Title: Improvements in or relating to indicating devices
Inventor: MOSS ERIC BEECROFT
IPC: G01P3/46
Filed: 1947-11-14
Abstract: 654,168. Electric speed indicators. SMITH & SONS (ENGLAND), Ltd., S. Nov. 14, 1947, No. 30350. [Class 40 (i)] An electric indicating device comprises an indicator responsive to electric signals representing a variable, in circuit with a relay which is also responsive to the signals to modify the indicator circuit and thereby alter the range of magnitudes of the variable to which the indicator is responsive. In an electrical speedometer, an A.C. or D.C. generator 10 (Fig. 1), is driven in accordance with the speed, e.g. of a locomotive and its output varies accordingly. A current or voltage measuring instrument 12 indicates the speed and is connected in series with the generator through a resistance 13 normally shorted out by the contacts of relay 17 connected across the generator. At low speeds the instrument 12 registers in its most sensitive condition but at a speed corresponding to its full scale deflection, relay 17 operates and inserts series resistance 13 so that the instrument indicates speed on a second range with a higher maximum reading. In a modification (Fig. 2 not shown), a first generator is connected to the indicator at low speeds until full scale deflection is reached, when a relay is operated by the second generator (which has a lower output than the first), to connect the second generator to the indicator, instead of the first, giving a second speed range with a higher maximum reading.

Abstract: <PICT:0924591/III/1> In the pyrolysis of hydrocarbons by contact with a combustion gas the combustion is effected by injecting, into the combustion chamber 1, fuel and oxygen or an oxygen-containing gas through one or more sets of annular concentric nozzles 10 and 11 (Fig. 1) inclined so that the gases, injected at speeds of 50-350 m./sec. meet at an angle of 40-90 degrees to form a cylindrical flame, the combustion gases are passed through constriction 11, where the hydrocarbons are injected, into the reaction chamber 2, and the reactants are cooled.  More than one set of nozzles may be used as shown in Fig. 4.  Oxygen is preferably injected through the inner nozzle (11) and may be given a rotary motion by means of a helical guide in the annular feed pipe 4.

Title: Improvements in or relating to travelling wave devices
Inventor: DIX CYRIL HENRY
IPC: H01J25/38
Filed: 1960-09-06
Abstract: 919,867. Travelling-wave tubes. M-O VALVE CO. Ltd. Sept. 28, 1961 [Sept. 6, 1960], No. 30666/60. Class 39 (1). A travelling-wave tube comprises a delay line having a series of resonant cavities separated by discs, each cavity being magnetically coupled to at least one other cavity in the series via a path comprising at least one further resonant cavity not forming part of the series, the magnetic and electric coupling between adjacent cavities being of the same phase. There is a coupling aperture in each resonator for this purpose. The resonator walls carrying the coupling apertures may be flat. Preferably but not necessarily the coupling resonators form further delay line(s) of further travelling- wave tube(s), e.g. there may be three or four travelling-wave tubes in parallel with separate electron beams. One of the delay lines has one extra resonator (the one carrying the main input and output connections). A cylindrical electromagnet may focus the beam or beams. The magnetic and electric fields in adjacent cavities differ in phase by 180 degrees by suitably dimensioning of the coupling discs. The cavities of the other delay lines may be similarly coupled to the cavities of the first delay line. When there are more than three travelling- wave tubes in parallel, they may form a honeycomb structure. There may be more than one coupling aperture in each disc.

[Also in Divisions B3 and F2] A device for conveying elongated workpieces 1 axially past a processing station 21 comprises two parallel transport devices 2, 3, one of the transport devices 2 moving a workpiece axially in direction A past the station 21 whilst the other transport device 3 returns empty in the opposite direction B to receive a fresh workpiece. Each transport device comprises at least two spaced apart transport vehicles, 4 and 5, in the case of transport device 2 and 6 and 7 in the case of transport device 3. and each vehicle has at least one workpiece support arm 8, 9, 10, 11 that is pivotable about a perpendicular or horizontal axis and is adjustable in the vertical direction. Fig. 1 shows how the arms 10 and 11 have been swung to an inoperative setting whilst the empty transport vehicles 6, 7 move in direction B. The arms 8 and 9 are shown in their operative setting whilst the loaded transport vehicles 4, 5 move in direction A. The elongated workpieces 1 can thus be moved successively along a common axis. The spacing between the transport vehicles 4 and 5 is adjustable by means 12. Similarly the spacing between the transport vehicles 6 and 7 is adjustable by means 13. The empty transport vehicles return at a speed higher than when loaded. Each of the support arms 8, 9, 10, 11 comprises a pair of rollers 14, 15, 16, 17 on which a workpiece can rest. At least one roller of each pair is driven and the driven roller may have a toothed profile. The distance between the rollers constituting a pair is adjustable. The apparatus may be used to convey tubes 1 past a synthetic material extruder 21 so that each tube is wound with a tape of the extruded synthetic material, the tube having been previsously coated with an adhesive. This adhesive can, during the same operation, be likewise wound around the tube in the form of a tape from a further extruder. To ensure that the synthetic material coating is cut off at the end of each tube the rollers 14, 15, 16, 17 have rims (18), Figs. 4 and 5 (not shown), in the form of roller cutters (20), these cutters serving to cut through any of the coating which extends beyond the end of the tube.
