Title: Improvements in or relating to methods of and arrangements for correcting axial astigmatism in corpuscular-beam optical systems using an adjustable stigmator
IPC: H01J37/153
Filed: 1966-09-27
Abstract: 1,147,292. Electron lenses. SIEMENS A.G. 27 Sept., 1966 [28 Sept., 1965], No. 43052/66. Heading H1D. In an arrangement for correcting axial astigmatism in lenses in corpulscular beam optical systems having an adjustable stigmator, e.g. in an X-ray microanalyser, a test object G is introduced into the optical path between the plane of the lens O to be corrected and the image side caustic point F1 such that shadow images of edges of the object which lie in a plane perpendicular to the beam axis are formed, as shown in the lower half of the figure, and the stigmator is adjusted until the images are of a form known to be produced when astigmatism is not present. For example the stigmator may be adjusted until the images are symmetrical about an axis perpendicular to the shadow of the particular edge being observed, i.e. about X-X as shown. The edges of the test object are preferably knife edges or are the generatrix lines of a wire. The symmetrical pattern shown is due to the apertural error of the lens. To correct for the axial astigmatism in more than one plane the shadow images of two edges inclined at an angle #, where O  #  90 degrees and preferably # = 45 degrees, are produced and observed successively or in alternating sequence. The stigmator may comprise two coil or electrode systems at an angle #, each system having individual current or voltage controls.

Title: Yarns made from thermoplastic polymers
Inventor: MCINTYRE JAMES ERIC
IPC: D02G3/40
Filed: 1962-11-16
Abstract: A coherent thermoplastic substantially twistless multifilament yarn, made from a hydrophobic synthetic polymer possessing in the form of oriented fibres a water absorbency of less that 1% per weight of fibre at 70 DEG F. and 65% relative humidity, has bonds, between adjacent filaments consisting of this polymer in a crystalline or partly crystalline form, and extending substantially the whole length of the filaments, the degree of cohesion being such that the average cohered filament count-i.e. the number of separate filaments, and bundles of filaments-is 5-80% of the total number of filaments.  The bonds are formed by wetting a multi-filament yarn with a liquid containing a compound which is a solvent for the polymer at an elevated temperature, passing the filaments through a heating zone at a temperature between 140 DEG C. -600 DEG C. to evaporate the liquid, and then cooling the yarn.  The solvent may be applied to undrawn yarn which is then drawn and the yarn cohered during heat setting, or to a drawn yarn before the heat setting stage, or subsequent thereto with a separate heating step being provided.  The yarn may be a polyester or a polymerized olefine-for example polyethylene terephthalate or polypropylene.  The solvent may be tetrachloroethane, chloral g -butyrolactone, anisaldehyde, m-cresol, benzophenone, and 2-phenoxyethanol, benzyl alcohol, acetophenone salicylaldehyde, methyl cyclohexanone, acetophenone, a mixture of nitro-with chlorobenzene, and xylenes.  After weaving or other processing steps the filaments may be separated by scouring, pressing, calendering or treatment with swelling agents or in strong alkaline solutions.  Novel fabric effects may be obtained by a combination of cohered warp and twistless weft yarns or by using a warp with a higher degree of cohesion than in the weft to form a lawn-like fabric, by a combination of two or more yarns of different degrees of cohesion which can be treated so that the yarns with the lesser degree of cohesion are broken down into individual filaments, or by weaving or knitting fabrics from yarns having a random filament bond formed by partial break down of the bonds.  For use as sewing threads the cohered yarns may be coated with a lubricant-for example polydimethyl siloxane.  The yarn filament counter described in Specification 829,330 is used to provide the "cohered filament count".

Abstract: 1,043,777. Automatic position control. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Oct. 27, 1964 [Oct. 29, 1963], No. 43776/64. Heading G3R. The attitude and position of a marine vessel is automatically controlled by the combined outputs of detectors responsive to the heading and position of the vessel relative to perpendicular axes which control a unit applying propulsive thrust along the longitudinal axis of the vessel and a plurality of units applying propulsive thrusts parallel to the athwartship axis. In Fig. 1 (not shown), the inclination of a line 21, attached to a drilling vessel 10, anchored on the sea-bed at 22, and maintained in constant tension by a winch 23, is measured in mutually perpendicular planes parallel to the longitudinal and athwartship axes of the vessel by tiltmeter potentiometers 20. A further compass-controlled potentiometer (not shown) responds to changes in heading of the vessel. Propellers 15, 16, 17, which may be driven by variable speed reversible D.C. electric motors, are speed-controlled automatically from the potentiometers, through servomotor control systems involving differential and integral components, to maintain the vessel in a desired position relative to the wellhead 14. The potentiometer measuring inclination of line 20 in a longitudinal direction controls propeller 15, the potentiometer measuring inclination in a transverse direction controls propellers 16 and 17 in the same senses, and the heading potentiometer controls propellers 16 and 17 in opposite senses. Propellers 16 and 17 may be located in the hull of the vessel as shown or they may be below the bottom. Switches (not shown) may be operated to substitute manual control. Use of hydraulic jets instead of propellers is referred to.

Abstract: 920,008. Superconductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 24, 1959 [Dec. 24, 1958], No. 43831/59. Class 40 (9). Two superconductive gate conductors 24, 26 are connected in parallel to a source 20 of constant current i2 and are self-biased by control coils 25, 27 connected in series with the conductors. The current i2 normally divides equally between the two branches as an increase in the current in one branch tends to drive the corresponding gate conductor more resistive. A signal current i1 in control coils 30, 31 aids the bias from coil 25 and opposes the bias from coil 27 to unbalance the circuit. There is a substantially linear relation between the signal current and the current in each branch. Two or more amplifiers may be connected in cascade. Specification 862,178 is referred to.
