Abstract: A horse-shoe made of synthetic material, preferably polyurethane plastic (PUR), having a bottom ground face (2), an upper hoof face (3), and a number of nail holes (7) for passing of horse-shoe nails. The horse-shoe has a sectional profile comprising two or more up-right members running side by side in the arcuate length of the horse-shoe, the members connecting said ground and hoof faces. At least one of said members (10) in a vertical plane having a vertical dimension substantially greater than a horizontal dimension of the member such that a length (1) of the member is at least 1.5 times a width (w) thereof in said vertical plane, and stiffening walls (12) arranged in the hoof face (3) between the up-right members of the sectional profile.

Abstract: The invention concerns a method of providing a coating having a predetermined hardness on a substrate comprising the steps of

Abstract: The present invention concerns the use of a pre-alloyed atomised powder in combination with at least one melting electrode wire in the SAW method. The electrode wire is an unalloyed or low-alloy metal wire and the metal powder is a metal powder containing a higher percentage of alloying elements than the electrode wire.

Abstract: A vacuum unit, intended particularly for a vacuum toilet system, includes two valves (4, 6) which can be connected to a compressed-air source, an ejector (10) which includes an inlet nozzle (10a), an outlet nozzle (10b) and a vacuum opening (10c). The ejector is connected to the first valve (4) via the inlet nozzle, and to a first vacuum-unit connection (U1), via the vacuum opening. A piston valve (16) includes a first inlet (16a), a second inlet (16b) and an outlet (16c). The first inlet connects the piston valve with the ejector outlet nozzle (10), the second inlet connects the piston valve with the second valve (6), and the outlet connects the piston valve with a second vacuum-unit connection (U2). A check valve (17) is mounted between the piston valve outlet (16c) and the second vacuum-unit connection (U2). A passageway connects the second valve (6) and the second inlet (16b) of the piston valve with a further ejector inlet (10d).

Abstract: The invention relates to shot pellets for hunting in wet marshlands or corresponding wet areas. The shot has an inner core of copper or copper alloy and an outer layer of silver or silver alloy. No heavy metal will leach from the shot into the environmental surroundings, and the shot has no toxic effect on birds, even should they ingest a considerable quantity of shot. The shot is produced by granulating copper or copper alloy electrochemically to obtain shot cores, whereafter at least one layer is applied thereto. The outer layer always consists of silver or a silver alloy.

Abstract: The invention relates to shot pellets for hunting wild game, particularly birds on wet marshlands. The pellets are also suitable for clay pigeon shooting on organized skeet ranges. The shot pellets have an inner core comprised of lead or lead alloy, and an outer layer of silver or silver alloy. The shot pellets are not influenced, or only slightly influenced by a strong hydrochloric acid environment, therewith greatly eliminating the risk of lead leaching from the pellets. The shot pellets are produced by coating shot pellet cores of lead or lead alloy electrochemically with at least one layer, wherein the outermost layer is always comprised of silver or a silver alloy.

Abstract: A lining element for pulp refiners is made by casting from a steel alloy containing from 1.0 to 5 percent by weight of titanium present as titanium carbide grains having an average size of 10 microns or less and being uniformly distributed throughout the lining element. The titanium carbide prevents polishing of the working faces of the lining element.
