Abstract: 287,921. Maschinenfabrik Augsburg- N³rnberg Akt.-Ges. March 30, 1927, [Convention date]. Sluice gates are operated by two or more motors which can be put into operation successively, and impart to the sluice different operating speeds, or act on sluices of different effective areas. The Figure shows a sluice g controlled by a float a by means of a lever c and electric contacts e, f. The contacts e are made by slight variations of water level and energize a motor l, which drives the shaft k and moves the gate g. The contacts f are made by greater movements of the float a, and energize the motor m, which, through a differential gear n, rotates the shaft k and moves the gate g more rapidly. A third motor, similarly controlled, may be fitted and the additional motors may be geared to different shafts k to operate additional gates.

[Class 135] A fluid-actuated valve comprises a casing with inlet and outlet ports 6, 7, respectively, a cage 9 provided with a seat for a main valve 19, a piston 21 reciprocable in the cage and connected to valve 19 by a tubular stem 20, a spring-pressed pilot valve 27 contained in the stem 20 and seating against the main valve, and a bleed port 40 which allows the inlet fluid to flow into, and build up pressure in, a chamber 41 above the piston. When a shaft 31 in the lower part of the casing is rotated, a cam 36 on the shaft, raises a push rod 32, and the upper end of the rod pushes open the pilot valve and allows the fluid in chamber 41 to flow to exhaust through the hollow stem of the main valve. This release of pressure on the upper surface of piston 21 allows the inlet pressure acting on the lower surface of the piston to push open the main valve. The main valve will be kept open by the actuating rod 32 when a shoulder 32" on the rod contacts the lower end of the valve, and as this will close the passage through the stem and the valve, an aperture 44 is provided to allow fluid to flow from the interior of the stem to exhaust. Bleed hole 40 may be situated in the piston. Cage 9 is adjustably screwed into the casing and is secured by a lock-nut 11, circular packing rings 16 housed in grooves in the cage sealing the joints between cage and casing. The pilot valve may be actuated manually or from an electric or other, prime mover.

Abstract: 1,131,965. Telegraphy. SIEMENS A.G. 19 Jan., 1967 [20 Jan., 1966], No. 2792/67. Heading H4P. In a telegraph exchange comprising a line KV having a plurality of channels, a unique combination of which is marked by each bit from any calling subscriber T1-Tn, there is a matrix unit SP having its rows Z1-Zn connected to the subscribers and its columns S1-S5 to the channels. The channels may be lines as shown or separate frequency channels. When subscriber T1 wishes to transmit, a calling signal passes via TS1 to unit ES which marks a combination of channels unique to the calling subscriber. This combination sets up a row of magnetic cores Zr associated with a free register R. Register R stores the combination. Dialling pulses from T1 then pass via TS1, ES, line KV, and Zr to the register, where the number of the called subscriber is now stored. The register selects by way of TSn the row Zn of the core matrix Sp corresponding to the called subscriber and sets the selected row to respond to the calling subscriber combination. The register is now released. Subsequently data from T1 passes via TS1, to ES, line KV and the selected row Zn to subscriber Tn. By selection of a plurality of rows a plurality of subscribers will receive the signals from T1.

Abstract: 1,073,461. Analyzing liquid mixtures electrically. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 27, 1965 [Jan. 27, 1964], No. 3467/64. Heading G1N. The ratio of two liquids in a mixture is determined by noting the dielectric constant, using the mixture as the dielectric of a capacitor in a tuned circuit and measuring the resonant frequency. As shown (Fig. 1), a sealed metal tube 11 with a central electrode 17 and filled with a reference liquid, is surrounded by a second metal tube 13, electrode 17 and tube 11 forming a reference capacitor and tubes 11, 13 with the test liquid as dielectric forming a test capacitor. Each capacitance forms a tuned circuit with half of a coil 18, and the two resonant circuits are fed with A. C. of cyclically varying frequency via coil 22. The voltage induced in a pick-up winding 23 is minimum when either circuit is resonant. Thus the time between resonances in each cycle of frequency scanning is indicative of the difference between the capacitances, dielectric constants and mixture ratios. Non-linearity is the variation of dielectric constant of the mixture can be compensated by suitable variation in the rate of change of frequency during the scanning cycle.
