Title: Remote control system as applied to diesel generator sets
IPC: F02N19/00
Filed: 1954-06-18
Abstract: 784,400. Starting and stopping prime-movers. BROGAN, P. J. June 15, 1955 [June 18, 1954], No. 18004/54. Class 38 (4). Relates to a remote control system for starting and stopping an electric generator set driven by a diesel engine, the generator having starter windings 8 incorporated therein. A fuel control lever 6 is spring-loaded into the position, and an engine decompressor lever 2 is likewise biased into the position of full compression. When the engine is running and it is desired to stop it, a control button 10 is depressed for a short period and then released. Upon closure of the electromagnetic switch 9, a solenoid 1 does not operate since it is subjected to the difference of the voltages developed by the starter windings and by battery 7. The solenoid 5, however, receives the high backelectromotive force of the windings 8 and operates against spring 11 to suspend fuel injection, an interlock 4 retaining the lever 6 in the " stop " position. To start the engine, the control button is again depressed for a short period, so that closure of switch 9 energizes windings 8 and solenoid 1 decompresses the engine. The device 4 is actuated by cable 3 to release the lever 6 which is spring-returned to the " run " position against the effect of the solenoid 5. In an alternative arrangement, the solenoid 5 is sufficiently powerful when the engine is being started to operate against the spring 11. The lever 6 is then held in the " stop " position until the button 10 is released. A frame or box carrying the solenoids 1 and 5, as well as the interlocking device 4, may be mounted on the engine, cables being provided to couple the lever 2 to the solenoid 1 and lever 6 to the solenoid 5, Fig. 1 (not shown). A shunt may be provided for the coil of solenoid 1 to relieve it of part of the heavy starting current. When starting under cold conditions, the engine is motored under full compression for a short period. For this purpose, a relay responsive to a predetermined value of generator voltage is adapted to short-circuit the solenoid 1 and return the lever 2 to the " full compression " position when the crankshaft reaches its normal starting speed, Fig. 2 (not shown).

Filed: 1919-07-18
Abstract: 157,490. Broadbridge, W., Edser, E., and Minerals Separation, Ltd. July 18, 1919. Recovering fats and oils from waste waters.- Liquid or semi-liquid suspensions in liquids are treated in froth flotation apparatus of standard type used in mineral ore concentration, for the separation of certain constituents, such as wool fat from wool-washing waters. In the apparatus shown in Fig. 3, and which is of the type shown in Specification 21650/13 and described in Specification 155,349, [both in Class 82 (ii), Washing granular &c.], the wool-washing water from the inlet M is beaten by the agitator L below a series of grids O while air is admitted through a pipe N; the minute air bubbles rise through a zone of liquid maintained comparatively quiescent by baffles P and form froth on the surface which overflows to the launders Q. The liquid in J flows out for retreatment in one or more similar apparatus, and the temperature during treatment is preferably 25-30‹ C. In the apparatus of Fig. 1 the liquid poured into the vessel A is thrashed by the agitator B of the kind described in Specification 22743/12, [Class 82 (ii), Washing granular &c.], and aerated by indrawn air; it passes through a passage C to a spitzkasten D and the froth overflows to the launder E. The liquid in the spitzkasten is sucked through the pipe G partly for retreatment in vessel A and partly to the next vessel A in series. Materials may be added to modify the liquid before treatment, for example, the viscosity may be reduced by water, or dilute acid or alkali, or the formation of froth may be assisted by soap, saponin or amyl alcohol for example; and undesired constituents may be prevented from flocculating and so being separated by the froth by addition of suitable deflocculating- agents. Specifications 6671/88, 2320/92, 18239/95, 3819/03, [Class 1, Acids, alkalies, &c.], 28057/07, 17644/08, [Class 111, Sewage &c.], 22743/12, [Class 82 (ii), Washing granular &c.], 5754/13, 15799/14, [Class 111, Sewage &c.], 23741/14, and 18023/15, [Class 111, Sewage &c.], are referred to.
