Abstract: 1518575 Locking pivots MARCONI CO Ltd 27 May 1977 [2 June 1976] 22823/76 Heading E2F [Also in Division H4] An aerial having a whip (9), Fig. 1 (not shown) and ground plane radials 5 is mounted on a mast. The radials 5 are pivotally mounted with rollers 17 at their ends which engage a spring-loaded plate 8 and respective rollers 22 retained by mountings to plate 8. The arrangement is such that when the aerial is pushed into a confined space such as the branches of a tree the radials 5 are pivoted downwardly to the dashed position shown at the right of Fig. 3, and plate 8 is pushed upwards. When the aerial has been pushed through the confined space, plate 8 and hence the radials 5 spring back to their original positions. On retraction of the aerial the radials pivot upwardly, such that the rollers 17 push past respective rollers 22 and radials 5 are therefore not returned to their original position.

Title: Improvements in apparatus for rendering supersonic pictures visible
Inventor: MARTIN HANS-JOACHIM
IPC: G01H3/12
Filed: 1954-08-10
Abstract: 771,930. Ultrasonic inspection devices. VEB C. ZEISS JENA. Aug. 10, 1954, No. 23261/54. Class 118 (2). [Also in Group XL (a)] Ultrasonic pictures are rendered visible by the production of a potential image on the back of a tuned piezo-electric crystal due to the projection on the obverse of an ultrasonic wavefront modulated by the picture content, on to which potential picture a homogeneous electron beam is directed by means of an electron-optic system. The electrons reflected by the potential surface corresponding to the picture content are guided by the same electron-optic system on to a fluorescent screen, on which they produce a visible picture corresponding to the original ultrasonic picture. In the embodiment shown, a discharge vessel 1 is sealed off at one end by a quartz crystal 2 on which is seated a sponge rubber sleeve 3 for coupling to a test piece to be examined. Ultrasonic vibrations are passed through the test piece and thereby modulated with the picture content, e.g., a flaw in the test piece, and impinge on the crystal 2 to cause a potential picture on its inner surface which is provided with a very thin semi-conducting coating. An homogeneous beam of electrons from a gun in the branch 1<SP>1</SP> is deflected by a magnetic field and the electronoptic system 6, 7 on to the crystal 2. Electrons reflected by the potential picture thereon are guided by the system 6, 7 and the same magnetic field on to the fluorescent screen 8 to produce a visible picture. In a modification (Fig. 2, not shown), no magnetic field is required, the electron beam passing through an aperture in a 45 degrees mirror and another in the fluorescent screen before the electron-optic system focuses it on to the crystal. Reflected electrons cause a visible picture on the screen which is viewed by means of the mirror.

Title: Distortion correction in electric wave transmission
IPC: H04B3/04
Filed: 1938-08-10
Abstract: 517,601. Multiplex systems. STANDARD TELEPHONES & CABLES, Ltd. Aug. 10, 1938, No. 23601. Convention date, Aug. 10, 1937. [Class 40 (iv) [Also in Groups XXXVI and XL] In a broad band wired or wireless transmission system involving a number of repeaters, phase-equalizing networks are associated with some or all of the repeaters or are inserted at other points to introduce phase-frequency distortion which is compensated if necessary at the receiving end. By this means intermodulation is minimized. The effects of using phase equalizers having different laws are discussed. The phase equalizers may be adjustable automatically or manually to compensate for changes in phase distortion due to atmospheric conditions, ageing of valves &c. For this purpose two or more pilot currents of different frequencies may be used. Fig. 4 shows a circuit for comparing the phases of two pilot frequencies which are fed to the input circuits CFI, CF2 over crystal filters. The direction of flow of the rectified current in resistances 3, 4 depends on the direction of the relative phase shift of the pilot currents. Other pilot frequencies may be used for automatic volume control. The invention is applicable to ultra short wave wireless transmission involving a chain of repeaters at which the frequency is changed. The inter-modulation introduced by all the repeaters is kept, as far as possible, the same. For this purpose amplifiers having stabilizing feed-back currents N, Fig. 9, have also manually or automatically adjustable resistances 16 common to the input and output circuits. Certain modulation products are balanced out by reversing the input connections of alternate repeaters.

Abstract: 721,572. Automatic voltage-control systems. GENERAL ELECTRIC CO. Sept. 24, 1952 [Sept. 24, 1951], No. 23963/52. Class 38 (4). Variation of ambient temperature influences a temperature-variable resistance in a Wheatstone bridge circuit which is automatically maintained in balance by a motor setting the datum of a constant voltage supply to electric heaters. As shown, infra-red lamps 1 heating a poultry brooder are supplied from a centretapped single-phase A.C. source 11, 12, 13 through an auto-transformer 5. To maintain constant the voltage applied to the lamps, a two-way relay 50, a winding 47 of which is energized by the voltage across the lamps, controls through relays 53, 54 a reversible electric servomotor 45 operating an induction regulator 14 to correct lamp voltage by a bucking or boosting voltage induced into windings 15 and 16 in series with the lamps. A winding 55 of relay 50 is energized when the relay operates in either direction to bias the relay in that direction. Changes of ambient temperature influence a temperature-sensitive resistance 23 to unbalance a Wheatstone bridge network 17, the A.C. output of which is amplified by a pair of double-triode valves 60, 61 to energize a winding 34 of a two-way relay 30 controlling a reversible shaded-pole induction motor 31 operating a potentiometer 26 to rebalance the bridge and operating a rheostat 49 in series with winding 47 to set the voltage at a level corresponding to the ambient temperature. To prevent hunting, relays 53, 54 controlling motor 45 also operate contacts 42, 43 to prevent operation of motor 31 in one sense when motor 45 operates in the opposite sense.
