Title: Improvements in or relating to electrical filters and impedance transforming networks
IPC: H03H2/00
Filed: 1938-01-20
Abstract: 514,298. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., RUST, N. M., and 0'NEILL, .R. F. Jan. 20, 1938, No. 1939. [Classes 40 (iii) and 40 (v)] A tapered line whose impedance-transformation ratio is approximately independent of variation in the terminal load is suitable for coupling a feeder'to an aerial and comprises sections composed of pairs of inverse halfsections, which produce equal and opposite phase shifts at a frequency within the working range. Fig. 1 shows a tapered line in which the sections are matched at the logarithmic midband frequency. Alternatively they may be matched at two frequencies other than the midband frequency, Fig. 2 (not shown). At these frequencies the transformation ratio of the line is independent of the terminal loads. One or more pairs of inverse half sections may be used for matching a coaxial feeder F to an aerial array or aerial. The reactance of the aerial may form part of the terminal arm of the tapered line, Fig. 14 (not shown). The section may be unbalanced like those shown in Fig. 1 (Figs. 3, 4, 7, 16, not shown), or balanced (Figs. 5, 16, not shown or one half section may be balanced and the other unbalanced, for connecting an asymmetrical feeder to a symmetrical aerial (Fig. 6, not shown). Where the shunt-terminated end of the transducer (Fig. 8, not shown) is terminated in its image impedance, such as that of the long-wave aerial A1, or short-wave aerial A2, Fig. 10, the input impedance at the other end, such as that terminated by the feeder F, becomes very high outside the cut-offs, so that each aerial is prevented from short-circuiting the other. When, on the other hand, the series-terminated end of the transducer (Fig. 9, not shown) is matched by its aerial, the opposite end exhibits a very low impedance outside the cut-off frequencies ; the input terminals of the two transducers are then connected in series to the feeder, Fig. 11 (not shown). In order that the tuning of a receiver may not be affected by variation of the impedance of the aerial, the receiver-end impedance of the feeder is freed from reactance by connecting the aerial to the feeder through a tapered line of the kind described; the aerial impedance being treated as an element in the tapered line. The aerial may be connected to earth through a resistance which forms the terminal shunt arm of the line, Fig. 12 (not shown) ; or three aerials, serving three different ranges of frequency, may be so connected to three tapered lines which are connected through a further tapered line to the feeder.

Abstract: 1,165,181. Partial accelerators. SCIENCE RESEARCH COUNCIL. 6 Jan., 1967 [14 Jan., 1966], No. 1976/66. Heading H1D. In a separated orbit cyclotron comprising an alternating series of electromagnets 1, Fig. 2, and radio-frequency excited cavities 2 disposed in a closed ring, the cavities are excited by one or more pulsed electron beams 5 circulating outside the spiral path followed by the accelerated beam 3 of e.g. protons. The widths of the portions 6 of the cavities through which the electron beams pass are the same but to allow for decrease in beam velocity the relative locations in azimuth of the portions vary and the beams are guided by magnets 7. The beams are coupled to the cavities at zero phase angle relative to the electric field and cavities 8 operated at a high harmonic of the frequency of the cavities 2 are provided to reduce energy dispersion. The electron beams are introduced with relativistic velocities and are generated in apparatus comprising a plurality of electron guns 10, Fig. 3, with modulating grids 15 and a plurality of D.C. linear accelerators 12. The high voltages applied to the accelerator electrodes are developed by a high-voltage generator 17 as described in Specification 1,165,182. The voltages developed across capacitors are applied between pairs of accelerator electrodes common to all the accelerators. Quadrupole focusing magnets 31 are provided between some of the accelerator electrodes. A proton beam may be accelerated successively in a linear accelerator and three separate cyclotrons of increasing energy. In the lower energy cyclotrons the electron beams are circulated at half the synchronous radius and the cavities are spaced such that the proton beam is accelerated once every two cycles of the radio-frequency.

