Title: Aqueous silane coupling agent solution for use as a sealant primer
Inventor: ANGELINE BARRY D
IPC: C09J5/02
Filed: 1993-06-28
Granted: 2007-02-20
Abstract: An aqueous primer composition for facilitating and promoting good adhesion across an interface between a nonporous substrate and a polymeric coating composition contains from about 0.05 to about 0.3 parts by weight of an amimopropylsilane or a mercaptopropylsilane per 100 parts by weight of water and, to facilitate adhesion under wet conditions, up to about 0.4 parts by weight of a hydrophobic silane per 100 parts by weight of water and aminopropylsilane or mercaptopropylsilane. The primer composition is nontoxic, nonflammable and free or substantially free of any environmentally undesirable volatile organic components. In accordance with a preferred aspect of the invention, the primer composition includes an effective amount of a conventional surfactant sufficient to uniformly wet the surface of the substrate to enable uniform dispersion of the silane coupling agent over the surface. The primer composition is also preferably adjusted to a pH of from about 2.0 to about 5.5 to inhibit condensation or oligomerization of the silane coupling agent and thereby increase the useful shelf-life of the composition.

Title: Methods and apparatus for centering a log and for supplying a log to be centered
Inventor: OJI KOICHI
IPC: B27B31/06
Filed: 1993-12-16
Granted: 1998-11-24
Abstract: Periphery detectors are arranged being juxtaposed closely, along the longitudinal direction of the log which is to be rotated one revolution around avirtual center, thereby a plurality of peripheries of cross sections along the longitudinal direction are detected for the log. The direction of the largest right circular cylinder is determined according to the largest inscribed circles for the peripheries of three cross sections (i.e., the ones adjacent to both the ends of the log and the one in the middle of the log) and the largest right circular cylinder itself is determined according to the peripheries of all cross sections detected. Thus thecenter line of said largest right circular cylinder is adopted as the turning center. The positions of a pair of inclined beams or swing arms are adjusted for canceling the deviation between the turning center and the virtual center. Furthermore, the largest radius of the log rotation around the turning center is determined from all said cross sections detected, and then the planer table is located in the stand in a position where the planer table never invades said largest radius of log rotation.

Abstract: ABSTRACT         A thermoplastic multilayer composite is disclosed.  The composite comprises at least one layer based on a moulding compound of polyamide and at least one layer based on a moulding compound comprising a mixture of polyvinylidene fluoride and polyglutarimide.  The layers are adhesively bonded to one another.          The multilayer composite of the invention has an outstanding resistance to and barrier action against diffusion of chemicals, solvents and fuels.  Since the layers are adhesively bonded to one another, no delamination of the layers occurs on thermal expansion or flexing of the finished part.  The composite can be used in structural parts, particularly in electrical, engineering and automobile industries, where the barrier action of polyvinyl-idene fluoride is to be combined with the good mechanical properties of polyamide.

Abstract: The invention concerns a method for continuously melting down scrap metal, in particular bales of scrap metal containing residual plastic materials, the scrap being fed to a melt-down reactor and the heat necessary to melt the scrap being provided by direct heating from underneath by burners located near the tapping point. Part of the gases produced are passed back, after utilizing the sensible heat and cleaning, as combustion gas into the melt-down reactor and the remainder passed out as output gas. A particular advantage of the invention is that, when melting down scrap metal containing plastic, it avoids the need for large-scale gas-purifying facilities and the pyrolysed materials contained in the starting material are utilized to good effect.

Abstract: A variable force solenoid valve assembly is provided for use in an automatic transmission controller for controllably reducing a fluid inlet pressure to a desired outlet control pressure. The invention includes a solenoid sub-assembly secured to a valve body sub-assembly. The valve body includes a spool valve having three radially extending lands which translate within a valve body central bore in response to movement of an armature sub-assembly provided in the solenoid sub-assembly. Movement of the spool valve generates first and second flow restriction for controllably regulating the reducing of inlet pressure. In addition, the lands and the central bore comprise two differing diameters for improved outlet pressure regulation. Other various improvements in spool valve design are described including a design which enabled a reduction in the overall size of the solenoid sub-assembly.

Title: High efficiency fuel-fired condensing furnace having a compact heat exchanger system
Inventor: LU LIN-TAO
IPC: F24H3/00
Filed: 1995-03-13
Granted: 1997-04-22
Abstract: A tubular recuperative heat exchanger structure is mounted in a housing chamber within a fuel-fired condensing furnace in the vertical flow path of supply air being flowed through the housing by a blower.  The heat exchanger structure comprises a primary heat exchanger defined by a vertically serpentined series of combustor tubes into open inlet ends of which a series of inshot-type fuel burners flow flames and hot combustion gases, and a secondary heat exchanger formed from a horizontally extending series of finned heat exchanger tubes having inlets in flow communication with the outlets of the combustor tubes and outlets in flow communication with the inlet of a draft inducer fan.   The firing rate of the furnace is correlated to the configuration and relative geometries of the primary and secondary heat exchanger tubes in a manner making the overall heat exchanger highly compact and thermally efficient in addition to reducing air blower and draft inducer electrical consumption as well as reducing the operating noise of the furnace.

Granted: 1999-10-19
Abstract: A bumper of synthetic resin for use in an automobile includes a core, and an outer layer covering the core.  The material for forming the core includes a main component produced by pulverizing a recovered bumper which has been formed using a polyolefine-based resin composition modified by an olefinic elastomer and which has a thermosetting synthetic resin coating film on its surface, and a polyethylene added to the main component.  The material for forming the outer layer includes the polyolefin-based resin composition modified by the olefinic elastomer and the polyethylene in a content A2 which is smaller than a content A1 of the polyethylene in the core forming material (A2 < A1).  The impact resistance of the core is enhanced with the addition of the polyethylene, despite the inclusion of the coating film particles.  The outer layer is excellent in heat resisting characteristic, because of a smaller content of the polyethylene.
