Abstract: An air drier arrangement including an air compressor (1), an air-drier (3) and air conduits (2, 4). In order to obtain favorable working conditions for the arrangement under different temperatures there is a switch-over valve (6) in a separate signal air pipe (5) from the air drier to the compressor. This valve is operable between a first position, giving a governor mode for the arrangement, and a second position, giving an unloader mode for the arrangement. The operations of the valve may be governed by a thermostat (9).

Abstract: An inlet valve for an air drier between an inlet (35) from a compressor and an inlet bore (32) comprises an axially movable valve element (31), a spring (34) for biasing the valve element into a closing position against a seat (30'), and a valve element shoulder (31'), on which the pressure in the inlet is arranged to act in a valve opening direction. A sealing on the shoulder is in the form of a U-sealing (36) allowing air under pressure admitted to the underside of the valve element for urging the latter in a valve closing direction to pass by the sealing to the inlet but preventing flow in the opposite direction.

Abstract: Porous material of a polysaccharide and a method for preparations of such a material, wherein a water-based solution of the polysaccharide is mixed, with controlled stirring, with an essentially water-immiscible organic phase to form an emulsion, which when allowed to solidify, just before or during the gelling process, forms a network of two continuous phases, an aqueous polysaccharide phase and a flow-pore-forming organic phase, resulting in a material with two types of pores: small diameter diffusion pores and large diameter flow through pores.

Abstract: The present invention comprises a method Of detecting and quantifying components separated by capillary electrophoresis or other techniques using thin capillaries in the separation. The method of the present invention comprises irradiating the whole or large parts of the capillary at short time intervals and detecting the fluorescence originating from the sample components, preferably by a CCD detector (charge coupled device). Thereby, an instantaneous image of the progress of the separation process is obtained. The present invention further comprises an apparatus for performing this detection.

Abstract: A retarding valve at a single-tower air drier for obtaining a controlled time for the flow of regenerating air from an air tank to a desiccant cartridge has a movable valve stem (7), which is provided with a piston (14) having a slightly smaller diameter than a chamber (13), in which it is movable in hydraulic oil (15), so that a narrow circumferential slit for the oil is formed. The valve stem with its piston is biased by a spring (16) from a position--at the beginning of each regenerating cycle--permitting flow through the valve to a position closing off flow through the valve.

Abstract: A brake block holder arrangement comprises a brake block holder (7) receiving a brake force from an axially movable push rod (2) of a brake actuator (1) and being pivotally attached to brake block hangers (5), which are suspended from a suspension bracket (4) on the actuator. A push rod head (3) on the push rod is in direct contact with a generally tube-shaped portion of the brake block holder around its shaft (8) for pivotal connection to the hangers. For accomplishing guiding and torque transmission the push rod head has extensions (11, 12) with a width corresponding to the distance between the side-walls (7') of the brake block holder, one of the extensions being provided with a laterally movable cross piece (19) for toothed engagement with rotatable segments (16) in the inner surfaces of the side-walls.

Abstract: Methods for coating hydrophilic gels onto the surface of solid particles are disclosed which include utilizing hydrophilic solid particles, intimately admixing these hydrophilic solid particles with a hydrophilic gel-forming substance at a temperature above the gelling temperature so as to coat the solid hydrophilic particles, and then separating these coated particles from each other and cooling them to a temperature below the gelling temperature. The use of these coated particles is also disclosed in connection with various separation processes, such as an ion exchanger, in those cases where the gel-forming substance contains charged groups, or providing the particles with suitable adsorbent groups.

Abstract: In a method for the firm bonding at elevated temperatures of thin, large-area wafers of different thermal expansion the deformations of the laminar bond occurring later during cooling are at least partially compensated by an appropriate pre-deformation in the opposite direction. An apparatus for conducting the method uses the different thermal expansion of a housing (1) and a ring-shaped thermal expansion element (3) to produce the pre-deformation.

Abstract: A motor-driven truck of the type comprising a front lifting stand, first guide and journalling elements including a longitudinal stand stationary mounted on the chassis, second guide and journalling elements including a stand movable along the stationary stand, and an operator's cab supported by the movable stand and arranged to be placed in a desired position which is variable with respect to the stationary stand and to the front lifting stand as well, said first guide and journalling elements are firmly connected to the movable stand and guided by the stationary stand. The stationary stand is diagonally arranged so that it encompasses an acute angle .alpha. with the center line C.sub.1 of the truck and so that it extends between a rear place at the center line C.sub.

Abstract: A drying tower for a compressed air drier includes a base (5) and a reservoir (4) containing a cartridge (8) filled with filter material (12) and desiccant (11).In order to obtain an optimal utilization of the desiccant and of the space the cartridge (8) completely fills the reservoir (4) and is provided with two longitudinal partition walls (13, 14) perpendicular to each other and having two openings (15) at the end remote from the base, so that--aided by suitable shaping of the base--the air will be transported in a winding path consecutively through all four desiccant-filled compartments formed by the walls.

Abstract: A fastening device (14) consisting of a plate bent to form what is essentially a U profile. The shanks (32) of this plate each comprise a narrow section (34), the end of which widens to form a pair of hooks (36, 38). The hooks are provided in order to allow attachment of the device to a vertical supporting rail (12) through the introduction of the shanks into corresponding parallel slots (20) in the rail, by which means a corresponding mounting device (26) on a screen or wall panel (10) can be hooked in between the rail (12) and the rib (30) of the fastening device itself. In order to prevent the fastening device from coming loose and falling out when a screen or wall panel is removed, at least one hook (36) of each shank (32) is provided with a projection (40) directed towards the rib of the fastening device.
