Filed: 1959-10-23
Abstract: 927,768. Aerials. LAN JEN CHU. Oct. 23, 1959, No. 35984/59. Class 40 (7). An aerial system wherein a two-conductor unbalanced transmission line is connected to a two-conductor balanced transmission line, comprises means for preventing currents flowing in the unbalanced line from affecting the field between the balanced conductors. As shown, a coaxial feeder 5, 7, Fig. 2, extends within one of the conductors 11 of a balanced pair 11, 13, the inner conductor 7 being connected by an extension 7<SP>1</SP>, Fig. 3, to the other conductor 13 of the balanced pair. The point of connection is situated half-way along the balanced pair and the length of the connection 7<SP>1</SP> is less than oneeighth of a wavelength at the operating frequency. The outer conductor of the coaxial line makes conductive contact with the inner surface of conductor 11. The balanced conductors are conductively connected by bridges 23, 25 at their extremities and are supported at intermediate points by dielectric spacers 15. The conductors may be of square section. The balanced line constitutes a feed for an aerial array comprising hollow cylindrical dipole elements 3, 3<SP>1</SP>, 3<SP>11</SP>, 3111 which surround the conductors 11, 13 and are alternately connected at 24, 26 to opposite members of the pair. The whole array is surrounded by a protective cylinder 1 of dielectric material. In the modification of Fig. 7, conductor 11 is of greater diameter than the other member of the pair which, in this case, is divided into three sections 13, 13<SP>1</SP>, 13<SP>11</SP>. Extension 7<SP>1</SP> of the inner conductor 7 is connected to the mid-point of section 13 and the extremities of section 13 are connected to the mid-points of sections 13<SP>1</SP>, 13<SP>11</SP>. The extremities of sections 13<SP>1</SP>, 1311 are connected to cylindrical dipole elements 3, 3<SP>11</SP>, 103, 10311, the remainder of the elements being connected to the conductor 11. The sections 13<SP>1</SP>, 13, 1311 are arranged alternately on opposite sides of the conductor 11 to prevent interaction between the fields in the various portions of the balanced line. The end of section 13<SP>11</SP> may be provided with a tapping 53 leading to a further antenna, e.g. an upwardly directed helix. A uniform phase variation of about 12¢ degrees between dipole elements may be provided to give an upwardly tilted beam.

Filed: 1958-11-14
Abstract: 889,858. Automatic voltage-control systems. TECHNICAL OPERATIONS Inc. Nov. 14, 1958 [Sept. 22, 1958], No. 36687/58. Class 38 (4). [Also in Group XL (c)] A D.C. voltage stabilizer comprises three transistors in series between the source and load, the biasing of the transistors being arranged to equalize the voltage drops across each transistor when these voltage drops are at the allowable maximum. Three alternative biasing arrangements are disclosed. In every case, three transistors Q1a Q1b, Q1c are connected in series between a source pi/ni and a load po/no, and the first transistor Q1a forms a compound connected amplifier with an auxiliary transistor Qd1. The compound amplifier is controlled via a valve or transistor amplifier A1 by the difference between a portion of the output voltage tapped off a potentiometer R1 and a reference voltage shown as VR1. The bases of the transistors Q1a, Q1b, Q1c are linked by resistors R1a, R1b, R1c, so that changes in the base current of the controlled transistor Q1a effect corresponding changes in the bias of transistors Q1b and Q1c. In the first embodiment, the resistors R1a, R1b, R1c are graded, R1b being twice the value of R1a, and R1c twice the value of R1b. In the second embodiment, Fig. 2 (not shown), the resistors are replaced by Zener diodes which are initially biased to be conducting, but which cut-off in sequence as the base current rises in the associated transistor. In the third embodiment, Fig. 3 (not shown), the resistors R1a, R1b, R1c are of equal value, but graded resistors are introduced in series with each collector.

Abstract: 1,271,394. Facsimile scanner. CCI AEROSPACE CORP. 23 July, 1969 [3 Sept., 1968], No. 36942/69. Heading H4F. [Also in Divisions C4 and G4] A head for scanning a surface with which it is in close proximity, i.e. without using lenses, comprises an array of element 10 with a common electrode a, electroluminescent zinc sulphide layer b, transparent electrode c and glass layer d, each element including a partially transparent photoconductive layer f, e.g. of copper doped cadmium sulphide between transparent In 2 O 3  electrodes e, g, so that light from layer b passes through and is reflected back to, layer f to vary the signal current in electrodes e, g, according to the matter on the scanned surface, and means for sequentially scanning the output signal from ones or groups of the elements 10. The layer f may be continuous, in which case it is preferably 40-50% transmissive, or it may be opaque and have openings for the passage of light therethrough. In a modified construction electrodes e and g are omitted and chromium vapour deposited electrodes are disposed at opposite sides of the layer f. The signals are compared with the output of a reference element 10 positioned over a blank portion of the scanned surface, using a differential amplifier, so as to compensate for, e.g. variations in the surfaces scanned, Fig. 5 (not shown). The array may be a single row of elements, Fig. 2 (not shown), which may be divided into groups which are sequentially scanned on one electrode e, the elements in each group being sequentially sampled on the other electrode g as that group is scanned, Figs. 9-11 (not shown). Alternatively the electrodes g may be connected to a common lead and all electrodes e sequentially commutated. The signal current from each element is passed through a common load resistor to give a signal voltage, and a thin film diode between the electrodes of each element serve to isolate it from the other element. Alternatively, Fig. 6, the array may consist of a number of columns of elements, the columns being scanned sequentially to give a plurality of simultaneous row outputs which may be compared with stored arrays in a unit 64 to distinguish various characters. The bottom row of elements locates the bottom of each line of characters and then, via a control unit 57, permits a clock 59 to operate a scanning commutator 60. Commutator 60 is described in detail with reference to Fig. 7 (not shown).

In Fig. 1, the support comprises a spring- stirrup 2 clipped over the arm 1; the stirrup carries an adjustably-mounted scale 5 and a pointer connected to a feeler bearing on an upper roller 10. In Fig. 3, the support comprises a housing 3 within which is a magnet carried by a leaf-spring 32b fastened to the housing, so that the magnet is free to move to secure the housing when the device is applied to the arm, and is retained against a strip 32a on the housing when the device is not in use. The support also carries a scale 35 and a feeler 39 which is long enough to bear on two upper rollers. In another form, Fig. 5 not shown, when the housing is magnetically held on the arm, the feeler is rotatably mounted so that it can be moved to bear on the lower roller. In Figs. 8 and 10, the housing is carried by the upper roller and the feeler bears against the under side of the arm. In Fig. 8, the support is a U-shaped stirrup 83 the legs which are shaped, as e.g. at 83a, to embrace both rollers of the front twin upper pair, and has a rearward extension with a magnet 83c in contact with an upper apron roller. The feeler is a two-armed pivoted lever 89, one arm having a piece 89a which is urged against the underside of the arm 81 by a spring 86a attached to the other arm which bears against the operating member 85a of a scale 85. The stirrup may be made wider so that it can be supported on the lower rollers (831, Fig. 9 not shown). In Fig. 10, the support 103 extends along one side of the arm and is bent around the back of the arm. It is supported on the front upper roller 100 and rests at the back on the support bar 100d of the arm.
