DISCLOSURE This invention relates to a method of repairing existing manholes and similar structures by applying a fast-curing elastomeric material using spray techniques whereby a homogeneous, non-porous, and monolithic coating or lining is formed. The fast-curing elastomeric material can be applied directly to existing substrates, which may comprise of concrete, brick, tile, mortar, and metal surfaces normally found in sewer manholes and catch basins, sewer and drainage pipes, parking decks, bridge piers and footings, holding ponds, bridge trusses, culverts, gratings, and the like and does not require any formwork. More preferably, the substrate surfaces are first cleaned and primed to improve the bond of elastomeric coating to the substrate. The most preferred primer is an aqueous solution of silane, preferably containing 10% to 30% silane. The elastomeric coatings provide effective surface protection against water infiltration, wear, and corrosion and can be applied in a single operation to horizontal, vertical, and overhead surfaces. The elastomeric materials are prepared by initiating the reaction of an isocyanate-terminated compound or polymer with an amine-terminated polymer or an aliphatic or aromatic diamine immediately before applying the elastomeric material to the surface to be coated. Preferably the reactive component (i.e., isocyante-containing1 and amine-containing materials) are mixed directly in the spray gun used to apply the elastomeric material.

IPC: G06F17/50
Filed: 1994-10-12
Abstract: A self-checking circuit and a method of its configuration are useful for achieving highly reliable system configuration.      A logic circuit having an error detection function has function blocks for feeding out a plurality of signals at least duplexed. The system compares the output signals of the function blocks and detects an error on the basis of the results of the comparison. A synthesizing system superimposes inherent waveforms assigned in advance to the respective output signals of the function blocks onto the output signals of one of the function blocks. The inherent waveforms are orthogonal waveforms generated by an orthogonal waveform generator circuit. The logic circuit also compares the signal output of the synthesizing system with the signal output of the other function block to detect the error. The whole circuit including the function blocks are judged normal only if waveforms inherent to both the output signals exist.

Title: Synthesis Gas from Particulate Catalysts, and Admixtures of Particulate Catalysts and Heat Transfer Solids
Inventor: DAVIS STEPHEN M
IPC: C01B32/40
Filed: 1994-04-26
Abstract: A process utilizing a particulate catalyst, or particulate catalyst admixed with particulate heat transfer solids for conducting high temperature fluidized bed syn gas operations. Hydrogen and carbon monoxide are produced from a low molecular weight hydrocarbon by contact thereof, at high temperature in the presence of oxygen, or steam and oxygen, with a fluidized bed comprising said particulate solids. In one of its forms, barium hexaluminate is employed as a heat transfer solid, in concentrations ranging generally from about 10 wt% to about 99.9 wt%, in admixture with a particulate catalyst containing a metal, or metals, component catalytic for the production of hydrogen and carbon monoxide from low molecular weight hydrocarbons contacted with a fluidized bed of the catalyst at high temperature hydrothermal conditions. The catalyst, suitably one having a barium hexaluminate carrier component, is employed in concentration ranging generally from about 0.1 wt% to about 90 wt%. Such an admixture provides a particularly useful catalytic contact mass for conducting fluidized bed synthesis gas generation operations. This type of bed promotes continuous, highly efficient heat and mass transfer within the reacting gas phase. The presence of the catalyst having a barium hexaluminate carrier component, or barium hexaluminate heat transfer solid as a bed component maintains excellent bed fluidization characteristics, suppressing the normal tendency of the catalyst to sinter or agglomerate; tendencies which promote defluidization of the bed.      Moreover, the heat transfer particles of the bed are highly attrition resistant, and are chemically compatible with the catalyst particles of the admixture.

Abstract: A thin-film, flat panel, pixelated detector array serving as a real-time digital imager and dosimeter for diagnostic or megavoltage X rays or gamma rays, including a plurality of photodiodes made of hydrogenated amorphous silicon arrayed in columns and rows upon a glass substrate. Each photodiode is connected to a thin film field effect transistor also located upon the glass or quartz substrate. Upper and lower metal contacts are located below and above the photodiodes to provide the photodiodes with a reverse bias. The capacitance of each photodiode when multiplied by the resistance of the field effect transistor to which it is connected yields an RC time constant sufficiently small to allow fluoroscopic or radiographic imaging in real time.
