Abstract: A probe card apparatus and method which allows recon­figuration of the probing circuits. A first probe card member (31) has a plurality of incomplete probing circuits which are associated with a plurality of contact holes (51, 52, etc.). An adapter ring member (33), having a plurality of T-shaped conductive lines terminated in contact holes (51′, 52′, 53′), is removably mounted in close proximity to the first probe card member (31). Spring-loaded contact pins (61, 62, 63) provide contact between the members such that the T-shaped conductive lines are used to complete the probing circuit. The T-shaped conductive lines are severable lines, and discrete electronic components can be connected between respective contact holes. As the adapter ring member (33) is of a removably attachable construction, the entire probe card circuitry is reconfigurable by a simple change of the adapter ring.

Abstract: Triglycerides of fatty acids can be obtained by reaction of fatty acid alkyl esters with glycerol in the presence of sodium carbonate as catalyst by metering a mixture of dry sodium carbonate and glycerol to the heated, dry fatty acid alkyl esters at such a rate that the solubility of the glycerol in the reaction system is not or not substantially exceeded, adding further fatty acid alkyl ester, after addition of the glycerol, to the boiling reaction mixture in order to react unconverted glycerol, continuously distilling off the alcohol formed, removing fatty acid alkyl ester from the reaction mixture obtained by distillation, separating off precipitated sodium carbonate, and purifying the fatty acid triglyceride in the usual manner. …<IMAGE>…

Abstract: A method and apparatus for creating a transitive closure of a database when the database is stored on a secondary storage in the form of links connecting nodes. The method consists of partitioning the database, transferring one partition at a time from the secondary storage to the main memory, and processing a partition in such a way that accesses to the portions of the database not in main memory are minimized. As much of the unprocessed database as would fit a predetermined fraction of main memory is fetched as one partition, and if, during the processing of this partition, the main memory becomes full, the size of the partition is reduced dynamically by discarding a portion of the database in the current partition, and including this portion in the next partition. The processing of a partition involves, for each node in the partition, the operation of creating a direct connection between every pair of nodes that are indirectly connected through this node.

Abstract: The invention relates to a method in a multi-colour silk-­screen printer having a parality of printing stations for orientating in each of the printing stations a second pattern (7a), deriving from a pattern (6a) carried by a stencil (6) in relation to print material (7) intended to receive the second pattern, so that the second pattern (7a) will have a pre­determined position in relation to the print material (7). The second pattern (7a) is formed by causing coating substance to pass, in one printing position, through the first pattern (6a) and on to the print material, for example with the aid of a squeegee arrangement. 
     For the purpose of calibrating a control unit (8) incorporated in the silk-screen printer it is proposed;
     a) that the position of the material in relation to a reference value, e.g. the printer chassis, is read-off (11,12) in a first registered position (A), a material feed position, and the resultant measurement value stored;   b) that the print material is moved to a second registered position, a printing position in a first printing station, in order to receive the second pattern belonging to the first printing station;   c) that the print material (7) to which the second pattern (7a) has been applied in accordance with "b" above is moved back to the first registered position (A), in order to read-off the position of the printed second pattern (7a) in this registered position relative to the reference position stored in the control unit (8); and     d) that the stencil frame carrying the first pattern in the first printing station is displaced in response to the established discrepancy between the actual position of the pattern, obtained when effecting the transfer according to "b" above, and its pre-determined position, to an extent and in a direction such that the established discrepancy is minimised when printing subsequent print material.

Abstract: Under certain operating conditions, an emulsion of an acidified unfiltrable tarry bottoms stream from a reactor for the chlorination of ethylene to 1,2-dichloroethane can be demulsified and separated in a phase separation tank. The presence of FeCl₃ in an amount more than 5 ppm Fe in the separated organic waste, fouls the reboiler and lower internals of a "heavies" column in which the separated organic waste is concentrated, and deactivates the cata­lyst in a Catoxid fluid bed reactor in which the concen­trate is burned. By maintaining an iron salt chlorination catalyst in a concentration which results in 2000 ppm to 4000 ppm of Fe in the HTC reactor bottoms, and operating the HTC reactor at a temperature in the range from about 90°C to 120°C and a pressure in the range from 9 psig to 12 psig, an unfiltrable reactor bottoms drawoff is produc­ed which may be acidified without forming an emulsion. Formation of an emulsion is avoided by mixing each volume of the HTC bottoms drawoff with at least 50 volumes of dilute aqueous HCl in a concentration range from 2 to 4% so as to demulsify the emulsion into aqueous acid and organic phases. The mixture is gravity-separated in a phase separation tank by decantation. The lower layer (60-­70% by wt EDC, the remainder being heavies) is concentrat­ed by recovering EDC overhead and producing a bottoms concentrate in which the Fe is present in no more than 50 ppm. The concentrate may be economically disposed of in a Catoxid reactor using a support-free gamma alumina cata­lyst found to be highly sensitive to iron.

Abstract: The first improvement described relates to the gasket (20) between the ink reservoir (15), with its nozzle plate (61) attached, and the drop generator body (11) that encloses the dynamic pressure transducer (13). If this gasket (20) is formed of very soft material, having a durometer value in the order of 60, then it is only necessary to clamp the plate (61) to the drop generator body (11) with sufficient torque to seat and seal the ink reservoir (15) to prevent ink leakage. 
     The second improvement described requires a small space (59, 60) between each crystal (52) in a piezoelectric transducer (15) and the washer (58) of acoustic-absorbing material, and the third improvement involves the support rod (56) for these crystals. The support rod (56) should fit with sufficient frictional force to retain the crystals (52) in a preset position, avoiding all unnecessary extra loading of the crystals.

A first violation detection circuit (28) receives the second detection signal (d) and the first enable signal (e) and generates a first code violation detection signal (g) when the second detection signal (d) is generated during the active period of the first enable signal (e). A second violation detection circuit (20) receives the first detection signal (c) and the second enable signal (f) and generates a second code violation detection (h) signal when the first detection signal (c) is generated during the active period of the second enable signal (f).
