Title: Method of reducing noise in optical position finding apparatus
IPC: F41G7/30
Filed: 1965-01-28
Abstract: 1504276 Optical missile tracking ELTRO GmbH 28 Jan 1965 [26 March 1964] 3721/65 Heading H4D [Also in Divisions G2-G3] In an optical object-locating system in which radiation from the object is passed to a receiver via a variable-speed rotating modulating disc, the receiver output is supplied to a heterodyne circuit which employs both the disc rotational frequency and the output of a local oscillator to derive the heterodyne frequency, thereby compensating for the variations in disc speed. The system is used to control a missile carrying an infra-red emitter. Position-representing data derived by the locating system is supplied, over a wire, to the missile to adjust control surfaces and to correct deviations of the missile from the target direction. As the missile spins about its longitudinal axis during flight, control signals must be applied to the control surface at a particular instantaneous rotational position of the missile, to effect the correct lateral adjustment of the flight path. This is achieved by synchronizing the rotation of the modulating disc with the rotation of the missile, so that the data signals derived are correctly phased.

Title: Improvements in or relating to means for tensioning or stretching artificial filaments or threads during or after production
IPC: D01D10/04
Filed: 1940-02-29
Abstract: 539,200. Apparatus for collecting or stretching artificial filaments. ASHCROFT, D. G., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 29, 1940, No. 3781. [Class 2 (ii)] [Also in Group IX] A device for tensioning, stretching or holding artificial filaments while permitting shrinkage comprises a rotatable frame having a number of screw-threaded rollers mounted upon it and forming a cage around which a filament can be wound so that it is supported, with threading of the rollers, substantially in the form of a helix, the rollers being so constrained that, while the frame is turning, each roller has a turning movement, relative to the frame, on its own axis and the helix is caused to travel in the direction of its axis. The turning movement of each roller is the same in direction and extent as that of the other rollers. As shown, cylindrical rollers 3 are mounted with their axes parallel to the axis of rotation of the frame 1 which is fixed to the axle 2, driven by a pulley 6, the rollers carrying gears 7 geared to a wheel 8 fixed to the bearing 5 and of the same size as the gears 7 so that, as the frame makes one rotation, the rollers rotate about their axes once in the opposite direction and shoulders 11, at the commencement of the threading of the rollers, remain at the top of each roller and assist the feeding of the filament into the device ; after the frame has completed a rotation the filament has been fed axially along the roller for one pitch of the screw thread and eventually leaves the roller at its outer end and is led away for processing. In a modification, the rollers are geared to the wheel 8 through sprocket gearing so that they rotate twice for each rotation of the wheel and in the same direction. The rollers may be arranged with their axes in radial planes at an angle to the axle 2, so that the filaments are stretched, or allowed to shrink, according to the direction of rotation of the frame. In another form, the rollers are partly cylindrical and partly conical so that, if the rollers are arranged to rotate in the same direction as the frame or in the opposite direction at a speed less than one rotation for each rotation of the frame, the filaments will be stretched as they move from the boundary of the cylindrical part and conical part to the largest diameter of the conical part ; if the rollers rotate in a direction opposite to that of the frame and at a speed greater than one rotation for each rotation of the frame, the filaments will be permitted to shrink, or the effects may be reversed by rotating the frame in the opposite direction and feeding the filaments to the largest diameter of the conical part of the rollers. The rollers may be supported at both ends in a rotating frame, a travelling band being provided at one end of the rollers for assisting the winding of the filaments on the rollers, the filaments being driven through a guide and twisted about the band.

Title: Improvements relating to radio lenses
IPC: H01Q15/04
Filed: 1963-01-30
Abstract: 1,025,182. Aerials. R. L. TANNER. Jan. 30, 1963 [Feb. 23, 1962 (2)], No. 3785/63, Heading H4A. A radio lens comprises a single pair of overlying spaced surfaces at least one being a wire mesh, the mesh size being smaller than the shortest operating wavelength. The lens is stated to be effective over a wide frequency band (e.g. 1 to 1000 Mc/s.) and to afford low side-lobe levels. The mesh may be square, triangular or hexagonal and each wire may have two or more strands. In one embodiment, Figs. 1, 2, portion 24 is the lens, producing azimuthal beam shaping and a peripheral portion 25 forms a horn radiating structure for elevational beam shaping and for matching the lens impedance to that of free space. Mesh 30 is secured to an aluminium ring 31 supported by non-conductive poles 32; the inner edge of the upper horn wire mesh is joined to ring 31 and the outer edge thereof is supported by non-conductive poles 23. The mesh of the horn may be of different form to that of the lens, Fig. 5, or the horn may be of conductive sheet. Meshes 30, 34 are substantially identical to one another and are oriented with respect to one another such that corresponding sides of opposite wire meshes lie in a plane normal to both meshes, at least in those lens portions in which the separation between the meshes is not greater than mesh size. It is stated that when the separation s between the meshes is less than one-tenth the mesh size the velocity of propagation V is 1/#2 that of light V c ; and when s is not less than four times the mesh size, V=V c . To afford a narrow azimuthal beam, the diameter of lens 24 is made several times larger than the longest operating wavelength, e.g. if three times, the half-power beam width at that wavelength is some 20 degrees. A desired frequency range may be 4 to 30 Mc/s. and dimensions therefor are given. Another embodiment is a Luneburg lens, Fig. 3, for converting a peripheral point source 37 into a cophasal wave front 38; design details are given. In a further embodiment one mesh structure is planar, Figs. 4, 5. The qualitative manner in which the lens operates is discussed, Figs. 6, 7. In another embodiment, Fig. 9, capacitors 93 are added across the meshes; or the meshes may be loaded inductively 103, Fig. 10. Wave velocity is thereby reduced. In another method of reducing wave velocity a zig-zag portion is included in the side of a mesh, Fig. 11. A feed horn may be mounted for rotation along the peripheral portion of the structure; or fixed feed horns facing different desired azimuthal directions may be employed. To reduce the variation of distances of separation between the opposite meshes which would otherwise be undesirably large, each conductor of a mesh is made of two strands 132, 133 and 134, 135, Fig. 12. Further details are described with reference to Figs. 14 to 18. Each conductor may have three strands, Figs. 19a, 19b or more than three strands, Figs. 20 to 22.
