Title: Instrument for Determining the Flame Reversion Pressure of Fuel Gases
Inventor: WAPLING GEORGE ARCHIBALD
IPC: G01N31/12
Filed: 1967-07-27
Abstract: 1,165,778. Testing fuel gases. NORTH THAMES GAS BOARD. May 23, 1968 [July 27, 1967], No. 34543/67. Heading G1B. An instrument for giving an indication of the flame reversion pressure of a fuel gas, and thus its quality, comprises a gas burner 7 provided with a flame sensing device 9 having two electrodes 12 for detecting whether the flame is lifted from or is burning at the burner 7, and an open bottom gas container 2 in a water container 1 a solenoid operated valve 4 connecting the container 2 either with a gas supply 6 or the burner 7 the arrangement being such that in use gas is first supplied to the container 2 thus displacing water and causing the water level to rise until the pressure in the container 2 reaches a predetermined value, as detected by the level reaching on electrode 16, thus short-circuiting electrodes 15, 16 connected to a controller 8 to operate the valve 4 allowing the gas to pass to the burner 7 where it is ignited by a pilot flame 24 and burns initially as a flame lifted from the burner until at the reversion pressure the flame reverts to the burner, the level of water in the container 1 at this instant, as reached by a float 17 coupled to a marker 18 for a chart 19, indicating the reversion pressure for the gas. The action of the instrument is controlled automatically by the controller 8 under response of signals received from the electrodes 15, 16 and the flame sensing electrodes 12. The flame sensing device also controls a locking mechanism 20 for the float 17 which only releases the float when the flame reverts to the burner 7, for sufficient time for the float to reach equilibrium at the water level and hence for the marker to produce a steady record of this level. If the gas is of standard quality the flame reversion pressure should be between 2 and 5 inches water gauge. An electrode 26 co-operating with an electrode 25 is positioned at the water level corresponding to a reversion pressure of 2 inches water gauge to give a warning signal when the water level falls below that of the electrode 26. A further electrode 27, also in circuit with the electrode 25, is positioned at a level corresponding to a reversion pressure of 1À8 inches water gauge, and this may be connected so as to cut-off the gas supply to the main if the reversion pressure falls to this value.

Abstract: 926,167. Delay line data-storage apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 17, 1960 [Oct. 16, 1959], No. 35135/59. Class 106 (1). Apparatus for re-timing data pulses in a multiplex system of the shared channel-type comprises a circulating delay-line store the cycle time of which is a sub-multiple of the total data-cycle time, so that by suitably gating input and output to the store, data on selected subchannels may be made available at different periods. The apparatus is described in connection with a 100-channel system in which each channel is time-shared between nine subchannels, the bit period being 1Á sec. Nine clock-pulse trains PP 1 -PP 9  each of 1Á sec. pulses at 9Á sec. intervals effecting the sharing are available as inputs to gates GI1, GO1 &c. controlling the input to delay-line store DL with capacity 100 bits. If, for example, data on line I1 on the sub-channels corresponding to PP 1  is to be retimed to PP 4  then PP 1  pulses are applied to GI1, together with an enabling signal TW1 of at least 900Á sec., to fill DL, a subsequent enabling signal TW2 and PP 4  pulses being applied to GO1 to gate out the data. The store DL may be shared between a number of lines I1-IN (each of which must have the 100 X 9 sub-channel arrangement) by enabling in turn (for at least 900Á sec.) gates GI1, GO 1, G12, GO2 &c. Erasure of data in DL is effected by inhibit gate G1 receiving output data. In a modification (not shown) the output of DL may be made available at two different times by use of two output gates in parallel; erasure in this case is effected not by read-out data but by separate signals applied to G1.
