Patent GB-687149-A (GB)
Title: Microwave amplifiers
IPC: H01J25/587
Filed: 1950-01-10
Abstract: 687,149. Magnetron amplifiers. STANDARD TELEPHONES & CABLES, Ltd. Jan. 10, 1950 [June 25, 1949], No. 593/50. Class 39(i) A magnetron of the multi-cavity type is modified by making a helical cut 6, Fig. 1, in the anode structure so as to divide it into a plurality of cavity resonators arranged in a helix about the elongated cathode 1, end plates 10, 11 are provided between which a DC field is set up to give the electrons a helical path, and input and output coaxial lines 18, 19 are coupled to the end resonators by loops 16, 17 so that the device functions as an amplifier. The device operates on travelling wave principles, the helically moving electrons travelling at the same velocity as the helically travelling wave and the DC potential between plates 10, 11 being adjusted so that the pitch of the electron paths equals the pitch of the resonator slots. To prevent field interactions between adjacent ends of end-to-end resonators, an edge wound metal strip 7 is threaded into the helical cut, and a second strip 14 may be moved longitudinally by dielectric rod 15 passing through bellows to the exterior for tuning. The cathode 1 is indirectly heated and has a helical emissive coating as shown to confine emission to the spaces opposite the resonator slots; it is supported at either end by leads 8, 9. Local feedback between resonators may be reduced by roughening the resonator surfaces to introduce resistive losses or by choosing anode material of low specific conductance. To increase the gain, positive regeneration may be employed e.g. by feedback through transmission lines which are adjustable for regulating the amplitude and phase of the feedback energy.

Title: Tube winding machine
Inventor: BYRNE WILLIAM EDMUND WIDDRINGT
IPC: B21C37/12
Filed: 1951-01-12
Abstract: 676,076. Making tubing. TITEFLEX, Inc. Jan. 12, 1951, No. 982/51. Classes 83 (ii) and 83 (iv). Angular bending; coiling; soldering; seaming.-In making helically seamed non- circular tubing from strip material a preformed strip is wound helically on a rotated non-circular mandrel by an oscillated flat guide and the seam is compressed by rolls. A strip 19a is fed through a lubricating bath 63 and rolls 65, which bend the strip to the section shown in Fig. 12, to a mandrel 22 rotated by an electromotor 29. Flat inclined guide plates 23 are carried on a lever 34 and seaming rolls 24 are journalled in a lever 36. The levers are connected by a spring 25 and mounted on a pin 35. As the mandrel rotates the levers are oscillated against spring pressure by extensions 45, 59, which contact the mandrel to lessen the friction on the strip. A strengthening wire and a solder wire may be wound with the strip. The inclined guide plate 23 engages the preformed strip and co-operates with the mandrel to effect the coiling, positions the strip edges for seaming and effect the forward feed of the coiled tube. The seaming rolls loosely mounted for limited longitudinal movement are shaped to position the strips and to seam the joint.

Namely, the pressure below 1/2 the minimum tensile strength value for not producing the flare, e.g., 0.15kg/cm 2  or less is applied thereto between the temperature at which the outside surface of the joint 2 becomes red heat by this heating and when the inside surface of the joint part 2 reaches 1300°C. When the temperature of the joint part 2 reaches 600°C or more, the pipe outside surface becomes red heat state. Next, when the pipe inside surface of the joint part 2 reaches the correct temperature for welding start of not reaching the melting point and above 1300°C, pressing pressure is applied to the pipes 1, 1'.

Filed: 1978-01-07
Abstract: PURPOSE: To simplify the working of the aperture of a test chamber thereby to meter and monitor the film thickness at a low cost by using the light emanating from the inside of the test chamber as a light source.  
     CONSTITUTION: A test chamber 1 is formed with an exhaust port 2, a gas inlet 5 and an aperture 3 for taking out the light to be metered. There are mounted in the chamber 1 an evaporation source boat 4, a high frequency plasma exciting coil 17 and a platform 6. There are arranged outside of the chamber 1 an optical filter 19, a light receiving element 20, an electroc-control device 21, and a recorder 22 connected thereto. Since, in this instance, the exicted light of the evaporated particles 18 in the chamber 1 is used as a light source, the intensity of the light becomes proportional to the evaporation of the substance. As a result, the evaporation can be monitored in terms of the intensity of the light having the waveform of a recorder, and the thickness of the film 7 formed can also be calculated.
