Title: Telephone systems
IPC: H04Q3/42
Filed: 1940-02-03
Abstract: 537,751. Automatic exchange systems. WESTERN ELECTRIC CO., Ltd. (Electrical Research Products, Inc.). Feb. 3, 1940, No. 2160. [Class 40 (iv)] Each digit is sent from a substation as a single pulse of alternating current the frequency of which indicates the. place of the digit, its value being indicated by the position of the pulse in a time interval during which all the digits are sent. As shown the number is selected by operating switches 105 .. 111 which connect generators f1 .. f 7 to selected terminals in the respective banks of a distributer. Button 133 is then pressed and the hand-set is removed whereupon a register controller is seized in known manner and supplies current from a generator 232 to synchronous motors driving the sub-station distributer and a receiving distributer in the register controller. As a result, a relay in each of seven groups similar to that shown at 202, is energized, and energizes appropriate relays in a four-relay register, Fig. 4 (not shown), which controls the setting up of the connection in known manner. When the sending distributer has made a complete rotation it releases button 133 and stops. The receiving distributer in this position energizes a relay 231 which disconnects the generator 232. In a modification the transmitting distributer is driven by a spring under governor control. In a further modification a constantly running synchronous motor is permanently coupled to the distributer by a slipping clutch.

Title: Regulation of forced through flow steam generators
IPC: F22G5/00
Filed: 1957-01-21
Abstract: 831,209. Regulating forced flow steam boilers. SULZER FRERES S. A. Jan. 21, 1957 [Jan. 24, 1956], No. 2172/57. Class 123(2) Forced throughflow steam generators operating at high, maybe supercritical pressures are regulated in the event of a change of load by first regulating the output of the generator to suit the changed load without directly adjusting the generator steam pressure by adjusting the supply of at least one of the operating media, that is, the fuel, combustion air or feedwater and thereafter adjusting the steam pressure to a value corresponding to the new load. The generator shown in the Figure has a preheater 2, an evaporator 3, a superheater 4 and a reheater 5. Feedwater is supplied through a regulating valve 6 and the generated steam passes to the plant turbine through a pipe 8 provided with a regulating valve 51. Fuel is supplied through a pipe 10 having a valve 9 and combustion air through a pipe 12 having a valve 11. The settings of valves 6, 11, 9 are respectively and simultaneously adjusted when a change of output is desired, by operation of a handwheel 16 of a control device 13, the handwheel rotating a shaft 17 carrying cams 18, 19, 20 until an indicator 31, also driven by the shaft, registers the new load. The movement of the cams is transmitted, for example hydraulically, to the valves to cause them to open or close by the appropriate amount. The steam output which has thus been increased or decreased is ascertained by a flowmeter 34 which, by means of a transmission device, brings the pointer of an indicator 32 to a position indicating that the new output has been attained, the pointer position then corresponding with that of the indicator 31. The boiler steam pressure and the steam temperatures of superheat and reheat are now brought to values associated with the changed output by operation of the handwheel 38 of the control device until its indicator 72 is in the same position as that shown on the indicators 31, 32. Rotation of the wheel 38 adjusts the position of cams 40...43, the movement of the cam 40 effecting, for example, through a hydraulic transmission device, the required alteration in the setting of the valve 51 to bring the boiler pressure to the value corresponding to the new load, the movement of the cam 43 altering the datum setting of a thermostat 69 disposed between the evaporator 3 and superheater 4, this setting influencing the supply of feedwater, and the movement of the cams 41, 42 respectively altering the datum settings of thermostats 53, 61 respectively controlling the attemperating water injection into the superheater and reheater for the control of the steam temperatures at the outlets therefrom.

Convention date, Jan. 23, 1933. [Class 40 (iii)] In four - terminal networks for filtering, simulating cables and other purposes, the requisite number of elements is reduced by coupling the series arms of a T- or H -section to a reactance comprising two or more elements and having an infinite value for direct currents. The mutual inductance may take the form of a coil 16 with a load a linking the series arms 14, 15, Fig. 1, the shunt arm comprising a suitable impedance b ; or a balanced form of this arrangement may be adopted, Fig. 3, (not shown) ; or the series arms 38, 39 may be directly coupled, Fig. 4, and Figs. 2, 5, 6, (not shown), the load a, comprising the parts 35, 36, 37, in Fig. 4, being shunted across one of them, 38. In any case the impedance of the load a must not be zero for direct current. Networks of the kind described may be connected in parallel or series, Figs. 7, 8, (not shown), for operating currents of different frequencies. The coupling between the series arms may be loose or tight. The invention is shown as applied to filters of Cauer classes 3b, Fig. 4, 3b<*> Fig. 5, (not shown), and 3d, Fig. 6, (not shown).

Abstract: 174,607. Mihßly, D. von. Dec. 9, 1920, [Convention date]. Selenium cells.-Relates to a method for constructing selenium cells, and to forms of holder in which a cell is mounted. The cell comprises electrodes a, b, Fig. 1, each made up of thin steel strips insulated by mica sheets c, which are split under high pressure to ensure uniform thickness. In order that the edges may be parallel, the plates are assembled and ground in a hardened steel shaping box, and then taken apart and smoothed at the edges. Finally they are reassembled and ground in a longitudinal direction only, coated with amorphous selenium, and heated in a thermostat chamber. One formof holder comprises a metal block d, Fig. 2, in electrical connection with the electrode b of the cell which is inserted in the recess e. Insulating layers g, hare slipped over the projections f, the electrode k passing through a gap i in the layer h. A metal shell l is then fastened to the projections f by insulated screws m, and preferably soldered at the electrode k. The use of metal' mountings avoids the troubles which would be caused by unequal coefficients of thermal expansion. In another form of holder, metal jaws n, o, Fig. 3, are clamped over the cell by screws p, insulation q, q being provided. In a further form, the screws p are absent and the jaws n, o are held together by insulated side-pieces. The Specification refers to a known type of cell in which bifilar wires are wound on a porcelain, lardite, or lardstone body; to another in which a thin deposit of silver or platinum is divided by a zigzag interslice; and to another in which two insulated thin metal strips are wound together.
