NEW TO ASSIST YOU
CHINESE BIBLIOGRAPHY An extensive bibliography of the petroleum geology of the People's Republicof China -- the first to be compiled in more than 30 years -- has been published by Philip A. Chenoweth, Tulsa consulting geologist. The bibliography, which is partly annotated, lists more than 200 publications and articles on general geology, stratigraphy, tectonics, geophysics, production, reservoir studies, and sources rocks. The information was obtained from many sources, some obscure, some official Chinese, Russian and U.S. government documents. The publications referred to are mostly in English but some are in Chinese, Russian, and other European languages. The China bibliography may be purchased from Chenoweth & Associates, 702 Petroleum Club Building, Tulsa, Okla., 74119, U.S.A.
AUTOMATIC ERATOR
SEISMIC SHOCK GEN-
The new Soiltest Automatic Seismic Shock Generator produces the high-energy shock needed in seismic surveying of soils and rock. It greatly extends the range of most single-channel refraction seismographs. It may be moved about the survey site or operated in a central location. On its trailer mounting, the Soiltest Seismic Shock Generator is completely mobile for fast transport to the site, over the highway or off-the-roed. Drop height of the tamping plate ranges from 1 inch to 5 ft. Drop interval is adjustable from approximately 1 to 8seconds. Once the operator has determined the best operating height and interval, he adjusts the controls to repeat the shocks automatically as long as needed. Manual control also is possible. The quiet operation of the electric-powered shock generator makes it practical for saismicwork in remote and urban areas.

UNIVERSAL
TRANSMITTER
Philips has introduced a new universal solid-state transmitter for handling pH or mV signals in industrial applications where direct, on-site reading is not required. Designated the PW 9406 Universal Transmitter, it is said to combine the durability and simplicity of a conventional non-indicating pH transmitter with the versatility of a universal unit, at moderate cost, The new instrument will accept inputs from pH, pNa, pK, redox and other mV potantials, including those from ion-selective electrostatic charges. It can be set to measure over a span of pH 2, pH 5, or pH 1 0 . . . or 200 mV, 500 mY,or 1000 mV. Choice of zero values of pH 0, pH 2, pH 4 a n d pH 6 . o r 700 mV, 500 mV, 300 mV and 100 m V . . . gives the user a selection of twelve standard pH ranges and twelve standard mV ranges. Reversing the plug =vesanadditional twelve mV ranges of opposite polarity to the standard ranges. This is particularly useful for redox measurements. There are only two control knobs on the face of the instrument and power requirements are 100 V, 127 V, 220 V o r 240 V plus 12 V d.c. Its weight is only 1.9 kg and it is enclosed in a glass-fibre-reinforced case. For further details apply to: N.V.
