Patent CA-2258106-A1 (CA)
Inventor: MAASS DAVID
IPC: F16F1/36
Filed: 1997-06-12
Abstract: A fiber reinforced composite flywheel for energy storage has a plurality of disks (3) in the form of a coil produced of continuous hoop and radial fibers (4), each disk (3) having a mix of fiber types in the hoop direction, relatively strong fibers disposed about an inner section (11) of the disk (3), an intermediate section (12) of the disk comprised of relatively strong and relatively lower strength fibers, and an outer portion having a mix of fibers containing fewer relatively strong fibers. A fiber reinforced composite flywheel, alternatively or in addition, has a higher volume of radial fibers (4) diposed about the intermediate section of the disk, to increase radial strength in a banded area of the disk subject to increased radial stress.  Preferably, the disk (3) is composed with a 3-dimensional orthogonal weave architecture which allows the fibers to shear during weaving to provide minimum distortion of the spiral woven disk. Constructing a spiral woven composite flywheel disk (3) in accordance with the invention optimizes stress and strength properties to increase operating speed and energy storage capacity at minimum cost.

Title: Methods and apparatus for transmyocardial direct coronary revascularization
Inventor: WHITT JASON BRIAN
IPC: A61F2/07
Filed: 1997-08-25
Abstract: This invention is methods and apparatus for direct coronary revascularization wherein a transmyocardial passageway (10) is formed between a chamber of the heart (LV) and a coronary blood vessel (CBV) to permit blood to flow therebetween.

Patent CA-2265236-A1 (CA)
Title: Polarizing beam splitter/combiner
Inventor: CHENG YIHAO
IPC: G02B6/28
Filed: 1999-03-11
Abstract: A polarization beam sputter combiner uses a birefringent crystal that is a fraction of the size of conventional crystals used in similar devices. Since the crystal is considerably shorter in length, the beam passing through the crystal can be uncollimated, spreading very little from one end to the other. Launching uncollimated beams through a short small crystal obviates the requirement for lenses at the end face of the crystal having two waveguides coupled thereto. Since lenses are not required the waveguides at the input/output end face can be very closely spaced apart. Conventional tensed devices utilizing a pair of lenses at an input/output end face must be considerably larger in order to accommodate the lenses and resulting collimated beams.

Title: Method and apparatus for tissue enlargement
Inventor: KAISER DANIEL
IPC: A61H7/00
Filed: 1998-07-31
Abstract: An apparatus and method for enlargement of soft tissue, such as breast, including a vessel or dome configured to fit over the tissue which is to be enhanced or enlarged. The dome or vessel has a sealing cushion of elastic material which surrounds and encompasses the perimeter of the base of the vessel.      The cushion includes a fluid compartment which is compressible. The fluid compartment is deformable such that when the vacuum is applied to the sphere, the seal material and compartment deform, isolate, and diffuse the pressure on the skin. The apparatus also includes a vacuum pump with a power source, a pressure sensor to regulate the pressure, or vacuum provided by the pump. The dome also includes a valve mechanism for controlling the ingress and egress of the vacuum to the interior of the dome. This valve will automatically close so that the pump may be removed from the dome and the pressure or vacuum therein be maintained. This valve also includes a release mechanism to remove or exhaust the vacuum in case of discomfort or emergency. The domes may also have different configurations, including rectangular, though normally they will remain as a sphere to maximize and equalize the augmentation of the flesh or tissue within the confines of the dome. The dome also is formed with a footed rim which is embedded in a deformable elastic cushion with a fluid pocket to augment the deformation and consequent reduction in the per square inch pressure applied to the tissue of the wearer.

Title: Whipstock apparatus and methods of use
Inventor: SIEBER BOBBY G
IPC: E21B7/08
Filed: 1995-02-21
Abstract: An oil field Whip-Anchor System, for deviating a wellbore, which uses an improved whipstock (1) incorporating a new setting apparatus and method, attached to a mechanical (14M) or hydraulic anchor packer is disclosed. The complete Whip-Anchor System also includes an apparatus and method for retrieving the Whip-Anchor if it is used in wellbores which require retrievable wellbore. deviation tools. The new apparatus reduces the number of whipstock bodies that must be warehoused to three fundamental types which fit all commonly used wellbores. The apparatus permits the proper "set" of a mechanical packer without fear of shearing the releasable attachment device currently used in the industry and permits an operator to "bottom hole wash" while setting a mechanical packer in a wellbore. The same apparatus and similar techniques are used for both mechanical or hydraulic packers. The system utilizes a slot cut in the face (11) of the whipstock for setting (13) and retrieval (12). Other improvements include a pinned spring loaded hinge assembly (6) which assures that the tip of the whipstock will fall against the wellbore, a deflector plate (7) that uses a surface hardening or polycrystaline diamond inserts to reduce wear on the top portion of the device during the window milling operation. Also disclosed are additional downhole tools for use with the Whip-Anchor System.

IPC: C22B1/26
Filed: 1998-04-10
Abstract: A recycling process for zinc-rich solid waste containing zinc oxide, Cu oxides and impurities normally present in brass, in which a mixture is formed containing the waste with a finely divided solid reducing agent and a binder, and the mixture is compacted as agglomerates with open pores. The agglomerates are added into a treatment reactor containing a bath of liquid copper or brass metal, in which the zinc and copper oxides are reduced, to obtain in the treatment reactor after the reduction, a new brass in liquid form and a new waste. The new liquid brass is transferred into a fusion and casting furnace, in which its composition is optionally adjusted, and the new liquid brass is cast to form a product. Any waste present in the treatment reactor and the casting furnace are recycled using this process.

Inventor: LASSON REX H
IPC: E05F3/04
Filed: 2000-04-18
Abstract: A door closer with a plastic (nylon) plug in an aperture in the top of the door closer body. In the event of a fire, as the door heats up, the door closer body also heats up. When the temperature of the door closer reaches approximately 250° F, the hydraulic fluid within the door closer will begin to emerge from the plastic plug area and spills over and collects in the top of the door closer body casting which forms an open surfaced fluid retaining reservoir. The contained fluid smokes and evaporates from the heat. No fluid escapes down to the door and the floor.      This reduces the chance of causing a fire on the non-fire side of the door and frame.
