Title: Method and apparatus for determining the type of an object in a distributed object system
Inventor: VANDERBILT PETER
IPC: G06F13/00
Filed: 1996-03-13
Abstract: A method of checking the type of an object located on a remote computer in a distributed object environment computing system is disclosed.  Initially, a type checking method to determine whether a remotely located object is of a specified type is invoked. In the invocation, a target interface identifier is included as an argument. A determination is then made as to whether the target interface identifier is equal to or a base for an apparent interface identifier held by a proxy object located on the first computer.  If the target interface identifier is determined to be equal to or a base for the apparent interface identifier, an affirmative indication to that effect is returned to the client process.  If not, then the target interface identifier is then compared to a real interface identifier. In many embodiments, a call to the server host will have to be made in order to determine the real interface identifier.  In some embodiments, a local cache memory can also be provided to store the results of such inquiries.  The target interface identifier is then compared to the real interface identifier and a determination is made as to whether the target interface identifier is equal to or a base for the real interface identifier.  The result is then returned to the client process.  A method of checking the type of an object and additionally returning an output proxy object is also disclosed.  The output proxy object may be the original input proxy object that has been widened to the class associated with the target interface identifier, or may be a newly created proxy object that is of the same kind as the input proxy and of the same type as the target interface identifier.

IPC: C12Q1/6897
Filed: 1995-05-15
Abstract: This invention provides a method for screening for agents useful for treatment of diseases and pathological conditions affected by cytokines. These agents interact directly or indirectly with an intracellular receptor, which in turn modulates the binding of a rel-like protein, a rel-like protein complex, or other transcriptional proteins to a rel site on the promoter of a cytokine gene. The intracellular receptor can be the estrogen receptor, retinoid acid receptors, retinoid X receptors, glucocorticoid receptor, progesterone receptors, androgen receptor, thyroid hormone receptors, or vitamin D receptor. The select agents can be used to treat osteoporosis, rheumatoid arthritis, inflammation, psoriasis, Kaposi's sarcoma, septic shock and multiple myeloma.

Patent CA-2193519-A1 (CA)
Title: Downhole swivel
Inventor: MILLS ROBERT A R
IPC: E21B43/12
Filed: 1996-12-19
Abstract: A method and apparatus is disclosed which reduces or removes axial loads on the drive string of a rotary downhole pump, i.e. tensile loads due to the hydrostatic load of the pumped liquid on the pump rotor, and/or at least part of the weight of the drive string, or thrust loads caused during pressurized fluid injection operations by backpressure of injected fluid on the pump rotor. This substantially prevents drive string/production tubing friction, wear and/or buckle in downhole rotary pumpingarrangements operated in straight or curved well bores. When used in connection with fluid production pumping arrangements, the apparatus reduces the friction between the drive string and the production tubing of a downhole rotary pump for the pumping of well fluids which pump has a pump rotor connected to the drive string and is operated in a well bore. When used in connection with fluid injection pumping arrangements, the apparatus prevents drive string buckle, especially in curved well bore situations. The apparatus includes a support for rotatably supporting the drive string in the production tubing at a location above the pump, and a fluid passage for permitting the pumped fluid to flow from the pump to a wellhead of the well. The support includes an axial load bearing structure for supporting, from the production tubing, at least part of an axial load on the drive string either generated by the hydrostatic load of a pumped liquid on the pump rotor or backpressure of injected fluid on the pump rotor. The fluid passage is shaped and constructed such that the pumped fluid can flow from the pump past the axial load bearing means to the wellhead. In fluid pumping applications, the apparatus can also be used to support at least part of the weight of the drive string to reduce the axial load on the drivehead.
