Abstract: 1484157 Measuring strain electrically JO-LINE TOOLS Inc 15 Nov 1974 [14 Jan 1974] 49566/74 Heading G1N(A) [Also in Division H3]  In a strain read-out apparatus for a torque wrench a signal from a bridge comprising resistive strain gauges 17, 18 is integrated over a fixed interval of time as determined by counting means 96-98 which also provides a count to read-out means 30 corresponding to the time taken to reduce the integrated signal to a predetermined value when a signal of fixed value +e is subtracted therefrom. The bridge unbalance signal is fed to high gain amplifiers 71, 72 arranged so that only positive values are produced at their outputs. During the said fixed time interval transistor Q2 conducts and applies the output of resistor 79 to an integrator comprising amplifier 83 and capacitor 84. The bit level immediately adjacent to the most significant bit level in counter 98 provides for complementary switching of NAND gates 61, 62 to reverse the bridge excitation half-way through the fixed time interval thus ensuring that a positive signal is made available at the amplifier 83 irrespective of the direction of torque. On reaching the end of the fixed time interval the most significant bit level in counter 98 switches to high, the bridge excitation is removed by inverter 63, transistors Q2 and Q4 are rendered non-conductive and a fixed voltage +e is applied to the second input of amplifier 83 via transistor Q3 to begin a fixed decay rate. When the output of amplifier 83 goes to zero amplifier 88 provides a signal C which inhibits the clock oscillator 95 and enables de-coders 101, 102 and 103. At the end of a time delay determined by capacitor 91 and resistor 92 the clock oscillator 95 is enabled again and the fixed interval count repeated.

A duct burning system comprises a duct 6, a fuel injection manifold 11 disposed in the duct and a flame stabilizing gutter 12 disposed downstream of the manifold and aerodynamically in line therewith, the manifold having a first plurality of orifices 13 facing upstream and dimensioned for injecting the major portion of the fuel supplied to the manifold into the duct. A downstream-facing channel member 10 is disposed adjacent the manifold upstream thereof and into which the major portion of the fuel is injected. The manifold has a second plurality of orifices 14 facing substantially radially and dimensioned to inject the remaining portion of the fuel into the duct. The invention is described with reference to re-heat equipment of a gas turbine jet engine but is also applicable to combustion equipment in the by-pass duct of a gas turbine by-pass type jet engine. In the embodiment the orifices 14 are directed radially inwardly towards the centre of the duct. Fuel discharged from the orifices 13 is reversed in direction by the channel member 10 and flows as a "curtain" around the manifold 11. At high rates of fuel-flow, fuel injected radially inwardly through the orifices 14 can penetrate the fuel curtain and pass towards the centre of the duct thus avoiding the possibility of "rich extinction". At low rates of fuel-flow the fuel injected through orifices 14 does not penetrate the curtain and this avoids the possibility of "weak extinction".
