Title: Knot pusher for videoendoscopic surgery
Inventor: MANGUM WILLIAM K
IPC: A61B17/04
Filed: 1994-04-13
Abstract: Abstract Four embodiments of videoendoscopic knot pushers are shown having a main body and first and second fingers whose ends are shaped in a smooth rounded shape to guide a suture and knot into position with a patient's body.  The finger members define either a "V" shaped cleft or a smooth walled channel between them for grasping the suture.  One embodiment of the invention has second and third channels for retaining the suture in the fingers even during retraction of the main body.  Another embodiment of the present invention has a spiral channel formed "upstream" of the finger members for retaining control of the suture even if the suture slips out of the grasp of the channel formed by the first and second finger members.

Title: Auto cpap system
Inventor: REMMERS JOHN E
IPC: A61M16/00
Filed: 1992-11-13
Abstract: The present invention relates to systems and methods for automatically and continuously regulating the level of nasal pressure to an optimal value during OSA treatment. OSA therapy is implemented by a device which automatically re-evaluates an applied pressure and continually searches for a minimum pressure required to adequately distend a patient's pharyngeal airway. For example, this optimal level varies with body position and stage of sleep throughout the night.      In addition, this level varies depending upon the patient's body weight and whether or not alcohol or sleeping medicine has been ingested.

Title: Nonproliferative light water nuclear reactor with economic use of thorium
Inventor: RADKOWSKY ALVIN
IPC: G21C5/18
Filed: 1993-02-04
Abstract: A light water nuclear reactor, which derives most of its energy from thorium, utilizes a seed-blanket core arrangement and a nonparasitic and mechanically simple control system. Neither the initial fuel loading nor the fuel discharged from the reactor is useable for nuclear weapons purposes. The initial fissile fuel is enriched uranium, U-235/U-238 (20:80), which is known to be nonproliferative. The discharged fissile fuel consists of (1) uranium with about ten percent U-235 content, (2) less than one percent of the amount of plutonium produced in conventional light water reactors, (3) U-233 denatured by being uniformly mixed with more than twice as much U-238 and (4) the remaining thorium. About seventy-five to eighty percent of the reactor energy is derived by fissioning in place the U-233 formed in the thorium, thus avoiding the very expensive process of extracting and fabricating the highly gamma-active U-233 into fuel elements.

Title: Sulfonated cellulose and method of preparation
Inventor: SHET RAMAKANT T
IPC: D21H27/20
Filed: 1994-12-15
Abstract: Disclosed is a method for the surface modification of cellulose fiber and the resulting product, sulfonated cellulose.  Cellulose is first oxidized, preferably with sodium metaperiodate (NaIO4), to form dialdehyde oxycellulose, which is then reacted with sodium bisulfite (NaHSO3) to produce sulfonated cellulose.  Sulfonation of the cellulose fiber significantly increases the dry and wet tensile strength as well as the wet strength:dry strength ratio, making this modified cellulose fiber extremely useful in a wide variety of paper products requiring a combination of good strength in both wet and dry applications.
Patent CA-2140515-A1 (CA)
Inventor: EAVENSON JIMMY N SR
IPC: H02J7/14
Filed: 1995-01-18
Abstract: A charging system includes a high capacity charging circuit having the original internal engine alternator connected substantially in parallel with an auxiliary alternator by a simple wiring harness arrangement that easily plugs into the existing connectors for the internal engine alternator circuit so that the outputs of the alternators are cumulative.  The auxiliary alternator is relatively compact, and the original engine alternator circuit remains substantially unaltered.  The regulators for the two alternators include sensory inputs which are connected to each other.  The alternators provide redundancy and a fail-safe backup mode so that if one of the systems fails, that system can be quickly disconnected from the remaining system without disabling the entire vehicle.

Abstract: A method and device in a paper machine or in a finishing device of a paper machine, in particular in a slitter-winder, for collecting and removing dust and other particles that are separated from a web.  In the method, an air blowing is directed at the web to separate dust from the web and a suction effect is applied to the web to remove the separated dust out of connection with the web.  Preferably, a high-pressure blowing is directed at the web at a blowing region to separate the dust from the web, before the high-pressure blowing in the running direction of the web, dust and other particles separated from the web are sucked off in a first suction region and after the high-pressure blowing in the running direction of the web, the dust and other particles are sucked off in a second suction region.   The device includes a pressurized chamber space in which there is a nozzle opening for the applica-tion of an air blowing to the web and a suction opening/openings for removing the dust present in connection with the web.  The air chamber in the device is pressurized and a high-pressure blowing is blown through the nozzle opening of this air chamber toward the web and the suction openings of the device are placed before and after the nozzle opening in the running direction of the web.

Title: Microbiological method for the decomposition of organic wastes
Inventor: KNEER FRANZ XAVER
IPC: C05F17/02
Filed: 1994-01-17
Abstract: The invention concerns a microbiological method for the decompo-sition of organic wastes, the waste material being subjected to a compost-ing process under aerobic conditions in a closed container to which air is supplied. Air is passed through the waste material at intervals, the spent air being drawn off together with the gaseous decomposition products. The length of the intervals between the air feed periods is controlled as a function of the lowest value of the O2 concentration measured in the spent air. The spent air which collects in the space above the composting material is preferably drawn off at the same time as air is supplied, or shortly afterwards, the O2 concentration being measured at this time. Al-ternatively, the O2 concentration in the space between the heap of waste and the container end wall or the O2 concentration of the gas in the heap of waste can be monitored.
