Matthews International had three patents in batteries during Q3 2023. The first patent is for a system that provides powder using a powder hopper, sensors, a feeder hopper, and a processor. The sensors determine the characteristics of the powder in the hopper, and the processor controls the feeder hopper to provide powder when the characteristics are below a threshold.
The second patent is for a system that electrically heats and cools rollers. The rollers have electrical heating elements and air channels, and they are connected to a power source and control circuit through an electrical contact. The control circuit also receives input from temperature sensors. GlobalData’s report on Matthews International gives a 360-degreee view of the company including its patenting strategy.

The patent filed by Matthews International Corp. describes systems and methods for providing powder. The system includes a powder hopper, one or more sensors, a feeder hopper, and a processor. The powder hopper is responsible for providing powder to a pair of rollers. The sensors are used to determine a characteristic of the powder in the powder hopper, such as its height or weight. The feeder hopper is designed to supply powder to the powder hopper. The processor is responsible for causing the feeder hopper to provide powder to the powder hopper when the characteristic of the powder in the powder hopper falls below a certain threshold.
The patent includes several claims that further specify the system and method. Claim 1 describes the system, including a first powder hopper, one or more first sensors, a first feeder hopper, and a processor. The processor is configured to cause the first feeder hopper to provide powder to the first powder hopper when the characteristic of the powder in the first powder hopper is below a first threshold. Claim 2 specifies that the first powder hopper is positioned adjacent to the first pair of rollers.
Claims 3 and 4 describe different types of sensors that can be used in the system. Claim 3 states that the first sensors can be level sensors, which determine the height of the powder in the powder hopper. Claim 4 states that the first sensors can be weight sensors, which determine the weight of the powder in the powder hopper.
Claims 5 to 8 introduce a second powder hopper, second sensors, and a second feeder hopper to the system. The processor is configured to cause the second feeder hopper to provide powder to the second powder hopper when the characteristic of the powder in the second powder hopper is below a second threshold. Claims 9 and 10 specify that the first and second powders can be the same or different.
Claims 11 to 19 describe the method of providing powder. The method involves providing powder from a powder hopper to a pair of rollers, determining the characteristic of the powder in the powder hopper using sensors, and delivering powder from a feeder hopper to the powder hopper when the characteristic of the powder falls below a threshold. The method can be applied to both the first and second powder hoppers.
In summary, the patent describes a system and method for providing powder using hoppers, sensors, feeders, and a processor. The system ensures that the powder hopper is always supplied with powder by monitoring its characteristic and initiating the delivery of powder from the feeder hopper when necessary.
