Abstract: 1390732 Electrotherapy device NEURO SYSTEMS Inc 11 Jan 1973 1534/73 Heading A5R [Also in Division H1] An electrotherapy device, particularly for inducing sleep, comprises a first circuit producing a train of electric pulses, and a second circuit responsive to said first circuit to produce on electrodes 8, 9 a train of periodic bursts of alternating current with intervening dwell periods, each of said bursts comprising a plurality of positive and negative pulses of similar amplitude and having a zero vectorial current run whereby to avoid impressing net direct current on a patient. A relaxation oscillator comprising an R-C timing circuit 21, 22, 23 (or 24 or 25) and a unijunction transistor 20 activates a monostable multivibrator, comprising dual gate 29 and R-C timer 31, 32, 33, to repetitively open transistor gate 34 for the monostable period whereby an oscillator is energised repetitively for periods corresponding to the monostable period. The oscillator comprises a dual gate 36 with the output of each gate fed to the input of the other gate via R-C tine constant circuits, the output of the oscillator passing to a push-pull amplifier 46, 47 feeding electrodes 89 via a manually adjustable attenuator 51 and a timer attenuator 11, the instantaneous power output being limited by resistors 35, 44, 45. A neon 52 and a loudspeaker 54 provide visual and auditory stimulation. The device 11 acts to provide a gradual increase in signal current amplitude over a fixed period, e.g. 5 minutes, to a maximum level at which it remains for a preselected period, e.g. up to 50 minutes, whereafter a gradual decrease to zero occurs over a further fixed period, e.g. 5 minutes. The timer 11, Figure 6 (not shown) comprises a clockwork mechanism (60) driving a shaft (61) carrying wiper arms (67) and (71) of variable resistors (62) (63). On starting, wiper (71) runs over a high resistance part of the track of resistor (63) whilst wiper (67) runs over a low resistance part of the track of resistor (62). After the current increase period both wipers run over low resistance track portions for the pre-selected period, after which wiper (71) continues over its lowresistance track whilst wiper (67) runs over a high resistance track to reduce the current amplitude to zero. The period at maximum current amplitude is selected by rotating a winder knob (69) of mechanism (60) to a selected point on a time scale, such movement rotating the track of resistor (63) relative to its wiper and relative to the resistor (62), resistor (63) being retained in this position by a spring (74) as the mechanism (60) runs down. Movement of knob (69) from the zero position closes a switch 12 (68) in the power supply line to the alternating current burst generator.

Abstract: 492,887. Converting. SIEMENSSCHUCKERTWERKE AKT.-GES. Jan. 25, 1937, Nos. 2189 and 2190. Convention dates, Jan. 24, 1936 and March 13, 1936. Addition to 492,369. [Class 38 (ii)] Commutator switching arrangements.-A moving contact electric current converter as described in the parent Specification is provided with means for regulating the current and voltage by which the ratio of the period for which the contacts are closed to the period for which the contacts are open can be varied. When the converter is provided with sliding contacts, the instant of closure of these contacts can be varied by varying the length of the sliding contact or the fixed contacts or both. If the converter is provided with camoperated lifting contacts, each contact may be operated by two cam discs which can be relatively angularly adjusted or which are mounted on separate shafts driven by separate synchronous motors so that the period of contact closure is variable. Alternatively, the contacts may be closed by a cam by which the instants of closing of the contacts can be varied, the contacts being prevented from opening by an electromagnetic holding device until the current has fallen to a value permitting sparkless opening of the contacts. The Figure shows a converter in the instants at which the contacts 84, 85, shunted by impedances 80, are closed and opened, can be varied, the contacts being operated by wedge-shaped cams 87 carried on a shaft 86 driven by a synchronous motor 90 supplied through a phase shifting device 91. The shaft 86 is arranged to be movable in an axial direction by an electromagnetic device 97 acting against a spring 98, the device 97 being energized in accordance with circuit conditions such as the power transmitted or the voltage. The arrangements described above may be provided with means for variably premagnetizing the saturable impedances in series with the contacts. These means may comprise biassing windings energized through a regulating resistance. Alternatively, the cross-sections of the magnetic cores of the saturable impedances may be variable. In rectifier arrangements, the variation of the instants of opening of the contacts may be made dependent on the value of the back electromotive force in the load circuit or on the difference between this voltage and the D.C. voltage supplied by the rectifier or on the degree of smoothing of the direct current or on the amount and phase position of the harmonics present.
