Title: Surface modification of castings
Inventor: JIANG JIAREN
IPC: B22C3/00
Filed: 2005-03-14
Granted: 2010-02-09
Abstract: A method of modifying a surface of a casting involves providing a casting mould; placing a perforated mask with the mould to define a masked area of the mould; spray-coating the masked area of the mould with a coating material selected for forming a surface layer on the casting; introducing a liquid casting material to the mould; and, solidifying the liquid casting material to form a surface modified casting. The present method reduces the tendency for the coating material to spall from the mould and permits the formation of thicker coating layers on the mould. Thicker and better quality surface layers may be formed on castings.

IPC: G21F9/00
Filed: 2004-05-06
Granted: 2009-04-28
Abstract: A decontamination system uses magnetic molecules having ferritin cores to selectively remove target contaminant ions from a solution. The magnetic molecule (101) is based upon a ferritin protein structure and has a central cavity (103) which contains a very small magnetic ferritin core (105) and a selective ion exchange function such as a porphyrin (107) and/or a crown ether (109) attached to its surface. Various types of ion exchange functions can be attached to the magnetic molecules, each of which is designed to remove a specific contaminant such as radioactive ions. The ion exchange functions allow the magnetic molecules to selectively absorb the contaminant ions from a solution while being inert to other non-target ions. The magnetic properties of the magnetic molecule (101) allow the magnetic molecules and the absorbed contaminant ions to be removed from solution by magnetic filtration.

Patent CA-2534754-C (CA)
Inventor: MCGARIAN BRUCE
IPC: E21B10/46
Filed: 1995-10-31
Granted: 2007-08-14
Abstract: This invention relates to a reaming tool for use in a subterranean well bore, the tool having axially spaced apart first and second reaming stages. 2-stage underreamers have been proposed in which the bodies of the upper and lower stages are releasably secured to each other by way of a threaded interconnection. Whilst such an arrangement considerably assists the manufacture of the tools it suffers from the disadvantage that very close manufacturing tolerances are necessary if, when the upper and lower body parts are screwed together, the blades on the upper and lower parts are to end up at exactly the correct angular position relative to each other. Further, the presence of a screwthreaded joint between the upper and lower stages of the tool reduces the strength of the body as compared with the strength of a unitary body.
