Abstract:
A method for producing a multilayer molded article in which an skin material having nap on the outer surface thereof is integrally molded with a substrate of a synthetic resin, using a mold comprising a pair of male and female mold halves. In this method, after the fabric skin material and the molten resin are clamped in the mold and primary cooling is carried out, the mold is opened halfway to form a predetermined gap between the mold halves, and the molten synthetic resin undergoes secondary cooling and hardens while the mold is held in the half-open state. In the present invention, the time period for the operation to open the mold halfway is set at one second or less. By limiting the half-opening operation time period to the short period of one second or less, recovery of the nap is reliably achieved without the nap tending to stay flattened. Moreover, because the transition from the primary cooling step to the secondary cooling step occurs in a short period of time, problems such as inadequate cooling of the molten synthetic resin do not occur.
Abstract:
A monolithic self-constrained green body tape for use in low temperature ceramic co-firing is provided. The tape contains at least two layers: one low temperature ceramic layer containing particles of a glass, a ceramic, and an organic binder, and a self-constraining layer containing a refractory ceramic and a wetting agent for the glass in the first layer. When the tape is fired at a sintering temperature of the low temperature ceramic layer, densification occurs in the z (thickness) direction, but essentially no shrinkage (less than about 1%) occurs in the x-y planes. A method for forming a multilayer green body tape using simultaneous wet on wet ceramic slurry deposition is also provided. A dense, monolithic, low temperature, co-fired, self-constrained, multicomponent structure is also provided. The structure contains at least two multilayer ceramic substrates having electronic circuit components mounted thereon or therein. Each multilayer ceramic substrate contains at least two layers with one being a self-constraining layer.
Abstract:
The foam and cemitious waterfalls that are produced in the invention process are lighter than natural stone and have the appearance of natural stone. The cost of creating waterfalls in this way saves time and money. The process consists of carving 1-lb. density foam into any waterfall shape, adding irregular foam shapes to outside of feature with polyurethane based glue. A self-adhesive mesh is applied; rubber liner installed in mote and the final process is a cemitious coating with color pigment is applied to mesh. The end result is a rock like water feature.
Abstract:
Provided herein is a molded vanity top with a surface layer and a composite backing. The backing is made from a polyurethane resin and a filler, which may be any material compatible with the polyurethane resin. The filler is preferably sand and makes-up up to about 85% by weight of the backing. The disclosed vanity tops have the substantial weight and solid sound preferred by consumers, yet are often lighter and stronger than cultured marble vanity tops. Also provided herein is a method of manufacturing a molded vanity top. The interior of a mold is coated with a surface layer. The mold is then filled with a composite backing material made from a polyurethane resin and a filler. After curing, the vanity top is demolded and finished.
Abstract:
The mold-in fastening member comprises a substrate having engaging elements on a top surface thereof and a foamed synthetic resin layer bonded to a rear surface of the substrate. The foamed synthetic resin layer has overhanging marginal portions or sealing portions extending outwardly beyond at least both lateral edges of the substrate. The foamed synthetic resin layer has a thickness of 1 to 10 mm and an initial compressive modulus of 0.02 to 1.0 MPa. The mold-in fastening member surely prevents a molding resin from entering through gaps between the mold-in fastening member and a recess formed in a mold.
Abstract:
A method for making a poured-in-place concrete building having a plurality of rooms includes assembling an outer form around a periphery of a floor and positioning a plurality of unitary room forms within the periphery of the floor. Each unitary room form may include a plurality of rigid panels connected together along respective adjacent sides thereof defining a closed shape with an open bottom and an open top and having a draft thereto to facilitate removal as a unit. The method may also include pouring concrete between the outer form and adjacent unitary room forms and between adjacent unitary room forms to provide outer concrete walls and interior concrete walls, respectively, to define the rooms. Further, each of the unitary room forms may be removed as a unit from adjacent concrete walls, the outer form may be disassembled, and a roof may be provided over the rooms.

A tongue set is provided on the top surface of the block and a groove in the bottom surface of the block. The tongue set includes a rear-facing surface set that includes first and second curved sections. A block form for forming retaining wall blocks is also provided. A face form for placement on the bottom surface of a block form is also provided. A method of molding retaining wall blocks with a form having hinged doors is also provided. A method of using a face form for forming two blocks of reversed front surface ornamentation is also provided.
Abstract:
A poured-in-place concrete building having a plurality of rooms includes a floor, a plurality of poured-in-place outer concrete walls around a periphery of the concrete floor, and a plurality of poured-in-place interior concrete walls within the outer concrete walls defining the rooms. Each of the outer concrete walls may have a progressively decreasing thickness from a lower end to an upper end thereof. Further, each interior concrete wall may also have a progressively decreasing thickness from a lower end to an upper end thereof. The building may also include a roof adjacent upper ends of the outer and inner concrete walls and covering the rooms.
Abstract:
A method for fabricating a disc drive load/unload ramp incorporates a disc drive compatible lubricant as the mold releasing agent. A mold having a load/unload ramp cavity is sprayed with a predetermined amount of disc drive compatible lubricant so that the finished load/unload ramp exhibits a predetermined thickness of lubricant. Alternatively, a known amount of disc drive compatible lubricant is combined with the load/unload ramp polymer during the melting stage of the molding process to yield a load/unload ramp exhibiting a predetermined thickness of lubricant. In either case, the lubrication of the load/unload ramp is integrated into the fabrication process in order to obtain a one step finished pre-lubricated product.
Abstract:
A foundation framework for structures in a reinforced setting material includes a foundation raft with a form having a plurality of modular panels and angular reinforcements for joining at least two faces of at least one right-angle dihedral formed by faces of the modular panels. A layout and positioning template is disposed on top of the form of the foundation raft for correctly dimensioning, positioning, and fitting walls, installations and reinforcements in the foundation raft. Adjustment legs for centering the layout and positioning template are provided, as well as self-centering clamps and a stabilizer having security pins and an anchorage mechanism for securing the form to a support surface.
