	Oscillograph - LoveToKnow 1911
		In the Duddell oscillograph it is usual to place a pair of loops in the magnetic field, each with its own mirror, so that a pair of curves can be delineated at the same time, and if there is any difference in phase between them, it will be detected.
		In one form of Blondel's oscillograph, the vibrating system is a small magnetic needle carrying a mirror, but the principle on which it operates is the same as that of the instrument above described.
		The oscillograph can be made to exhibit optically the form of the current curve in non-cyclical phenomena, such as the discharge of a condenser.

	Oscillograph - MSN Encarta
		Oscillograph, instrument that records, on paper or film, wave patterns that are equivalent to the oscillations of an electric voltage, or that converts mechanical oscillations into an equivalent electric current before recording them on paper or film in the form of wave patterns.
		The electromechanical type of oscillograph consists in principle of a galvanometer (see Electric Meters) to which is attached an apparatus that records the movements of the galvanometer coil.
		The recording apparatus may consist of a mirror that reflects a beam of light from the moving coil upon a photographic film moving at a fixed rate, or it may be a lightweight pen or stylus connected to the coil that writes on a moving paper chart.

		Oscillographic curves may also be photographed with the use of dropping mercury electrodes in such a way that the exposure is made as the drop "breaks away" and a new drop begins to form.
		In oscillographic titration the depolarizer is titrated with a solution which reduces its concentration, by complex formation or precipitation for example.
		The practical application of oscillographic polarography was shown to be feasible by Kalvoda (11-13), who studied the behaviour of papaverine, pilocarpine, codeine, morphine, ethylmorphine, physostygmine, ephedrine, santonin, quinine and quinidine.

	Duddell
		Oscillograph is the instrument for indicating and recording time-varying electrical quantities, such as current and voltage.
		The operation of an electromagnetic oscillograph, like the operation of a d'Arsonval galvanometer, depends on the interaction of the field of a permanent magnet and a coil of wire through which an electric current is flowing.
		In the Duddell's oscillograph it is usual to place a pair of loops in the magnetic field, each with its own mirror, so that a pair of curves can be delineated at the same time, -and if there is any difference in phase between them, it will be detected.

	Yokogawa and the Electromagnetic Oscillograph - Yokogawa
		As imported oscillographs were still quite expensive in the early 1920s, Japanese laboratories soon developed their own electromagnetic oscillographs and Yokogawa commenced production of this device in 1924.
		This combustion test chart was produced with an electromagnetic oscillograph that recorded waveforms using electrical signals received from temperature detecting plugs, a piezo-pressure transducer, and other devices connected to the diesel engine.
		The heart of the measuring system in the electromagnetic oscillograph was the galvanometer mirror, a small (1 x 2 mm) vibrating element that had a thin ligament strip.

	THE BIOELECTRICAL INVESTIGATION OF SEXUALITY AND ANXIETY: A Skeptical Scrutiny of the Works and Theories of Wilhelm ...
		Reich measured the skin-potential in five different kinds of experiments: the resting potential of erogenous zones versus nonerogenous zones, tickling and rubbing versus firm pressure, the tongue of an "orally erotic" subject being administered sugar versus salt, masturbation, and heterosexual couples kissing and otherwise engaging in foreplay.
		The person reading the oscillograph when the subject calls out "rising" or "falling" can trick himself into believing the trend really is rising or falling at that moment when in fact it's doing nothing of the sort.
		The text describing the experiment that created this graph says that the subject claimed, after the fact, to have experienced strong sensations of pleasure "immediately at the start and approximately at the end" of the tickling, but it does not say that the subject announced her sensations while they were happening.

		The #801 Pen Mount is the "cradle" that mounts at the top of the oscillograph shaft and adapts the pen to the shaft.
		An Allen screw secures the adaptor to the shaft and pen spacing is achieved by loosening the screw, positioning the pen and tightening the screw.
		On older Grass recorders, the adaptor was insulated from the oscillograph shaft with a fiberglass bushing.

