Title: Improvements in or relating to electric protective systems
IPC: H01T1/08
Filed: 1951-01-11
Abstract: 675,945. Protective arrangements. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 11, 1951 [Feb. 25, 1950], No. 824/51. Addition to 674,692. Class 38 (iv). In a protective system for series stabilizing condensers 3 in a transmission line 2, as described in the parent Specification, the blown spark gap 4 shunting the condensers is supplemented by a normally open electro-pneumatically-operated switch 9 which short-circuits the condensers if the gap 4 fails to break down, or if line fault conditions (which may or may not cause break-down of the gap) persist for a predetermined time. In the arrangement shown, the gap 4 is shunted by a further gap 8 having a higher break-down voltage, gap 8 breaking down if gap 4 fails to and energizing a current transformer 53 which, through a pilot valve 47, operates a main air valve 40 to cut-off air supply to a piston 12 for actuating switch 9. Spring 10 consequently closes the switch and the pressure built up in the exhaust system 67 by the downward movement of the piston operates a latch 69 for locking valve 40 the closed position, from which position it can be released, to re-open switch 9 after the fault has been cleared, by the manual opening of a normally closed valve 70 in the exhaust system. A manometer 71 connected to that system indicates the position of switch 9. Valve 40 may also be closed by a further pilot valve 48 controlled by either a potential transformer 55 and delayed relay 57, or current transformer 37 and delayed relay 63, so that the switchcontrolling valve 40 is closed either by sustained over-voltage across the condensers of insufficient value to break down gap 4, or by continuous break-down of the gap. In order to indicate break-down of any of the condensers these are arranged in two parallel connected groups and the different current distribution over the groups consequent upon break-down actuates a relay 77, which through a valve 80 and pressure switch 84 operates an indicator 86.

Title: Noise rejection circuits for particle counters
IPC: G01N15/00
Filed: 1970-01-08
Abstract: 1,254,671. Transistor pulse circuits. ROYCO INSTRUMENTS Inc. 8 Jan., 1970 [14 Jan., 1969], No. 937/70. Heading H3T. [Also in Division G4] Signals to be counted are distinguished from noise by comparing the amplitude of each signal with the average, signals exceeding the average opening a gate to register a count. Particles in a sample flow affect a photo detector 18. The composite signal of count pulses and noise is amplified at 19 and fed simultaneously to noise comparator 23 and a noise reject gate 22 which opens to a signal from 23 to operate the counter 21 before closing again. Noise comparator, Fig. 3.-The composite signal is amplified by Q1-Q4, and where necessary clipped by CR5, CR6, before being averaged by CR2 and C5 and further amplified by Q8, Q7. Potentiometer R19 is adjusted so that the potential applied to the base of Q6 is slightly higher than the average noise level. When, therefore, an amplified count signal is applied by Q4 to the base of Q5, the bi-stable Q5, Q6 is disturbed to produce a pulse Y which is applied to the noise reject gate 22, Fig. 5. This pulse is amplified at Q101, Q102 and differentiated before application to a one-shot multivibrator Q104, Q105, the resulting output from which cuts off FET Q107. Q107 normally shunts the composite signal at 6 to ground, but when Q107 is cut off this signal is applied at 7 to the counter. The counter returns a signal 56 to restore Q104, Q105. Alternatively, this multivibrator is restored by the trailing edge pulse 54 resulting from pulse Y, or by the characteristics of the circuit after a predetermined time.

Filed: 1979-01-09
Abstract: PURPOSE: To prevent a burn of each coil when locked by connecting a positive characteristic thermistor to the starting coil in series and a temperature sensitive protector to the main coil in series or to a common circuit of the both coils.  
     CONSTITUTION: The positive characteristic thermistor 7 the resistance of which increases as temperature rises is connected to the starting coil 2 of the induction motor in series, the temperature sensitive protector 6, for example, an embedded  type protector of temperature sensing bimetal system is connected to the main coil 1  in series. In this way, although a large current flows in the staring coil 2 when starting the motor, the current in the starting coil 2 decreases after several seconds because the resistance of the positive characteristic thermistor 7 increases suddenly. Also, when locked, since the temperature sensitive protector 6 operates as temperature of the main coil rises, a burn of the main coil can be prevented.
