Title: Improvements in or relating to photo-sensitive layers and methods of manufacturing such layers
IPC: H01J29/43
Filed: 1941-03-10
Abstract: 547,806. Photo-electric layers. CINEMATELEVISION, Ltd., and SOMMER, A. March 10, 1941, No. 3255. [Class 39 (i)] A photo-electrically sensitive layer is formed by depositing a layer of a fluoride of a metal other than an alkali or alkaline earth metal on to a metallic layer, e.g. silver, and evaporating an alkali metal, preferably caesium, on to the fluoride layer. In an example, silver fluoride is evaporated on to a base layer of silver in an evacuated envelope, and caesium is then distilled on to the fluoride layer whilst the layer is maintained at a temperature of approximately 150-200‹ C. The composite layer is then baked until maximum sensitivity is obtained. Before or after this baking, additional silver or silver fluoride may be evaporated on to the layer, or the layer may be superficially oxidized to alter the spectral sensitivity.

Patent GB-1459444-A (GB)
Title: Moving target indicators using synthetic aperture processing techniques
IPC: G01S13/90
Filed: 1973-01-24
Abstract: 1459444 Radar EMI Ltd 11 Feb 1974 [24 Jan 1973] 3687/73 Heading H4D A sideways looking synthetic aperture radar has its video signal produced by a displaced phase centre aerial and processed by a single delay line and MT1 comparison circuits to eliminate doppler signals from fixed (relative to ground) objects, and the remaining doppler video signals from moving objects are processed by one or more correlator means having staggered centre frequencies and total bandwidth equal to the pulse repetition frequency fs of the transmitted pulses. The invention relies on the principle that whatever the frequency of the main component of the spectrum of the doppler signal of the moving object, the fold over of the components about the multiples of the pulse repetition frequency fs will always give a component within the bandwidth of the correlator means. If the speed of the moving object gives rise to a doppler frequency f D  when it is on the axis of the radar beam and the centre frequency of the reference frequency sweep in the correlation steps is not f D , then the correlation will give an incorrect along track position from the object. A plurality (e.g. 4) of narrow bandwidth correlators having centre frequencies fk 1 = -#fs, fk 2  = -#fs, fk 3  = +#f s ,fk 4  = +#fs (a, Fig. 3), are therefore used, having a total bandwidth within Œfs/2, such that, with the doppler signal falling within one of the correlator bandwidths, the position error, although still present, will be small. For a main doppler component f D =2(Vt/#) the doppler signal spectrum is shown at b, Fig. 3. This is weighted by the effect c, Fig. 3, of the MT1 canceller, such that the signals produced by the correlators have relative amplitudes given by d, Fig. 3. A doppler signal can give consecutive output from two correlators, and to combine these into one signal, the output of the correlators can be combined via delays. Fig. 4 shows a complete radar, wherein the output of the MT1 canceller, is divided into in-phase and in-quadrature components for respective processing by the four correlators. The output of the correlators are combined by squaring and adding to give the outputs S1, S2, S3, S4. These may be combined (Fig. 5, not shown) by adding or amplitude discriminated before combination by respective threshold stages (Fig. 6, not shown). The radar beam need not be at 90 degrees to the aircraft flight axis. If the p.r.p. of the transmitted pulses is varied in dependence on the aircraft's speed, such that the aircraft travels a constant distance between pulses, the number of p.r.p's over which it is necessary to perform the correlation is constant. The variation of p.r.p. varies the MT1 canceller blind speed.

Abstract: 884,530. Linkwork. SCHRODER, H., and HOPPE, F., [trading as SCHRODER & HOPPE APPARATEBAU], and SCHROTER, H. O. Feb. 3, 1959 [Feb. 3, 1958], No. 3869/59, Class 80 (3). [Also in Group XXXIV] A multiple-stroke tensioning and holding lever mechanism, for example, for hand brakes of heavy road and rail vehicles, comprises a hand lever 1 pivoted on a movable pivot 3 to a transmission lever 2 connected at 21 to the device to be tensioned, and pivoted on a fixed pivot 4 to a fixed frame 5 provided with ratchets 8, 9, for engagement with separate pawls 10, 11 pivoted on the hand lever 1, and serving not only to hold the mechanism against release of tension, but also as alternative fulcra about which the hand lever can be manually pivoted during tensioning to provide increased mechanical advantage. Compression springs 19, 19<SP>1</SP>, arranged between pivoted abutments 17, 18 on the hand lever 1, and the transmission lever 2, cause the hand lever 1 to abut a stop 20 on the transmission lever 2, and a stop 16 on the hand lever to hold a spring-loaded pawl 11 out of engagement with ratchet 9. By depressing a spring-loaded plunger 13 in the hand lever 1 the holding pawl 10 is disengaged from the ratchet 8 and tension can then be relieved by moving the lever anti-clockwise. To tension the device the hand lever 1 is rotated clockwise with transmission lever 2 about fixed pivot 4, until the load is sufficient to overcome compression of the springs 19, 19<SP>1</SP>, whereupon the hand lever rotates relative to the transmission lever about the pivot 3 and the pawl 11 is free to engage the ratchet 9 under spring load, thus providing a fixed fulcrum for further pivotal movement of the hand lever, resulting in considerably increased mechanical advantage, and also further compression of the springs. The latter may eventually pass dead-centre and subsequently assist the application of thrust. When the hand lever has reached its limit of clockwise movement it may be rotated anti-clockwise, when pawl 8 engaging ratchet 8 acts as a fixed pivot and pawl 11 slips, to apply further thrust to the transmission lever, the springs 19, 19<SP>1</SP> operating in the opposite sense.
