Abstract: A wheel cleaning assembly which has a rotatable carousel which supports a number of wheel raising and lowering arms. The carousel turns in time sectors and has a delay period after the carousel has turned one sector. For instance, at one station a wheel is lowered into a tank and retained in a lowered position for a time period after which it is raised and the carousel turns one sector. Each position of delay is a wheel cleaning station and wheel-cleaning stations, including a hot water soak, a spinning and spraying station, a cold water spray and a spinning and air drying station are included.

Abstract: An apparatus for quenching in hydroprocessing of a hydrocarbon feed stream, which provides a substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed which substantially fills the entire volume of a reactor vessel. Catalyst are selected to be essentially the same density, shape and size at a design feed rate of liquids and gas to prevent ebullation of the packed catalyst bed at the design feed rates. The liquid and gas components of the hydrocarbon feed stream flow into the bed of catalyst and a quenching medium, which is preferably a liquid, is injected into the bed of catalyst. Injection of a liquid quench reduces the gas component of the hydrocarbon feed stream while simultaneously increasing the residence time and reducing the liquid velocity of the liquid component of the hydrocarbon feed stream within the substantially packed bed of catalyst.

Abstract: The present invention relates to a process for preparing the zeolite ZSM-11 using 3,5-dimethylpiperidinium compounds as an organic templating agent, and to the zeolite ZSM-11 in the pure phase form.

Abstract: Section mills have been invented that have one or more blades whose tops are rotatably extendable outward from a mill body as bottoms of the blade(s) rotate about a fixed point, the blade bottoms rotatably secured to the mill body so that, in response to a downwardly moving wash tube contacting the blades, tops of the blades move out from the mill body. In one aspect the blades have a milling surface which is of such an outward extent and which is parallel to a central longitudinal axis of the mill body when the blades are fully extended so that the blades achieve "full sweep" milling.

Abstract: A multi-axis seat test machine for use with seats is disclosed. The test machine includes a loading element and a seat mount. A selectively actuable fore-aft displacement mechanism is disposed between the loading element and the seat mount and operably displaces one of the seat mount and the loading element relative to the other in the fore-aft direction. A selectively actuable lateral displacement mechanism is disposed between the loading frame and the seat mount and operably displaces one of the seat mount and the loading frame relative to the other in a lateral direction. An engaging member simulates, at least in part, a shape of a human posterior for engagement with the seat. The loading element operably biases the engaging member against the seat in a substantially vertical direction with a predetermined vertical load.

The assembly also includes a pair of solid circular metal plates positioned to sandwich the piezoelectric ceramic crystal between them, wherein each of the metal plates comprises: (i) an outer rim circling a concave portion formed in a first surface of the metal plate, the first surface oriented toward the piezoelectric ceramic crystal; and (ii) an epoxy wicking barrier formed in the first surface, adjacent to the outer rim. The assembly also includes an epoxy adhesive interposed between the metal plates and the piezoelectric ceramic crystal, wherein the outer rim of each plate is bonded to the piezoelectric ceramic crystal by the epoxy adhesive, the pair of plates thus forming a cavity between them. The assembly also includes a flexing stop attached to each first surface.

Abstract: An optical waveguide sensor arrangement for sensing at least one physical parameter is provided. This arrangement comprises an optical waveguide having guided modes, lossy non-guided modes, and a long period grating coupling the guided modes to the lossy non-guided modes wherein the long period grating produces a wavelength transmission spectrum functionally dependent on the physical parameter sensed. A source means provides light to the optical waveguide sensor and an optoelectronic detector, which is positioned in an operable relationship to the optical waveguide sensor, detects light transmitted through the optical waveguide sensor. Lastly, a processing means is attached to the optoelectronic detector for correlating the wavelength transmission spectrum with a numerical value for the physical parameter sensed. The physical parameters sensed by the optical waveguide sensor include: temperature, strain, shape, refractive index and corrosion.
