Title: Control system for industrial heating apparatus
IPC: F23D14/12
Filed: 1962-12-28
Abstract: 1,034,079. Controlling furnace systems; controlling burners. HUPP CORPORATION. Dec. 28, 1962 [Dec. 29, 1961], No. 48770/62. Headings F4B and F4T. Industrial heating apparatus having combustion type infra-red generators has means for automatically changing from a fuel rich starting mixture to a leaner running mixture when the burners are satisfactorily lit. On closure of a manual start switch, a fan is energized to purge the oven, and the satisfactory flow of the purge gases starts a purge timer. At the end of the purge cycle, blowers feeding air to the fuel mixers are started, a motor-operated valve in the fuel supply line start to open, a second ignition timer is energized and a latch relay is energized to start a shut-down timer. The spark igniters are energized and the rich starting mixture supplied to the burners is lit. Satisfactory ignition of the burners allows the de-energization of the timers, latch relay and igniters, and operates the control motors of valves in the fuel premixers to adjust the mixture to a running value. If the burners fail to light, the ignition timer completes its cycle, and since the shut-down timer is still running, the start-up cycle is reinitiated. After one more attempt to light, the shut-down timer will have completed its cycle, and the start-up cycle can only be reinitiated on manual release of the latch relay. If any of the burners fail during operation, the system is shut down, and the start-up cycle is automatically re-initiated. If the burners become overheated, or a conveyer passing through the oven stops, the system is shut down, and the start-up cycle repeated as far as purging the oven. Since the over-heat relays and the conveyer interlock are in series with the ignition timer the cycle cannot proceed. A manual selector switch in the ignition timer circuit enables the lighting of the burners to be delayed until goods are actually entering the oven, and manual selector switches control the setting of the motor-driven valves in the pre-mixers to give high, medium or low heat outputs. Air-flow switches prevent the burners being lit if a satisfactory air flow is not present in the pre-mixers.

Filed: 1967-10-27
Abstract: 1,171,550. Hydraulic reciprocating pumps. E.K. MOORE. Oct.27, 1967, No.48866/67. Heading F1A. A well pumping apparatus, e.g. for oil-gas mixture, comprises a free piston 200 in the well tubing string 20 which is moved upwardly by the well pressure beneath it to lift a slug of oil up the tubing when an outlet valve 38 is opened to release the pressure above the piston, the slug being discharged through a pipe 32 and the plunger averted at the top of its stroke by a pneumatic shock absorber, which acts to close valve 38 for the downward stroke of piston 200 under gravity. Valve 38 is operated cyclically by a timing device 40, 41 incorporating a multi-lobed cam wheel controlling the flapper valve of a pneumatic pilot valve which supplies pneumatic pulses to the actuating diaphragm of valve 38, Figs. 4 and 6 (not shown). The device 40, 41 operates at a rate determined by the well characteristics, the pneumatic shock absorber additionally acting to close valve 38 when the piston reaches the top of its stroke. The shock absorber comprises a piston 50 which is engaged by the piston 200 and moved upwardly to pressurize gas in chamber 35 the gas pressure acting through a needle valve 70 to operate a piston to trigger the closing of valve 38, Fig. 3 (not shown). A spring 66 on piston 50 provides additional shock absorption. A check valve 62 in piston 50 permits its downward stroke. The free piston 200 has a segmental seal 202 which is expanded to seal against the well tubing when the piston strikes the bottom of the tubing, and is retracted, to permit the downward stroke under gravity, when the piston strikes the pneumatic shock absorber piston. The seal comprises segments 204 mounted on a piston portion 210 which is axially movable relative to piston portions 206, 220. The segments 204 are loaded by springs 248 outwardly from the piston and have tapered surfaces 280, 260 co-operating with corresponding tapered surfaces on piston portion 206 and a collar 205, so that relative axial movement between the piston portions causes outward or inward movement of the segments. A spring-loaded ball 256 engages in grooves 252, 254 to hold the segments in their extreme positions.

A resetting control mechanism for apparatus, e.g. a petrol pump having a resettable counting mechanism comprises a sequencing link 140, means actuating the link from its inactive position (as shown) to its active position, Fig. 9 (not shown) after predetermined operation of a resetting element 72, control means operable with the link in its active position for discontinuing the operation of the resetting element and for actuating the apparatus, and manually operable means for returning the link to its inactive position. As illustrated in Fig. 1 (not shown), when the nozzle 12 is removed from its receptacle, a handle (86) is turned clockwise, rotates control shaft 84 and control cam 90 from the OFF to the ON position, thus rocking a lever 104 to actuate a switch 106 and energize a driving motor. The motor drives through gearing and ratchet pawl 130 an intermediate shaft 118 which is connected to a reset drive shaft 72 via gears, thereby resetting the pump register (18) (Figs. 4 and 5, not shown). Link 140 is displaced downwardly by rotation of cam 132 carried by shaft 118, and when the link is fully extended, the ratchet drive is declutched, thereby terminating the drive. Pins 166, 168 on the link extension 164 are received within slots formed respectively in a pump motor operating lever 170 and a valve operating lever 172. With the pump motor operating and valve 177 open, fuel is delivered and the register (18) suitably driven. When the delivery is complete and prior to restoring the nozzle 12 to its receptacle, the handle (86) is turned anticlockwise which rotates cam 90 and withdraws switch operating lever 104 to release switch 106, and subsequently releases the pump operating lever 170 enabling link 140 to return to its inactive position. In a modification, Fig. 10 (not shown) the mechanism provides remote control of the reset as by a single-pole, double-throw switch (220).
