Title: Improvements in or relating to electrical means for controlling the position of an object
IPC: B66B1/36
Filed: 1959-09-11
Abstract: 872,501. Control of motors. BROWN, BOVERI & CIE. A.G. Sept. 11, 1959 [Sept. 11, 1958], No. 31055/59. Class 38 (3). A travelling nut M1 is driven by a machine and actuates contacts L, H, B in sequence to switch the machine from high to low speed, disconnect it, and apply a brake. If the machine over-runs a desired limiting position, nut M2 should actuate safety switch S to put the machine out of operation. A contact Z for checking the operation of the safety device produces an additional signal which, as regard to time, lies between the signals produced by contacts L and H. Closure of the contact Z by the nut M2 energizes relay R which closes holding contact R1. Shortly afterwards contact H2 is closed by nut M1, but this has no effect since contact R2 is open. If contact Z is not promptly closed, however, closure of contact H2 completes a circuit connected to terminals U whereby the machine is brought to a standstill and an alarm signal given. In a modification, pulses from generators driven by the machine are applied to electronic counters Z1, Z2, an adjusting device EL (set at " 600 " for example) producing a positive pulse at terminal L to switch the machine to a low speed. At a count of " 675 " adjusting device EH disconnects the machine and at " 685 " adjusting device EB initiates braking operation. Counter Z2 is connected to adjusting device ES and can be adjusted to the number " 695," so that, when the machine over-runs and this number is reached, a positive pulse is applied to terminal S to stop the machine independently. An adjusting device EZ is set to coincide with the device EH whereby, during normal operation, pulses occur simultaneously in conductors b, c and differential relay R is not operated. When the safety device is defective, however, contact R1 closes temporarily to energize a protective and signalling circuit. In another arrangement, the pulse occurring at terminal L energizes relay R which has a self-holding contact in series with a contact of another relay. This second relay is energized by the pulse in conductor b and causes relay R to drop out. If the pulse is missing from the conductor b, occurs before the pulse at terminal L, or after the pulse at terminal H, then relay R remains energized after the pulse has arrived at terminal L so that, when a-pulse arrives at terminal H, a safety circuit is closed, Fig. 3 (not shown).

Title: Method and apparatus for maintaining the voltage at a capacitor
IPC: B01J27/00
Filed: 1972-07-04
Abstract: 1399912 Automatic control systems SHELL INTERNATIONAL RESEARCH MAATSHCAPPIJ BV 4 July 1972 [6 July 1971] 31247/72 Headings G3N and G3R [Also in Division H3]  A process control system comprises a capacitive analogue store of the type in which leakage is corrected by resetting the store to the nearest level of a step wave, the resetting being effected through a bi-directional path when the wave approaches to within a given range of the stored voltage so that leakage causing both increase and decrease of charge is corrected. In Fig. 1 the value of a variable 2 is set into the storage capacitor 1 by momentarily operating a switch 4. The output is taken through a unity gain amplifier 5 and is compared at 8 with a step wave 9. When, during the riser of a step, the voltage difference becomes less than half the step height the output of the comparator switches a Schmitt trigger 10 to initiate operation of a monostable circuit 11. This closes a switch 12 so that the capacitor charges or discharges to the level of the next step. Means, not shown, between the comparator and the trigger prevent further action once the triggering is complete and a diode circuit, not shown, prevents false operation when the step wave returns to its initial level. The input signal of a storage may be derived from sensors responsive to temperature, pressure or flow-rate. Fig. 4 shows a fail safe digital control system in which storage circuits according to the invention are connected in each control line. Normally, switches 26 are in the left hand position so that the voltage across the storage capacitors 27 follows the respective output from the computer 20 but, upon failure, switches 26 open and the capacitor stores the last control value, this being refreshed periodically as described above. In an alternative computer control system Fig. 5 (not shown), storage circuits according to the invention are coupled between the input lines of the computer and a corresponding output storage arrangements. One input of the output storage arrangement is the difference between the input signal to the computer and the output of the first mentioned storage arrangement which difference normally is zero but in the event of failure, the stores according to the invention hold the last value and the difference between the input and output values, which is now equal to the last value, is fed to the output store. On failure of the computer the output store memorises the signal.

Title: Improvements in or relating to leading mechanisms for typecomposing or typecasting and composing machines
IPC: B41B7/04
Filed: 1931-11-18
Abstract: 376,614. Printers' composing- machines. ELLIOTT, R. C. and MONOTYPE CORPORATION, Ltd., 43, Fetter Lane, London. Nov. 18, 1931, No. 31986. Addition to 349,680. [Class 100 (iii).] Leading-mechanism.-Leading-mechanism of the kind described in the parent Specification is modified so as to adapt it either for intermittent leading, in which a part only of the composition is leaded, or for continuous leading, in which the whole of the matter is leaded. Intermittent leading is effected under.the action of signals in the record-strip, and continuous leading is effected by mechanical means independently of the strip. The leading-galley B, Fig. 2, is, as heretofore, moved towards and away from the gate or rule A<5> of the type galley by a lever D<2> and a motor D, controlled by a valve-device D<6>, which can be operated both from the record-strip and mechanically by projections &c. on the galley cam. The valvedevice contains a piston-valve D', Fig. 8, which is maintained in its highest position by a spring D<8>, in which position air from a constant supply enters by a conduit D<9> and passes by a conduit D<10> to the motor D. The two components of the leading-signal admit air by ports D<11>, D<12>, Fig. 4, below and above the valve respectively. Two spring latches E, E<1>, Fig. 8, serve to hold the valve in its intermediate and lowest positions respectively. When continuous leading is required, the latch E<1> is locked out of action. A projection on the galley cam depresses the valve, which is held down by the latch' E. In the further action of the machine, a second projection on the cam trips the latch and releases the valve at the proper moment for the operation of the leading-galley. When intermittent leading is required, the latch E<1> is brought into use. The latches E<1>, E are successively tripped by projections on the galley cam, so that the valve rises to its highest position, when both components of the leading- signal are present. When a line is not to be leaded, it is accompanied by only one component of the leading-signal, the effect of which is to depress the valve after the latch E<1> has been tripped, so that the valve is again engaged by the latch.
