Abstract: The present invention relates to a hydroxy-sulphureous acid, to a method for preparation of the hydroxysulphureous acid and to products based on said hydroxysulphureous acid, to methods for preparation of said products and to use of said products, wherein said hydroxysulphureous acid is used as building blocks for polymer systems, e g aqueous polymer systems such as inks, coatings, and adhesives.

Abstract: A method for coating a floor, wherein said method comprises applying an aqueous dispersion comprising polyurethane, an acrylate or a hybride or mixture thereof; drying said coating and subjecting the physically dry coating to ultraviolet radiation whereby a cured coating is obtained. Also claimed is reactive additives suitable for use in the methods as well as the floor itself.

Abstract: A safety coupling for the releasable connection of a nozzle to a duct system is disclosed. The safety coupling is adjustable between a coupled position, in which the coupling parts are coupled together to lock the connection of the nozzle to the duct system, and a decoupled position, in which the coupling parts are separable to allow release of the nozzle from the duct system. An actuating member is arranged to move the coupling member from the coupled position into the decoupled position when the coupling member is subjected to a disengagement force exceeding a predetermined limit value.

Abstract: The invention relates to a safety coupling, for the releasable connection of a nozzle to a duct system, which nozzle and duct system form part of an extraction system. The safety coupling comprises a coupling member having a first coupling part, which is adapted for fitting in the nozzle, and a second coupling part, which is adapted for fitting in the duct system. The first and second coupling parts are adapted to be brought together for connection of the nozzle to the duct system. In the joined state of the coupling parts, the coupling member is adjustable between a coupled position, in which the coupling parts are coupled together to lock the connection of the nozzle to the duct system, and a decoupled position, in which the coupling parts are separable to allow release of the nozzle from the duct system.

Abstract: An apparatus for lifting and moving articles, comprising at least one arrangement with a vacuum chamber, which is connected to an arrangement which is capable of producing negative pressure in the vacuum chamber, the underside of a lower plate being provided with an elastic airtight bottom and also being provided with a number of first through-passages to the vacuum chamber.

Abstract: A saw for cutting off plaster casts and the like. A single freely reciprocal sawblade is driven by a motor for providing cutting of a cast of the like. A flat guiding plate is disposed in the same vertical plane as the sawblade, and is spaced from the rear of the blade, a lower anvil is provided for engagement with the bottom surface of a cast being cut and for guiding the reciprocatory motion of the sawblade, and a spring-pressed gliding plate is disposed generally forwardly of the blade and engages the upper surface of a cast being cut. The gliding plate and anvil overlap over a substantial length thereof, and firmly hold the cast in place during cutting.
