Title: Improvements relating to automatic control apparatus for use in the manufacture of water gas and other cyclic processes
IPC: C10J3/24
Filed: 1929-03-04
Abstract: 310,508. Humphreys & Glasgow, Ltd., (Assignees of Soc. de Construction d'Appareils pour Gaz Ó l'Eau et Gaz Industriels). April 27, 1928, [Convention date]. Producers.-In apparatus for the control of water gas apparatus and other cyclic processes, the parts to be operated are moved by rotary cams which are driven at constant speed and actuate levers which are themselves connected to the members to be operated or to servomotors which operate them, means being provided to change rapidly from automatic to manual operation. The operated member is connected to the piston of a hydraulic cylinder 1 controlled by a three-way valve 2 operated by a lever 5 and link 4 attached to a lever 3, the short arm of which has a roller 7 coacting with a cam 8 fixed to a wheel 9 on a shaft 10 driven at constant speed. On rotation of the shaft 10 the cam 8 depresses the lever 3 and places the operated member in the working position until the roller 7 leaves the cam 8, when the lever 3 is automatically raise operated member does not obey the co caused to return automatically to its sa tion by being connected by means 11 12 carrying a bar 14 which remains in position so that a stud 15 on the cam with a stop 16 and displaces the bar it actuates levers 21, 23 against the a spring 35, and by a rod 25 and bell-c 27 withdraws a bolt 29 which releases a weighted lever 30, causing its shaft 32 to rotate and a fork 33 to slide the whole system of cams 8 into disengagement along the shaft 10. By this means the levers 3 and valves 2 resume the safety position, a tappet 18 contacts with a projection 19 on the bar 14, which is moved to the right and restores the parts to the safety positions. In manual operation, a rod 36 is caused to engage in a rack 39 to retain the lever 3 in position. For carrying out one or more operations more rapidly a wheel 42. Fig. 3, is keyed to the shaft 10 and has cams 43 which actuate through a rod 44 the handle of a rheostat 48 which controls the current supply to the shaft 10, and causes the speed of the mechanism to vary during the whole cycle; the lengths of the rod 44 may be altered by adjusting a screwed sleeve 49. In case of current failure, or overload, the weighted lever may be released electrically to put the apparatus into the safety position. During hand operation an interlocking device between two levers may be provided to prevent wrong movements of the levers being made, and a safety device is provided, whereby, if the operated member jams or the transmission seizes, the apparatus is put into the safety position.

Abstract: 268,329. British Thomson-Houston Co., Ltd., (Assignees of Jones B. W., and Chapman, C. H.). March 26, 1926, [Convention date]. Electromagnetic switches; contacts; switches, latching and unlatching.-In order to prevent the contacts of electromagnetic contactors from welding together when they re-engage after they have separated due to the repulsive action between them caused by abnormal currents therein while the contactor is closed, an automatic latching arrangement for the movable contact is provided which can only be released manually. As shown in Fig. 2, if the spring- pressed contact 11 is forced from the fixed contact 10 by the electrodynamic action of the current passing through the contacts, a spring- pressed detent 24 slips behind the extension 25 holding the contact 11 away from the fixed contact 10 as shown in Fig. 3. Thus the contacts cannot immediately re-engage, while they are heated by the arcing between them, on reduction of current effected by the magnetic closure, and the latching plunger has to be disengaged by pressure of the knob 28 before the circuit can again be closed.
