Inventor: EDELSTEIN PHILIP
IPC: C22B3/26
Filed: 2001-03-30
Abstract: Process for improving recovery of copper and reducing raw material costs, from a copper-containing source by SX-EW. The process comprises the steps of mixing an acidic copper-containing PLS obtained by leaching a copper-containing source with an acidic leachant, usually sulfuric acid, with an aqueous acidic cupric chloride solution spent printed wire board etchant, to produce an acidic cupric chloride/copper sulfate-containing mixture. This mixture is subjected to SX-EW to recover the copper as copper cathode.

Abstract: Activating a switch by a handset where the switch is manually activated when the user wishes to answer an incoming call. While the switch is in the deactivated state, the handset transmits to a sound card within a personal computer a multi-frequency tone which is detectable by the sound card. When the manual switch is activated, the handset ceases to transmit the multi-frequency tone to the sound card. The sound card detects the absence of the multi-frequency tone to determine if the handset is answering a call. In traditional telephony terms, when the manual switch is activated, this is the offhook condition. When the manual switch is deactivated, this is the onhook condition. When the user is done with the call and deactivates the manual switch, the handset again generates the multi-frequency tone that is subsequently detected by the software via the sound card. Then, the software knows to signal the other party on the call that the call has been terminated. A headset is similarly designed to provide the same multi-frequency tone generation features as the handset.

IPC: A61F2/28
Filed: 1999-12-03
Abstract: An implantable, biocompatible, osteogenic bone graft comprises at least one zone of impermeability to soft tissue ingrowth which is integral with the bone graft.

The bone graft can be employed in a wide variety of bone repair procedures.
Patent CA-2355373-A1 (CA)
Title: Retrieval device made of precursor alloy cable
Inventor: MCALISTER GARY B
IPC: A61B17/22
Filed: 2000-10-26
Abstract: A medical retrieval device for retrieving foreign objects from a patient and the method of constructing the device are disclosed. The device incorporates a wire cable composed of a precursor alloy to a superelastic material to improve durability of the device. Because precursor alloys exhibit a linear stress-strain relationship and a yield point associated with a relatively high stress level, the device transfers greater stresses before experiencing deformation. Thus, greater crushing forces can be achieved using a device of this type. These crushing forces may be needed when the foreign object is too large to remove intact. This property also facilitates the device in dilating ducts to retrieve foreign objects. Using the precursor alloy additionally eliminates the need for heat treatment of the cables used in constructing the device. A retrieval device made of precursor alloy cable also is less susceptible to permanent deformation and unwinding during use.

Title: Optical fiber, method of making optical fiber preform, and method of making optical fiber
Inventor: KATO TAKATOSHI
IPC: G02B6/036
Filed: 2001-08-27
Abstract: An optical fiber comprising a core region 100 doped with C1 which raises the refractive index; and a cladding region 200, provided at the outer periphery of the core region 100, having a cladding layer 201 doped with F which lowers the refractive index is formed. The cladding region 201 to become the outermost cladding layer is configured such that the doping amount of F successively decreases within an outer peripheral part 205 including the outer periphery thereof to a predetermined doping amount which is the minimum doping amount of F within the cladding layer 201. Therefore, the stress within the optical fiber is dispersed into the outer peripheral part 205 having an enhanced viscosity, whereby the stress concentration into the core is suppressed. Since the favorable tension range at the time of drawing the optical fiber becomes wider at this time tension control is facilitated.

Patent CA-2371814-A1 (CA)
Inventor: RENNIE PAUL S
IPC: C07H21/00
Filed: 2000-02-25
Abstract: It has now been determined that antisense therapy which reduces the expressi on of TRPM-2 provides therapeutic benefits in the treatment of cancer. In particular, such antisense therapy can be applied in treatment of prostate cancer and renal cell cancer. Addition of antisense TRPM-2 ODN to prostatic tumor cells in vivo is effective for delaying the onset of androgen independence. Thus, prostate cancer can be treated in an individual sufferin g from prostate cancer by initiating androgen-withdrawal to induce apoptotic cell death of prostatic tumor cells in the individual, and administering to the individual a composition effective to inhibit expression of TRPM-2 by th e tumor cells, thereby delaying the progression of prostatic tumor cells to an  androgen-independent state in an individual. Combined use of antisense TRPM- 2 and taxanes synergistically enhances cytotoxic chemosensitivity of androgen- independent prostate cancer. In addition, it has also been found that antisense TRPM-2 has beneficial effect for other cancer types. Specifically,  antisense TRPM-2 ODN enhances chemosensitivity in human Renal cell cancer, a  normally chemoresistant disease with no active chemotherapeutic agent having  an objective response rate higher than 10 %. Radiation sensitivity is also enhanced when cells expressing TRPM-2 are treated with antisense TRPM-2 ODN.  Thus, the antisense TRPM-2 ODNs can be used to enhance hormone sensitivity, chemosensitivity and radiation sensitivity of a variety of cancer types in which expression of TRPM-2 has been observed.
