Abstract: An amphipathic gel according to the invention is characterized in that a hydrophobic group is coupled to a hydrophilic gel through a bridge which comprises thio-ether-sulphur. The gel may be a cross-linked polysaccharide, a polyacrylic acid derivative or an inorganic substance, such as silica gel or glass or a derivative thereof, and the hydrophobic group may comprise, in addition to the thio-ether-sulphur, alkyl, alkenyl, cycloalkenyl, alkaryl, aralkyl, heteroaryl, alkheteroalkyl, and unsubstituted or substituted with electrically neutral substituents. The gel is prepared by introducing an oxirane group or thiosulphate group into a hydrophilic gel and subsequently bringing the gel into contact with a hydrophobic mercaptan in an alkaline solution. The gel according to the invention can be used for the adsorption and desorption of amphipathic substances, and affords better separation than earlier similar products in which the hydrophobic ligand is bound to the hydrophilic gel over an oxygen bridge.

Abstract: Suspension device in a bogie for a railbound vehicle, especially for freight cars. To obtain good ride properties both under empty load and full load conditions, a progressive suspension unit (22) is proposed, the stiffness of which increases exponentially with the load. According to the invention, the suspension unit (22) comprises two essentially cup-shaped elements, one (28) mounted under the bolster beam (30) and friction wedge dampers (32,34) and the other (26) mounted on top of the underhung U-bracket (20). Between these cup-shaped element an essentially spherical or semi-spherical elastic body (24) of rubber or an equivalent material is sandwiched. In alternative embodiments of the invention the lower cup-shaped element (26) is dispensed with by the elastic body (24 min  or 24 sec ) directly resting on a shaped portion of the underhung U-bracket (38 or 40), which performs the same function as the eliminated lower cup-shaped element (26). The cup-shaped elements (26, 28) are formed so as to control the shape of the elastic body (24) during its compression to obtain a progressive spring characteristic both in the vertical and in the lateral direction.

Abstract: The headbox for a paper making machine includes an outlet duct extending across the machine width. The outlet duct is defined by a fixed duct wall below and by a movable duct wall above which are oriented to converge and define an outlet slot. The movable duct wall is movable by a lifting appliance to adjust the space between the duct walls and also the pressure on the stock suspension passing the outlet slot. The movable duct wall has a duct wall beam disposed on it. A support beam for the movable duct wall extends across the machine. Between the duct wall beam and the support beam is a pressure cushion which acts against the pressure in the outlet duct. The lifting appliance is pivoted on the rigid headbox housing and on the support beam. The lifting appliance meets the movable duct wall beam at its axial end to avoid bending moments on that wall. Alternatively, the lifting appliance meets the support beam axially outward of the axial ends of the movable duct wall and a flexible connection between the movable duct wall and the appliance avoids bending moments on the movable duct wall.

Abstract: A method for fermentation of especially highly viscous substrate is carried through with a controlled mixing of air. The addition of air takes place in two steps, where in the first step a small amount of substrate is mixed with a larger amount of air such that a foam containing air bubbles is formed. In the second step the foam is distributed and mixed into the substrate in a mixing zone, at which very small air bubbles are formed. The rising speed of the bubbles is so low that the degree of utilization of oxygen in the added air is above 20 %. An arrangement for addition of air in highly viscous substrate comprises a tube (1) for addition of air to a rotating foam forming means (2) which is submerged in the substrate in a fermentation tank. The means comprises two elements where at least one of the elements has a side with a structure with lowered and/or raised parts. The elements are arranged to be movable in a transversal way in relation to each other with a mutual distance corresponding to the desired size of the liquid lamella. The spaces which are present in the lowered parts in the structure are connected to the tube for addition of air and surrounding substrate.
