A metal ring 21 is fixed to the periphery of each handhole 10, an airtight fabric tube 23 being secured, outside the compartment, to the fixed ring 21 by an elastic ring 24. The other end of the tube 23 is attached by another elastic ring 27 to a metal ring 26 which is rotatable outside the fixed ring 21, ball bearings 28 being disposed between the rotatable ring 26 and the fixed ring 21. On rotation of the ring 26 which may be provided with a handle 34, the tube 23 is twisted and folded to close the opening 10. The ball bearings roll within a race formed by annular grooves 29, 30 in the rotatable and fixed rings 21, 26 and are held in spaced relationship by a flat strip bent to form a ring and having holes (not shown) to 'receive the balls 28. In another form of the invention which is applied to an artificial respirator (Fig. 9) the fabric tube 54 projects within the respiration chamber and one end of it is secured to a ring-shaped flange 46 of a plate 44 which is clamped between a plate 42 and a gasket 45 which bears against a wall 40 of the respiration chamber. The other end of the tube 54 is attached to a ring 49 which is rotated within the fixed ring 46 in order to twist and fold the tube 54 for closing the aperture 41. A continuous nylon bearing cord 53 is provided between the fixed and rotatable rings 46, 49. A rubber tube 58 for retaining the rotatable ring 49 in any desired position passes round an annular lip 50 on the exterior portion of the rotatable ring 49 and also round one of the screws 43 securing the plate 42. The length and tension of the rubber tubing 58 may be adjusted by an anchor block (not shown) through which the ends of the tubing pass. To prevent disconnection of the flexible tube 54 from the fixed ring 46 by pressure within the respiration chamber the tube 54 is provided with tabs (not shown) which are clamped between the plate 44 fixing the ring 46 and the gasket 45.

[Class 37.] In a system for signalling the position of substation switches to a main station, line faults are notified at the supervising station and their time duration is recorded. The three sub-stations 1, 2, 3 are connected, over the circuit 8, to the main station. In the event of a break in the line circuit relays 9 and 59 relapse and slow-operating relay 74 pulls up lighting lamp 82 and operating alarm 84. Relay 64 energizes and locks and timing magnet 78 operates to record the time of the fault. Slowacting relay 79 energizes in parallel with 78 and, by means of its self-interrupting contact 80, continually makes and breaks the circuit of 78 so that the duration of the fault is recorded. Faulty earths in the circuit are notified by relay 87 and indicator 88. The circuit paths from 86 are balanced by resistance 52 and, should a faulty earthing of the feed circuit occur, the balance is upset and 87 operates lighting lamp 93 and operating alarm 84. The indicator 88 is sensitfve to current direction and it moves to the right or left dependent on the position of the fault.
