Patent CA-2212572-A1 (CA)
Title: Method and apparatus for disinfecting biological fluids through interaction with gases
Inventor: KEKEZ MLADEN M
IPC: A61M1/32
Filed: 1996-01-19
Abstract: Biological fluids, e.g. bodily fluids such as plasma/serum, semen, milk or blood, can be treated efficiently with ozone to inactivte certain viruses, bacteria, fungi etc. To effect and enhance the contact of such fluids with ozone, or another disinfecting or deactivating gas, the fluids are thoroughly nebulized, or atomized, i.e. dispersed into minute droplets. Nebulization has been found to afford a faster O3-fluid reaction rate than other known methods. It is proposed to create a fine "rain" of droplets to fall through a controlled atmosphere of O3/O2 and/or O3/inert gas mixture. Electric and magnetic fields are superimposed over the space through which the droplets are passed. Three types of nebulizers/atomizers are described: compressed gas (O3/O2 mixture) atomizer, ultrasonic nebulizer, and rotary nebulizer. The invention was tested on coliphage MS2 which is safe, easy to handle, and more resistant to chemical disinfections than viruses such as HIV. More than 7 log10 reduction in the virus viability was observed.
Patent CA-2212590-A1 (CA)
Inventor: JORDAN HENRY JOE JR
IPC: E21B33/1295
Filed: 1997-08-07
Abstract: A packer is disclosed which uses applied pressure to set the slips and initiate a compressive force on the sealing elements. The compressive force applied to the sealing elements moves components above the sealing elements and allows the available hydrostatic pressure in the wellbore to create an opposing force on the sealing elements to ensure that they properly set. The sealing elements are mounted directly to the packer body, thus eliminating a leakpath from the fluid pressure application port which is located below the sealing elements on the packer body. Various lock rings hold the set of the packer to avoid the creation of boost forces on the sealing elements from applied or induced pressures from above or below the sealing elements. Movement of the body is not required to accomplish setting of this packer. In applications with low hydrostatic pressure, the annulus can be pressurized to assist in obtaining the necessary pack-off pressure. The hydrostatic pressure continues to be available as a pack-off force even when the pressure below the packing element depletes as the reservoir depletes. The packing element, which is mounted directly to the packer body, eliminates leakpaths behind it, while, at the same time, the packing element is set by opposed forces; i.e., hydraulic from below and hydrostatic from above.

Title: Objective lens driving device and optical disc apparatus using the same
Inventor: INUI SHINRO
IPC: G11B7/135
Filed: 1997-08-18
Abstract: It is an object to perform a thin and compact design of the objective lens driving device. In order to achieve the above object, optical beam is passed through a space surrounded by a tracking coil and a focusing coil which are adjacent to each other and fixed in a holder. Further, it is another object to position the objective lens with high precision in an objective lens driving device for switching a plurality of objective lenses in accordance with the type of an optical disc. In order to achieve this object, magnetic substances which are radially extended with the sliding shaft at the center are provided in the lens holder, and the magnetic substances are located within a plane perpendicular to the plane constituting the magnetic gap and at the outside of the magnetic gap. Still further, in an objective lens driving device it is another object to prevent the occurrence of positional displacement of the objective lens due to resistance force of current supply means such as FPC. To achieve this object, a first objective lens and a second objective lens are arranged so that the objective lens arrangement angle at which the first and second objective lenses are arranged with respect to the shaft center of the sliding shaft is displaced, by a predetermined amount, from the magnetic circuit arrangement angle at which the magnetic substances and the magnets are arranged with respect to the shaft center of the sliding shaft.

Title: Improved differential including friction pack clutch means
Inventor: VALENTE PAUL J
IPC: F16H48/12
Filed: 1997-09-22
Abstract: A locking differential includes annular friction pack clutch assemblies for normally connecting the drive shaft of a vehicle to a pair of axially aligned driven axle shafts. A pair of clutch members are biased apart by a plurality of spring assemblies exch including a locking pin colinearly arranged relative to a helical spring. At one end, the locking pin is slidably mounted in a corresponding pin bore contained in one face of a first clutch member, the other end of the locking pin extending within an oversized spring bore contained in the opposing face of a second clutch member The helical spring is mounted in the bottom of the oversized bore and is compressed by the pin when the pin is releasably retained in an extended operable position by a removable fastener member, thereby to compress the friction packs between the clutch members and the adjacent casing internal wall surfaces. When one driver shaft overruns the other by a given amount, the associated friction clutch is disengaged to disconnect the overrunning shaft from the differential.
