Title: Improvements in or relating to fusible safety devices for pressure vessels or pipe systems
IPC: F16K17/38
Filed: 1938-09-27
Abstract: 504,257. Fusible pressure - relieving devices ; alloys. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Sept. 27, 1938, No. 28102. Convention date, Sept. 29, 1937. [Class 135] [Also in Gronps II and XIII] A pressure-relieving device for fluids comprises a fusible material disposed in a narrow channel which is bent or curved at at least one point and extends from the interior of the pressure vessel to the atmosphere so that the pressure medium is vented therethrough when the fusible material melts. Figs. 1 and 5 show two embodiments of the invention, and Fig. 6 shows a simple method of forcing the fusible metal into position. In this latter case, the bush 5 may be made of an alloy of 32 per cent lead, 50 per cent tin and 18 per cent cadmium in order to be readily fusible and to stand the strain of being forced into the threads when the plug is screwed home.

Abstract: 1327835 Diversity reception; interference reception COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 16 June 1971 [16 June 1970] 28177/71 Headings H4J and H4L The arrangement for combining two narrow band signals of the same frequency and derived from the same source to produce a common signal with an improved signal-to-noise ratio, disclosed in Specification 1,327,834 is extended to provide for the combination of three such signals. As shown in Fig. 3, the input signals are supplied to circuits K11, K12, K13 respectively, which provide signals S1, S2, S3 which are identical in magnitude and phase but differ only in respect of their noise content. These signals are added at 10 to produce their sum U and subtractors D11, D12 produce difference signals V 1  = S 1 -S 2  and V 2  = S 2 -S 3  respectively. Signals V 1 , V 2  are supplied to amplitude regulators Q11, Q12 respectively in a circuit X which operate as in the prior specification to produce outputs #V 1 , #V 2  of substantially constant effective value. These outputs are added at 11 and subtracted at 13 and the resulting signals are supplied to further amplitude regulators Q13, Q14 respectively. The output of Q14 is passed through a phase quadrature circuit 10 and added at 12 to the output of Q13 and subtracted at 14 from the output of Q13, the resulting outputs T 1 , T 2  being supplied to amplitude regulators Q15, Q16. The output #T 1  of Q15 and the signal U are supplied to an arrangement G 1 , Fig. 3, which as in the prior arrangement comprises two correlator-multipliers, the first of which receives the outputs U and #T 1  and the second of which receives #T 1  phase shifted by 90 degrees and the signal U. The output #T 2  of Q16 and the signal U are supplied to a similar arrangement G 2  and the four outputs from G 1 , G 2  are added to provide a signal P which is stated to be a pure noise signal identical to the noise content of signal U. This signal P is subtracted from signal U at D to provide a substantially noise-free output signal. A mathematical analysis is included.

Abstract: 684,669. Combustion apparatus. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Oct. 21, 1947, No. 28186/47. Class 75(i) [Also in Group XII] In a combustion apparatus in which combustion has to be supported by a ducted flow of combustion supporting gas of flame extinguishing velocity, the flow is divided in the ducting, a metered portion of the gas flowing via a diffusion passage to a stabilized pilot flame zone formed by an apertured baffle producing on its downstream side a localized reverse flow circulation, the fuel for the pilot zone being introduced upstream of the baffle so that it is carried by the metered gas and mixed therewith in the diffusion passage. The remainder of the gas by-passes the diffusion passage and pilot flame zone and mixes with the combustion gases from the latter zone on its downstream side. The fuel may be pulverulent or liquid. In Fig. 1 an outer duct 1 receives a high-speed air flow in direction A the inner duct 2 passing a metered part of the air its speed being increased by the neck 3. Jet 4 sprays fuel counter-current to the air, the two mixing in the diffusion passage 5, passing through the baffle 6 and being ignited by the plug 7 in the dead air pocket 8, burning in the portion 9. The air from the annular duct mixes with the combustion gases from the portion 9. The fuel is sprayed in by the ring jets 10 and 11 each jet giving a non- uniform distribution the patterns of which are complementary so as to give an overall uniform distribution. In another form of apparatus the combustion gases from the flame zone pass through a convergent duct having ports to enable the unmetered air to mix with the combustion gases.
