Title: Method and apparatus of installing a whipstock
Inventor: LEMBCKE JEFFREY
IPC: E21B23/01
Filed: 1996-05-30
Abstract: A one-trip system for milling a window using a whipstock is disclosed. The whipstock (10) can be set on a packer or anchor which can be an electric linetype packer (P) which, without modifications, can be set with the hydraulic mechanism disclosed so as to avoid the need for running a wireline rig. The assembly of the packer or anchor and whipstock is run into the wellbore in a single trip, with a mill or mills capable of milling a window. At the conclusion of the milling, the mill or mills (18) are retrieved. Thereafter, a retrieving tool is attached to the whipstock and facilitates a release of the setting tool from the packer so that the setting tool and the whipstock are retrieved together. This leaves a seal bore (114) within the packer which can be employed with a subsequent tubing string run through the packer to that production can be obtained through the packer as well as through the deviated wellbore while potential leakpaths in the packer from the annulus to the tubing are eliminated by the withdrawal of the setting assembly.

IPC: B05B3/06
Filed: 1997-07-03
Abstract: A discharge jet assembly for spas including a rear wall fitting, an orifice cap closing the rear wall fitting, and a jet body rotatably mounted within the wall fitting. The rear wall fitting includes a cylindrical central cavity and a vertically disposed air orifice opening into the central cavity. A rear portion of the jet body defines a cylindrical mixing chamber fed by a horizontal cylindrical water inlet and by an air inlet channel formed in the outer circumference of the jet body. The air inlet channel is positioned so as to rotate into and out of communication with the air orifice of the rear wall fitting. The jet body further includes means for interacting with a stop on the orifice cap so as to appropriately limit rotation of the jet body air inlet channel with respect to the air orifice. An arced continuous seal containment groove and integrally mounted seal surrounds the air inlet channel so as to provide an airtight seal between the rear wall fitting and the jet body. Male retainer elements employing rearward-facing split projections which plug into complementary openings in a female retainer element facilitate mounting of various nozzle styles within the jet assembly. Axial flutes formed in a barrel portion of an eyeball nozzle component provide a flow rate enhancing feature.

Title: A pre-loading device for a radial-bearing unit
Inventor: ARVIDSSON THOMAS NILS
IPC: F16C35/06
Filed: 1996-03-13
Abstract: Axially spaced radial bearing units (30, 50) for a shaft assembly are pre-loaded by hydraulic pressure. Each of the bearing units is mounted to an axially displaceable seat (40, 60). The pre-loading pressure between the two bearing units (30, 50) is maintained at a constant pre-loading pressure by a hydraulic pressure which is exerted in chambers (44, 64) partially defined by the seats. A pressure accumulator (70) supplies pressure to the chambers (44, 64) so that a constant pre-loading pressure may be applied to the radial bearing units (30, 50) while allowing for axial displacement of the bearing units and the shaft (12).

Title: Method of printing on linerless labels
Inventor: CHEN XIN
IPC: B41M5/26
Filed: 1996-06-06
Abstract: A method of printing on a release layer of linerless label material including the step of advancing linerless label material and a thermal transfer ribbon coated with ink through a thermal printer. The ribbon is moved over a heated transfer element of the printer. The heated transfer element is located on an edge or on a corner of an edge of the thermal printer. The ribbon is then heated to cause the ink to reach a molten or fluid state. The ink transfers in its molten or fluid state to the release layer of the linerless label material. Certain wax/resin and resin based thermal transfer ribbons and silicone release coatings have been found to be particularly effective for increasing the ink transfer and anchorage during corner edge and true edge printing on linerless label material.
