Title: Regulating device for the control of diesel-electric and turbo-electric units
Inventor: FINTESCU NICOLAE DAN
IPC: B60L50/10
Filed: 1961-01-17
Abstract: 930,812. Automatic speed control. MINISTER FOR THE RUMANIAN MINISTRY FOR HEAVY INDUSTRY. Jan. 17, 1961, No. 1947/61. Class 38 (4). [Also in Group XXVII] In a regulating device for fuel supply and speed control in diesel-electric or turbo-electric engine units, a slidable cylinder 1, in a housing 2, is connected to the fuel supply control linkage and contains a potentiometer driving member 6, controlled by an engine governor to regulate the excitation of the generator by adjustment of a wiper 3b on the potentiometer 3. The desired governor speed setting and fuel supply rate are simultaneously set at an external control (not shown) to give corresponding positions of the member 6 and, by means of cam 8 abutting a stop 8b, the slidable cylinder 1 which carries the potentiometer 3. The cam 8 is journalled on a shaft 8a and is moved by lever 7, rod 10, and spring 10 by means of an electrical, pneumatic, or mechanical servo mechanism. With increase of load in the electrical circuit the engine speed falls off and the speed governor moves member 6 to the left to rotate the wiper 3b towards the terminal 3e. This results in diminished generator excitation to maintain a constant engine speed, and in a similar manner the generator excitation is increased with a reduction in electrical circuit load. With movement beyond the range of wiper arm movement i.e. at full load or idling, the ends of rack member 6 contacts either the blind end of cylinder 2 or the internal face of sleeve 9 to control the fuel supply without causing a change in the generator excitation. The voltage or current between terminals 3d and 3c is amplified and feeds the generator excitation winding. Limitation of the maximum current and voltage or of the maximum excitation of the generator is effected by end switches acting on the excitation amplifiers.

Abstract: 509,618. Delivery arrangements for water heaters. AMUNDSEN, I. Jan. 24, 1938, No. 2303. Convention date, Jan. 23, 1937. [Class 64 (i)] [Also in Group XVII] In order to retain the hottest part of a liquid of varying temperature flowing through a conduit, a container is connected to the conduit in such a manner that when the liquid flowing in the conduit is lighter than the liquid in the container it will pass into the container and replace the heavier liquid therein. The invention is applicable for collecting the hot portion of the cooling water passing from an intermittently operating absorption refrigerator. As shown in Fig. 1, a conduit 6, through which liquid passes to a waste outlet 9 is connected by pipes 4 to the upper and lower ends of a container 1. When the water flowing through the conduit 6 has a lower specific gravity than that in the container, it will pass into the container through the inlet 2 and heavier water will be returned through the outlet 3, to the pipe 8 and outlet 9. Hot water can be drawnoff from the container through a perforated pipe 13, extending to the upper part of the container, and a cock 12. The container 1 and pipes 4 may be heat-insulated. Fig. 2 shows an arrangement of two containers 14, 15 connected to one another by a pipe 18 and so connected to the conduit system that the hottest water will be collected in the container 14 and water of a lower temperature in the container 15.
