摘要： The invention is related to a method for joining two or more metal parts (1, 2) together. According to the invention, the joining is carried out by using roll forming techniques by placing the metal parts (1, 2) on top of each other on the form face (7) of a tool (4) which is made to rotate, and by arranging the topmost part (1) in linear roll contact with a forming tool (6) which is also in rotational movement, whereby the malleable deformation of the metal in the slot between the tools integrates the parts together. A mesh or perforated plate (2) of harder metal in particular can be joined to the sheet-like part (1) of a softer metal by using roll forming, by making the metal ingredient of the latter to penetrate the apertures (12) in the former. The invention can be applied in the manufacture of frying pans or other cooking vessels which are provided with induction-heated bottoms by joining, for example, a magnetic steel mesh or perforated plate to the bottom of a vessel made of aluminium, as part of the forming of an aluminium blank into the form of a vessel by using roll forming.

摘要： A measuring procedure and a flowmeter for the measurement of liquid flow in a hole bored in the ground, such as rock. The flowmeter consists of a long cylindrical body comprising: ring-shaped sealing elements (5) placed at a distance from each other in the longitudinal direction to seal off a certain volumetric section from the rest of the hole; dividing elements (6) for dividing the volumetric section into at least three sectors (1) extending from one sealing element to the other; flow ducts (2) interconnecting the sectors; an impulse source (3) placed at the junction of the flow ducts; and sensors (4) placed in the flow ducts for measuring the magnitudes and velocities of currents between sectors by monitoring the velocity and direction of motion of an impulse.

摘要： Flowmeter for locating zones containing currents in a bore hole made in a rock. The flowmeter comprises parting elements (1) for separating a measurement section (3) in the hole from the rest of the hole in a substantially pressure-tight manner; an open flow duct (4) forming a free flow link between the hole portions on opposite sides of the flowmeter past the measurement section; and a measuring duct (5) leading from the section under measurement to a point outside it, together with measuring equipment (6), for measuring the magnitude and direction of flow between the measurement section and the hole portion outside it.

摘要： The present invention relates to a method for manufacturing a formed piece of aluminium or some other relatively soft metal. In accordance with the invention, a slice is cut from a rod of aluminium or some other raw-cast metal; the slice forms a blank (3), which is placed on the mould surface (10) of a mould tool (5) rotating about its axis (4), and which is formed using a roll forming tool rotating about its axis (6) 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 (5, 7). 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 rol 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.

摘要： Procedure for the monitoring of large surface areas, in which procedure the area (10) to be monitored is observed by means of a monitoring unit (14) comprising a thermal camera (2) and an electromagnetic radar (3), which are rotated about a vertical shaft to scan the area to be monitored in a horizontal plane, and a processing device (13) for the processing of the data provided by the thermal camera and the radar. In the procedure, the surface area (10) to be monitored is divided into surface elements (12) as a function of the angle of rotation of the vertical shaft and the scanning distance, and monitoring criteria are defined for the surface elements; movements in the surface area to be monitored are observed by means of the electromagnetic radar (3); objects (1) differing from their surroundings in respect of temperature are searched by means of the thermal camera (2); and the location of the object, i.e. the surface element corresponding to the object, is determined and the object is identified by means of either the radar or the thermal camera, depending on the conditions and the distance of observation.

摘要： Procedure for cleaning the middle cylinder of a press, in which procedure wash fluid (2) is applied to the surface of the middle cylinder (1) to be cleaned and the middle cylinder is rotated while at the same time limiting the speed of the paper running around it so as to produce a speed difference between the circumferential velocity of the middle cylinder and the running velocity of the paper, producing abrasion between the paper and the surface of the middle cylinder to remove dirt from it. The motion of the paper (3) is prevented during cleaning by pressing it against the middle cylinder (1).
