Title: Improvements in or connected with gas meters
IPC: G01F3/22
Filed: 1946-04-30
Abstract: 670,557. Gas meters. NEWTON, R. April 30, 1946 [May 3, 1945], No. 13005/46. Class 54. In a dry gas meter of the diaphragm type a valve plate 48 carrying trough-shaped valve seatings 53 and complementary valve covers 59 separates a base section 1 containing a sealed inner casing 13 from a cover section 2 containing housings 7 for the gas connections and conventional valve and index mechanisms. The inner casing 13 is divided by a partition 14 into two chambers each containing a diaphragm unit 29 soldered to the top limb of an angled circumferential ring 19 and associated with a flag rod 34 which passes through a gland 36 in the valve plate 48 and through a sealing gland in which a top member 37, Fig. 7, secured to the casing 13 is connected to a member 40 on the flag rod by a resilient gland member 44 made of synthetic rubber or flexible thermoplastic material. Inlet and outlet tubes 81 and 82 respectively formed with hexagonal flanges 83 bearing against washers 10 recessed into the housings 7 are screwed into sockets 80 on the valve plate 48, thus securing the cover 2 to said valve plate with the interposition of a gasket 50. A locking bar 85 secured by sealed screws to the cover 2 co-acts with the flanges 83 to prevent interference with the meter. Conduits 74 and 75 supported below the tubes 81 and 82 on hollow columns 78 connect said tubes to the valve seating 53, which is formed with ports 55, 56 and 57 co-operating with gasways 60, 61 and 62 in the valve covers 59, ducts as at 77 providing connections with the compartments of the inner casing 13. With the valve covers 59 in the position shown in Fig. 12, gas is prevented from flowing through the port 56 by a wall 6a linking the sealing faces 63 of said cover. Plates 68 adjustably secured in slots formed in the valve covers 59 are connected to the valve mechanism, and lubricating oil stored in recesses 65 in said covers passes to the edges thereof in transverse grooves. Excessive loss of pressure in the meter is said to be prevented by the comparatively direct gas paths provided by the above valve construction and by the use of the flexible sealing glands on the flag rods. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 670,606. This subject-matter does not appear in the Specification as accepted.

Abstract: 295,669. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). May 17, 1927. Wired wireless systems.-In a system for transferring high-frequency carrier-current from a signalling source T for distribution over a power line or network LL<1>, the coupling wire C, C<1> is given a high impedance to ground, for the particiilar carrier-frequency employed so as to facilitate the flow of signalling energy directly to the line L-L<1> and rpevent leakage through the low-impedance path normally afforded by the inherent capacity of the line to ground. The impedance elements may consist of inductances branched across the coupling wire CC<1> and earth, or, as shown in Fig. 4, where two separate carrier-frequencies are fed to the distributing line, they may take the form of loop circuits or networks K, K<1> designed to give two different points of antiresonance with the line capacity. Where the wire CC<1> is itself grounded, as shown in Fig. 5, so that the coupling with the line LL<1> is inductive instead of capacitive, the loading coils L2, L<1>2 : ensure that the signalling current enters the ground at the end C<1> only. The same method may be employed for transferring carrier signals to a moving train or other vehicle where it is impossible to connect the carrier apparatus directly to the receiving line.
