Title: Improvements in or relating to the automatic frequency regulation of alternating current supplies
IPC: H02J3/08
Filed: 1934-03-20
Abstract: 440,635. Automatic reversible motor regulators. GENERAL ELECTRIC CO., Ltd., Magnet House. Kingsway, London, and GIBSON, J. W., c/o General Electric Co., Ltd., Witton, Birmingham. March 20, 1934, No. 27347 /35. Divided out of 436,574. [Cla.ss 38 (iv)] The frequency of an A.C. generator is controlled by means responsive to integrated frequency error and means responsive to the load demand of the generator are arranged to exert a control tending to prevent alteration of frequency as a result of variation in the load demand. The frequency of an A.C. generator is varied by a reversible motor 54 acting on the engine governor under the control of contactors 49, 50, which are operated by " raise " and " lower " segments 40, 41 on a drum switch 38 which is rotated by a synchronous motor 29 driven by the generator. The brush 44 coacting with a continuous segment 39 on the switch 38 is energized from supply 19 through contacts 14 of a telephone relay which are closed intermittently by a master clock 3 so that when the frequency is correct the contacts of relay 14 are not closed when brushes 45 and 46 are on their respective segments 40, 41. Positive or negative integrated frequency error causes contacts 46, 41 or 45, 40 to be closed at the same instant as contacts 14 are closed thereby to control the governor motor 54 to decrease or increase the speed of the prime mover. The arm carrying the brushes 44, 45, 46, 47 of the controller 38 is adjustable in accordance with the position of the governor through the medium of torque motors 59, 60 and the arrangement allows of an integrated frequency error dependent upon the generator loading. This ensures suitable load sharing between parallel connected generators. An intermediate torque motor 73 is inserted between the motors 59 and 60, which is controlled in accordance with the generator load from a repeating watt meter 77 so as to prevent alterations in frequency as a result of variations in the load on the generator. Lock out contacts 42, 43 on the controller 38 effect control of warning or protective devices when the integrated frequency error exceeds a predetermined value. Interlock contacts 51, 52 are provided on the contactors 49, 50. Specification 407,401 is referred to.

Abstract: 446,338. Calculating - apparatus. BROIDO, D., 74, Belsize Park Gardens, London, and HAUSMANN, R., Ibiza, Spain. Sept. 25, 1934, No. 27436. [Class 106 (i)] A method of and apparatus for combining two or more variable factors and for transmitting the result to a registering mechanism consists in modifying a light-ray as by changing its position, shape, or intensity so as to act on a single light sensitive element forming part of the registering mechanism, which mechanism on a rotative movement or succession of movements being imparted thereto is variably affected in accordance with the manner in which it has been modified. In one embodiment as applied to the multiplication of two factors, an opaque screen 1, Fig. 1, is divided into a number of areas each of such areas being provided with a number of translucent or reflecting spots or slots representing the partial products of the digits multiplied by themselves. The screen as shown in Fig. 2 is formed as a hollow cylinder on a shaft 3 mounted in bearing and capable of being displaced axially as well as rotatively. A source of illumination such as a lamp 9 is mounted in the interior of the cylinder. The registering mechanism consists of a hollow transmission cylinder 13 housing a light-sensitive cell 15 and formed with a row of slots 14, Fig. 3, spirally arranged thereon and secured to a shaft 19 journalled in bearings 20, 21 and 22 and provided with a pin 30 adapted to engage grooves 31 in one or other of the registering wheels 32, 33, 34. The shaft 19 is urged towards the left by a spring 24 co-operating with a pin 23, but is held against movement by a pin 25 engaging one of the grooves 26 in the shaft. The pin 25 is pivoted to a lever 27 forming the armature of an electromagnet 39 arranged in circuit with the light sensitive cell 15. When the factors have been set by the rotation and axial displacement of the screen 1, the shaft 19 is rotated by the handle 44 and the pin 30 effects the rotation of the units wheel 32 until one of the slots comes directly in front of the image of the translucent spot representing the units value of the partial product whereupon the cell 15 is affected and the magnet 39 is energized to attract its armature 27, thus withdrawing the pin 25 and permitting the shaft 19 to move to the left until the pin 30 comes against the face of the tens wheel 33. Rotation of the shaft 19 is continued to complete one cycle of movement, whereupon the pin 30 enters the groove 31 in the tens wheel and the pin 25 snaps into the next groove 26. A second cycle of movement causes the tens value of the partial product to be entered into the tens wheel 33. Various modified forms of screen, optical systems, and apparatus are described.
