Title: Apparatus for everting a lining material
Inventor: GOTO RYOICHI
IPC: F16L55/163
Filed: 2005-12-20
Abstract: A pipe lining material is wound in a roll on a rotary body using an electric motor, and stored in a storage container. Wen everting, compressed air is applied within the storage container to pull the lining material from the storage container and evert it via an eversion nozzle attached to the storage container. At this time, the electric motor functions as an electric generator and brakes the pullout of the pipe lining material. With such a constitution, the pullout speed of the pipe lining material is substantially constant and the pipe lining material can be smoothly everted with little pullout resistance.

Title: Gain stabilization apparatus and methods for spectral gamma ray measurment systems
Inventor: MICKAEL MEDHAT
IPC: G01T1/17
Filed: 2006-01-12
Abstract: Apparatus and methods for measuring gamma ray energy spectra wherein the gain of the measurement system is continuously and automatically adjusted to a standard gain. Gain of the system is controlled automatically through analysis of the measured energy spectra. Alternately, the gain of the system is controlled by the use of a calibration source and the operation of the system at a standard and amplified gain. Gain control can be improved further by combining both the spectral analysis and calibration source methodology. The system can be embodied in a wireline or logging-while- drilling borehole logging systems that naturally occurring or induced gamma ray spectra. The system can also be used in non-borehole applications including non- borehole gamma ray spectral systems such as computer-aided-tomography scan systems, security scanning systems, radiation monitoring systems, process control systems, analytical measurement systems using activation analysis methodology, and the like.

Abstract: A single-tank wastewater treatment system has a multiplicity of zones with different environmental conditions including aerobic, anoxic and anaerobic, to reduce the strength of highly concentrated wastewaters in terms of their content of organic carbonaceous compounds and nutrients, notably nitrogen and phosphorus. The upper zone of the treatment system operates under alternatively aerobic and anoxic conditions controlled by the on-off operation of an air blower that introduces air through air diffusers placed at the bottom of the upper zone. The lower section of the treatment system contains oxygen--depleted zones including anoxic conditions at the bottom and anaerobic conditions above the anoxic zones and below the air diffusers. The upper and lower sections of the tank are in fluid communication. Within the volume of upper aerobic zone and lower oxygen-depleted zones, loose carrier material or stationary objects are disposed to support the attachment of microbial biomass and the formation of microbial biofilm. Thus, the treatment system includes both suspended and immobilized microorganisms.

Title: Novel brevibacillus choshinensis and method for producing protein using the microorganism as host
Inventor: NISHIJYO TAKAYUKI
IPC: C12N15/01
Filed: 2004-11-08
Abstract: Brevibacillus choshinensis is  characterized in that  its extracellular proteolytic activity is extremely low and its protein secretion productivity is excellent, but it is desired that not only the extracellular proteolytic activity of the strain is further reduced but also the intracellular proteolytic activity thereof is further reduced. On the other hand, when Brevibacillus choshinensis is used as a host for protein pharmaceuticals and the like, it is also desired that it does not form spores and is readily sterilized.  The above problems have been solved by inactivating the sporulation-associated gene thereof and by cloning and inactivating the extracellular and intracellular protease genes thereof.
Patent CA-2546599-A1 (CA)
Inventor: MARKS JOEL
IPC: B25C5/16
Filed: 2004-11-08
Abstract: An anti-jamming design for a stapler track (80) provides reduced force to shear a staple (401) from a rack (400) of staples. In stapling, a front staple must be separated from a rack of staples to eject the staple out. Conventional staplers shear the glue that holds the staples together all at once, so the peak force to separate the staple is high. In the present invention the glue that holds staples together in a rack is sheared by a peeling action. Locally progressing sections of glue are peeled as the front staple is sheared from the adjacent second staple. According to one embodiment of the invention progressive shearing is provided by an asymmetric track front end, whereby the front staples are fully supported on one side only so that the staple rack twists as the striker (100) slowly presses down. The striker contacts the supported, higher, side of the staple first and the staple begins to shear from this higher side. When used in a low force spring actuated stapler, the present invention prevents the striker from resting atop the staple in an energized state if the stapling cycle is not properly completed.

Inventor: MARTIN JEFFREY R
IPC: F24F13/30
Filed: 2006-06-28
Abstract: An apparatus for recovering heat from exhaust air received from a restaurant kitchen. Rotating backwards inclined fan blades draw exhaust air from the kitchen along a flow path and impel it against walls of a housing, such that grease is removed from the exhaust air. A fan motor is positioned out of the flow path. The exhaust air is pushed out of the housing to a heat recovery coil directly downstream that is formed from a heat conductive material. The coil has an internal conduit through which a heat transfer fluid is supplied at a temperature below the exhaust air temperature, such that the fluid in the conduit is heated by exhaust air passing over the conductive material. After leaving the conduit, heat energy is transferred from the fluid to makeup air for return to, or to water for use in, the restaurant.

Title: Optical disk drive and method for driving the optical disk drive
Inventor: KONDO KENJI
IPC: G11B19/26
Filed: 2006-07-27
Abstract: An optical disk drive includes: an objective lens for converging a light beam onto an optical disk with an information storage layer; an actuator for moving the lens perpendicularly to the storage layer; an actuator driver for moving the lens at: a predetermined velocity by controlling the actuator's operation; and a disk position detector for detecting the position of the lens, when the focal point of the beam is located on the storage layer, as a disk position.      While the lens is being moved toward the disk to perform a focus finding operation, the moving velocity of the lens is set high until the lens reaches a velocity switching point, determined by reference to the disk position, and is set low once the lens has passed the point. The switching point is set farther away from the disk than the position of the lens is when the focal point of the beam is located on the storage layer of the disk.
