Abstract: 1,170,941. Repeater housings. POSTMASTER GENERAL. 25 May, 1967 [25 May, 1966], No. 23369/66. Heading H2E. An aperture in the outer steel casing 6, Fig. 1, of a submarine cable repeater housing is closed by a steel bulkhead 7, a castellated skirt member 10 on the casing 6 around the aperture and an adjacent castellated skirt portion 15 of the bulkhead 7 being coaxial and of the same diameter, and a polythene sealing member 16 is moulded around members 10, 15 being keyed to the castellations thereof, as described and claimed in Specification 1,170,942. An extension sleeve 17, Fig. 2, is screwed on to threaded projection 9 of casing 6, and a retaining ring 19 is screwed into the other end of sleeve 17, the ring 19 having a plurality of threaded holes equidistantly spaced around it, each hole containing a grub-screw 21 which exerts pressure on a push-rod 20 bearing against member 15, to retain bulkhead 7 against casing 6; a lead seal 22 may be located between the latter two members. Member 15 may be shaped to provide an annular groove which receives an inner flange 23 of the moulded sealing member 16; and the recess in the bulkhead 7 may be enlarged to receive a heater. In a further modification (Fig. 3, not shown), sealing member 16 is reduced in diameter around flange 23. A cable 3 (Fig. 1) is sealed into inner casing 2 of the repeater housing, and the cable 14 for a moisture detector 13 is sealed through bulkhead 7, both in known manner.
