[Also in Group XL (b)] A directional aerial system capable of producing a desired complex radiation pattern (e.g. cosec<SP>2</SP>) comprises a plurality of directional aerial elements, linearly arranged so that their individual radiation patterns combine, and a branched feeder feeding each element by means of a separate branch and provided with means at each branching point to adjust the power distribution and adjustable phase shifters between the branching points to adjust the phase relationships between the energization of the various elements. A set of five horns 1, 2, 3, 4 and 5, may be used as the aerial elements fed by individual branch guides 11, 12, 13, 14 and 15 from a main feeder 16. At each branching point 17 a ribbed spring bronze membrane 19 joined at its edges to the narrower walls of the feed waveguide 16 and at one end to the point where the waveguide walls divide is provided. This membrane is flexed to adjust the relative amounts of energy passing into the branch and down the main guide by screws 20, 21 and low loss rods 22, 23. Compensation for the disturbance caused by rods 22, 23 may be provided. The phase shifters 18 comprise a pair of tapered plates almost as wide as the narrow sides of the main feeder and parallel thereto which are adjustable towards and away from each other by screws and low-loss rods. In another embodiment, no branch guides are used and the radiating horns 3 are branched directly out of the main feeder through a slot 29 whose effective length is varied by one or a pair of screws 31. A dielectric disc 30 is fitted in the horn. The aerial system may be used to illuminate a parabolic reflector.

IPC: G01R15/14
Filed: 1963-04-25
Abstract: 1,080,014. Insulation testing. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 2, 1964 [April 25, 1963], No.16322/63. Heading G1U. A bridge circuit for detecting high voltage discharge in electrical insulation has one pair of adjacent arms formed by a pair of tunable inductances arranged with their axes at right angles to each other, the other pair of arms formed by a discharge free capacitor 1 and a capacitor 8 incorporating the test specimen as its dielectric, a search coil having an axis movable relative to the axes of the inductances and means 13 for indica ting the signal induced in the search coil. The capacitors are connected by screened cables 9, 11. Each inductance has a primary coil 4, 7 with the earthed end connected to the mid point of the main inductance coil 2, 5 which is shunted by a tuning capacitor 3, 6. The search coil may also be tuned for maximum sensitivity. A low alternating voltage is applied between terminal 14 and earth, and each inductance is tuned so that when the search coil is aligned with it a maximum signal is picked up. The detector is rotated to the position of minimum pick-up; if the minimum pick-up is not zero, because the capacitors 1 and 8 have different loss angles, it is made zero by slightly detuning one of the inductances. The bridge is now insensitive to supply noise. Any discharge in the specimen when a higher voltage is applied to the bridge will now be indicated by an output from the detector, which may be calibrated by coupling a reference voltage source 19 through capacitors 17, 18 to additional windings on the inductances arranged to produce a resultant signal in the detector.

Title: Manufacturing method for a delay line structure
IPC: H01J23/24
Filed: 1960-05-10
Abstract: 881,118. Making waveguides. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 10, 1960 [May 27, 1959], No. 16440/60. Class 83 (2). A method of making a vane-type delay line or a comb-type interdigital delay line (Fig. 1) comprises the steps of stacking alternate thin copper plates 1 and spacers 2 of iron, steel or duralumin. The plates and spacers are angularly aligned along one side 5 and then compressed axially. In the case of a delay line which has fingers apertured by a longitudinal channel 6, this channel may be used to accommodate a clamping rod 7. A copper base 11 is then deposited electrolytically along the side 5 and the spacers 2 are dissolved in an acid bath which does not attack the copper. Washers 10 may be inserted between the plates, during the original assembly operation, to maintain the shape of the assembly during the elimination of the spacers, and these washers will drop out when the rod 7 is removed. The line is then submerged in liquid " Plexiglass " (Registered Trade Mark), which is polymerized to form a solid block, the lateral surfaces are machined true and the block sawn into vane or finger-type combs. Finally, the " Plexiglass " is dissolved away and any burrs removed by acid. Dimensions are given of a typical delay line produced by this method. A cylindrical structure may be obtained by rotating the stack slowly in the electroplating bath.

Title: Traversing mechanism for machine tools
IPC: B23Q5/34
Filed: 1957-05-24
Abstract: 834,838. Drilling-machines: HERBERT, W. B. May 24, 1957 [May 28, 1956], No. 16520/57. Class 83 (3). [Also in Group XXXVII] A machine-tool comprises an abutment 40, Fig. 2, engaging a feed-screw 27 while the screw is rotated to position a slide 3, and means for disengaging the abutment when the slide is positioned, to prevent creep. In a jig-boring machine, push-button and manual controls 11-14, Fig. 1, are provided for the table 3, slide 4 and drill-head 9, and manual clamps 16, 17, and gauging-stops 20, 21, for the table and slide. The traversing mechanism 2 may be applied to the table 3 (as shown), the slide 4, or the drill-head, and is enclosed in a housing 25 mounted on the slide 4, so that the screw 27 traversing the table 3 enters a bush 26. A sheave 29 on the screw carries a stub-shaft 33 from which project arms 34 bearing pairs of rollers 35, 36. The arms are restricted to movement axially of the sheave by a slot 37. The rollers 35 engage a surface on the sheave, and the rollers 36 engage a pair of helical cam surfaces on the rotatable abutment 40. The feed-screw 27 is rotated by a motor 45 to position the table 3 approximately, and the screw and the table together are then pushed bodily to their final position by rotating the abutment 40, by a motor 48 and gearing 50, 52. In operation, a measuring rod 22 is positioned on the table 3 to determine the final position of the table, and a button is pressed to start the motor 45. The table is traversed by the screw until the rod 22 abuts a plunger 86. Fig. 11, to swing a lever 92 and release a micro-switch 62 to stop the motor 45. Release of the switch 62 also starts the motor 48, and the abutment 40 is rotated to push the slide slowly to its final position. The lever 92 has a forked end in which is pivoted a second lever 89. The lever 89 releases a second micro-switch 63 when the plunger 86 has swung the lever 92 a further distance, to cause the heel of the lever 89 to be tilted by an adjustable stop 97. The table is then in its correct position and the switch 63 causes reversal of the motor 48. The cams 41, 42 are thus withdrawn from the rollers 36, and the screw 27 is unstressed. The motor 48 is finally stopped by a switch 74 operated by a dog on the abutment 40. In a modification, the screw 122, Fig. 16, is connected to a bush 128 having flanges 126, 127 and carrying a screwed-sleeve 129 prevented from rotation by a sliding pin 131. When the table has been adjusted by the screw 122, a worm-wheel 133 engaging the sleeve 129 is rotated to push the table to its final position. The worm-wheel is then counter-rotated. The screw 122 and the worm-wheel 133 are rotated in the opposite directions when it is desired to move the table to the left.
