Title: Electron lens
IPC: H01J29/58
Filed: 1954-10-05
Abstract: 773,377. Electron microscopes. RADIO CORPORATION OF AMERICA. Oct. 5, 1954 [Nov. 2, 1953], No. 28710/54. Class 39(1). [Also in Group XL(c)] Cylindrical distortion (astigmatism) in a spherical magnetic lens field produced by a coil between two annular pole pieces in an electron microscope is corrected by a cylindrical electrostatic field produced by a plurality of rod electrodes radially arranged in the same transverse plane, oppositely disposed electrodes being connected together in pairs and the pairs being selectively energized in a manner suitable to correct 'the magnetic field. It is explained that due to the anisotropic nature of the iron of the polepieces and to mechanical maladjustments the magnetic lens is not truly spherical but has a cylindrical component producing astigmatism, and the correcting electrostatic lens must therefore be cylindrical. Six rod electrodes of non-magnetic material pass through insulating bushings 32 of a non- magnetic, e.g. brass spacer 18. The other legs of the L-shaped rods 22 pass through insulating bushings 34 in the upper pole piece 14 to contact members 36. Diametrically opposite electrodes 22 are electrically connected together in pairs, each pair being connected to a separate movable potentiometer arm so that independent adjustment of the voltages of the three pairs is possible, and the three potentiometers are energized from a fourth potentiometer, Fig. 5 (not shown). Preferably, however, the arrangement of Fig. 7 is used, the electrode pairs being connected to three equally spaced taps 52 on a circular potentiometer which has an earthed slider 54 and a diametrically opposite slider 56 connected to energizing potentiometer 46, the sliders rotating in unison 46 determines the strength of the correcting field and 50 its direction. The polepieces and compensating electrodes may have central apertures of the same diameter, Fig. 8 (not shown) or of different diameters, Figs. 9, 10 (not shown) one or both of the polepieces having plates to reduce the lens aperture and to protect the electrodes from electrode bombardment. The polepieces are at earth potential, while rods 68 can be positive or negative with respect thereto to set up a cylindrical convergent lens. If, however, the lower diaphragm is omitted, Fig. 10 (not shown) the electrostatic lens is convergent if the lens electrodes are negative, or divergent if the lens electrodes are positive. In another form, Fig. 11, magnetic shim screws 82 are adjusted to give initial compensation of the magnetic lens field, the rods 84 giving a fine adjustment. In a modification, Fig. 12 (not shown) the magnetic adjusting shim screws have non- magnetic inner ends serving as electrostatic lens electrodes.

Abstract: 715,210. Valve closure members. BRIDGEFIELD, G. P. Dec. 13, 1951 [Dec. 28, 1950], No. 29172/51. Class 135 A rotary conical valve in which the plug 13 is rotatable to permit one or more orifices 14 in the plug to register with an outlet or outlets in the plug barrel 10 has a threaded stem 18 projecting outwardly from the closed narrow end of the plug through a hole in the closed end of the barrel to engage with a nut 23 which is rotatably disposed on the barrel but is restrained against any substantial axial movement relative to the barrel so that rotation of the nut in one direction will tighten the plug to its seating in the barrel whilst rotation of the nut in the other direction will displace the plug axially from its seating. The valve is particularly adapted for connecting pipes of different diameter and as shown comprises a hollow inverted core or plug 13 with diametrically opposite orifices 14 and a barrel 10 with outlets 11, 11'. The barrel has a flange 12 adapted for connection to a flange 31 surrounding an opening in a pipe line of greater diameter than the outlets 11, 11<SP>1</SP>. The valve plug 13 is rotatable by means of a threader stem 18 having an enlarged part 19 and a part 20 in the form of a truncated pyramid at its lower end. The stem 18 is received in a stepped nut or bushing 23 anchored during manufacture to the top of a stuffing box 24. The part 20 is held in a corresponding recess in the top of the plug 13 by a washer 35. Movement of the plug 13 is limited to 90 degrees by a bolt 28 in an arcuate slot 15. The barrel 10 has a ported liner 29. On the application of a wrench to the nut 23, the stem 18 is moved axially and the valve plug moves away from its seating.

Title: Improvements in and relating to processes and plant for the low temperature carbonisation of solid fuels, carbonaceous material and the like
IPC: C10B1/10
Filed: 1922-10-26
Abstract: 192,040. White, W. C. Jan. 18, 1922, [Convention date]. Coking processes; retorts.-In the low temperature carbonization of coal, lignite, peat, shale, wood and similar carbonaceous materials, hot gas is circulated through a rotary retort containing the material until the desired degree of saturation with condensible volatile products is attained with or without intermediate heating during circulation, a part of the gas and distillates being then drawn off for the recovery of byeproducts. Hot gas from a producer 1 is passed through the rotary retort 2 and the resulting gases and vapours passed by a pipe 16 through a tar extractor 4 and forced by a pump 9 along a pipe 8 and through are-heater 10 back to the retort. A portion of the gases may be drawn off by a valve 12 and passed through condensers and scrubbers 5, 6 to a gas-holder 7. The reheater may be supplied with gas either from the holder 7 'or the producer 1. The retort may have internal shelves 18 which serve to shower the material and which may be corrugated or set at an angle to the axis of the retort. By this construction when the feed is interrupted, the circulation of gas is continued and the retort maintained at a temperature suitable for carbonization.

Title: Improvements in and relating to polarimeters and polarimetry
IPC: G01J4/04
Filed: 1961-08-14
Abstract: 945,416. Polarimetry. J. BOR. Aug. 1, 1962 [Aug. 14, 1961], No. 29322/61. Heading G2J. [Also in Division G1] In a method of polarimetry or process control by polarimetric means, the planes of polarisation of two selected portions of a plane polarised beam which passes through a sample under measurement or under process control, and through an analyser, are rotated in opposite senses, and the intensities of the two portions of the beam after passing through the analyser are equalized by adjustment of a polarising component of the apparatus and/or by adjustment of the selected portions of the beam. In the polarimeter shown, collimated monochromatic light from adjustable prism 4 and slit 5 traverses polariser 1 and analyser 2 and falls on one or two photosensitive detectors. In front of analyser 2 is a rotator 3 which, as described in Specification 866, 091, comprises contacting wedge-shaped members for rotating a polarised beam in opposite senses. Between rotator 3 and analyser 2 is a screen 7 having slits 8, 9 equidistant from the median plane of the rotator 3 so as to select two portions of the plane polarised beam, which have been rotated in opposite senses but which, on emergence from analyser 2, are of the same intensity. Insertion of sample 14 into the beam upsets this balance which is then restored by rotation of the polariser 1 or analyser 2 or by transverse movement of screen 7 or rotator 5, the extent of such adjustment being a measure of the rotary power of sample 14 at the wavelength of the monochromatic light. Such adjustments may be carried out manually or, preferably, by a servo system controlled by the photo-sensitive detector(s). Variation of the rotary power of sample 14 with wavelength may be measured by adjusting prism 4 to alter the wavelength passed through the polarimeter. In a modification, Fig. 4 (not shown), the radiation indident on the polarising components is collimated by using a convex and a concave mirror, and a similar mirror system is employed to receive the radiation from the analyser and direct it to the detector. Further, a two slit screen, additional to screen 7, is placed in the incident light beam to prevent scattering; the polariser 1 is a Rochon prism of known kind and the analyser 2 is a modified Rochon-type prism comprising two wedge members with an interface 23, Fig. 5b, the optic axis 27,28 of each wedge being in a plane perpendicular to this interface and being at right angles to each other.
