11,444. Ramm, P. J., and Behrendt, F. May 20. Self-closing valves. -A self-closing tap or valve adapted for service pipes, and for flushing urinals &c., is shown in Fig. 1. The casing a has an inlet a , and is closed by a cap b having an outlet d and a seat c for the valve g, which is closed by the water pressure assisted by a spring h. The valve spindle i carries an operating-handle k.
Abstract:
A method for improving the reliability and/or accuracy of physical measurements obtained from array hybridization studies performed on an array having a large number of genomic samples uses a small number of replicates insufficient for making precise and valid statistical inferences. This is overcome by estimating an error in measurement of a sample by averaging errors obtained when measuring the large number of samples or a subset of the large number of samples. The estimated sample error is utilized as a standard for accepting or rejecting the measurement of the respective sample. The samples may be independent or dependant in that correlated across two or more conditions.
Abstract:
The invention relates to a method for producing a titanium phosphide layer, wherein initially a carrier is placed in a reactor. Subsequently, a TiN layer is deposited on the carrier by adding TiCl4 and NH3 in the reactor. The TiN layer is tempered by adding PH3 in the reactor immediately after the TiN layer has deposited in order to form the titanium monophosphide layer on the TiN layer.
Abstract:
Ein Verfahren zur Herstellung eines dreidimensionalen elektronischen Systems umfasst: ein Bereitstellen einer ersten integrierten Schaltungsstruktur in einem ersten Substrat (110), wobei die erste integrierte Schaltungsstruktur eine Kontaktfläche (150) an einer ersten Hauptseite (117) des ersten Substrats (110) aufweist; ein Bereitstellen eines zweiten Substrats (210) mit einer Hauptseite (215); ein Bilden eines vertikalen Kontaktbereichs (240) in dem zweiten Substrat (210). Daran anschließend umfasst das Verfahren ein Bilden einer Halbleiterschicht (212) auf der Hauptseite (215) des zweiten Substrats (210); ein Bilden eines Halbleiterbauelements einer zweiten integrierten Schaltungsstruktur in dem zweiten Substrat (210) mit der Halbleiterschicht (212); ein Entfernen von Substratmaterial von einer der Hauptseite (215) gegenüberliegenden Seite (217) des zweiten Substrats (210), so dass der vertikale Kontaktbereich (240) an der gegenüberliegenden Seite (217) elektrisch freigelegt wird; ein aufeinander Anordnen des ersten und zweiten Substrats (110, 210) unter Ausrichtung des vertikalen Kontaktbereichs (240) mit der Kontaktfläche (150), so dass ein elektrisches Verbinden zwischen der ersten und zweiten integrierten Schaltungsstruktur über den vertikalen Kontaktbereich (240) und der Kontaktfläche (150) hergestellt wird.
Abstract:
A system for performing automated cell screening in drug discovery includes an automated microscope (100), a fast autofocus device, and a digital imaging system (500). Processes are implemented in software through which relevant cellular material is segmented and quantified with minimal user interaction. Improvements in the following areas: known methods for image processing are implemented in such a way that automated segmentation is achieved; sets of known measurements (pixel counting, etc.) are implemented as methods which demonstrate aspects of biology in a reliable fashion; components for automated positioning, focusing, imaging and processing of a multiplicity of samples are integrated as systems within which the segmentation and measurement methods may be mounted; and components and methods are adapted into systems which yield more highly automated and more rapid cell screening.
Abstract:
The present invention relates to an apparatus and method for imaging time resolved fluorescence in biochemical and medical samples. In a primary aspect, the device includes a lens of large aperture, a flash lamp in the illumination path, a fast-acting solid state shutter or a gated detector in the emission path, a device for delivering homogenous monochromatic illumination to a plurality of wells distributed within a microwell plate, a digital camera of high quantum efficiency, and a computer. under computer control, the lamp is pulsed at short intervals. The fast-acting emission shutter or gated detector operates to limit exposure of the camera to a period some microseconds after the extinction of each lamp pulse, during which only delayed fluorescence is transmitted to the camera. The invention achieves simultaneous time resolved imaging of a plurality of samples, with high sensitivity and high throughput.
Abstract:
Bee-keeping is improved by feeding bees with a bee food comprising inactive baker's yeast. This provides increased honey and brood yields in comparison with other forms of yeast and is not harmful as is active baker's yeast. Desirably the inactive baker's yeast is combined with sugars, salt and cholesterol.
