Abstract: An inflatable seal for sealing an annular space between two flange parts is formed by a hollow ring composed of elastic material. The hollow ring has a tubular cross-section with a peripheral wall and is provided with a connection for an inflation medium. The peripheral wall comprises, in at least one area of the tubular cross-section, a blocking element having a substantially larger cross-sectional dimension than the remaining part of the peripheral wall. Furthermore, a set of flange parts and a container comprising such a seal, and a method of manufacturing such a seal are disclosed.

Abstract: A measuring device (1) comprises a probe body (4) adapted for connection with a process vessel or conduit, so that a process opening (6) of the probe body communicates with the interior of the process vessel or conduit. A front valve (7) is arranged between the process opening and a washing chamber (5) in the probe body, and a probe piston (3) is arranged displaceably in the probe body between a retracted position, in which the probe piston is located behind the front valve (7), inside the washing chamber (5), and an extended position, in which the probe piston extends through the front valve and communicates with the process opening. A back valve (9) is arranged between the front valve and the washing chamber, and an intermediate chamber (8) is arranged between the front valve and the back valve. In its retracted position, the probe piston is located behind the back valve.

Abstract: A process for coating bodies comprising: producing an upward spray of coating fluid by means of a two-fluid nozzle to create a coating zone, and contacting the bodies with the spray of coating fluid in the coating zone; wherein, before contacting the bodies with the spray, providing the bodies with a spinning movement by a central impact of gas jets directed upward to intersect the centerline of the spray; guiding the spinning bodies by the gas jets towards a central position over the two-fluid nozzle, thereby increasing the number of suspended bodies contacting the spray; providing atomization gas to the two-fluid nozzle in an amount less than the one which, after moderation by means of muffling gas, would scatter the bodies in the spray zone; and pneumatically muffling the atomization gas just above the nozzle to reduce the body scattering effect thereof; and further wherein, the bodies are pneumatically transported in the coating zone in a non-fluidized state.

Abstract: A sampling device (1) comprises a sampling container (4) for reception of a sample volume and a connecting piece (7) adapted to be connected to a fitting (2) mounted on a processing installation. The connecting piece (7) has a sample passage which is provided with a stationary valve part (12) and a corresponding valve member (14) which is displaceable between a closed and an open position. The stationary valve part (12) and the displaceable valve member (14) are integrated in the sampling container (4). The valve member (14) is spring-loaded towards its closed position and adapted to be automatically displaced to its open position upon connection of the connecting piece (7) with the fitting (2).

Abstract: Bodies, including tablets, are coated by producing an upward spray of coating fluid by means of a two-fluid nozzle as defined herein; before contacting the bodies with said spray, providing the bodies with a spinning movement by a central impact of gas jets directed upward to intersect the centerline of said spray; guiding the spinning bodies by said gas jets towards a central position over the two-fluid nozzle, thereby increasing the number of suspended bodies contacting the spray; providing atomization gas to the two-fluid nozzle in an amount less than the one which after moderation by means of muffling gas would scatter the bodies in the spray zone; and pneumatically muffling the atomization gas just above the nozzle to reduce the body scattering effect thereof.

Abstract: In a process for coating particles, in which the particles are circulated upwards through a first spraying and drying zone and downwards through a second drying and residence zone, the capacity is increased and agglomeration avoided by using a lower temperature of gas supplied to said second residence and drying zone than the temperature of the gas supplied to said first spraying and drying zone.

Abstract: In a granulation process only a small proportion of the material being treated is at any time subjected to a wetting and collision followed by a very fast drying whereby harmful increase of moisture content in the powder is avoided. By the process the particles to be granulated are sprayed with granulation liquid, brought into mutual contact, and dried while influenced by a fast swirling- upward gas stream in a vertical pipe. The fast drying prevents excessive penetration of coating liquid into the interior of the particles. The low moisture content during the process involves operational advantages and allow for interruption and re-start of the operation at any time.

Abstract: In an apparatus for producing and/or processing granules, pellets or other particulate materials, having a rotary disc tight within a chamber and means for providing an upward gas stream through a slot between said disc and the chamber wall as well as means for spraying a liquid or steam onto the particulate material and possibly means for introducing powder for use in a powder layering process, the flow patter of the particulate material, which is maintained in non-fluidized condition, is improved by gas injection towards the center of the chamber or disc. A more uniform product having desired properties is obtained and the capacity is improved. The gas injection enables upscaling of apparatus and method.

Abstract: A non-fluidized bed apparatus for coating tablets has a base plate of which a portion of the upper surface is inclined towards an upward directed two-fluid or three-fluid nozzle. Ducts through the base plate around the nozzle produce jets of process gas in a direction intersecting an imaginary centre line of the spray produced by the nozzle. Atomizing gas from the nozzle is muffled shortly after it has left the nozzle to decrease the upward scattering effect of said gas on the tablets being coated. No partition is used for separating upward and downward flow of tablets during the coating process. In the coating process the amount of atomizing gas supplied to the nozzle is limited to reduce the tablet scattering effect of said gas.

Abstract: An apparatus for coating discrete solid particles has one or more coating units, each comprising an upward directed nozzle (5), an annular opening (6) around the nozzle, wall means (7), such as a vertical pipe, above the opening but spaced therefrom, and gas guiding walls (9) below the annular opening for accelerating a gas stream flowing towards said opening. Between said guiding walls, means (10) are arranged for imparting a swirling flow to said gas stream. Thereby the particles are coated while being conveyed in a swirling gas flow. The coating quality is improved and operation facilitated.
