Filed: 1958-10-16
Abstract: 871,656. Radar. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. July 2, 1959 [Oct. 16, 1958], No. 33094/58. Class 40(7) Relates to airborne speed and/or distance measuring radar utilizing the Doppler effect on earth reflections. According to the invention transmissions are made at a number of different angles of depression relative to the plane containing the pitch and roll axes of the aircraft and the strengths of derived signals each dependent on the magnitude of the echo signal corresponding to a differently-directed transmission are compared to derive information for calibrating or correcting the measurements. The echo spectrum is distorted by the increase of echo power with depression angle and it is stated that known measuring devices may give an incorrect velocity indication. Aerials 21, 31 are switched to receiver 5 synchronously with transmitter 1 output to aerials 2, 3. The receiver output, which is at frequencies corresponding to the beat frequencies between transmitted and received signals, is fed via filter R, K amplifier 8, rectifier 9 and synchronous switch 411 to amplitude comparator 10, 11 whose output controls motor 16 to adjust the filter characteristic so as to yield a correct velocity measurement by known device 7. The comparator is arranged to adjust the filter until the comparator inputs are in a predetermined relationship which may be equality. More than two differentlydirected beams may be used, and simultaneous transmission effected. The invention may be applied to Doppler-effect systems in which a number of beams of different directions relative to the aircraft heading are used for speed and drift measurements. Manual control of the filter may be employed.

Title: Improvements in and relating to an apparatus for producing a master, such as a stencil or an offset plate by electrical perforations
IPC: B41C1/14
Filed: 1964-08-17
Abstract: 1,034,246. Copying by scanning. ZEUTHEN & AAGAARD A/S. Aug. 17, 1964 [Sept. 7, 1963], No. 33565/64. Heading H4F. The invention relates to an apparatus, Fig. 1, in which an original picture 3 mounted on a drum 2 subjected to rotational and axial displacement is viewed by an optical system including a lamp 5 and photo-electric cell 18 (arranged as shown more fully in Fig. 2) to produce an electric signal which is applied to a circuit 12 to control the application of a potential to an electrode 13 whereby a printing blank 4 is perforated, the arrangement being such that circuit 12 is triggered only when the signal exceeds a predetermined value. In accordance with the invention the grey-value of the original picture which results in a signal of the predetermined value is controlled by means of an adjustable dimming member 14 included within the optical system. In one arrangement the member takes the form of a disc constructed as shown in Fig. 3 and adjustable angularly by control 17. The member may be produced photographically or by printing on a translucent plate. An alternative construction, Fig. 4, arranged for translatory motion consists of a perforated opaque plate. Reference is also made to an arrangement in which the transparency varies with the angle of incident light and an arrangement based on angularly adjustable slots. The use of a plurality of light transmitting areas in the light path, as shown in Figs. 3 and 4, allows for irregularity in the distribution of light flux. The variation of light transmission in terms of adjustment of control 17 is chosen to be logarithmic. A further dimming member 20 having a predetermined number, e.g. four, of different transparency values may be provided in the apparatus to permit half-tone reproduction in a manner similar to that described in Specification 954,752. The member is rotated by a motor 22 which is pulsed once for each line 5 carried on original 3 by means of electromagnet 24, 27 which coacts with a ferromagnetic bar 23 carried by drum 2. By this means the four transparency values are introduced in turn, a different one for each line, and cause different grey levels to result in the predetermined signal valve which triggers circuit 12. Reference is made to an arrangement which changes the transparency for every second or third line, and to the use of irregular or random changes. An electric commutator system 29, 30 may be provided for controlling circuit 12 to change the trigger level.

Abstract: 785,165. Structural fatigue indicators. LUNDBERG, B. K. O. Nov. 28, 1955 [Nov. 30 1954], No. 34061/55. Class 106 (2). An apparatus secured to a structure for indicating the fatigue therein comprises members actuated by the elongation of a structural element and so devised as to integrate the effect of elongation changes of varying magnitudes. The elongations are transmitted by a rod 22 to the indicating device 12 bolted to the structure 10 and by means of a peg 28 cause rotation of a pulley 26 driving by means of a belt 34 a smaller pulley 30 secured to a larger pulley 36. A spring-loaded belt 42 driven by the pulley 36 passes round an oval-shaped pulley 38 pivoted at 46 so that the greater the elongation transmitted by the rod 22, the greater the rotation of pulleys 26, 30, 36 and also the rotational movement of the pulley 38 about its pivot 46, thereby decreasing the length of contact of the belt 42 with the pulley 38 and increasing the drive ratio between pulleys 36, 38. An arm 48 pivoted at one end to the pulley 38 therefore moves a greater distance for a large elongation of the structure than it does for a small elongation. The other end 50 of the arm 48 engages a ratchet 54 secured to a pulley 56 driving by means of a belt 58 a further pulley which drives through a changedown gear-box 64 an indicator dial 66 readable against a fixed annular scale 72 which may have indicia 70a, 70b indicating the permissible fatigue limits of the structure to which the indicator is attached. In another embodiment means are provided for summation of both. positive and negative elongations.
