Abstract: A structure and method for repairing SDRAM by generating a Slicing Table of Fault Distribution and using the size of SDRAM page as the partition basic block. The Slicing Table of Fault Distribution is generated at each booting or memory-testing, and the elemental range of the number of detected defects is formed. When the number of detected defects exceeds the elemental range, the limits of another partition block with a lower rate of defects are used to cure the defect. The repair bit is also encoded according to the Slicing Table of Fault Distribution, pointing to the remapping bit so that the access operation occurs at the remapping bit. As such, the cost of producing, testing and repairing SDRAM is greatly reduced.

Abstract: The invention concerns a process and a device for taking samples in particular from waste gases containing substances of moderate and low volatility in a gas or aerosol phase. To this end, a partial current is diverted and conducted into a separation area (10), where the substances to be tested from the partial current, either in dust-bonding form or in the condensate, undergo a separation process and are fixed. When applied to a specific sample for the analysis of organic substances of medium to low volatility, in particular polychlorinated dibenzo(p)dioxins (PCDD) and polychlorinated dibenzofurans (PCDF), the separation process can be restricted according to the invention in such a way that the partial current, together with the gaseous and liquid water portion contained in it, undergoes a two-stage separation process, where it is drawn through an inert dust-filter region (11), and drawn through a region (12) filled with an adsorber such as a synthetic adsorbent resin with a multi-reticular structure.

The cassette has at least one electrically conductive element (6) which covers at least 20% of the surface of the cassette (1).

Abstract: A system for retrieving a packet of informational digital data which is stored on a secure storage medium. The informational data packet (IDP) is read from the secure storage medium and then expanded in length to form a sequence of digital data which is so large as to be inconvenient for permanent storage.

Abstract: In order to allow conductors or wires having different cross sections to be easily and reliably stripped, the swivelling axis pin of a stripper is designed as a double axis pin whose first substantially cylindrical pivot is arranged in a first leg and whose second substantially cylindrical pivot is arranged in a second leg. Both pivots are held and guided in an intermediate element. This sliding hinge allows both legs with their cutting tool parts to be held as forceps and to be pressed against each other and slid in one direction with respect to each other by actuating guiding elements arranged on the legs.

Abstract: A miniaturized sensor component for measuring concentrations of substances in liquids comprises a support that contains cavities accommodating a membrane. The membrane is produced in situ by polymerization or by precipitation from a solution. An electric lead is either mechanically connected to or integrated into the membrane and is in contact with the membrane. The membrane support is a capillarized solid and the membrane is produced in the capillaries by impregnating the support with a liquid that subsequently either polymerizes or evaporates leaving a residue.

Abstract: In order for an apparatus for the sorting of objects, especially those of flat shape, to permit a simple and horizontal distribution of the objects, an endlessly circulating primary roller conveyor (2) is divided into roller sections (3.1, . . . ) of rollers (7.1.1, . . . , 7.1.n, 7.n.1, . . . 7.n.n) arranged in groups with window sections (5.1, . . . ) as gaps between them. Underneath the upper conveyor plane (upper run 2.1) and the lower return plane (lower run 2.2), secondary conveyors (11.1, . . . , 12.1, . . . ) are disposed in the intermediate space (2.3) of the roller conveyor (2). Roll-off systems (6.1, . . . ) are associated with the secondary conveyors, which, when operated by a control system, contact the rollers (7.1.1, . . . , 7.1.n, . . . , 7.n.1, . . . 7.n.n) of a roller section (3.1, . . . ), so that the object (4.1, . . . ) lying thereon is rolled away against the direction of movement of the roller conveyor (2) and falls through the window section (5.1, . . .

Abstract: A method of automatically controlling exposure when printing from film which is exposed under controlled lighting conditions. The prevailing lighting conditions are determined by photographing a standard subject in the form of a gray-scale board with at least one field of gray and illuminated by the studio lighting. The gray scale is recognized as a standard subject during region-by-region analysis of the film's frames and the results obtained from the gray scale are employed as a film-specific standard in computing the levels of light to use for printing.

The collar has a continuous annular groove around it that cuts into its contour radially, and the ring is secured in the groove just by snapping into it. The ring and the rotatable component rest loosely against each other, when the component is not rotating, without internal tension in the ring.

Abstract: Apparatus for developing a photographic emulsion carrier. The carrier travels through a succession of tanks of photographic processing fluid. The apparatus includes mechanisms that forward the carrier through the tanks, a drive device that operates the forwarding mechanisms, guides that guide the carrier from one tank into the next, and means that connect an inlet for each processing fluid with its associated tank. The apparatus also includes at least one separate assembly associated with at least one tank, for forming a cascade which includes means for conveying the processing fluid from at least one cascade stage to the tank. The assembly, for forming the cascade is a separate module that rests as a cover on the tanks and has a separate inlet for receiving processing fluid. The cascade assembly accommodates a mechanism that forwards the carrier through it. This mechanism couples with the mechanisms that forward the carrier through the tanks while the cascade assembly is resting on them.

Abstract: A digital computer system and method for storing and retrieving data contained in a "relational data table" in such a way that individual items of data are readily accessible and the data itself is compressible. The items of data are arranged in the table in a plurality of rows and columns. The items of data in each given column are of the same type (fixed length character, variable length up to a prescribed maximum length, etc.). The items of data are arranged in a particular data format which comprises a plurality of "column descriptor" or "C" records, each of which is associated with one column of the table, followed by a plurality of "data" or "D" records which include the items of data in the table. The D records and C records contain the following information: Each D record includes one or more of the items of data from a particular table row. It is therefore associated with this table row and with at least one table column.

Abstract: The invention relates to a relation computer 3 for the simulation of cerebral cortex of a biological brain. The relation computer has a trito counter 4 consisting of several trito cells Zi each having one tritogram Ti associated therewith. Each of these cells Zi is connected to a computer group Si which has number of computer places that is associated with the valuedness of the tritogram. When information is supplied to a computer group Si and then computed, an activity unit 9 of this computer group is activated which supplies a signal to the corresponding trito cell Zi. The tritograms of the instantaneously activated trito cells Zi are stored in a pattern memory 6 in certain time intervals. The most frequently occurring tritogram patterns are counted in an occurrence counter 7. They can then be fed to an action intention computer 1 in order to modify possible action programs. The organization of the relation computer can also .

The polyolefin mixture comprising the coating contains at least one copolymer of an .alpha.-olefin with an .alpha., .beta.-unsaturated carboxylic acid. At least 5% and preferably 20% to 80% by weight of the mixture is copolymer.

Abstract: A personal computer or "host computer" and a Mass storage device are arranged on an SCSI bus. A "decryption controller", in a separate enclosure outside of the host computer, is also arranged on the SCSI bus. This controller is addressable by the host computer as if it were the mass storage device. Upon receipt of an information request, the decryption controller initiates a request to the mass storage device for the desired information, retrieves this information, decrypts it (if it is encrypted) and then passes it to the host computer. The decryption controller is thus "transparent" to the host computer.

Abstract: An X-ray sheet film cassette is assembled of a bottom wall, side walls and a cover hinged to an upper part of one side wall. The lower part of the one side wall adjoining the bottom wall is reduced in thickness to form an abutment for the sheet film. The inner surface of the cover is provided with a resilient pressing pad which during the closing of the cover urges the sheet film against the abutment and in the closed condition of the cassette presses the film against the bottom. In this manner, when taking X-ray pictures of a part of patient's body which forms an angle relative to another body part, the unexposed section of the first mentioned body part which is adjacent the other body part, is minimized and well defined in position relative to the other body part.
