Title: Carrier recovery phase detector e.g. for QAM signal
Inventor: YAMANAKA KAZUYA
IPC: H04L27/38
Filed: 1997-04-15
Abstract: The detector estimates an ideal symbol (2a) from the carrier power or from the carrier amplitude. The realtime transmission in measured and a set of phase detection predictions (2b) determined. The phase error of the carrier is then calculated (3) to provide a phase error output for a symbol transmitted in real time from the set of phase prediction errors.  The carrier is preferably formed from two orthogonal components. The phase detector is used to calculate the carrier power or amplitude used for estimation of the ideal symbol.

Title: Stacked disc liquid filtration unit has off-centre penetrations for fluid take off
Inventor: ALEXANDER JOERG
IPC: B01D29/41
Filed: 1997-04-23
Abstract: The casing (8) accepts a stack of filter discs (1) interposed between inlet and outlet (12, 13). The filtration flow is transverse to the direction of stacking. The discs are held in position by end plates, with a central channel (2) for fluid supply to them.

Title: Power station dust moistening apparatus for use during free fall through pipe
Inventor: RUECKERT RAINER
IPC: B01F23/20
Filed: 1997-09-19
Abstract: An assembly moistens freely flowing bulk solids especially ash dust removed by filters from power station gases. The dust descends through a pipe (6) which has an upper ring section and a lower ring section, linked by an annular jet (1) gap through which water is introduced. The descending pipe (6) is surrounded by a water jacket (5) discharging to the annular jet (1). The ring sections (2, 3) forming the annular jet (1) gap are separate sections whose axial distance from each other is varied as required, forming a gap (7) between the two. The rims of the ring sections (2, 3) adjacent to the gap (7) have castellated edges with notched passages (4). The surrounding water tank (5) comprises two separate mantles (8, 9) which move axially back and forth in the direction of the descending pipe (6) and coming together. Each part of the water tank mantle is joined to one of the ring sections (2, 3). Ash descends through the pipe (6) in free fall passing the annular jet (1) through which water is sprayed to form a veil, uniformly wetting the dust. Additional water, taken from e.g. the sulfur dioxide gas washer, is mixed with a granular additive and introduced to the pipe (1) through the castellated passages (4) in the annular gap (7).

Title: Apparatus for segmenting colour-flow (CF) mode data in medical ultra-sound esp. for heart studies
Inventor: HATFIELD WILLIAM THOMAS
IPC: A61B8/06
Filed: 1998-05-04
Abstract: The apparatus uses segmentation of three-dimensional projected speed pictures, in which the volume of the speed is limited, which are projected on to the picture planes. When the volume of interest contains flowing blood, i.e. an artery or vein, the reflected Doppler shift can be recorded. The transducer array feeds the bunching former (2) with processor (4B) for colour flow. Trigonometric data are held and successive volumetric projections of pixels calculated. The shift is available in the ultrasound reflected from the flow, and then can be used to limit the quantity of speed data, which are projected. Only pixels with speed values within a predetermined area are projected on to the picture plane. The heart cycle may be used as trigger.

IPC: B27N3/24
Filed: 1998-05-09
Abstract: In the prodn. of wood chipboards, using heat and pressure in a double-belt press, plasticizing agents are used differently across the width of the pressed material (4) so that, at the end of the press stage, the pressed material (4) has consistent characteristics along its length as close as possible to a balanced condition. The applied heat differs across the pressed material (4) width, in terms of heating levels per width unit delivered to the material. The mat of scattered material has different moisture levels, on entry into the press section, through a scattering of particles with different moistures, or the scattered material is wetted to different levels across the width. An Independent claim is included for a prodn. assembly where a plasticizing agent is scattered over the width of the scattered material or pressed material (4), by at least one unit, to give the required material characteristics along the material length at the end of the press stage. Preferred Features: In at least one length of the press section, the support structure has heating channels(40,40',40) parallel to the direction of material travel. The heating channels (40,40'.40) are individual or in groups, to carry different heating media. Units set the moisture level of the scattered material at different levels across its width, and a unit scatters particles with different moistures over the scattered material width, or a spray wets the scattered material differently across its width.
