Filed: 1992-08-07
Abstract: ABSTRACT OF THE DISCLOSURE     Common problems with composite panels of the foam core and metal facing type include water infiltration, failure to survive fire testing, and fragility. A relatively simple panel which affords a solution to the above mentioned problems includes a foam core with inner and outer metal facings thereon, a pair of spaced apart projections extending longitudinally of one side of the core defining male connectors, a pair of longitudinally extending, spaced apart grooves in the other side of the core defining female connectors for receiving the projections, the inner and outer facings terminating in the areas between the connectors so that there is core to core and metal to metal contact when panels are interconnected, a recess in an outer corner of the male connector side of the core, and a flange on the other side of the panel, whereby, when panels are interconnected side edge to side edge, the flange overlaps the recess leaving an expansion gap for fasteners, which are covered by the flange. Panels can be assembled to extend horizontally, in which case the bottom edge of the recess is inclined outwardly and downwardly to facilitate the escape of water from the gap.

IPC: E21B23/04
Filed: 1992-08-20
Abstract: ABSTRACT         In wireline operations, it is known to retrieve objects stuck in a well bore by application of a retrieval force to the object through a wireline and wireline pulling tool attached to the wireline and engaged with the object.  The present invention provides a wireline retrieving tool adapted to apply a large retrieving force on an object in a well bore without transmitting the force through the wireline.  The retrieving tool is adapted to be lowered into the well bore on the wireline until the pulling tool engages the stuck object.  Slips carried on the tool then anchor the tool against the easing of the well bore and a controlled retrieving force generated in the tool by an electric motor and hydraulic pump is applied between the easing and the pulling tool to dislodge the object.

Title: Gas spring
Inventor: COTTER JONATHAN P
IPC: F16F9/02
Filed: 1992-11-23
Abstract: A gas spring with a piston reciprocable in a chamber of a casing, a sealing assembly at the rear end of the casing through which the piston rod extends, and an end cap closing the rear end of the casing. The sealing assembly has a reinforcing ring having a sealing ring on one side and a wiper on the other side. The sealing ring and wiper are portions of a single body of elastomeric material molded to the reinforcing ring and integrally connected through one or more openings in the reinforcing ring. The casing wall is rolled radially inwardly over the sealing assembly into pressure contact with the reinforcing ring so that the sealing assembly becomes in effect an end cap for the front end of the casing. The rear end of the casing is rolled over the rear end cap by swaging into pressure contact with the end cap. A filler valve is disposed in the end cap. In use, the piston is normally retained on the rod by an enlargement having a diameter larger than the bore of the rod bearing so that in the unlikely event the piston separates from the rod the enlargement will be embedded in the bearing to retain the rod in the casing. If the piston separates from the rod a port in the rod vents to the atmosphere the compressed gas in the chamber.

Title: Method for producing glass thin film
Inventor: ISHIKAWA SHINJI
IPC: C03C17/02
Filed: 1993-03-16
Abstract: A method of producing an oxide glass thin film includes a process to obtain a transparent glass film, in which volatilization of additives in a porous film deposited is effectively suppressed and which can provide an oxide glass thin film having a desired arrangement of refractive index with a low optical loss. The method is for producing an oxide glass thin film, in which glass fine particles mainly containing SiO2 with additives are deposited on a substrate to form a porous thin film and then heated to form a transparent glass film. In the method, vapor of oxides of additive components is mixed in an atmosphere in which the porous thin film is heated to form the transparent glass film, whereby stopping the volatilization of the additives in the porous film deposited, preventing diffusion of the additives added to a core layer, and preventing the volatilization of glass transition temperature lowering components of additives (P2O5, B2O3. GeO2, etc.). By these, a desired arrangement of refractive index may be obtained, and an oxide glass thin film may be obtained while lowering the optical loss such as the optical scattering, which could be caused by bubbles in an unsintered portion.

IPC: C07C263/06
Filed: 1993-05-03
Abstract: ABSTRACT    CONTINUOUS MULTI-STAGE PROCESS FOR THE PREPARATION OF              (CYCLO)ALIPHATIC DIISOCYANATES The invention relates to a multi-stage process for the continuous phosgene-free preparation of (cyclo)aliphatic diisocyanates.  The process comprises conversion of (cyclo)-aliphatic diamines of the formula H2N-R1-NH2, wherein R1 represents a straight-chain or branched aliphatic hydrocarbon radical having from 6 to 12 carbon atoms or an optionally substituted cycloaliphatic hydrocarbon radical having 6 to 13 carbon atoms into the corresponding (cyclo) alkylenebisureas in a distillation reactor.  The bisureas are further reacted with a primary alcohol having 3 to 5 carbon atoms in a pressurised distillation reactor to obtain the corresponding (cyclo)alkylene biscarbamates.  The latter are thermally cleaved in the presence of a catalyst in a combined cleavage and rectifying column into the (cyclo)alkylene diisocyanates and alcohol in the liquid phase without using solvents. Compared with similar known processes, the process of the invention avoids the exposure of the reaction intermediates and products to high temperatures and ensures higher yields and lower energy consumption.
