Title: Improvements relating to forced recirculation steam generators
IPC: F22B37/70
Filed: 1958-01-13
Abstract: 861,583. Valves. VORKAUF, H. Jan. 13, 1958 [June 24, 1957], No. 1176/58. Class 135. [Also in Groups XIII, XXVI and XXXV] A forced recirculation steam generator of the type (not illustrated) in which the working medium is circulated through the heating surface in quantities in excess of the evaporation by means of a constant-speed centrifugal pump which draws water from a steam and water drum and delivers it to the heated boiler tubes, is provided with a regulating or throttling device arranged in a suction or delivery pipe of the water circulating pump and adapted to operate in response to variation in " water condition," so to regulate the water flow as to maintain the power consumption of the pump at an approximately constant level, the term " water condition " being defined as the pressure and/or corresponding temperature of the water in circulation at any operating condition from cold start-up until full boiler operating pressure is reached. Three forms of the device are shown in Figs. 1, 2 and 3, respectively. In Fig. 1, a throttling gate member 4 in the suction or delivery pipe 1 of the pump is spring-loaded in the direction to throttle the flow and the water pressure has direct access past this member to an actuating-piston 3, so that the throttling effect is lessened and flow increased as the boiler pressure rises, thereby maintaining the power consumption of the pump approximately constant. At full boiler pressure, the piston 3 can seat itself on a seat 7 and prevent the leak-off of boiler water through a pipe 6 which otherwise functions as a drain connection. In Fig. 2, a butterfly throttle valve 9 in a pipe 8 of the pump is responsive to water temperature, being actuated by an expansion bar 11 pivoted to the valve 9 at 12 and to the pipe 8 at 13, this bar having a higher linear expansion than the pipe so that on rise of temperature the valve opens to lessen the throttling effect, and again the power consumption of the pump is kept constant. It is stated that the valve 9 and expansion bar 11 may be fitted in separate pipes through which the working medium is circulated, the two members being connected together through a linkage. In Fig. 3, the pump is driven by an electric motor (not shown) and a throttling- member 14 in the suction or delivery pipe is actuated through gearing 16 by a reversible electric motor 17, in response to variations of power current supplied to the pump driving motor, this current acting through a coil 18 on an armature 20 against a spring 19 to make and break alternately contacts 21, 24 and 22, 23, respectively, in the circuit of the motor 17 so that a fall in power consumption as the boiler temperature or pressure rises results in a reduction of throttling by the member 14 to increase the flow, and vice versa, whereby the power consumption is again maintained at an approximately constant level.

Filed: 1957-01-16
Abstract: 805,515. Waveguides. COMPAGNIE GENERALE DE TELEGRAPHIC SANS FIL. Jan. 16, 1957 [Jan. 26, 1956], No. 1644/57. Class 40 (8). [Also in Group XL (c)] A frequency-separating arrangement comprises a hollow waveguide dimensioned and positioned with respect to a source in such a manner that waves of a certain frequency F1 propagate on the external surface of the guide and waves of higher frequencies F2, F3 ... Fn propagate in the interior of the guide. Waves of all frequencies F1 ... Fn are launched by a horn 1 and thence propagate along a dielectriccovered conductive rod 2 aligned and coaxial with the flared mouth of a circular waveguide 4. Waves of the higher frequencies F2, F3 ... Fn propagate along the inside of the guide 4 to a terminal coupling 13 whilst those of the lowest frequency F1 are supported by a transmission line constituted by the external surface of the guide 4 and spaced, conductive annuli 3. This transmission line is surrounded by a shortcircuited waveguide 6 coupled to a pair of orthogonally disposed rectangular waveguides 10, 11 whereby horizontally and vertically polarized components of the low frequency signal may be separated. Separation of any number of signal channels may be achieved by using a corresponding number of such arrangements in cascade. The dielectric coating of the rod 2 may be replaced by a propagating structure such as that surrounding the waveguide 4 and the structure around the waveguide 4 may be replaced by a dielectric coating. The invention may be applied to communication systems in which the transmitted and received signals use the same antenna but are polarized at right-angles to one another.

Title: Improvements in tape advancing machines for use in connection with type-printing telegraphs
IPC: G03B21/134
Filed: 1930-01-17
Abstract: 347,179. Feeding webs. NEWS PROJECTION CORPORATION, 60, Broad Street, New York, U.S.A.-(Assignees of Eitzen, A. D. ; 60, Broad Street, New York, U.S.A.) Jan. 17, 1930, No. 1716. Convention date, Feb. 7, 1929. [Class 100 (i).] In an arrangement for projecting on to a screen the legend (such as stock quotations) on the tape emerging from a printing telegraph, the tape is moved intermittently at intervals determined by the accumulation o f (ontinuously - fed slack. The tape 15 passes through the optical projection apparatus 11, Fig. 1, and is normally held at both ends by the fingers 26, 17, respectively. The finger 26 is released during rotation of the feeding device 57 by energization of the solenoid 28 through two brushes 89 which are bridged by a contact-piece 84 (Fig. 5, not shown) while the finger 77 is disengaged from the tape by the action of the cam 73. The tapefeeding device is released when the slack 15a, Fig. 1, has accumulated sufficiently to close the switch 34, 37. The solenoid 71 thereupon lifts the latch 67 and so clutches the free sleeve 57 to the continuously rotating drum 53 as described below. The sleeve 57 then performs one revolution carrying with it the arm 61 which ultimately engages the latch 67 again so as to release the clutch. During the revolution the end 51 of the coupling-rod 50 performs a simple harmonic motion. It first pulls the double-armed lever 47, 48 to the right, so that the roller 49 on the shorter arm 48 grips the tape 15 by pressing it against the platform 45 (Fig. 6, not shown). The rod 50 then pulls to the right the tape and the platform, which is rigid with guides 41 sliding on a rail 40, a friction spring 43 insuring the engagement and disengagement of the roller 42 with and from the tape. The simple harmonic motion involves the gentle application of tension to the tape. At each movement the tape is pulled through a distance equal to half the length of the exposed part thus each quotation is exhibited twice (Fig. 9, not shown).
