Abstract: The invention relates to novel substrates for soilless culture. 
<??>The substrates are formed by a felt of mineral fibres which present a water retention gradient in such a way that the water retention decreases in the direction of gravity. 
<??>Substrate I presents a water retention gradient due to a gradient in fibre fineness in such a way that the mean diameter of the fibres increases in the direction of gravity. In substrate II, the diameter of the fibres varies in the opposite direction. Water retention is higher in substrate I than in substrate II.

Granted: 1998-03-17
Abstract: 94 An improved stereolithography system for generating a three-dimensional object by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, information defining the object being structurally specified to reduce curl, stress and distortion in the ultimately formed object, the successive adjacent laminae, representing corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming process. A stereolithographic distortion known as curl is defined, and several techniques to eliminate or reduce curl are described, including dashed line, bent line, secondary structure, rivets, and multi-pass techniques. In addition, a quantitative measurement of curl known as the curl factor, and a test part known as a quarter cylinder are described, which together can be used to measure the effectiveness of the above techniques in reducing curl.

Abstract: - 21 -                   54,134 ABSTRACT            Novel methods for repairing worn surfaces of steam turbine components and especially high pressure turbine rotors, are disclosed. The e methods include depositing a first layer of weld metal on a worn surface of the component, whereby a heat-affected zone is created. A second layer of weld metal is then deposited over the first layer using a greater amount of heat to temper at least a portion of the heat-affected zone produced by the first layer. The preferred embodiments include the use of gas tungsten arc welding for producing fine-grain size and more creep resistance, especially in the weld and heat-affected zone. The resulting build-up can be machined, for example into a blade fastening to produce a component having properties equal to or better than the base-metal alloy. The invention also provides a longer lasting turbine system including rotors which have serrated steeples that are more resistant to failure.

Abstract: ABSTRACT of the DISCLOSURE    An optical system for a bar code scanner has a working  range  that  is  not  determined  by  the  lens aperture, but by the dimension and orientation of the detector.   In the preferred embodiment,  the desired working range is imaged onto a detector array using a modified Scheimpflug arrangement.   The array in the first Scheimpflug plane with respect to the lens defines a second Scheimpflug plane that intersects the bar code tag to be read.  So long as the bar code tag intersects the  image  of  the  detector  array  in  the  second Scheimpflug plane, a portion of the image of the bar code tag will be in focus on at least one of the elements of the detector array.  The lens aperture can be as  large as desired to maximize resolution and minimize illumination needs without adversely affecting the working range.  The scanner's bar code illumination can be directed along the second Scheimpflug plane, which is off the optical axis of the lens.   With separate illumination and detection paths, the optical system of the invention does not require beam splitters or   mirror/aperture   arrangements   needed   by   the conventional systems.