	KANAREV: PROCEDURE ANALYSIS OF MEASUREMENT OF ELECTRIC POWER CONSUMED BY THE WATER ELECTRIC GENERATOR OF HEAT
		Structural diagram of measurement of electric values of the water electric generator of heat: 1 –cell of the water electric generator of heat; 2 – electric oscillograph; 3 – pulse generator; 4 – voltage pulse; 5 – current pulse; the rest units of the diagram correspond to conventional designations.
		That’s why the oscillograph readings, which differ from the readings of the voltmeter and the ammeter duplicating it by 5%, are considered to be unquestionable.
		On this basis, a conclusion is drawn that an index of power efficiency of the processes, which take place in the cell of the water electric generator of heat, is nearly 4000%.

	Low Current Electrolysis of Water by Prof. Kanarev
		A series of additional experiments accompanying this question is shown that a low current electrolyzer cell is a capacitor being discharged gradually under the influence of electrolytical processes, which take place in it.
		A value of this discharge is compensated by the pulses of voltage, which mean value is considerably less than a constant value of charge voltage of this capacitor.
		It appears from this that in order to calculate energy consumed by the low current electrolyzer cell from the line it is necessary to use voltage, which is registered not by the voltmeter, but by the oscillograph.

	Dead Media:Working Note 47.3:Comments
		This device is an "oscillograph", built by Westinghouse in, I believe, 1927.
		The oscillograph is an oscilloscope-like device that does not use a cathode-ray tube or electronic components, but operates optically-mechanically and electrically (for illumination, motor, and vibration).
		It shines a projection bulb, which picks up a "cross-hairs" targeting image, through 7 small prisms to adjustable mirrors mounted on top of 7 vibrating galvanometers, each of which is connected by the user to input signals of the respective frequencies to be studied, via pairs of binding posts on the sides of the machines.

	Fooled by Magnetics
		The larger value from the meters is probably due to their measurement at a lower value of current excitation than 0.1 A, with even less saturating effect than shown in the oscillograph above.
		This particular transformer (which is typical of common-mode line-filter transformers of the 25 mm EE core size) shows a knee in its current curve at about 300 mA.
		Although the first oscillograph correctly displays magnetics behavior at a large (1 A/div) scale factor, it shows the transformer core deeply in saturation.

	1934 - Rutherford discovers fusion
		The shape of these curves is due to the fact that protons gave too small a deflection in the oscillograph to be easily counted except over the last five centimetres of their path.
		On these data it is natural to assume that the particles are emitted in pairs opposite one another, and that the difference in range arises from a difference in mass, and hence of the velocity and energy.
		For example, it is difficult to disentangle the emission of neutrons characteristic of lithium and beryllium from the spurious effect due to contamination by diplogen.

	Engineered Automobile Crashes UCLA article, Paul Niquette, 1957
		A twenty-four channel recording oscillograph mounted in the instrument truck photographed information from tensiometers on the seat belts, as well as the accelerometers mounted on the various parts of the car and dummies.
		Synchronizing the high-speed camera with the oscillograph was accomplished by putting a strobe light on the car within range of the camera.
		The pulse thus generated was transmitted to the oscillograph through a small cable dragged by the truck.

		However, a successful by-product of his television work was the cathode ray oscillograph, a device that serves scientists as an X-ray machine serves doctors.
		The oscillograph, among other things, can measure the performance of an electrical circuit, the compression in diesel engine cylinders, the pitch of musical notes, and the strength and resiliency of a metal.
		With the broadening of the oscillograph market, Dr. Du Mont's progress was swift.

		A tracking device was constructed "to simulate roughly the display characteristics and control requirements of an airborne radar intercept mission".
		A control system involving a control stick and rudder pedals as in a standard aircraft control system was manipulated by the subject to control a target dot in the centre of a cathode ray oscillograph, and a needle of a voltmeter was used a side-slip indicator.
		The 203 subjects had to defeat an induced movement of the dot so as to keep the dot in the centre of the oscillograph.

		The most important parameters for accuracy of measurement and writing speed af cathode-ray oscillographs are the diameter of the writing spot and its energy density.
		To produce small and bright writing spots, the electron beams emerging divergently from the cathode had to be concentrated in a small writing spot on the fluorescent screen of the cathode-ray oscillograph.
		Not wishing to be accused of showmanship, Max Knoll and I agreed to avoid the term electron microscope in the lecture Knoll gave in June 1931 on the progress in the construction of cathode ray oscillographs where he also, for the first time, described in detail my electron-optical investigations [9, 10].
