Wire or rod reeling apparatus includes a rotating laying tube through which wire or rod is fed to be laid in a worm thread which rotates with the laying tube, the wire or rod issuing from the laying tube being inclined towards a wall of the worm thread. A laying tube 63, carried by a rotating frame 64, directs wire W into, and towards the trailing wall of the thread of a worm 65 secured to the frame 64 and enclosed by a casing 66. The pitch of part of the wall of the worm thread is adjustable. In another embodiment, Figs. 3, 4 (not shown), the laying tube directs the wire towards the leading wall of the worm thread and the outlet end of the laying tube is adjustable in inclination. The pitch of the worm may decrease in the conveying direction. The worm thread may be multi-start. The turns of wire issuing from the worm thread may be carried away by three endless conveyer belts, 85, Fig. 5, or by a plurality of worms spaced around the periphery of the wire turns. The wire turns are checked and tripped by an abutment 89 to fall into a collecting vessel 86. The apparatus may be vertically instead of horizontally arranged. In a further arrangement, Fig. 6 (not shown), turns are carried by inner endless conveyers (107), (108) co-operating with an outer conveyer (105) and are turned over by passage up a guide (109) to fall into a collector (106). In another arrangement, Fig. 7 (not shown), the turns are tripped by a member (119) as they issue from the worm thread (114) to fall on to a conveyer (115) thence to pass to a collector (116). A simple shoot or cam wheel or chain may replace the member (119). Alternatively the turns may be allowed to fall directly on to a slowly moving conveyer.

Title: Apparatus for evaluating holographic interferograms
IPC: G01B9/021
Filed: 1974-02-12
Abstract: 1432893 Holographic interferometry BBC BROWN BOVERI & CO Ltd 12 Feb 1974 [14 Feb 1973] 06290/74 Heading G1A In the investigation of an object which is deformed from one state to a second state, holographic interferometry, involving phase investigation of an interferogram of the two states, is utilized. In Fig. 1(a), a first hologram H of the object O 1  in its first state is formed using an illumination beam B(wo) of frequency wo and a reference beam R 1 (w 0 ) of the same frequency. The object is deformed (02) and illuminated at a second frequency (w2) by beam B(w 2 ), the scattered radiation and a reference beam R 1 (w 1 ) of a third frequency w 1 , being used to illuminate the hologram H, and form two wavefronts B 1 (w 1 )and B 2 '(w 2 ) which are superimposed to form an interferogram at plane E. The intensity of the image at a given point in the plane E oscillates at the beat frequency of the second and third frequencies w 1  and w 2  and the phase of these oscillations is investigated using optoelectronic detectors F 1 , F 2  (e.g. photodiodes). The former is fixed in space and provides a reference phase; the other is scanned across the interference fringes and is connected to circuitry to count fringes and to interpolate between them so providing information as to the deformation of the object O. In a second method, Fig. 2 (not shown) two exposures are made on the same hologram using same frequency w o  for illuminating and reference beams. The object is deformed between the two exposures and the reference beams are spatially different for the two exposures. The developed hologram is reconstructed using reference beams of the same respective spatial characteristics as the first reference beams, but of different frequencies w 1 , w 2 . In a third method, Fig. 3 (not shown), the two holograms of the object are formed while both in position one behind the other, the reference beams being applied sequentially to their respective hologram. In the second and third arrangements, the interfering wavefronts may be produced individually by the use'of only one reference beam R 1 (w 1 ) or R2 (w 2 ) at any one time. The object may be oscillating when in the second state. The reference and illuminating beams may be derived via beam-splitters, mirrors, mechano- or electo-optical modulators etc. from the same laser. Alternatively, a two frequency (Zeerman) laser or two different lasers may be used. Derivative signals may be obtained in arrangements utilizing an array of three or six detectors, coupled to a plurality of phase meters, enabling surface strain characteristics to be investigated, Figs. 4, 5 (not shown).

Title: High-frequency valve transmitters modulated by anode control
IPC: H03C1/20
Filed: 1949-03-08
Abstract: 658,684. Valve modulating circuits. SOC. INDEPENDANTE DE TELEGRAPHIE SANS FIL. March 8, 1949, No. 6336. Convention date, March 12, 1948. [Class 40 (v)] In a carrier modulating system, the signal is fed in phase opposition to two Class B amplifiers, the respective output voltages of which occur alternately and are fed, one to the cathode, and the other to the anode, of the carrier stage. Current of signal frequency is thus caused to flow through the valve or valves of the carrier stage, its path to earth being completed by two diodes or other unilateral conductors which are alternately rendered non-conducting by the fall of voltage on the anode of the active Class B amplifier. As shown, the signal voltage S is applied in pushpull to the grids of cathode-follower valves 24, 25 which feed the Class B amplifiers 22, 23. H.T. supply 19 for these valves is fed through a smoothing circuit 17, 18 and individual choke coils 16, 26. They pass current during alternate half-cycles of the signal voltage, and a fall of voltage occurs alternately at their respective anodes. The carrier stage comprises a pair of valves 1, 2 fed in push-pull by the input circuit 5 and with the carrier output circuit 3 connected to the H.T. source 19 through the signal choke 26. The cathodeearth circuits of the valves 1, 2 include individual bias elements 8, 9, a signal choke coil 20, and a shunted bias resistor 21. Positive bias is thus provided for the anodes of diodes 27, 28 and in the absence of modulating-signal these diodes are conductive. During one half-cycle of modulation, the fall of voltage at the anode of the valve 22 blocks the diode 27 and during the other half-cycle, the diode 28 is blocked by the fall of voltage at the anode of valve 23. The voltage changes at the anode of the valve 23 are fed directly to the anodes of the carrier stage, and the signal current path through the carrier valves 1, 2.is completed on the cathode side by the diode 27. During the succeeding half-cycle, signal voltage is fed from the anode of the valve 22 through a capacity 34 to the cathodes of the carrier valves and the signal current path is completed on the anode side by the condenser 35 and diode 28. The choke coils 20, 45, which prevent signal current from passing from the anodes of the valves 22, 23 to earth through the capacity 44, may be wound on the same cores as the choke coils 16, 26. The modulating system is contrasted with the known system in which transformer coupling is provided between the Class B valves and the carrier stage, and the Specification includes a discussion of the known system, Figs. 1, 2a, 2b (not.shown).

IPC: H01J9/04
Filed: 1929-02-27
Abstract: 306,960. Loewe, B. Feb. 28, 1928, [Convention date]. Vacuum tubes.-In the manufacture of thermionic valves, barium, calcium or strontium is liberated to activate the cathode by effecting within the valve a chemical reaction which causes the metal to be vaporized and deposited on the cathode. In an example, powdered silicon and barium oxide, formed into a tablet, with the addition, if necessary, of an agglutinant, are so introduced into the valve that heat may be applied thereto while connected to the pump. The reactive materials may be mixed with a retarding agent, which may be one of the reaction products. Silicon may be replaced by ferro-silicon. A tablet of the materials is secured inside the anode, or in a. capsule which is mounted at the side of the electrode system, and heated by electron bombardment or by high-frequency currents. The Specification as open to inspection under Sect. 91 (3) (a) states also that sodium, potassium and other metals may be deposited by the method described and that deposits of different metals may be produced successively or simultaneously. Aluminium or magnesium may be employed as the reducing agent and the mixture to be decomposed may be applied to the surface of the cathode. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 296,781.
