Abstract: A method for drilling riserless that includes providing a drilling fluid to a drilling assembly for drilling a borehole on a seafloor, the drilling assembly comprising a drill string and a bottomhole assembly, and wherein the drilling fluid includes a brine, and a non-hydratable clay, wherein the drilling fluid is substantially free of hydrating clays, and flowing the drilling fluid and cuttings through an annulus formed by the drill string and the borehole into sea water is disclosed.

Abstract: An apparatus for practice and demonstrating defense arts, such as karate, includes a vertical wall-mounted main frame unit assembled of a pair of vertical, symmetrical, cylinder shaped tubes secured to three horizontally extending wall mounting brackets or to a free standing frame unit. The purpose of the invention is to support a height adjustable hanging target, such as a speed bag or heavy bag, which the artisan strikes with various human appendages, such as the hand or foot and other certain appropriate weapons. The hanging target is supported by a striking bag carriage assembly and a striking bag platform as it rides along the vertical tubing.

Abstract: Ink jet printing apparatus of the type having a carriage that traverses a printing zone with a plurality of insertable print/cartridges includes a system for use in coordinating the transverse printing of such print/cartridges to compensate for variable transverse print/cartridge locations. The system employs an electrooptical scanner located along the transverse path of the carriage for signalling the passage of a print/cartridge feature(s) that are indicative precisely of an instantaneous horizontal position, vis-a-vis the scanner, of the orifice array of a passing print/cartridge; a carriage detector for periodically sensing and signalling the successive instantaneous positions of the carriage during its traversing movement; and means, responsive to signal inputs from the scanner and the carriage detector, for computing and storing horizontal location data for each print/cartridge orifice array.

Abstract: Ink jet printer for printing along a linear print zone with a plurality of insertable print/cartridges employs a carriage for traversing the print zone and supporting the print/cartridges with their orifice arrays mutually indexed to a carriage reference that is parallel to the direction of carriage traverse; detecting and storing the relative transverse locations of the indexed orifice arrays; and controlling the actuations of the supported print/cartridges in accordance with their detected transverse locations. A detecting and storing sub-system detects and stores inter-array spacings in the form of encoder mark-count plus intra-mark phase information. A control sub-system: (1) outputs printing information signals for the print/cartridges on the basis of the stored mark-count information; and (2) enables print/cartridge actuations in sequential orders based on the stored intra-mark phase information. These orders differ in forward and retrace printing.
