Abstract: A mandrel shoe 1 for the installation of vertical drains has a guide channel 10 extending from an upper end 11 of the mandrel shoe to a side opening 12 formed in a lower end of the mandrel shoe. The guide channel is adapted to direct a length of drain from an upper end of the mandrel shoe towards and out of the side opening. In this way, an anchoring length of drain projects from the side opening to anchor the drain within the ground. The shoe includes a cutter 18 which cuts the drain when the mandrel and shoe are raised above the ground causing a stop 30 on the rig to depress a plunger 15. Movement of the plunger in the opposite direction when the shoe starts to move towards the ground operates a feed roller 20 to feed a length of drain from the side opening 12 to form the anchor section for the next drain.

Title: Maintaining orthogonality between signals
Inventor: PARK JONG-HYEON
IPC: H04B1/707
Filed: 1999-03-03
Abstract: A spread spectrum apparatus for an OQPSK (offset quadrature phase shift keying) DS/CDMA system maintains orthogonality between transmission signals during zero crossing. First and second input signals DI(t), DQ(t) are combined with orthogonal Walsh codes WI(t), WQ(t) and are spread using corresponding PN sequences PI(t) and PQ(t). A zero crossing detector 241 determines whether zero-crossing occurs for both the first and second spread signals XI(t), XQ(t) and outputs a signal to selectors 247, 249 accordingly. First and second delays 243, 245 stagger the spread signals and these signals together with the spread signals XI(t) and XQ(t) are forwarded to the selectors. Ordinarily the first and second spread signals are selected for transmission, but when zero-crossing is detected the staggered versions of these signals are selected to maintain orthogonality. Alternatively only one of the spread signals may be delayed (fig. 8).

Title: Using 4 loudspeakers to give 3D sound field
Inventor: CLEMOW RICHARD DAVID
IPC: H04S5/00
Filed: 1999-04-26
Abstract: A three-dimensional sound-field is synthesised using a pair of front and a pair of rear loudspeakers. The desired position of a sound source i.e. front, side or rear, in relation to the preferred position of a listener is determined. A binaural pair of signals corresponding to the sound is derived via an HRTF or a binaural placement filter. The left signal of the binaural pair is provided to the left front and left rear loudspeakers through front and rear gain control circuits.The right signal of the binaural pair is provided to both the right front and right rear loudspeakers through front and rear gain control circuits. The ratio of the front signal gains to the rear signal gains is controlled as a function of the azimuth angle of the sound source e.g. via a crossfade algorithm. Finally transaural crosstalk cancellation on the front and rear signal pairs is performed through respective circuits TCC. The invention enables effective rearward placement of virtual sound sources which are rich in high frequencies. The invention preferentially steers frontal virtual sound sources to front loudspeakers and rearward virtual sound sources to rear loudspeakers.

Patent GB-2353999-A (GB)
Title: Curable systems of self-emulsified aqueous epoxy resins
Inventor: CHEN I SORNG-WEN
IPC: C08G59/42
Filed: 1999-09-07
Abstract: An anionic, self-emulsified aqueous epoxy resin dispersion is prepared through the semi-esterification reaction between a dicarboxylic acid anhydride and the secondary hydroxy group of an epoxy resin, followed by neutralization of the carboxylic acid thus introduced into the resin with a tertiary amine and then adding only water, without the need of emulsifier, to the resulting hydrophilic amine salt of the carboxylic acid. A "single-pack" curable aqueous epoxy resin system "cross-linkable" at normal temperature is prepared by adding a polyaziridine into the resin dispersion. Upon drying, the liberated carboxyl group in the resin reacts with the polyaziridine to form an amino ester via a ring opening reaction. The amino group further reacts with the epoxy group of the resin to complete a "double cross-linking". The double cross-linking process also can be used in a hybrid resin obtained by blending the aqueous epoxy resin dispersion and other carboxyl- or epoxy-containing aqueous resins, to cure the hybrid resin.

Title: Prioritised channel scanning
Inventor: GAASTRA LYLE A
IPC: H04W56/00
Filed: 1999-12-07
Abstract: A channel scanning method uses a priority table to determine the action that should be taken by a mobile station (MS) during an idle frame of a traffic channel (TCH) in order to decode the base station identification code (BSIC) of each channel in a reporting table every ten seconds in accordance with GSM specification 05.08. The priority table has channel groups based on the role of the cell relative to the MS, the time elapsed since the cell's broadcast channel (BCH) was most recently synchronized, the expected amount of time needed to either detect a frequency burst (FCH) or demodulate a synchronization burst (SCH), the power level of a BCH, and the detected noise level. The priority table is used by a scheduler to aid the MS in efficiently using each idle frame and reducing nonuse of idle frames.

Title: Histogram equalization system
IPC: G06T5/40
Filed: 1976-07-20
Abstract: Real time histogram equalization systems for a television type display that performs equalization with one or two dimensional processing on a local area or sliding window basis. For the two dimensional system, the intensity for any particular point in the image is adjusted according to a histogram of the area contained within a window immediately surrounding the point to be equalized. The histogram forming window provided by the system moves across the image in two dimensions both horizontally along each of a plurality of overlapping segments arranged parallel in the vertical dimension, and at each window position reassigned center picture elements are equalized. The processing of the histograms area or the sliding process is continued over the entire surface of the raster with the process being then repeated in a continuous fashion. The area being equalized for each window position may be selected equal horizontally and vertically to the respective amount of shifting along each segment between window positions and of the shifting of the window between adjacent segments. In order to process the histograms at the video rate and resolution the system computes mini or subhistograms from an area formed of a selected number of elements of the histogram in the horizontal dimension by the number of histogram lines in the vertical dimension of the window and sums the statistics of a selected number of the mini histograms to generate one histogram for equalizing the central area. In the continuous process the mini histograms are read out in parallel to form a plurality of histograms and multiple truncation maps which are stored in a selected number of RAM memories. Digital video is then processed through these transformed memories and stored in output buffers which may be required because of the multiplexing. In the system utilizing one dimensional processing, histograms are formed for the data of a selected number of lines in order to equalize the data of a selected line or lines and the histogram window area is moved vertically over the entire raster area.

Title: Preparation of core-shell particle dispersions for use as opacifying agents in coatings
IPC: C08F291/00
Filed: 1987-11-03
Abstract: An aqueous dispersion of water-insoluble core-shell particles is prepared by emulsion polymerization for use as an opacifying agent in coatings. The particles have interior cores which are swollen with nonaqueous solvent. The polymeric exterior shells have a glass transition temperature greater than about 50 DEG C in the presence of the nonaqueous solvent. The partition coefficient for the nonaqueous solvent between the interior core polymer phase and the exterior shell polymer phase is at least about 1.25. Coatings compositions formulated using the core-shell particles show increased opacity, as single light scattering microvoids are formed in individual particles when the solvent evaporates and the core collapses inside the rigid exterior shell. Opacity develops even when aqueous coatings containing the particles are dried under high humidity conditions.
