    Abstract: We have found that foam generated from an aqueous medium can have a thermal insulating effect. The creation of a substantial volume of foam on the surface of an aqueous medium can reduce the apparent thermal IR emission substantially when compared to that of the aqueous medium free of foam. This difference in infrared emission can be used to control the addition of a defoaming agent to control foam in the aqueous medium. In the foam control method of the invention, an infrared detector is used to measure the infrared emission of an aqueous medium free of foam and during operations such a measurement is compared to the infrared emission of the aqueous medium under foaming conditions. As foam develops on the surface of the aqueous medium, the apparent thermal infrared emission from the foam is less than that of the aqueous medium free of foam. As the thermal IR emissions drop as foam develops, the difference between the apparent temperature of the foam and the aqueous medium, as measured as infrared thermal emissions, drops. Such a drop in temperature can be used to trigger the addition of a defoaming agent which can substantially reduce foam volume. As the foam volume is reduced, the thermal infrared emission of the aqueous medium returns to a value near the thermal inverting emission of the aqueous medium without foam. At this point, the addition of a defoaming composition is substantially reduced or stopped. During the control method, a predetermined limit is established at which the defoaming composition is introduced into the aqueous medium. As long as the thermal infrared emission of the foamed aqueous medium is different than the thermal infrared emission of the aqueous medium without foam, the defoaming agent is continually added to the aqueous medium. Further, the method permits the amount of defoaming agent added to the aqueous medium to be in proportion to the difference in infrared emission above the preset predetermined limit.

    Abstract translation: 我们已经发现，由水介质产生的泡沫可以具有隔热效果。 在与水性介质的表面上相当量的泡沫的产生可以相对于不含泡沫的水性介质的情况，可以显着降低表观的热IR辐射。 红外发射的这种差异可用于控制在水介质中添加消泡剂以控制泡沫。 在本发明的泡沫控制方法中，使用红外检测器来测量不含泡沫的水性介质的红外发射，并且在操作过程中将这种测量与在发泡条件下水性介质的红外发射进行比较。 由于在水性介质的表面上产生泡沫，所以来自泡沫体的表观热红外发射量小于不含泡沫的水性介质。 随着泡沫发展时的热IR辐射下降，泡沫表面温度与水性介质之间的差异（以红外热辐射测量）下降。 这样的温度降低可以用来引发添加消泡剂，其可以显着地减少泡沫体积。 当泡沫体积减小时，水性介质的热红外发射返回到没有泡沫的水介质的热反转发射附近的值。 此时，消泡组合物的添加显着减少或停止。 在控制方法中，建立了将消泡组合物引入含水介质中的预定极限。 只要发泡水性介质的热红外发射不同于没有泡沫的水性介质的热红外发射，则将消泡剂连续添加到水性介质中。 此外，该方法允许添加到水性介质中的消泡剂的量与预定的预定极限以上的红外发射的差异成比例。

    Abstract: A method for automatically cleaning and lubricating conveyor belt systems is disclosed. A microprocessor controlled control unit (205) senses the movement of the conveyor belt (120) and the presence of items, for example bottles (50), on the conveyor. The control units initiates the application of lubricant, detergent and rinse water onto the conveyor according to the speed of the conveyor, the presence of items and the time passed since the previous application. If the conveyor is stationary, that is, is not in motion, no lubricant or cleaning solution is applied. If the conveyor is moving but no items are on the belt, a reduced amount of lubricant is despensed onto the conveyor system. The conveyor cleaning and lubricating process may be carried out during normal production operations.
