Title: Remote-Action System
Inventor: SAKIC BORIS
IPC: H04Q9/14
Filed: 1967-05-02
Abstract: 1,178,856. Electric selective signalling. BROWN, BOVERI & CO. Ltd. 2 May, 1967 [4 May, 1966], No. 20334/67. Heading G4H. A central station 1 transmits a sequence of signals to a select sub-station 2, 2<SP>1</SP>, the first signal initiating the transfer of data from counters into stores and resetting address counters 11, 11<SP>1</SP> at the associated sub-station, the second signal causing the address counter 11, 11<SP>1</SP> to step onwards one digit and cause transmission of the portion of the store associated with the address represented by the count, together with the address, to the central station 1 where the address is compared with the address of the required data in a comparator 18, further " step onwards " signals being transmitted to the said station 2, 2<SP>1</SP> until the required address is reached. The address and data are then printed and the counters holding data at the sub-stations cleared by a third signal. A selector device 6 stores a programme determining which station is to be called and the address of the required data at that station. The selector 6 enables the associated transmitter 8, 8<SP>1</SP> to send the first signal which is of a first frequency and duration. When the second signal which is of a second frequency and duration is transmitted the address counter 11 causes read-out of the store and a signal comprising a synchronizing word (which is two 5-bit groups), the address of the data and the data (which are binary coded decimal signals in two out of five code together with this signal inverted) is transmitted. At the central station the synchronizing word is continuously compared at 17 with an identical synchronizing word which is time displaced until the two words are in phase. The address words are then compared and if they are identical the address and data are printed by a printer 21. If, however, the data is incorrect it is printed in red. If the address is not the required one, an instruction originator 12 causes another signal to be sent to step the counter 11 until the required data is received. The data is then erased by a third signal of the second frequency but having a third duration.

Title: Improvements in or relating to field responsive phosphors
IPC: H05B33/14
Filed: 1956-07-02
Abstract: 828,216. Luminescent materials. WESTING- HOUSE ELECTRIC CORPORATION. July 2, 1956 [July 8, 1955], No. 20395/56. Class 39(1). A method of preparing an electric field responsive phosphor which is not responsive to U.V. radiations and which can be used in a flashing sign with an illuminated background, comprises mixing-1 mole of at least one of the group ZnS and ZnSe, from 0À05 mole per cent to 2 mole per cent Cu activator, a coactivator of at least one of the group consisting of a halogen, Al, Ga, In and Tl in at least about the same order of magnitude as the Cu activator and not exceeding 10 mole per cent, and from 10-<SP>3</SP> to 10-<SP>2</SP> mole per cent of at least one of the group consisting of Fe, Co, and Ni-and firing the mixture in an inert atmosphere such as nitrogen, neon or argon, at about 800‹C. to 1250‹C. for at least one half hour. The halogen co-activator can be introduced as a halide, e.g. CuI 2 . The fired material can be washed with potassium cyanide, sodium cyanide and acetic acid. It is stated that firing some of the copper activator and the co-activator will be lost and that the amount of copper remaining will be between 10-<SP>2</SP> and 1 mole per cent with equivalent amounts of the co-activator. It is also stated that commercial ZnS or ZnSe, if used, usually contain from 10-<SP>4</SP> to 2 mole per cent of ZnO which is not harmful. Several examples are described. In the construction of the flashing sign with an illuminated background shown in Figs. 1 and 2, the viewing portion 18 of the sign 10 consists of a sheet of glass having applied to its inner surface a coating 20 of tin oxide forming an electrode. Coated over the tin oxide in the form of letters in the phosphor 14 above described, and coated over the remainder of the tin oxide is an organic-type dye or other phosphor 16 which can be excited only by a source 26 of U.V. radiation. Both phosphors are preferably enbedded in a transparent or translucent dielectric material 22 such as methyl methacrylate in the proportion of 1 part phosphor to 3 parts dielectic. A second electrode 24, which may be of aluminium, is coated over the phosphor-embedded dielectric 22. The electrodes 20 and 24 are conneected to an A.C. source, e.g. of 500 volts and a frequency of 60-5000 cycles, which can be alternately energized and de-energized. In a specific example the phosphor 16 comprises a 0À1% solution of Rhodamine B mixed with a plastic such as polyethylene, and the electrodes 20 and 24 are spaced 0À3 mils (0À008 mms.) apart. In a modified construction the phosphor 14 and the dielectric material may be in separate layers, e.g. a layer of phosphor 2 mils (0À05 mms.) thick and a layer of mica 1 mil (0À025 mms.) thick, and mica being transparent if adjacent the electrode 20. Reference has been directed by the Comptroller to Specification 783,613.

