Title: Color video signal generating apparatus
IPC: H04N9/077
Filed: 1968-05-27
Abstract: 1,206,217. Colour television. SONY CORP. 27 May, 1968 [29 May, 1967], No. 25207/68. Heading H4F. A filter 7, Fig. 6, and a screen 8'comprising spaced cylindrical lenses 8a combine to form images of an object O on a photosensitive screen of an image pick-up tube 3 in such a way that the images comprise a series of coloured areas corresponding to the various colour components of the light from the object, resulting in the production of component colour signals. The filter 7 also carries means, e.g. an array of electroluminescent light sources, for forming an image on the pick-up tube 3 which generates an index signal. Preferably the component colour signals all lie within the same frequency band, and the index signal is at a frequency lying outside the luminance signal band. In the embodiment shown the filter 7 comprises on array of parallel cyan, magenta and yellow stripes 7R, G, B, Fig. 7, carrying electroluminescent portions 12L spaced at intervals such as to generate an index signal of 6 MHz frequency, while the colour stripes are arranged such that the colour sub-carrier frequency is 4À5 MHz, for a tube scanning frequency of 1À5 MHz. A light source 14 may also be provided to generate a standard signal of 1À5 MHz frequency. A band pass filter 19 selects the 1À5 MHz signal from the composite video signal generated by the tube 3, and passes it through a gate circuit 23 driven by the horizontal blanking signals applied to a terminal 24, and then to a 1À5 MHz oscillator, which is thus synchronized with the standard signal. A band pass filter 20 selects the 6 MHz index signal and uses it to synchronize a 6MHz oscillator 28. A gate circuit 26 passes the 1À5 MHz signal in synchronization with the output from the oscillator 25, and a frequency converter converts this to the colour sub-carrier frequency of 4À5 MHz. If the standard signal source 14 is omitted a variable delay circuit 33 is required at this point. The signal is then applied via delays 31a, 31b producing 120 degree phase shifts to synchronous demodulator circuits 30R, G, B which are also supplied with the 4À5 MHz chrominance signal via a band pass filter 21, with the result that colour difference signals are derived from terminals 32R, G, B. A 0-4 MHz low pass filter 22 provides a luminance signal at terminal 32L.

Filed: 1923-10-12
Abstract: 227,509. Lawaczeck, F. Oct. 12, 1923. Impeller blades.-The forms of turbine and rotary pump blades are determined from the relationship involved, under the condition of shockless entry, between the angles formed by the projections into axial, tangential and radial planes I, II, III of the relative velocity of the flow to the runner. For all points where the flow enters the runner the angle # between the projection of the relative velocity Ce into the radial plane I and the tangent to the circle or rotation, the angle gamma between the projection of Ce into the tangential plane II and the tangent to the circle of rotation, and the angle # between the projection of Ce into the axial plane III and a line parallel to the axis, are connected by the relation tan e = tan # / tan #. The direction of the blade at any point is made to agree with that of the relative velocity Ce. Blades of helical form are determined by making the angle of inclination 8 between a generatrix of a blade and the axis about which the blade rotates equal to the angle e. The inclination of the boss is of paraboloidal form, is also made equal to the angle e as indicated in Fig. 2. Further mathematical relationships involved by the prescribed conditions are set forth in the Specification.

Filed: 1958-08-11
Abstract: 873,785. Magnetic core data-storage apparatus. BENDIX CORPORATION. Aug. 11, 1958 [Aug. 15, 1957], No. 25759/58. Class 106 (1). The switching time of magnetic elements such as cores is kept to a minimum by providing an alternative path for the current in an impedance 122, Fig. 2, in the circuit of the drive: winding conductor 116. Current normally flows through 122 and a diode 124, but an address pulse 126 enables the next clock pulse 128 to switch on transistor 104 and hence also 112 so that this current is diverted to the coredrive conductor. Fig. 1 shows in schematic form an arrangement for reading a binary digit from a selected core 12 in a two-dimensional matrix, and writing back the information after readout using a number of driver circuits as shown in Fig. 2. When clock pulses from 28 and row and column address signals are received by the appropriate driver units 40, 42 of the selected core, the core is driven to the " O " state; if it was previously set at " 1 " an output pulse 49 in a line 22 coupled to all the cores will act through transformer 50 and transistor amplifiers 54, 56 to give an output signal at 66 and reset flip-flop 60 to give a high output on line 64 (if it was already at " O " flip-flop 60 will not be reset after being set by the clock pulse) which when low energizes an " inhibit " line 24 also coupled to all the cores to prevent the selected core being set to " 1 " through drivers 70, 72 by the clock pulses delayed by parts 30-34 of delay line 38. The left-hand (" clock-pulse ") input to unit 68 is lengthened and delayed by use of two differently delayed clock pulses passed by an " or " gate 80.

Title: Railway signalling

Abstract: 1,253,289. Block signalling system. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. 23 May, 1969 [29 May, 1968], No. 26340/69. Heading B7N. In a railway signalling system in which each track block is defined by a trackside loop carrying signals for train control which are characteristic of that block, e.g. at a particular carrier frequency, a brake control characteristic signal given in a particular block can only be cancelled by a signal having a similar characteristic. Thus a train which through, e.g., defective brakes moves into a following block after receiving a braking signal is not affected by a proceed signal applied to the loop of that block. Assume a train 17 in block 11 receives a brake signal modulated on a carrier frequency fl because of the presence of a train 18 in the following block 12. The signal is picked up from the loop by aerial 20 and produces an output from receiving circuit 21 tuned to f1 and this is applied to decode unit 24 to provide a brake signal on output 249. This signal and the output from circuit 21 are applied to the inputs of switch 27 which in response to the presence of both signals provides an output 273 to block the operation of circuits 22, 23 responsive respectively to signals at frequencies f2, f3. If the train is operating correctly and comes to a halt in block 11 the blocking remains until a proceed signal at frequency f1 is received. If, however, due to faulty brakes the train runs into the next block the blocking can only be removed manually by key after a fixed time delay or by a signal transmitted by radio from a central point.
