Abstract: Molding material consisting of resin coated reinforcing fibers in a molten mass of resin and fibers is prepared at a molding site for controlled supply to a molding machine. A conveying device, such as a pair of pinch rollers, serves to pull fibers from supply spools through guide orifices of a coating die having a chamber within which the fiber is coated with molten resin. Further impregnation of the fibers with resin takes place in the conveying device, which also develops pressure on its output side serving to push the mass of hot resin and fiber into a receiving device for movement to a molding machine. The receiving device may be the feed screw for an injection molding machine or simply a plate movable to and from a compression molding machine. The fibers may be cut into predetermined lengths by a cutting device positioned downstream of the aforesaid conveying device.

Abstract: An aerator for mixing an ambient gas with a liquid and agitating the liquid incorporates at least three bearings that are rigidly connected to an aerator housing. A propeller is driven by a central shaft that is rotatably mounted in the aerator housing using the bearings. Two bearings are located near the ends of the central shaft. At least one additional bearing is located between the ends, for example, in a intermediate position. This additional bearing may absorb some of the force that would otherwise be transferred to the bearing near the propeller end of the central shaft. The bearings are thus subjected to lower stress and may exhibit a prolonged useful lifespan.

Abstract: A control system for a grain harvester. The control system monitors the output of a grain sensor and uses the monitored value to actuate one or more relays having different energization levels. As each relay is actuated it completes a circuit, which is used to modify power that is fed into a control mechanism and which is used to control an operational parameter of the harvester. Depending upon the monitored value of the sensor, the control system will modify the power that supplies a control mechanism that is used to control an operational parameter of the harvester, such as the groundspeed. If the output from the sensor is less that a predetermined threshold, the harvester will operate normally. If the output of the sensor is above a first threshold, the control system will modify the supply voltage. If the output of the sensor is greater than a second threshold, the control system will modify the supply voltage accordingly, and so forth.

Abstract: A method of determining an average length of reinforcing fiber in a sample of reinforcing fibers is disclosed. A sample of reinforcing fibers is weighed to obtain a total sample weight. The sample of reinforcing fibers is placed in a fiber separating mechanism and suspended in water. The water is stirred after which the water is allowed to settle such that the sample of reinforcing fiber divides into a plurality of fractions in separate sections of the fiber separating mechanism. Each fraction has reinforcing fibers of substantially similar lengths and is separately weighed. An average fiber length is calculated from the relative weights of each of the plurality of fractions and the total sample weight. In addition, a method of determining an average length of a reinforcing fiber in a composite material having a resin and a plurality of reinforcing fibers is disclosed.
