Patent CA-2127676-A1 (CA)
Inventor: NEBOLON JOSEPH F
IPC: A61F5/01
Filed: 1994-07-08
Abstract: A hinge assembly is provided for an orthopaedic brace having a rotatable hinge and a detent mechanism to automatically, yet releasably, lock the hinge in a fixed position or rotation. The hinge includes two rotatably attached members and the detent mechanism includes an indentation formed in the attached end of one member and a block pivotally mounted on the other member. The block has a locking projection that is biased toward the indentation and cooperates therewith to provide three positions of operation, a locked position, a release position, and an activated position. In the locked position, the locking projection fittingly engages the indentation, thereby substantially preventing rotation of the hinge. The release position displaces the locking projection a radial distance away from the indentation, thereby permitting the hinge to rotate freely. In the activated position, the block disengages the indentation and maintain an angular distance therefrom so that the detent mechanism does not obstruct rotation of the hinge, but enables automatic repositioning of the hinge assembly to the locked position whenever the locking projection and indentation angularly realign.

Abstract: A method and system for improving the capability of a surface (14) of an organic structure (16) to bond with another material includes irradiating a target area of the surface of a structure with pulsed, incoherent optical energy (18) from an optical energy source (12) having wavelength components which range from 170-5000 nanometers at an intensity sufficient to photodecompose any adventitious organic substances on the surface and to photodecompose a thin layer of molecular bonds forming the surface of the structure; and exposing the target area of the surface (14) to an ionized gas stream (24) from an ionized gas generator (26) that chemically reacts with the target area of the surface to increase the surface free energy of the surface. A similar method may also be employed to improve the bondability of a metal surface by impinging a target area on a metal surface with a stream of particles (36) to preclean and dislodge any inorganic substances from the surface; and then irradiating the target area of the surface with pulsed, incoherent optical energy (18) having wavelength components in the range of 170-5000 nanometers at an intensity sufficient to photodecompose any remaining organic substances present on the surface.
Patent CA-2134763-A1 (CA)
Title: Bystander effect tumoricidal therapy
Inventor: CULVER KENNETH W
IPC: A61K48/00
Filed: 1993-05-03
Abstract: A method for treating a tumor involves the initial identification of the tumor as one displaying a "bystander effect", whereby in vivo transfer of a gene conferring sensitivity to chemotherapeutic agent affects both transformed and non-transformed tumor cells. Into a tumor thus characterized is introduced in situ a retroviral vector containing the sensitizing gene. The retroviral vector, which may be a replication-defective or a replication-competent, can be introduced directly (if it is replication-competent) or can be provided by means of a packaging cell line.  Treatment of the patient with the chemotherapeutic agent thereafter effects tumor regression when as few as 10 % of tumor cells are transformed, while normal tissue is not damaged. The anti-tumor impact of the treatment can be increased when the transducing vector also encodes an immune response-enhance substance such as IL-2 or another cytokine.

IPC: F16C17/00
Filed: 1995-03-08
Abstract: A method for providing a tubular roll mantle of a roll for a paper machine or equivalent with glide bearings and a roll including glide-bearings. The roll mantle is supported on a stationary roll axle by hydraulic glide-bearing members acting upon the roll mantle or upon the roll ends. The bearing members are loaded hydraulically by a pressure medium. The roll mantle is supported on the roll axle by at least one pair of glide-bearing members which acting radially and/or axially in opposite directions. When an outside force that shifts or attempts to shift the roll mantle in the direction transverse to the main loading direction and/or in the axial direction is applied to the roll mantle, the pressure in the glide-bearing member placed at the side of the higher loading is adjusted to a level higher than the pressure in the glide-bearing member acting in the opposite direction so that the outside forces are neutralized. In another embodiment, the roll mantle is permitted to be shifted over a certain distance in the main loading direction. When the roll mantle approaches its preset extreme position in this direction, the movement of the roll mantle is brake down, and finally the movement is stopped in its extreme position by the glide-bearing members.

Title: Method of measuring flow velocities using tracer techniques
Inventor: ROSCOE BRADLEY A
IPC: E21B47/10
Filed: 1995-06-20
Abstract: A method of measuring flow velocities in flowing fluids comprises injecting into the flow a non-radioactive tracer having a neutron capture cross section higher than that of the flowing fluids, for example a gadolinium compound, and measuring the neutron capture cross section in the fluid downstream of the injection point to detect the passage of the tracer and hence determine the time of flight. By making the tracer miscible with only one phase (typically the continuous phase) of a multi-phase fluid, it is possible to measure the flow velocity of that phase. The neutron capture cross section can be measured by irradiating with neutrons from a pulsed neutron generator and measuring capture y rays with a scintillation detector.
