Abstract: The process for producing a hard, shapable material with channels for the passage of fluids and which can be reduced in size at their exit points on the surface and which material has a desired bulk density, can be produced in that a cluster of several particles is formed from particles with the aid of a binder and said cluster is brought into the form of a cohesive structure with the aid of a binder in a further working step and the structure has a plurality of interconnected cavities. The porosity of the surface is reduced by breaking down surface clusters into fragments and embedding them in surface openings.

Abstract: A method of gel electrophoresis carried out in a submerged gel mode in which the gel is a bed of water insoluble, transparent, cross linked gel, which has been formed by: dissolving a polysaccharide, including at least one linear polysaccharide such as agarose or hydroxyethyl cellulose, in a suitable solvent, such as water; adding a cross linking agent, which is not charged nor becomes charged upon contact with water in a pH in the range of about 2 to 11, to the solution; and incubating this mixture in a quiescent state to substantially simultaneously react the polysaccharide and the cross linking agent and to gel the reaction product into a bed. The polysaccharide is at least one linear polysaccharides, but that linear polysaccharide may also be admixed with other linear polysaccharides and/or at least one non-linear polysaccharide. Synthetic organic polymers may also be admixed in the cross linking reaction mixture.

Abstract: A rake having multiple rows of tines in alternating rows alternate in a lateral position and are spaced from each other sidewise. In a preferred embodiment, the rows of tines are so spaced that the tines of one row are individually offset with respect to the tines in the next adjacent row and thus are located substantially between the tines of the next row.

These logarithmic values are plotted to provide a seismogram with the seismic reflection signals being recorded in side-by-side trace relationship.

Abstract: A method and apparatus for feeding catalyst, oil and steam into a fluid catalytic cracking (FCC) riser. Oil passes through respective oil lines into a multiplicity of upwardly extending nozzles located at a lower portion of the riser, while steam passes through respective steam lines into the nozzles where it blends with the oil, with the combined oil and steam mixture being fed through the nozzles into the riser. Each oil line and steam line is provided with a valve to separately control oil and steam flow rates, respectively, in each of the nozzles to obtain a substantially constant catalyst to oil ratio across a horizontal cross-section of the riser. The substantially constant catalyst to oil ratio is represented by a substantially isothermal temperature profile across the horizontal riser cross-section, which is detected by measuring the temperature at various points along the horizontal cross-section.

Abstract: This method and apparatus optically samples numerous points on the surface of an object to remotely sense its shape utilizing two stages. The first stage employs a moveable non-contact scanner, which in normal operation sweeps a narrow beam of light across the object, illuminating a single point of the object at any given instant in time. The location of that point relative to the scanner is sensed by multiple linear photodetector arrays behind lenses in the scanner. These sense the location by measuring the relative angular parallax of the point. The second stage employs multiple fixed but widely separated photoelectronic sensors, similar to those in the scanner, to detect the locations of several light sources affixed to the scanner, thereby defining the absolute spatial positions and orientations of the scanner. Individual light sources are distinguished by time-multiplexing their on-off states.