Title: Frequency-reducing valve circuits
IPC: H04N5/06
Filed: 1936-07-24
Abstract: 475,595. Valve generating circuits. RADIOAKT.-GES. D. S. LOEWE. July 24, 1936, No. 20556. Convention date, July 27, 1935. [Class 40 (v)] A back-coupled valve oscillator is accurately maintained at a frequency which is a subharmonic of a control frequency by applying the control voltage to a further grid within the valve, and impulses of the sub-harmonic frequency are taken off across a resistance in the anode lead. The Figure shows a pentode valve with a tuned anode circuit 10, 11 back-coupled to a coil 9 in the circuit of the inner grid. The screen-grid is held at a fixed voltage, and the control voltage from a source 15 is applied through a condenser 14 and resistance 21 to the outermost grid 4. When a tetrode valve is employed, the control voltage is applied to the outer grid. The circuit 10, 11 is approximately tuned to a fraction of the control frequency, but the frequency generated is held precisely at the fractional value. Unilateral impulses of the sub-harmonic frequency are derived across an adjustable resistance 19 in the anode circuit. The duration of such impulses may be varied by varying the negative bias 13 on the outer grid 4, or by varying the amplitude of the control voltage. When very short impulses are desired, the control voltage may be a higher harmonic, e.g. the third or fourth, of the desired frequency. The control frequency may be produced by the rotation of a slotted disc and the resulting current amplified and filtered before application to the grid 4. The system is suitable for interlaced scanning in television. Specification 453,852 is referred to.

Abstract: 360,829. Boot &c. stiffeners. BRITISH UNITED SHOE MACHINERY CO., Ltd. and MELLERIO, L. P., Union Works, Belgrave Road, Leicester. July 10, 1930, No. 20855. [Class 17 (ii).] Boot and upper-end stiffeners are weakened or rendered permeable to air and moisture within an area spaced well away from the margin, e.g. in the case of the rmoplastic stiffeners by subjecting them to rolling pressure under a hot die. Stiffeners as described in Specifications 317,144, [Class 17 (ii), Boots and shoes, Construction of], and 344,069, may be made in this manner by removing excess impregnant from desired localities. In one method, a blank cut from material impregnated with thermoplastic material is subjected to hot die pressure to denude the rear and outer margins of impregnant and to obtain a thin margin. At the same time, impregnant is expelled to a considerable extent all over the blank except over a crescent shaped area, as shown, where it is heavily charged, and which may follow the toe cap line. The blank and upper may be fused together to ensure correct location in the boot &c., or the die may be formed to leave spots of excess impregnant near each corner for this purpose. A heated press as described in Specification 244,507, [Class 17 (i), Boots and shoes, Apparatus for making, &c.], may be used, and the blanks may be heated before treatment, as described in Specification 348,533. Specification 236,600, [Class 17 (ii), Boots and shoes, Construction of], also is referred to.

Filed: 1944-11-01
Abstract: 599,076. Radiolocation. GENERAL ELECTRIC CO., Ltd., and SHARPE, J. Nov. 1, 1944, No. 21409. [Class 40 (v)] An intensity modulated cathode ray tube display system employing a two-colour screen such as that described in Specification 598,545 composed of luminescent materials with different build up and after glow periods is arranged to give an improved colour contrast in the visible image by increasing the amplitude of the modulating signal pulses for certain scanning periods. When such a display is used as a P.P.I. in a radar system, an element of the screen, the red luminescence of which builds up and decays at every scan as indicated by the dotted curve R, Fig. 2, will, if corresponding to a stationary object, have the green luminescence (full line curve G) build up to a predominant level after a number of successive scans. Permanent echoes will thus appear green. Elements of the screen corresponding to moving targets will not be similarly excited on successive scans and the red luminescence will predominate, moving targets thus giving a red indication. If the modulation intensity on certain scans is now raised so that all signals excite the green luminescence with the longer build-up period, both stationary and moving objects will produce green indications for that scan. In the normal intermediate scans however, since the indications from moving targets will have shifted they will appear in the normal red colour and the image presented by a moving object will be red, interrupted by green corresponding to each highmodulation scan.
