Granted: 1991-10-08
Abstract: SLOPE MOWER                         Abstract A mower vehicle includes a vehicle frame and single front and rear driven wheels.  The vehicle is adapted to conform generally to slopes and the like by maintaining the frame in a generally upright orientation.  First and second blade housings are pivotally connected to the frame and swingable about an axis extending longitudinally of the frame.  The first and second blade housings extend laterally from opposite sides of the frame.  Each blade housing carries a driven cutting blade.  The blade housings are open to one another and have a shared discharge passage at a center rear section thereof.  The blades overlap slightly and rotate in synchronized reverse rotations relative to one another.  Hydraulic cylinder assemblies are provided to actuate the first and second blade housings about the longitudinal axis in response to changes in slope of the surrounding terrain. A leveling system is provided for sensing changes in attitude of the vehicle frame, and for consequently actuating the hydraulic assemblies to maintain the vehicle frame in a generally upright position and the first and second blade housings in operative contact with the ground.

Abstract: METHOD AND DEVICE FOR THE REELING OF WEB                     ABSTRACT OF THE DISCLOSURE          Method and device for the reeling of a web. The web is reeled by supporting an outer circumference of the roll being formed with at least two supporting units. A first such unit in a direction of arrival of the web is a carrier roll provided with a mechanical rotating drive over which the web is passed to reeling. The carrier roll forms a reeling nip supporting the roll from below. A press roll is situated above the roll being formed so that the roll being wound is stably maintained in reeling position. The roll wound about a core in a nip support between the carrier roll, a belt roll, and the upper press roll. When the roll is wound and increased, the reeling continues the nip support by the carrier roll and the upper press roll, and additionally on a belt supporting zone situated as a direct extension of the support zone of the belt roll. The final stages of the reeling are carried out up to a full roll by extending the belt support zone and, at the same time, by adjusting tensioning of the supporting belt or belts so that the linear loads in the various supporting nips of the roll remain within suitable limits in view of progress of reeling and of quality of the roll so being wound.

Abstract: ABSTRACT         A local area print server for connection to a printer to form a printing system for servicing printing requests is disclosed.  The local area print server both controls the servicing of printing requests by the printer, and in response to printer requests for resources needed to satisfy a printing request, either provides required resources, or obtains the resources from a remote component.  The local area print server includes a number of internal modules that, arrange the servicing of printing requests, provide and obtain required printer resources, and respond to commands and queries from digital data processing components regarding the status of the printing system and the processing of printing requests.  The local area print server includes a server job controller for receiving printer requests, printing data, printing instructions and resources required to satisfy printing requests.  A resource manager is provided for receiving resource requests from the printer for resources required to satisfy particular printing requests, and, in response to receiving such requests, forwards the necessary resources to the printer.  The system manager serves as an interface between the printing system and other digital data processing components that generate commands and queries regarding how the system processes printing requests.  There is also a status collector adapted for receiving status block messages internally generated by the printing system containing information regarding the changing state of the system and in response to receiving the messages retransmit same to one or more of the other local area print server internal modules that respond to specific printing system status changes.

Title: Flight arrangement for rotary drum dryers

Granted: 1992-09-22
Abstract: ABSTRACT OF THE DISCLOSURE    A rotatable hollow drum for a dehydrator has an inlet at one end and an outlet at the other end. A longitudinal shaft extends axially from one end of the drum to the other.  A plurality of circumferentially-spaced,  longi-tudinally extending flights are mounted to the inner side of the hollow drum.  A plurality of circumferentially-spaced flights is also mounted to the shaft with each of these flights also extending along the shaft.  The flights on both the drum and shaft uniquely comprise a plurality of tines which may have their ends bent, at progressively increasing angles, for intercepting, turning, separating and enhancing the conveyance of pieces of material being dried in the dehydrator as the pieces travel from one end to the other as the dehydrator rotates.  This action promotes constant  movement  of  the  material  in  the dehydrator to provide uniform drying of individual pieces while reducing the likelihood of blockage caused by the accumulation of pieces.
