1.WO/2000/008742LINE HARMONIC OR POWER FACTOR CORRECTION ON FLYBACK POWER CONVERTERS USING AUXILIARY WINDING DISCONNECT OR CLAMP SWITCH TECHNIQUES

WO - 17.02.2000

Clasificación Internacional H02M 1/00 Nº de solicitud PCT/GB1999/002488 Solicitante ASTEC INTERNATIONAL LIMITED Inventor/a CROSS, David, A.

Effective harmonic correction without frequency, power or voltage limitations is achieved in a single-stage DC-to-DC converter by disconnecting the bulk capacitor (38) of a typical single-stage converter during low voltage conditions, and by using various phase and cycle modulation techniques associated with a switchable auxiliary transformer winding (48) which charges the bulk capacitor to control its voltage. A means is thus provided to control the level of harmonics generated depending upon the level of the AC output voltage. When the auxiliary winding is used as a clamp winding, full ZVS conditions are provided for both the auxiliary winding switch (66) and the converter's primary winding switch (52). Energy can then also be directed, under independent control of the switched auxiliary winding, to independent power nodes, i.e., either the output capacitance and load, or the bulk capacitor. This ensures that the output voltage will not be affected during any period needed to recharge the bulk capacitor.

2.WO/1995/032338ARTIFICIEL BLOCK

WO - 30.11.1995

Clasificación Internacional E02B 3/12 Nº de solicitud PCT/FR1995/000668 Solicitante VOISIN, Alexandre Inventor/a VOISIN, Alexandre

The invention relates to an artificial block of the type formed of a revolution part organised about a vertical axis forming a core. According to the invention, said block inside a cylinder is comprised of two truncated cones (1a, 1b) connected by their faces of smaller cross-section and forming a virtual joined plane (P) between the truncated cones whose base (2a, 2b) has a general cross-sectional form of a clover with n branches (4a, 5a, 6a), (4b, 5b, 6b) which are equidistant and radiating about said vertical axes and offset with respect to each other by 1/2n turn, said branches being separated from each other by a recess (7a, 8a, 9a) having a profile and a dimensional ratio such that one branch of an adjacent block may be inserted into said recess. Application to sea and river protection works.

3.WO/2001/027968DETERMINING BEAM ALIGNMENT IN ION IMPLANTATION USING RUTHERFORD BACK SCATTERING

WO - 19.04.2001

Clasificación Internacional H01J 37/147 Nº de solicitud PCT/GB2000/003962 Solicitante APPLIED MATERIALS, INC. Inventor/a RYDING, Geoffrey

A back scattered ion receiver is mounted on the process chamber of an ion implanter to receive beam ions back scattered from a wafer mounted on the wafer holder in the chamber. Minima in the intensity of back scattered ions as the wafer on the holder is moved relative to the beam direction, can be used to obtain an accurate calibration of the true beam direction. Beam direction error can then be compensated for when operating holder tilt and twist mechanisms so as to bring a process wafer accurately into the required orientation relative to the true beam. If the crystallographic alignment and orientation of process wafers has been precharacterised, this data can be used to control the wafer holder to align process wafers crystallographically to the process beam.

A touch input/output device for a computing device. The touch device includes a touch sensor for providing touch location information and a force sensor for providing force of touch information. The touch sensor determines touch location information. The force sensor determines the force of touch information. Both the touch sensor and the force sensor are integrated into a circuit responsive to signals, the signals occurring at discernible times in response to whether the signals are in response to contact or in response to an amount of force. Additionally, the touch device includes a circuit coupled to the touch sensor and to the force sensor, and capable of combining information from the touch sensors and from the force sensors.

WO - 11.01.1996

Clasificación Internacional F03B 13/14 Nº de solicitud PCT/DK1995/000267 Solicitante FRIIS-MADSEN, Erik Inventor/a FRIIS-MADSEN, Erik

The invention is a power plant for the exploitation of wind/wave energy on the high seas. The plant consists of a floating, self-adjusting with regards to waves, platform (1) which is anchored with hawsers (6) to a floating anchor pontoon (3), which in its turn is anchored to a swivel link on top of an anchor block (4), placed on the sea floor. The side of the platform which faces the waves is designed as a doubly curved ramp (13), on which waves are led into a shallow basin (14), which has a water level above the mean sea level determined by the surrounding prevailing height of the waves. The sea water is led back into the sea from the basin by way of turbines, which for instance run electrical generators. The platform can be equipped with curved, stiff, and thereby self-stabilising, wave reflectors (2), which deflect and focus the waves towards the ramp (13). The platform's and wave reflector's special design allow a stabile and high exploitation of wave energy for power production. The platform has a sufficiently large stability versus wave movements that it can be equipped with windmills of unusual but nevertheless known design.
