Title: Ion source using a high frequency field
IPC: H01J27/18
Filed: 1957-09-24
Abstract: 849,565. Ion sources. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 24, 1957 [Oct. 3, 1956], No. 29925/57. Class 39(1). [Also in Group XL(c)] An ion source in which gas introduced through a tube 2, Fig. 1, is ionized in the space 6 to form a plasma by means of a high frequency field set up on coaxial line 2, 7, and in which there is set up an axial magnetic field, has an insulating member 5<SP>1</SP> projecting into the plasma to form a concave surface 14 from which ions extracted through the electrode 3 are focused to a crossover in the exit aperture 4. Ionization is through the phenomenon of electron gyroresonance obtained when the magnetic field B and the wave-length K of the applied high frequency are so related that the product BK lies between 5000n and 7500n gauss-cm. where n = 1 or 2. In another embodiment, Fig. 3, the ionization space is constituted by a metallic cavity 25 which can be tuned by deforming the wall portion 18. The mechanism includes a cup part 22 and a lever arm 20 which is pivoted at 28 and is adjusted by screwing the nut 26 on to the sleeve 21. The envelope cover 16 is screwed at 17 on to the wall 18. The walls of the cavity may be covered with sheets of a substance having a low coefficient of recombination for the ions, e.g. zirconium oxide. The magnet system may consist of a pair of coils producing fields in aiding or opposing relationship or a cylindrical, annular or toroidal permanent magnet. Annuli of soft iron may be used to modify the shape of the field. The high frequency energy may be coupled into the apparatus through a coaxial line in which the outer conductor 32, Figs. 9, 10 terminates in a ring 33 which is joined to the inner conductor by radial spokes 34. In another modification, Figs. 11, 12, the inner conductor terminates in a spiral 35 along which a travelling wave propogates, is reflected at the free end and then completely absorbed. The spiral is dished as shown, to permit better focusing of the ion beam.

Title: Improvements in or relating to a method of, and apparatus for use in measuring any displacement and/or rotation of an object parallel to a fixed plane and relative to a reference position
IPC: G01D5/26
Filed: 1970-06-19
Abstract: 1276593 Optical position detector OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES 19 June 1970 [20 June 1969] 30013/70 Heading H4D To determine displacement and/or rotation of an object 1, Fig. 1, in a fixed plane, the object 1 is provided with a pattern 2 of sharply defined areas of light and dark (diagonally opposed dark and light squares, Fig. 2, or a dark cross, Fig. 3) symmetrically arranged round a central point C1. The image of the pattern is projected on to the target of a photo-electric transducer tube 4 to produce an electron stream having a crosssection corresponding to the pattern. The electron stream falls on to a screen having an aperture through which electrons pass with an intensity proportional to the brightness of the corresponding point in the pattern. A magnetic field deflects the electron stream round a closede.g. square pathso that the aperture can be considered to scan/describe a corresponding (square) path through the stream whereby the passed electron intensity and a corresponding electrical output signal undegoes sharp transitions corresponding to the boundaries between the light and dark areas of the pattern. The object and pattern are placed in a reference position (C 1  at point C 0  and the boundary axes Y 1 , X 1  coincident with the path axes Y 0 , X 0  and the times t 1 , t 3 , t 5 , t 7 , Fig. 5, of the transitions in the output signal (with reference to time to when C 0  is at corner P 0 ) taken as references. Corresponding times/or the pattern position (x, y, A 1 ) as shown are t 1 <SP>1</SP>, t 3 <SP>1</SP>, t 5 <SP>1</SP>, t 7 <SP>1</SP> and where T = period of each scan, 2L = length of square. Integrating circuitry operating on the output signal (5d) and reference signal (5c) produce signals proportional to (1 + a), (1 + b), (1 + c), (1 + d) and x, y, A 1  can then be determined using standard analogue computations. A missile 71, Fig. 7 in a wind tunnel, can have three patterns 73, 74, 75 ascribed on it, such that, using detectors 82, 84, 86, the three dimensional position and attitude of the missile can be determined.

Abstract: 1281002 Very high pressure apparatus E I DU PONT DE NEMOURS & CO 30 June 1969 [28 June 1968] 31117/68 Heading B1X [Also in Division Cl] Bodies such as discs and plates or rods and tubes which have a minimum dimension and lateral boundaries which are perpendicular thereto are subjected to shock by applying to said boundaries a pressure pulse which, in the steady state, is of substantially uniform magnitude and duration over the lateral boundaries and of constant velocity in the direction of propagation; the magnitude being sufficient to ensure that the velocity of the shock wave is at least equal to the velocity of the pressure pulse; and the duration being sufficient to sustain a uniform shock wave over at least 50% of the area between the lateral boundaries. As shown in Fig. 1, a cylindrical body 1 of a material such as carbon, hexagonal boron nitride or silicon nitride is contained in a cylinder 2 which is inserted into another hollow metal cylinder 5 surrounded by explosive 9. The latter is detonated with circular symmetry by means of blasting cap 11 and explosive disc 10 so that the hollow metal cylinder collapses progressively onto the cylinder 2 and solid 1 which may thereby be converted to diamond, cubic or wurtzitic boron nitride or a crystalline silicon carbide. 7 and 8 are spacing discs. If desired, a massive rod may be included along the axis of the cylinder. In Examples 1-4, detailed description is given of the end closures and type and disposition of the explosive in an apparatus generally similar to that shown in Fig. 1. Example 7 describes an apparatus using explosive wrapped directly round the containing cylinder, there being no driver cylinder. Where flat bodies are treated in accordance with the invention they may be supported by a massive backing plate and the shock applied progressively by means of a driver plate supporting a layer of explosive. Point or line initiation of the explosive may be employed. Driver elements may alternatively be driven by a compressed gas gun or a gun charged with a deflagrating explosive.
