Title: Improvements in or relating to data records and devices for recording and reading back coded information
IPC: G06K19/06
Filed: 1959-02-02
Abstract: 906,429. Statistical records. SVENSKA DATAREGISTER A.B. Feb. 2, 1959 [Feb. 12, 1958], No. 3646/59. Class 106 (1). Data, e.g. numerals, are recorded on a strip in a binary code as shown in Fig. 4, having four mark positions for each digit, a mark "S" always being present to control sensing and a check mark " C " being provided where necessary to make the number of marks odd. The white rectangles in Fig. 4 represent code positions where no mark is present. The recordings may be made in ordinary ink or radio-active or magnetic ink, a type face as in Fig. 5 being used. This approximates to the size of the type faces used for printing out invoices in cash registers or similar machines, and may be used instead. In Fig. 1 the code areas are in a different arrangement. Sensing.-If the marks are of ordinary ink e.g. from a typewriter ribbon, they are sensed photo-electrically. For this purpose the strip is fed over a table T, Fig. 8, and the image of the recording is thrown on a matrix of photocells FS, FC and F1-F8, there being a similar column for each digit column of the record. There is also a photo-cell FR for a mark R adapted to reset the reading circuits before the associated columns of data are sensed. Light from the record passes to the photo-cells through slots B in a mask which prevents interference between positions. The photo-cell signals are amplified in amplifiers AR, AS, AC and A1-A8, Fig. 6. The outputs from amplifiers AC, A1-A8 pass via And gates NC, N1- N8 to flip-flops VC, V1-V8. The outputs from amplifiers AS and AR control a flip-flop VS connected to an impulse generator G. In operation, the resetting mark R comes under the photo-cell just before the other marks reach sensing position and the flip-flop VS is reset. This resets all the other flip-flops VC, V1-V8 to cancel the value previously sensed. When the control mark S reaches sensing position, the signal from photo-cell FS sets flip-flop VS causing the generator to give a pulse which opens the gates NC, N1-N8. The marks C and 1-8 reach their sensing positions slightly after the control mark S and any marks present set corresponding flip-flops VC, V1-V8.

Title: Improvements in or relating to turbo-jet engines equipped with post-combustion means
IPC: F02K3/10
Filed: 1952-02-15
Abstract: 709,667. Gas turbine jet propulsion plant. COMPAGNIE ELECTRO-MECANIQUE. Feb. 15, 1952 [March 5, 1951], No. 4075/52. Class 110(3) [Also in-Group XXXV]  In a system for initiating re-heat in a turbo-jet engine having a variable section gas discharge nozzle and pilot and main re-heat burners, ignition of the pilot burners is detected by the consequent change in turbine outlet pressure, which change causes opening of the discharge nozzle and supply of fuel to the main burners. In Fig. 2 a condenser 3 is varied by a differential bellows (not shown) responsive to the difference between the outlet and inlet pressures of a turbojet engine so that an electric motor 13 adjusting the fuel supply to the main re-heat burners is controlled to maintain the pressure difference constant (see Group. XXXV). Re-heat is introduced by moving a two-way switch 24 to the position shown, contact d initiating fuel supply to the pilot re-heat burners and contact c initiating their ignition. The potential Uc of a resistancecapacity network, derived from a potentiometer. 29, and applied to the grid circuit of valve 14, maintains a relay 25 de-energized until rise of turbine outlet pressure due to ignition of the pilot burners influences condenser 3 so that relay 25 and, in consequence, relay 27 are energized. Disconnection of potentiometer 29 due to energization of relay 27 permits potential Uc to rise to a maximum and then fall to zero under the influence of the two time constants of the resistance-capacity circuit. This allows motor 13 to move in the direction necessary to turn on the supply of fuel to the main re-heat burners despite the rise of pressure due to the pilot burners until pressure falls due to the opening of the jet discharge nozzle initiated by contacts k, l of relay 27. In a modification relay 25 is replaced by a switch operated by increase of pressure due to ignition of the pilot burners.
