Abstract: 1449893 Protecting inverters EATON CORP 15 Nov 1973 [15 Nov 1972] 53019/73 Heading H2F In an inverter for supplying power from a D.C. source to a load 18, sensing means 26 is provided responsive to excess current or shootthrough in the inverter 20 and arranged to turn on additional semi-conductor switching devices so as to share the fault current and a delayed opening contactor 30 arranged to interrupt the supply current after a predetermined time and further means operative during said predetermined time to attempt to clear the fault condition. As described, the inverter 20 obtains its D.C. supply by rectifying at 14 the threephase mains 32. In the event of a shoot-through or a short circuit across the motor load 18, the voltage drop due to the limiting resistor or inductor 22 is sensed at 26 so that logic circuit 49 turns on all the main thyristors of the inverter 20 so as to share the fault current. Commutating thyristors of the inverter 20 are also turned on and, if they succeed in clearing the fault within 20ms, the sensing device 26 restores normal operation; otherwise the time delay contactor 30 opens and has to be manually reset. Some of the commutating thyristors of inverter 20 may be turned on so as further to distribute the fault current. Fig. 2 (not shown) depicts one phase of the inverter 20 and comprises a series connected pair of main thyristors with inverse diodes and a series-connected pair of commutating thyristors coupled to the junction of the main thyristors via a series resonant circuit.

Title: Course difference logic
IPC: G01C17/26
Filed: 1973-11-19
Abstract: 1409640 Course difference logic LAITRAM CORP 19 Nov 1973 [22 Nov 1972] 53620/73 Heading H3H Logic circuitry for use with a digital compass provides signals indicating the difference between an actual and a required course, and the sense of the difference. The compass orientation is sensed by a rotary shaft encoder attached thereto (Fig. 1, not shown). The sensed light signals therefrom give rise to Gray code signals 94 representing numbers in the range 76-135 (0-359 degrees) which are converted at 200 into binary form; the most significant Gray code bit is inverted so that the output from 200 represents the complement of the actual reading. This value presets a counter 204 which is incremented by pulses from a clock 208 until a count of 435 is sensed by a decoder 206; the number of pulses produced thus represents the actual course in degrees. The required course is set on a device 216, Fig. 4 (not shown) attached to a rotary shaft encoder which generates a signal B to preset a counter 218. The pulses A from 208 are detected by a device 214 which enables a triggered clock 212, Fig. 5 (not shown): this feeds pulses to a gate 222 at the same rate as pulses A while these are being received, and at a slower rate thereafter. Gate 222 is enabled by the SENSE output of a decoder 220 until counter 218 reaches 435, the number of pulses B passing through 222 indicating the required course in degrees. Pulses A, B are fed to a gate 224 which produces a number of pulses equal to the difference between the actual and the required courses (i.e. number of pulses A unaccompanied by pulses B or vice versa); the SENSE signal indicates which course corresponds to the greater angle.

Abstract: 1,187,886. Fuel elements. ALKEM, ALPHACHEMIE UND-METALLURGIE G.m.b.H. 20 Nov., 1968 [21 Nov., 1967], No. 55038/68. Heading G6C. The plutonium content of nuclear fuel elements is non-destructively measured by measuring simultaneously or successively the alphadecay heat and the neutron radiation rate. Where extreme accuracy is required these results may be compared with a spectrometric analysis. The simultaneous measurement of the decay heat and the neutron radiation may be effected in a heavy water calorimeter with neutron counters mounted in a water-bath arranged around the calorimeter. The non- fissile components, i.e. plutonium 238 and plutonium 240 yield more than two neutrons at each spontaneous fission and these are detected by coincident neutron counting systems. A comparison of the spontaneous fission rate with the total neutron emission rate thus indicates the fissile plutonium content.