Title: Improvements in safety tackle hook
IPC: B66C1/36
Filed: 1945-01-30
Abstract: 589,500. Hooks. HOFFMAN, R. Jan. 30, 1945, No. 2363. Convention date, June 7, 1944. [Class 89 (ii)] A safety tackle hook comprises a clevis having a transverse bar bridging the lower end of the arms, a pivot mounted in said arms to pass freely through an elongated slot in the shank of a hook so that a lip on the point of the hook can be engaged with or disengaged from the transverse bar, and means for limiting the movement of the hook in its open position. The clevis 11, Fig. 1, has parallel arms 13 each having a thickened elbow portion 15 having holes 16 for a pivot pin 25, Fig. 3, which has a shoulder integral at one end and an opening 26 for a pin 27 at the opposite end. An elongated slot 24 in the shank of the hook 20 is rounded at each end to fit the pivot pin so that the pivot is slidable in the slot and enables a lip 23 on the hook to engage or disengage the bar 14 bridging the lower end of the clevis arms. Raised shoulders 28 on each side of the shank of the hook co-operate with raised surfaces 17 on the inside of each clevis arm. The surface 17 on the clevis has a radius 18, Fig. 5, concentric with the pivot hole adjoining a straight portion 19 and corresponding surfaces 29 and 30 are formed on the hook. A surface 31 concentric with the lower end of the slot is also formed on the hook to adjoin a straight portion 32 which abuts a shoulder 33, Fig. 5, on the clevis to limit the extent to which the hook may be opened. Should the pivot break or fall out when the hook is closed, the lip 23 and surfaces 18 and 19 and 29 and 30 co-operate to prevent the hook opening; these surfaces together with the bar 14 and lip 23 also share the load on the hook relieving the strain on the pivot.

Filed: 1957-01-23
Abstract: 871,957. Protective cut-out arrangements. ENGLISH ELECTRIC CO. Ltd. Jan. 15, 1958 [Jan. 23, 1957], No. 2428/57. Class 38 (5). [Also in Group XL (c)] To minimize the effect of D.C. offset in the A.C. signals derived from a protected circuit and applied to a protective relay system, a comparator provides a relay-operating output in response to the combined effects of two polarity coincidence detections. In Fig. 2, the A.C. signals IZ-V and V are applied to the bases of transistors 20, 21. Each of these transistors is connected with a series resistor combination as shown and the circuit constants are such that on the appropriate half-cycles of the applied signals when transistor 20 is non-conductive and transistor 21 is conductive, the potential of junction P4 is greater than that of junction P1 so causing a transistor 22 to conduct. At the same time, the potential of junction P3 is greater than that of junction P2 so that a transistor 23 is non- conductive. On the other half-cycles of the applied signals the transistors 20, 23 conduct and the transistors 21, 22 are non-conductive. When both transistors 20, 21 are conductive or non-conductive, neither transistor 22 or 23 can conduct, so that the output signal derived as a potential drop across a resistor 30 is only present when the signals IZ-V and V are of opposite polarity, the duration of the output signal per cycle being proportional to the phase difference between the A.C. signals. Electromagnetic switches, thermionic tubes or transductors may be used in place of the transistors.

Abstract: 294,444. Siemens & Halske Akt.-Ges. Oct. 12, 1927, [Convention date]. Track apparatus actuating signals on trains.- In apparatus for controlling signals or other apparatus on a train by the interaction of a traincarried magnetic system energized by alternating currents in circuits including inductance and capacity with a track magnetic mass wound with a coil shunted by a condenser and a semaphoreoperated switch, the locomotive system comprises two or more circuits so coupled that iron masses beneath them produce a strengthening of the coupling. Fig. 13 shows a locomotive system comprising two cores wound with exciting windings 36, 37 supplied by a generator 1 and receiving windings 38, 39 supplying the relay 2. When running between signals the relay is energized. At a line-clear signal, the switch 24 being closed, capacity 23 is short-circuited and a magnetic flux is created in the track core 20 and passes through cores 34, 35 but is not sufficient to produce any operative, change in the relay coil 2. At a danger signal, the switch 24 is open and the resonant condenser 23 causes the production by the coil 22 of a large flux in the cores 20, 34, 35, so that the resultant flux acting on the receiver coils 38, 39 is zero or approximately zero and the relay 2 is de-energized. The degree of coupling of the excitation and receiver circuits on the locomotive may be varied by connection yokes 51, 52, Fig. 17, or by a single yoke near the mid-point of the length of the cores. An alternative construction of locomotive magnets is shown in Fig. 18. This comprises only one core 4 with a closing yoke 58 arranged over it. The exciting windings are the coils 53, 54 on the main core and the coil 57 on the yoke. The receiving winding 55 is placed between the ends of the yoke. Alternatively the exciting winding may replace coil 55 and the other coils in series may be used as receiving coils.
