Abstract: A sealable contamination proof container package bottom and top for storing and transporting a plurality of substrate or wafers in a robotic wafer carrier. The package bottom includes four sides, a continuous vertical surface for tape sealing surrounding the four sides, a lip positioned on a vertical edge, opposing hook latches on opposing sides, opposing hand grip recesses on the opposing sides and a raised bottom surface for package stacking. The package top includes four sides, a continuous vertical surface for tape sealing surrounding the four sides, a lip positioned on the vertical surface, opposing hook catches on the opposing side, a top surface with raised stacking surfaces, and two rows of wafer support springs positioned on bars on the underside of the top surface. The package top and bottom halves provide that the robotic wafer carrier mates between the package top and package bottom with the wafers or substrates in the carrier. The package top and bottom mate with the upper lip engaged with the lower lip, and the catches of the top engage with the latches of the bottom. The package halves are designed in such a fashion as to prevent wafer or substrate damage upon opening, in that the top package half is moved in a direction coinciding to the plane of the wafers or substrates with respect to positioning of the catches and latches on the package side. Appropriate sides of the package top and bottom are plumb with each other providing for a flush perimeter for ease of taping. The raised top portion of the top package half and the recessed bottom of the bottom package half provides for stacking of like packages. In an alternative embodiment, opposing rows of articulated cantilevered horizontal arms with centering V grooves on each end for engaging a wafer, disk or substrate extend inwardly from the edges of an arced top surface in the package top.

Abstract: The cooling device comprises a tubular rectilinear conduit (1) pierced with a plurality of passages (C1.01,...,C8.12) arranged in plane rings (C1,...,C8) perpendicular to the longitudinal axis of the conduit (1) and angularly offset with respect to one another. Seen in the direction of movement of the cylindrical element, each passage belonging to any one of the rings (C1,...,C8), with the exception of the first (C1), is located substantially at the centre of the circumferential distance separating the generatrices of the tubular conduit (1) which pass via two angularly successive passages in the set of rings preceding the ring in question. The set of rings may be divided into groups (G1, G2, G3) which follow one another in the direction of movement, each group comprising a number of rings which is sufficient to include a passage located at the centre of each of the circumferential distances separating the generatrices which pass via two angularly successive passages in the set of rings preceding the group in question. <IMAGE>

Date Jul. 26, 1990.A furnace for high temperature, for example a glass furnace, is insulated thermally by arranging layers of material on the interior wall of the furnace shell. On the layers ceramic fibre material and a heat reflecting surface layer are arranged. According to the invention, the heat reflecting surface layer is arranged by a substance containing silicon. By subjecting the furnace to great heat and cooling it rapidly thereafter, a heat reflection is obtained in the micro-structure of the ceramic fibre. The substance may for example be water-glass. According to the invention, the fibre material is arranged in vertical blocks of trapezium form, then pressed and strapped up. After all blocks have been placed, one removes the strapping so that the blocks expand.

Abstract: A heat exchanger for cooling hot raw gas with aggressive constituents and for heating the pure gas obtained by purification of the raw gas comprises a housing with two side walls and an upper and a lower tubesheet. The inner side walls are associated with partitions to form flow channels. The ends of a plurality of exchanger tubes parallel to each other and to the side walls are inserted in the upper and lower tubesheets. The hot raw gas flows through the exchanger tubes and the pure gas flows through the housing perpendicular to the exchanger tubes. The housing and the partitions are made preferably of highly corrosion-resistant sheet metal and the exchanger tubes are made preferably of glass. To improve this type of heat exchanger so as to obtain the desired heating of the side walls and hence prevent corrosive condensation, with a relatively simple structure, the pure gas outlet from the heat exchanger communicates through at least one pure gas duct (4) with the flow channels (4) of the two side walls (3). The pure gas ducts (4) open into the upper and/or lower regions of the flow channels (14). The flow channels (14) have front outlet orifices (10) for the recycled pure gas.

Abstract: A known water-collection tank for separating or unsticking surface coating agents has provision for an outflow-side cross-channel (8) to be connected to the said tank, which channel has an outflow slope (13) and a calming zone (10) with slowly flowing calming flow and a comparatively large depth. It is proposed to design the abovementioned cross-channel (8) not to be deep but rather, for the most part, to have an essentially horizontal flat flow section, in particular by arranging an intermediate floor. Due to the small depth, the fed-in particles of surface coating agent which contain air are held in the region of the surface of the water. The particles of surface coating agent which float up can be easily removed with simple, preferably mechanical means from the water which is then purified. <IMAGE>

Abstract: A loudspeaker system has at least a first electroacoustical transducer ( 12 ) having a vibratable diaphragm for converting an input electrical signal into a corresponding acoustic output signal. An enclosure is divided into at least first, second and third subchambers (V1,V2,V3) by at least first (13) and second (11) dividing walls. The first dividing wall (13) supports and coacts with the first electrical transducer (12) to bound the first and second subchambers (V1,V2). At least a first passive radiator (P1) intercouples the first and third subchambers. At least a second passive radiator (P2) intercouples at least one of the second and third subchambers with the region outside the enclosure. Each passive radiator (P1,P2) has an acoustic mass and each subchamber (V1, V2, V3) has an acoustic compliance. The acoustic masses and acoustic compliances coact to establish at least three spaced frequencies in the passband of the loudspeaker system at which the deflection characteristic of the vibratable diaphragm as a function of frequency has a minimum. <IMAGE>

Abstract: A standard control signal for a web forming machine is temporarily interrupted and replaced by a perturbing signal or signals which are applied to one, a grouping, or all of a series of actuation cells of the web forming machine. One or more actuation cells are driven with an alternating perturbing signal(s) which generate a corresponding action in the actuation cell(s). The perturbing signal(s) alternates from a neutral position of the cell and is selected to minimize mean effects over any given period of time. The effects of the alternating signal(s) on the web appear within the area of the web which is affected by the actuation cell(s) such that the mapping and the response of the actuation cell(s) can be determined by monitoring that portion of the web which is formed while the alternating signal(s) is applied to the actuation cell(s). The mapping(s) and/or response(s) of the actuation cell(s) are obtained by correlating the perturbing signal(s) and a web property signal or profile signal obtained by monitoring the web formed by the machine. The perturbing signal(s) is defined by a pseudo-random binary sequence with multiple signals being selected to be statistically independent of one another. To ensure that the web is not perturbed beyond defined specifications, the perturbing signal preferably is gradually increased in amplitude and is terminated individually for each actuation cell upon reaching a usable amplitude.
