Title: Apparatus for using hazardous waste to form non hazardous aggregate
Inventor: KENT JOHN M
IPC: F23J15/02
Filed: 1991-05-06
Abstract: Hazardous waste is formed into non-hazardous non-leaching aggregate by introducing the material to a rotary kiln where the large solids are at least partially combusted to form a primary aggregate. Gaseous combustion by-products and waste fines from the waste materials are introduced into at least one oxidizer having water-cooled metal walls. Some of the waste fines are melted to form a molten slag-like material that is removed from the apparatus and cooled to form non-hazardous aggregate. The portion of the material in the oxidizer that is not melted, is cooled, neutralized and subjected to a solid gas separation. The solid is reintroduced to the oxidizer with the primary aggregate where they are either melted or entrained within the molten material and become an integral part of the non-hazardous aggregate. <IMAGE>

Title: Bioerodible controlled delivery system.
Inventor: BOWMAN LYLE M
IPC: A61K47/34
Filed: 1993-12-17
Abstract: A controlled release medicament delivery system comprises a plasticized or unplasticized bioerodible polymer, such as a polyorthoester, suspended as a discontinuous phase in a hydrophobic liquid such as silicone oil or mineral oil as a continuous phase. Medicament desirably is entrapped at least partly by the discontinuous phase. The resulting delivery system is able to release the medicament in a controlled and sustainded manner. The formulation is particularly advantageous for use as a once-a-day eyedrop. During preparation, the polymer may be heated to an elevated temperature for a sufficient time to substantially reduce its molecular weight. Medicament may be added at a temperature above which there is complete phase separation.

Title: Fluid distributor, particularly for water distribution in irrigation systems
Inventor: STEPHANY CHRISTIAN
IPC: F16K11/072
Filed: 1994-08-16
Abstract: For the stepped line connection of a water inlet (7) to in each case one of a plurality of water outlets (8), a switching mechanism (17), which is located essentially in the dry and intended for a locking member (13), is designed such that it effects a switching operation only in the case of the spring-operated return stroke of its drive (16). The through-passage opening (50) of the locking member (13) can thus assume essentially the same position in the initial position of the distributor (1) as in the subsequent stroke end position, this resulting in very favourable flow conditions. <IMAGE>

Title: Method for carrying out real-time backup communication of IP communication
Inventor: SUZUKI MITSUO
IPC: H04L69/40
Filed: 2000-08-09
Granted: 2002-07-24
Abstract: Real-time communications are transmitted from a transmission side node 120 to a reception side node 130 via an internet protocol (IP) network 100 provided performance is deemed satisfactory. However if performance is deemed unsatisfactory the IP network is bypassed and the real-time communications are instead automatically diverted along a public network 110. If a real-time communication call is newly generated during the course of real-time communication on the public network then the newly generated real-time communication is made to go around the public network rather than the IP network. Performance is assessed by periodically transmitting echo test signals along the IP network. If the time interval between sending and receiving an echo test signal exceeds a predetermined allowed time interval then the quality of real time communication cannot be assured and performance is deemed unsatisfactory.

Title: Apparatus and method for training oarsmen
Inventor: VOHNOUT VINCENT JOSEPH
IPC: A63B21/22
Filed: 1990-11-02
Granted: 1993-07-14
Abstract: A pair boat simulator is provided including a housing which is mounted about a longitudinal roll axis upon supports above a training facility floor. Two racing shell seats are mounted within the housing adjacent simulated oars which are mounted, in turn, upon oarlocks positioned, in turn, upon outrigger assemblies. The simulated oars are foreshortened and include a blade flotation assembly at their tips along with load beam type force transducers. The oars serve to drive a rotatable mass such as a flywheel. Thus, the physical output of each oarsman is commonly coupled to the rotating mass. Instrumentation includes transducers looking to inclinations of the housing about the roll or longitudinal axis, oar elevation and sweep angle as well as blade rotation. These parameters are combined and developed under computer driven control into data presented at visual readouts made available both to the oarsman and coach. Such readouts include, for example, force versus sweep angle graphs, animated displays of heading, lateral position and hull velocity; values of effective power and rowing efficiency.

Title: Security mechanism for sliding panels
Inventor: KENT ROBIN JOHN
IPC: E06B3/46
Filed: 1993-07-03
Granted: 1997-09-17
Abstract: Various improvements to sliding panels are disclosed. In a first aspect, an elongate bottom section 6 for a sliding panel is provided, the section having an upturned U-shaped cross-section so that roller assemblies can be placed within the section at any desired position. According to a second aspect, a cover plate (11 or 12, Fig 2) for a sliding panel is provided, the cover plate fitting over an otherwise exposed structural fitting of the panel so that with the panel closed, the cover plate cannot be readily removed, thus enhancing the security aspects for interalia sliding patio doors. A frame for patio doors is provided (Fig 5) for on-site assembly from reinforced top, middle and bottom channels, upper and lower glazing panels and vertical side channels. A further improvement which is directed to providing enhanced security, comprises an adjustable height blocking mechanism (18, Fig 3) for positioning within a top retaining channel of a sliding panel assembly, the arrangement being configurable into a first configuration to allow insertion of the sliding panel between top and bottom retaining channels and then reconfigurable into a second configuration so as to limit upward movement of the sliding panel when the panel is in a closed position. <IMAGE>

Title: Plate heat exchanger
Inventor: KULL REINHARD
IPC: F28D9/00
Filed: 1996-02-06
Granted: 1999-10-27
Abstract: A plate heat exchanger comprises a plurality of heat exchanger plates stacked one above the other. The plates each have a peripheral edge projecting from its plate plane. The heat exchanger plates succeeding one another in each case are sealingly connected at their edges, so that flow ducts for at least two heat exchange media form between the plates. Each of these flow ducts is connected via openings in the heat exchanger plates to at least one other flow duct, so that a first heat exchange medium can flow through a first group of ducts loaded in parallel and a second heat exchange medium can flow through another group. So that a heat exchanger constructed in this way offers a satisfactory heat transmission capacity even in the case of widely varying volume flows of the media involved, the openings for the first heat exchange medium have a substantially larger cross section than the openings for the second heat exchange medium.
