Title: Improvements in or relating to wireless aerials
IPC: H01Q1/18
Filed: 1944-11-17
Abstract: 587,912. Aerials. SCAIFE, F. N., HOYLE, F., EHRENSTEIN, F., and WRIGHT, C. S. Nov. 17, 1944, No. 22917. [Class 40 (v)] [Also in Group XXIX] A wireless aerial array comprises two or more aerials connected to separate feeders and has connected in at least one of the leeders a phase-shifting device witich is automatically controlled by any angular variations in the elevation of the aerial array thus varying the amount of phase-shift in proportion to the displacement of the aerial array so that the beam retains its predetermined elevation. Fig.1 shows an aerial which comprises a cheese aerial split in the horizontal plane by a horizontal wall and fed by two wave guide flares 3 and 4. The flares are emergized from a source 8 through a wave guide 7 which divides into two Wave guides 5 and 6 at a branch point 9. A phase-shifting device 12 comprising a sliding section is connected into the wave guide 6, the movement of the sliding section being controlled by a gyroscopic and mechanical amplifying device 13 (see Group XXIX).. If the elevation of the aerial changes (due, for example, to pitching or rolling of a vessel on which it is mounted), the gyroscope axis remains vertical and communicates its relative movement to the section 12 by mechanical coupling, thus creating a phase-shift in the lower half of the array and altering the direction of the beam so that it remains horizontal. The device 13, Fig. 2 (not shown), comprises a gyroscope and an oilamplifying valve which couples the gyroscope to the phase-shifting device 12. Alternatively, an all-electric control system may be used. In a further embodiment, Fig. 3 (not shown), the device 13 incorporates additional control means so that the beam may be stabilised at any desired elevation. Alternative forms of phaseshifting device 12, e.g. a mass of dielectric moving in a wave guide may be used. Moreover, the invention may employ more than two aerials and a plurality of co-operating phaseshifting devices.

Filed: 1939-08-09
Abstract: 534,144. Valve generating circuits. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Aug. 9, 1939, No. 22984. Convention date, Sept. 2, 1938. [Classes 39 (i) and 40 (v)] An electron beam oscillator, of the type described in Specification 523,712 in which bunching of the electrons is produced and the frequency is a function of the time of flight of the electrons, has its frequency stabilized by deriving a voltage corresponding to changes in external parameters which is applied to controlling the time of flight of the electrons or the current in the beam so as to maintain the frequency constant. The Figure shows enclosed resonators 1, 2 coupled by loops 13, 14 and line 15 and having an electron emitter 4, coupling members 20, 201, detector grids 21, 22 and detector plates 23, 24. The beam current is controlled by grid 16 and by tube 18 by variations in supply voltage or by internal variations in electron velocity. The current from plate 24 is a function of the flight time of electrons between members 1 and 2 and produces voltage across resistance 26 which is amplified by valve 27 and applied to tube 18 to compensate for variations in flight time. Variations in supply voltage may be used to control the voltage of tube 18 and produce compensation by valve 31. A resistance 36 connected to both plates 23, 24 has a voltage proportional to the total electron emission from the emitter 4 which may be amplified by valve 37 and applied to a control grid 16 to compensate the change in the beam current. Alternatively an internal sampling electrode 17 may produce voltage in resistance 41 which is amplified by the valve 42 for the same purpose. Supply variations may be compensated by the grid 16 through amplifying valve 44. Specifications 517,264, 530,785 and 548,725 also are referred to. The Specification, as open to inspection under Sect. 91 also describes a single resonant member with a reflector arranged to reflect the beam into the member. This subject-matter does not appear in the Specification as accepted but forms the subject-matter of Specification 535,767.

Abstract: 406,310. Circular looms. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and HOWARTH, W., c/o British Celanese, Ltd., Spondon, near Derby. Aug. 18, 1932, No. 23168. [Class 142 (ii).] Shedding mechanism for a circular loom comprises a plurality of banks of fine shedding needles adapted to control the warp threads, each bank having closely spaced slots adapted to permit sliding movement of the needles and to support the needles over a substantial portion of their length, and means to engage selected needles and to effect the shedding movements of the needles by drawing them under tension. In the loom shown eight banks are provided, each comprising a ring 14 having on its upper side slots 16 in which rest needles 17. The rings are held in place by pins 33, Fig. 2, projecting from their undersides and engaged by extensions 34 on the rings below. The lowermost ring is bolted to a pillar 15 which rotates at warp speed. As the banks rotate, stationary cams 24, arranged opposite each shuttle 11, engage between projections 19, 23, Fig. 3, on the needles, and the heald 22, which is secured to eyes 21 on the needles, is pulled outward against the tension of springs 26 secured to a member 29 also rotating at warp speed. The springs may be dispensed with, the inward movement of the needles being effected by the tension in the warp threads. According to the Provisional Specification, one spring may be provided for several healds. Projections 20 on the underside of the rings limit the movement of the needles. The lift of the cams may be such as to open the shed to the full width of the shuttle, or may be just sufficient to commence a shed which is widened by the entrance of the shuttle thereinto. In the latter case the eyes 21 may be lengthened to permit the spreading of the warp threads. For the weaving of 5-shaft satin the warp threads are divided among five rings 14 as shown in Fig. 7. The first of five warp threads is connected to one ring, the fourth thread to the next ascending ring, and the second, fifth and third threads to the third, fourth and fifth threads respectively. At one shuttle point all the " first " threads are pulled outwards, at the next all the " fourth," at the next all the " second," and so on. At any particular shuttle the same set of warp threads is operated on at each revolution of the loom, so that the number of shuttles must be exactly divisible by the number of rings being used. In the loom shown there are ten shuttles and five rings are being used, and the density of the needles is thirty per inch per ring. Specifications 396,757, 402,822, and 406,028 are referred to.
