Title: Impulse turbines
IPC: F03B1/04
Filed: 1923-03-13
Abstract: 209,989. Moody, L. F. March 13, 1923. Axial-flow type ; jet-wheels ; reflexed-flow type ; vanes.- In an hydraulic-impulse turbine. a solid cylindrical jet J, Figs. 2 and 3, of variable diameter is directed tangentially to the vane-wheel but at an angle to the plane of the wheel. The water enters through a circular pipe P, Fig. 2, of decreasing cross-section having branches p<2> leading to nozzles A. The jet impinges on vanes B<1> of the horizontal wheel W and passes axially therethrough. The vanes B<1>, are substantially of straight-line cross-section transverse to the direction of flow and are concave in the direction of flow the curvature decreasing progressively away from the wheel axis, as shown in Fig. 3, to correspond with the varying rotational velocity. The wheel-shaft S is supported in a babbitted or lignum-vitae bearing B supported by arms M in a pit T, the shaft S passing upward tu a power-generator. In the jet wheel shown in Fig. 14, The variable jet J<1>, which is shown in the plane of the wheel may impinge on the buckets B<1> at an angle to the said plane, giving rise to reflexed flow. The angle between the jet axis and the plane of the runner-wheel is preferably greater than 40‹, the normal linear velocity of the buckets greater than one half that of the jet and the jet diameter greater than one fourth the radial distance between the axes of the jet and the wheel. Working-fluid supply ; nozzles ; regulating.- The water entering the pipe p<2>, Fig. 2, passes through an annular intake passage A, through a cylindrical radially-directed opening 0, and is then turned substantially at right angles to form a solid cylindrical jet .T. The jet may be varied in diameter by a fluid-operated plunger 21 or a fluid-operated variable by-pass d for slow and quick regulation respectively. The jet regulating devices may be on either side of the flow, and may also operate both on the same side of the flow. The plunger 21 and the by-pass d act upon the flow at a point where it is strictly radial, so that the diameter of the jet varies directly in accordance with the linear movement thereof. In a modified form of nozzle water entering through an intake 40, Fig. 16, passes through two halfvolutes surrounding a two-part plunger 43, 44 and forms a main and an auxiliary jet J, j. For slight variations in the jet, the main plunger 43 is moved to the right by fluid pressure operating through ports 48, 49. For sudden large variations the plunger is moved as a whole the slow water-saving adjustment being made by expanding the plunger. In a further modification, the flow passes radially inwards between adjustable vanes 60, Fig. 17. to form the jet which passes through a fixed deflector plate 55 to the buckets. Alteration of the angle of the vanes 60 expands the jet, part of which is cut off by the plate 55.

Abstract: 1422556 Ultrasonic inspection devices V DEUTSCH [trading as PRUF-UND MESSGERATEBAU KARL DEUTSCH] 15 Feb 1973 [16 Feb 1972] 7611/73 Heading H4D The intensity, and reception time relative to the transmission time, of a received ultrasonic pulse are displayed by activating a series of optical display units in turn following the transmission, comparing the intensity with at least one reference signal to produce at least one comparison signal, and using the latter to cause the activated unit or units to emit light so that a display representative of the pulse envelope is obtained. The invention is applicable to ultrasonic pulseecho or through-transmission systems for non- destructive testing or medical diagnosis. To provide a histogram-type display of received pulse intensity against pulse propagation time, lamps, liquid crystal devices, or light-emitting diodes are arranged in rows and columns, the columns are successively energized during the propagation, and the number of lamps &c. illuminated in any column is made dependent on the received pulse intensity. This dependence is achieved by use of a respective voltage comparator for each row, the comparators having respective different associated threshold voltages against which the received signal is compared. The increments between the threshold voltages may be in a linear or logarithmic series, and may be varied, e.g. to give a display which compensates for attenuation of the ultrasonic pulse in its propagation through a test object. Output signals from the comparators may also be used for automation purposes such as operating markers, print-out recorders or sorting devices. A shift register, or counter with decoder, is used to provide the successive energization of the columns. An additional display comprises a single row of elements in which numbers are displayed.
