  • Patent number: 7556007
    Abstract: In a method for forming an injection molded manifold, the portion of the mold that forms a septum is modified to provide a substantially thicker septum, preferably about 8.5 mm or greater. In the molding operation, one or more removable slides are inserted through this region of the mold, each slide being preferably about 2.5 mm thick and about 30 mm wide. The septum is cast around the slides which are then withdrawn from the septum after the polymer composite is set, resulting in a septum that is substantially thicker than a prior art septum, comprising first and second plates, each about 3 mm thick, and a plurality of open core voids about 2.5 mm high and about 30 mm wide between the plates. The improved septum is stiffer than a single 4 mm thick prior art septum, has a higher natural frequency, and improves suppression of engine noise.

  • Publication number: 20090096131
    Abstract: A method of forming a polymeric component (41, 50, 51, 55) on a body (100, 200, 400) provides an open mould (501, 502) having an inner surface (503, 504). The mould is placed onto a surface (401) of the body (400 so that a closed cavity (505) is formed by the inner mould surface and the body surface. A fluid polymeric material is introduced into the closed cavity which is caused to harden to form the polymeric component as a casting on the body.

  • Publication number: 20090092341
    Abstract: The present invention is generally directed toward a product, such as a trash bag or other flexible, walled container, that is manufactured using a tubular film of biodegradable material. The product is a biodegradable bag being manufactured by folding at least one time along a longitudinal line, and sealing together the plurality of layers of the folded tubular film of biodegradable material. The tubular film is also provided with a first and second transverse cut. The first transverse cut is adjacent to the seal on a first side of the seal to define the bottom of the bag. The second transverse cut is spaced away from the seal on a second side of the seal to define the upper opening of the bag.

  • Publication number: 20090072429
    Abstract: A method for manufacturing rigid panels made of a composite material requires a caul sheet having a smooth surface that is formed with a plurality of grooves. A first layer of the composite material is laid on the caul sheet, and is cut to create flaps that extend into the respective grooves. Strips of composite material are then placed along the edges of the groove to extend and overlap each other in the groove. Next, a unidirectional ply is placed along the length of the groove, and this combination is then covered with a second layer of the composite material. Together, the combination of the first and second layers, the strips and the unidirectional ply are co-cured to create a rigid panel with integral stiffening members.

  • Publication number: 20090072448
    Abstract: A process of continuously producing a more isotropic, electrically conductive composite composition is provided. The process comprises: (a) continuously supplying a compressible mixture comprising exfoliated graphite worms and a binder or matrix material, wherein the binder or matrix material is in an amount of between 3% and 60% by weight based on the total weight of the mixture; (b) continuously compressing the compressible mixture at a pressure within the range of from about 5 psi or 0.035 MPa to about 50,000 psi or 350 MPa in at least a first direction into a cohered graphite composite compact; and (c) continuously compressing the composite compact in a second direction, different from the first direction, to form the composite composition in a sheet or plate form. The process leads to composite plates with exceptionally high thickness-direction electrical conductivity.

  • Publication number: 20090072437
    Abstract: A method of casting a cover layer about a golf ball core utilizing a single cavity mold that moves on a continuous conveyor, and the cover layers are cast without any “stop and go” or batch methods being involved. The continuous motion conveyor system is a closed loop system that provides for the automatic pre-heating of top and bottom mold halves and the depositing of a core into the bottom mold halve after a layer material such as urethane has been dispensed into the molds by an articulating module comprising of a plurality of dispensing nozzles. The nozzles translate in a tangential motion with the moving conveyor and dispense the cover material without any stoppage of the conveyor line. The method then assembles the mold halves into a single cavity mold without the use of bolts, but only employing clamping pins that use spring force for compression, and releasable retainers to lock the mold for the curing stage, and then unlocking he mold for the disassembling and product removal.

  • Patent number: 7501035
    Abstract: A method of manufacturing a replica diffraction grating includes the steps of: forming a metal thin film on a grating surface of a master diffraction grating, adhering a replica substrate to the metal thin film via an adhesive, and removing the replica substrate so that the metal thin film in a reverse state is adhered on the replica substrate. In the method, before forming the metal thin film on the grating surface of the master diffraction grating, the grating surface is coated with a fluorine surface treating agent as a release agent. Then, the metal thin film is formed with vacuum vapor deposition.
