Title: Improvements in and relating to dry gas meters
IPC: G01F25/00
Filed: 1936-06-22
Abstract: 477,046. Counting-apparatus. BRAD. DOCK, T. C., and METERS, Ltd. June 22, 1936, No. 17336. [Class 106 (i)] In a dry gas-meter an indicator, additional to the usual counting mechanism, is provided to verify that the meter is working on a very light load, e.g., supplying gas to a gas-heated refrigerating apparatus. For this purpose a rotatable indicating element is mounted on the outside of the casing and the element follows by magnetic interaction the movements of a comparatively fastmoving member, such as the tangent arm, of the meter mechanism. The adjacent wall of the casing is made of non-magnetic material, such as brass, and the tangent arm may carry a permanent magnet of cobalt steel and act upon a compass needle placed on the casing. In an alternative arrangement the member on the tangent arm may be of magnetizable material and the indicator may comprise a freely rotatable magnetic needle.

Abstract: 1,166,131. Pipe joints. PARKINSON COWAN Ltd. 16 April, 1968 [15 April, 1967], No. 17393/67. Heading F2G. Air intake and flue pipes 1, 2 passing through holes 3, 4 in a wall, are positioned and sealed from the inside by means of a sleeve 6 of natural or silicone rubber which is bonded to the pipe at its outer end and to a slidable sleeve 7 at its other end, so that when the sleeve 7 is moved along the pipe a raised fold or head is formed in the rubber sleeve which can then be sealed against the wall by rearward movement of the pipe. Both pipes are secured in this position by a spring steel grip washer 8 having two holes and accommodated within the wall plaster 9 (Fig. 2, not shown). The sealing sleeve 6 may be of uniform section as shown, or it may be moulded to provide one or more rings of reduced section to enhance the radial expansion. Alternatively the sleeve may be expanded by the compression of a layer of plastic or adhesive material beneath the sleeve. Alternatively, the sleeve may be moulded with an expanded portion which is pulled down for insertion and then allowed to expand. In another form, the expansion is caused by twisting instead of axial movement.

Abstract: 971,856. Stopping pipes &c. LEE CO. May 3, 1963 [June 18, 1962], No. 17575/63. Heading F2P. Unthreaded openings in metal parts having relatively thin walls, e.g. pipes, tanks &c., are sealed by expansion of a plug assembly while exerting only radial force. A plug 12, of a generally cup shape, has a cylindrical outer surface 16 of a diameter to fit easily in the hole 49 to be sealed and, on the outside of the plug, annular grooves 17-22 with annular sealing lands 23-28 between the grooves. Within the plug 12 is a tapered inside surface 34 and, in the closed end, a screw-threaded blind hole 37. A hollow expander pin 14 has a tapered outer surface 40 for co-operating with the tapered surface 34 and a screw-threaded inner surface 42 with a diameter larger than that of the hole 37. To instal the plug assembly a bolt 50 with a nut 58 and a washer 60 are used, the nut being recessed at 59. As the nut 58 is screwed towards the plug the axial force in that direction is counteracted by an equal axial force in the opposite direction by the bolt 50 being threaded in the hole 37 and thus the only force applied to the wall of the hole 49 is radial. Specification 823,196 is referred to.
