Abstract: 1458307 Automatic current control  MAGNETIC ANALYSIS CORP 30 Jan 1974 [1 Feb 1973] 04312/74 Heading G3R [Also in Division G1] The average current supplied to a test coil of a pulse eddy current testing device is regulated by controlling the amplitude of pulses fed to a coil driver connected between a current source and the test coil. As shown, the primary coil 21 of an eddy current flaw detector is supplied with current from a D.C. source V by way of a line 43 and driver transistor Q1. An input square wave a is fed to a clipper circuit D1, 55 which determines the amplitude of pulses passed to transistor Q 1 by way of a drive circuit Q5, Q6, and thus controls the current flowing in the coil 21. The clipping level is set by a control signal b derived from the voltage drop across a current sensing resistor 41 which, due to the presence of a large capacitor 45, is responsive to the average current flowing in the coil 21. A Zener diode 23 and capacitor 24 serve to optimize the shape of the current pulses. The regulating circuit shown in Fig. 2, may form part of a flaw detection system, Fig. 1 (not shown), which is described and claimed in Specification 1405686 (Division G1).

Title: Improvements in devices for facilitating the starting of internal combustion engines
IPC: F01L13/08
Filed: 1928-02-17
Abstract: 295,193. Petersen, O. Feb. 17, 1928. Cam-actuated pumps; regulating delivery by bye-passes and by opening suction valves. - In order to facilitate starting in engines in which liquid fuel is injected in a single phase and is ignited by the heat of compression, the normal velocity of the fuel pump plunger relative to the engine speed is maintained, but the time for the commencement of injection is advanced without releasing the normal tension of the fuel valve spring, so that ignition may take place at the same time of the working stroke as during normal running. In one form, Fig. 3, the pump 30 is normally connected to the fuel-injection valve past a needle valve 37; this is closed at starting, when the fuel flows past a non-return valve 40 which prevents a drop of pressure in the entire delivery pipe between injections. In a further form, the fuel pump is actuated by a cam acting upon a lever pivoted upon an eccentric adjustable to shift the cam bowl to give an earlier injection. The eccentric may also be used to lift the lever from the cam when reversing. In the form shown in Fig. 5, in which the pump is provided with suction and delivery valves 44<1>, 43<1> and an overflow valve 58, a bye-pass 42 connecting the pump barrel with the suction chamber 44 is controlled by a needle valve 45 normally open. At starting, the valve 45 is closed by means of the lever 48 of the starting-air valve 49, acting through a link 47 and lever 46 upon a loading spring 50. In a further form, an overflow valve such as 58, Fig. 5, serves also as a suction valve and is actuated through a lever by one or other of two axially displaceable cams. The lever acts through a spring upon a collar on the valve spindle, a lighter spring beneath the collar holding the valve open during the suction stroke. The cam used at starting gives an earlier injection of fuel.
