Title: Improvements in or relating to short wave radio aerials and aerial systems
Inventor: CLOUGH NEWSOME HENRY
IPC: H01Q21/14
Filed: 1950-04-27
Abstract: 721,582. Aerials; radio navigation. MAR. CONI'S WIRELESS TELEGRAPH CO., Ltd. March 2, 1951 [April 27, 1950], No. 10431/50. Class 40 (7). An aerial arrangement for use in a system operating on a wavelength A consists of a pair of mutually perpendicular aerials mounted inside a slotted screening tube, each aerial comprising a pair of bent elements each half of the operating wavelength long and each having end portions at right angles to their centre portion, the elements being arranged so as to be substantially mirror images of each other. In one form the extremities of the two elements are arranged to join physically and electrically to form a loop (Fig. 1) which is a wavelength round. For adjustment purposes the top arm S (Fig. 2) of a rectangular loop may be made movable along the side arms. The aerial feeder F may be arranged as shown in Fig. 1 or as in Fig. 2 for any embodiment. Two rectangular loops at right angles, symmetrical about a centre axis, and inside a screening tube form a system according to the invention which may be connected to a transceiver through a goniometer for beacon or direction-finding purposes, Fig. 3 (not shown). Four loops may be symmetrically arranged round a vertical prism and so energized that the currents in conductors forming a gapped loop round the axis are all in the same direction round the loop. This arrangement (Fig. 4) results in an omnidirectional radiation pattern; Radiation from closely adjacent conductors of adjacent loops tends to cancel out and such conductors may be enclosed in pairs in tubular screens SC. The additional capacity due to the screens involves reducing the physical length of the screened conductors. In another form of multiple loop omnidirectional system, Fig. 6 (not shown), the mid-points of adjacent parallel conductors are coupled by coupling condensers. A crossed-loop directional aerial system may be mounted on the same axis as, and either inside or displaced from, an omnidirectional aerial of the general type described with reference to Fig. 4 to form the aerial arrangement for a direction finder or phase beacon. One form of slotted screening tube in which the aerial arrangements may be mounted is a vertical cylindrical wave-guide T having a ring of vertical slots SL round it. It is preferred to mount a horizontal earth counterpoise CP half a wavelength below the midpoints of the slots. The invention also includes systems using H aerials of the type shown in Fig. 8, wherein the two central portions of the half wavelength bent elements are one conductor. The feed may be across a gap in the conductor as shown, or the conductor may be continuous, or the gap may be bridged by a capacity, Figs. 9 and 10 (not shown). Crossed H aerials may be formed and also omnidirectional aerials by symmetrically arranging a plurality of H aerials round a prism, Figs. 11 and 12 (not shown).

Abstract: 1,205,631. Electrostatic control of cigarette, filter rod and tobacco transport. HAUNI-WERKE KORBER & CO. K.G. 29 Jan., 1968 [8 March, 1967], No. 10659/67. Heading A2C. The travel of tobacco rods, cigarettes or filter rods &c. is controlled or regulated by subjection to the action of electrostatic forces by at least two conductive members at least partially surrounding such products and connected to a high voltage source to cause the products to engage and grip upon surfaces which receive such products. In one embodiment, cigarettes conveyed in a tube of insulating material are first charged by brushing against wire connected to a high voltage supply and are then braked by subjection to an electrostatic force, fed from the same high voltage supply and of the same polarity, applied to a semi-circular electrically conducting plate incorporated in the tube beyond the said wires. In a second embodiment, cigarettes conveyed in a tube are braked by the application of high voltage charges of opposite polarities to two substantially semicircular plate electrodes insulated from the tube and each other, and having insulated surfaces. The curvature of the plate electrodes is slightly flattened downwards. In a third embodiment, cigarettes are braked and held on a conveying drum by electrostatic forces, preferably supplemented by conventional suction means. Cigarette receiving grooves on the drum each comprises two electrodes, having insulated surfaces and insulated from each other and from the main body of the drum, and which are connected to opposite poles of a high voltage supply during that part of the rotation of the drum in which it is desired to retain the cigarettes thereon. Connection to the high voltage supply is effected by means of two concentric sets of mutually insulated segments disposed around the periphery of one end of the drum, the segments being earthed when not connected to the supply. Two groove electrode constructions are disclosed. A fourth embodiment discloses the application of electrostatic forces to the retention of a cigarette in a suitably modified holder of a known kind of apparatus for turning cigarettes end for end. In a fifth embodiment, electrostatic forces are used to hold tobacco in the tobacco filler forming channel of a forming wheel. The two sides of the filler forming channel are each formed of segments of conductive material insulated on their exposed surfaces, from each other and from the wheel itself, and the segments are connected to a high voltage supply by means of slip rings and brushes as they pass through the region in which it is desired to hold tobacco to the drum, the two sides being connected to opposite poles. A trimming device is associated with the wheel.
