Title: Automatic electric control system for a combined printing and ammonia gas developing machine for sensitive papers
IPC: G03B27/30
Filed: 1963-02-05
Abstract: 1,020,931. Automatic temperature control. S. MITA. Feb. 5,1963 [Feb. 5, 1962], No. 4753/63. Heading G3R. A combined printing and ammonia gas developing machine for sensitive papers, which is of conventional construction and operation, Fig. 2 (not shown), is provided with the automatic control system of Fig. 1 which includes two thermostats 11, 16 to ensure that the ammonia liquid supply pump is not started until the ammonia gas chamber has reached a desired temperature, that the energization of a pilot lamp 28 indicates the attainment of a further higher desired temperature at which developing may be commenced, and that after the developing operation has been terminated the motors 9,10 driving the machine conveyer belts and cooling and exhaust fans continue to run for a predetermined period. Operation of the machine is commenced by actuation of the "ON" button 4 which closes the contacts A1, A2, A3 of a relay 2 to energize the motors 9, 10. Simultaneous energization occurs of a light 30 inside the glass printing cylinder and of a space heater 22 and an ammonia liquid evaporating heater 29 inside the ammonia gas chamber, the heater 22 being controlled by the contacts C1 of a relay 17. When the temperature in the gas chamber is high enough to evaporate liquid ammonia the thermostat 11 closes to energize a relay 6 and so start a motor 8 driving the ammonia liquid supply pump. When the temperature in the chamber has risen to a further desired value, the thermostat 16 opens to de-energize the relay 17 and thus the heater 22, closure of contacts C2 of relay 17 energizing a relay 23 to light the pilot lamp 28 indicating that the temperature suitable for developing has been reached. Thereafter this temperature is maintained by operation of the thermostat 16 to switch the heater 22 on and off, the relay 23 being self-holding to keep the lamp 28 continuously alight. When the developing operation is finished the "OFF" button 5 of relay 2 is actuated to de-energize members 8, 17, 22, 23, 28, 39, 30, the motors 9, 10 continuing to run until thermostat 11 opens to de-energize the relay 6. Hunting of the contacts of relays 6, 17 is prevented by time delay circuits comprising members 12,13,14 and 19, 20, 21. A further such circuit comprising members 25, 26, 27 prevents energization of the relay 23 (through the contacts C2) when the "ON" button 4 is actuated. A switch 15 is parallel with the thermostat 11 enables the motors 9, 10 to be operated independently of the relay 2 and other circuit members.

A machine for removing moiles 58 from glass articles 60 where the article is held in a chuck 20 which is reciprocable along the axis of the article, the glass at the proposed zone of separation being heated, when the chuck is moved to present the article to a concentric ring of burners 9, the moile being engaged resiliently by concentric fingers 50, when the chuck is moved to remove the article from the burners, is characterized by the fingers 50 contacting slidably with the moile and article, during the movement of the article towards the burners, in such manner that the fingers are moved radially outwards to permit passage of the article, but are moved yieldingly towards the axis to hold the moile when the article is withdrawn from the burners. The article or the ring of burners are rotatable, and the sequence of operations is (a) the article is moved through the fingers and the separation zone is heated, (b) the article is partly withdrawn to enable the fingers to engage and retain the moile and thus to attenuate the glass at the separation zone, (c) the article is again moved towards the burners which play upon and melt through the attenuated glass, (d) the article is withdrawn entirely from the fingers and is removed for the chuck. In Fig. 1, a vacuum chuck 20 is connected to a vacuum source through the passage 19 in the sliding bar 18, and swivel pipe 21. The bar 18 is given rapid vertical movements by a lazy-tong mechanism 30, the end links being connected to sliders 33 ... 36 on guides 37, 40. The lower sliders 33, 34 have pins which engage cam grooves in a disc 38 rotated by a handle 39. A balance weight 41 is connected by a cable 42 with the upper guide 40 and the downward movement of the bar and chuck is limited by an adjustable stop 45. Each finger 50 is pivoted at 51 on a slider 48 which is adjustable by screw means 56, 57 in the bracket 16. An adjustable counterweight may be provided on each finger 50 so that the tendency is for the finger to swing towards the axis of the article, or, as shown, the finger may be pressed towards the said axis by a spring-plunger 52. The operative part of the finger consists of an insulating or refractory material 54. The burners, which are directed tangentially to the article, are preferably directed slightly upwards so that the flames lick the severed glass edge and produce a final trimming of the edge. In a modification, the vertical movements of the bar 18 are produced by a hand rotated toothed wheel which engages rack teeth on the side of the bar. The chuck is held on the bar 18 by a union-nut which retains a tang on the chuck in the central suction supply bore.
