Title: Control of data input/output devices
IPC: G06F13/26
Filed: 1971-12-16
Abstract: 1363687 Data processing INTERNATIONAL BUSINESS MACHINES CORP 16 Dec 1971 [30 Dec 1970] 58432/71 Heading G4A A plurality of I/O devices 41-43 are connected to a central processing unit 1 which is arranged to execute instructions for controlling data transfer between any one of the devices and memory 49 in the processor. As described an input/output instruction from memory 49 is loaded into instruction register 58. A four-bit code OP, indicating that an instruction is to be carried out, is fed to logic 86 and a signal representing the function to be effected is transmitted over function bus 46 to all the devices 41-43. A three-bit working device code representing, at a particular time, the device to be instructed is applied via bus 64 to memory address register 50 which addresses memory 49 to read out a five-bit actual device code temporarily assigned to the working device code. This code is fed on device code bus 47 to all the devices where it is compared with a local device code so that device sequence and logic control in the addressed device is enabled and stores a transmitted function. The code is also fed to an address decode 73 which decodes it to a signal on one of 32 leads to select the appropriate store 81 holding the address in memory 49 to or from which data is to be transferred with the selected I/O device. When devices desire service each applies a signal on an interrupt request line 44 to a matrix 80 which decodes the applied signals to derive a signal on the lead associated with the highest priority device requiring service. This signal is applied to encoder 74 which supplies the device code of the unit selected for servicing to all the units. The selected device, on recognizing its device code, signals via the function bus whether the interrupt is for input or output of data and it then proceeds to transmit or receive data on data bus 48. Priority matrix.-The matrix 80 for determining which device is to be serviced comprises, for each device an inverter (20-42, Fig. 2, not shown) and for each device except the device of highest priority AND gate (25-40) the arrangement being such that a device requiring service inhibits the AND gates associated with all devices of lower priority.

Title: Variable duty cycle control
IPC: H02P7/29
Filed: 1973-12-19
Abstract: 1448497 Controlling D.C. motors ALLIS-CHALMERS CORP 19 Dec 1973 [22 Dec 1972] 58769/73 Headings H2J and H2K Apparatus for supplying variable duty cycle pulses from a D.C. source to a load comprises a control pulse generator, a circuit for selectively varying the duty cycle of the pulses, a power switch PS between the D.C. source and the load controlled by the control pulses, a sensor for detecting the voltage across the power switch and for deriving a signal when the voltage across the power switch exceeds a predetermined magnitude, a protective circuit responsive to this signal for overriding the duty cycle varying circuit and reducing the duty cycle of the pulses, means producing a narrow pulse at the leading edge of each of the control pulses, and means to disable the protective circuit and thereby enable the power switch to turn on for the duration of the narrow pulse. In the embodiment shown and using the power switch to control the voltage supplied to a reversible D.C. series motor, Fig. 1 (not shown), starting with the situation where the power switch PS is off, a pulse is issued by the oscillator and triggers a monostable GPM to set a bi-stable gate G1, G2 to enable gate G3 to provide a turning on signal S1. At this time transistors Q 1 -Q 15  in the switch PS are not saturated and hence a signal on line CL is present at gate G4 from circuit SVL. The monostable pulse is also an input to the gate G4 and this nullifies the effect of the signal on line CL. The setting of the bi-stable places forward bias on lead L 0  to transistor Q 9  which allows capacitor C9 to charge via transistor Q 8  at a rate depending on the setting of a manually variable potentiometer POT. A signal appears on lead T 0  after the delay to reset the bi-stable and terminate the signal S1. If transistors Q 1 -Q 15  go out of saturation prior to the signal T 01  a signal on lead CL 1  in the absence of the pulse from the monostable GPM, terminates S1. Switch PS comprises a number of parallel transistors of which three, Q 1 , Q 7 , Q 15 , are shown, all the transistors being controlled by a constant current switching regulator DCR.

Title: Frequency summing device
IPC: H03B21/00
Filed: 1973-12-20
Abstract: 1436359 Modulators; frequency-changing; amplifiers COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT - ALCATEL 20 Dec 1973 [20 Dec 1972] 59205/73 Headings H3F H3R and H3W A device for summing two first and second sinusoidal signals S1, S2, Fig. 4, of frequency F and f respectively, comprises a first phase shifting circuit 3 providing a third signal of frequency F phase shifted by 90 degrees and a second phase shifting circuit 4 providing a fourth signal of frequency f phase shifted by 90 degrees, first and second analogue multipliers 6, 7 each comprising two inputs, the first multiplier receiving on one input a frequency F and on the other f taken from the group of four signals, while the second multipler receives the two remaining signals of the group. The outputs from the multipliers 5, 6 are fed to an adder or subtractor 7. The frequency f is variable in a band centred on f 0  and the second phase-shifting circuit 4 comprises a first elementary phase-shifting circuit 41 receiving the frequency f and having an output of equal amplitude but with phase shift depending on frequency, being 90 degrees for the frequency f 0 , together with second and third elementary phase-shifting circuits 42, 43 in cascade, followed by an attenuator 44 of attenuation factor of 3. An adder 45 has one inputs connected to the outputs of phaseshifters 41 and 44: the resultant output to multiplier 6 has a substantially constant amplitude and phase-shift of 90 degrees over the band in which the frequency f lies. The phaseshifting circuit 4 causes attenuation which is compensated for by means of an attenuator 40 in the input to multiplier 5. The elementary phase-shifters used may comprise a differential amplifier Q, Fig. 3, with the input signal fed to its phase-reversing input via resistor R1, negative feedback being applied over resistor R3, while the signal is also fed to the in-phase input over capacitor C1, this input being connected to earth over a resistor R2. In a second embodiment, both frequencies F and f can vary over a frequency band, and consequently the phaseshifter 3, Fig. 6, feeding input signal S1 at frequency F to multiplier 3 is of the same type as the phase-shifter 4 feeding signal S2 at frequency f to multiplier 5, comprising a chain of elementary phase-shifters 31, 32, 33, attenuator 34 and adder 35. In this arrangement, the attenuations in the inputs to the two multipliers are self-compensating.

Abstract: 688,662. Electric indicating systems; visible signalling apparatus. AUTOMATIC TOTALIZATORS, Ltd. Oct. 11, 1950, No. 24854/50. Classes 40 (i) and 118 (ii) [Also in Groups XIX and XL(a)] An indicator for simultaneously indicating the values under each of a number of different headings comprises a member progressively moved in one plane by a time base control and a second member successively moved in a second plane by each of a number of different indicators corresponding to the different headings, the two members controlling a universally pivoted light source. The invention is described with reference to a system for indicating the odds on a number of different horses. As shown wiper arms 3, 13 mounted on a common-shaft 4 sweep respectively contacts 2 and 12. Contacts 2 are looped along a resistor 1 the ends of which are fed by a battery 6 so that from the arm and the centre top of the battery a progressively increasing voltage is fed to a solenoid 15. Arm 13 supplies a signal from each of the resistors in bank 8 in turn to a solenoid 16. The magnitude of this signal depends on the position of a contact 11 set in accordance with the odds on the horse which corresponds to the contact 2 on which arm 3 rests. Indicator panel construction. Solenoids 15 and 16 control through flexible arms 18, 20 the orientation of a light source so that a point on a screen fluoresces. The screen is viewed through one of a number of slots 27 in a frame 25 each column representing a horse. Lines 28 on the frame enable the height of the spot to be gauged. The persistence of the screen should be such that the indication is visible for one complete revolu- . tion of the time base.
