Abstract: A revolver-type feed-through for TEMPEST-grade electromagnetic shielding where one or more non-electric signal leads pass through a wall of a cabinet or other enclosure comprises a housing having a conical inner surface, the housing being attachable to the wall through a first attachment means; and a plug member having a conical outer surface matching the conical inner surface of the housing, the plug member being attachable to the housing through a second attachment means, wherein the conical inner surface of the housing and/or the conical outer surface of the plug member have recesses forming, when the plug member is attached to the housing, a plurality of waveguides. The first attachment means and the second attachment means being operable by one or more operating members located, with the feed-through in installed position, exclusively on one side of the wall, so that the first attachment means and the second attachment means are exclusively operable from the said one side of the wall.

Abstract: A lockable electronics cabinet (1) comprises a body and a door. The door is arranged to be opened in a sequence of motions, comprising, first, a linear motion perpendicular to the plane of the door, then, a rotational motion around a pivot axis.

Abstract: The sanitary diverter valve (70) is for use in a drying system or powder conveying system including conveying lines and a purge line of a purge arrangement. The sanitary diverter valve comprises a valve housing (71) with a number of openings (72, 73, 74) configured to be connected to respective lines of the system. The valve housing (71) is substantially cylindrical and includes a first opening (72), a second opening (73) and a third opening (74). Furthermore, the diverter valve (70) comprises a rotatable diversion member (75) provided with a flow channel (76) having a first end (76a) and a second end (76b), an open space (77) being defined between the valve housing (71) and the rotatable diversion member (75).

Abstract: A feed-through provides electromagnetic shielding where one or more signal leads pass through an enclosure. It comprises a frame, having at least one opening, and an assembly comprising two or more joining parts, forming one or more elongated waveguides. The joining parts are divisible along the length of the waveguides, thereby being capable of surrounding a signal lead. The assembly is adapted to be attached to the frame such that one or more signal leads can pass through an opening in the frame and through one of the waveguides. Installation is of the feed-through is made easier by the opening in the frame having a larger maximum extension than the maximum extension of a waveguide.

Abstract: An aqueous sol containing silica-based particles which sol has a specific surface area of at least 115 m2/g aqueous sol and a pH of at least 10.5, and an S-value within the range of from 10 to 45% and/or contains silica-based particles having a specific surface area of at least 550 and less than about 1200 m2/g SiO2, and wherein the sol is substantially free from aluminium.

Abstract: Silica sols having a high content of microgel and aluminum modified particles with high specific surface area. The sols can be prepared by a process comprising acidification of a water glass solution, alkalization at a certain dry substance content, particle growth and aluminum modification. The sols are particularly suitable for use as additives, in combination with cationic polymers, in papermaking.

Abstract: An aqueous latex material to be used for production of reinforced plastics and binders comprising latex particles of a film-forming organic polymer encapsulated with a layer of acidic, hydrated and hydrogen bound silicic acid in monomeric or oligomeric form.
