Abstract: 502,043. Oscillographs. BOTH, E. T. Sept. 13, 1937, No. 24871. [Class 37] A movable armature type of electrocardiograph wherein a fine trace is made by a scriber in a layer of material on glass, comprises readily removable cardiogram discs of transparent material coated on their under surfaces with an opaque substance, the discs being rotated on a turntable that has a smaller diameter than the discs. A moving-coil instrument is described and this is supplied through a valve amplifier, the scriber traces being formed on the portion of a sooted glass disc beyond the edge of the turntable and being viewed through a microscope which has a grating in the eyepiece for quantitive comparisons. The turntable 2, Fig. 3, is frictionally driven from a spring shaft 4 and is steadied by a spring arm 8, the replaceable cardiogram discs 1 being provided with centring knobs 16 and being located under a microscope 60. The moving-coil unit has a permanent magnet 21, the coil former 23 being supported on flexible arms 24 permitting axial movement of the coil. An arm 25, Fig. 5, flexible at 27, carries a diamond pointed scriber 26, and it is prevented from moving in the direction of rotation of the turntable 2 by a twisted arm 29. Damping of the scriber is effected by vertical and horizontal lugs 35, 36 on arm 34. An arm 32 can be rocked to withdraw the scriber from the cardiogram disc 1. Rocking of the arm 32 is effected by a depressible knob 44 which also controls the motor brake 46. Curves produced in respect of different heart-action potentials are traced on separate areas of the discs, the electromagnetic instrument system being movable to this purpose. Such movement is effected by a cam 55, Fig. 3, operated by knob 57 and engaging the magnet 21. At the same time, switch positions are made at 58 to connect the different leads to the moving- coil. The microscope 60 is mounted in a socket 62 and a lamp 68 energized by battery 70 and switch 71 illuminates the disc from below. The lamp 68 is in the filament circuit of the valve amplifier, Fig. 2, and can be energized independently of the resistancecoupled valves V<SP>1</SP>... V<SP>3</SP>. The screen grid voltages are controlled by resistor R, the anode circuits including condensers C<SP>1</SP>, C<SP>2</SP> of the order of two microfarads. The instrument, movement is damped by a resistor R<SP>1</SP> which may be a winding on an aluminium former. In order to cancel out any alternating-current introduced by a patient, the potentiometer P in the input has its metal slider knob 85 connected through a condenser C3. For calibration purposes, the grating, Fig. 6, has lines 67, 69 for time and amplitude ordinates, resistances R<SP>2</SP>, R<SP>3</SP> being switched into circuit by cam 88 and the preferable calibration giving a scriber deflection of 0À3 mm. for one millivolt with 0À03 inch per second on the abscissa.
