The implant (13) comprises an optic part (14) consisting essentially of a divergent lens with thick edges (16) and a haptic part comprising two elastic loops (15) for support inside the eye and extending on both sides of the optic part, in the same diametral direction (50), from two points on the optic part which are respectively and diametrally opposed. A connection zone (19) situated outside the...

A fermentation process and a fermenter in which aeration is improved by injecting substantially pure oxygen into a culture medium by means including a venturi (14) located outside the main body of the fermenter. Preferably the oxygen is injected at the throat of the venturi. The invention is particularly suitable for the fermentation of viscous cultures, e.g. cultures of filamentous fungi.

The wind and heat driven power unit is suitable for dwelling places, and also involved is a water power unit which does not require a reservoir, but with a water condenser, and is usable as a waterborne craft.

An electrochemical cell [1] comprising a negative electrode [6] whose electrochemically active material includes an intermetallic compound which can form a hydride with hydrogen, the cell comprising an electrolyte of a solution of at least one alkali hydroxide in water, the negative electrode being provided with a discharge buffer by introducing a quantity of an alkali metal [11], alkaline earth m...

The rotor (12) is driven by the air current, its speed having a linear connection with the amt. of air passing through the chamber. The flow chamber is formed by a tubular casing (10) in one end of which, forming the air flow inlet, is a distributor arrangement (24) with several small straight channels filling out the whole cross-section of the casing. The incoming air current is laminar when it l...

Laminate comprises at least two material layers. At least one of these is a liquid permeable nonwoven layer combined with at least one thermoplastic layer. The layers pass through a suction or vacuum arrangement for physical treatment of the liquid permeable layer. The thermoplastic layer is softened and made to penetrate (and be anchored in) the liquid permeable layer. The thickness of the thermo...

The arrangement comprises a vessel for the liquid, a conveyor (8) to move the slices through the treatment vessel (16) and an arrangement to increase the contact between the slices and the liquid. The arrangement is designed to give strong turbulence between the liquid and the slices i.e. strong relative motion.

In this method, preferably unbleached paper is sized and sand putty mixed in clear wallpaper paste is thereafter applied at least twice, with intermediate drying.

The invention relates to a folding plastic sheet having a folding notch or joint 2 which extends between opposite ends of the sheet. The sheet can be folded in only one direction in the joint to form a blunt folding edge. In the joint there is a string-shaped reinforcement 3, which is turned outwards when the sheet is folded in the joint and which reinforcement is joined to the material of the pla...

A device for particle radiation of objects or spaces comprises two ring-shaped coaxially arranged magnets 12,20 which are arranged to generate magnetic fields in a vacuum tank. The inner magnet 20 generates a homogenous field perpendicular to the place in which charged particles are intended to circulate and the outer magnet 12,14 generates a non-homogenous field which decreases radially outwards ...
