Abstract: The present invention relates briefly to an arrangement for hoisting devices to keep a cable (10) substantially vertically stretched between a derrick or the like and a hoisting device, e.g. a derrick bridle (1), so that the cable will not be able to be depositioned by gusts and other factors. The arrangement includes a set of brackets (12) stretched between and glidably fixed to two opposed hoisting cords (2a, 4a), each bracket (12) being equipped with a ring (13) approximately center, through which ring the cable (10) runs with an increasing inner diameter for each ring (13) from the top downwards. To the cable (10) are fastened a set of elements (14) spaced apart with increasing diameter for each element from the top downwards for each inner diameter of the rings (13) so that each element (14) one by one is restricted to pass a corresponding ring (13) and thereby each hoists one by one a bracket (12) holding the cable (10).

Abstract: Rhizobia transformants that nodulate and fix nitrogen in non-legumes. The nodulated non-legume plants can be grown without nitrogenous fertilizer and have at least the same or higher protein content, dry matter content and nitrogen content than their non-nodulated counterparts which are fertilized by the addition of nitrogenous fertilizer. The straw remaining after harvesting the nodulated non-legumes is also high in protein content.

Abstract: The release of a moulded concrete body from the mould can be improved by applying, to the mould, an effective amount of a concrete release composition in the form of an oil-in-water emulsion in which the oily phase is at least one of the following: a mineral oil with a content of aromatics of at most 9%, a vegetable oil and one or more oily esters of aliphatic carboxylic acids with mono- or dihydric alcohols and having a melting point of at the most 35.degree. C., the total number of carbon atoms in the esters being 8-46, and comprising one or more non-ionic surfactants in an amount of 0.5-20% by weight and one or more anionic surfactants in an amount of 1-100%, based on the non-ionic surfactant. The emulsion may also comprise cationic surfactants, anti-freeze, stabilizers, corrosion inhibitors, etc. The oily esters of aliphatic carboxylic acids with mono- or dihydric alcohols may also be used in non-emulsified form.

Abstract: A pesticidal concentrate comprising a pesticidal component suspended in an oily component, the composition comprising 1-55% by weight of pesticide, 20-90% by weight of the oily component and 1-45% by weight of a surfactant component, and optionally water and optionally filler, the surfactant component comprising one or more stabilizing constituents comprising a C.sub.5-30 hydrocarbylene chain carrying a group capable of forming hydrogen bonds with water, and optionally one or more other constituents selected from the group consisting of non-ionic and ionic surfactants, the stabilizing constituent being present in an amount of at least 4% by weight, calculated on the total amount of surfactant component in the composition.Examples of stabilizing constituents are fatty alcohols and amino group-containing surfactants, especially ampholytes.

Abstract: A yawing system for a wind mill consists of two yawing motors (9, 11) acting on a toothed rim of the yawing bearing. On each its drive shaft (21) the motors (9, 11) are provided with a free wheel (23) and an electromagnetic friction brake (25). The free wheel devices (23) are directed opposite each other. A control system operates in a passive state in such a manner that the motors give opposite and relative to the braking moment of the brake (25) of a second motor smaller torque thereby avoiding dead clearance between drive wheel (15) and toothed rim (17) while at the same time keeping the generator housing (5) of the mill at rest. In the active state of the control system both brakes (25) are disengaged and both motors give a higher torque in the same direction. The system acts as a shock absorber by loads exceeding the fixed slip moment of the friction brake (25).

Abstract: A windmill is provided with a yawing device which includes two or more gear motors disposed about the periphery of a stationary tower toothed rim. Each gear motor has a driving wheel attached at an end thereof for engaging the toothed rim. By applying a suitable current to the gear motors, in equal and opposite directions, the mill can be held at an optimum position, relative to the wind, at a low power consumption. The use of multiple motors also provides optimum reliability with smooth and even yawing action.

Abstract: A safety mat for protection against erosion and/or undermining consisting of a number of parallel tubular members containing a filling material and being interconnected by cross-binding ribbons placed at right angles to the tubular members. As filling material is used a granulated material of an average density of at least 1.6 Kg/dm.sup.3, and the tubular members have a degree of filling of substantially 75%. Using a relatively heavy filling material that is introduced relatively loosely a mat is obtained having great flexibility, being able, therefore, to lie close up against even a domed bottom.

Abstract: To mix a gas with a mass flowing continuously through a conduit, the gas is caused to flow from a pressurized gas supply into the conduit by way of a nozzle in which the gas expands at a critical pressure ratio; and the pressure of the gas flowing from the nozzle is increased before the gas is introduced into the flowing mass.

Abstract: A method and an apparatus for determining the relative air or gas content in a product flowing through a conduit. By means of two substantially synchronized pistons moving in opposed cylinders, a sample of the product is transferred from the conduit to a sampling chamber defined in one of the cylinders between the pistons. After the sample has been isolated from the material flowing through the conduit, the pistons are moved towards one another whereby the volume of the sampling chamber is reduced to a predetermined value. The compression of the sample results in an increased pressure, and when the pressure has reached a predetermined value, an overflow valve is opened to let excess material flow from the sampling chamber back to the conduit. When the movement of the pistons towards one another has stopped and said predetermined pressure has been established in the sample, a predetermined expansion of the sample is effected by moving the pistons a predetermined distance from one another.
