Title: Time delay gating circuit
IPC: H04N5/16
Filed: 1965-10-20
Abstract: 1,107,997. Delayed gating circuits. TEKTRONIX Inc. 20 Oct., 1965 [30 Oct., 1964], No. 44473/65. Heading H3T. A delayed gating circuit includes a blocking oscillator which conducts and then becomes non-conducting again before the gate is opened. In Fig. 1 transistor 10 forms a monostable blocking oscillator which is normally biased off by a positive voltage applied to the base through resistors 22, 24 and transformer winding 18. A negative trigger pulse at 34 lifts the bias momentarily and allows the oscillator to perform one cycle, the transistor going into saturation by feed-back through diode 20. Gating diodes 36, 38 are normally reversed biased by the voltages on capacitors 48, 50 from the previous cycle and the voltage induced in secondary winding 40 when the transistor conducts merely increases this reverse bias. When the collector current ceases to rise, the transistor base becomes reverse biased again and the transistor is cut off. The fall in collector current then induces a secondary voltage in the opposite direction which turns on the diodes 36, 38 and allows a signal applied at 46 to reach the output. The circuit is particularly suitable for clamping the back porch level in a waveform monitor for a television transmitter, the complete video signal being applied to terminal 46, and the trigger input at 34 being obtained by differentiating the trailing edge of the sync. pulse. If the back porch level of one cycle differs from that of the previous cycle, a step waveform is produced at 44 representing the difference, and this is applied to the vertical amplifier of the monitor to maintain the back porch level constant. The delay in the gating circuit is controlled by resistor 16, and the duration of the " open " period is varied by resistors 52, 54. A four-diode bridge may be used as the gate, and resistor 24 may be omitted if variation with different transistor parameters is permissible. The R.C. networks 48, 52, 50, 54 may be replaced by separate D.C. sources. The transistor may be of the NPN type. The trigger pulses can be derived from the leading edge of the sync. pulse and can be applied to the emitter or collector of the transistor. The blocking oscillator may be astable, triggered at a rate equal to or higher than its free-running frequency.

Filed: 1970-09-25
Abstract: 1302685 Controlling reactors SIEMENS AG 25 Sept 1970 [27 Sept 1969] 45907/70 Heading G6C  In a pressurized-water nuclear reactor, output is adjusted by repositioning of a primary bank of control rods, while variations in xenon and Samarium poisoning, due to repositioning of the primary rods, are compensated by repositioning of a secondary bank of like control rods. The secondary bank may comprise subsidiary banks which are individually repositionable. Additional control rods, comprising only parts having neutron absorber, are used to improve output distribution over the core and are inserted to a depth dependent upon measured neutron flux. Changes in reactivity; due to fuel burn-up, are controlled by addition of boric acid to the coolant. Since the rods of the secondary bank are deeply inserted, while those of the primary bank are inserted only in upper regions of the core, their functions may be interchanged between banks when necessary to compensate for differing local burn-up.

Make-up air is admitted to the closed circuit through a conduit 9 via an inlet 7, throttle 9a, pump 8 and decarbonation unit 10. A proportion of the exhaust is removed through a conduit 11 having a condenser 12 for recovering water. The cell 1 supplies current to a load 2 which may vary. For efficient cell operation it is required that the fluid-flow rate through conduits 9, 11 varies in accordance with the load current. This control is achieved by a motor M which regulates the throttles 9a, 3a in response to a signal from a comparator 21, the comparator receiving an input voltage signal over lines 13, 14, the magnitude of this voltage signal being substantially proportional to the load current. The specification shows that such a control causes the oxygen concentration in the conduit 11 to remain constant and it also causes the ratio of the fluid-flow rates through conduits 9, 11 to remain constant. In a modification the conduit 11 is on the downstream side of the conduit 9. The electrical control system is described in greater detail with reference to Fig.2 (not shown).
