Abstract: A phase controlled demodulation system for digital communication includes a quadrature detector for receiving a modulated digital signal and generating therefrom a pair of I and Q demodulated signals.  A phase difference detection and filter circuit detects a phase difference between the I and Q demodulated signals, and another circuit detects a carrier-to-noise ratio of one of the I and Q demodulated signals.  A further circuit detects a ratio difference between the detected carrier-to-noise ratio and a predetermined value, and a voltage controlled oscillator responsive to the detected phase difference and the detected ratio difference generates a carrier as a replica of the carrier of the received digital signal and applies the carrier to the quadrature detector.

Abstract: An apparatus for metering, measuring, or dosing flowing media. A distribution slide valve is disposed in a housing between an inlet and an outlet. A metering piston is disposed in a chamber of the housing and divides the chamber into a first and a second metering chamber. The two end positions of the slide valve alternately connect the metering chambers to the inlet or outlet. Transfer passages are disposed on the periphery of the slide valve for selective connection of connecting passages to the inlet, the outlet, and the metering chambers. A transverse connection of the slide valve connects a central control channel thereof to the inlet via a first one of the transfer passages in either of the end positions of the slide valve. Each end of the latter is associated with a hydraulic control chamber into which the control channel opens. Relief passages connect the control chambers to the outlet. A piston rod connected to the metering piston extends axially displaceably through the larger diameter control channel, with the slide valve being axially movable relative to the piston rod. Sealing elements are disposed on the piston rod, with the control channel being adapted to be alternately sealed off relative to one or the other of the control chambers via these sealing elements.

Abstract: A queuing system is provided for gaming apparatus such as a billiards table. The system uses a remote consol that is coin operated and has a keypad for players to enter their names in a sequence of players. The consol dispenses a ticket with a unique identifier marked on the ticket, corresponding to the player name. A display associated with the apparatus, for example above a billiards table, displays the name or names of the persons playing. When a game is completed, as by pocketing the black ball in a game of snooker, the apparatus detects this condition and signals the main processor through an infra red link that the game is over. The apparatus is then locked up, as by locking a ball collector, until the next player enters the correct ticket at the consol to release the balls from the collector. A tournament mode of play omitting the tickets and providing for two sequences players is also provided.

Title: Laser apparatus for treating bone and tooth tissue
Inventor: LEVY GUY
IPC: A61N5/06
Filed: 1990-06-19
Granted: 2001-07-31
Abstract: A method and apparatus for cutting tooth tissue by generating laser radiation at a wavelength which is absorbed more strongly by hydroxyapatite than by water; producing a succession of pulses of the generated radiation with an energy level, pulse duration, and repetition rate selected to cut the tooth tissue without causing harmful side effects; and concentrating the radiation pulses on the tissue to a spot sufficiently small to cause cutting of the tissue.  Laser radiation having a selected wavelength and in the form of pulses having a selected pulse duration, repetition rate and energy content per pulse, is employed for performing a variety of dental and medical procedures, including treatment of cysts and granulomas in the gum, and cutting of dentin, cementum, dental root material, bone and metal. Cavities and openings in teeth and bones can be filled with a mixture containing hydroxyapatite and phosphoric acid, mixed together to form a paste, and the resulting mixture, after being introduced into the opening or cavity, can be cured and hardened by application of pulses of defocussed laser radiation.

Abstract: ABSTRACT          "Improvements in or relating to the repair of turbine blades"   A method of repairing rotor blades on a turbine comprises the steps of removal of a rotor (12) from the turbine, selecting a predetermined desired position of the blades and, after removing any inter blade ties (66,67) necessary to enable any required repair processes to be carried out, aligning all the blades (60,61,62,63) to said predetermined aligned position prior to the carrying out of any repair step which may incorporate cutting, welding, machining etc., such alignment considerably facilitates semi-automated repair of each blade (60,61,62,63) and has further benefits in facilitating reinsertion of inter blade ties (66,67) and ensuring that the blades (60,61,62,63) are not only in an aligned position but in a stress free condition when returned to the turbine.
