Abstract: A method for determining the positional laydown accuracy of an automated lamination machine during fabrication of a multiple layered part is described. The method includes measuring a position of a placement head of the lamination machine in a coordinate system, determining a location of a ply edge with respect to the placement head, transforming the location of the ply edge into the coordinate system, based on the measured head position, transforming the location of the ply edge from the coordinate system into a second coordinate system that is associated with the part being fabricated, and comparing actual ply edge location in the second coordinate system to an expected ply edge location defined in the second coordinate system, the second coordinate system associated with the part being fabricated, to determine the laydown accuracy of the machine.

Abstract: A transportable utility carrier apparatus for coupling to a transport vehicle, including an upper frame, a recessed platform connected to the upper frame, a wheeled base, a lift system interposed between the base and the upper frame for moving the wheeled base relative to the platform between a transport position and a freestanding position, a square hitch tube connected to the upper frame, and a rollered receiver hitch mountable to the transport vehicle. The wheels are spaced from the ground in the transport position. The square hitch tube is receivable within the rollered receiver hitch and the rollered receiver hitch eases insertion of the square hitch tube thereinto to prevent binding on unleveled ground.

Abstract: A trailer and trailer cage for produce in which the front, rear and sides of the cage are flexibly connected to one another. The invention also relates to a mechanism for tensioning a side gate of the cage.

Abstract: In the field of vacuum-assist-resin-transfer-mold (VARTM) processing, a new system is provided to lower production times and to create a high permeability mold cavity with reduced directionality to yield an optimum flow-front. The system comprises the use of a high permeability layer to evacuate air from the mold cavity and may include a reusable port-runner device for introduction of resin into the fiber mat. In the preferred embodiment, the high permeability layer is a “felt-like” material constructed of synthetic fibers, and the reusable port device is a flat, modular unit. In another embodiment, the high permeability layer is a fluid-impervious material with sporadic protrusions, and the reusable port-runner device is a flexible, silicone unit. Other embodiments are comprised of any combination thereof. Each embodiment is designed to minimize set-up times and to create a mold cavity with a low resistance to fluid flow through the application of pressure differentials.

Abstract: An apparatus for measuring spectral absorbance using unique optical modulator capable of temporally changing the spectral wavelength proportion of the light source to produce spectral absorbance data of a sample having: a) a light source able to produce light in the desired wavelength region to be measured for spectral absorbance. b) optical modulator capable of temporally changing the spectral wavelength proportion of the light source. c) sample holder capable of introducing the sample into the light path and d) photosensor for determining the total light intensity after passing through the sample.

Abstract: The present invention generally relates to the determination of photoluminescence of samples. More specifically, the present invention is directed to a method particularly adapted to samples which are flowing liquids. The method and apparatus are useful for measuring photoluminescing species such as those found in liquid chromatography and capillary electrophoresis.

Abstract: This invention relates to an apparatus for pressurizing a fluid and delivering a gas comprising a pump, an accumulator and a heater such that the pump pressurizes a quantity fluid received from a fluid store and delivers that pressurized fluid to an accumulator. The accumulator then delivers a quantity of the pressurized fluid to a heater that, in turn, warms the fluid to a gas within a specified temperature and pressure range to be delivered to the end user as required. The invention further relates to a method of delivering a gas at a desired pressure and temperature wherein a quantity of fluid is received, pressurized and stored as a fluid in an accumulator storage vessel at a desired pressure. The fluid is then delivered from the accumulator to a heater where it is warmed and delivered to the end user as a gas at specified temperature and pressure.

Abstract: A method and apparatus for controlling the equivalence ratio in an internal combustion engine to improve catalytic converter performance including varying an equivalence ratio setpoint between a rich and a lean state periodically, and introducing a fuel enrichment pulse to the equivalence ratio that sweeps the equivalence ratio across stoichiometry.

Abstract: A raisable and lowerable platform that houses a removable charcoal or gas grill and a removable cooler chest, with a storage compartment between the two, a telescoping flagpole mounted to the platform, and a fold down table attached on both ends of the platform to provide more cooking area.

Abstract: An adjustable safety bracket for use in roof construction provides a support for a safety barricade to be erected along the edge of the roof. The bracket assembly includes an attachment member which engages the free end of a roof support bracket, such as a roof joist, and a support member which is pivotally connected to the attachment member at an outer end thereof. The attachment member includes a channel portion which engages the free end of the roof support member and further includes a yoke in which the support member is pivotally supported. The support member includes a stop surface aligned with the channel portion such that when installed, the stop surface faces the free end of the roof support member and the free end limits the rotation of the support member within the attachment member.
