The apparatus comprises a biorotor (2) preferably formed by a sector modules (20), within which biorotor a granular medium (11) is provided to form a substrate for the biomass, said medium simultaneously serving as a hydraulic bearing during the rotation of the rotor partly immersed in water so that it holds up the entire biorotor structure as well as the active biomass.

Toptical compsn. comprises (1) at least one topically-active pharmaceutical (I) and (2) hyaluronic acid (II), or one of its mol. fractions, opt. in the form of a salt with alkali or alkaline eart metals, Al, NH4 or with one or more active ingredients (esp. (I)). The pure Ba salts (A) of noninflammatory (II) fractions of mol.wts. 250000-350000; 50000-100000 or 500000-730000, free of (II) of mol.wt....

Solid phase system for use in a ligand-receptor assay for the detection of a selected analyte in a fluid sample comprises a porous matrix in which microspheres are entrapped, the microspheres being bound with a receptor capable of capturing a target ligand. The system is for use in a multiple ligand-receptor assay for simultaneous detection of at least two selected analytes, distinct gps. of micro...

The connection between an internally threaded end (12) and the externally threaded end (13) of two members forming an impact operated rock drill spindle, uses threads with straight flanks (20). Between the roots of the external threads and the crests of the internal threads is a gap (a) larger than 1% of the outside dia. (Dy) of the external threads. This gap is at least four times the size of the...

A method for increasing bone mass in a human afflicted with osteoporosis or a similar disease which comprises administering to the human so afflicted an effective amount of a composition comprising a parathyroid hormone or physiologically active fragment thereof, or equivalents thereof, in combination with either (a) a hydroxylated Vitamin D compound, or a structual or functional analogue thereof,...

The hand grip lock arrangement, when the hand grip (5) is moved in one direction, pre-locks the lid (2) of the case (1). Movement in the other direction releases the lid. The pre-locking position is maintained with specific force by a spring-loaded ball which adopts a stop position between the hand grip and the case. - For definite locking, a 'police lock' immovably connects the hand grip, case an...

The mat has a metal frame (1-4), e.g. of aluminium, which before assembly is enclosable in an easily carriable package. Once the framework has been assembled, the floor parts are fitted inside it.

The electric boiler heater (2) has an outgoing conduit (8,13) to the boiler and radiator circuits, also a return conduit (7,16) from them. A valve device (11,12), where required, maintains only the radiator circuit connected to the electric boiler heater.

The present invention relates to a new type of digitally controlled light chopper for acting on one or more independent channels of optical measurement or communication signals. This arrangement for acting on light comprises one or more chopper blade(s) mounted in a chopper housing with a fixed part and a movable part on spindles of step motors. The chopper blades have a number of holes which can ...

A method for the impregnation of wood to prevent attack by harmful agents such as decay fungi or mould fungi and bacteria by the application of an aqueous solution of an alkali lignin modified into a water-soluble form. Impregnation takes place in two stages, these being an initial stage in which the aqueous solution containing the lignin still in its water-soluble form and with a pH not exceeding...

Electrochemical corrosion protection of metal surfaces. The anode has the anode material mechanically fixed to a permanent magnet. The side of the arrangement which has the magnet is placed next to the surface which it is to protect. It is held there by the magnetic force.

An adjustment mechanism is coupled to a regulating motor with a circuit provided incorporating a light ingress monitor and a number of operational amplifiers. One of these is connected to amplify a signal from the monitor, and the other is connected as a comparator. Two of the amplifiers are connected as drive circuits for the motor. A toggle circuit is connected between the comparison circuit and...

The invention concerns a method and a device for installation of a mixer in a liquid tank. The mixer is brought downwards into the tank along a guide which is pivotally attached in the upper part of the tank. During operation the reaction force from the impeller will course the guide to pivot making the mixer to take support against the tank wall.
