  • Patent number: 6841231
    Abstract: Fibrous composite articles and method of manufacturing the same are disclosed. The preferred fibrous materials have average fiber lengths of less than about 2 millimeters, and are obtained from industrial hemp hurd, kenaf hurd, and/or the culms of various species of vegetable bamboo. The fibers are combined with a binder resin and, optionally, a sizing agent to form a mat that is consolidated under heat and pressure to form the composite articles. The formed articles exhibit strength and durability characteristics at least roughly equivalent, if not superior, to those of conventional wood-based fibrous composite articles.

  • Patent number: 6823893
    Abstract: A non-return valve has a valve housing with a flow channel having a vertical channel section, an inlet aperture, an outlet aperture and a blocking device closing the flow channel. The blocking device comprises a valve seat surrounding the outlet aperture and a valve disc movable between an open position and a closed position. The valve disc is guided in the valve housing via a guide surface on its outer circumference, and comprises flow apertures radially outside its sealing surface. The valve disc possesses a diameter that becomes smaller towards the valve seat, forming an inclined external surface. Flow apertures start from the inclined external surface and converge in the direction facing away from the sealing surface, and are disposed in a uniform distribution over the circumference of the valve disc.

  • Patent number: 6810850
    Abstract: A controlled exhaust brake for an engine comprises an exhaust restrictor located in an exhaust system downstream of an exhaust manifold of an engine. An actuator operably associated with the restrictor adjusts the restrictor. A pressure sensor operably associated with the exhaust manifold senses pressure in the exhaust manifold. A controller determines a set pressure in the exhaust manifold correlated with speed of the engine. The controller is in communication with the pressure sensor and the actuator, and causes adjustment of the restrictor in order to achieve and maintain the set pressure in the exhaust manifold.

The constant-current output drive circuit unit may include a drive source circuit segment and a drive sink circuit segment that function as a complementary constant-current circuit unit. Preferably, the drive source circuit segment and the drive sink circuit segment are connected to respective constant-current output bias circuit units.

  • Patent number: 6811590
    Abstract: A gas concentrating method and apparatus is provided in which equalization is accomplished below two sieve beds, to thereby save compression energy, to reduce exit noise, and to obtain a gas whose gas purity with respect to an amount of flow has been enhanced. The gas concentrating method makes two sieve beds communicate with each other at their bottoms when a pressure difference between a pressurized pressure and a decompressed pressure is maximized in the multi-bed type sieve beds which alternately operate between pressurization and decompression, to equalize an internal pressure in the sieve beds. The gas concentrating apparatus includes a compressor (50), sieve beds (60-1, 60-2), solenoid valves (40-1, 40-2), an orifice (90), check valves (90-1, 90-2), a storage tank (100), a pressure controller (70), a flow meter (80), a controller (110), and a muffler (20).

  • Patent number: 6808080
    Abstract: An apparatus designed to automatically latch and unlatch the lid of a container. The apparatus includes a weight pivotally mounted on the side of the container for movement between first and second positions. The weight is positively connected to a latch by a connecting rod, and as the weight pivots between first and second positions, it moves the latch between latching and unlatching positions. Tipping the container causes the weight to shift thus the container is unlatched only when it is being dumped. A method for operating the latch is also disclosed.

  • Patent number: 6810351
    Abstract: A position detector includes a position indicator. Transmission/reception of electromagnetic waves relative to the position indicator is performed at least twice while the same loop coil is being selected. With a counter circuit and a switch circuit, a phase difference less than or equal to one cycle of a resonant frequency fO is added to a signal in each transmission/reception. The phase of a reception signal generated at the loop coil is adjusted, and the phase-adjusted signal is used as a detection clock by a synchronous detector circuit to perform synchronous detection. By computing the average or the sum of the results, external noise in the reception signals is cancelled out.

  • Patent number: 6801192
    Abstract: In an input pen having a pen-shaped casing, a ferrite core with a coil wound thereon and a ferrite chip are placed opposed to each other via an O-ring. The ferrite chip has a projection. When the input pen is operated, the projection and the ferrite core are moved closer together. When the ferrite chip is moved closer to the ferrite core during operation, the projection is placed substantially close to the ferrite core. Therefore, high responsivity is ensured without moving the ferrite chip into the coil, and there is no need to form an opening or a cavity in the ferrite core.

  • Patent number: 6798284
    Abstract: A reference circuit having a variable-impedance function for reducing current consumption is provided. By switching an output impedance of the reference circuit so that the output impedance is large when transmitting a high-frequency signal to a sensor coil, and the output impedance is small when receiving a response signal from the sensor coil, current consumption is reduced. The reference circuit includes a loop gain adjusting circuit having a switch for switching a gain. The magnitude of the output impedance of the reference circuit is switched by opening and closing the switch to switch the gain.

  • Patent number: 6797216
    Abstract: A method of making polymeric particulates wherein polymeric scrap material, virgin polymeric material and mixtures thereof are supplied to intermeshing extruder screws which are rotated to transport the polymeric material along their length and subject the polymeric material to solid state shear pulverization and in-situ polymer compatibilization, if two or more incompatible polymers are present. Uniform pulverized particulates are produced without addition of a compatibilizing agent. The pulverized particulates are directly melt processable (as powder feedstock) and surprisingly yield a substantially homogeneous light color product. The pulverized particulates also can be more intimately mixed than mixtures which are provided by only melt mixing, and can be melt processed without a significant delay in achieving phase inversion. The pulverized particulates also provide a stable microstructure.

  • Patent number: 6780280
    Abstract: A pressing cushion (1) for use in laminating presses has a textile support (2) with threads (3, 4, 5), at least some of which constitute thermally conductive threads (3, 4, 5) that bring about, either directly or by contact with other thermally conductive threads (3, 4, 5), a thermal transfer from one outer side to the other outer side of the pressing cushion (1). The support (2) includes a cushion layer (7) made of a flexible rubber material, wherein the thickness of the cushion layer (7) is less than that of the support (2). The cushion layer (7) is embedded into the support (2) in such a way that thermally conductive threads (4, 5) protrude beyond the cushion layer (7) on both outer sides of the pressing cushion (1).
