Title: Improvements in or relating to travelling wave tubes with crossed electric and magnetic fields
IPC: H01J25/44
Filed: 1956-07-03
Abstract: 795,090. Travelling wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 3, 1956 [July 25, 1955], No. 20642/56. Class 39(1). In a travelling wave tube designed for crossed electric and magnetic fields the negative electrode 1, Figs. 1, 2, parallel to or concentric with the delay line is formed of resistive material with a loss angle of 45 degrees in the operating band and is connected to a biasing battery by a connection extending along its entire length so as to maintain its entire surface equipotential despite being struck by electrons from the beam. This impingement would normally cause generation of noise in the circuit connected to the negative electrode, particularly in high power tubes. As shown, the negative electrode 1 is carried in a peripheral groove in a metal support 2 supported by a metal disc 13 secured to three insulating rods 14, and its thickness is equal to or several times the skin depth. The resistivity of negative electrode 1 may be 50-1000 ohm.-cm, and the noise in the circuit to 1 due to electrons striking 1 is a minimum when p = 9À10#/E.W., where p = resistivity of material, e = dielectric constant, w = 2nf, the loss angle being 45 degrees. For h = 10 cm., p = 50 ohm.-cm. the skin depth is 6À5 mm. Collector 9 and screen 10 for decoupling the input 5 and output 6 may be integral, as shown, and the focusing electrode 8, which is positive to the cathode 7, is secured to the envelope by insulating supports 16. The invention can be applied to other types of travelling wave tubes of the crossed electric and magnetic field type, such as forward or backward wave amplifiers or oscillators of circular or linear type.

Title: A method for the vapour phase synthesis of vinyl acetate
IPC: B29B13/00
Filed: 1960-06-14
Abstract: <PICT:0910087/III/1> Vinyl acetate is synthesized by the vapour phase reaction of acetylene and acetic acid in a fluidized catalytic reaction apparatus 1 wherein the reaction temperature is controlled by regulating the temperature of the starting material entering the reactor in response to the variation of the reaction temperature so as to maintain the reaction temperature substantially constant. In one method of operation, the starting material mixture 3, comprising acetylene gas from a blower and acetic acid vapour from an evaporator, is passed through a cooler or preheater 4 and a by-pass 5 in parallel and the proportion which passes through either path is regulated by valves 6 and 61 controlled in response to variations in the reaction temperature whereby the temperature of the starting material mixture entering the reactor is adjusted so as to maintain the reaction temperature substantially constant.  In the apparatus shown, in which the reactor is large, two instruments 7 and 8 form a compound controlling system in which 7 measures the internal temperature (a) of the reactor 1 and will give a command to 8 corresponding to the variation of temperature whilst 8 will measure the temperature (b) and operate the valves 6 and 61 to make temperature (b) vary by an amount equal to the command given by 7. In a smaller apparatus, the instrument 7 can be used to control 6 and 61 directly.  The catalyst may be powdered active carbon impregnated with zinc acetate and dried.ALSO:<PICT:0910087/IV (b)/1> Vinyl acetate is synthesized by this vapour phase reaction of acetylene and acetic acid in fluidized catalytic reaction apparatus 1 wherein the reaction temperature is controlled by regulating the temperature of the starting material entering the reactor in response to the variation of the reaction temperature so as to maintain the reaction temperature substantially constant.

Abstract: 1,034,085. Drying webs. SINGER CO. May 17, 1965 [May 18, 1964], No. 20841/65. Heading F4G. In a tenter drying apparatus for fabric webs, e.g. carpets, the web C is transported through the drier by tenter chains 19 and has heated air directed therethrough of diminishing temperature from the entry end to the exit from the discharges 63 of outputs 60, 59, 58 of pairs of blowers in three-drying zones. The air passes through the web in each zone into a chamber 66 divided in each zone by a partition 69 into recirculating and discharge portions 71, 70 of respectively two-thirds and one-third of the size of the chambers. The discharge portion 70 is connected by a duct 81 to the next preceding zone via the input side of the blower and a heat exchanger 65 in which input it is mixed with the remaining two-thirds of the air recirculated in that zone from the portion 71 via a duct 80. In operation, the drying air initially is used in the final zone and enters through an exposed portion 82 of the exchanger 65 from hollow walls of the drier and the final portion of air from the discharge portion of the first drying zone is exhausted to atmosphere through a blower 72 and exhaust duct 75.

Title: Improvements in gear shaving
Inventor: BOHLE FRED
IPC: B23F21/28
Filed: 1955-07-19
Abstract: 817,423. Gear-finishing. ILLINOIS TOOL WORKS. July 19, 1955, No. 20908/55. Class 83(3). A gear-shaving tool 1 comprises an involute gear in which each tooth is cut off at one end by a surface intersecting one side of the tooth in a cutting-edge approximating the locus of successive points of contact of that side of the tooth with the sides of a conjugate gear on a skew axis. The tool is used in an attachment to a lathe. The attachment has a slide 22, Fig. 8, traversable by a hand wheel 30 connected to the lathe feed-screw 20. The slide 22 slidably supports a shaft 34 carrying a workpiece 36, Fig. 11, and connected to the lathe spindle 14 by a coupling 42. The shaving-tool 1 is also mounted on the slide 22, and is rotated in unison with the work through bevel and change-gears. The tool and the work-gear are secured to their shafts by keys and nuts, the shaft axes containing an angle of 15 to 60 degrees. The changegears 60, 64 include two gears of different helical angles on a common shaft 62 so that, by axial adjustment of the shaft by a screw 116, the tool may be adjusted angularly to increase or decrease the depth of cut. When the tool has finished one side of each tooth, the gear is turned end-for-end, and the opposite sides are finished. In a machine for shaving both sides of the teeth of a gear in one setting, the gear 158, Fig. 14, is rotated through a shaft 146 by a motor 124, which also rotates a traverse-screw 164. The cutter consists of two spaced sections 176, 178, Fig. 6. The cutter is moved axially, to bring a section into operative position, by a lever 188 rocked by penumatic means 198, 200. To adjust the cutter for different diameter gears, a cutter carriage 186 is movable transversely by a screw 208. The cutter can also operate on the opposite side of the gear, thus allowing a choice of helix angles. The drive to the cutter is from the shaft 146 via a slotted member 244, a follower member 243, and gearing 212, 220. As the gear is traversed, the follower moves along the slots in the member 244 and imparts an additional movement to the cutter to modify the helix angle of the gear, or to crown the teeth. The shaving-edges may be formed on carbide inserts 3, Fig. 4. A further modified cutter 248, Fig. 7, has cutting-edges at each end. The helix-angle of the cutter-teeth may be slightly modified to increase the cutting-effect, and the cutting-depth increased at the ends of the teeth to crown them. Tip and root relief may be provided by increasing the curvature of the end surfaces of the cutter-teeth.

Class 75(4) [Also in Group XX] A lamphouse unit for a projector comprises a holder for a high pressure gas discharge lamp, a main mirror and an auxiliary mirror separately mounted on two parallel spindles supported by the front and rear walls of the housing, the main mirror being fixed on a bridge across the spindles, and the lampholder and auxiliary mirror being carried on slides independently movable along the spindles. As shown in plain view in Fig. 2, spindles 10, 11 are supported in bearings 8 and 9 at the front and rear walls of the housing and are held against axial movement by screws 12. Mounted on the spindles is a bridge 15 held against axial movement during rotation of the spindles by screw 17.
