Title: Liquid-sealed vane oscillator
Inventor: BLUMENAU LEIF
IPC: F04C29/00
Filed: 1999-04-16
Abstract: A liquid-sealed vane oscillator includes a housing defining a cavity corresponding to part of a virtual annulus centered around, and extending at least 180° about, an axis of rotation and delimited by first and second ends. A vane is mounted rotatably within the cavity. The vane includes a first seal and a second seal carried with the vane and deployed so as to subdivide the cavity into a first chamber of variable volume between the first end and the first seal, a second chamber of variable volume between the second end and the second seal, and an intermediate volume between the first seal and the second seal.  At least one port is provided in fluid communication with each of the first and second chambers. The oscillator also has an axial shaft, penetrating and extending from the cavity, which is mechanically coupled to the vane so as to allow exchange of mechanical power with an external device. A liquid circulation system supplies a liquid to the intermediate volume at a pressure such that the liquid flows past the first and second seals into the first and second chambers.

Abstract: Meat products are chilled to the extent that water present therein is frozen in order to facilitate slicing, subsequent processing, packaging or other handling of the meat products. The chilling is carried out in sequential steps. The first chilling step contacts the product with a brine of sodium chloride at a temperature below the freezing point of water. The resulting prechilled food product is subjected to a second chilling step with a calcium chloride brine which is at a lower temperature than the sodium chloride brine and which further reduces the core temperature of the food product to well below the freezing point of water.

Title: Telecommunications switching system with readily configurable supervisor control
Inventor: HEBERT MARK P
IPC: H04Q3/00
Filed: 1998-02-10
Abstract: A telephone switching system comprises a plurality of switching nodes interconnected by a call-switching network. The switching nodes are also linked by a host network to one or more hosts that exercise supervisory control over the nodes. The hosts communicate directly with one or more of the nodes, termed "switching nodes", by means of virtual connections over the host network. The other switching nodes, termed "slave nodes", are assigned to host nodes. The hosts communicate indirectly with the slave nodes by way of switching nodes to which they are assigned. Communications between a host and a slave node thus comprise messages: (a) over the host network between the slave node and the switching node to which the slave node is assigned and (b) by way of a virtual connection, between the switching node and the host.

Abstract: Methods of forming cationic liposome/nucleic acid complexes in which the complexes have a mean diameter of about 200 to about 300 nm are provided. The complexes are formed by combining a first solution of preformed cationic unilamellar liposomes with a mean diameter of from 100 to 150 nm, with a second solution of nucleic acid. Each of the solutions are equilibrated prior to mixing to temperatures of from 0 ~C to about 12 ~C, preferably about 2 ~C to about 7 ~C. The preformed cationic liposomes are typically prepared from an unsaturated cationic lipid, for example DODAC, DOTAP, DOTMA, DODAP, DMRIE, DORI, DOSPA and combinations thereof, and a neutral lipid, for example DOPE or cholesterol. The combination of the first and second solutions is typically carried out by gentle mixing over ice for a period of time of from about 10 to about 60 minutes.

Title: Phosphor thermometry system
Inventor: ALLISON STEVE W
IPC: G01K11/20
Filed: 1998-03-16
Abstract: An apparatus for measuring the temperature of a moving substrate (20) includes an air gun (110) with a powder reservoir (112), an air inlet port in communication with a pressurized air source (120), and an outlet nozzle (114) spaced from and directed toward the moving substrate (20).  The air gun (110) sprays controlled amounts of the powdered phosphor (102) onto the moving substrate (20), where the phosphor (102) assumes the temperature of the moving substrate (20). A laser (210) produces light pulses, and optics (200) direct the light pulses onto the phosphor (102) in response to which the phosphor (102) emits a luminescence with a decay rate indicative of the temperature of the phosphor (102). A  collection lens (200) is disposed to focus the luminescence, and a photodetector (270) detects the luminescence focused by the collection lens (200) and produces an electrical signal that is characteristic of the brightness of the luminescence. A processor (300) analyzes the electrical signal to determine the temperature of the phosphor (102).

Title: Process for high-temperature flash distillation of residue oils
Inventor: WEISS HANS-JUERGEN
IPC: C10G9/28
Filed: 1998-06-03
Abstract: According to the invention, liquid residual oil from processing crude oil, natural bitumen or oil sand is mixed in a mixer with hot coke as a heat carrier (heat-carrier coke) whereby 60 to 90 weight per cent of the residual oil is evaporated. The proportion of residual oil which has not evaporated, i.e. the part containing metalliferous asphaltenes is converted to oil vapour, gas and coke in the mixture with the heat-carrier.  The gases and vapours are extracted from the mixer separately from the granular coke and are subsequently cooled to obtain an oil product and gas. The coke extracted from the mixer is re-heated and returned to the mixer as a heat-carrier. The liquid residual oil is mixed with heat-carrier coke in the mixer according to a weight ratio of 1:3 to 1:30, said heat-carrier coke being at a temperature of 500 to 700°C. A residual liquid film forms on the granules of heat-carrier coke as a result of this mixing process. The majority of said residual film evaporates in the mixer at a lowest possible operating temperature of 450 to 600°C. The remaining residual liquid film on the coke is converted to oil vapour, gas and coke during a retention time of 6 to 60 seconds. Dry, pourable coke is extracted from the mixer, said coke being essentially free of any liquid constituents. The gases and vapours produced are extracted from the mixer after a retention time of 0.5 to 5 seconds.

Abstract: The present invention provides a method for treatment of grafts which comprises introducing a nucleic acid encoding an angiogenic agent into the cells of the graft. The graft may be treated ex vivo and then transplanted into the donor or may be treated after transplantation. The graft may be autologous, allogenic, xenogenic or a tissue engineered graft ("bio-artifical"  organ). The nucleic acid may be introduced to the cultured cells used to form the tissue engineered graft. Expression of the angiogenic agent by the cells of the graft promotes growth of new blood vessels (angiogenesis) providing the graft with a blood supply thus increasing the chances for graft survival.
