IPC: H01J33/00
Filed: 1966-11-04
Abstract: 1,175,539. Electron beam irradiation apparatus. J. de S. MOSELY. 30 Oct., 1967 [4 Nov., 1966], No. 49571/66. Heading H1D. In apparatus for irradiating material with a scanned beam of particles, e.g. electrons, incident upon the material through a window, the scanning is produced by a beam-deflecting voltage of sawtooth form, the linear trace of which extends beyond each end of the window, and the flyback trace of which is either suppressed, or deflected away from the window. As shown, the beam passes through a window 5, mounted in the end wall of a stainless steel scan horn 3, and is thereafter caused by an electron lens system to diverge into a broader band 10 before impacting the moving or stationary material 11, e.g. a chemical compound to be cured. The window, of aluminium or titanium, is protected from overheating by air blowing and extracting manifolds arranged adjacent the window, and by arranging the beam source 2 such that the undeflected beam is displaced from the window and incident upon the hollow end wall 4, which is cooled by internal turbulent water flow and external fins. A square pulse is applied to electromagnetic or electrostatic deflecting means to ensure that the flyback trace is incident only upon the cooled wall 4.

The subframe is slidably mounted on bars 18 which extend transversely from the main frame 2. Two probes 40 between which the topped beet is allowed to pass as the machine advances are mounted on vertical pivots 42 at the rear of the subframe Misalignment of the topping apparatus relative to the row being topped produced by variations in the spacing from the said row to the adjacent row which is being lifted by the wheels 16, causes one of the probes to be displaced, this in turn operates a spool valve 38 which causes a hydraulic ram 34 to displace the subframe 20 transversely to the direction of advance until the topping apparatus is realigned with the row. In a modification Fig. 6, the probes 40 are mounted on horizontal pivots 41. Misalignment causes one of the probes to pass over the beet; the resulting vertical displacement is transmitted by a bell crank 56 to the spool valve 38.

When the apparatus is used for cleaning the parts of dismantled mechanisms the holder is mounted coaxially to be rotated only by the shaft 8, but when whole mechanisms are to be cleaned the holder is mounted eccentrically so that it is subjected to vibration during rotation. The coupling 9 comprises a plate 17 adjustable about a pivot 19 relatively to a plate 16 within limits determined by an arcuate slot in the plate 16 through which passes a screw 15 screwed into the plate 17. The plate 16 is secured to the motor shaft and the plate 17 has rotatably mounted thereon plates 20, 21 to the lower of which the mechanism holder is attached by a screw thread 24. The rotatable mounting of the plates 20, 21 causes them to rotate at a lower speed than the shaft 8.

Abstract: 516,000. Lactones. HUNSDIECKS, H., ERLBACH, H., and VOGT, E. June 13, 1938, Nos. 17513 and 17514. Convention dates, June 12, 1937, and Oct. 26, 1937. [Class 2 (iii)] Lactones particularly of large molecular weight are prepared from salts of halogenated fatty acids by heating the acid in the presence of an alkali carbonate in solution in a low boiling aliphatic ketone. The preferred acids for use as parent materials are halogenated keto fatty acids. The characteristic feature of the present invention is working in a heterogenous system, that is, using a solvent in which both the alkali carbonate and the halogenated fatty acid salts are insoluble so that the formation of the salt and the closing of the ring take place almost simultaneously. The preferred solvent is methyl ethyl ketone. In examples (1) 15-Iodo-pentadecanoic acid is added to a suspension of potassium carbonate in boiling methyl ethyl ketone to give pentadecanolide. (2) 15-Bromo-pentadecanoic acid is added to a boiling suspension of potassium carbonate in methyl ethyl ketone to give pentadecanolide. (3) From 11-Iodo-undecanoic acid there is obtained in the same way as in example (2) undecaactone. (4) As in example (3) using a different heating period. (5) 16-Iodo-hexadecanoic-12-acid-1 is treated as in example (1) to give 1-oxo-hexadecanolide.
