Abstract: 1,252,673. Clocks and watches. SOC . ANON. DES ETEBS LEON HATOT. Feb.17, 1969 [Feb.19, 1968], No.8467/69. Heading G3T. In a system for synchronizing the mechanical oscillator of a timing device, and including a radio receiver 20 for receiving a periodic radio synchronizing signal, and a winding BS connected to receive the output of the receiver thereby to synchronize the oscillator, a switching device 22 is controlled by the oscillator and electrically connected to prevent energization of the synchronizing winding except when the oscillator is within a predetermined limited range of positions in which the synchronizing signal is effective and which corresponds to a small fraction of the repetition period of the synchronizing signal. The switching device 22 may be in series with the winding BS as illustrated in Fig. 2, or in the power supply circuit or a stage of the receiver 20. One form of switching device 22 comprises a transistor in the emitter-collector circuit of which the coil BS is connected, and in the base-emitter circuit of which is connected a pick-up coil, positioned in relation to a moving magnet system carried by a balance or pendulum so that the transistor is rendered conducting during a desired fraction of the period of oscillation of the balance or pendulum. In other embodiments, Figs.6 and 7 (not shown) a switching transistor is rendered conducting by pulses from a circuit maintaining the oscillations of a balance and comprising a further transistor and drive and pickup coils; whilst in further embodiments, Figs.9 to 11 (not shown) the radio synchronizing signal is applied to one or both of the drive and pick-up coils in the oscillation maintaining circuit, the transistor of which functions as the switching device. The system may also include a filtering circuit Fig. 1 (not shown) for rendering ineffective all parasitic signals received during the intervals between the synchronizing signals.

Abstract: 1296999 Electrostatographic developers AUSTRALIA DEPARTMENT OF SUPPLY SECRETARY OF 22 Dec 1969 [30 Dec 1968] 62457/69 Heading G2H An electrostatographic developer comprises a dispersion in an insulating carrier liquid 9 of insulating particles 2 which deposit on charged areas of an electrostatic latent image 11 and larger, more conductive particles 5 which acquire the polarity of the image charges and are repelled thereby unless insulated therefrom by previously deposited insulating particles 2. In operation, particles 2 start to deposit on the image and this enables particles 5 to deposit. Initially particles 5 deposit mainly on the areas of high charge gradient to produce edge development, which is required for X and y ray imaging. A uniformly  developed image may be obtained if development is continued. The developer may be prepared by precipitating pigment-resin aggregates from solvent solutions thereof. Preferred resins are  styrene but adiene copolymer, vinyl toluene acrylic copolymer; methyl methacrylate; melamine; and ethyl hydroxy cellulose resin. Development characteristics may be modified by adding particles of zirconium octoate, cobalt octoate, iodine or lead napthanote.

Abstract: 1304851 Digital measurement of area NATIONAL RESEARCH DEVELOPMENT CORP 4 Feb 1970 [6 Feb 1969] 6512/69 Heading G4H The area between a line and one co-ordinate is summed as an operator traces the line with a pointer which generates a first signal for each increment of travel in the one direction and a second signal proportional to its instantaneous position in the other co-ordinate, the area being calculated by accumulating values of the second signal for each of the first signals. In one embodiment a photo-cell moving over a graticule with the pointer provides the first signals and an oscillator whose frequency is proportional to the position of the pointer in the other coordinate provides the second signal. For each first signal the pulses from the oscillator are accumulated for a predetermined length of time, except the first nine pulses which provide a datum level.  In another embodiment (Fig. 1) movement of the pointer in the negative direction of the one co-ordinate (X) causes values of the second signal (Y) to be subtracted from the accumulated area enabling areas within a closed boundary to be determined. Potentiometers 5 and 6, driven by the pointer, provide X and Y analogue signals which are compared at 7, 8 with the count of binary counters 9, converted by digital to analogue converters 10, any imbalance causing either gate 11 or 12 to open to step up or down the counters 10 by one count. The pulses altering the X counter occur at each increment of change along the X-co-ordinate and open either gate 15 or 16 to add or subtract the Y-co-ordinate value, held in the Y counter 9a, to or from the accumulated area count held at 14.
