Other supporting apparatus, which are inputs and outputs of the controller, include a rotary encoder to measure the degrees of revolution of the pump, an air solenoid valve to apply air (motive force) to the stepping motor and an on/off switch to start and stop the depositing operation. Each nozzle on the depositing manifold has a flow control device to equalize the flow and therefore each cup weight of product deposited into the baking pan. A feed tank or hopper supplies a constant flow of product to the suction of the depositor pump. The manifold is typically mounted a few inches above a conveyor which carries baking pans underneath the manifold nozzles.

  • Patent number: 5456298
    Abstract: A device for providing a measured portion of food product on demand in which a portioned metering head has an inlet to receive the food product under pressure and an outlet to discharge the food product onto the food-receiving medium. There is a disk in the housing which has a disk passageway connecting the inlet and outlet passageways of the metering head. Within the disk passageway is a piston which can slide from one end to the other. By rotating the disk, the food product pushes against the piston causing it to push the food product previously within the disk passageway out into the outlet passageway of the metering head. The cycle repeats with the disk rotating 180.degree., once again positioning the piston adjacent to the inlet passageway. A photoelectric eye signals a control mechanism and connected air cylinder to rotate the disk each time a food-receiving medium is disposed under the metering head.

    Abstract: An automatic water replenishing system is designed for use with multiple dye vats used for tinting eyeglass lenses, but the broad principles of the invention could apply to other systems used for replenishing individual ones of plural vats or reservoirs with water or some other liquid. A rotary water distributor rotates about an arc when it is signaled by water level sensors that the water in a particular vat is low. As the rotary distributor reaches the low reservoir, the LED carried by the distributor actuates a photo transistor adjacent the particular reservoir that needs replenishing, causing the motor to stop and the water supply solenoid valve to be actuated, filling the reservoir until a brief period of time after the level sensor indicates a full condition to the central control system.
