Title: Image reproduction systems
IPC: G03F3/08
Filed: 1972-12-04
Abstract: 1400806 Facsimile apparatus CROSFIELD ELECTRONICS Ltd 19 Nov 1973 [4 Dec 1972] 55902/72 Heading H4F In the facsimile reproduction of a monochrome or coloured original, localized modification, i.e. retouching, of density values (corresponding for example to flesh tones) which occur only within selected (flesh) areas of the original is effected by tracing the boundary of each area of the original within which modification is to take place to derive boundary-defining signals which are stored and used during subsequent scanning of the original to cause the facsimile output signal or set of facsimile colour output signals to be modified only when the corresponding scanned element is within a traced boundary. Modification of the signals within a traced boundary may also be effected when they define a predetermined hue or range of hues, a flesh tone correction of the type described in Specification 1,294,191 being used (Fig. 4, not shown). The boundary-defining signals may be generated by manually rotating a cylinder carrying the original and manually displacing a reference device along a lead screw parallel to the cylinder axis to thereby cause the reference device to trace the boundary of each area, photo-electric pulse generators being coupled to cylinder and reference device so that, by counting the resulting pulses, Y and X co-ordinate signals for the boundary of each area are obtained. These signals are stored and when the coordinate signals corresponding to the position of the analysing head of the facsimile scanner lies between these stored co-ordinate signals the video output signals from the analysing head are fed via a special tone correction unit instead of a standard tone correction unit to the exposing head of the facsimile apparatus. The correction units may comprise matrix stores loaded in a preliminary operation with corrected colour information as described in Specification 1,369,702. The tone correction arrangement may include an interpolator of the type described in Specification 1,369,702, the colour component signals being digitized (Fig. 3, not shown).

Patent GB-1447680-A (GB)
Title: Data processing systems
IPC: G06F12/10
Filed: 1973-12-10
Abstract: 1447680 Data processing system SIEMENS AG 10 Dec 1973 [18 Jan 1973] 57054/73 Heading G4A A data processing system having a virtual memory system is arranged to transfer data between the working store and peripheral devices, there being a chain list store containing an entry for each real page in the working store, each entry containing the real address of the next page in the working store to be used in a data transfer, and means arranged when a page boundary is crossed during a transfer to access the chain list store to obtain the real address of the next page to be used in the transfer. Accessing the chain list store may also be used to locate the next page during normal program operation as well as for I/O operations. In an I/O operation a real working store address consisting of a page part and a byte part is stored in register DARP to access, via decoder DEC1, a section DSP of the working store from or to which data is transferred to or from peripherals PG. The byte part of the address is incremented (or decremented) in adder ADD to produce a new real address which is transferred to DARP to continue the I/O operation. If a page boundary is crossed, indicated by a carry from the highest bit position of the byte part of the address, a signal U12 prevents the transfer of the old page part of the address to register DARP (the carry not having been added into the page part). The old page part is concatenated with a base address from a register KBR to access, via decoder DEC2, the chain list store KSP which may be permanently resident in the working store. From the resulting accessed entry corresponding to the old page a new, real page part is obtained and is fed to register DARP together with the modified byte part from adder ADD to form a new real address to continue the I/O operation. The chain list store may contain in each entry two real page addresses corresponding to the succeeding and preceding pages in the sequence of virtual pages for use when the adder ADD increments and decrements respectively the address in DARP, the appropriate address being selected in accordance with a single bit in the I/O command which also serves to control the adder appropriately. The chain list store may also contain conventional checking bits to initiate appropriate action in the event of a fault. Several modifications are mentioned, e.g. the base register KBR may be dispensed with and register DARP may be replaced by a store containing one address for each of a number of I/O operations.

