Title: Improvements in or relating to electrical circuitry for controlling or indicating physical conditions
IPC: G05D23/24
Filed: 1964-09-16
Abstract: 1,083,743. Automatic control. HONEYWELL Inc. Sept. 16, 1964 [Sept. 20, 1963], No. 37878/64. Heading G3R. An electrical control apparatus responsive to variations in the valve of a physical condition comprises an amplifier, having an input from a sensor responsive to the condition, delivering a pair of signals varying in mutually inverse relationship, a means controlled by one signal to derive a control output varying in dependence on the sensed condition and a further means controlled by the other signal modifying the output when the value of the sensed condition passes into a preselected range. As shown, a thermistor 12, responsive to the temperature in an enclosure 10, is connected in a bridge circuit with resistors 28, 30, 32 and 33. Included in the same arm as the thermistor is a resistor 35 to compensate for line voltage variation and a transistor 34, compensated for temperature by a thermistor 86, to provide a fail-safe action in the event of thermistor 12 being open-circuited. The output from the bridge is applied to a differential amplifier 18, comprising transistors 19, 20. The output from transistor 20 is applied through a transistor 41 to control the charge of a shunt capacitor 43 and the output from transistor 19 is applied to a capacitor 46 shunted by a diode 47. Capacitors 43, 46 are connected in polarity adding relationship to control the time firing of a unijunction transistor 48 which produces a pulse of current through a primary winding of a transformer 50 to control the firing of silicon controlled rectifiers 51, 52 determining the energization of a heater 11 for the enclosure 10. 50% of full load power to the heater 11 is provided when the bridge is balanced, transistors 19, 20 then conducting equally to cause SCR's 51, 52 to fire at the 90 point in each half cycle. With an increase in thermistor resistance due to a fall in temperature, transistor 19 conducts more and charges capacitor 46 in a shorter time to advance the firing angle of the SCR's and increase the energization of heater 11. With a reduction in thermistor resistance, transistor 20 conducts to maintain transistor 41 fully conductive and effectively short out capacitor 43, the firing angle of the SCR's is thus retarded to reduce the energization of heater 11. A second differential amplifier, Fig. 1B (not shown), is connected to lines 90, 101 Fig. 1A, and through a transistorized capacitive memory arrangement controls a SCR to maintain an indicating light energized to show that a given departure from bridge balance has occurred even though the condition of balance or unbalance of the bridge has subsequently been restored.

Abstract: 523,325. Fluid-actuated valves. HORTA, J. A. Dec. 30, 1938, No. 37922. Convention date, Jan. 6. [Class 135] A valve device for automatically discharging measured quantities of liquid comprises a variable-capacity chamber 5 constituted by a shell 6 which slides within a fixed cylinder 4 and on a fixed piston 11, and a main valve member 8 carried by a reduced part 6a of the shell and supporting a restricted feed inlet member 7, allowing the passage of liquid from the main inlet 2 to the chamber 5. The inlet pressure acting on a greater area within the chamber 5 than on the valve member 8 normally keeps the main valve closed. The pressure within the chamber 5 may, however, be released by a spring-pressed auxiliary valve 12 operated by a push-button 15. The valve 12 seats on a member 10 supporting the piston 11. The auxiliary valve stem 13 passes through a gland 17 in the valve cover 14. The support member 10 has apertures 18 for the released liquid to pass via a passage 19 to the outlet 3. The quantity of liquid discharged depends on the time taken to refill the chamber 5 through the feed inlet member 7.

Abstract: 1478489 Micro-programming COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE CII HONEYWELL BULL 3 Sept 1974 [3 Sept 1973] 38472/74 Heading G4A A micro -prgrammed data processing system includes a central processor controlled by microinstructions stored in a control store formed by a read-only store and a reserved area of main store, programme instructions being stored in the main store. When the address of a micro-instruction has been formed and stored in register 4 (Fig. 3) the highest order bit indicates whether it is in main store 11 or read only store 13 and is decoded in a logic circuit 12 which if necessary enables the main store, store 13 always being addressed. A register 15 stores the boundary address between the micro-instruction and the software, read out of date and programmes and access to channel programmes only being permitted if the address is equal to or exceeds the boundary address. The micro-instruction address is formed using the circuitry of Fig. 2 (not shown) by adding the base address of a segment held in register (1) (derived from the segment table) to the page number (represented by the first eight bits of the address in an address register (4)) in an adder (2). The adder output together with the offset within a segment represented by the lowest eight bits in the address register is fed to a unit (3) which calculates the next address and feeds it to a register (7) for transfer to the address register. Normally the unit (3) increments by one the current address to obtain the next address unless there is a change of page or segment. If a sub-routine is effected the return address is held in a register (5) and if an interrupt occurs the address to which the microprogramme would have gone is held in a further register (6).
