In one embodiment the plate 11 is secured to a wall 1 by clamps, bolts or a holder and after detonation of the charge the pipe becomes welded into the bore but although the pipe is thrust against the aperture in the plate, the presence of oxides, &c. prevents welding thereto. The wider end of the aperture 12 in the plate has a radius of curvature 13 which may be at least equal to the width of the gap 3 between the pipe and the bore and at most equal to two and a half times the said width then upon detonation the portion of pipe 2 above the bore will be severed. If the radius of curvature is at least equal to four times the width of the gap shearing does not take place. A number of pipes may be welded simultaneously into a numbr of bores in a wall. A smaller pipe may be welded into the wall of a larger pipe, the upper plate being curved to fit the interior of the larger pipe and being supported by a block fixed in the larger pipe. One of the electrodes for the firing charge is in contact with a conductor in the block and the electric firing supply is connected to the pipe and to the conductor in the block.

Abstract: Method for readout from multiscale encoders wherein the fine readout digits information signals formed in Gray code by means of light flux modulation from the fine readout code mask graduations are transformed into electrical signs by photosensitive read elements. Interaction of the sensing element with the most significant digit code intervals of the full range fine readout masks forms an imitating electrical signal, the logical level transition of which occurs every time that the coarse readout digits information signals logical level must be changed. Through the interaction of the coarse readout mask digital tracks with pairs of sensing elements, for each digit there are formed pairs of auxiliary electrical signals, the interval between two adjacent edges of which is shorter than the period of the imitating electrical signal and includes all positions in which the coarse readout digit information signal must change its logical state, from the code intervals of which the given pair of auxiliary signals is formed. The invention includes a muetiturn absolute angle-code converter for use with the above method, the converter, having two code mask disks for coarse and fine readout which are kinematically joined by means of gear transmission, and readout elements which are located over the digital tracks of the fine readout mask.

Abstract: A slide valve with a slightly wedge-formed valve member arranged to close a flow duct by a cross-wise movement relative to the duct. There are annular sealing surfaces surrounding the flow duct and they are engageable by sealing side portions of the valve member for closing the valve. The sealing side portions of the valve member are considerably narrower than the annular sealing surfaces of the flow duct and are, in the closing position of the valve, located at a relatively great distance from the inner edge of the annular sealing surfaces. The sealing side portions of the valve member are of a softer material than the annular sealing surfaces, and hence, are subject to a repeated grinding against the annular sealing surfaces, when operating the valve. The sealing side portions of the valve member may be located each to a separate slide unit journalled in a body portion of the valve member. The slide units are in that case arranged to be slightly rotated by the opening movement of the valve.