Title: Fluid Signal Summing Modulator and Amplifier.
IPC: F15C1/20
Filed: 1966-12-22
Abstract: 1,166,267. Fluid regulation. JOHNSON SERVICE CO. Dec.22, 1966 [Dec.27, 1965], No.57523/66. Heading G3H. A fluid signal summing modulator and amplifier comprises a reference chamber 9 through which a main stream 4 is projected from an inlet 2 to an aligned outlet control orifice 7. In the region of the orifice the main stream 4 impacts with an opposed stream 5. A primary control signal line 11 terminates in an orifice 12 to give a jet for deflecting the main stream. A secondary control signal line 14 connected to the chamber 9 varies the pressure drop across the primary orifice 12 and hence indirectly the deflection of the main stream. A summed output signal at 10 is taken from an output chamber 8. Resistances 15, 16 in the input signal lines are equalized so that there is equal pressure gain with respect to the two signals. In a multi-stage amplifier, Fig.2 (not shown) four of the devices are connected in circuit to provide an input stage (17), three amplifying stages (18, 19, 20), and a pneumatic relay (21) is added as a power output stage. A common input line (22) is supplied through a regulator 24. The secondary controls of the two intermediate stages are referenced to the secondary of the input. The secondary of the output stage and also the relay can be switched to the reference line 25 or to atmosphere by switches (26, 27). The circuit includes a feedback restrictor 28 from the output and a resistor to establish a balanced condition in the absence of signals. The signal line resistances may be chosen to give a pre-selected gain characteristic or made equal to give equal pressure gain with respect to each signal.

Filed: 1972-12-14
Abstract: 1352674 Electronic fuel control system BENDIX CORP 14 Dec 1972 [13 Jan 1972] 57760/72 Heading G1N In an I.C. engine, electronic fuel injection system having electrical sensors, including an intake manifold pressure sensor 18 and an engine speed sensor 19, and a computer 17 responsive to signals from the sensors to provide injector control signals, a deceleration control circuit is responsive to an operator's demand for deceleration, this circuit including a time rate of change sensor 29 responsive to the signals from the pressure sensor 18 to provide a first signal when the manifold pressure decreases at a rate faster than a predetermined rate, and a control switch 26, 31 responsive to the first signal to control the computer in such a way as to curtail or terminate injection. As shown, the switch 26 is also responsive to signals from an engine speed comparator 25 and a pressure comparator 27. The comparator 25 compares a signal from the speed sensor 19 with a reference signal representing a predetermined engine speed to provide an output signal when the engine speed is above this predetermined value. The comparator 27 provides an output signal when the manifold pressure is above a predetermined pressure value. The switch 26 is responsive only to coincidence of signals from the comparators 25, 27 and the first signal from sensor 29 to set output switch 31 (a bistable multivibrator) which then generates an inhibitory signal. Another comparator 28 is provided to produce an output signal when the manifold pressure is above a second predetermined value, a reset switch 30 being provided and being responsive to coincidence of an output from comparator 28 and a second output from sensor 29 indicating a rate of charge slower than the predetermined rate, to reset the switch 31 and terminate the inhibitory signals. Details of the circuitry of Fig. 2 are described with reference to Figs. 3 and 4, (not shown). In an alternative embodiment, Fig. 5, (not shown), the speed comparator is omitted. Signals from other engine sensors may be added to the set and reset switches 26, 30. The inhibitory signal may be used to completely terminate injection by preventing the generation of injection control pulses by the computer, Fig. 6, (not shown), or may be used to prevent the generation of at least one injection pulse in each cycle, using a switch, Fig. 7, (not shown), or to shorten the injection pulses using a delay circuit, Fig. 8, (not shown). Signals from engine sensors may be applied to modify the delay period.

[Also in Division G1] In a direct current amplifier having a resistance 44, 46, 48 connected, between the collector electrodes of a pair of transistors 34, 38, a feedback resistor 50 is connected in a direct current path between the collector electrode of one transistor and the base electrode of the other transistor and a further feedback resistor 52 is connected in a direct current path between the collector electrode of the other transistor and the base electrode of the one transistor so that when an input voltage is connected between the base electrodes current is fed back to the control electrodes through the resistors 50, 52, the values of the feedback resistors 50, 52 and the resistance 44, 46, 48 being such that the current fed back is substantially equal to the current drawn by the base electrodes from the input source so as to provide a high input impedance. The feedback is adjusted by resistors 44, 46, 48 so that the transistors 34, 38 do not draw any current from the input voltage, to be measured, applied at 10. Also the positive feedback is restricted due to the high value of the resistors 50, 52 so that oscillation is prevented. : Negative feedback is provided by resistors 58, 60. The output transistors feed a meter 44 which is calibrated to read-voltage, current or resistance in ohms. Range adjustments are provided by resistors 14-28, 76 and 78 and switches 30 and 80. For current measurement the resistors 14-28 used for voltage measurement are replaced by smaller value resistors. For resistance measurement the unknown, resistance is connected in series, with a reference resistor and a local voltage source, such as a battery and the voltage across the unknown resistor is applied to the bases of the transistors 34, 38.
