Abstract: An autonomous underwater vehicle (AUV) may include a fuel cell charging system including a power generation subsystem having an air breathing subsystem taking intake air from the external atmosphere, a supply of compressed hydrogen in onboard storage tanks, an air-breathing PEMFC receiving the intake air and hydrogen, the PEMFC operable to produce electric energy and generating waste water, a water removal system for discharging the waste water offboard, and the fuel cell charging system having a power storage subsystem including a chargeable battery subsystem to receive electric energy to charge the chargeable battery subsystem. A system manager of an onboard data processing system may be configured to control the fuel cell charging system.

Abstract: An optimizing controller for a straight rod stock processing stirrup bender which provides a production method enabling a combination of bent rod stock profiles in multiple counts to be delivered from each individual infed straight rod stock bar, whereby bent rod stock piece output is optimized through such an output combination so as to most efficiently utilize the available stock from each such infed straight rod stock bar and thereby to consistently minimize the tail piece wastage consistent with the stirrup bender tail piece handling capabilities, also thereby substantially reducing labor and waste and handling costs per ton which are otherwise normally associated with the processing of straight rod stock lengths through a stirrup bender.

Abstract: A straight rod stock processor and method for use thereof which incorporates the employment of a rod stock loader to effect automatic shakeout of a piece of straight rod stock in pulling the same from a pre-load bundle of infeed stock and delivery to a set of secondary rod stock compression rollers interposed between the rod stock loader and a stirrup bender just forward of the stirrup bender head on the infeed side thereof so that essentially the entire length of an infed rod stock piece may be thereby positioned and controlled in delivery to the stirrup bender head for processing thus substantially reducing labor and waste and handling costs per ton which are otherwise normally associated with the processing of straight rod stock lengths through a stirrup bender.

Abstract: A table bender controller employing a computerized display screen with the computer therefor being programmed to take keyed-in entry of customer provided bar shape specifications, whether entered by the machine operator at the machine location or from corresponding specification input data downloaded from a remote location input terminal, which specifications are in terms of a finished dimension of the bent bar profile along with the diameter of the bar to be bent and the bend degrees and directions of bend to produce the required shape, all of which either after key-in or downloading is called up in graphical display on the screen in a visual profile corresponding to that to be bent with appropriate machine and bar set instructions for producing such shape, including bending sequence, dimensions, gage marks, pin sizes and ram location for each of the component bends in the sequence.

Abstract: A separable roller sleeve, and methods of making and installing the same, to be provided as original equipment or alternately provide either a roller conveyor retrofit or replacement roller sleeve installation capability for both powered and idler rollers on the input and output sides of a typical roll conveying machine generally of that type employed in a shear line to accomplish movement of reinforcing rods to and from a cutting station, where the separable roller sleeve is fabricated either in the form of or from a section of resilient thick walled tubular material having an inside diameter slightly larger than that of the outside diameter of the roller to which it is to be installed and cut to the roller length, which tubular material member is then converted to a separable roller sleeve by providing therethrough a longitudinally extending compression closing spiral wall separation from one end thereof to the other whereby the spirally separable roller sleeve thus formed may then be twistably opened manua

Abstract: A fenceliner for inhibiting growth of grass, weeds and other vegetation beneath and closely adjacent a fence so as to make cutting or trimming of such vegetation unnecessary, and for inhibiting passage of small animals across the border defined by the fence. The fenceliner can be provided as a coiled strip of thin flexible material such as plastic or metal. The thin material is uncoiled and rolled out along the length of the fence and is cut to fit around fence posts. Preferably the material is colored to closely simulate the coloring of the surrounding vegetation. A centrally located longitudinal recess in the strip receives the bottom of the fence panels. Symmetric legs extend outwardly and downwardly from the recess to cover the ground closely adjacent to the fence. The legs have sufficient spring tension to bias the recess against the bottom of the fence panels when the fenceliner is in position on the ground beneath the fence.
