Haematometharmozograph is a ten-dollar name for a simple two-hundred dollar contrivance made from an electric light bulb, a photoelectric cell and an oscillograph. On the principle that fear constricts small blood vessels in the fingers, prevents blood from freely circulating through the hands, Dr. Thompson rigged up an apparatus which would indirectly show whether blood vessels were constricted by measuring the amount of light which passes through a person's hand...
...Thompson's descriptions of fearful accidents. The more frightened the patient, the more translucent his hand. Light passing through the patient's fingers controls the amount of current generated by the cell. The current is transmitted to an amplifier, and the amplified current activates an oscillograph (an instrument which records sound or light waves on a sensitized film) or a pen recorder...
...department concerns itself largely with the theory of metals and alloys based on the study of the crystalline structure through application of X-ray diffraction technique and microscopy. Recently Dr. Hultgren has developed a cathode ray oscillograph apparatus for the measurement of the position of X-ray diffraction lines recorded on photographic film. This apparatus permits the position of the diffraction lines to be measured with great accuracy and rapidity, and is proving a valuable tool in the determination of the distances between the atoms in metallic crystals. These distances are of the order of the hundred millionth part...
...correct way to estimate the capacity of the shops is to examine their products. In Pierce Hall is a Cathode Ray Oscillograph machine which measures a movement taking place in forty-millionths of a second, the first high-voltage transmitter in the country, and massive soil testing engines whose four foot beams are knife-edged to the accuracy of a thousandth of an inch...
...liner drew close it steered slightly to port of the lightship and speed was reduced to 16 knots. The oscillograph detector was not used to find the distance, but the liner's position was computed by cross-bearings from shore radio stations. Few minutes before the crash, while the beacon indicated the lightship to be three degrees off the starboard bow, the signals were suddenly lost. The oscillograph detector went dead also. Then the lightship's fog whistle was heard. Every officer on the Olympic's bow agreed the sound was off the starboard bow. To play...
