Title: Nonholonomic robot field coverage method
Inventor: BARBOI MICKEY
IPC: G05D1/02
Filed: 2020-04-13
Abstract: A software product and methods determine a field coverage method for a nonholonomic robot (102) to process a field (180) using parallel lanes (850, 1350). A cellular decomposition algorithm divides the field into a plurality of cells (1432, 2132), each having a plurality of parallel lanes (850, 1350). Permutations of lane processing orders are determined for each cell (1432, 2132), based upon a minimum turning radius of the robot (102). A cell graph (2100) is generated to determine a shortest path for single-time processing each lane in each cell (1432, 2132) without violating the minimum turning radius of the robot. A step list (368) defining movement of the nonholonomic robot (102) along each lane (850, 1350) in each cell (1432, 2132) of the shortest path through the cell graph is generated, and a path program (122) to control the nonholonomic robot (102) to process the field (180) is generated based upon the step list (368).

Abstract: In a rolling mill wherein hot rolled rod is directed along a downwardly curved path into a vertical laying head which forms the rod into a series of rings, a method of and apparatus for propelling the rod through the laying head. The rod is passed between a pair of adjustable driven pinch rolls located in advance of the downwardly curved path. An initial closing force is exerted on the pinch rolls to establish an initial parting prior to entry of a rod front end therebetween. The initial parting is sized to produce at least some rod deformation while providing a driving relationship between the pinch rolls and the rod. The initial closing force is greater than the momentary surge in separating force accompanying impact of a rod front end with the pinch rolls. The initial parting is maintained until the rod front end has negotiated the downwardly curved path and has passed through the laying head, at which time the initial closing force is released. The pinch rolls can then either be opened completely to allow the rod to continue running freely therebetween, or the initial closing force can be replaced by a lower secondary closing force which allows the rod to push the pinch rolls apart to a secondary parting. The secondary parting continues the driving relationship between the pinch rolls and the rod, without any accompanying rod deformation.

Compared to conventional high silicon spheroidal graphite cast irons, this cast iron distinctly higher in the resistance to oxidation at high temperatures and is higher in strength too. This cast iron is far lower in production cost than conventional high nickel spheroidal graphite cast irons which are high in the resistance to oxidation at high temperatures. 
     Preferably the cast iron contains at least 1.7 wt% of C and from 0.25 to 0.7 wt% of Cr. Suitable spherodizing agents are Mg, Ca and Ce. 
     The cast iron may be made by a conventional process by allowing a molten metal of an appropriate composition and containing a spheroidizing agent to solidify in a mould and then subjecting the solidified casts to a spheroidizing- ferritiiing heat treatment.

Abstract: @ A character generator for a raster printer which prints in the page mode. Input format data is generated in response to the input print data which defines for each pattern the position of the pattern on the page, the size of the pattern and the location of the pattern in the raster pattern storage. The format data is accessed for all patterns beginning with a predetermined plurality of scan lines and raster data is accessed in response to the format data to store in an output buffer the raster pattern data in the sequence, size and position defined by the format data. The raster pattern data can then be accessed to control a printer to print on a print medium a pattern defined by the input print data. 
     As shown in the drawing print data is received by channel adapter 14 from the host system channel 10 and is passed to control means 16. The control means includes a microprocessor 24 which processes the received print data and supplies pattern control data to the character generator 32. The pattern control data is entered in storage 34 and is transferred therefrom to pattern shifter 36 under the control of pattern generator 35. Pattern shifter 36 properly positions the data in partial page buffer 38. The data is then gated from the buffer 38 to serializer 39 which supplies the data serial to the raster printer.
