Title: Joint arrangement for jointing together two metal shapes
Inventor: TOENSMANN ARMIN
IPC: E06B3/96
Filed: 1994-02-28
Abstract: A frame profile (1) and a bar profile (2) are connected to one another via two T-connectors (4 and 7) which are fixed on the frame profile (1). Resulting in the joint region is a gap which, according to the invention, is sealed by a sealing cushion (13) fixed on the frame profile (1). The sealing cushion (13) consists of an elastic material, preferably of closed-cell foam. The thickness of the sealing cushion (13) is greater than the gap width, with the result that, after frame profile (1) and bar profile (2) have been fitted together, the sealing cushion (13) is compressed by the bar profile (2) and is pressed firmly onto the frame profile (1). Sealing of the gap region by a sealing cushion (13) can be carried out easily and requires only a low degree of material outlay. <IMAGE>

Title: Reduction in the noise produced by a rotor blade of a wind turbine
Inventor: WOBBEN ALOYS
IPC: F01D25/02
Filed: 1999-12-09
Abstract: Different shapes of rotor blades for wind energy plants are known. In a wind energy plant the rotors and more particularly their blades are the main source of noise. To improve acceptance of wind energy and comply with noise reduction legislation the aim is to work towards keeping noise emissions as low as possible, especially since wind energy plants are often set up near residential areas. The noise at present emitted by wind energy plants or wind energy conversion systems also means that they meet with resistance from sectors of the population. As a result, such plants are sometimes difficult or even impossible to install since, owing to the applicable environmental protection standards and the fact that noise too is considered a form of environmental pollution, the authorities refuse permission for wind energy plants. The aim of the invention is therefore to further reduce the noise emissions of wind energy plants. To this end the invention provides for a rotor blade to have means for reducing a noise emitted by such a blade, said means being embodied by a liquid-repellent layer and/or surface which is configured on at least a partial surface of the rotor blade.

At least one shank (3) is formed transverse to the cover on the inner edge of the lip, which has, on the outer side of its lower free end, an outward pointing wedge-shaped section, preferably with a tapered longitudinal profile. In a working position, the shank engages with the collar (12) by means of said section in an interference fit and/or the cover and collar are coupled to each other via screw connections.

Title: Method and mould shooter for producing mould parts, such as casting cores, for casting moulds used to cast metal melts
Inventor: STAUDER BERNHARD
IPC: B22C15/24
Filed: 2002-09-09
Abstract: The invention relates to a method for the manufacture of mould parts, in particular of casting cores, for casting moulds for the casting of molten metal heats, wherein, in a shoot-moulding machine (1), with the aid of filling elements, such as shooting nozzles (8) and a shooting hood (6), material mould (F) containing an inorganic binding agent is filled into a cavity (12) of a mould tool (10) which determines the shape of the mould part (K) which is to be manufactured, wherein, heat is supplied to the mould material (F) filled into the mould tool (10), over a hardening period, in order for the mould material (F) to solidify due to the extraction of moisture, and wherein, during the hardening period, at least the filling elements (6,8) of the shoot-moulding machine (1), which contains mould material (F), and which are in a stand-by position during this hardening period, and are heated concomitantly by the radiant heat emitted by the mould tool (10), are kept at a moisture content level which prevents the solidifying of the mould material (F). In this way, mould parts for casting moulds can be manufactured reliably and with reduced defect incidence from a mould material containing an inorganic binding agent.
