Title: Digital scan converter
IPC: G01S7/10
Filed: 1973-05-21
Abstract: 1388233 Radar; scan conversion HUGHES AIRCRAFT CO 21 May 1973 [2 June 1972] 24128/73 Heading H4D and H4F  Video signals resulting from scanning a scene in a first pattern, e.g. those from a standard pulse radar 10a with an antenna rotating in azimuth, are displayed using a second, different pattern, by first converting the analogue video signals to digital form (10b) and storing the digital signals-e.g. one radial line at a timein a buffer store 10c, in positions corresponding to the first scan pattern. Each such position is converted to its equivalent in the second scan pattern and the converted positions used to store the digital signals in a random access memory 12 in accordance with the second pattern. When a whole field has been thus converted and stored, memory 12 is read out in accordance with the second pattern into a display 33, via a digitial to analogue converter 32, the display being scanned according to the second pattern. In the radar display shown, the azimuth # of the antenna is represented by an analogue signal fed to an analogue to digital converter 23. Read-only memories 15 and 16 produce digital signals representing Sin 0 and Cos # respectively which are fed to one input of respective multipliers 17, 19. The other inputs of the multipliers are fed by range ramp counter 18 with a digital representation of the range R being scanned. The range pulses feeding counter 18 are also used in controlling the storage positions in buffer 10c. The mulipliers 17, 19 thus give digital outputs respectively representing the cartesian co-ordinates X, Y of the second TV raster type pattern, equivalent to the radial co-ordinates R, 0 of the first pattern viz. X = R sin 0, Y = R cos #. The outputs are fed, via mode switches S-M in the position shown and address switches S-A in the position not shown, to the memory 12 to control the read-in of the data stored in buffer 10c. When a whole field has been stored in memory 12, switch S-A is positioned as shown and readout signals from counter 13 read out the data in memory 12, line element by line element, and line by line, according to the second pattern. The counter 33 also controls the sweep circuits for the CRT display tube 33. If the radar signals are supplied according to a type B scani.e. orthogonal, range/azimuth axes-multipliers 15 and 16 are by-passed and the R, # digital signal are fed directly to second input terminal of mode switch S-M

Abstract: 963, 751. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 7, 1961 [July 29, 1960], No. 24615/61. Heading G4H. Interchangeable spare components are provided which may be switched into replace malfunctioning components in a cryogenic circuit. The circuit 50 is an array of conductors connected by cryotron current inhibitors 78, 80,.... 98, 100 so that, in response to two inputs out of a, #a, b, #b on vertical conductors 52 to 55, current on line 74 is steered either to terminal 66 to represent a function f1 =ab v #ab or to terminal 68 to represent the function #f1, and current on line 76 is steered to either the terminal 70 to represent a function f2 = #ab or the terminal 72 to represent the function f2. Should one of the vertical conductors or the crytrons associated with it fail there are two spare vertical conductors 114 and 116 one of which may be switched in to replace the malfunctioning conductor. Assume conductor 52 to have failed. A current is sent through line 196 to operate inhibitors 180 and 188 Then current is applied to either line 192 or line 193 to select one of the spare conductors. This directs current on line 52 to either line 146 or line 168.

Title: Improvements relating to arrangements for the transmission of communication signals by pulse code modulation transmission
Inventor: BARROW CHRISTOPHER WILFRED MER
IPC: H03M1/00
Filed: 1966-06-02
Abstract: 1,162,373. Selective signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 22 May, 1967 [2 June, 1966], No. 24665/66. Heading G4H. In a P.C.M. system, samples of a speech signal are encoded using a contracted floating point representation. The first digit interval is used for transmitting signalling information via gate GA21. In the second digit interval the polarity of the sample is determined by PI, and if necessary the polarity is reversed by SRCA as a result of the setting of MA to the A state and MA1 to the B state, a sign bit being transmitted via BE1. Subsequently in this same interval, MA5 is set to the B state to supply a reference current 81 to node D of a ladder network attenuator ATT via SA4 which is open as a result of MA2-MA4 being in the A state. ATT produces an output of 64, 32 ... 2, 1 units when a reference current I is applied to nodes A-G respectively. In digit intervals 3-5 comparisons are made between the sample and the output of attenuator ATT with the 8I reference current applied initially to node D and then to nodes on one side or the other of node D, depending on the results of the comparisons, so that by the fifth interval, the output of ATT is the largest power of 2 multiple of 8 units which is less than the sample. If the sample is less than 8 units, GA8 is opened to turn off MA5. Outputs are taken from MA2- MA4 as shown to generate the exponent bits via BE2-BE4. At the end of the fifth interval, MA6 is turned on so that a reference current 12I is applied to the selected node of ATT, and subsequent comparisons are made in intervals 6-8 with combinations of reference currents 4I, 2I, I to generate the numerical component bits. The six-bit number thus generated is the complement of the binary floating point representation, the most significant " 1 " bit not being transmitted since it must occur for all levels except 0-7 units. Alternatively, the number generated may be regarded as the complement of the binary equivalent of the quantizing step number in which the sample lies. The receiving end is similar in construction. The polarity bit is stored and sets a polarity inversion circuit, identical to SRCA, to the appropriate condition during interval 6. The exponent bits are also stored and operate the appropriate one of seven current switches during interval 6. Also during this interval, provided the exponent includes at least one " 0 " bit, a reference current of 8I is applied to the node of an attenuator selected by the exponent. The numerical component bits select appropriate reference currents 4I, 2I, I for application to the selected node. An additional ¢I reference current is added to reduce the quantizing error. Since build-up of the reconstituted sample does not commence until interval 6, each sample of a multiplexed series may be held until the fifth interval of the next channel period.
