Abstract: Lifting gear, for example for a fork-lift truck, comprises upper and lower telescoping mast assemblies (4, 3) which are displaceable relatively to each other by hydraulic lifting means to raise and lower a lifting carriage through the intermediary of a pulley/ chain mechanism (23, 2). Each mast assembly comprises two upwardly extending members (5 or 12) which are interconnected, by members (13), or (7) and (8), at the ends away from the other mast assembly. This leaves the central part of the mast assembly unobstructed, providing good visibility to an operator. Visibility is also enhanced by forming the members (5) of the lower assembly (3) with cylindrical portions (10), (Figure 6) which accommodate the lifting means. <IMAGE>

Abstract: A method of operating an electric arc furnace is disclosed by which an arc electrode provided in an electric arc furnace is supplied with electric power, an electric arc is extended from the arc electrode and raw material in the electric arc furnace is molten by the arc. Before operation of the electric arc furnace, an electric current I satisfying an equation d[Pi/(Pi-Pl-ql)]dI=0 is first calculated where Pi is the secondary output of the used arc furnace transformer. Pl is the total ohmic loss of the secondary winding of the transformer and of an electric circuit connecting the secondary of the transformer with the arc electrode, ql is the heat loss of the used electric arc furnace and I is the electric current flowing from the secondary of the transformer to the arc electrode. Next, when electric power is really supplied to the arc electrode from the arc furnace transformer to operate the electric arc furnace, the beforehand obtained electric current is supplied to the arc electrode from the transformer. As a result, the specific electric power consumption can be minimized.

Abstract: Panel intended primarily for floor structures. To achieve a high degree of impact sound insulation, elastic panels are required under the floor layer, while at the same time the compression of the panel under high loads must be limited. From the acoustic point of view, the panel must be sound-absorbing. These requirements are achieved using a panel which has a core 1 of elastic and sound- absorbing material and a two-part perforated shell 2, 3 around the latter. Under normal loading, the two parts of the shell are disengaged and the elastic properties of the core provide a high degree of insulation. In the event of high loads, the legs of one part of the shell contact the other, and further compression is stopped. <IMAGE>

Abstract: The present invention relates to a method and a device for executing phase compensation in a control system of a motor-driven vehicle, in which the time derivative for an output signal (y) from a circuit (1) contained in the control system is limited relative to the time derivative for an input signal (u) to the circuit (1) if the time derivative for the input signal (u) exceeds a predetermined value. A difference signal ( epsilon ) is formed between the output signal (y) and a signal (x) present in the circuit (1), the time derivative of which is not limited in relation to the time derivative for the input signal (u). The difference signal ( epsilon ) is filtered via an asymptotically stable filter (3) to form a signal ( delta ), which is fed back and added to the input signal (u) of the circuit (1) to form the signal (x). A conventional rate limiter may be used to form the output signal (y) from the signal (x).

Date May 2, 1996In joining an optical fiber containing twin cores to a corresponding optical fiber of standard type having a single core and having the same outer diameter, so that a core in the twin-core fiber is aligned with the core in the standard fiber, a conventional automatic splicing machine for optical fibers is used. The twin-core fiber is placed with its cores for instance located in a vertical plane. Then the fibers are spliced in a conventional manner with an alignment of the outer surfaces of the fiber ends and during the splicing procedure or from the finished splice the lateral offset of for instance the upper core of the twin-core fiber and the single core is determined. This can be carried out by capturing an image of the fiber splice in a heated state, when the splice is performed by fusion-welding. The determined offset value then gives the offset, which is to exist between the outer surfaces of the fiber ends for providing the correct alignment of the fiber cores. Hence, the splice region of the fibers is then removed and the fibers are spliced again, but this time with a suitable, calculated offset of the outer surfaces of the fibers.
