Title: Process for the selective sealing of parallel channel ends of ceramic structures, and pasty composition for performing it.
IPC: C03C8/24
Filed: 1982-01-25
Abstract: A method of plugging the ends of selected ducts (5) in a ceramic structure (1). A paste (8, 9) is prepared from a powder and a liquid. The powder comprises a glass whose coefficient of expansion is close to that of the ceramic structure. The liquid comprises a solvent, a plasticizer and an additive which reduces the adherence of the paste to a paste applying tool (6, 7). The tool is used to push paste into the ends of the selected ducts and the ceramic structure is subjected to heat treatment to ensure that the paste adheres to the walls of the ducts and then becomes solid.

Title: Process for producing solutions of hardly soluble substances and for substances tending to agglomerate, and apparatus for carrying out said process.
IPC: B01F33/40
Filed: 1982-03-03
Abstract: In a process for producing solutions of hardly soluble substances and/or substances tending to agglomerate, by introducing the solid into a vigorously agitated solvent, and in an apparatus for carrying out the process, fine gas bubbles are added to the solvent at least during the addition of the solid. This is effected by means of a mixing device which is designed in the manner of an ejector with a downstream addition station for the solid and is located in the region close to the bottom of a dissolving tank. The addition station for the solid is located in the upper region of the dissolving tank and has a charging hopper (14) whose outlet orifice (15) is divided by webs (16). After the valve (3) has been opened, water flows via the line (2) into the tank (1). The water jets issuing from the nozzles (9) draw in air from the annular space (11), which air, dispersed to fine bubbles in the water jet, emerges with the jet through the bores (10) in the tank (1). The webs (16) of the charging hopper (14) ensure that the solid runs in uniformly in a finely dispersed stream.

Title: Digital conference time slot interchanger
IPC: H04M3/56
Filed: 1982-04-22
Abstract: A time slot interchanger is disclosed for selecting and buffering digital signals between buses. The arrangement is particularly useful in forming conferences in a distributed digital time division system. In one embodiment, a clock is used to generate time signals corresponding to time slots of the first bus. These signals are sequentially provided to an associative memory and when a match occurs between the provided signal and a priorly stored time slot identity, an enable signal is provided. The enable signal has a time identity with a first bus time slot and a physical identity with a particular second bus time slot. The enable signal is used to gate into a second memory the time slot signal associated with the time identity at the storage location in the second memory corresponding with the particular time slot of the second bus associated with the enable signal. The signal samples are then sequentially removed from the second memory.

Title: Multi-stage catalytic conversion of aldoses to alditols
IPC: B01J23/74
Filed: 1982-04-23
Abstract: Monosaccharides, such as glucose-water solution, are catalytically hydrogenated by being passed through multiple reaction zones connected in series and each containing a high-activity supported nickel catalyst to produce 99.8 W % overall conversion to an alditol solution such as sorbitol. The pH of liquid in each reaction zone is controlled to between 4.5 and 7 by adding an alkali solution such as sodium hydroxide to the feed to prevent acid leaching of catalyst metal and to help maintain catalyst activity therein. Reaction zone conditions used are 130 DEG -180 DEG C. temperature, 500-2000 psig hydrogen partial pressure, and a ratio of hydrogen gas/feed liquid within the range of about 500-5000. Feedstream liquid space velocity is maintained within range of 0.5-16 Vf/Hr/Vc, with higher space velocities being used for achieving lower incremental conversion desired in the subsequent reaction zones to help maintain pH of the effluent liquid within the desired range. The first reactor is preferably a back-mixed ebullated-catalyst-bed type to achieve 60-80 W % incremental conversion, the last reactor is a fixed-catalyst-bed type to achieve 5-20 W % incremental conversion, and three catalytic reaction zones are preferred.

Title: Design of stackable unencapsulated power semiconductors for evaporative cooling
IPC: H01L23/427
Filed: 1984-11-05
Abstract: In the case of an arrangement of an unencapsulated power semiconductor wafer (1) which is immersed in an evaporative cooling liquid and which is radially fixed between two heat dissipaters (2, 3), which serve as anode-side and cathode-side connections, by three axially extending plastic holding devices and is axially clamped by means of insulated tie bolts (7), the intention is that many of these devices can be pressed together to form stacks but that an adequate surface of the heat dissipaters (2, 3) can nevertheless be provided for evaporative cooling without film boiling. For this purpose, the heat dissipaters (2, 3) are provided with spacing protrusions (8) on the side remote from the power semiconductor wafer (1). The clamping force (P) of the tie bolts (7) is transmitted to the power semiconductor wafer via said spacing protrusions (8). The plastic holding devices are designed as insulating studs (9) which are embedded in one of the heat dissipaters (2 or 3) and which form a snap holding device for the power semiconductor wafer (1) so that a compact and simple assembly is achieved at the same time.

Patent ES-8800431-A1 (ES)
Title: Detecting defects in transparent articles.
IPC: G01N21/90
Filed: 1985-12-26
Abstract: An apparatus and method for detecting sidewall and dimensional defects in transparent containers includes a laser scanning system (40, 42, 44) positioned astride a conveyor (12) in a production line. In an upstream inspection zone a laser beam vertically scans a portion of the side wall of the container. Photosensors (62, 64, 66, 68) positioned in a detection chamber (56) detect the specific effect which any defect has upon the laser beam by determining the location of light passing through the container and comparing its intensity against pre-set thresholds. A flaw signal is generated when a threshold is exceeded. The number of flaw signals is counted (78) and when the count equals a pre-set value a reject signal is generated (98) to eject the defective container from the conveyor. If a container is not rejected, is passes through a rotator assembly which rotates the container precisely 90 DEG . The container then continues to a similar downstream inspection zone where an indentical scanning and detection process is repeated with regard to the previously uninspected portions of the side wall of the container.
