Title: Improvements in or relating to methods of manufacturing display scre ns for cathode-ray tubes
IPC: H01J9/227
Filed: 1961-08-03
Abstract: 916,832. Colour television tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 3, 1961 [Aug. 6, 1960], No. 28240/61. Drawings to Specification. Class 39 (1). In a method of making a multi-colour cathode-ray tube display screen in which for the application of the final phosphor a solution of a photo-sensitive binder is used after which the solution is dried and exposed to hardening radiation through the screen support, the previously applied phosphor layers are substantially unsusceptable to this radiation. The unexposed binder is then removed and the final pnosphor fills the entire surface of the screen support between the areas occupied by the phosphors previously applied. The usual thin metal reflecting layer is provided. The final phosphor layer may be applied by a method in which the binder is applied first, rendered sticky by exposure to radiation and unexposed areas removed before or after applying the phosphor layer or by a method in which the phosphor material is suspended in the binder solution. Suitable phosphors are: a silver-activated zinc cadmium sulphide for green, a silver-activated zinc sulphide for blue and another silveractivated zinc-cadmium sulphide for red. The binder may be an aqueous solution of polyvinyl alcohol containing a bichromate as sensitizer and the blue phosphor is applied last.

Title: Computer means for sequential fuel injection
IPC: G06G7/161
Filed: 1973-06-14
Abstract: 1440347 IC engine fuel injection control systems INTERNATIONAL HARVESTER CO 14 June 1973 [21 June 1972] 28352/73 Heading G3N [Also in Division G4]  In an electronic fuel injection system for an engine in which injection valves are actuated sequentially in synchronism with intake strokes of the engine, the duration of injection valve energizing pulses is determined as a function of the product of signals representing the engine speed and intake manifold pressure, the speed signal being derived from a tachometer and coupling circuit, the pressure signal being derived from a pressure transducer circuit and a coupling circuit, the coupling circuit associated with the pressure transducer including a conditioning circuit which provides an output which is a predetermined non-linear function of the pressure signal. The system shown in Figs. 1 and 3 is substantially the same as that described and shown in Application 28300/73. As an alternative, the timer circuit shown in Fig. 3 may have a signal representing the product of the speed and pressure signals applied to terminal 59 and a reference signal applied to terminal 60. The tachometer circuit 62, the pressure circuit 64, the conditioning circuits 61, 63 (see Division G4), the fuel inhibit circuit 67, the driver circuits 31-38 and the sequence circuit 49 are described with reference to Figs. 4-9 (not shown). In the circuit shown in Fig. 10, the pressure signal is applied at terminal 251 to a conditioning circuit 252 whose output is applied to one terminal of an amplifier 276. Engine rotation triggered pulses are applied at terminal 298 to a tachometer circuit whose output is applied to control the gain of amplifier 276 so that amplifier 276 supplies an output signal representing the product of the conditioned pressure signal and the speed signal. The product signal is amplified at 303 and 311 and is then applied to one input of a comparator amplifier 315, the other input being received from a ramp circuit which includes a capacitor 328. Each injection operation is triggered by a pulse applied at terminal 340 which sets a flip-flop 322 and causes a monostable multi-vibrator to produce a pulse to initiate charging of capacitor 328 after a time delay determined by the speed signal at a circuit point 287 in the tachometer circuit. When the charge across capacitor 328 reaches the amplified product signal at the one terminal of amplifier 315, this amplifier provides a pulse for resetting flip-flop 322 to stop injection.

Title: Method of recording, analysing, converting or utilising local or time distributions or successions of energy
IPC: H04N5/782
Filed: 1927-10-31
Abstract: 279,909. M³ller, C., (Assignee of Sch÷nicke, A.). Oct. 29, 1926, [Convention date]. Calculating-apparatus. - Relates to apparatus for recording, analysing, converting or utilizing energy which is distributed over a certain spatial or temporal range and which can be analysed in respect of space and/or time. The invention is mainlv described with reference to spectrum analysis, but is also applied to other purposes, such as sound records, and the transmission of pictures electrically. The object is to obtain and utilize a result which correctly represents the local intensity at a point notwithstanding the necessity of observing or recording the same over a slot or the like of definite substantial width. The mathematical method for balancing the undesired integration due to the width of the slot necessarily used, involving a method of differentiation, is fully described in the Specification and involves the use of slots adjacent to that comprising the point at which the intensity to be measured or utilized occurs. A proportion of the sum of the measured intensities of the adjacent slots is subtracted from the measured intensity of the central slot and the result represents to an appropriate scale the intensity at the point under consideration. The various apparatus described are designed to measure or receive these various intensities and to effect the computation indicated so as to record, transmit, or utilize the actual energy at the desired point. A device for correcting a curve of intensities, e.g. intensity of luminosity of a spectrum, which has been obtained in the ordinary manner by utilizing a slot of some width, and for drawing a corrected curve is shown in Fig. 1. Three rulers are utilized and set to the values of the central slot and to the values, given by slots one on each side of the central slot and connected together and to stylus 30 in such a manner that a fraction of the sum of the values on the side rules 12, 13 when adjusted to the curve 5, 6, 7, 8 is subtracted from the value of the central rule 10 when line 11 is adjusted to intersect the curve and the stylus 30 is thereby moved to a position giving the correct value, which is a fixed proportion of the result of the previous adjustments. The movements of the rules 12, 13 are transmitted by wheels 16, 17 having cams 20, 21 to a rod 22 to which is connected a rack 26 as shown. An adjacent rack 29 carrying the stylus 30 is operated from the rack through gears 27, 28 so that the movement of the stylus 30 is a definite proportion of the resultant of the movements of the rules 12, 13 and the rule 10 upon which the rules 12, 13 are carried. By moving the points 6, 7 and the line 11 round the curve a fresh curve is drawn by the stylus 30 giving the correct values.
