Title: Method and apparatus for separating non-condensable gases from vapor
Inventor: SAARI RISTO
IPC: B01D53/00
Filed: 1989-11-28
Abstract: Abstract The invention relates to a method and apparatus in which non-condensable gases are discharged from a condenser by bringing a mixture of the vapor and non-condensable gases, by means of cooling, into contact with an absorption medium maintained at a constant temperature, the vapor pressure of said absorption medium being lower than the vapor pressure in the gas mixture to be treated, whereby a portion of the vapor absorbs into the absorption medium, the partial pressure of the non-condensable gases in the mixture rises and the volume of gas to be removed from the process by some previously known pumping method decreases. An amount of vapor corresponding to the amount of absorbed vapor is vaporized from the absorption medium at a slightly higher temperature, and this vapor is condensed in, for example, the same condenser from which the non-condensable gases were removed.

Title: Mat-making apparatus for particleboard manufacture
Inventor: UFERMANN WERNER
IPC: B27N3/14
Filed: 1989-12-05
Abstract: An apparatus for forming a particle mat for the produc-tion of particleboard comprises a transport belt having a stretch moving in a longitudinal transport direction and forming a deposition surface in turn defining a floor of a deposition space, a dispenser upwardly delimiting the space and including a dispensing roller for depositing particles as a mat in the space on the longitudinally moving deposition surface, a pair of transversely spaced and longitudinally extending upper guides extending in the space generally at the dispenser, and a pair of transversely spaced and longitudinally extending lower guides extending in the space underneath the respective upper guides and generally at the deposition surface.  A pair of longitudinally extending, continuous, and transversely spaced flexible sheets each extend the full longitudinal length of the deposition space and have an inner edge secured to one of the guides of a respec-tive one of the pairs of guides and an outer edge.  The sheets each pass around the other of the guides of the respective pair of guides and therefore each have a section extending generally vertically between the respective upper and lower guides.          Tensioners engages the outer edges of the sheets and maintains the wall sections taut and generally planar between the respec-tive upper and lower guides.  Thus the deposition space is trans-versely delimited by the sections of the sheets.

Title: Formation of melt-spun acrylic fibers which are well suited for thermal conversion to high strength carbon fibers
Inventor: DAUMIT GENE P
IPC: D01F6/18
Filed: 1990-03-23
Abstract: IMPROVEMENTS IN THE FORMATION OF            MELT-SPUN ACRYLIC FIBERS WHICH               ARE WELL SUITED FOR THERMAL       CONVERSION TO HIGH STRENGTH CARBON FIBERS                Abstract of the Disclosure An acrylic multifilamentary material possessing an internal structure which is well suited for thermal conversion to high strength carbon fibers is formed via a specifically defined combination of processing conditions.  The acrylic polymer while in substantially homogeneous admixture with appropriate concentrations (as defined) of C1 to C2 nitroalkane and water is melt extruded and is drawn at a relatively low draw ratio which is substantially less than the maximum draw ratio achievable. During the melt extrusion a C1 to C4 monohydroxy alkanol preferably also is present in the substantially homogenous admixture.  The fibrous material which is capable of readily undergoing drawing next is passed through a heat treatment zone wherein the evolution of residual nitroalkane, monohydroxy alkanol and water takes place.  The resulting fibrous material following such heat treatment is subjected to additional drawing to accomplish further orientation and internal structure modification and to produce a fibrous material of the appropriate denier for carbon fiber production.  One accordingly is provided a reliable route to form a fibrous acrylic precursor for carbon fiber production without the necessity to employ the solution-spinning routes commonly utilized in the prior art for precursor formation.  One can now eliminate the utilization and handling of large amounts of solvent as has heretofore been necessary when forming an acrylic carbon fiber precursor.  Also, acrylic fiber precursors possessing a wide variety of cross-sectional configurations now are made possible which can be thermally converted into carbon fibers of a similar cross-sectional configuration.

Title: Method and apparatus for caller-controlled receipt and delivery of voice messages
Inventor: CARTER HOWARD E
IPC: H04M15/00
Filed: 1990-04-24
Abstract: A line interface unit for caller-controlled receipt and delivery of voice and/or data messages over a telephone system having a voice/data message facility, the message facility connectible to at least one calling station and a called station and normally having access prevention circuitry for preventing storage and forwarding of voice/data messages unless predetermined access codes are received and verified by the circuitry. In the preferred embodiment, the unit comprises a switch connected to a central office and having first and second positions and wherein signals are connected directly between the calling station and the central office when the switch is in the first position. The interf ace unit also includes circuitry for signaling the message facility and circuitry for monitoring call progress upon call initiation to the called station. Microprocessor-based control circuitry responds to detection of a predetermined condition at the called station upon-call initiation, to detection of a first predetermined code from the calling station indicating that the caller desires to leave a voice/data message for the called station, and to detection of a second predetermined code from the voice message facility, to establish a connection between the calling station and the message facility. Thereafter, a special data string is transmitted to the message facility which, upon receipt thereby, facilitates barrierless entry in and out of the message facility without the predetermined access codes.
Patent CA-2016642-A1 (CA)
IPC: G06T7/20
Filed: 1990-05-11
Abstract: Abstract of the Disclosure:         On detecting a drastical change, such as a scene change, between current and previous ones of successive pictures which are represented by a digital video signal and each of which comprises a predetermined number of picture elements, the digital video signal is processed by using correlations between the picture elements within each of the successive pictures to produce a processed signal which represents processed results for each of the successive pictures.  A statistical distribution of the processed results is calculated from the processed signal.  The statistical distribution of the processed results in the current picture is collated with the statistical distribution of the processed results in the previous picture to be produced as a change detection signal representative of the drastical change with reference to a relationship between the statistical distribution of the processed results in the current picture and the statistical distribution of the processed results in the previous picture.  The processed signal may be obtained by producing a difference signal between the digital video signal and a prediction signal predictive of the digital video signal by using the correlations.  Alternatively, an orthogonal transform is carried out for the digital video signal to produce the processed signal.

Abstract: Abstract A scroll-type hermetic compressor is disclosed including within a hermetically sealed housing a fixed scroll member assembly, an orbiting scroll member assembly, a frame member, and a crankshaft.  The fixed and orbiting scroll member assemblies each include a separately formed involute wrap member interconnected with a plate member by means of a plurality of pin members received within corresponding axial bores in the wrap member and plate member, respectively.  The plate member of the fixed scroll member assembly is mounted to the frame member, while the plate member of the orbiting scroll member assembly is mounted to a drive hub member operably coupled to the crankshaft.  In one embodiment, the interconnecting pin members fit loosely within the bores in the wrap member such that the wrap member is movable with respect to the plate member, thereby providing radial compliance between the fixed and orbiting scroll member assemblies during compressor operation.
