Title: Improvements in or relating to electrical regulating systems for motor-alternators
IPC: H02P9/42
Filed: 1948-06-29
Abstract: 691,034. Automatic control systems for motor alternators. CLEVELAND, F. J. (Bendix Aviation Corporation). June 29, 1948, No. 17485/48. Class 38 (iv). In a motor-alternator frequency stabilizing system alternator speed is controlled in response to alternator frequency detected by a device including a resonant circuit, the system being rendered ineffective by a relay between a frequency corresponding to the resonant frequency and a predetermined higher frequency. A compound motor 9 when supplied from a D.C. source 1 drives an alternator, three-phase windings A, B, C of which normally supply a load (not shown) connected to terminals 18, 19, 20. Closure of a starting switch 2 energizes a relay 3 to complete the supply from the D.C. source to motor 9 and to alternator field winding 14. The motor starts with its shunt field. winding 12 connected directly across the D.C. source through contacts 8 of a relay 5. Alternator voltage is stabilized by a carbon pile 33 in series with the alternator field, the control coil 38 of the pile being connected to the alternator terminals through a rectifier 39. The motor armature is in series with its series field winding 11 and when, during starting, the motor reaches a predetermined speed, the rise of voltage across the armature operates relay 5 which closes contacts 7, 8 to connect the alternator load, and opens contacts 8 to insert a carbon pile 16 in series with the motor shunt field. Frequency stabilization is thus introduced since control coil 24 of carbon pile 16 is energized by the rectified voltage across the condenser of a resonant LC circuit 28, 30 connected to the alternator terminals and this introduction occurs at an alternator frequency above the resonant frequency of the LC circuit, which thereafter operates to stabilize frequency at a point on the high frequency side of its resonance curve. Specification 608,508 is referred to.

Abstract: 292,980. Ruthsaccumulator Aktiebolag. June 28, 1927, [Convention date]. Equalizing load on generator; running generators in parallel. - An electric power generating plant with two or more power services supplying a common network and sub-divided into services supplying the " base " load and the peak load comprises heat accumulating means associated with the latter the steam supply to which is controlled according to the speed of a peak load generator. The steam supply to the base load source is regulated according to the pressure or temperature of the steam supply thereto and speed regulators on the peak load machines. permit them to make up any deficiency in the supply from the base load source. A base load plant comprises a boiler K<1> fed with cold or hot water according to steam pressure &c. by automatic regulators W, M, a feed water heater S, supplied with condensate under the automaticcontrol of a steam pressure &c. regulator Rand a turbine controlled by a speed regulator Z, and an overflow valve V,. A peak load plant comprises a boiler K2 feeding a peak load turbogenerator under the control of a speed regulator Z2 and feeding also a heat accumulator S2 under the control of a steam pressure &c. valve V2. A second peak load turbo-generator is supplied from the heat accumulator through a speed regulator Zs. The arrangement is such that on rising load the steam condensation in the feed heater S, is first stopped, then the boiler K1, which is at first fed with cold water, is fed with hot water; next the fall in periodicity causes the valve Z2 to open and the peak load unit G2 to assume load the steam supply to the accumulator S2 is stopped, and the unit Gs is loaded. Meanwhile further steam is raised in the base load plant and as the steam pressure and periodicity rise the base load plant assumes more of the load and the peak load plant returns to its unloaded condition until the steam pressure falls again in the base load plant and the process is repeated.

Filed: 1922-06-30
Abstract: 190,994. Janik, W. Dec. 31, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Transmitting power.-A pneumatic rotary-cylinder variable speed gear for transmitting motion from a driving to a driven shaft is provided with a regulating sleeve valve and with an auxiliary reservoir for rotating either shaft when the other shaft is prevented from rotating. The driving shaft 25, Fig. 2, is connected to a casing 1 carrying a number of radial cylinders 3 enclosing pistons 2 mounted on a common crank shaft formed on the driven shaft 19. Passages 3<a> connect the cylinders to a valve casing 7 containing a sleeve valve 8, Figs. 6 and 7, the setting of which can be varied by means of a spirally grooved sleeve 20. In operation, the rotation of the cylinder casing causes air to be drawn into the uppermost cylinder through the port 10<a>, where it is then compressed and delivered into the channel 9. The pressure in the channel 9 increases until the gear functions and transmits the motion to the driven shaft 19. By means of the sleeve 20 the valve can be turned through 90‹ when the gear runs idly or to intermediate positions for intermediate ratios. By means of a valve 17, Fig. 5, and passages 15, 16, a reservoir 18 can be shut off from the gear or be connected through the passage 15 so as to be charged with compressed air or through the passage 16. The reservoir then serves for starting the rotation of the driving shaft 25 when the shaft 19 is prevented from rotating, or drives the shaft 19 when the shaft 25 is not rotating. In a modification, the valve 8 is provided with an auxiliary sliding valve. The valve 17 may be replaced by a pair of valves controlled by a rocking lever.
