A method and apparatus for extracting juice from a previously de-juiced fruit mass which as been pressed within a primary press, the previously de-juiced fruit mass being discharged from the primary press and then being broken-up and mixed externally of the primary press, and then pressed again preferably by using a secondary thin layer repressing press which permits the repressed press cake to be quickly and easily loaded and emptied.

A particulate residue separator and a method for separating a particulate residue stream may include an air plenum borne by a harvesting device, and have a first, intake end and a second, exhaust end; first and second particulate residue air streams that are formed by the harvesting device and that travel, at least in part, along the air plenum and in a direction of the second, exhaust end; and a baffle assembly that is located in partially occluding relation relative to the air plenum and that substantially separates the first and second particulate residue air streams.
摘要:
A method and apparatus for selectively harvesting multiple components of a plant material. A grain component is separated from the plant material such as by processing the plant material through a primary threshing and separating mechanism. At least one additional component of the plant material is selectively harvested such as by subjecting the plant material to a secondary threshing and separating mechanism. For example, the stems of a plant material may be broken at a location adjacent one or more nodes thereof with the nodes and the internodal stem portions being subsequently separated for harvesting. The at least one additional component (e.g., the internodal stems) may then be consolidated and packaged for subsequent use or processing. The harvesting of the grain and of the at least one additional component may occur within a single harvesting machine, for example, during a single pass over a crop field.

A real-time multi-tasking digital control system with rapid recovery capability is disclosed. The control system includes a plurality of computing units comprising a plurality of redundant processing units, with each of the processing units configured to generate one or more redundant control commands. One or more internal monitors are employed for detecting data errors in the control commands. One or more recovery triggers are provided for initiating rapid recovery of a processing unit if data errors are detected. The control system also includes a plurality of actuator control units each in operative communication with the computing units. The actuator control units are configured to initiate a rapid recovery if data errors are detected in one or more of the processing units. A plurality of smart actuators communicates with the actuator control units, and a plurality of redundant sensors communicates with the computing units.

A high speed microfilm searching system is disclosed. The system optically displays frames of the microfilm. A frame or column of microfilm is made up of a sensor mark, pages of information and an index code. The index code is a meaningful alphanumeric or numeric key that accompanies each page or column. If it is alphabetic it varies in strict alphabetic sequence. If the components of the key are numeric they vary in an increasing or decreasing order. Microfilm projecting means mounted in the filmpath between feed and take-up reels clearly display on a viewing screen a page of information when the microfilm is stationary in accordance with existing technology. The high speed search system is new technology. A strobe lamp displays indexes of the moving microfilm on a screen. Each of the frames having an index of digital form and also has an optically detectable marker. The marker is placed in a fixed position with respect to the digit positions of the index to insure accurate strobing without the need for masks or shutters. Electronic control means is optically responsive to each marker to generate a marker signal which can trigger the strobe and display the index of that page, like a movie picture. At very low microfilm retrieval speeds each character of the index is legible so that all of the characters of the index can be read by the user. At increasingly high retrieval speeds only more significant characters can be read because of the rapid change of the low order characters. At the increasingly higher speeds the electronic control means may be only responsive to every second, third, fourth, etc. marker signal. As the desired index comes into range, whether going forward or backward, the viewer operator slows the speed of the microfilm so that more of the characters of the index can be read. When the desired index is very close, the film is moved very slowly so that all of the characters of each index can be read. This film is then stopped on the desired frame so that the contents of the page can be read on the viewing screen.
摘要:
A method and system for redundancy management is provided for a distributed and recoverable digital control system. The method uses unique redundancy management techniques to achieve recovery and restoration of redundant elements to full operation in an asynchronous environment. The system includes a first computing unit comprising a pair of redundant computational lanes for generating redundant control commands. One or more internal monitors detect data errors in the control commands, and provide a recovery trigger to the first computing unit. A second redundant computing unit provides the same features as the first computing unit. A first actuator control unit is configured to provide blending and monitoring of the control commands from the first and second computing units, and to provide a recovery trigger to each of the first and second computing units. A second actuator control unit provides the same features as the first actuator control unit.

A monitoring system and methods are provided for a distributed and recoverable digital control system. The monitoring system generally comprises two independent monitoring planes within the control system. The first monitoring plane is internal to the computing units in the control system, and the second monitoring plane is external to the computing units. The internal first monitoring plane includes two in-line monitors. The first internal monitor is a self-checking, lock-step-processing monitor with integrated rapid recovery capability. The second internal monitor includes one or more reasonableness monitors, which compare actual effector position with commanded effector position. The external second monitor plane includes two monitors. The first external monitor includes a pre-recovery computing monitor, and the second external monitor includes a post recovery computing monitor. Various methods for implementing the monitoring functions are also disclosed.
