Abstract: The invention relates to a method for modifying a pipe, in which the host pipe (2) to be modified receives a replacement pipe (4) having smaller diameter together with a conduit or conduits (5) in order to form additional channels (8). In accordance with the invention, the flexible conduits (5) are disposed on top of the replacement pipe (4) and are pressurised so as to press the replacement pipe against the bottom of the host pipe (2) for mutual positioning of the conduits, the replacement pipe and the host pipe. After this, the free space remaining within the host pipe (2) is filled with liquid filler (7) while the pressurised conduits (5) prevent them and the replacement pipe from being dislodged, and finally the filler (7) is cured in order to lock the conduits and the replacement pipe into position. The invention is suitable e.g. for renewal of old drain pipes comprising insertion of a new drain pipe (4) to act as a replacement pipe within an old pipe (2) acting as the host pipe and providing additional channels (8) for service, rain or drying waters or cablings (9).

Individual healds are spring-loaded towards the left and are moved positively to the right by a bar 28 on each cycle. A detent 41 is normally held clear of the heald by a permanent magnet 38 acting through a pole piece 36 surrounded by a coil 37; if a heald is to be retained in its right-hand position, a momentary current is passed through the coil 37 to cancel the magnetic field, thereby allowing the detent to enter a notch 47 in the heald. Next time the bar 28 moves to the right, it pushes the heald slightly, causing the wall 45 of the notch to press the detent down on to the pole 36 again. One permanent magnet may serve a number of poles 36. Instead of using permanent magnets, the coils 37 may be normally energized, the current being momentarily interrupted when a detent is to be released.

Abstract: 1,054,031. Gas turbine jet engines. BRISTOL SIDDELEY ENGINES Ltd. April 16, 1964 [April 16, 1963], No.14883/63. Headings F1G, F1J and F1T. A gas turbine jet engine comprises a stator structure which has a front air intake end and carries a system of journal bearings for a rotor shaft, a rotor disc which carries a first row of axial-flow compressor blades and which is attached to the rotor shaft in front of the system of journal bearings by means which are releasable from the front of the engine so as to permit removal of the disc by a forward movement without disturbing any subsequent blade-carrying rotor disc and a row of stator blades which follows the first row of rotor blades and which is attached to the stator structure in a manner which permits removal of these rotor blades by a forward non-radial movement without disturbing any subsequent stator blades. The forward end of a by-pass type gas turbine jet engine is shown in Fig. 1, a first portion of the air delivered by the low pressure compressor passing into the high pressure compressor and the remainder passing into the by-pass passage 25, 26. The forward part of the engine comprises an outer casing 1 carrying radial arms 2 which support an inner casing wall 3 and an intermediate ring 4, the wall 1 being secured to the casing 26 and the ring 4 being secured to the casing 25 and to the high pressure compressor casing 22. A diaphragm member 5 is secured to the wall 3 and supports a bearing 6 in which the forward end of the shaft 7 of the low pressure assembly is mounted. The wall 3 has an inwardly directed flange at its rearward end which serves to support a bearing 15 in which the forward end of the high pressure rotary system is mounted. The shaft 7 has a flange 8 to which the low pressure compressor rotor discs 9, 10 are secured by bolts 11. The rotor discs 10, 9 carry blades 10a, 9a which co-operate with stator blades 34, 29, the stator blades 34 being secured to the casing 1 by means of a ring 37 which is secured to the casing by bolts 38, the ring 37 forming a fixed shroud ring for the rotor blades 10a. The ring 37 also serves to secure a ring member 28 within a recess 27 in the casing 1, the ring 28 serving as a support for stator blades 29 and also as a fixed shroud ring for the rotor blades 9a. The stator blades 29 are secured at their inner ends to a ring member 30 which is secured by bolts 31 to the wall 3. After removal of the fairing cone 12 the nuts on the tie-bolts 11 may be removed and thus the rotor disc 10. The stator ring 37 and the blade row 34 may then be removed, then the rotor disc 9 and the blade row 29. In a second embodiment, the forward casing portion is of fabricated sheet metal construction and a double row of second stage stator blades is welded to it. The first stage stator blades are secured to a casing portion which is connected to the forward casing portion by bolts so that these blades and casing portion may be removed axially once the first stage rotor disc has been removed.
