Abstract:
An alarm and locking device for deterring theft of removable vehicle rooftops. An alarm is sounded if an unauthorized attempt to remove a rooftop is made, while successful removal of the rooftop is prevented by a locking mechanism.
Abstract:
Electroporation systems and methods are provided that include a processing assembly including a housing, a lid rotationally connectable to the housing, an opening in a top surface of the housing, an electroporation chamber below the opening in the housing, wherein the electroporation chamber comprises (i) two or more electrodes coated with an electrically conductive, non-cytotoxic material, and (ii) a gasket forming the shape of the electroporation chamber and defining the volume of one or more wells within the electroporation chamber. The system may include a docking station, the docking station comprising, a housing, a port in the housing configured to receive the processing assembly, a lid connected to the housing, one or more contacts configured to connect the docking station to an electroporation system housing.
Abstract:
The enumeration of cells in fluids by flow cytometry is widely used across many disciplines such as assessment of leukocyte subsets in different bodily fluids or of bacterial contamination in environmental samples, food products and bodily fluids. For many applications the cost, size and complexity of the instruments prevents wider use, for example, CD4 analysis in HIV monitoring in resource-poor countries. The novel device, methods and algorithms disclosed herein largely overcome these limitations. Briefly, all cells in a biological sample are fluorescently labeled, but only the target cells are also magnetically labeled. In addition, non-magnetically labeled cells are imaged for viability in a modified slide configuration. The labeled sample, in a chamber or cuvet, is placed between two wedge-shaped magnets to selectively move the magnetically labeled cells to the observation surface of the cuvet. An LED illuminates the cells and a CCD camera captures the images of the fluorescent light emitted by the target cells. Image analysis performed with a novel algorithm provides a count of the cells on the surface that can be related to the target cell concentration of the original sample. The compact cytometer system provides a rugged, affordable and easy-to-use technique, which can be used in remote locations.
Abstract:
A process for preparing a naphtha reforming catalyst has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid (EDTA). The aqueous solution of the chelating ligand and a tin compound is used to impregnate a support, e.g., alumina extrudates. A platinum-group metal is also an essential component of the catalyst. Rhenium may also be a component. A reforming process using the catalyst has enhanced yield, activity, and stability for conversion of naphtha into valuable gasoline and aromatic products.

Abstract:
The present invention provides a system for imaging circulating tumor cells from blood after enrichment. The system is designed to provide optimum use in a clinical laboratory setting with minimum laboratory bench top space. Operator intervention is minimized compared to other analytical methodologies. The system is useful in the enumeration and identification of target cells in a sample specimen for screening and detection of early stage pre-metastatic cancer, monitoring for disease remission in response to therapy and selection of more effective dose regimens or alternative therapies for individual patients.
Abstract:
A catalyst, and a process for using the catalyst, that effectively converts and transalkylates indane and C10 and heavier polycyclic aromatics into C8 aromatics is herein disclosed. The catalyst comprises a solid-acid support such as mordenite plus a metal component such as rhenium. The catalyst provides excellent conversion of such heavy aromatic species as naphthalene, which is also observed by a decrease in the ending-boiling-point of a hydrocarbon stream passed over the catalyst. The same catalyst is also effective for transalkylation of lighter aromatics, thus yielding a valuable xylenes product stream out of the process.
Abstract:
Sulfur oxides are removed from a gas by an absorbent comprising at least one inorganic oxide selected from the group consisting of the oxides of aluminum, magnesium, zinc, titanium, and calcium in association with at least one free or combined rare earth metal selected from the group consisting of lanthanum, cerium, praseodymium, samarium, and dysprosium, wherein the ratio by weight of inorganic oxide or oxides to rare earth metal or metals is from about 0.1 to about 30,000. Absorbed sulfur oxides are recovered as a sulfur-containing gas comprising hydrogen sulfide by contacting the spent absorbent with a hydrocarbon in the presence of a hydrocarbon cracking catalyst at a temperature from about 375.degree. to about 900.degree. C. The absorbent can be circulated through a fluidized catalytic cracking process together with the hydrocarbon cracking catalyst to reduce sulfur oxide emissions from the regeneration zone.
