Title: Method for folding an internal flexible lining for a cylindrical tank
Inventor: NITTEL WALTER F DR
IPC: B65D90/04
Filed: 1988-08-02
Abstract: The lining consists of at least two films which are joined tightly at their edges and are preferably of multi-layered construction, a filling nozzle being attached tightly in one film near to one of its ends. Firstly two film surfaces, lying opposite each other in respect of a centre line, are folded on the side facing away from the filling nozzle in each case about a bending line extending in the longitudinal direction symmetrically to the centre line in such a way that the longitudinal edges produced form an acute angle relative to the centre line. Then the films, which have been folded together, are rolled up from the end lying remote from the filling nozzle towards the filling nozzle in such a way that the latter projects outwards.

Abstract: A speed sensor for sensing the rotational speed of an N bladed fan such as in a turbo-machine application includes a polarization-preserving optical circuit (20) positioned adjacent the locus described by the remote ends of the blades (B). First (S₁,S₂,S₃,S₄) and second (S₅,S₆,S₇,S₈) sets of sensing segments of the optical circuit (20) are spaced apart from one another by an angular spacing equal to that of the blades and with the first set of sensing segments angularly offset from the second set. The optical circuit has two orthogonal polarization modes, and the first sets are cross-coupled by a coupler (C) to transpose the polarization modes. The orthogonal polarization modes of optical energy launched into the optical circuit at an input (22) are subjected to phase shifts as the optical fibre is perturbed by pressure variations caused by the moving fan blades with the cumulative phase shift in each portion of the optical circuit subtracted as a consequence of the cross-coupling and the resulting light output at an   output (24) having an intensity or other characteristics which varies as a function of the rotational speed of the fan.

Abstract: An apparatus for neutralizing mines includes several strands (12) of explosive charge which are adapted to be rolled up into a cable (10). The cable containing the strands of explosive charge can be launched across a mine field by a rocket (20). The cable (10) is opened and the strands of explosive (12) are deployed to form a two dimensional array disposed a certain distance (4) above the ground. The strands of charge are separated by a fixed distance which is less than or equal to the distance of the strands of charge above the ground. Upon detonation of the explosive a substantially uniform blast wave is created exerting uniform pressure and impulse on the mine field below. The detonation should occur substantially simultaneously so that the blast from adjacent charges will interact thereby creating a planar wavefront.

Abstract: This invention relates to an improvement in investment casting process wherein molds or cores are prepared by forming them around a polymer pattern and then dissolving the pattern with a solvent. Investment casting is widely used for casting complex metal parts such as, for example, engine and motor components. The improved process comprises: (a) forming the mold or core around the pattern; (b) heating the mold or core; (c) dunking or spraying the mold or core with the solvent until the pattern is dissolved; (d) placing the mold or core in a drying chamber in the path of cir­culating heated air; (e) cooling the air to condense the solvent; (f) recovering the condensed solvent; and (g) reheating the air until it is no longer saturated with solvent and recycling the air to the drying cham­ber. The preliminary heating step can reduce solvent losses by 66 percent and the entire improved process can reduce solvent losses by about 90 percent.

Abstract: For the accurate positioning of equipment parts (1) at given connection points (3) on the supporting structure for magnetic suspension lines, the fixing of the equipment parts (1) demands great precision, referred to the location of the line, and a rigid, force- absorbing connection with respect to the supporting structure is required. Adjustable screw connections have proved to be very complicated in assembly terms and have therefore been replaced by a computer-controlled machining of connection elements (2) for the equipment parts (1), which are fixedly connected to the track support. This machining and also the assembly of the equipment parts (1) can be simplified by determining the desired positions of the connection elements (2) relative to the connection points (3), providing the connection elements (2) with spacers (4) which ensure their desired position relative to the connection points (3) and by screwing said elements at the particular connection points (3) to the track support.
