Abstract: A sample collection device is provided, which includes a laminate structure which includes at least a first layer and a second layer and a channel sandwiched between the two layers. The channel has an opening at a first end of the laminate structure. The first layer includes a depressible bulb pump disposed distal to the opening of the channel. Depressing and releasing the bulb pump draws a fluid or liquid sample into the channel. The sample collection device can further includes a pad attached to the laminate structure for providing structural support and easy handling. The layers of the sample collection device can be IR neutral so that the device can be used in association with a portable IR or near-IR spectroscopy unit for analyzing the collected sample.

Abstract: A handheld infrared spectroscopy device and method of use. The device is a hand-held spectroscopy device, that may be integral to a mobile phone or smart device such as a smart phone, tablet, personal digital assistant, computer or other device that is portable and capable of performing applications. A liquid sample port internal to the device and in close proximity to the device spectrometer performs infrared spectra analysis on liquid samples, allowing both portability as well as highly sophisticated and specific spectral analysis of liquid samples. The device has wireless communication capability, enabling transmission of data and spectral imagery across the globe.

Abstract: An exhaust system comprises an exhaust driven turbocharger having an outlet and a flanged portion that extends about the outlet, an exhaust treatment device comprising a canister having an inlet cone that includes an integral inlet flange defining an the inlet opening configured to define a seal with the flanged portion that extends about the outlet of the turbocharger and a substrate disposed within the canister through which the exhaust gas flows. An exhaust gas passage, fluidly couples the turbocharger and the exhaust treatment device and allows for the passage of exhaust gas therebetween and a flow modifier comprising a radially inwardly extending wall portion extends from an inner wall of the exhaust gas passage and directs the exhaust gas away from an outer radius of the exhaust gas passage to evenly distribute the exhaust gas across the an inlet face of the substrate.

Abstract: A clamp includes a curved band having an inner surface, an outer surface, a first end, and a second end. The band is characterized by a substantially V-shaped cross-section in a radial plane of the band. The inner surface of the band defines the inside contour of the V-shaped cross-section. The clamp also includes a fastener configured to draw together the first and second ends such that the band may be tightened around adjacent flanges of objects to be clamped together. The inner surface is configured to squeeze the flanges together and clamp the objects. The band includes a reinforcement configured to stiffen the substantially V-shaped cross-section and minimize yielding of the cross-section when the objects are being clamped. An engine assembly that includes a first exhaust component and a second exhaust component having respective first and second flanges being squeezed and clamped together via the clamp is also disclosed.

Abstract: A device and method for temporarily mounting a tool to a member such as an upright board without the need for any prior attachments to the board. A member securing element attached to the tool is secured to the upright board when gripping surfaces engage opposite sides of the board as a result of rotation of the tool brought about by an off-set center of gravity.

Abstract: An improved rail car door closer system is provided wherein the movement of a number of appropriately positioned closer wing plates into contact with a number of open rail car hopper doors, is accomplished with hydraulic cylinders and motors. The system incorporates components that direct both the rotation of the wing closers (around a cylindrical frame so as to position the wing closers in and out of position for door closure), and the translation of the wing closers (along the longitudinal cylindrical frame so as to effect the actual closing of the hopper doors). The system is arranged to close more than one door at a time and in the preferred embodiment includes three simultaneously operated door closer wing structures. The heavy duty cylindrical frame incorporates a number of cylindrical outer segments sized to fit around and on the inner cylindrical frame. The segments are directed to rotate and translate on the inner cylindrical frame.

Abstract: This invention relates to a container (1) for waste material comprising wall portions (4, 6, 7) defining an internal void space and at least one opening (21) through which waste material may be inserted and/or withdrawn from said void space, wherein a roller shutter (22) is provided which is movable from an extended position in which the opening is closed by the roller shutter to a retracted position in which the opening is substantially unobstructed, the roller shutter being wound onto a barrel arrangement (26) as it is retracted, wherein in the retracted position that portion of the roller shutter wound onto the barrel arrangement is located within the internal void space of the container defined by the wall portions.

Abstract: There is provided a housing for a flow conditioner. The housing comprises a body having first and second pipe connections, a flow passage between the pipe connections, a carrier receiving cavity within the flow passage, and an opening corresponding to the carrier receiving cavity. A plate carrier has a sealing portion and a flow conditioner carrying portion. The sealing portion has a sealing surface for sealing the opening corresponding to the carrier receiving cavity, and the flow conditioner carrying portion depends from the sealing portion. The flow conditioner carrying portion is sized to be inserted through the opening and into the carrier receiving cavity, and has a plurality of set screw receiving apertures or a retaining lip for securing the flow conditioner. There is a connector for securing the plate carrier within the body such that the sealing surface seals against the body.

Abstract: A track mounted system for closing rail car doors that enables the simultaneous closing of multiple car doors. After hopper car contents such as aggregate or coal are unloaded, the doors are closed in pairs by semi-automated door closing arms that are positioned on the track and are operated by hydraulic cylinders, pneumatic cylinders, or electric motors. The closing arms may be added in pairs depending on the number of doors. Hydraulic cylinders with a differential bell crank can be used to activate the closer arm assemblies. Closer arms can be mounted side by side on the inside or outside of the track or separately inside and outside of the track. Automatic slack adjustment assemblies may be integrated into the closer arm connections to allow for off set door spacing. Individual hydraulic cylinders may be used with each closer arm in an alternate embodiment.
