Title: Improvements in or relating to beam capture control devices
IPC: G01S11/06
Filed: 1964-03-06
Abstract: 1,043,773. Radio navigation. BENDIX CORPORATION. March 6, 1964 [March 8, 1963], No. 9621/64. Heading H4D. In an aircraft approach along a localizer or V.O.R. beacon course it is stated to be desirable to know the distance to the transmitter. According to the invention this is achieved without the use of radar by producing a voltage proportional to angular deviation from course (" beam error "), measuring the change in beam error voltage over a predetermined time interval beginning when the aircraft reaches a predetermined beam error, and comparing the measured voltage change with that which would occur at a known distance from the beacon along a parallel flight path. In the embodiment, Fig. 2, receiver 11 provides an output A.C. voltage proportional to beam error and this is fed to a distance computer associated with an automatic pilot via the load winding 17 of a saturable reactor 12 the control winding of which is fed with a D.C. voltage from a rectifier 14 via a contact 22 which is closed a predetermined time after the energization of the coil 36 of time-delay relay 15, coil 36 being energized via a switch 19 which closes when beam error reaches, e.g. three degrees. The A.C. voltage fed to rectifier 14 is derived from a " synchronizer " 13 and is a constant fraction KE of the beam error signal E. After the delay introduced by relay 15 the D.C. voltage is applied to control winding 16 thereby reducing the impedance of load winding 17 and the proportion of beam error signal appearing across transformer 21 increases; at that instant contact 34 removes A.C. from motor 27, synchrogenerator 25 stops and the voltage across resistance 29 solely depends on distance x from the beacon. Rate generator 26 provides for negative feedback in known manner. The computing process is described with reference to Fig. 3 and involves calculating x=20 sin (3 - #<SP>1</SP>)/sin (3 - #) where #<SP>1</SP> is known beam error after the time delay at known distance 20 miles and # is measured beam error at distance x; the computer may comprise a Wheatstone bridge.

Title: Improvements in rangefinders for photographic purposes
IPC: G03B13/14
Filed: 1933-04-03
Abstract: 400,518. Range and view finders for cameras. ZEISS, C., [Firm of], Carl-Zeiss- Strasse, Jena, Germany. April 3, 1933, No. 9926. Convention date, April 6, 1932. [Classes 97 (i) and 98 (i).] In a rangefinder for photographic purposes comprising two telescope systems with their objectives at the ends of the rangefinder base, the focal length of the objectives is not greater than that of the oculars, so that the field of view of the instrument can be made to correspond to that presented to the camera objective, and the instrument can thus be used also as a viewfinder. In Fig. 1 each objective consists of a converging lens 4 in rear of a member 1 comprising a quarter of a sphere having two plane semicircular surfaces at rightangles to each other, and a spherical surface. The line of intersection of the two semicircular surfaces is disposed at 45‹ to the base so that these surfaces act as a roof edge reflector. The focal planes of the objectives are immediately in rear of the lenses 4, and in one, or each, of these planes there is provided a diaphragm 14, the aperture of which is such that the field observed in the rangefinder is equal to that of the image produced by the camera objective. The oculars consist of converging lenses 6, 7 and a prism system consisting of three reflecting prisms 8, 9, 10 for the left-hand objective and three reflecting prisms 11, 12, 13 for the righthand objective. These prisms are arranged alternately, as in Fig. 2, with their lightexit faces in the same plane, so that the images can be made to cover each other by rotating one of the objectives about a vertical axis 3. The range of the object may be indicated by a pointer carried by the pivoted objective. In another form, Figs. 3 and 4, each objective consists of a lens 21, and the light is deflected along the base by roof-edged prisms 23. The oculars and their prism system consist of two glass bodies 28, 29 bounded by parts 30, 31 of a common spherical surface, and by reflecting surfaces 32, 33 and 34, 35. The part 40 of the body 28 overlies the part 41 of the body 29 so that a horizontal division line appears in front of the viewing aperture 17. The focal length of the oculars is equal to that of the objectives so that each telescope has unit magnification.

Title: Improved method of and means for compressing newly formed pipes or like hollow articles of concrete
IPC: B28B21/92
Filed: 1944-05-23
Abstract: 590,600. Moulding concrete pipes &c. ROCLA, Ltd., and FITZPATRICK, F. L. May 23, 1944, No. 9960. [Class 87 (ii)] [Also in Group XXIX] To improve the properties or to pre-stress the reinforcement of a concrete pipe P, pressure is applied to the inner surface of the pipe, when newly formed, by expanding a deformable, non- circular, hollow, sheet-metal core 1, which is inserted in the pipe, while it is still in a mould M, with a layer of sand S packed between the core and the pipe. The core is filled with fluid before or after insertion in the pipe, and is expanded by heating the fluid or applying pressure thereto. In the apparatus shown the fluid, e.g., water, is heated by passing steam through a U-tube 5. Sand restraint rings may be fitted over protuberances 6 on the uppermost circular end portion of the core and the sand may be slightly damped at the top to prevent the sand being squeezed out. Solid or hollow fillers may be used in the sand, when a small core section is used. The pipe may be moulded by a rotary process, the thickness of the pipe being determined by rings 9 which may be slit radially to offset the tendency for the ends of the pipe to receive less effective pressure. A richer mix may also be used at the ends of the pipe to correct this tendency. With a reinforced pipe, after the application of an initial pressure, the bolts 16, fastening the moulds may be slightly relaxed or resilient washers may be used with the bolts, and the pressure is then increased and may be maintained until the concrete is hard. This relaxing of the mould fastenings puts more tension on the reinforcement. To prevent cracking of the outer surface of the pipe it may be lightly vibrated. When the pressure is applied to the fluid by means other than heating, hot sand may be used or heat may be applied by passing a hot fluid around the pipe, to reduce the setting time. The core may be longitudinally corrugated and may be of triangular, rectangular, or other polygonal section or it may be in two or more complementary parts with sand between the parts. The expansion given to the core is not sufficient to cause a permanent set in the metal. A connecting rod may be passed through the core to tie its ends together. Specification 433,059 is referred to.

Patent HK-112997-A (HK)
Title: An optical amplifier
Inventor: CASSIDY STEPHEN ANTHONY
IPC: G02B6/34
Filed: 1997-06-26
Abstract: An optical amplifier comprises an erbium-doped, silica-based optical fibre (6) coupled to a second optical waveguide, comprising a fibre (4) having a D-shaped cross-section. The second optical waveguide (4) has an overlaid grating (10) formed on a silica wafer (9) which is constructed and configured so that the waveguide filter provides loss in transmission substantially at the wavelength of the gain peak of the amplifier. The resonant reflection wavelength is chosen to be substantially equal to, or greater than, the wavelength of the gain peak of the amplified gain spectrum. Transmission losses at wavelengths shorter than the resonant reflection wavelength of the grating act to reduce the gain peak thereby flattening the gain spectrum of the amplifier so providing a larger useful gain bandwidth for optical fibre systems having a cascade of such fibre amplifiers.
