The flow sensor includes a light emitter and a light detector, which may be disposed adjacent the liquid outlet of the spray device and oriented such that a light beam projected by the light emitter is aimed at the spray generated by the spray device and reflected by the spray into the light detector.

Abstract: A pair of hoses connects directly from the feed pumps to the extruder without utilizing a PCV (pressure compensating valve). Each feed unit has automatic air pressure relief through a solenoid valve on top of the feed unit so that the unit does not stall at full static line pressure. When the dispense valve at the extruder is shut off, air pressure to the air motor is dumped. A pair of electric eyes is utilized—the first signals the pump (by providing pressurized air) to provide pressure while the second actually opens the extruder when the article to be coated comes into position. The first valve is located only a short distance ahead of the second valve so that the line pressure does not have a chance to exceed the dynamic pressure before the extruder opens.

Abstract: Systems and methods are disclosed for an automatic and continuous supply of coating material to a coating applicator in optical fiber fabrication. The present invention switches from one coating reservoir to another by way of a transitional period in which both coating reservoirs are supplying coating material to the coating applicator. For example, while an in-use reservoir is supplying the coating material to the coating applicator, a standby reservoir is being filled, settled to off gas air bubbles and then slowly pressurized. A sized orifice is used to slowly bleed off pressure from the in-use reservoir at a rate that does not allow the pressure in the in-use reservoir from falling out of a desired pressure range.

While the photoresist is supplied into the trap tank, the photoresist-blocking valve is opened to release air. After the photoresist supply into the trap tank is completed, the photoresist-blocking valve is closed to prevent the loss of a large amount of the photoresist through the drain line.

Abstract: A photoresist spraying apparatus for coating a photoresist with pressure from a nitrogen gas includes a tank which has a photoresist holding portion and an air portion. A photoresist inflow conduit is connected to a sidewall of the tank to intake photoresist and a photoresist outflow conduit is connected to a bottom of the tank for discharging photoresist. A T-shaped gas conduit has a gas inlet, a gas outlet and a connecting portion therebetween for connecting to the tank. The flow of a gas from the gas inlet to the gas outlet lowers the air pressure inside the tank so that air and bubbles remaining inside the tank are discharged to the gas outlet via the connecting portion, while a photoresist flows into the tank via the photoresist inflow conduit. A valve, provided in the gas outlet of the gas conduit, opens and closes to fill and discharge photoresist in the tank according to the pressure inside the tank.

The computer is programmed to receive inputs from operator controlled panel switches which can be set to select the number of nozzles in the row; an excursion time during which all nozzles in a row spray and a pulse time during which one nozzle sprays. The computer limits the nozzle pulse time to dwell time equal to the quotient of the number of nozzles and the pulse time. The nozzles are automatically cleaned out by compressed air if the supply of fruit to the conveyor is interrupted for a predetermined period of time.

Abstract: A developing unit comprises a guide vane mounted on a portion of the housing which defines a developing opening and disposed for contact with the free end of a developer brush which is formed by a conveying magnetic pole, and a vent formed in the housing at a location removed from the opening. The guide vane cooperates with the brush which moves during the rotation of a non-magnetic sleeve to provide an air pump action, which draws the air containing the toner in suspension into the closed housing of the developing unit from the region of the opening while the vent acts to reduce the internal air pressure within the housing which tends to increase as a result of the air pump action.
