Title: Defibrillators
IPC: A61N1/39
Filed: 1972-09-29
Abstract: 1435709 Defibrillators J F PANTRIDGE and J ANDERSON 1 Oct 1973 [29 Sept 1972] 45117/72 Heading A5R A defibrillator, for applying an electric shock to a patient, comprises a capacitor 35 which is charged by a direct current source and then discharged in series with an inductor 38 through electrodes 39, 40 in contact with the patient. The charging source consists of a pushpull oscillator 11, powered by a niokelcadmium rechargeable battery 10, followed by a rectifier and voltage multiplier 18. The values of capacitance, inductance and charging energy level are selected so that, for a patient representing a load resistance of 50-75 ohms, the voltage wave form across the electrodes has a duration of 10-16 milliseconds, a peak value not more than 4 kilovolts and a minimum rise time of 1000 microseconds. Typical values are 50 microfarads for the capacitor 35 and 50 millihenries, 18 ohms resistance for the inductor 38. Push button switches 41, 42 connected in series are provided on the electrodes 39, 40 respectively. The equipment is controlled by means of the three-position switch 45 in which the movable blade 44 is spring-loaded to rest normally in connection with contact 46. In this position, when both switches 41, 42 are closed, relay 33 is energised and contact 34 moves to touch the fixed contact 37, thus discharging capacitor 35 through inductor 38 into -the electrodes 39, 40. When the blade 44 of switch 45 is turned manually to touch contact 47 the oscillator 11 is excited and generates an a.c. voltage of frequency about 20 kHz. An output voltage of one kilovolt peak is induced into the secondary 14 of transformer 15. The voltage rectifying and multiplying circuit 18 then generates a d.c. output of 4 kilovolts between the live line 30 and the earth line 31. The normal configuration of relay 33 is with contact 34 touching fixed contact 32 so that capacitor 35 becomes charged to a maximum of 4 kV, a process taking about 7 sec. The third position of switch 45, with blade 44 touching contact 48 produces discharge of the capacitor 35 via relay 50. Both relays 33 and 50 are of sealed gas-filled type for high voltage use. A protective resistor 80 is provided so that when capacitor 35 is discharged, the capacitors 23-28 are also discharged, through resistor 80. This arrangement obviates the surge which would be produced if capacitor 35 in a discharged state were to be connected to capacitors 23-28 when charged. A meter 60 is provided to indicate the energy in watt-sec stored in capacitor 35 thus enabling the operator by the use of switch 45 to control the energy of the shock inflicted. A second meter 63 indicates the state of charge of the battery. Oscillascope traces, Figure 2 (not shown), of discharges into a 50 ohm load show that longer pulses and rise times are obtained than with certain prior art apparatus, Figures 3 and 4 (not shown).

IPC: G05B11/42
Filed: 1969-09-18
Abstract: 1,271,818. Automatic control systems. ROLLS-ROYCE Ltd. Sept. 18, 1969, No.46015/69. Heading G3R. An automatic control system incorporating a high gain control amplifier particularly for limiting jet pipe temperature in a gas turbine has a phase advancing circuit to supply a signal which is amplified and added to an error input to the amplifier when the phase advanced signal exceeds a determined value. A signal from a temperature transducer 28 responsive to jet pipe temperature is passed together with a reference voltage 35 through a comparator 32 to a high gain amplifier 46 controlling progressively a fuel valve solenoid 26 which is incorporated in a feedback loop. The comparator output 37 is also passed through a phase advancing circuit 44 (components R5, R6, C2) Fig.2 (not shown) together with another reference voltage 64 to a differential amplifier 60 which when the output exceeds a determined value closes relay contacts to charge through a resistor R2, a capacitor C1 the voltage across which is added to the error signal at point 48. When the error signal increases slowly the fuel valve solenoid is gradually energised which closes valve 22 gradually, but above a determined rate of rise of the error signal, the relay contacts are closed and hence capacitor C1 is charged and its voltage added to the error signal so that valve 2 is closed more rapidly. When the rate of rise of the error signal falls, the circuit returns to its original state and capacitor C1 discharges through resistor R3 at the same or different rate. The circuit thus has increased gain for rapidly rising error signals. The system may be made responsive to several parameters by connecting them in series with the comparator input 30, alternatively by connecting them to a diode OR circuit so that only the highest input is effective. A detailed circuit is illustrated in Fig. 2 (not shown) in which the amplifier inputs are limited by reverse parallel diodes (D1-D4).
