摘要： According to a method for applying an insulating layer to a surface fibers, of an inorganic material an sprayed onto the surface under simultaneous wetting of the fibers with water and/or a binder so that the fibers stick to the surface whereafter the layer is formed and dryed/hardened. Prior to or after the drying/hardening a binder can be sprayed to the surface for the purpose of achieving a dustless and mechanically resistant surface layer. A device for applying of an insulation to a surface of an object (10), making use of the method, comprises a store (41) of fibers of an inorganic material, a conduit (20) for the transfer fibers from the store (41) to a spray nozzle (21) and device for generating an air flow in the conduit (20) directed towards the nozzle (21). Further, the device includes a first ejector (22) provided at the end of the conduit facing the store (41) for introducing air jets into the conduit (20) in the direction of the fiber stream but at an inclination with respect to the stream, a second ejector (23) disposed at the end of the conduit facing the spray nozzle (21) for the introduction of air jets directed so as to bring the fiber stream into rotation, and a device (24) disposed adjacent to the spray nozzle (21) for introducing into the fiber stream, but outside of the spray nozzle, of liquid jets in the direction of the fiber stream but forming an angle with the stream, the liquid jets comprising a mixture of water and a binder.

摘要： An arm preferably for electric switches, the arm being controlled by electricity, and having a first fixed end the other end of which is movable perpendicular to the length direction of the arm. The arm comprises two parallel portions (47) separated by an air gap (17) or some other heat insulating material, and which are secured to each other at each end. At least one of the portions, being heated by electricity and, through longitudinal differential expansion with respect to the other portion, achieves said movement. The portions are so shaped that, adjacent the fixed end (at 45) with respect to the rest of the portions, they have a reduced bending resistance about an axis which is perpendicular to the length direction of the arm and with respect to said direction of movement.

摘要： A relay including a control circuit which via a movement creating or actuating arm and a transmission mechanism activates a contact means in order to switch on or switch off a main circuit. The actuating arm includes two elongated parallel parts which are separated by a thermally and electrically insulated layer. The two parallel parts each have a first end fastened to a housing or holder. The two parallel parts each have a second end fixed to each other, forming a movable end of the arm. One or both parallel parts of the arm are provided with a heat creating or producing element. The actuating arm, attached at one end and movable at the other end, together with the heat producing element, constitutes the first part of the control circuit or relay. When a control current flows through the heat producing element, one of the two parallel parts of the arm is heated thereby causing a movement of the movable end of the arm to thereby activate the control means through the transmission mechanism. The transmission mechanism includes a finger extending mainly perpendicular to the length direction of the movable arm, with the finger acting on a leaf spring. The leaf spring is generally parallel to the arm, the spring supports said contact means which switch on or off the main circuit.
