Binary data is stored on magnetic tape in the form of signals of two frequencies corresponding to the ones and zeros of the data. In the embodiment shown the data are fed in at two voltage levels at 24, and these are amplified and shaped at 28 and fed to a voltage-controlled oscillator 30. The oscillator is described with reference to Fig. 2 (not shown) and produces 800 kc/s. and 1200 kc/s. signals corresponding to the zeros and ones of the data input. The signals are then passed through a frequency divider 32 and to the recording head 18 of the tape mechanism. The frequency divider scales down the frequencies by an integral factor dependent on the tape speed, and may be manually or automatically operated. The signals are read from the tape by a head 20 and fed to a pre-amplifier 38 and a limiter 40 to remove variations in amplitude. Filters 42, 44 each pass one of the frequencies which are fed to a further amplifier 46 and an output device 26 which may be a flip-flop.

Filed: 1968-08-09
Abstract: 1,240,529. Aerials. BRITISH AIRCRAFT CORP. 22 Oct., 1969 [9 Aug., 1968], No. 38292/68. Heading H4A. A linear-to-circular polarization converter comprises a sandwich having two outer skins 6, Fig. 3, and an intermediate filling 8 of lower dielectric constant. The skins 6 may be made of fibreglass/resin laminate, and the filling 8 may be made of fibreglass/resin honeycomb. Each skin 6 supports an array 7 of parallel conductive wires, the two arrays being parallel to each other. When a wave which is linearly polarized at 45 degrees to the direction the array 7 impinges upon the converter, the electric field component perpendicular to the arrays experiences a phase delay in passing through which is due to the dielectric sandwich alone, whereas the components parallel to the arrays experiences a lesser phase delay due to the susceptances of the arrays offsetting the effect of the dielectric sandwich. At a predetermined frequency, the first-mentioned delay is 90 degrees, the second-mentioned delay is 0 degrees, and the amplitudes of the two components are equal so that conversion to circular polarization takes place. A polarization converter as described may be formed into a fixed radome over an aerial (Fig. 1, not shown) or into a protective cover 3, Fig. 2, attached to a radio reflector 4.

Fig. 1 shows a hand held device comprising a frame 13 having a shoe 19 for engagement with the corner of a box to which pressure sensitive adhesive tape is to be applied, and an L-shaped aperture 25 having legs 29, 30 in which block 24 is slidably mounted and movable by pneumatic jacks 68, 70. Block 24 pivotally supports a pair of arms 44, 46 on pin 48 (only shown in Fig. 4), the arms supporting leaf spring 34 and the pair of brushes 43. The arms are biased by spring 49 so as to protrude from the frame as shown in Fig. 1. The path from the reel 51 of tape 53 is defined by corrugated rolls 54, 56, 58, 59. The head also supports leaf spring 39, and the frame supports a trigger 15 and pneumatic valve operating arms such as 90, 106. At the beginning of a cycle, the tape end is engaged with the brushes as in Fig. 4. Application of the shoe 19 to a box corner deflects the arms 44, 46 to within the frame, which disengages the tape end from the brushes and applies it to the box, and readies a pneumatic circuit. The latter is then operable by trigger 15, which causes operation of jack 68 to traverse the head along leg 29 applying the tape by spring 34, and then of jack 70 to traverse the head along leg 30 applying the tape by spring 39. During the latter movement, the arms 44, 46 are free to be pivoted by spring 49 so that the brushes can re-engage the strip, so that when the latter is severed by knife 124, the strip end is held by the brushes. The jacks automatically return the head to its starting position.

Abstract: 854,797. Cables. ALGEMENE KUNSTZIJDE UNIE N. V. Dec. 3, 1958 [Dec. 24, 1957], No. 39047/58. Class 36 In a high-tension cable having a number of thin insulating layers of a solid organic artificial substance between the conductor and its sheathing, the layers being separated from one another only by oil, the layers consist of films or foils which are highly resistant to the action of the oil and have been finely scratched on at least one side so as to provide freedom of movement .for the oil. Examples of insulating materials are polymethylene terephthalate, polyethylene terephthalate, polyamides, polyethylene, polypropylene, polybutylene, polybutadiene, polyvinyl chloride, polystyrene, and cellulose ester, such as cellulose acetate, the material preferably having a dielectric constant close to that of the oil. The scratching is preferably effected by grinding discs which are traversed rapidly from side to side of the film as it is advanced slowly longitudinally. The film may alternatively be " goffered " so as to provide parallel rectilinear scratches across the film, the distance between the scratches being at least three times the depth of the scratch. The films may be preheated to reduce the tendency to shrink at the working temperature, and film-thickness may be graded. from the conductor outwards.
