The invention relates to a method and to a corresponding system for controlling energy streams in order to connect operations of an electricity distribution network () and a heat distribution network () by means of an intermediate energy storage unit (). According to the invention, the power balance and quality of current and voltage of the electricity distribution network () are adjusted by supplying the losses provided by adjustment of the electricity distribution network to the energy storage unit () in the form of heat, and from the energy storage unit the heat is extracted to the heat distribution network () according to the heat requirement of the heat distribution network.

Method and system for controlling energy streams

The invention relates to a method and to an apparatus for separating and utilizing carbon dioxide. According to the invention, carbon dioxide () is separated from air () being conducted to a building and/or from air () being circulated in the building to reduce the level of carbon dioxide in indoor air () of the building (), the carbon dioxide () is recovered, and the carbon dioxide is conducted to a carbon dioxide treatment stage (), where a chemical compound () is formed from the carbon dioxide. In addition, the invention relates to the use of the method.

The invention relates to a joint between a copper short-circuiting ring () and a copper bar () of the damper winding in a permanent magnet synchronous machine, wherein the end of the bar is jointed to a hole () disposed in the short-circuiting ring by welding them together at the mating surfaces. Further, the invention relates to a corresponding method. According to the invention the short-circuiting ring () includes a blocking structure for limiting the heat flux from being conducted further into the short-circuiting ring from the weld between the short-circuiting ring and the bar.

A reuse method for utilising reject rolls being produced in paper and cardboard factories, wherein from the reject rolls () there are made straight roll cores () having the same size in their inner and external diameter and varying in length, the straight roll cores being defined by the width of each reject roll (); the straight roll cores are joined end-to-end to form a long, continuous core tube (), and the core tube is cut to size to form roll cores () of paper and cardboard industry.

Reuse method for utilising reject rolls being produced in paper and cardboard factories

The present invention relates to a method for manufacturing a formed piece of aluminum or some other relatively soft metal. In accordance with the invention, a slice is cut form a rod of aluminum or some other raw-cast metal; the slice forms a blank (,), which is placed on the mould surface (,) of a mould tool (,) rotating about its axis (,), and which is formed using a roll forming tool rotating about its axis (,) inclined to the axis of the mould tool and being in linear rolling contact with the blank surface. The blank is then formed to a substantially disc-shaped piece of plate between the opposite rotating tools (,). The method may be part of the manufacturing process of a frying pan or kettle so that the roll formed piece may comprise the bottom and collar of the utensil, which is bent to form the sides of the cooking utensil at the next pressure turning stage; or, alternatively, the roll formed piece may be fastened as the bottom to a separately manufactured utensil by linear pressing. The formed piece may also be deep-drawn to a globe of a street light, or it may be used as a traffic sign, or as a lid for a soft-drink can.

Method for manufacturing a formed piece of metal

A process and apparatus for the manufacture of a cooking vessel, such as a frying pan (12) or a kettle from a metal blank. The vessel is manufactured by roll forming techniques by using a lower tool (3) that rotates around its axis (2), the form face (6, 7) of the lower tool being designed so that it corresponds to the outer surface of the thus created vessel, and an upper tool (5) that rotates around its axis (4), the surface (9, 10) of the upper tool having a profile that corresponds to the inner surface formed to the vessel. The blank is placed on the form face of the lower tool and the tools (3, 5) are then made to rotate so that the blank rotates along with the lower tool (3), and the surface of the upper tool (5) is in linear roll contact with the blank, whereby the metal is formed in the slot between the tools, spreading out into the desired form of the vessel. A vertical wall on the lower tool adjacent the blank may prevent the blank from becoming dislocated on the lower tool. First, a pressure sufficient to give the blank substantially the desired form of the cooking vessel is applied. Thereafter, the pressure is reduced to finish the surfaces of the cooking vessel. In the manufacture of the frying pan (12), the blank may be a straight piece of sheet, whereby the rising sides of the pan are formed in the roll forming with the blank spreading radially outwards at its edges. In connection with the forming, the outer and inner surface of the vessel can be provided with patterns consisting of protrusions and/or recesses.
