Abstract: PCT No. PCT/US92/02028 Sec. 371 Date Nov. 22, 1994 Sec. 102(e) Date Nov. 22, 1994 PCT Filed Mar. 13, 1992 PCT Pub. No. WO93/17791 PCT Pub. Date Sep. 16, 1993A method and apparatus for varying an electrically variable current limiting reactor (VICLR) ( 16) are provided in cooperation with an electrostatic precipitator automatic voltage control system. The inductance of VICLR (16) is varied by altering the DC current in control winding (66) of VICLR (16). A power source (10) connects serially to an inverse parallel SCR1 and SCR2, to VICLR (16), and to a TR set comprising a transformer (18) and rectifier (20) which supply power to precipitator (22). System electrical characteristics on both sides of the TR set are monitored. Computer (40) uses these monitored values to continuously calculate form factor and fractional conduction values. Step-down transformer (60) is connected to solid state relay (62) which is in turn connected to full wave bridge rectifier (64). Rectifier (64) is connected to control winding (66) of VICLR (16). Solid state relay (62) is also connected to computer (40). Solid state relay (62) can be triggered on each half cycle thereby providing DC current pulses to VICLR (16). The number of pulses supplied to said control winding within a predetermined time span can be altered thereby changing the net current in control winding (67) of VICLR (16), and hence, altering the inductance. The number of half cycles applied may be manually altered by an operator or responsive to system operating conditions, including but not limited to, form factor and fractional conduction.

Title: Electrophysiological sensing, for mapping, pacing and ablating
Inventor: GOLDREYER BRUCE N
IPC: A61B5/296
Filed: 1994-01-05
Abstract: Mapping of electrophysiologic activation within the human heart is achieved for areas within the myocardium by utilizing a catheter (32) having at least one pair of orthogonal sensors (34-46) disposed on the catheter (32). Orthogonal sensors (34-46), which ace comprised of electrodes generally disposed circumferentially on the catheter (32) at given longitudinal points spaced 1-5 millimeters along the catheter (32), receive signals which are differenced within a differential amplifier (50) to produce a signal indicative only of the localized biopotential heart activity at a predetermined point in the myocardium. The orthogonal sensors (34-46) are disposed adjacent to the stimulating tip (58) of the catheter (32) to allow sensing of the localized cardiac activity adjacent to or in contact with the tip during the pacing procedure or during the delivery of energy during ablation. Sensing of the localized activity occurs simultaneously with pacing or ablation so that electrocardiograms of the stimulated or ablated tissue can be recorded.

Filed: 1995-09-25
Abstract: A handle for permanent attachment to a toilet lid, and a handle for permanent attachment to a toilet seat. When using the handles, a person does not need to have direct hand contact to the toilet lid or toilet seat. The handles can be used separately from each other, or together as one unit. Each handle has a portion that extends outwards and provides attachment to the desired surface. Each extended portion has an adhesive type material on its upper surface. Because each handle is attached separately, the toilet lid and toilet seat can be maneuvered separately from each other. And because the handles are attached close beside each other, it is also possible to manuever the toilet lid and toilet seat at the same time. Each handle is contoured to fit snugly beside the other handle, so that the two handles may appear to be one device. And the handles are designed to lie as near as possible to the toilet lid and toilet seat, to avoid unduly detracting from the decor of the washroom facilities.
Patent CA-2160224-A1 (CA)
Title: Bispecific antigen-binding molecules
Inventor: RING DAVID B
IPC: C07K19/00
Filed: 1994-03-21
Abstract: The present invention relates to a class of molecules called "antigen forks" that inhibit cell growth. These antigen forks possess separate binding elements for two different cell surface antigens and are believed to heterologously crosslink the antigens by binding to them. The two antigens recognized by an antigen fork differ in at least one cellular functional quality, but are simultaneously expressed on the surface of at least one cell type targeted for killing or growth inhibition. Such targeted cells include tumor cells and virally-infected cells. It is preferred that the antigen fork be designed so that the two antigens it recognizes are seldom or never simultaneously expressed on normal cells. The antigen fork is preferably a bispecific antibody, but may also be constructed from binding elements that are not derived from antibodies. The present invention also relates to a hybrid hybridoma that produces an antigen fork and a method for treating a patient with cancer or a viral infection by administering an antigen fork. It is preferred that a cytotoxic agent such as deferoxamine or cisplatin is sequentially or simultaneously administered to the patient.
