Abstract: 1401642 Developing electrostatic latent images AUSTRALIA DEPARTMENT OF Mfg INDUSTRY SECRETARY OF 26 Sept 1972 [30 Sept 1971] 44501/72 Heading G2H An electro-photographic latent image, or a dielectric pattern image produced thermally or by pressure, is developed by two successive components of a preferably liquid developer, and the components are so chosen that as the polarity of a developing electrode changes first one component is selectively deposited on the image, then the other component is deposited on those parts of the image area which did not receive the first component. The first component acts as a mask during the second part of the development, and may be a colourless or opaque white resin, mingled with more-conductive toner particles in an insulating liquid. During the first stage of development an electrostatic bias holds the conductive toner particles away from the latent image, then reversal of the bias forces the toner particles on to the image.

Title: Radar target simulators
Inventor: STAGLES ALWYN FREDERICK
IPC: G01S7/40
Filed: 1963-11-15
Abstract: 1,085,071. Radar simulators; aerials. ELLIOTT BROTHERS (LONDON) Ltd. Nov. 5, 1964 [Nov. 15, 1963], No. 45208/63. Headings H4A and H4D. To enable a radar system to be tested a radar target simulator is provided whereby a radar pulse is received, heterodyned down to an I.F. pulse, delayed for a period consistent with the target range to be simulated, heterodyned up to a pulse of the original radar frequency, and then attenuated by an amount consistent with the target range and size to be simulated, to provide a simulated target echo pulse for transmission back to the radar system. The radar pulse is received by aerial 1, Fig. 1, and is fed, via circulator 7 and fixed attenuators 11, 12, to a first mixer 13, where it is heterodyned with a signal from local oscillator 14 at such a frequency that the output pulse from the mixer has a frequency of 150 Mc/s. The pulse frequency is further heterodyned down to 15 Mc/s. in mixer 16, with the aid of the output of local oscillator 17 at 135 Mc/s. The frequency of the output of the mixer 16 is monitored in discriminator 36 and any frequency deviation from 15 Mc/s. causes a servo control to operate to readjust the frequency of oscillator 14. The I.F. pulse at 15 Mc/s. is delayed in a mercury delay line 19 under the control of a servo 31 which is fed with signals representing the range and range rate to be simulated. The delayed I.F. pulse is heterodyned up to its original radar frequency by means of mixers 21 and 23 and local oscillators 14 and 17. The system so described should be such that the amplitude of the radar pulse at the output filter 24, is the same as its amplitude at the input of attenuator 20. This equality is checked by means of comparator 43 comparing said amplitudes and feeding any correcting signal to control a variable gain amplifier 20. The delayed radar pulse is now passed to attenuator 25 where it is attenuated in accordance with the simulated target area. The attenuated radar pulse is further attenuated in attenuator 26 which is varied, via specially profiled cam 32, by servo 31, such that as delay 19 is varied to simulate the range, the radar pulse is attenuated by attenuator 26 according to the fourth power of the range. The thus delayed and twice attenuated radar pulse is retransmitted by aerial 1. The operation of the simulator may be checked using pulse generator 64. The waveform of the I.F. pulse may be observed on C.R.O. monitor 39. The aerial 1 may be a simple horn radiator mounted on a tripod and backed with a screen of radar wave absorbing material, Fig. 2 (not shown), or the horn may be mounted on a carrier which is movable along rails under the section of a motor-driven pulley when it is desired to vary the bearing of the simulated target. The rails are mounted such that they can be pivoted from horizontal to vertical, Fig. 3 (not shown). Where noise-free simulator is desired the aerial may be replaced by a probe, which is inserted in a hole in a waveabsorbing cone which is placed over the radar transmitting aerial, Fig. 2 (not shown).

Abstract: 1446046 Charge coupled imaging device RCA CORPORATION 27 Sept 1973 [2 Oct 1972] 45266/73 Heading H1K In a charge coupled imaging device including two adjacent rows of sites in a substrate, located under conductors common to the two rows, at which sites charge carriers produced by an image can be integrated and stored and subsequently transferred to a read-out area, a bus embedded in the substrate between the rows is maintained at such a potential that it acts as a drain and means are provided for establishing between the sites and the bus a potential barrier which varies in response to voltages present on the conductors but is such that charge in excess of the storage capacity of a site flows over the barrier to the drain rather than to adjacent sites. In one device in which charge is transferred by three-phase voltages comprising a P type silicon substrate, from which the conductors are separated by a uniform 2500  layer of silicon and provided with diffused N type buses, the potential barrier is formed by a diffused P type region containing 6 x 10<SP>16</SP> acceptor atoms/cc located on each side of the bus. In an alternative structure for operation with overlapping two-phase voltages, illustrated in Fig. 11, in which each charge transfer electrode consists of interconnected aluminium and polysilicon strips 30, 32 to facilitate unidirectional transfer the barriers are due to the thickness of oxide being increased to X 03  adjacent the drains. In one form of this structure the minimum distance of the aluminium conductors from the charge transfer channel is less and in the other it is greater than X 03 , the former arrangement protecting against optical overloads only during the light integration phase while the latter also affords protection during charge transfer. Operation of the various structures is described in detail. Reference has been directed by the Comptroller to Specification 1,413,092.
