Abstract: In one example, a method for an inkjet web printer includes a print engine printing a first print job on a moving first web, a printer controller receiving a second print job, the printer controller determining that the second print job may be printed after the first print job on a second web automatically spliced to the moving first web, a web supply automatically splicing the second web to the moving first web, the printer controller reconfiguring the print engine from a first configuration for the first print job to a second configuration for the second print job without stopping the moving first web or the moving second web, and the print engine printing the second print job on the moving second web.

Abstract: In one example, an inkjet web printer includes a print engine and a controller programmed to determine that a second print job following a first print job may be printed without stopping the web and, without stopping the web, cause the print engine to print the second print job.

Abstract: A technique includes in a machine, processing data indicative of a document to be printed by a printer and which may contain magnetic ink character recognition (MICR) characters to determine whether the data indicates any MICR characters. The technique includes comparing a result of the determination to an intent indicated by a job ticket associated with the document; and controlling the printing of the document by the printer, including selectively performing corrective action in response to the comparison.

Abstract: A method for applying a bonding agent for supplemental ink includes, with a control system of a printing apparatus, determining regions of an image corresponding to regions where a supplemental ink is to be printed, and with the control system, adding an amount of pixels of a standard color channel to portions of a bitmap representing the image, the portions corresponding to the regions where the supplemental ink is to be printed. The amount of pixels is sufficient to trigger application of a bonding agent at the regions.

Abstract: A new joint compensator and systems with it and methods of their use have been invented which, in one aspect, includes a compensator system for compensating for the weight of at least one joint, which is a wellbore tubular member, the compensating system for use below a wellbore apparatus, the wellbore apparatus for supporting the at least one joint, the compensation system having a joint compensator suspended below the wellbore apparatus and connected thereto for selectively compensating for the weight of the at least one joint, a lower elevator suspended below and interconnected with the joint compensator for releasably holding the at least one joint, and a wellbore elevator connected to the wellbore apparatus for selectively supporting the joint compensator and the at least one joint.

Abstract: New joint compensator and systems and methods of their use have been invented which, in one aspect are useful for compensating for the weight of a first joint and at least one subsequent joint, the first joint to be supported above the at least one subsequent joint, the joint compensator in one aspect having a body interconnectible between the first joint and moving apparatus, the body including supporting apparatus for supporting the first joint above the at least one subsequent joints and for providing support of the first joint as it moves with respect to the at least one subsequent joint, the supporting apparatus compensating for weight of the first joint as it moves, the support apparatus for alternately supporting the first joint and then the at least one subsequent joint, the support apparatus initially adjustable to compensate for the weight of the first joint so that the support apparatus is also thereby adjusted to compensate for weight of the at least one subsequent joint.

Abstract: A new tool has been developed for, in one aspect, facilitating release of a tubular string coupled between a travelling block and elevators with insufficient clearance to release elevator slips in order to remove the tubular. In one aspect the releasing tool is effectively shortened permitting release of the elevators. Such shortening is effected by releasing an expansion sub and piston within the tool for relative movement with respect to other parts of the tool. Initially the expansion sub and piston are held in place by fluid in a first chamber. Movement of fluid from the first chamber and movement of fluid into a second chamber housing the piston results in piston movement (and movement of the expansion sub which is secured to the piston) to effectively shorten the tool. In one aspect the fluid moves in a closed loop between the chambers and no fluid is expelled to the environment. In another aspect only one fluid chamber is used.

Abstract: A tong, preferably a power tong, with one or more floating jaws which are releasably retained on and selectively movable with a rotary device; in one aspect the jaws having a compound jaw camming surface with a primary cam action surface, a rest surface, and a fixed positioning surface; and in one aspect such a tong with a releasably jaw urging system for releasably urging the jaws against camming jaw rollers.
