Title: Improved process and apparatus for the manufacture of liquid sulphurous acid from dilute sulphurous acid gas
IPC: C01B17/60
Filed: 1919-12-02
Abstract: 159,337. Pascal, P. Dec. 2, 1919. Gas solutions, distilling. - Sulphur dioxide is obtained from dilute gas mixtures, for instance gases from the roasting of blende and pyrites by treating the gas mixture under pressure with a carbolic oil obtained by distilling coal tar at 175-225‹ C., and separating the dissolved gas by heat and reduced pressure after which the gas is liquefied. The dilute gas is compressed by a compressor 1, and delivered by a pipe 2 to a packed tower 3 supplied with oil by a pump 4 through a pipe 5. The issuing gas is expanded in an expander 6 and.led by a pipe 7 to apparatus for recovering the last traces of sulphur dioxide. The oil passes from the bottom of the tower 3 by a pipe 8 to a coil 9 in a heat exchanger 10 having a jacket 11 supplied with steam and thence is delivered by a pipe 12 in a tangential jet into an expansion chamber 13 having a steam jacket 14. The oil collecting in the lower part of the expander 13 is heated by a steam coil 16, from which the steam passes through the jacket 11 of the exchanger 10. The oil from the expander 13 passes through the exchanger 10 through a coil 20, in a cooler 21 and thence to the pump 4. The sulphur dioxide separated in the expander 13 passes up a plate tower 24, which separates oil vapour, to a suction pump 25 after which it is liquefied.

Title: Improvements in or relating to electrical signalling systems
Inventor: CLARK ADRIAN PERCY
IPC: H04Q1/448
Filed: 1961-08-22
Abstract: 976, 292. Electric selective signalling. BRITISH TELECOMMUNICATION RESEARCH Ltd. Aug, 17, 1962 [Aug. 22, 1961], No. 30297/61. Addition to 905,433. Heading G4H. In a binary signalling system in which one value is represented by a phase change of 180 degrees between successive sine wave signals and the other value by no change (W1, Fig. 2) the signals are delayed by half the length of one signal element and the direct and delayed signals are compared to detect changes, signal elements being thereby produced at twice the frequency of the incoming signals with alternate elements all having the same value. In the form described the incoming signal elements each comprise two cycles of A.C.; "1" is represented by a phase change and "0" by no change. The direct and delayed signals, W1 and W2 are clipped and amplified to form square waves W3 and W4. These are compared in a modulus 2 adder giving a negative signal when the inputs are the same and a positive signal when they differ as shown at W5. This wave is delayed and inverted by a low pass filter (giving wave W6) and a slicer to produce wave W7. The complement of this wave is differentiated to give W8 and applied to a ringing circuit of a fixed frequency. The output (W9) is squared (W10) and applied to a stroke generator which gives clock pulses W11. These are applied to an output toggle to sample the wave W7 and produce a two-state output as shown at W12. The zeros which occur between adjacent data elements are thereby eliminated.

Title: New or improved controlling means for the forward and reverse transmission gearing of marine engines
IPC: F16H3/00
Filed: 1932-10-29
Abstract: 408,357. Gear - changing mechanism. BENDIX, Ltd., CLARK, H., and WYNNE, C. H. L., King's Road, Tyseley, Birmingham. Oct. 29, 1932, No. 30368. [Class 80 (ii).] Forward and reverse transmission gears are provided with vacuum or pressure gear-changing devices which are automatically disconnected when the gear is engaged. Preferably the gearing comprises a pair of combined cylinders controlled by a hand-actuated valve which couples either cylinder with the atmosphere or a source of vacuum or pressure. A valve 15 is interposed between a pipe 35 connected with the induction pipe 36 of the internal-combustion engine and a space 7 in a cylinder unit which is divided into chambers 2 and 3. Pistons 4 and 5 are secured to a solid rod 8 and hollow rod 9 respectively and these in turn are connected with a gear-changing shaft. The control of the valve is effected by a hand lever 37 which may also embody the control of the engine throttle valve, and which in addition is connected by a forked member 39 with a double dog clutch 47 adapted to couple levers 48, 49 that are connected with the rods 8, 9 respectively to a shaft 43 carrying a quadrant 44. The quadrant 44 meshes with another 45 freely mounted on a shaft 41 which is the actual gear shifting member. The quadrant 45 is continued in the form of a lever 46 which projects between jaws on a lever 50 which is attached positively to the shaft 41. Upon the valve 15 being moved one or other of the pistons 4 or 5 moves the corresponding rod and the respective dog coupling 47 is engaged. By the time the gear has actually changed, the quadrant 44 has overrun quadrant 45 and the gear shift is thereby disconnected. In the event of hand operation being required, the lever 50 is withdrawn free from the lever 46 against the action of a spring 55 and its jaw members engaged with a projection upon the hand operating lever 42; at the same time the relay system is isolated by a valve 34.

Filed: 1954-10-25
Abstract: 755,311. Telemetering. LANDIS & GYR AKT.-GES. Oct. 25, 1954 [Oct. 23, 1953], No. 30674/54. Class 40(1) The invention relates to tape recordings in which a record strip R, Fig. 1, is moved forward by two superposed independent drives, a zero feed which advances the strip at a constant speed a fixed distance a 0  during each constant duration measuring period La-L1, and the power feed which advances the tape a varying amount a 3  during the measuring period. The measuring periods are separated by marks La, L1, &c., and a mark L2 indicates the end of a day's recordings. The invention is concerned with transmitting successively measured values a 1  to respective registers which each integrate the measurements made during their respective measuring periods at a plurality of measuring points. For this purpose the day record strips produced at the various stations are successively passed at constant speed through the integrator, Fig. 2. As each mark La, L1, &c., is scanned, contacts T1 close to energize a relay A which energizes the drive magnet SM to step a selector switch W to connect the next meter ZW in circuit, stops the motor M driving the record strip, and energizes a slow-to-operate relay B, which de-energizes A to energize a timing relay ZR and restart the strip drive motor M. After a predetermined time corresponding to the zero feed a 0 , the relay ZR closes contacts ZR1 so that the selected meter (counter) ZW is driven by a constant speed motor ZM for the remainder of the measuring period, i.e., for a time proportional to the measured value a 1 . When the next mark is scanned, relay A operates as before to step the selector W to the next meter ZW and the cycle is repeated. At the end of a day, scanning of the mark L2 closes a contact T2 to hold relay A operated and stop metering until a button D is operated.
