Abstract:
A system and method are disclosed that provide a specific volumetric output (e.g., product feed and discharge) of a material. In some implementations, these systems and methods are particularly suited for use with strand-type materials, namely, materials having difficult handling characteristics. For some implementations, a specific pile depth and width of a material is created on a moving belt to provide a specific volumetric output based on the speed of the belt. One or more leveling drums can be used to make the pile depth consistent. Moreover, a weighing system can be provided that is used in combination with the metering mechanism and other components (e.g., a control system) to create a “weight-loss” type weigh feeder.
Abstract:
A mixing apparatus for mixing two fluids immediately following contact with each other is disclosed. The mixing apparatus includes a spring-loaded ball valve separating a first fluid from a second fluid. The ball valve closes as a result of at least spring force. The ball valve opens as a result of hydraulic pressure of one of the fluids operating against the spring force. Mixing is accomplished instantaneously by dispersing one fluid in a thin pattern around the open ball valve into a stream of the other fluid.
Abstract:
The present invention relates to an isolation pad for mounting a supply vessel to a feeding mechanism, and a system containing such a pad. The isolation pad is made of two plates connected by a flexible elastomer gasket. An aperture extends through both plates and the gasket. One plate is mounted to the supply vessel. The other plate is mounted to the feeding mechanism. Consequently, the supply vessel is supported by the elastomeric gasket. Because the gasket is flexible, the supply vessel is resilient and free to vibrate independently with respect to the feeding mechanism.
Abstract:
Disclosed herein is an automatically controlled weigh feeding apparatus including a container prefilled with a substance, a device for discharging the substance from the container at a controllable weight, apparatus for weighing the container and its contents and for producing an electrical signal proportional to that weight, a first amplifier for amplifying the electrical signal, a first analog-digital converter coupled to said first amplifier and a digital computer coupled to said first analog-digital converter for computing the weight of substance remaining in the container. A second amplifier is coupled to said first amplifier and a ramp off-set circuit which is controlled by the digital computer inputs a second signal to the second amplifier means having a controlled stepping output applied as a second input signal to the second amplifier to maintain the output of the second amplifier within a given selected range of amplitude during one time cycle of operation. A second analog-digital converter interposed between the second amplifier and the digital computer. The digital computer is adapted to compute a corrective signal based on the signal received for controlling the discharge of the substance from the container.
Abstract:
This invention relates to a container system, which includes a container having a mounting bracket mounted thereon to carry a first flange-like element, a second flange-like element disposed in spaced parallel relationship with respect to the first flange-like element, a linking member mounted on the second flange-like element, which also carries a third flange-like element mounted thereon, a fourth flange-like element disposed in spaced parallel ralationship with respect to the third flange-like element, a support frame fixedly mounted on the fourth flange-like element, and a plurality of elongated resilient cross-members extending perpendicular to and interconnecting the first and second and the third and fourth flange-like elements, respectively, the cross-sectional area of the cross-members on any plane parallel to their respective flange-like elements collectively being symmetrically disposed about a pivot axis extending perpendicular to their respective flange-like elements.
Abstract:
In an aspect of the present invention, a system and method are provided that detect belt mis-tracking and in response, automatically adjusts. In some implementations, the system and method are implemented in conjunction with a weigh feeder or weigh belt. In other implementations, the system and method are implemented in conjunction with other devices that convey material via one or more belts. The system and method can be implemented by providing one or more sensors that detect belt mis-tracking, a motor for adjusting a belt pulley and one or more controllers that operate the motor in response to signals from the one or more sensors.

Abstract:
Systems and techniques to brew coffee are described. In general, in one implementation, the technique includes: releasing water from at least one water inlet onto ground coffee in a stationary coffee filter. The ground coffee is automatically agitated while the water is being released using an agitator that is connected to an agitator motor to aid flavor-enhancement during the brewing process by helping to assure that the coffee grounds are uniformly mixed, saturated and blended with hot water and to substantially maintain an evenness of depth of the ground coffee. The water, now containing extracted coffee chemicals, is collected in a coffee vessel.
Abstract:
A sweep arm assembly and cleanout port are provided for a dry bulk materials feeding system. A supply hopper having an outlet is disposed above a chamber such that material may flow from the hopper to the chamber. The chamber has a flat bottom surface. A feed trough is disposed below a slot in the bottom surface of the chamber such that material may flow from the chamber to the feed trough. A sweep arm is disposed in the chamber and located adjacent to the bottom surface. The sweep arm is rotated to "sweep" the material in the chamber to the slot in the bottom surface. Further, a method is provided for feeding dry bulk materials. Material to be fed is loaded into a supply hopper. Material is permitted to flow from the supply hopper into a chamber, which chamber has a flat bottom surface. Material in the chamber is swept into the feed trough. The material is swept into the feed trough by a sweep arm that is rotated in the chamber adjacent to the bottom surface of the chamber. The material in the feed trough then is fed into a process at a controlled feed rate.
