Abstract: The invention relates to a process and device for relably preventing the contamination of the tapping steel from a converter by flush slag. To this end a plastic, deformable plug (1, 8) of fireproof material containing silicate and oxide components and a suitable binder is used. The plug (1, 8) is inserted with the aid of a fitting device into the tapping until its front surface closed off by a cone-shaped crush-plate (2, 5) is virtually flush with the inside of the converter, on being crushed completely fills the diameter of the tapping aperture (10) and thus provides a plane such that the flush slag is reliably guided over the tapping when the converter is tipped. Owing to the process used, the novel plastic plug (1, 8) fits a wide range of tapping aperture diameters. The plug (1, 8) is rapidly removed by the molten steel flowing off through the cone channel (5) so that the steel flows into the tapping pan.

Abstract: A membrane probing assembly includes a support element having an incompressible forward support tiltably coupled to a rearward base and a membrane assembly, formed of polyimide layers, with its central region interconnected to the support by an elastomeric layer. Flexible traces form data/signal lines to contacts on the central region. Each contact comprises a rigid beam and a bump located in off-centered location on the beam, which bump includes a contacting portion. After initial touchdown of these contacting portions, further over-travel of the pads causes each beam to independently tilt locally so that different portions of each beam move different distances relative to the support thus driving each contact into lateral scrubbing movement across the pad thereby clearing away oxide buildup. The elastomeric member backed by the incompressible support ensures sufficient scrub pressure and reliable tilt recovery of each contact without mechanical straining of the beam. In an alternative embodiment, the contacts comprise conductive beams each supported on a loose U-shaped flap formed in the membrane assembly where each flap and beam is tiltably supported in inclined position by an elastomeric hub interposed between the flap and support.

Abstract: An improved restraint device is provided which is characterized by its relative ease of use and comfort to occupants while providing effective and enhanced protection to occupants of motor vehicles or the like. The restraint device includes an open ended tubular guide member which is generally cylindrical or elliptical in cross-section and in which the interior surfaces of the tubular member define a longitudinal passageway for receiving and engaging portions of both the shoulder harness and lap portions of a three-point vehicular restraint system. The guide member exerts a laterally displacing force on the shoulder harness portion of a three-point restraint system to re-orient the shoulder belt for use by adults of relatively small stature or children. In this manner, the repositioning of the shoulder belt for use by children in particular may be accomplished without adversely displacing the relative position of the lap belt particularly during impact conditions. The advantages of the restraint device are accomplished without adversely affecting the automatic adjustment capabilities of the existing automotive restraint apparatus or without requiring extensive modifications to the existing restraint.

Abstract: This application is directed to novel fluorinated polymers and prepolymers derived from mono-substituted oxetane monomers having fluorinated alkoxymethylene side-chains and the method of making these compositions. The mono-substituted fluorinated oxetane monomers having fluorinated alkoxymethylene side-chains are prepared in high yield by the reaction of a fluorinated alkoxides with either 3-halomethyl-3-methyloxetane premonomers or aryl sulfonate derivative of 3-hydroxymethyl-3-methyloxetane premonomers. Preparation of a mono-substituted 3-bromomethyl-3-methyloxetane premonomer via a simple, high yield process amenable to commercial scaleup is also disclosed. The fluorinated oxetane monomers of this invention can be readily homo/co-polymerized in the presence of a Lewis acid and polyhydroxy compounds to obtain hydroxy-terminated polyether prepolymers having fluorinated alkoxymethylene side chains. Additionally, the fluorinated oxetane monomers can be copolymerized with non-fluorinated monomers such as tetrahydrofuran to give polyether prepolymers with improved hydrocarbon compatibility. These prepolymers are polydisperse and exhibit number average molecular weights from 5,000 to about 50,000. These prepolymers are amorphous oils with primary hydroxy end-groups and thus function efficiently as the soft block for the synthesis of a variety of thermoset/thermoplastic elastomers and plastics having the characteristics of very low surface energy, high hydrophobicity, low glasss transition temperature and low coefficient of friction. The polyurethanes derived from the prepolymers of this invention are elastomeric and, in addition to the above characteristics, exhibit high moisture resistance, high tear strength and excellent adhesion to a variety of substrates.

Abstract: Crude phthalic anhydride (PSA) is catalytically produced from oxygen-containing gas and orthoxylol or naphthalene at temperatures in a range from 300 to 500  DEG C. The mixture containing gas and PSA vapour withdrawn from the reactor is first led through a cooled, continuously operating liquid separator. A first liquid, PSA-rich stream is withdrawn from the liquid separator, as well as a separate residual mixture of gas and vapour. The residual, PSA-containing mixture is led through at least one among a plurality of cooled solid separators to separate solid PSA, which is then periodically liquefied again. A second PSA-rich stream is thus withdrawn from the solid separators. The amount per unit in time ratio between the first and second streams ranges from 1:5 to 2:1. The first stream is led at temperatures from 250 to 300  DEG C through a first dwelling vessel, in which it is subjected under stirring to a preliminary thermal treatment for at least 3 hours. The second, PSA-rich stream is purified by distillation together with the first, thermally pre-treated stream, bypassing the first dwelling vessel.
