Abstract: A hand tool for providing an optical fibre with an end face which is flat and lies in a plane radial to the fibre axis comprises four elongate members (1,2,3,4) extending side by side. The first member (1) is of tubular form and surrounds the other three members (2,3,4) and has, mounted near one of its ends, jaws of two pairs of jaws (16,17) transversely spaced on opposite sides of the longitudinal axis of the member (1) and, between the jaws (16,17), a table having a curved surface. The second member (2) is pivotally connected to the first member (1) at its end remote from the table (6) about an axis extending transversely of the members, is urged away from an internal surface of the first member (1) by a leaf spring and carries, near its other end, the other jaws of the transversely spaced pairs of jaws. The jaws of one pair of jaws (16,17) are so resiliently mounted on the first (1) and second (2) members that, when the jaws (16,17) move towards one another to grip an optical fibre between them, the parts of the jaws (16,17) in contact with the fibre will tend to move away from the table (6) and from the other pair of jaws (16,17) to exert a tensile force on the fibre. The third member (3) is pivotally connected to the first member (1) at its end remote from the table about an axis extending transversely of the members, is urged away from the first member by the leaf spring and carries near its other end an elongate cutter. The fourth member (4) is pivotally connected at one of its ends to the first member (1) and is so shaped intermediate of its ends that, when it is caused to pivot towards the third (3) and second (2) members an intermediate part bears against the third member (3) to cause the third (3) and second (2) members to pivot against the action of the leaf spring and so cause the jaws of the pairs of jaws (16,17) to grip an optical fibre positioned between them and to cause the cutting edge of the cutter to contact and move transversely across the tensioned optical fibre to score the fibre to such an extent that the fibre breaks to form end faces of the fibre that are flat and lie in planes radial to the axis of the fibre.

Abstract: A method for continuously producing a powder-filled tubular welding electrode, whereby a metallic band while being fed is formed to a gutter (16) and thereupon to a tube 121), whereby the edges of the gutter are welded together and welding powder is supplied via a conduit (18, 19) to the welded tube, and the welding powder free space of the tube being filled with a protective gas. The object of the invention is to provide a method for continuous production of a tubular welding electrode, especially a tubular welding electrode for welding without external supply of protective gas. The invention is characterized by the fact that the welding powder is introduced in a container (11), which is evacuated of an essential portion of its air content, whereupon the protective gas is introduced into the container until a positive pressure has been reached therein, and the powder-protective gas-mixture thereupon being supplied to the tube (21), whereby in the conduit (18, 19) is maintained a gas pressure, which is somewhat higher than the atmospheric pressure.

Date Jul. 3, 1986.A method of measuring the volume (V) of a gas in a container (20) comprises varying the container volume according to a sine wave between a minimum and a maximum value, the variation being made at a constant frequency but at varying amplitude, to obtain a predetermined pressure difference ( DELTA p), and the volume difference ( DELTA V) corresponding to said predetermined pressure difference ( DELTA p) being determined by detecting the points of time when at least two points on the sine wave are attained which correspond to two predetermined values of the container volume. By measuring the time between the two points on the sine wave, the sine wave peak values for the volume difference ( DELTA V) corresponding to said predetermined pressure difference ( DELTA p) may be calculated and, thus, the said volume difference ( DELTA V). By means of the formula V= DELTA Vxp0x eta / DELTA p, wherein p0=the static pressure and  eta =Cp/Cv wherein Cp an Cv are the specific heat capacity at, respectively, constant pressure and constant volume for the gas within the container, the gas volume (V) in the container may then be determined. An apparatus for carrying the method into effect has also been constructed.

Abstract: In a trunk circuit for digital signals, a digital subtracting circuit (3a) and an adaptive transversal filter (7) are inserted in a shunt branch between the transmitting path (6) and the receiving path (19). On the trunk circuit (6,19), digital signals are transmitted in the original frequency band from 0.3 to 3.4 kHz. A direct voltage or a digital sweep or noise signal in the original frequency bands 0 to 0.3 and 3.4 to 4 kHz, which are generated in the digital additional-signal generator (15a), are superimposed on such a received signal via a digital adding circuit (11a). This prevents the coefficients from escaping from a predetermined band. When analog/digital and digital/analog converters are inserted for digital operation of the adaptive transversal filter (7), connection to analog trunk circuits is also possible. These echo compensators are used, in particular, in international gateway exchanges. <IMAGE>
