Patent CA-2263686-A1 (CA)
Inventor: LAI CHING-SAN
IPC: A61P31/04
Filed: 1997-08-28
Abstract: In accordance with the present invention, there are provided methods for the in vivo reduction of free iron ion levels in a mammalian subject. The present invention employs a scavenging approach whereby free iron ions are bound in vivo to a suitable physiologically compatible scavenger. The resulting complex renders the free iron ions harmless, and is eventually excreted in the urine of the host. Further in accordance with the present invention, there are provided compositions and formulations useful for carrying out the above-described methods. An exemplary scavenger contemplated for use in the practice of the present invention is a dithiocarbamate-containing composition. This material binds to free iron ions, forming a stable, water-soluble dithiocarbamate-iron complex. Thus, the present invention relates to methods for reducing in vivo levels of free iron ions as a means of treating subjects afflicted with iron overload and non-iron overload diseases and/or conditions, such as thalassemia, anemia, hereditary hemochromatosis, hemodialysis, stroke and rheumatoid arthritis. Dithiocarbamate-containing scavengers are administered to a host in need of such treatment; these scavengers interact in vivo with free iron ions, thereby forming a stable dithiocarbamate-metal complex, which is then filtered through the kidneys, concentrated in the urine, and eventually excreted by the subject, thus reducing in vivo levels of free iron ions.

Abstract: A method and apparatus to assist in testing of fire alarms and other emergency warning systems. Such a system typically contains annunciator devices (14) such as sounders, speakers or strobe lights and these must normally be checked for acceptable operation on a regular basis. The invention enables a single or married individual to activate the alarm system briefly, without creating undue disturbance for surrounding occupants of an office or apartment block for example. The individual can then inspect an event recorder (20) located near or integral with each annunciator, to check that the respective annunciator has operated correctly. Operation of the annunciator may be assessed by monitoring input or output of the annunciator, such as current levels, or audible or visible output. Alternatively, each annunciator may communicate an indication of acceptable operation directly to a main control panel (11).

Patent CA-2267586-A1 (CA)
Inventor: POULIOT LUC
IPC: G01N25/72
Filed: 1999-04-13
Abstract: Disclosed is a method for the detection of near surface defects in components, such as engine block cylinder walls. In a first step, a flow of cold air is applied to an area to be inspected, thereby establishing a heat flow from the inside-out. In a second step, the cooled area is subjected to an inspection by reversed thermography in order to locate any cold spots which would be indicative of defects. The amount of heat extracted by the cold air is a function of the difference in temperature between the air and the surface. In steady-state conditions, that temperature reaches an equilibrium where the cooling rate equals the amount of heat continuously flowing from the hot mass underneath the cooler surface. Where there is a bonding defect, the equilibrium temperature will be lower because heat flow towards the surface is disrupted. Therefore, defects appear as cold spots, in reversed contrast with traditional thermography.

Title: Implantable surgical marker
Inventor: BOEHM MICHAEL E
IPC: A61B19/00
Filed: 1999-06-23
Abstract: An implantable marker for implantation in tissue of a surgical patient is disclosed. The marker has a base and an elevated bridge. A pair of legs descend from first and second transitions of the bridge. Each leg has a distal tip, a generally straight leg arm adjacent the tip, and a camming marker surface between the transitions of the base and the straight leg arm. The camming marker surfaces extend outwardly from the straight leg arms of the legs. In its open configuration, the first and second straight leg arms of the legs of the marker are generally parallel to each other. In its closed configuration, the first and second straight leg arms converge towards each other, and a marker apex is formed at the distal tips of the legs. The marker is particularly adapted for fixation in tissue to mark the site of a lesion or other abnormal tissue which may be removed during a biopsy procedure, for example a breast biopsy procedure. Advantageously, the camming marker surfaces of the legs of the marker facilitate the ability to form the marker upon pushing the marker distally into the tissue, thus insuring deep penetration of the marker and the grasping of a sufficient amount of tissue to securely fix the marker to the tissue.
