Title: Process control system
IPC: G05B11/32
Filed: 1971-06-04
Abstract: 1356982 Automatic control systems MELYEPITESI TERVEZO VALLALAT 4 June 1971 [13 June 1970] 19118/71 Heading G3R In a system in which a plurality of process variables are controlled by a like number of detectors and correctors by sequentially switching a single two or three point controller, disturbance caused by switching transients is prevented by providing a delay device after the controller so that the correctors do not respond until after the transient condition has terminated. The variables (unspecified) of a liquid 1 fed continuously into and out of a tank are measured and the corresponding signals on lines 4, 5, adjusted as necessary at 6, 7, are sequentially switched at 8 to an amplifier 9 and thence to an indicator 10 and controller 11. 12 is the delay unit whose output is switched, also at 8, to correctors, e.g. valves, 13, 14. The controller 11 effectively operates by pulse width modulation since it produces a pulse from the end of the delay until the output of amplifier 9 reaches a predetermined value, and this depends upon the time constant of the amplifier (its output changes exponentially from the end of the transient) and the magnitude of the measured variable.

Filed: 1944-10-09
Abstract: 631,934. Feeding preforms and powder to muliti-cavity moulding presses. GENERAL ELECTRIC CO., Ltd., HARRISON, W., and HICKLING, F. J. Oct. 9, 1944, No. 19376. [Class 87 (ii)] Pellets 5 of moulding powder contained in tubes 6 disposed in a preheating oven 3 drop into recesses 9 in a charging plate 7, and the plate 7 is then pushed to the left, clear of the oven, by a handle 18, into a moulding press where the pellets drop into moulding cavities. The oven is thermostatically heated by steam or electric means. The bottoms of the tubes are normally closed by an apertured plate 10. The bottoms of the recesses 9 are normally closed by an apertured plate 15, which moves to the left with the plate 7, but as both plates move into the press, plate 15 is checked by a stop while plate 7 moves on, whereby the bottoms of the recesses are uncovered and the pellets drop out. Starting from the position shown, the operator grasps the handle 18 and rocks it counterclockwise about a pivot 19 disposed in open-ended slots 17 in the frame 16. This rocking movement straightens a toggle 23, 24 linking the handle and the plate 7, thus moving the plates 7, 15, 10 a little way to the left to register the recesses with the tubes, the plate 10 being moved by a pawl 25 on the plate 7. As the toggle straightens, a handle extension 21 disengages the pawl and springs 12 return plate 10 to the position shown. The handle 18 is then used as a simple push rod to move plates 7, 15 into the press. Pawls and racks (not shown) prevent reversal of the plate 7 before completion of its movement into the press. Gravity- or spring- controlled tumblers 28 support the column of pellets above the one or two required to drop into the plate 7 (see Specification 631,935, [Group XXXI]). Instead of pellets, powder may be fed from the containers.'

Abstract: 215,233. Luxton. W. J., and Green, W. A. Aug. 3, 1923. Soldering.-In a can-soldering machine of the type in which the cans are moved across a framework with their edge to be soldered dipping successively in flux and solder troughs, cylindrical cans are rolled across the machine by an endless band running on pulleys which are mounted on shafts carried by a pair of articulated frames. The apparatus mav be applied to a machine as described in Specification 195,129 for soldering prismatic cans after first removing the cantoppling gear. A pair of brackets 32 are secured at the top of the framework. to each of which is pivoted an arm 30. The arms are connected by a rod 33, to which are pivoted bell-crank brackets 36, 37. These brackets are connected together by a rod 38 and are connected by links 35 to the upper ends of the brackets 32 so that when the arms 30 are raised or lowered by racks 29 engaging pinions on a shaft 27 driven by worm gear from a hand wheel 25, the brackets are moved parallelly towards and from the inclined frame so as to adjust them to cans of different diameters. The arms mav be secured to the brackets 32 in adjusted position through quadrant slots. Intermediate brackets and linkages may also be provided. The brackets 36, 37 are provided with shafts 24 for carrying the pulleys 23 of an endless band 21 for Tolling the cans along the inclined frame with their lower edges dipping successively in the flux trough and in the solder trough 3. The pulleys can be adjusted on their shafts so that the band engages the middle of the can and are driven by a belt passing over a pulley 39, pairs of pulleys 40, 41, and pulleys 42 connected by a clutch 43 to the shaft 15. This shaft, when soldering either prismatic or cylindrical cans may be driven by worm gearing 14 from a shaft 13 which has a four-speed steppedcone pulley so that the speed of the machine can be adjusted to allow the edge of the can to remain in the solder until it is heated to the temperature of the solder. The shaft 13 may have a hand wheel 20 for use when adjusting the cradles for operating prismatic cans. The cans at their upper ends rest on an adjustable angle bar 5 and at their bottoms against a shaft 6 which is rotated in a direction to prevent them riding up. This shaft is adjusted to vary the depth to which the cans dip in the baths, by screwed collars 19 on slides which are adjusted at right angles to the inclined frame by screws and hand wheel 18.

Filed: 1939-07-08
Abstract: 531,894. Conveyers. KING, Ltd., G. W., and KING, D. M. July 8, 1939, No. 19954. [Class 78 (i)] Pivoted load-carrying trays attached to conveyers are each tipped for dumping the load at its own pre-selected station. The trays 14 are pivoted at 15 to hanger bars 13 supported by rollers running on. the rigid track 12 and traversed by the endless driven chain 10. A pawl 22 riding on the periphery of a series of loose discs 24 acts through the link 21 to maintain a lever 16 in such position that the pin 20 on the tray is supported in the shorter arm of the bayonet slot 18, thus maintaining the tray horizontal. The arms 27 on the various discs 24 are set to different angles to engage fixed cams near the track. Each discharge station has its own particular arrangement of spaced cams and although the arms may be operated by the cams momentarily against restoring springs at intermediate stations, it is only at the selected discharge station that the operation will result in the recesses 26 in all discs being in register. When this occurs the pawl enters the recess, the link 21 is forced down and the lever 16 tilted until the pin 20 is released and the tray allowed to tilt. In some cases the setting arms 27 may be adjustable angularly on the discs 24 for additional presetting movement, but normally they are fixed to the discs and the adjustment is made by moving stops against which they abut.
