and adjustable compression soring. Pump zemains in full stroke position until pressure on plunger overcomes Control mechanisms for hydraulic pumps have been one of the primary factors in promoting the use of fluid power equipment. Fluid power equipment can accomplish Both linear and rotary motion, or any combination of the two. The effectiveness of present day control mechanisms enables fluid power to compete with mechanical or electrical equipment in performance, dependability, weight, adaptability, and price, regardless of the application.
JOURNAL OF THE FRANKLIN INSTITUTE The following papers will appear in the JOURNALwithin the next few months: BLANTON, H. ELMORE: Carrier Compensation for Servomechanisms. LEE, JAMES S. Y.: Interflection Tables for Rooms with Floors of High Reflectance. CHARLTON, T. M.: Some Notes on the Analysis of Redundant Systems by Means of the Law of Conservation of Energy. SILBERSTEIN, LUDWIK: Paucity of Quanta Rendering a Silver Halide Grain Developable. MooN, PARRY AND DOMXNAEBERLE SPENCER: Simplified Interflection Calculations. EISENBUD, LEONARD:On the Theory of Angular Correlation Phenomena. GRoss, ERIC T. B. AN~ LEONARD R-~BtNS: Transient Analysis of Three-Phase Power Systems. The January 1951 issue will be a special number, commemorating the 125th anniversary of the JouaN.~a.. In addition to the history of the JOURNAL, there will be fifteen papers by outstanding authorities on the subject of probable future developments in various branches of science and technology. The complete list of authors will appear in the December JOURNAL, together with the titles of their papers. If extra copies of thi s important issue are desired, write to the Assistant Editor stating the number you wish reserved for y o u - - t h e cost is one dollar per copy, payable either in advance or on delivery.
