Title: Engine speed control for hoist and tongs
Inventor: NEWMAN FREDERIC M
IPC: B66D1/18
Filed: 2001-10-26
Abstract: A mobile service rig for servicing an oil well includes a variable speed engine and a multi-speed transmission that selectively powers a drive wheel for transport, a hoist for lifting and lowering well-related components, and a hydraulic circuit for a tong used in tightening and loosening sucker rods or tubing. A speed adjuster operatively coupled to the engine limits the speed of the engine when the tong is operating, while a flow restriction limits the rate of hydraulic fluid flowing through the tong. Such an arrangement reduces power consumption, reduces heat, and avoids over tightening a sucker rod connection.

Title: Therapeutic compounds comprised of anti-fc receptor binding agents
Inventor: GRAZIANO ROBERT
IPC: C07K19/00
Filed: 2000-07-25
Abstract: Multispecific molecules which induce effector cell-mediated killing of target cells are disclosed. The molecules are "multispecific" because they bind to multiple (two or more), distinct targets, one of which is an Fc receptor on the surface of an immune cell. Multispecific molecules of the invention include molecules comprised of at least one portion which binds to an Fc receptor, such as an Fc.gamma. receptor (e.g., Fc.gamma.RI) or an Fc.alpha.  receptor, and at least one other portion which binds to a different target, such as an antigen on a tumor cell or a pathogen. Multispecific molecules of the invention also include antigen "multimer complexes" comprised of multiple (i.e., two or more) portions which bind to a molecule on an antigen presenting cell (APC), such as an Fc receptor, linked to one or more antigens. These multimer complexes target antigens, such as self-antigens, to APCs to induce and/or enhance internalization (endocytosis), processing and/or presentation of the antigen by the APC. Therefore, these molecules can be used to induce or enhance an immune response either in vivo or in vitro against a normally non-immunogenic protein, such as a self-antigen. In a particular embodiment, at least one portion of the multispecific molecules comprises a humanized or human antibody or antibody fragment (e.g., ScFv or Fab') which binds to an Fc receptor or a receptor on a target cell (e.g., EGF-R or HER2).

Title: Well reference apparatus and method
Inventor: XU WEI
IPC: E21B47/04
Filed: 2002-05-10
Abstract: The reference member provides a permanent reference for the depth and orientation of all well operations and includes a body with an engaging surface for an attaching engagement to the interior surface of an existing casing in a borehole and an orienting surface for orienting well tools within the cased borehole. No sealing engagement is required with the casing.

Inventor: BUCKMAN WILLIAM G SR
IPC: E21B7/18
Filed: 2002-06-12
Abstract: Nozzle jet drill bits for drilling drainholes from a wellbore are provided in a 4 1/2-inch or larger casing. The drills are small enough to allow use of a bit diverter to turn the bits about 90 degrees in the casing when attached to an elastomeric high-pressure tube. Pumping of fluid, which may contain abrasive particles, through the bits allows drilling though the wall of casing, if present, and continued drilling into a formation surrounding the well without withdrawing the bit from the well. Direction-indicating instruments and geophones may be used to measure or monitor direction and location of the bit.  One type of jet drill that may be used can change direction of drilling by controlling pressure at the bit.
