  • Patent number: 10554077
    Abstract: A process for detecting statistically significant changes in energy consumption patterns by monitoring for changes in the parameters to a parametric energy model. Two parametric models of energy consumption are created: the first being a model providing an initial base line of energy consumption, the second being a test model to be compared to the initial base model. Statistically significant changes are detected by using a difference score that compares the parameters of two models along with the uncertainties of each parameter to determine whether the differences in the parameters of each model indicate a statistically significant deviation in the energy consumption pattern.

  • Patent number: 10296554
    Abstract: Optical metrology is used to calibrate the plane-of-incidence (POI) azimuth error by determining and correcting an azimuth angle offset. The azimuth angle offset may be determined by measuring at least a partial Mueller matrix from a calibration grating on a sample held on a stage for a plurality of POI azimuth angles. An axis of symmetry is determined for a curve describing a value of a Mueller matrix element with respect to POI azimuth angle, for each desired wavelength and each desired Mueller matrix element. The axis of symmetry may then be used to determine the azimuth angle offset, e.g., by determining a mean, median or average of all, or a filtered subset, of the axes of symmetry. If desired, an axis of symmetry may be determined for data sets other than Mueller matrix elements, such as Fourier coefficients of measured signals.

  • Patent number: 8691128
    Abstract: To provide an expansion injection molding process, which is freed from the occurrence of swirl marks on the surface of a molded article and by which foamed injection moldings having good appearance can be produced in a short molding cycle and at a low cost; and a mold for expansion injection molding. A movable mold 2 is moved toward a fixed mold 1, whereby a sealing member 6 set on at least one of a pair of facing surfaces of the mold 1 and mold 2 in the outside of a cavity is brought into contact with the other of the facing surfaces or a sealing member 6 set thereon to make the cavity 3 gas-sealed state. While keeping the gas-sealed state, the movable mold 2 is further moved toward the fixed mold 1 with the sealing member 6 compressed, whereby the volume of the cavity 3 is decreased to enhance the pressure in the cavity 3 to a level exceeding the atmospheric pressure. Then, a thermoplastic resin is injected into the cavity 3 of an enhanced pressure.

  • Patent number: 8597561
    Abstract: An object of the present invention is to provide a method for producing a pneumatic tire, that does not cause an air-in phenomenon between an inner liner and an insulation or carcass by preventing adhesion of an inner liner to a bladder. The method for producing a pneumatic tire according to the present invention includes the following steps. A green tire using, as an inner liner, a polymer composition in which a polymer component contains 100 to 60% by mass of a styrene-isobutylene-styrene triblock copolymer and 0 to 40% by mass of a polyamide-based polymer that contains polyamide in the molecular chain and has a Shore D hardness of 70 or less is prepared. The green tire is mounted in a mold and vulcanized while being pressurized by a bladder. The resultant vulcanized tire is cooled at 10 to 120° C. for 10 to 300 seconds.

  • Patent number: 8557160
    Abstract: A process, and related structure, uses conventional palletized compositions to form the elements of a non-textile fabric by coining a single pellet or briquette of a polymer into an individual element in a single forming step. The steps of the process generally include: a) positioning a pellet in or adjacent to a mold cavity, and b) forcing the pellet into contact with the mold surfaces of the mold cavity to plastically deform the pellet to the shape of the mold cavity. The forcing step preferably uses an energy and speed where the pellet superplastically deforms to substantially fill the mold cavity. This process is repeated with the elements being formed in the appropriate order to form a non-textile fabric. The elements thus formed can have a variety of shapes, and can form base units for the formation of the non-textile fabric of two, three or more elements.

  • Patent number: 8545747
    Abstract: A method of forming a part with a feature having a die-locked geometry is disclosed herein. A molding tool used in the method includes at least one die having a cavity defined in a surface thereof, and a protrusion formed in the cavity. The method includes disposing a shape memory polymer insert on the protrusion, where the shape memory polymer insert has i) the die-locked geometry as its temporary shape, and ii) a geometry that is removable from the die-locked geometry as its permanent shape. A material is established in the cavity such that at least a portion of the material conforms to the die-locked geometry, thereby forming the part having the feature with the at least one die-locked geometry.

  • Publication number: 20130241100
    Abstract: A method of forming a composite article (22) comprises the steps of providing a tool (26) having a mold surface (24), providing a preform (62), and disposing the preform (62) on the mold surface (24). The method further comprises the steps of heating the mold surface (24) within a first period of time (Tt1), applying pressure to the preform (62) within a first period of time, and maintaining temperature of the mold surface (24) for a second period of time (Tt2). The method further comprises the steps of maintaining pressure for a second period of time, reducing pressure on the composite article (22), cooling the mold surface (24) within a third period of time (Tt3), and removing the composite article (22) from the mold surface (24). The total of Tt1+Tt2+Tt3 is generally no greater than about 30 minutes. A thermal system (20) comprising a heater-subsystem, and optionally, a chiller-subsystem, can be used to heat and cool the mold surface (24).

  • Publication number: 20130221580
    Abstract: The present application relates to a method and system that can be utilized to manufacturing composite structures in a closed cavity mold. The tool system includes a closed cavity tool with spring members that when in compression apply pressure to a preform located within the closed cavity mold. During a curing cycle, the spring members provide substantially constant pressure to the preform, thereby preventing voids and porosity in the cured composite structure. Further, the substantially constant pressure, provided by the spring members, acts to more effectively conform the preform to the geometry defined by a void in the closed cavity mold during the curing cycle.

  • Publication number: 20130187296
    Abstract: The present invention is related to a method for producing a resin compact containing an epoxy resin, a curing agent, a curing accelerator and an inorganic filler. The method includes a kneading and crushing process for preparing a first powder material obtained by mixing, heat-melting, kneading and crushing a first component containing the epoxy resin and the curing agent and the inorganic filler, but not containing the curing accelerator; a pulverizing process for preparing a second powder material obtained by pulverizing a second component containing the curing accelerator; a mixing process for preparing a resin composition by dispersing and mixing the first powder material and the second powder material; and a molding process for obtaining the resin compact by compression-molding the resin composition. This makes it possible to obtain a resin compact (particularly, a resin compact for encapsulation) having superior long term storage stability at room temperature, good curable property and fluidity.
